Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation of International Patent Application No. PCT/JP2019/035028, filed on Sep. 5, 2019, which is based upon and claims the benefit of priority from Japanese Patent Application No. 2018-166587 filed on Sep. 6, 2018, the entire contents of which are incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     Embodiments described herein generally relate to a hemostatic device. 
     Background Art 
     In a known catheter procedure, a blood vessel in an arm of a patient (for example, radial artery) is punctured and various medical elongated bodies are introduced into the blood vessel via the puncture site for treatment or therapy on a lesion area. The catheter procedure utilizing the radial artery is referred to as transradial artery approach and is considered a useful technique for, for example, coronary artery access and lower limb artery access. 
     A radial artery located in an arm of a human body is connected to a palmar artery which bypasses a hand side. Therefore, currently, as a new method of transradial artery approach, a catheter procedure using distal transradial approach (dTRA) has been attempted to access the palmar artery including a distal radial artery from an anatomical snuffbox located on a dorsal side of the hand or from a position around the snuffbox, and perform treatment through the vascular access site. 
     Blood vessels such as palmar arteries located in the hand are located in places where there are many movable parts such as fingers. For this reason, when an operator punctures a blood vessel such as a palmar artery and forms a puncture site on a surface of a hand, a shape around the puncture site of the hand changes depending on the movement of the hand. Therefore, when hemostasis is performed at the puncture site, a pressing member placed on the hand is preferably an inflatable member that follows the movement of the hand and easily adjusts a compressive force on the puncture site. 
     However, when the pressing member is the inflatable member, the inflatable member exerts a force to inflate from the inside to the outside of the inflatable member in an inflated state. For this reason, in a hemostatic device having the inflatable member, a shape around a hemostatic site changes due to the movement of the hand, the inflatable member shifts from the puncture site, and a compressive force of the inflatable member on the puncture site may not be properly maintained. Therefore, when hemostasis is performed at the puncture site of the hand, the hemostatic device having the inflatable member needs to suppress misalignment of the inflatable member due to the force acting in a direction away from the puncture site, thereby appropriately securing the inflatable member to the puncture site. In this way, it is considered that the hemostatic device having the inflatable member can appropriately maintain the compressive force of the inflatable member on the puncture site even when the shape around the puncture site is changed by the movement of the hand. 
     In addition, when the pressing member is the inflatable member, it is possible to increase the compressive force on the hand by inflating the inflatable member. For this reason, it is considered that the misalignment of the inflatable member from the puncture site on the hand can be suppressed by adjusting the degree of inflation of the inflatable member. However, when the inflatable member is inflated, if an edge portion of the inflatable member (e.g., an outer peripheral edge) is strongly pressed against the hand, the patient may feel pain. 
     SUMMARY OF THE INVENTION 
     One or more embodiments provide a hemostatic device capable of suppressing misalignment of an inflatable member with respect to a site where bleeding is to be stopped on the hand even when the patient moves the hand in a state where the inflatable member is inflated. Additionally, the hemostatic device is further capable of reducing pain felt by the patient when an edge portion of the inflatable member in the inflated state is pressed against the hand. 
     A hemostatic device according to one or more embodiments is attachable to a hand of a patient and includes a covering member configured to cover a site where bleeding is to be stopped on a hand of a patient, a securing member configured to secure the covering member to the hand when the covering member covers the site, an inflatable member connected to the covering member and inflatable by injection of a fluid, and a deformable auxiliary member having a smaller outer shape than an outer shape of the inflatable member. The covering member includes a main body, a first arm portion protruding from a first side of the main body, and a second arm portion protruding from a second side of the main body, wherein the first and second sides are opposite sides of the main body. The main body includes a first end portion located on a distal side of the main body between the first arm portion and the second arm portion, and a second end portion located on a proximal side of the main body between the first arm portion and the second arm portion. The inflatable member is connected to the second end portion, and the auxiliary member is connected to the first end portion and is interposed between the main body and the inflatable member.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, one or more embodiments of the invention will be described with reference to the accompanying drawings. The following description does not limit the technical scope or the meaning of terms described in the appended claims. In addition, the dimensions or scales on the drawings may be different from actual ones. 
       FIGS. 1 to 7  are diagrams illustrating a hemostatic device  100  according to an embodiment, and  FIGS. 8 to 12  are diagrams illustrating usage examples of the hemostatic device  100 . 
     For example, as illustrated in  FIGS. 9, 10, and 11 , when removing a sheath tube of an introducer  200  indwelling at a puncture site t where bleeding is to be stopped formed on a radial artery side (for example, an artery around an anatomical snuffbox or a distal radial artery running on a fingertip side of the snuffbox) of a deep palmar artery B running on a side of a dorsal side Hb of a hand (for example, left hand) H located on the fingertip side of a forearm A of a patient, the hemostatic device  100  can be used to perform hemostasis on the puncture site t. The anatomical snuffbox is a cavity in the hand located on the radial side of the forearm A when the patient spreads a thumb f 1  of the hand H. 
     In brief, as illustrated in  FIGS. 1, 2, 10, and 11 , the hemostatic device  100  includes a covering member  110  to cover the puncture site t on the hand H of the patient, a plurality of securing members  151 ,  152 ,  153 ,  154 , and  155  for securing the covering member  110  while the covering member  110  covers the puncture site t, an inflatable member  170  connected to the covering member  110  and inflated by injection of a fluid, and an auxiliary member  180  which has a smaller outer shape than that of the inflatable member  170  and is deformable. 
       FIG. 1  illustrates a plan view of the hemostatic device  100  seen from an outer surface side of a main body  120  of the covering member  110 , and  FIG. 2  illustrates a plan view of the hemostatic device  100  seen from an inner surface side of the main body  120  of the covering member  110 . An “inner surface” of the main body  120  is a surface on a side to which the inflatable member  170  disposed to face a body surface of the patient when the hemostatic device  100  is worn on the patient is connected, and an “outer surface” of the main body  120  is a surface opposite to the inner surface. In addition, a “distal side” used in the following description refers to a side where a fingertip of the hand H is disposed in a state where the hemostatic device  100  is worn on the hand H of the patient (i.e., the upper side in  FIG. 1  and  FIG. 3 , and the left side in  FIG. 5 ), and a “proximal side” is opposite to the distal side, closer to the wrist than the fingertip of the hand. In the following description, a state where arm portions  130  and  140  of the covering member  110  are extended without being attached to the hand H of the patient will be referred to as a “non-worn state”. 
     &lt;Covering Member&gt; 
     As illustrated in  FIGS. 1 and 2 , the covering member  110  includes the main body  120  to which the inflatable member  170  is connected, the first arm portion  130  protruding from the main body  120 , and the second arm portion  140  protruding from a position facing the first arm portion  130  with the main body  120  interposed therebetween. 
     &lt;Main Body&gt; 
     As illustrated in  FIGS. 1 and 5 , the main body  120  includes a first end portion  121  located on a distal side of the main body  120  between the first arm portion  130  and the second arm portion  140 , a second end portion  122  located on a proximal side of the main body  120  between the first arm portion  130  and the second arm portion  140 , and an extending portion  123  which extends between the first end portion  121  and second end portion  122 . 
     The main body  120  is made of a flexible member. A space  124  in which the inflatable member  170  and the auxiliary member  180  are disposed is formed inside the extending portion  123  of the main body  120 . The space  124  communicates with the outside of the main body  120  along a direction intersecting an extending direction of the extending portion  123  (i.e., the direction along which the arm portions  130  and  140  protrude). 
     As illustrated in  FIG. 5 , a curved region  125  is formed on the second end portion  122  side of the main body  120 . The curved region  125  is a part of the extending portion  123 . The curved region  125  is adjacent to the second end portion  122  and has a cross-sectional shape convexly protruding to the proximal side of the main body  120 . 
     The second end portion  122  of the main body  120  extends continuously from the extending portion  123  and forms an end part of the extending portion  123  that curves toward the distal side of the main body  120 . The first end portion  121  side of the extending portion  123  has a cross-sectional shape extending substantially linearly toward the first end portion  121 . 
     The inflatable member  170  is connected to the second end portion  122  of the main body  120 . In the inflatable member  170 , a proximal portion  174   b  of the inflatable member  170 , which is a peripheral edge located at an end portion of the inflatable member  170  on the proximal side, is connected to the second end portion  122  of the main body  120 . 
     As illustrated in  FIG. 13 , the inflatable member  170  may be connected from the second end portion  122  of the main body  120  to the curved region  125  of the extending portion  123 . In this instance, the proximal portion  174   b  of the inflatable member  170  is preferably located on the first end portion  121  side of an apex  125   a  of a convex portion protruding toward the proximal side of the main body  120  of the curved region  125 . In this way, the proximal portion  174   b  of the inflatable member  170  is located on the outer surface side of the main body  120  in a state where the hemostatic device  100  is worn on the hand H of the patient. For this reason, even when the patient moves the hand H in a state where the inflatable member  170  is inflated, it is possible to reliably prevent the proximal portion  174   b  of the inflatable member  170 , which is the edge portion of the inflatable member  170  on the proximal side, from biting into the hand. Therefore, in a case where the hemostatic device  100  has the inflatable member  170  and the main body  120  of the covering member  110  connected to each other as illustrated in  FIG. 13 , it is possible to reduce the pain of the patient during hemostasis. 
     The auxiliary member  180  is connected to the first end portion  121  of the main body  120 . The auxiliary member  180  is connected to the first end portion  121  in a state of being interposed between the main body  120  and the inflatable member  170 . In the auxiliary member  180 , a distal portion  184   a  of the auxiliary member  180 , which is a peripheral edge located at an end portion of the auxiliary member  180  on the distal side, is connected to the first end portion  121  of the main body  120 . 
     The auxiliary member  180  is connected to the inflatable member  170  at a position biased to one end side (i.e., the distal portion  174   a  side) of the inflatable member  170 . In an embodiment, the inflatable member  170  and the auxiliary member  180  are connected to each other at a center portion  184   c  of the auxiliary member  180 . The center portion  184   c  is located at a center position of the auxiliary member  180  in a right-left direction illustrated in  FIG. 5 . 
     As described above, the distal portion  184   a  of the auxiliary member  180  is connected to the first end portion  121  of the main body  120  of the covering member  110 , and the proximal portion  174   b  of the auxiliary member  180  is connected to the second end portion  122  of the main body of the covering member  110 . The inflatable member  170  and the auxiliary member  180  are connected to each other at the center portion  184   c  of the auxiliary member  180 . Therefore, in the covering member  110 , only the first and second end portions  121  and  122  of the main body  120  are directly connected to the inflatable member  170  and the auxiliary member  180 . 
     In the main body  120 , a portion overlapping a marker portion  105  described later in the plan view of  FIGS. 1 and 3  and surroundings thereof in the main body  120  are preferably transparent (including colored transparent, colorless transparent, and translucent). By adopting the above configuration, the operator can visually recognize the puncture site t from the outer surface side of the main body  120  even when the marker portion  105  is superposed on the puncture site t. 
     &lt;First Arm Portion and Second Arm Portion&gt; 
     In the following description, a longitudinal direction of the first arm portion  130  means a horizontal direction in  FIGS. 1 and 2  along which the first arm portion  130  extends in the non-worn state. In addition, a width direction of the first arm portion  130  is a direction intersecting the longitudinal direction of the first arm portion  130  on the plan views illustrated in  FIGS. 1 and 2 . Similarly, a longitudinal direction of the second arm portion  140  is the horizontal direction of  FIGS. 1 and 2  along which the second arm portion  140  extends in the non-worn state, and a width direction of the second arm portion  140  is a direction intersecting the longitudinal direction of the second arm portion  140  on the plan views illustrated in  FIGS. 1 and 2 . 
     As illustrated in  FIGS. 1 and 2 , the first arm portion  130  has a first region  131  connected to the main body  120 , a second region  132  located at an end portion opposite to a side where the first region  131  is disposed, and a main body region  133  located between the first region  131  and the second region  132 . 
     The first arm portion  130  is formed of a flexible band-shaped member that can be wrapped around the hand H of the patient. 
     The main body region  133  of the first arm portion  130  is curved so that the second region  132  side is separated from the main body  120  in the non-worn state. 
     As illustrated in  FIG. 1 , the first securing member  151  is disposed on an outer surface of the second region  132  of the first arm portion  130 . The second securing member  152  is disposed on a part of an outer surface of the main body region  133  of the first arm portion  130 . As illustrated in  FIG. 2 , the third securing member  153  is disposed on an inner surface of each of the regions  131 ,  132 , and  133  of the first arm portion  130 . 
       FIG. 7  illustrates a cross-sectional view of a peripheral edge  130   a  on the proximal side of the main body region  133  of the first arm portion  130  and a center portion  130   b  passing through a center of the first arm portion  130  along the width direction. 
     As illustrated in  FIGS. 1, 2, and 7 , a member forming the main body region  133  of the first arm portion  130  and the third securing member  153  disposed on the inner surface of the main body region  133  are disposed to overlap each other at the peripheral edge  130   a  of the main body region  133  of the first arm portion  130  on the proximal side. Meanwhile, a member forming the main body region  133  of the first arm portion  130 , the second securing member  152  disposed on the outer surface of the main body region  133 , and the third securing member  153  disposed on the inner surface of the main body region  133  are disposed to overlap each other at the center portion  130   b  of the main body region  133  of the first arm portion  130 . For this reason, in the first arm portion  130 , when the peripheral edge  130   a  on the proximal side of the main body region  133  and the center portion  130   b  are compared to each other, a wall thickness of the peripheral edge  130   a  on the proximal side of the main body region  133  (i.e., the vertical dimension of  FIG. 7 ) is smaller than a wall thickness of the center portion  130   b.    
     As illustrated in  FIGS. 1 and 2 , the second arm portion  140  has a first region  141  connected to the main body  120 , a second region  142  located at an end portion opposite to a side where the first region  141  is disposed, and a main body region  143  located between the first region  141  and the second region  142 . 
     The second arm portion  140  is formed of a flexible member that can be deformed along a shape of an external surface of the hand H of the patient. 
     The main body region  143  of the second arm portion  140  is curved so that the second region  142  side is separated from the main body  120  in the non-worn state. 
     As illustrated in  FIG. 1 , the fourth securing member  154  is disposed on a part of the outer surface of the first region  141  and the main body region  143  of the second arm portion  140 . As illustrated in  FIG. 2 , the fifth securing member  155  is disposed on the inner surface of each of the regions  141 ,  142 , and  143  of the second arm portion  140 . 
       FIG. 6  illustrates a cross-sectional view of a peripheral edge  140   a  on the proximal side of the main body region  143  of the second arm portion  140  and a center portion  140   b  passing through a center of the second arm portion  140  in the width direction. 
     As illustrated in  FIGS. 1, 2, and 6 , a member forming the main body region  143  of the second arm portion  140  and the fifth securing member  155  disposed on the inner surface of the main body region  143  are disposed to overlap each other at the peripheral edge  140   a  of the main body region  143  of the second arm portion  140  on the proximal side. Meanwhile, a member forming the main body region  143  of the second arm portion  140 , the fourth securing member  154  disposed on the outer surface of the main body region  143 , and the fifth securing member  155  disposed on the inner surface of the main body region  143  are disposed to overlap each other at the center portion  140   b  of the main body region  143  of the second arm portion  140 . For this reason, in the second arm portion  140 , when the peripheral edge  140   a  on the proximal side of the main body region  143  and the center portion  140   b  are compared to each other, a wall thickness of the peripheral edge  140   a  on the proximal side of the main body region  143  (i.e., the vertical dimension of  FIG. 6 ) is smaller than a wall thickness of the center portion  140   b.    
     As illustrated in  FIG. 3 , the second arm portion  140  protrudes from the main body  120  while forming an obtuse angle θ with the longitudinal direction of the first arm portion  130 . The obtuse angle θ formed between the first arm portion  130  and the second arm portion  140  is an angle at which a straight line d 1  extending along the center portion  130   b  of the main body region  133  of the first arm portion  130  and a straight line d 2  extending along the center portion  140   b  of the main body region  143  of the second arm portion  140  intersect on the main body  120 . For example, the obtuse angle θ can be set to 120° to 170°. 
     As described above, in the hemostatic device  100 , the first arm portion  130  and the second arm portion  140  form the obtuse angle θ in the plan views illustrated in  FIGS. 1 and 3 . For this reason, the first arm portion  130  is inclined and extends toward the second end portion  122  side so as to be separated from the first end portion  121  side of the main body  120 . Similarly, the second arm portion  140  is inclined and extends toward the second end portion  122  side in a direction away from the first end portion  121  side of the main body  120 . Therefore, the first arm portion  130  and the second arm portion  140  extend from the first end portion  121  of the main body  120  toward the second end portion  122  side so as to spread in an inverted V-shape without intersecting each other. 
     In the hemostatic device  100 , since the second arm portion  140  forms the obtuse angle θ with the longitudinal direction of the first arm portion  130 , the first arm portion  130  and the second arm portion  140  can be connected in a state of being extended toward a wrist side of the hand H of the patient (see  FIG. 10 ). For this reason, the first arm portion  130  and the second arm portion  140  can be secured on the wrist side where a movable range is small, and a movable range on the fingertip side of the hand H can be maintained. In addition, the inflatable member  170  can apply a strong compressive force to the proximal side of the inflatable member  170  (i.e., the wrist side) by securing the first arm portion  130  and the second arm portion  140 . Further, the inflatable member  170  can apply a strong compressive force to the distal side of the inflatable member  170  by the auxiliary member  180 . For this reason, the hemostatic device  100  can appropriately apply the compressive force of the inflatable member  170  to the hand H of the patient. 
     An angle formed by a straight line d 3  (see  FIG. 3 ) passing through a center position of the main body  120  and the straight line d 1  along the longitudinal direction of the first arm portion  130  and an angle formed by the straight line d 3  and the straight line d 2  along the longitudinal direction of the second arm portion  140  may or may not be the same. 
     As illustrated in  FIG. 1 , the first arm portion  130  is formed longer than the second arm portion  140 . As illustrated in  FIG. 1 , a magnitude relationship between a length L 1  of the first arm portion  130  and a length L 2  of the second arm portion  140  may be defined by the linear distances L 1  and L 2  of the arm portions  130  and  140  in the non-worn state. The length L 1  of the first arm portion  130  can be set to, for example, 150 mm to 400 mm, and the length L 2  of the second arm portion  140  can be set to, for example, 40 mm to 400 mm. 
     For example, a width W 1  of the first arm portion  130  can be set to be smaller than a width W 2  of the second arm portion  140 . The width W 1  of the first arm portion  130  can be defined by a maximum value of a width of the first arm portion  130  when the width of the first arm portion  130  changes in the longitudinal direction. Further, the width W 2  of the second arm portion  140  can be defined by a maximum value of a width of the second arm portion  140  when the width of the second arm portion  140  changes in the longitudinal direction. The width W 1  of the first arm portion  130  can be set to, for example, 10 mm to 30 mm, and the width W 2  of the second arm portion  140  can be set to, for example, 15 mm to 45 mm. 
     In an embodiment, in the covering member  110 , the main body  120  and the arm portions  130  and  140  are formed of separate members. The main body  120  and the first arm portion  130 , and the main body  120  and the second arm portion  140  can be connected by, for example, adhesion, welding, etc. However, in the hemostatic device  100 , any part of the main body  120 , the first arm portion  130 , and the second arm portion  140  in the covering member  110  may be integrally formed of one member. 
     The main body  120  is preferably made of a material having higher elasticity than that of the first arm portion  130  and the second arm portion  140 . In this way, when the hemostatic device  100  is attached to the hand H of the patient, the arm portions  130  and  140  are wrapped around a limb of the patient, so that the main body  120  is extended by being pulled toward each of the first arm portion  130  side and the second arm portion  140  side. In this way, since the main body  120  is easily deformed due to changes in physical properties at each of boundaries between the main body  120  and the first arm portion  130  and between the main body  120  and the second arm portion  140 , it is possible to easily dispose the first arm portion  130  and the second arm portion  140  on the hand H of the patient in a state where the main body  120  is disposed at the puncture site t formed on the hand H of the patient. 
     A material used for the main body  120  of the covering member  110  is not particularly limited. Examples thereof include polyvinyl chloride, polyolefin such as polyethylene, polypropylene, polybutadiene, or ethylene-vinyl acetate copolymer (EVA), polyester such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), polyvinylidene chloride, silicone, polyurethane, various thermoplastic elastomers such polyamide elastomer, polyurethane elastomer, and polyester elastomer, nylon, nylon elastomer, or any combination thereof (e.g., blended resin, polymer alloy, laminate, etc.). 
     A material used for the first arm portion  130  and the second arm portion  140  of the covering member  110  is not particularly limited. Examples thereof may include the same materials as the materials exemplified as the main body  120  of the covering member  110 , woven fabric, nonwoven fabric, felt, cloth, knitted fabric, and paper. 
     &lt;Securing Member&gt; 
     As illustrated in  FIGS. 1 and 2 , the hemostatic device  100  includes five securing members of the first securing member  151 , the second securing member  152 , the third securing member  153 , the fourth securing member  154 , and the fifth securing member  155 . 
     As illustrated in  FIG. 1 , the first securing member  151  and the second securing member  152  are disposed on the outer surface of the first arm portion  130 . The first securing member  151  is disposed in the second region  132  of the first arm portion  130 . The second securing member  152  is disposed in a part of the first arm portion  130  excluding the first region  131  and the peripheral edge  130   a  on the proximal side of the main body region  133 . 
     As illustrated in  FIG. 1 , the fourth securing member  154  is disposed on the outer surface of the second arm portion  140 . The fourth securing member  154  is disposed in the first region  141  of the second arm portion  140  and the center portion  140   b  of the main body region  143 . 
     As illustrated in  FIG. 2 , the third securing member  153  is disposed on the inner surface of the first arm portion  130 . The third securing member  153  is disposed on the entire inner surface of the first arm portion  130 . 
     As illustrated in  FIG. 2 , the fifth securing member  155  is disposed on the inner surface of the second arm portion  140 . The fifth securing member  155  is disposed on the entire inner surface of the second arm portion  140 . 
     The first securing member  151  and the fourth securing member  154  are configured as a male side of a surface fastener. The second securing member  152 , the third securing member  153 , and the fifth securing member  155  are configured as a female side of the surface fastener. The surface fastener is a fastener that is removable in terms of surface, and is, for example, MAGIC TAPE® or VELCRO®. 
     Specific configurations of the securing members  151 ,  152 ,  153 ,  154 , and  155  are not limited as long as the first arm portion  130  wrapped around the limb of the patient can be secured to the second arm portion  140 . For example, some of the securing members may be omitted, and positions where the securing members are disposed on the arm portions  130  and  140  may be changed as appropriate. Further, when each of the securing members  151 ,  152 ,  153 ,  154 , and  155  includes the surface fastener, the male side and the female side of the surface fastener may be interchanged. Further, the securing members  151 ,  152 ,  153 ,  154 , and  155  may be snaps, buttons, clips, frame members in which holes are formed, etc. 
     &lt;Inflatable Member and Auxiliary Member&gt; 
     As illustrated in  FIGS. 3, 5, and 11 , the auxiliary member  180  has an outer shape on the plan view smaller than that of the inflatable member  170 . The auxiliary member  180  is disposed to overlap the inflatable member  170  on the distal side of the main body  120 .  FIG. 5  illustrates a cross section of the inflatable member  170  and the auxiliary member  180  in a state before inflation, and  FIG. 11  illustrates a cross section of the inflatable member  170  and the auxiliary member  180  in a state after inflation. 
     As illustrated in  FIG. 11 , the inflatable member  170  has a lumen  171  into which a fluid can be injected, and a communication hole  172  formed at a position facing the auxiliary member  180 . 
     In an embodiment, the auxiliary member  180  is an auxiliary inflatable portion that can be inflated by injection of a fluid. 
     The auxiliary member  180  has a lumen  181  into which a fluid can be injected, and a communication hole  182  formed at a position facing the communication hole  172  of the inflatable member  170 . 
     The communication hole  182  of the auxiliary member  180  is disposed at the center portion  184   c  of the auxiliary member  180 . The lumen  181  of the auxiliary member  180  communicates with the lumen  171  of the inflatable member  170  through the communication hole  182  of the auxiliary member  180  and the communication hole  172  of the inflatable member  170 . The auxiliary member  180  is connected to the inflatable member  170  in a state of communicating with the inflatable member  170  through the communication holes  172  and  182 . 
     In an embodiment, the inflatable member  170  has a substantially square shape on the plan view illustrated in  FIG. 3 . The auxiliary member  180  has a rectangular shape including a set of long sides having substantially the same length as that of one side of the inflatable member  170  and a set of short sides having approximately half the length of one side of the inflatable member  170 . The long sides of the auxiliary member  180  are disposed along the right-left direction of  FIG. 3  along which the arm portions  130  and  140  protrude from the main body  120 . 
     As described above, the auxiliary member  180  is connected to the inflatable member  170  at a position biased toward one end side (i.e., the distal portion  174   a  side) of the inflatable member  170 . For this reason, as illustrated in  FIG. 5 , the distal portion  184   a  of the auxiliary member  180  is disposed near the distal portion  174   a  of the inflatable member  170 , the proximal portion  184   b  of the auxiliary member  180  is disposed near the center portion  174   c  of the inflatable member  170 , and the center portion  184   c  of the auxiliary member  180  is disposed between the distal portion  174   a  and the center portion  174   c  of the inflatable member  170 . 
     The inflatable member  170  is connected to the center portion  184   c  of the auxiliary member  180 . Specifically, in the inflatable member  170 , only a certain range around the communication hole  172  of the inflatable member  170  is secured to a periphery of the communication hole  182  located at the center portion  184   c  of the auxiliary member  180 . 
     As illustrated in  FIG. 3 , the communication hole  172  of the inflatable member  170  and the communication hole  182  of the auxiliary member  180  extend along a longitudinal direction of the auxiliary member  180 . In the hemostatic device  100 , when the inflatable member  170  inflates, the inflatable member  170  inflates while compressing the auxiliary member  180  against the main body  120 , and thus the communication holes  172  and  182  widen in a direction intersecting the longitudinal direction of the auxiliary member  180 . In this way, both end portions of the auxiliary member  180  in the longitudinal direction inflate so as to push both end sides of the distal portion  174   a  of the inflatable member  170 , and it is possible to ensure a large area in which the distal side of the inflatable member  170  compresses the skin of the hand H of the patient. For this reason, the hemostatic device  100  can reliably prevent a compression position of the inflatable member  170  against the skin of the hand H from shifting from the puncture site t even in a state where the hemostatic device  100  moves to the wrist side due to movement of the finger of the patient. 
     The lumen  171  of the inflatable member  170  communicates with a lumen of a tube  193  for supplying a fluid such as air to the inflatable member  170 . As illustrated in  FIGS. 1 and 3 , the tube  193  is connected to the inflatable member  170  on the distal side of the inflatable member  170 . The tube  193  is pulled out from the covering member  110  through the inner surface side of the main body  120  and the inner surface side of the first arm portion  130 . A position where the tube  193  is pulled out from the inflatable member  170  is not particularly limited. However, as illustrated in  FIGS. 1 and 3 , when the tube  193  is pulled out from the first end portion  121  side of the main body  120  to the first arm portion  130  side, so that the hemostatic device  100  is attached to the patient, the tube  193  is disposed laterally to the hand H (i.e., in a direction intersecting a direction in which the finger of the hand H extends) (see  FIG. 9 ). For this reason, when the hemostatic device  100  is attached to the patient, the tube  193  can be prevented from interfering with the introducer  200 . 
     The tube  193  may be connected to the auxiliary member  180 . Further, a position where the tube  193  is pulled out from the main body  120  can be appropriately changed. 
     As illustrated in  FIGS. 3 and 5 , the hemostatic device  100  has the marker portion  105  for aligning the inflatable member  170  with respect to the puncture site t. 
     The marker portion  105  is disposed at a position corresponding to a substantially center position of the inflatable member  170  (i.e., a center position on the plan view illustrated in  FIG. 3 , near the proximal portion  184   b  of the auxiliary member  180 ). 
     When the marker portion  105  is disposed so that the center position of the inflatable member  170  and the proximal portion  184   b  of the auxiliary member  180  are superposed on one another on the cross-sectional view illustrated in  FIG. 5 , the marker portion  105  can be disposed on the outer surface of the proximal portion  184   b  of the auxiliary member  180 . The marker portion  105  can be disposed on an inner surface of the inflatable member  170  on a side facing the body surface, an inner surface or an outer surface of the inflatable member  170  on the side not facing the body surface, and an internal surface or an external surface of the main body  120  of the covering member  110 . 
     In the marker portion  105 , for example, the entire marker portion  105  can be formed of a colored rectangular marker. However, for example, the marker portion  105  may include a transparent central portion and a colored linear frame portion surrounding the central portion. By forming the marker portion  105  in this way, the operator can dispose the marker portion  105  at the puncture site t while checking the puncture site t through the transparent central portion of the marker portion  105 . For this reason, the operator can easily dispose the center position of the inflatable member  170  at the puncture site t using the marker portion  105 . The specific shape and color of the marker portion  105 , a method of forming the hemostatic device  100  on each portion, etc. are not particularly limited. 
     In an embodiment, the inflatable member  170  is formed of two sheet-shaped members. For example, the inflatable member  170  can be formed by bonding outer peripheral edges of the two sheet-shaped members in a state where the lumen  171  is formed between the two sheet-shaped members formed in a substantially rectangular shape. Similarly to the inflatable member  170 , the auxiliary member  180  can be formed of two substantially rectangular sheet-shaped members bonded together. 
     A method of bonding the sheet-shaped members forming the inflatable member  170  and a method of bonding the sheet-shaped members forming the auxiliary member  180  are not particularly limited. For example, it is possible to adopt adhesion or welding. In addition, a method of securing the inflatable member  170  and the auxiliary member  180 , and a method of connecting the inflatable member  170  and the auxiliary member  180  to the main body  120  of the covering member  110  are not particularly limited. For example, it is possible to adopt adhesion or welding. 
     The inflatable member  170  and the auxiliary member  180  are not limited to a structure in which a plurality of sheet-shaped members is bonded. For example, the inflatable member  170  and the auxiliary member  180  may be formed of a single bag-shaped member having a space, through which a fluid can flow, formed therein. 
     A material used for the inflatable member  170  and the auxiliary member  180  is not particularly limited, and examples thereof may include similar materials to those exemplified as the material of the covering member  110 . 
     &lt;Injection Portion&gt; 
     As illustrated in  FIGS. 1 and 2 , the hemostatic device  100  has an injection portion  191  for injecting a fluid into the inflatable member  170 . 
     The injection portion  191  includes a connector having an incorporated check valve (not illustrated). A syringe (not illustrated) can be connected to the injection portion  191 . 
     A cushioning member  192  having an inflatable space is disposed between the injection portion  191  and the inflatable member  170 . The cushioning member  192  includes a flexible bag-shaped member having a space formed inside. The cushioning member  192  may be provided with an arrow-shaped marker indicating a direction in which the syringe is inserted into the injection portion  191 . 
     The injection portion  191  is connected to one end side of the cushioning member  192 . A lumen of the injection portion  191  communicates with the space in the cushioning member  192 . However, while the check valve incorporated in the injection portion  191  is closed, communication between the lumen of the injection portion  191  and the space in the cushioning member  192  is cut off. 
     A flexible tube  193  is connected to the other end side of the cushioning member  192 . A lumen of the tube  193  communicates with the space in the cushioning member  192 . Further, in the tube  193 , the other end portion opposite to one end portion connected to the cushioning member  192  is connected to the inflatable member  170 . The lumen of the tube  193  communicates with the lumen  171  of the inflatable member  170 . 
     For example, the other end portion of the tube  193  can be connected to the inflatable member  170  using an adhesive, etc. while being interposed between the two sheet-shaped members forming the inflatable member  170 . In the sheet-shaped members forming the inflatable member  170 , for example, convex portions partially protruding outward from the sheet-shaped members may be formed at parts interposing the tube  193  therebetween. 
     To inflate the inflatable member  170  and the auxiliary member  180 , the operator inserts a distal tubular portion of a syringe (not illustrated) into the injection portion  191  to open the check valve. For example, the operator injects air in the syringe into the lumen  171  of the inflatable member  170  by pushing a plunger of the syringe in a state where the check valve of the injection portion  191  is open. 
     When air is injected into the lumen  171  of the inflatable member  170 , the inflatable member  170  inflates. Further, the air injected into the lumen  171  of the inflatable member  170  flows into the lumen  181  of the auxiliary member  180  via the communication hole  172  of the inflatable member  170  and the communication hole  182  of the auxiliary member  180 . When air flows into the lumen  181  of the auxiliary member  180 , the auxiliary member  180  inflates. When the inflatable member  170  and the auxiliary member  180  inflate, the cushioning member  192  communicating with the lumen  171  of the inflatable member  170  via the tube  193  expands. 
     The space in cushioning member  192  and the lumen  171  of the inflatable member  170  are in communication with each other via the tube  193  at all times. The injection portion  191  maintains the check valve incorporated in the injection portion  191  in a closed state when the syringe is not inserted into the injection portion  191  to prevent air from leaking from the injection portion  191 . For this reason, in the hemostatic device  100 , when the patient moves the hand H in a state where the hemostatic device  100  is worn on the patient, the inflatable member  170  and the auxiliary member  180  compressing the puncture site t on the hand H are deformed. When there is no escape place for air in the lumen  171  of the inflatable member  170  and the lumen  181  of the auxiliary member  180  during deformation of the inflatable member  170  and the auxiliary member  180 , deformation of the inflatable member  170  and the auxiliary member  180  is hindered. For this reason, the patient&#39;s movement of the hand H is restricted. The cushioning member  192  included in the hemostatic device  100  allows air to move from the lumen  171  of the inflatable member  170  and the lumen  181  of the auxiliary member  180  to the cushioning member  192  when the patient moves the hand H. For this reason, it is possible to restrict the movable range of the patient&#39;s hand H by the inflatable member  170  and the auxiliary member  180 . When the patient returns the hand H from the deformed state to the original state, air moves from the cushioning member  192  to the inflatable member  170 . Therefore, the compressive force can be effectively applied to the puncture site t from the inflatable member  170 . 
     When the operator contracts the inflatable member  170  and the auxiliary member  180 , the operator inserts the distal tubular portion of the syringe into the injection portion  191  and pulls the plunger of the syringe. By performing the above operation, the operator can discharge the air in the inflatable member  170  and the air in the auxiliary member  180  to the syringe. 
     When the operator inflates the inflatable member  170 , the operator can visually confirm that the inflatable member  170  and the auxiliary member  180  can be pressurized without leakage of air by confirming expansion of the cushioning member  192 . 
     Next, usage examples of the hemostatic device  100  will be described with reference to  FIGS. 8 to 11 . In the following, a description will be given of an example of a procedure for attaching the hemostatic device  100  to the left hand H of the patient on which the puncture site t is formed. 
       FIG. 8  illustrates a state after performing various procedures by inserting the sheath tube of the introducer  200  into the distal radial artery side of the palmar artery B via the puncture site t (see  FIG. 11 ) formed on the dorsal side Hb of the hand H of the patient. In addition,  FIG. 8  illustrates a state in which a part of the sheath tube of the introducer  200  is pulled out from the puncture site t after completing the above procedures. 
     At the start of hemostasis, as illustrated in  FIG. 8 , the operator disposes the main body  120  of the covering member  110  so as to overlap the side of the dorsal side Hb of the hand H of the patient. In this instance, the marker portion  105  formed at a substantially center position of the inflatable member  170  is disposed at the puncture site t. 
     Subsequently, as illustrated in  FIG. 9 , the operator wraps the main body region  133  of the first arm portion  130  along an outer circumference of the hand H of the patient. The operator brings the third securing member  153  disposed on the inner surface of the first arm portion  130  into contact with the fourth securing member  154  disposed on the outer surface of the second arm portion  140  while wrapping the main body region  133  of the first arm portion  130  along the outer circumference of the hand H of the patient, thereby securing the first arm portion  130  and the second arm portion  140  via the respective securing members  153  and  154 . 
     Subsequently, as illustrated in  FIG. 10 , the operator folds a part of the first arm portion  130  not fixed to the second arm portion  140  back to the palm side of the hand H of the patient. In this instance, the operator can bring the first securing member  151  disposed on the outer surface of the first arm portion  130  into contact with the second securing member  152  disposed on the outer surface of the first arm portion  130 , so that a surplus part of the first arm portion  130  not wrapped around the hand H is secured via the respective securing members  151  and  152  in a folded state illustrated in  FIG. 10 . 
     Through the above procedure, as illustrated in  FIG. 10 , the operator can secure the hemostatic device  100  to the hand H of the patient.  FIG. 10  illustrates a state in which the introducer  200  is completely removed from the puncture site t. 
     Subsequently, the operator inflates the inflatable member  170  and the auxiliary member  180  by connecting a syringe to the injection portion  191  and injecting air into the inflatable member  170 . In the hemostatic device  100 , when the inflatable member  170  and the auxiliary member  180  are inflated, the inflatable member  170  applies a compressive force to the puncture site t. After inflating the inflatable member  170  and the auxiliary member  180 , the operator removes the sheath tube of the introducer  200  from the puncture site t as illustrated in  FIG. 10 . In this instance, since the first arm portion  130  and the second arm portion  140  are disposed along an outer peripheral direction of the hand H of the patient, the arm portions  130  and  140  do not overlap with the sheath tube of the introducer  200 . For this reason, after inflating the inflatable member  170  and the auxiliary member  180 , the operator can easily remove the sheath tube of the introducer  200  from the puncture site t. 
     The operator confirms that there is no bleeding from the puncture site t while hemostasis is performed using the hemostatic device  100 . When there is bleeding from the puncture site t, the operator adjusts the amount of air injected into the inflatable member  170  and the auxiliary member  180 . 
     As illustrated in  FIG. 11 , in a state where the hemostatic device  100  is worn on the hand H of the patient, a distal side part of the inflatable member  170  and the auxiliary member  180  are disposed on the fingertip side of the hand H. In addition, a proximal side part of the inflatable member  170  is disposed on the wrist side of the hand H. Since the proximal portion  174   b  of the inflatable member  170  is connected to the second end portion  122  of the main body  120  of the covering member  110 , an edge portion that may bite into the surface of the hand H of the patient is not formed in the proximal portion  174   b  of the inflatable member  170 . For this reason, it is possible to prevent the proximal portion  174   b  of the inflatable member  170  from coming into contact with the skin of the hand H of the patient. 
     Here,  FIG. 12  illustrates a state in which the hand H of the patient is bent toward the side of the dorsal side Hb of the hand H (i.e., the upper side in  FIG. 12 ) while the hemostatic device  100  is worn on the hand H of the patient. In the main body  120 , when the hand H of the patient is bent and the shape of the hand H is deformed during inflation of the inflatable member  170  while the hemostatic device  100  is worn on the hand H of the patient, the curved region  125  is deformed to be folded following a change in the shape of the hand H. When the curved region  125  is deformed to be folded, a part of the curved region  125  is disposed on the proximal side (i.e., the wrist side) of the proximal portion  174   b  of the inflatable member  170 . For this reason, when the patient wearing the hemostatic device  100  moves the hand H, it is possible to prevent the curved region  125  of the main body  120  from coming into contact with the surface of the hand H, and the proximal portion  174   b  of the inflatable member  170  from being strongly pressed against the surface of the hand H of the patient. 
     When the inflatable member  170  and the auxiliary member  180  are inflated, the auxiliary member  180  applies an oblique force toward the puncture site t side so as to compress the distal portion  174   a  side of the inflatable member  170 . For this reason, the hemostatic device  100  can effectively increase the compressive force applied to the puncture site t by the inflatable member  170 . 
     After a certain period of time passes after start of hemostasis, the operator gradually depressurizes the inflatable member  170  and the auxiliary member  180  to confirm that hemostasis at the puncture site t is properly performed. After the hemostasis at the puncture site t is completed, the operator sufficiently depressurizes the inflatable member  170  and the auxiliary member  180 . Then, the operator releases securing of the hemostatic device  100  by the first arm portion  130  and the second arm portion  140 , and removes the hemostatic device  100  from the hand H of the patient. 
     In the hemostatic device  100 , as illustrated in  FIG. 10 , during hemostasis, while the arm portions  130  and  140  are secured in a wrapped state along the outer circumference of the hand H of the patient, fingers of the patient can be allowed to project toward the distal side of the main body  120  of the covering member  110 . For this reason, since each finger is not covered by the covering member  110  in the state where the hemostatic device  100  is worn on the hand H, the patient can freely move the fingers while hemostasis is performed. 
     The operator can easily attach the hemostatic device  100  to the patient within a short time using the first arm portion  130  and the second arm portion  140  by proceeding with an attachment operation according to the procedure illustrated in  FIGS. 8 to 10 . Further, in the hemostatic device  100 , the covering member  110  can be secured to the hand H of the patient using the securing members  151 ,  152 ,  153 ,  154 , and  155  disposed on the respective arm portions  130  and  140 . For this reason, the hemostatic device  100  can reduce a burden on the skin of the patient during wearing when compared to a hemostatic device secured to the hand H or the forearm A of the patient using a seal member provided with an adhesive material, etc. 
     Further, since the hemostatic device  100  includes the inflatable member  170  that applies a compressive force to the puncture site t, the compressive force can be easily adjusted by adjusting the internal pressure of the inflatable member  170 . Further, in the hemostatic device  100 , even when the inflatable member  170  is deformed so as to change the internal pressure following movement of the hand H when the patient moves the hand H, the deformable auxiliary member  180  mitigates the change in the internal pressure of the inflatable member  170 . For this reason, the inflatable member  170  has a high following property to movement of the hand H of the patient, and compression on the puncture site t by the inflatable member  170  can be appropriately maintained. 
     Further, the hemostatic device  100  covers only a part of the hand H of the patient by the covering member  110 , and does not cover the entire hand H. For this reason, when the patient moves the hand H in the state where the hemostatic device  100  is worn on the hand H of the patient, it is possible to prevent movement of the hand H of the patient from being transmitted to the entire hemostatic device  100 . Therefore, the hemostatic device  100  can suppress misalignment from the hand H of the patient when the patient moves the hand H in the state where the hemostatic device  100  is worn on the hand H of the patient. 
     Hereinafter, effects of the above-described embodiments will be described. 
     The hemostatic device  100  includes the covering member  110  disposed to cover the puncture site t on the hand H of the patient, the plurality of securing members  151 ,  152 ,  153 ,  154 , and  155  for securing the covering member  110  in a state where the covering member  110  covers the puncture site t, the inflatable member  170  connected to the covering member  110  and inflated by injection of a fluid, and the auxiliary member  180  which has a smaller outer shape than that of the inflatable member  170  and is deformable. The covering member  110  includes the main body  120  to which the inflatable member  170  is connected, the first arm portion  130  protruding from the main body  120 , and the second arm portion  140  protruding from a position facing the first arm portion  130  with the main body  120  interposed therebetween. The main body  120  includes the first end portion  121  located on the distal side of the main body  120  between the first arm portion  130  and the second arm portion  140 , and the second end portion  122  located on the proximal side of the main body  120 . The inflatable member  170  is connected to the second end portion  122 , and the auxiliary member  180  is connected to the first end portion  121  in a state of being interposed between the main body  120  and the inflatable member  170 . 
     In the hemostatic device  100  configured as described above, since the auxiliary member  180  is connected to the first end portion  121  of the main body  120  located on the distal side of the inflatable member  170 , when the patient moves the hand H in the state where the inflatable member  170  is inflated, the proximal portion  174   b  of the inflatable member  170  located on the proximal side of the proximal portion  184   b  of the auxiliary member  180  easily comes into contact with the surface of the hand. However, in the hemostatic device  100 , since the inflatable member  170  is connected to the second end portion  122  of the main body  120  located on the proximal side of the inflatable member  170 , an edge portion that may bite into the surface of the hand H of the patient is not formed at the proximal portion  174   b  (i.e., the outer peripheral edge) of the inflatable member  170 . In this way, even when the patient moves the hand in the state where the inflatable member  170  is inflated, the hemostatic device  100  can prevent the proximal portion  174   b  (i.e., the outer peripheral edge) of the inflatable member  10  from biting into the hand, and thus it is possible to reduce the pain of the patient during hemostasis. 
     In addition, since the hemostatic device  100  includes the auxiliary member  180  that compresses the inflatable member  170  on the distal side of the inflatable member  170 , it is possible to ensure a large area in which the inflatable member  170  compresses the hand H of the patient on the distal side of the inflatable member  170 . For this reason, in the inflatable member  170 , even when the hemostatic device  100  moves to the wrist side due to movement of the finger of the patient, etc., it is possible to prevent the puncture site t from shifting from a range in which the inflatable member  170  applies the compressive force to the hand. 
     In addition, since the auxiliary member  180  compresses the inflatable member  170  on the distal portion  174   a  side of the inflatable member  170 , the hemostatic device  100  performs compression so that rising of the distal portion  174   a  of the inflatable member  170  is prevented and the distal portion  174   a  side of the inflatable member  170  comes into contact with the surface of the hand H in a large area. For this reason, when the auxiliary member  180  presses the inflatable member  170 , the hemostatic device  100  can ensure a large area in which the distal portion  174   a  side of the inflatable member  170  compresses the surface of the hand H while preventing rising of the inflatable member  170  and prevent the inflatable member  170  from shifting from the puncture site t. In addition, the auxiliary member  180  prevents misalignment of the inflatable member  170  with respect to the hand H by pressing a part of the inflatable member  170  against the hand H. 
     When hemostasis is performed at the puncture site t on the hand H, the hemostatic device  100  worn on the hand H does not shift to the distal side of the hand H due to the shape of the hand H since when the hand H is expanded, the shape of the hand H becomes wider toward the fingertip side. However, the hemostatic device  100  may shift to the proximal side of the hand H. In the hemostatic device  100 , the inflatable member  170  compresses a large area of the hand H located on the fingertip side of the puncture site t. For this reason, even when the hemostatic device  100  is shifted to the wrist side, the hemostatic device  100  can prevent the puncture site t from shifting from the range in which the inflatable member  170  applies a compressive force to the hand H. 
     In addition, in the hemostatic device  100 , the inflatable member  170  is connected to the main body  120  at a different position from that of the first arm portion  130  and the second arm portion  140  wrapped along the outer circumference of the hand H of the patient, and the first arm portion  130  and the second arm portion  140  are connected to positions facing each other with the main body  120  interposed therebetween. For this reason, in the hemostatic device  100 , when the hand H is moved while the hemostatic device  100  is worn on the hand H of the patient, the fluid located inside the inflatable member  170  easily moves along a longitudinal direction of the first arm portion  130  and the second arm portion  140  (i.e., the right-left direction of  FIG. 3 ). In this way, in the inflatable member  170 , since the end portion of the inflatable member  170  on the first arm portion  130  side and the end portion of the inflatable member  170  on the second arm portion  140  side are pressed against the surface of the hand of the patient by the main body  120  of the covering member  110 , it is possible to increase the compression area of the inflatable member  170  with respect to the puncture site t. 
     Further, in the hemostatic device  100 , the inflatable member  170  is connected to the first end portion  121  of the main body  120 , and the auxiliary member  180  is connected to the second end portion  122  of the main body  120  so as to face the inflatable member  170  with the main body  120  interposed therebetween. For this reason, the inflatable member  170  and the auxiliary member  180  have different connection positions with respect to the main body  120 , and thus easily follow movement of the hand H, etc. In addition, the inflatable member  170  is deformed with respect to a contact position between the inflatable member  170  and the auxiliary member  180  in a state where the hemostatic device  100  is worn and the inflatable member  170  is inflated, and thus is easily deformed following movement of the hand H. 
     Further, in the hemostatic device  100 , since the auxiliary member  180  having a smaller outer shape than that of the inflatable member  170  is disposed between the main body  120  and the inflatable member  170 , the auxiliary member  180  can adjust a compressive force applied to the hand H by a predetermined position of the inflatable member  170 . For this reason, the hemostatic device  100  can suitably apply the compressive force to the hand H by the predetermined position of the inflatable member  170 . 
     Further, the auxiliary member  180  is connected to the inflatable member  170  at a position biased toward one end side (i.e., the distal portion  174   a  side) of the inflatable member  170 . For this reason, the hemostatic device  100  can reliably prevent rising of the distal portion  174   a  side of the inflatable member  170  when the inflatable member  170  is inflated, and prevent misalignment between the inflatable member  170  and the auxiliary member  180  during inflation of the inflatable member  170 . 
     In addition, to apply an oblique force to compress the distal portion  174   a  side of the inflatable member  170 , the auxiliary member  180  covers the distal portion  174   a  side of the inflatable member  170 , and inhibits an inflation force of the inflatable member  170  from escaping to the outside of the main body  120 . 
     Furthermore, since the auxiliary member  180  for compressing the inflatable member  170  is provided on the distal portion  174   a  side of the inflatable member  170 , it is possible to ensure a large area in which the distal portion  174   a  side of the inflatable member  170  compresses the skin of the hand H of the patient. In this way, even in a state where the hemostatic device  100  is moved to the wrist side due to movement of the finger of the patient, it is possible to prevent the compression position of the inflatable member  170  with respect to the skin of the hand H from shifting from the puncture site t. 
     In addition, the auxiliary member  180  is an auxiliary inflatable portion inflatable by injection of a fluid, and the auxiliary inflatable portion is connected to the inflatable member  170  in a state of communicating with the inflatable member  170 . For this reason, when the hemostatic device  100  is worn, the auxiliary member  180  can be contracted, and thus it is possible to easily align the hemostatic device  100  with respect to the puncture site t. In addition, since the inflatable member  170  and the auxiliary member  180  communicate with each other, the inflatable member  170  and the auxiliary member  180  can be inflated at the same time by injecting a fluid into the inflatable member  170 , which can reduce the labor of the operator. 
     Further, the inflatable member  170  is connected to the center portion  184   c  of the auxiliary member  180 . For this reason, in the hemostatic device  100 , even in the state where the inflatable member  170  is inflated, the inflatable member  170  can be flexibly deformed along a connection portion with the auxiliary member  180 . In this way, when the hand H of patient moves, the inflatable member  170  can follow the change in the shape of the hand H, and appropriately maintain the compressive force on the puncture site t on the hand H of the patient. 
     In addition, the main body  120  is connected to the proximal portion  174   b  of the inflatable member  170  (i.e., the peripheral edge located at the end portion of the inflatable member  170  on the proximal side) and the distal portion  184   a  of the auxiliary member  180  (i.e., the peripheral edge located at the end portion of the auxiliary member  180  on the distal side). For this reason, in the hemostatic device  100 , steps are formed at a connection position between the main body  120  and the proximal portion  174   b  of the inflatable member  170  and a connection position between the main body  120  and the distal portion  184   a  of the auxiliary member  180 . However, an edge portion that may bite into the surface of the hand H of the patient is not formed at the proximal portion  174   b  (i.e., the outer peripheral edge) of the inflatable member  170  and the distal portion  184   a  (i.e., the outer peripheral edge) of the auxiliary member  180 . In this way, when the patient moves the hand H, in the state where the inflatable member  170  is inflated, the hemostatic device  100  can prevent an edge of the peripheral edge of the inflatable member  170  and an edge of the peripheral edge of the auxiliary member  180  from coming into contact with the skin of the hand H of the patient and causing pain due to biting, etc. In addition, in the hemostatic device  100 , since the main body  120  is connected to the proximal portion  174   b  of the inflatable member  170  and the distal portion  184   a  of the auxiliary member  180 , the inflatable member  170  and the auxiliary member  180  are located on the internal surface side of the main body  120  in the state where the inflatable member  170  is inflated. For this reason, the hemostatic device  100  can suitably transmit the compressive force of the inflatable member  170  to the puncture site t. 
     Further, the main body  120  has the curved region  125  on the second end portion  122  side, and the inflatable member  170  is connected to the curved region  125 . Since the curved region  125  is formed in the main body  120 , the space  124  can be formed between the main body  120  and the inflatable member  170 . By having the space  124 , the main body  120  is deformed so that the curved region  125  is folded when the inflatable member  170  is inflated, and the second end portion  122  of the main body  120  is curved toward the first end portion  121  side of the main body  120 . For this reason, when the inflatable member  170  is inflated, it is possible to more reliably prevent the second end portion  122  of the main body  120  from biting into the skin of the hand H of the patient. 
     Further, in the first arm portion  130 , the wall thickness of the peripheral edge  130   a  of the first arm portion  130  on the proximal side is smaller than the wall thickness of the center portion  130   b  of the first arm portion  130 . In the second arm portion  140 , the wall thickness of the peripheral edge  140   a  of the second arm portion  140  on the proximal side is smaller than that of the center portion  140   b  of the second arm portion  140 . For this reason, in the hemostatic device  100 , the wall thicknesses of the peripheral edges  130   a  and  140   a  located on the wrist side of the respective arm portions  130  and  140 , which serve as start points of movement of the finger when the patient moves the finger in the state where the hemostatic device  100  is worn on the hand H of the patient, are small. In this way, the hemostatic device  100  can prevent the peripheral edges  130   a  and  140   a  of the respective arm portions  130  and  140  from biting into the skin of the hand H when the patient moves the hand H. 
     Further, the first arm portion  130  is longer than the second arm portion  140 . For this reason, in the hemostatic device  100 , when the hemostatic device  100  is worn on the hand H of the patient, securing positions of the first arm portion  130  and the second arm portion  140  are located on the palm side of the hand H or the side of the dorsal side Hb of the hand H, and thus the inflatable member  170  can be more reliably secured to the hand H of the patient by the first arm portion  130  and the second arm portion  140 . 
     Next, a description will be given of Modification Example 1 and Modification Example 2 of the hemostatic device according to the above-described embodiments. In the description of each of the modification examples, detailed description of a configuration, etc. previously described in the embodiments will be omitted. Further, content not particularly described in the description of the modification examples can be regarded as similar content to that of the embodiments. 
       FIG. 14  illustrates a hemostatic device  100 A according to Modification Example 1. The hemostatic device  100 A according to Modification Example 1 includes a third arm portion  300  protruding from the main body  120  of the covering member  110  at a different position from that of the first arm portion  130  and the second arm portion  140 . Specifically, the third arm portion  300  protrudes from the first end portion  121  side of the main body  120  of the covering member  110 . 
     As illustrated in  FIG. 15 , the third arm portion  300  can be disposed between or at an inter-finger portion of adjacent fingers f 1  and f 2  of the hand H of the patient in a state where the hemostatic device  100 A is worn on the hand H of the patient. The third arm portion  300  is formed of a flexible member that can be deformed along the shape of the outer surface of the hand H of the patient. Even though the third arm portion  300  can be disposed in an inter-finger portion between the thumb f 1  and the index finger f 2  in the hemostatic device  100 A, the third arm portion  300  may be disposed in an inter-finger portion located between other fingers. 
     The third arm portion  300  includes a securing member  350  that can be connected to the first arm portion  130  on the inner surface side of the third arm portion  300 . The securing member  350  of the third arm portion  300  can be connected to the second securing member  152  of the first arm portion  130 . For this reason, the third arm portion  300  can be secured to the first arm portion  130  by bringing the securing member  350  disposed on the inner surface side of the third arm portion  300  into contact with the second securing member  152  of the first arm portion  130 . Therefore, as illustrated in  FIG. 15 , after securing the first arm portion  130  and the second arm portion  140  via the respective securing members  152  and  154  while wrapping the first arm portion  130  along the outer circumference of the hand H of the patient, the operator passes the third arm portion  300  between the thumb f 1  and the index finger f 2  of the hand H of the patient, and superimposes a part of the third arm portion  300  on the palm side of the hand H of the patient on the first arm portion  130  wrapped along the outer circumference of the hand H of the patient. In this way, by bringing the securing member  350  disposed on the inner surface side of the third arm portion  300  into contact with the second securing member  152  of the first arm portion  130 , the operator can secure the first arm portion  130  and the third arm portion  300  via the securing member  152  and the securing member  350  of the third arm portion  300 . According to such a configuration, by securing the third arm portion  300  to the first arm portion  130  through between the fingers f 1  and f 2  of the patient, the hemostatic device  100 A can effectively prevent the inflatable member  170  from rising on the distal side of the hand H while effectively preventing misalignment of the inflatable member  170  with respect to the puncture site t. For this reason, even when the hand H is moved in the state where the inflatable member  170  is inflated, by securing the first arm portion  130  and the second arm portion  140  and securing the third arm portion  300  and the first arm portion  130 , the hemostatic device  100 A can effectively prevent rising of the distal side of the main body  120  to which the inflatable member  170  is connected, and appropriately maintain the compressive force of the inflatable member  170  on the puncture site t of the hand H. 
     The securing member  350  of the third arm portion  300  is formed of the male side of the surface fastener. The surface fastener is a fastener that is removable in terms of surface, and is, for example, MAGIC TAPE® or VELCRO®. 
     A configuration of the securing member  350  of the third arm portion  300  is not limited as long as the securing member  350  can be secured to the first arm portion  130  wrapped around the limb of the patient. For example, a position where the securing member  350  is disposed on the third arm portion  300  can be changed as appropriate. Further, when the securing members  151 ,  152 ,  153 ,  154 , and  155  and the securing member  350  of the third arm portion  300  include surface fasteners, the male side and the female side of the surface fasteners may be interchanged. Further, the securing members  151 ,  152 ,  153 ,  154 , and  155  and the securing member of the third arm portion  300  may be snaps, buttons, clips, frame members in which holes are formed, etc. 
     In the hemostatic device  100 A according to Modification Example 1, the covering member  110  is formed by the main body  120  and the arm portions  130 ,  140 , and  300  as separate members. The main body  120  and the third arm portion  300  can be connected by, for example, adhesion, welding, etc. However, in the hemostatic device  100 A, any part of the main body  120 , the first arm portion  130 , the second arm portion  140 , and the third arm portion  300  of the covering member  110  may be integrally formed of one member. 
       FIGS. 16 and 17  illustrate a hemostatic device  100 B according to Modification Example 2. In the hemostatic device  100 B according to Modification Example 2, the third arm portion  300  is detachable from and connectable to the main body  120  of the covering member  110 .  FIG. 16  illustrates a state before the third arm portion  300  is connected to the main body  120  of the covering member  110 , and  FIG. 17  illustrates a state in which the third arm portion  300  is connected to the main body  120  of the covering member  110 . 
     The third arm portion  300  includes a main body  310  and a connection portion  320  disposed on one end side of the main body  310 . The main body  310  of the third arm portion  300  includes a securing member  350  connectable to the first arm portion  130  on the inner surface side of the third arm portion  300 . For this reason, the securing member  350  of the main body  310  can be connected to the second securing member  152  of the first arm portion  130 . Further, the connection portion  320  of the third arm portion  300  can be connected to the first end portion  121  side of the main body  120  of the covering member  110 . For example, the connection portion  320  of the third arm portion  300  is attachable to the main body  120  of the covering member  110  by an adhesive material, a bonding material, etc. on the inner surface side or the outer surface side of the connection portion  320 . 
     In addition, the connection portion  320  of the third arm portion  300  may be attachable to the main body  120  of the covering member  110  by the male side of the surface fastener disposed on the inner surface side of the connection portion  320  and the female side of the surface fastener disposed on the outer surface side of the first end portion  121  side of the main body  120  of the covering member  110  so that the inner surface side of the connection portion  320  is connected to the outer surface side of the main body  120 . In this way, in the hemostatic device  100 B, since the third arm portion  300  can be attached to the main body  120  of the covering member  110  at the discretion of the operator, the operator can provide the third arm portion  300  on the hemostatic device  100 B according to the condition of the hand H of the patient (for example, the hand H is easily sweated). 
     A material used for the third arm portion  300  of the covering member  110  of each of the hemostatic device  100 A and the hemostatic device  100 B is not particularly limited. For example, the same material as that exemplified as the first arm portion  130  and the second arm portion  140  of the covering member  110  can be mentioned. 
     Even though the hemostatic devices  100 ,  100 A,  100 B, and  100 C have been described, the invention is not limited to the embodiments described in this specification, and can be appropriately modified based on description of the scope of claims. 
     In the description of the embodiments, the hemostatic device for performing hemostasis at the puncture site formed on the dorsal side of the left hand has been exemplified. However, the hemostatic device can be used to perform hemostasis on a puncture site formed on a dorsal side of a right hand, a puncture site formed on a palm of the right hand, a puncture site formed on a palm of the left hand, etc. 
     The auxiliary member is not limited to the inflatable member described in each embodiment. For example, the auxiliary member may include a member made of a resin material such as plastic, gel, etc., a member containing gel whose moisture content decreases over time to gradually reduce a compressive force, an elastic material such as a sponge-like substance, an aggregate of fibers such as cotton, metal, a member having a predetermined three-dimensional shape (sphere, ellipsoid, triangular pyramid, etc.), an appropriate combination thereof, etc. 
     In addition, the shape, dimensions, etc. of each portion of the hemostatic device are not particularly limited and can be changed as appropriate as long as the inflatable member can be disposed at the site where bleeding is to be stopped while wrapping the first arm portion and the second arm portion around at least a part of the limb including the hand.
