A cuff for a blood pressure information measurement device, wherein the cuff is attached in use at a measurement site for measuring blood pressure information and wherein the cuff comprises
a fluid bag (20) for compressing the measuring point;
an elastic plate (24) that is flexible and curved and located outside of the fluid bladder (20) while the fluid bladder (20) is wrapped around the measurement site and is annular or arcuate to extend along the measurement site;
an inflation and deflation means which is attached to the curved elastic plate (24) and inflates and deflates the fluid bag (20); and
a bag-shaped cowling body (12) encapsulating the fluid bag (20), the inflating and deflating means and the curved elastic plate (24).
The present invention relates to a cuff for a device for measuring blood pressure information, which is attached to a measurement site in use, and a blood pressure information measurement device equipped with the cuff.
It is very important to obtain information about the blood pressure of a patient in order to recognize the health status of the patient. Recently, not only the systolic blood pressure value, the diastolic blood pressure value and the like, which have been generally recognized as representative health care indices, but also the pulse wave of the patient in an attempt to identify, for example, a change in cardiac load and hardness of the artery, measured. A blood pressure information measuring apparatus is a device for obtaining these health care indices based on obtained information on the blood pressure, and is expected to be used in fields such as early detection, prevention, treatment and the like of circulatory system diseases. The aforementioned blood pressure information contains a wide variety of information about the circulatory system, such as the systolic blood pressure value, the diastolic blood pressure value, the average blood pressure value, the pulse wave, the pulse rate, and the AI (amputation index).
The blood pressure information is generally measured with a cuff for a blood pressure information measuring apparatus having a fluid bag therein (hereinafter simply referred to as a cuff). Here, a sleeve refers to a band-like structure having an internal cavity and can be wound around a part of a living body, and a fluid, such as a gas or a liquid, is injected into the internal cavity such that the fluid bag for use in the measurement the blood pressure information is inflated and deflated. With respect to a blood pressure information measuring device (hereinafter also referred to simply as a blood pressure monitor) for measuring blood pressure values such as the systolic blood pressure value and diastolic blood pressure value, for example, a cuff is wrapped with a fluid bag in the same for compressing the artery around a surface of a living body, the fluid bag wound around the same is inflated and deflated to obtain the pressure pulse wave of the artery as a change of the internal pressure of the fluid bladder and thereby measure the blood pressure value. In particular, a cuff of the type which is wound around an arm in use is called an arm belt or cuff.
To measure blood pressure information, usually an upper arm or wrist is used as the measuring point. The cuff is therefore wrapped around an upper arm or wrist when in use. The above-described blood pressure monitors are classified by the difference in the measurement site into an upper arm blood pressure monitor and a wrist blood pressure monitor.
For the wrist blood pressure monitor, a structure in which the cuff and a main body are integrated is generally used. More specifically, on the outer peripheral surface of the sleeve, which has in the same an air bag as a fluid bag, a housing attached, which serves as a main body. The housing accommodates various types of components, such as inflation and deflation means for inflating and deflating the air bag (generally a pressurizing pump, an outlet valve, and the like). This is because the circumferential length of the wrist to be used as a measurement site is shorter than that of the upper arm and the artery to be compressed is at a relatively superficial position from the body surface, and therefore, the airbag may have a small capacity and consequently, the inflation and deflation means are used with a relatively small capacity and small size, and the components can be accommodated in the housing with a small size.
In contrast, with respect to the upper arm blood pressure monitor, since the circumferential length of the upper arm to be used as a measurement site is longer than that of the wrist and the artery to be compressed is at a relatively low position from the body surface, that the airbag has a large capacity, and hence the high-performance and large-size inflating and deflating device is required. With respect to the upper arm blood pressure monitor, therefore, the cuff and the main body are generally not integrated, but provided as separate and independent components.
However, some upper arm blood pressure monitors are configured such that the cuff and main body are integrated. Such a blood pressure monitor having the integrated cuff and the integrated main body is provided so used be that the main body is mounted on a table or the like, and has a structure in which the main body is provided with various types of components, such as the inflation and deflation means, the main body has a hollow opening which is formed to allow a metering point to be inserted into the opening, and the collar containing the airbag is provided to extend along the hollow opening of the main body. With regard to the blood pressure monitor configured in the above-described manner, the main body must be mounted in use on a mounting surface such as a table, and therefore, such a blood pressure monitor can be used only in a limited use environment and is not necessarily excellent in application comfort ,
Meanwhile, various types of components such as the above-described inflator and defogger have been remarkably downsized recently, and components having a high performance and a small size have become established. Therefore, even in the upper arm blood pressure monitoring device, such high-power and small-sized components can be used to considerably downsize the main body as compared with the conventional main body. Consequently, for an upper arm blood pressure monitor which is also provided to have a cuff and a main body separately from each other, a structure becomes possible in which various types of components such as the inflation and deflation means are housed in a housing of a small size are and the housing is integrated with the cuff.
Some documents note such a reduction of various types of components and disclose a blood pressure monitor which deals with the integration of a small main body with a cuff. Such documents contain, for example, the Japanese Patent Laid-Open Publication No. 3-85138 (Patent Document 1), the Japanese Patent Laid-Open Publication No. 2000-83912 (Patent Document 2), and the Japanese Laid-Open Publication No. 7-163531 (Patent Document 3).
A blood pressure monitor, which in the above Japanese Patent Laid-Open Publication No. 3-85138 is configured such that a collar and a main body are separately formed, various types of components such as an inflation and deflation means are housed in the main body, and the main body can be detachably mounted at any position on the outer peripheral surface of the collar , A blood pressure monitor, which in the above Japanese Patent Laid-Open Publication No. 2000-83912 is configured such that a cuff and a main body are formed separately, the main body can be detachably attached to a base portion provided on the outer peripheral surface of the cuff, various types of components such as an inflation and deflation device, are provided on the base portion and only a display portion and an operating portion are provided on the main body. In addition, a blood pressure monitoring device, which in the above Japanese Laid-Open Publication No. 7-163531 is configured such that an opening is formed at a predetermined position of the outer peripheral surface of a bag-like casing body extending over the surface of the cuff, a part of a casing which is a main body is embedded inside the bag-like casing body Close the opening, and various types of components, such as an inflation and deflation, are housed in the partially embedded housing.
These blood pressure monitors, which in the Japanese Patent Laid-Open Publication No. 3-85138 . 2000-83912 and 7-163531 are each configured such that the monitoring device can make a measurement without the main body on a mounting surface, such as a table, must be attached, and consequently, the blood pressure monitoring devices have a small size, which is suitable for entrainment.
Patent document 1: Japanese Patent Laid-Open Publication No. 3-85138
Patent document 2: Japanese Patent Laid-Open Publication No. 2000-83912
Patent 3: Japanese Laid-Open Publication No. 7-163531
When the structure is used, which in the above Japanese Patent Laid-Open Publication No. 3-85138 However, problems arise such as a problem that an air hose connecting the cuff and the main body makes the measurement difficult, and a problem in storage that the handling of the air tube is cumbersome. When the structure is used, which in the above Japanese Patent Laid-Open Publication No. 2000-83912 is disclosed, there arises a problem that the base portion is inevitably thick, the convenience of use is not good, and hence the blood pressure monitor is not suitable for entrainment. When employing the structure disclosed in the above Japanese Unexamined Patent Publication Nos. 2000-83912 and 7-163531 a problem may arise that the portion of the sleeve on which the main body is provided, during the attachment of the sleeve at a measuring point (here, the main body in the Japanese Patent Application Laid-open No. 2000-83912, the base portion and in the Japanese Offenlegungsschrift 7-163531 the housing) not flexibly deformed, the cuff does not lie well at the measuring point, so that a gap between the measuring point and the cuff is generated, and the accuracy of the measurement of the blood pressure value is reduced.
Also, in the case where the wrist blood pressure monitor is configured such that the housing is attached to the outer peripheral surface of the cuff which is conventionally used, as in the above Japanese Patent Laid-Open Publication No. 2000-83912 Still, the structure disclosed a problem in that the housing is inevitably thick, the convenience of use is not good, and hence the blood pressure monitor is not suitable for entrainment.
Therefore, the present invention has been made to solve the above-described problems, and an object of the invention is a blood pressure information measuring apparatus which can be downsized and has excellent handling and portability, and a cuff for the blood pressure information measuring apparatus connected to the cuff to be supplied.

Then the CPU issues 130 a drive command to the CPU 30 through the communication units 132 . 32 and hence the CPU 30 with electrical power from the battery 50 supplied as a power source. The CPU 30 is thus powered and the blood pressure monitor 1 initialized as in 6 shown (step S101).
Next the CPU waits 30 to a command from the patient to begin the measurement. If the patient by pressing the operating section 190 The command to start the measurement causes the CPU 30 that the exhaust valve 42 is closed, and starts the pressurizing pump 41 to thereby drive the cuff pressure of the airbag 20 gradually increase (step S102). In the course of gradually increasing the pressure of the airbag 20 holds the CPU 30 when the cuff pressure reaches a predetermined level for measuring the blood pressure value, the pressurizing pump 41 and opens the exhaust valve 42 gradually, which was closed to thereby air from the airbag 20 gradually draining and gradually reducing the cuff pressure (step S103). The blood pressure monitor 1 according to the present embodiment measures the blood pressure value in this course, in which the cuff pressure is gradually reduced at an ultralong rate.
Next, the CPU calculates 30 Blood pressure values, such as the systolic and diastolic pressure values, following a known procedure (step S104). Especially in the course in which the cuff pressure of the airbag 20 is gradually reduced, the CPU wins 30 based on the resonant circuit 47 obtained oscillation frequency information about a pulse wave. Then, the blood pressure value is calculated from the obtained information about the pulse wave. The blood pressure value is calculated in step S104 and the CPU 30 supplies the CPU 130 with the blood pressure value as a result of the measurement by the communication units 32 . 132 , Based on this, the CPU causes 130 that the blood pressure reading on the display section 160 is displayed (step S105).
After that, the CPU opens 30 the airbag 20 to get the air in the airbag 20 completely draining (step S106), waiting for a patient's command to turn off the power, and terminating the operation. The measuring method described above is based on the so-called measuring method with a reduced pressure, by which the pulse wave is detected during the pressure of the airbag 20 is reduced. It will be obvious that it is also possible to use the so-called measuring method with an increased pressure, by means of which the pulse wave is detected during the pressure of the airbag 20 is increased.
At the blood pressure monitor 1 the present embodiment, the above has been described, are the pressurizing pump 41 and the exhaust valve 42 , which serve as inflation and deflation devices, inside the outer lining 12 accommodated. Regarding the pressurizing pump 41 and the exhaust valve 42 For example, these components have lately been reduced to a remarkable extent, the reduction in the strength of the profile of the components has become possible, and therefore may be the same as the blood pressure monitor 1 according to the present embodiment in the outer lining 12 be housed. Even if the structure such as that of the present embodiment is used, the sleeve unit is 10 consequently, not exceedingly thick, and hence the sufficiently good handling is maintained. When the structure described above is used, in which the air hose is not out of the sleeve unit 10 The blood pressure monitor may be provided with excellent handling and portability as well as storage and the cuff for the blood pressure monitor to be fitted with the cuff. Because the air hose is not from the cuff unit 10 In particular, the handling of a blood pressure monitor intended for long-term use, such as the night blood pressure monitor for measuring the blood pressure value while the patient sleeps, is improved. The above-described elevated pressure measurement method gradually detects the pulse wave in the airbag during air 20 is supplied and therefore requires a lower air capacity than the measuring method with a reduced pressure. If the measuring method with an increased pressure is used for the structure described above, the cuff unit can 20 also reduced in size and reduced in strength.
At the blood pressure monitor 1 In addition, in the present embodiment, the circuit board 38 on which the pressure sensor 43 is mounted, as well as the battery 50 , which serves as a power supply, also in the outer lining 12 accommodated. These components can also be downsized and reduced in thickness and the sleeve unit 10 in which they are housed, also maintains excellent handling. Thus, when the blood pressure monitor is configured in this manner, the associated unit which is from the cuff unit may 10 is configured separately, a compact and lightweight display unit 100 which, for example, with the display section 160 and the operation section 190 is provided. Consequently, the measurement can be made while the display unit 100 as in 5 is shown, the display unit 100 be operated in the position in which the patient can easily operate the same, and the handling is considerably improved. In addition, the blood pressure monitoring device 1 the present embodiment, the sleeve unit 10 and display unit 100 intended for communication by radio and therefore are the cuff unit 10 and display unit 100 not connected by an electric cable or the like, and the handling, portability and storage are not degraded.
In addition, the blood pressure monitoring device 1 In the present embodiment, each component of the plurality of components described above is individually attached to the flexible curler 24 fastened so that the deformation of the retractor 24 is not easily affected, and the retractor 24 is adequately attached to the upper arm while the cuff unit 10 is attached to the upper arm. Therefore, a gap between the sleeve unit 10 and prevents the upper arm and the blood pressure can be measured with high accuracy without reducing the attachment. At a portion which is located between the components, which along the circumferential direction of the retractor 24 can be provided and fixed, a slot or a portion with a reduced thickness, which extends in the axial direction, be provided or a rotating device may be provided to allow the retractor 24 is securely attached to the upper arm while the cuff unit 10 attached to the upper arm. Therefore, this structure can also ensure that a reduction of the attachment is prevented.
As described so far, the blood pressure monitor, which can be downsized and has excellent handling and portability, as well as the cuff for the blood pressure monitor to be equipped with the cuff, when the blood pressure monitor 1 and cuff unit 10 with which the blood pressure monitoring device is equipped are configured in the manner as in the present embodiment.

The structure of the blood pressure monitor and the cuff for the cuff-equipped blood pressure monitor according to the third embodiment of the present invention will be described with reference to FIGS 10 to 14 to be discribed. Components which are similar to the respective components of the blood pressure monitor and the cuff for the blood pressure monitor to be fitted with the cuff according to the first embodiment will be denoted by the same reference numerals in the drawings and the description thereof will not be repeated here.
The blood pressure monitoring device according to the present embodiment is configured such that a tightening operation of the cuff unit on an upper arm, an operation for measuring the blood pressure value performed after the tightening operation, and an operation for releasing the tightening of the cuff unit on the upper arm are performed after the measuring operation will be executed automatically one after the other.
As in the 10 to 13 shown, the blood pressure monitor differs 1 according to the present embodiment in the structure of the blood pressure monitoring device 1 and cuff unit 10 according to the first embodiment described above. The cuff unit 10 according to the present embodiment includes a tubular sleeve body 11 which is to be attached to an upper arm, and a handle portion 60 , which on the outer peripheral surface of the sleeve body 11 is provided. The grip section 60 contains a base 61 , which on the cuff body 11 attached, and a handle 62 which is to be gripped with one hand when the collar unit is to be fastened. The cuff body 11 is tubular to allow the upper arm to be inserted along the axial direction. The grip section 60 is so on the cuff body 11 attached that handle 62 parallel to the axial direction of the tubular sleeve body 11 extends. A tightening length adjusting device 80 , which will be described later, is located on the outer peripheral surface of the sleeve body 11 and in the base 61 of the grip section 60 , At a predetermined position of the handle portion 60 is a push button 64 intended.
As in the 10 and 12 shown, contains the cuff body 11 primarily tightening straps in a ring shape 14 and 15 , an outer lining 12 , which are on the inside of the tightening belt 14 attached, and a curling device 24 and an airbag 20 which in the outer lining 12 are housed. The tightening straps 14 . 15 are each formed of an element, such as a fabric having substantially no peripheral stretchability, and include a first tightening belt 14 with a relatively large width and a second tightening belt 15 with a relatively small width, which with the first tightening belt 14 connected is.
The first tightening belt 14 is made of a belt-like element with one end 14a and the other end 14b formed with respect to the circumferential direction, the handle portion described above 60 is mounted at a predetermined position on the outer peripheral surface of the first tightening belt and the outer cover described above 12 is mounted on the inner peripheral surface thereof. The second tightening belt 15 has an end 15a and the other end 15b with respect to the circumferential direction and one end 15a is with the other end 14b of the first tightening belt 14 connected. The second tightening belt 15 has a section which is relatively closer to the other end 15b is located on the outer periphery of a portion which is relatively closer to one end 14a of the first tightening belt 14 located, and the other end 15b the second tightening belt 15 is on a reel spool 88 attached, which in the handle portion 60 is arranged, which on the outer peripheral surface of the first tightening belt 14 is appropriate. Consequently, the first tightening belt work 14 and second tightening belt 15 as a unified and annularly configured element and thereby form the cuff body 11 with a hollow opening.
The connected first tightening belt 14 and second tightening belt 15 have the circumferential length defined by the tightening length adjuster 80 is set differently, which will be described later. Although the circumferential length of the connected first tightening belt 14 and second tightening belt 15 set to be long, but the cuff body 11 has a state with an enlarged diameter (the state in which the diameter is increased). Although the circumferential length thereof is set to be short, but the sleeve body 11 has a state of reduced diameter (the state in which the diameter is reduced).
The outer lining 12 is formed of an element, such as a fabric, which z. B. consists of a stretchable material with a low friction, and on the inner peripheral surface of the first tightening belt described above 14 appropriate. In particular, the outer peripheral surface of the outer lining 12 by gluing, welding or the like with the inner peripheral surface of the first tightening belt 14 connected and therefore is the outer lining 12 on the first tightening belt 14 attached.
The in the outer lining 12 encapsulated curling device 24 is arcuate and provided to be elastically deformable in the radial direction. As in 13 shown here are in the cuff unit 10 the present embodiment, the circuit board 38 on which the pressurizing pump 41 and the exhaust valve 42 (please refer 11 ), an air connector (not shown) and a pressure sensor 43 are mounted, and z. B. the battery 50 on the outer peripheral surface of the curler 24 arranged. That is, these various types of components are in the space in the outer panel 12 accommodated.
The curler 24 In the above-described state with an enlarged diameter assumes a state in which the diameter of the curler is increased to be larger. In contrast, the retractor takes 24 in the state described above with a reduced diameter, a state in which the diameter of the curler is reduced to be smaller. When the cuff body 11 assumes the state with an enlarged diameter, causes the spring force of the curler 24 in that the cuff body 11 increasing the insertion and removal of an upper arm into the hollow opening of the cuff body 11 and relieved from it.
As in 11 shown, contains the cuff unit 10 in addition to the functional blocks included in the sleeve unit of the first embodiment described above, a push button 64 , a geared motor 81 , an electromagnetic brake 82 , a spool roller 88 , a motor drive circuit 48 and a drive circuit 49 the electromagnetic brake. The geared motor 81 , the electromagnetic brake 82 and the spool roller 88 correspond to the tightening length setting means 80 showing the tightening length of the tightening straps 14 . 15 as described above, sets differently relative to an upper arm. At the blood pressure monitor 1 In the present embodiment, the airbag 20 and the air system component 40 as a firm force detecting means for detecting the tightening force of the tightening straps 14 . 15 used on the upper arm, and details thereof will be described later.
The geared motor 81 is an electric motor, which the coil role 88 in a forward and reverse rotational direction, and the operation of the motor is performed by the motor drive circuit 48 controlled. The electromagnetic brake 82 is a brake which applies a braking force to the spool roller 88 applies, and the operation of the brake is by the drive circuit 49 controlled by the electromagnetic brake. The spool roller 88 is an element for winding and feeding the tightening straps described above 14 . 15 , The push button 64 is a section which instructs a patient to start the tightening operation of the tightening length setting device 80 which comes from the geared motor 81 , the electromagnetic brake 82 and the spool roller 88 consists.
The motor drive circuit 48 controls the operation of the geared motor 81 based on a control signal supplied by the CPU 30 is entered. The drive circuit 49 the electromagnetic brake controls the operation of the electromagnetic brake 82 based on a control signal supplied by the CPU 30 is entered. At the blood pressure monitor 1 In the present embodiment, the one in the sleeve unit controls 10 provided CPU 30 driving the pressurizing pump 41 and the exhaust valve 42 and also driving the geared motor described above 81 and the electromagnetic brake 82 , and those in the cuff unit 10 provided battery 50 applies an electrical power to drive to the geared motor 81 and the electromagnetic brake 82 at.
As in the 12 to 14 shown contains the tightening length adjustment means 80 the geared motor 81 , the electromagnetic brake 82 and spool roller 88 , The geared motor 81 , the electromagnetic brake 82 and the spool roller 88 are on a support frame 66 provided at a position on the outer peripheral surface of the sleeve body 11 and in the base 61 of the grip section 60 is arranged. The carrier frame 66 is, for example, on the outer peripheral surface of the first tightening belt 14 attached. At corresponding, predetermined positions of the support frame 66 are gears 85 . 86 . 87 , which serve for power transmission, provided on the support frame.
The geared motor 81 is a provided with a reducer engine and includes a motor section 81a , a reducer section 81b and an output shaft 81c , At the output shaft 81c the geared motor 81 is the gear 85 attached. At the axis end opposite the side on which the output shaft 81c the geared motor 81 is the electromagnetic brake 82 adjacent to this geared motor 81 arranged. The electromagnetic brake 82 applies a braking force to a rotating shaft 81a1 by blocking the rotary shaft 81a1 of the engine section 81a out.
The spool roller 88 is on a wave 87a fixed on the support frame 66 is carried axially, and is rotated to the rotation of the shaft 87a to follow. At the spool roller 88 is the other end 15b the second tightening belt 15 attached as described above. At the wave 87a , on which the coil roller 88 attached is the gear 87 attached. At the wave 86a which are on the support frame 88 is worn axially, is the gear 86 attached. The gear 86 takes each of these gears 85 and 87 engaged on the output shaft 81c the geared motor 81 generated torque to the coil roller 88 transferred to. These gears 85 . 86 . 87 are configured with corresponding outer diameters and corresponding numbers of teeth which are set and operate like the reducer section 81b the geared motor 81 also as a reducer.
Next will be in terms of 14 the operation of the tightening length adjusting device 80 , which in the cuff unit 10 provided in the present embodiment. At the blood pressure monitor 1 In the present embodiment, as described above, the tightening operation of the cuff unit becomes 10 on an upper arm, the operation for measuring the blood pressure value, which is performed after the tightening operation, and the operation for releasing the tightening of the cuff unit 10 on the upper arm, which is performed after the measuring operation, automatically executed sequentially. From these operations, the tightening operation of the sleeve unit is performed 10 on the upper arm and the operation to release the tightening of the sleeve unit 10 on the upper arm in each case by a Aufwickelbetätigung the tightening straps 14 . 15 through the tightening length adjustment device 80 caused and a Zuführbetätigung the tightening straps 14 . 15 through the tightening length adjustment device 80 are each described below.
In relation to 14 the output shaft rotates 81c the geared motor 81 in the forward direction, the torque is transmitted through the gears 85 . 86 . 87 to the wave 87a transferred and the coil role 88 rotates in forward direction when the geared motor 81 is driven to turn in the forward direction. The forward rotation of the spool roller 88 that causes the second tightening belt 15 whose other end 15b on the spool roller 88 is secured by the spool roller 88 is wound in the direction indicated by an arrow A in 14 is displayed. The winding operation of the second tightening belt 14 passing through the spool roller 88 done, that causes the tightening length of the tightening straps 14 . 15 depending on the spring force of the curler 24 is reduced, and the diameter of the hollow opening of the sleeve body 11 is gradually reduced. That is, the take-up operation implements the tightening operation of the cuff unit 10 on an upper arm. Although the geared motor 81 driven to turn in the forward direction, but the electromagnetic brake 82 does not block the rotary shaft 81a1 of the engine section 81a the geared motor 81 and the engine section 81a is driven without being restricted in the operation thereof.
In contrast, the output shaft rotates 81c the geared motor 81 in the reverse direction, the torque is transmitted through the gears 85 . 86 . 87 to the wave 87a transferred and the coil role 88 turns in reverse direction when the geared motor 81 is driven to rotate in the reverse direction. The rotation of the spool roller 88 in the reverse direction causes the second tightening belt 15 which is around the spool roller 88 was wound from the bobbin 88 in the direction indicated by an arrow B in FIG 14 is displayed. The feeding operation of the second tightening belt 15 passing through the spool roller 88 takes place, lengthens the tightening length of the tightening straps 14 . 15 , At this time, the diameter of the hollow opening of the cuff body becomes 11 based on the spring force of the curler 24 gradually increased. That is, the feed operation implements the operation for releasing the tightening of the sleeve unit 10 on the upper arm. Although the geared motor 81 driven to turn in the reverse direction, but the electromagnetic brake 82 does not block the rotary shaft 81a1 of the engine section 81a the geared motor 81 and the engine section 81a is driven without being restricted in the operation thereof.
Although the gearbox engine 81 not driven to rotate in the forward or reverse direction, ie, the geared motor 81 is stopped, but the rotary shaft 81a1 of the engine section 81a the geared motor 81 is due to the electromagnetic brake 82 blocked. In this state, the braking force of the electromagnetic brake 82 on the spool roller 88 through the rotary shaft 81a1 of the engine section 81a , the Reduziereinrichtungsabschnitt 81b , the output shaft 81c , the gears 85 . 86 . 87 and the wave 87a exercised and thereby restricts the rotary operation of the reel 88 one. Therefore, in this state, both the take-up and the feed operation of the second tightening belt become 15 stopped, which by the coil roller 88 take place, and the diameter of the hollow opening of the sleeve body 11 is kept constant.
Next, the firming force detecting means with which the blood pressure monitoring device 1 is provided according to the present embodiment. The firming force detecting means is for detecting the tightening force of the cuff unit 10 on an upper arm during the tightening operation of the cuff unit 10 described above for the purpose of establishing the optimum tightening state of the cuff unit 10 on the upper arm.
As apparent from the above description, in the blood pressure monitor 1 In the present embodiment, the firming force detecting means consists of an airbag 20 and an air system component 40 educated. The firming force detecting means is for detecting the tightening force of the tightening straps 14 . 15 on an upper arm and receives the tightening force as internal pressure of the airbag 20 ,
In particular, in the blood pressure monitoring device 1 the present embodiment, before driving the tightening length setting 80 for reducing the diameter of the hollow opening of the cuff body 11 a predetermined amount of air through the pressurizing pump 41 in the airbag 20 injected. Since the tightening length adjustment means described above 80 is driven to reduce the tightening length, the internal pressure of the airbag 20 , which is between the tightening straps 14 . 15 and the upper arm, with the pressure sensor 43 recorded and, consequently, by the tightening straps 14 . 15 tightening force applied to the upper arm based on the detected inner pressure of the airbag 20 detected.
The CPU 30 monitors the internal pressure of the above-described airbag 20 while the tightening length adjustment means 80 performs the tightening operation, stops the operation of the geared motor 81 when the internal pressure reaches a predetermined pressure value and at the same time actuates the electromagnetic brake 82 to the rotation of the bobbin 88 to stop. In this way, the tightening state of the cuff unit can 10 optimally manufactured on the upper arm.
15 FIG. 10 is a flowchart showing a processing method of the blood pressure monitoring device according to the present embodiment. FIG. 16 Fig. 15 is a timing chart showing, in the manner of a time series, an operating condition of each member of the blood pressure monitor according to the present embodiment. 17 FIG. 12 is a schematic diagram illustrating a fixing operation for fixing the cuff unit according to the present embodiment to an upper arm. FIG. 18 Fig. 10 is a schematic diagram of a mounting state in which the sleeve unit according to the present embodiment is attached to an upper arm. Regarding the 15 to 18 Now, a processing method of the blood pressure monitoring device 1 according to the present embodiment, together with the operating condition of each member of the blood pressure monitoring device 1 or the attachment operation for the collar unit 10 and the state after the cuff unit 10 is mounted to be described. It should be noted that the in 15 shown flowchart following program in advance in the memory section 170 is stored, which in 11 is shown, and the CPU 300 reads the program from the memory section 170 and executes the program to proceed with the method.
As in 15 shown, only a patient actuates an operating button of the operating portion 190 in the display unit 100 to turn on the power. Then put the battery 180 electrical power as power source to the CPU 130 at. Then the CPU issues 130 the CPU 30 a drive command through the communication units 132 . 32 and consequently, electric power will be from the battery 50 as a power source to the CPU 30 created. Consequently, the CPU becomes 30 powered and the blood pressure monitor 1 initialized (step S201). As in 16 are shown at the time t0 when the blood pressure monitor 1 initialized, corresponding operations of the geared motor 81 , the electromagnetic brake 82 and the pressurizing pump 41 stopped, ie are in the OFF state, and the exhaust valve 42 is in the open state, which allows the interior of the airbag 20 communicating with the outside and equalizing the cuff pressure to the air pressure, and that through the pressure sensor 43 detected cuff pressure has the same value as the air pressure.
Next, the patient holds the handle 62 the cuff unit 10 in the right hand 320 and leads the left hand 220 which is a different hand than the right hand 320 which is the handle 62 holds, in the direction of an arrow C, which in 17 is shown in the hollow opening of the sleeve body 11 of the cuff unit 10 one. As in 18 The patient then moves the cuff unit 10 to the upper arm 210 of the left arm 200 , maintains the state in which the cuff unit 10 on the upper arm 210 of the left arm 200 attached while holding the push button 64 , which is on the handle 62 is provided with the thumb 321 the right hand 320 pushes which handle 62 holds.
As in 15 shown causes the CPU 30 in response to pressing the push button 64 the temporary application of pressure to the airbag by the patient 20 (Step S202). As in 16 shown, the CPU closes 30 especially at a time t1 when the push button 64 is pressed, the exhaust valve 42 to prevent the interior of the airbag 20 communicates with the outside, and then starts to drive the pressurizing pump at time t2 41 for injecting air into the airbag 20 , Then the CPU stops 30 driving the pressurizing pump 41 at a time t3 when a predetermined time has elapsed. Here is the time for which the pressurization pump 41 a time sufficient to allow the injection of a predetermined amount of air into the interior of the airbag 20 is required. Consequently, the temporary application of pressure to the airbag 20 completed (step S203).
Next, the CPU starts 30 , as in 15 shown with the tightening operation of the sleeve unit 10 on the upper arm (step S204). At this time, the CPU determines 30 whether tightening the cuff unit 10 at the upper arm has reached a predetermined tightening state (step S205). If the predetermined tightening state has not been reached (NO in step S205), the CPU sets 30 the tightening operation of the cuff unit 10 on the upper arm. When the predetermined tightening state has been reached (YES in step S205), the CPU ends 30 the tightening operation of the cuff unit 10 on the upper arm (step S206).
As in 16 shown drives the CPU 30 in particular at a time t4 the geared motor 81 for rotating in the forward direction, thereby with the Aufwickelbetätigung the second tightening belt 15 to start, which by the coil roller 88 he follows. Then the CPU causes 30 that the pressure sensor 43 the cuff pressure of the airbag 20 detected during the execution of the Aufwickelbetätigung. At the time t5, when the detected cuff pressure reaches a predetermined threshold, the CPU ends 30 driving to causing the rotation of the geared motor 81 in the forward direction and simultaneously drives the electromagnetic brake 82 to the rotation of the bobbin 88 to stop. Here, the threshold value described above is based on a tightening force of the cuff unit 10 determined in advance on the upper arm, which is suitable for measuring the blood pressure value.
While the cuff unit 10 with an optimal toning force on the upper arm 210 is tightened or tightened, here is guaranteed that the tightening straps 14 . 15 the airbag 20 against the upper arm 210 to press.
