US 7708027 B2Abstract
18. The connector as set forth in claim 16, wherein the pin comprises a top end portion possessing a tapering outer configuration that gradually tapers toward the top of the pin. Description
As shown in FIG. 1, the connector 1A includes a housing 3A, and a first valve disk 6 a and a second valve disk 6 b which are contained in the housing 3A.
As shown in FIGS. 2 and 3, the first female-side connecting port 30 (the first cap 36) and the second female-side connecting port 31 (the second cap 37) are provided with the first valve disk 6 a and the second valve disk 6 b, respectively. In addition, the first female-side connecting port 30 and the second female-side connecting port 31 are each so configured that a tube constituting a passage (for example, a tip projecting portion of a syringe, or a hub or sheath which itself is independent) can be connected thereto by insertion.
The center line of the first female-side connecting port 30 and the center line of the second female-side connecting port 31 are located in correlation of skew lines, and form an angle of about 90�. In the following description, the direction parallel to the center line of the first female-side connecting port 30 will be referred to as “the Y-axis direction”, and the direction parallel to the center line of the second female-side connecting port 31, i.e., the direction perpendicular to the Y-axis direction will be referred to as “the X-axis direction”.
The first valve disk 6 a and the second valve disk 6 b are each formed of elastic material. The elastic material is not particularly limited. Examples of the elastic material include various rubber materials such as silicone rubber, etc. and various thermoplastic resins such as polybutadiene, EVA, styrene-based elastomer, etc. Incidentally, the first valve disk 6 a and the second valve disk 6 b are substantially the same in shape and operation, and, therefore, the first valve disk 6 a will be representatively described below.
As shown in FIGS. 3 and 8( a), the first valve disk 6 a is composed of a substantially cylindrical barrel 62 of which the center line is directed in parallel to the Y-axis direction, and a top (head) 61 formed on one end side of the barrel 62.
The barrel 62 is provided therein with a pin insertion space (hollow section) 65 having a shape corresponding to the shape of a pin 4 a which will be described later.
In addition, a flange 621 enlarged in outside diameter as compared with the barrel 62 is formed on the other end side of the barrel 62. When the first valve disk 6 a is installed (contained) in the housing 3A, the flange 621 is clamped between the first cap 36 and the main body 35. This ensures that the first valve disk 6 a is assuredly fixed (in a liquid-tight condition) in the housing 3A (see FIG. 3).
Besides, the outer peripheral surface 622 of the barrel 62 is provided with a plurality (three, in this embodiment) of grooves 623 along the whole circumference on the side of the flange 621. This ensures that when the first valve disk 6 a is compressed in the axial direction (the Y-axis direction), the barrel 62 can easily be elastically deformed in the Y-axis direction (see FIG. 5).
In addition, the first valve disk 6 a (the barrel 62) is provided on the top 61 side thereof with a taper 624 gradually decreasing in outside diameter toward the top 61. This ensures that when no tube is connected to the first female-side connecting port 30, the taper 624 abuts on the inside surface of the first cap 36, whereby the top 61 (the top face 611) can be prevented from protruding from the first female-side connecting port 30, i.e., the height of the top face 611 in the Y-axis direction can be restricted (see FIG. 3).
The top 61 is provided with a top slit 63 extending (penetrating) from the top face 611 to the pin insertion space 65. Incidentally, the top slit 63 may be formed so as to be closed, or so as to be opened, in the natural state of the first valve disk 6 a (the top 61).
As shown in FIGS. 2 and 3, the connector 1A is provided further with solid pins 4 a and 4 b which are located (inserted) in the pin insertion space 65 of the first valve disk 6 a and in the pin insertion space 65 of the second valve disk 6 b, respectively. In addition, the pins 4 a and 4 b are each installed movably in the housing 3A.
As shown in FIG. 3, in the condition where a male lure (tube) 100 is not connected to the first female-side connecting port 30 (hereinafter referred to as “the non-connected condition”), the pin insertion space 65 in the first valve disk 6 a is substantially wholly filled up with the pin 4 a. This prevents a liquid from stagnating in the pin insertion space 65. In addition, since the pin 4 a is a solid member not having any hollow section, stagnation of a liquid in the pin 4 a is also prevented.
Besides, as shown in FIG. 2, also in the condition where a male lure (tube) 200 is not connected to the second female-side connecting port 31 (hereinafter referred to as “the non-connected condition”), similarly, the pin insertion space 65 in the second valve disk 6 b is substantially entirely filled up with the pin 4 b. This prevents a liquid from stagnating in the pin insertion space 65. In addition, since the pin 4 b is a solid member not having any hollow section, stagnation of a liquid in the pin 4 b is also prevented.
Incidentally, since the pins 4 a and 4 b are substantially the same in shape and operation, the pin 4 a will be representatively described below.
As shown in FIGS. 3 and 8( b), the pin 4 a has a top 41 and a tapered part (trunk) 42.
The tapered part 42 is a part, gradually decreasing in outside diameter toward the top 41, of the pin 4 a. As shown in FIG. 5, when the male lure 100 is connected to the first female-side connecting port 30 (this condition will hereinafter be referred to as “the connected condition”) and the pin 4 a is moved in the Y-axis direction, a clearance 651 is assuredly generated between the inside of the barrel 62 of the first valve disk 6 a and the tapered part 42.
With the top 41 formed in such a shape, in the connected condition, the top 41 (the pin 4 a) can easily enter into the top slit 63 and, therefore, the top slit 63 can be opened more assuredly. Besides, in the connected condition, communication between a passage 101 in the male lure 100 and the clearance 651 (the pin insertion space 65) is established through the top slit 63 thus opened.
As shown in FIGS. 2 and 3, the connector 1A is provided further with urging sections 2 a and 2 b for urging the pins 4 a and 4 b in the Y-axis direction and the X-axis direction, respectively. Incidentally, since the urging sections 2 a and 2 b are substantially the same in shape and operation, the urging section 2 a will be representatively described below.
As shown in FIG. 3, the urging section 2 a has an abutting part (head) 21 which abuts on a bottom face 421 of the tapered part 42 of the pin 4 a, and a barrel 22 formed on one end side of the abutting part 21. The urging section 2 a is contained in a cylindrical space 351 formed inside the main body 35 of the housing 3A.
The barrel 22 is composed of a bellows-like tubular body. Specifically, the barrel 22 assumes a bellows-like form in which large-diameter ring parts 221 and small-diameter ring parts 222 are alternately arranged along the Y-axis direction. Such a barrel 22 functions as an urging means for urging the pin 4 a in the Y-axis direction (the direction in which the pin 4 a is inserted into the pin insertion space 65).
In addition, while the barrel 22 is in charge of most of the urging force for urging the pin 4 a to move toward the pin insertion space 65, the abutting part 21 may in charge of part of the urging force.
Besides, the material constituting the urging parts 2 a and 2 b is not particularly limited; for example, the materials mentioned above in relation to the first valve disk 6 a and the second valve disk 6 b can be used.
The set of the first valve disk 6 a, the pin 4 a and the urging section 2 a and the set of the second valve disk 6 b, the pin 4 b and the urging section 2 b are so arranged that the center axes of the two sets are located in correlation of skew lines. This configuration has the merit that the volume of the liquid circulation space 38 can be made extremely small, as compared with the case where the center axes of the two sets intersect each other on a plane.
In addition, the set of the first valve disk 6 a, the pin 4 a and the urging section 2 a and the set of the second valve disk 6 b, the pin 4 b and the urging section 2 b share the liquid circulation space 38. Namely, side parts of the two sets are connected to each other through the liquid circulation space 38. This ensures that even when a liquid flows from the side of the first valve disk 6 a into the liquid circulation space 38 or flows from the side of the second valve disk 6 b into the liquid circulation space 38, the liquid will pass through the liquid circulation space 38, so that stagnation of the liquid can be prevented from occurring.
In the non-connected condition, the top 61 of the first valve disk 6 a is inserted in the first female-side connecting port 30 (see FIG. 3). The inside diameter of the first female-side connecting port 30 is slightly smaller than the outside diameter of the top 61 in its natural state. This ensures that in the non-connected condition, the top 61 is fastened in the radial directions, whereby the top slit 63 is closed more securely.
Besides, in the non-connected condition, the top 61 of the second valve disk 6 b is inserted in the second female-side connecting port 31 (see FIG. 2). The inside diameter of the second female-side connecting port 31 is slightly smaller than the outside diameter of the top 61 in its natural state. This ensures that in the non-connected condition, the top 61 is fastened in the radial directions, whereby the top slit 63 is closed more securely.
As shown in FIG. 5, at the time of connecting the male lure 100 to the first female-side connecting port 30, the housing 3A is gripped and a tip portion of the male lure 100 is inserted progressively into the first female-side connecting port 30. During this operation, the tip face of the male lure 100 presses the top face 611 (the top 61) of the first valve disk 6 a, causing the barrel 62 of the first valve disk 6 a to contract accordingly. Simultaneously, the top 41 of the pin 4 a is pressed, causing the pin 4 a to move in the Y-axis direction. This movement generates a clearance 651 in the first valve disk 6 a, resulting in that communication between the clearance 651 and the liquid circulation space 38 is established through the space 351 in the housing 3A.
Besides, in this instance, the urging section 2 a (the barrel 22) is compressed, so that by the urging force of the urging section 2 a thus compressed, the top 41 of the pin 4 a is inserted into the top slit 63, enlarging the top slit 63 pushingly. Then, the top 41 of the pin 4 a abuts on the mouth 102 of the male lure 100, to enlarge the top slit 63 more assuredly, establishing communication between the top slit 63 and the passage 101 in the male lure 100.
Upon the connection as just-mentioned, as shown in FIG. 5 and FIG. 6 (FIG. 7), the passage 101 in the male lure 100 communicates with the passage 51 in the male-side connecting section 50 through the top slit 63, the pin insertion space 65 (the clearance 651) in the first valve disk 6 a, the space 351 in the housing 3A, and the liquid circulation space 38.
As mentioned above, since the pin 4 a is movable in the housing 3A, the length of insertion of the pin 4 a into the top slit 63 is constant. This ensures that the top slit 63 of the first valve disk 6 a is prevented from being broken, and the liquid-tightness at the top slit 63 is obtained sustainedly.
In the connected condition shown in FIGS. 5 to 7, when a liquid such as a liquid medicine is let flow from the passage 101 of the male lure 100, the liquid passes successively through the top slit 63, the pin insertion space 65 in the first valve disk 6 a, the space 351 in the housing 3A, the liquid circulation space 38, and the passage 51 in the male-side connecting section 50, to flow out through the mouth 52 of the male-side connecting section 50. In this instance, as best seen from FIG. 6, the space 353 capable of communicating with the liquid circulation space 38 is closed, so that the liquid is prevented from flowing to the side of the second valve disk 6 b. In addition, since the liquid circulation space 38 is so shaped as to prohibit stagnation (so shaped as not to have a cove-like part), substantially the whole amount of the liquid flowing in through the passage 101 in the male lure 100 will flow into the male-side connecting section 50, without stagnating. A tube (not shown) is preliminarily connected to the male-side connecting section 50, and the liquid can be let flow through the tube to the patient side.
When the male lure 100 in the connected condition shown in FIGS. 6 to 8 is detached, the first valve disk 6 a is restored, by the restoring force (the urging force) of the barrel 62, to a position where the top 61 of the first valve disk 6 a is fastened by the inner periphery of the first female-side connecting port 30. As a result, the top slit 63 is closed. Besides, under the restoring force (the urging force) of the urging section 2 a, the pin 4 a is returned to a position such as to substantially entirely fill up the pin insertion space 65 in the first valve disk 6 a. In this manner, the connector 1A is returned into the non-connected condition shown in FIG. 3.
As shown in FIG. 4, at the time of connecting the male lure 200 to the second female-side connecting port 31, the housing 3A is gripped, and a tip part of the male lure 200 is inserted progressively into the second female-side connecting port 31. During this operation, the tip face of the male lure 200 presses the top face 611 (the top 61) of the second valve disk 6 b, causing the barrel 62 of the second valve disk 6 b to contract accordingly. Simultaneously, the top 41 of the pin 4 b is pressed, causing the pin 4 b to move in the X-axis direction. This movement generates a clearance 651 in the second valve disk 6 b, resulting in that communication between the clearance 651 and the liquid circulation space 38 is established through the space 353 in the housing 3A.
Besides, in this instance, the urging section 2 b (the barrel 22) is compressed, so that by the urging force of the urging section 2 b thus compressed, the top 41 of the pin 4 b is inserted into the top slit 63, enlarging the top slit 63 pushingly. Then, the top 41 of the pin 4 b abuts on the mouth 202 of the male lure 200, to enlarge the top slit 63 more assuredly, establishing communication between the top slit 63 and the passage 201 in the male lure 200.
Upon the connection as just-mentioned, as shown in FIG. 4, the passage 201 in the male lure 200 communicates with the passage 51 in the male-side connecting section 50 through the top slit 63, the pin insertion space 65 (the clearance 651) in the second valve disk 6 b, the space 353 in the housing 3A, and the liquid circulation space 38.
As mentioned above, since the pin 4 b is movable in the housing 3A, the length of insertion of the pin 4 b into the top slit 63 is constant. This ensures that the top slit 63 of the first valve disk 6 b is prevented from being broken, and the liquid-tightness at the top slit 63 is obtained sustainedly.
In the connected condition shown as just-mentioned, when a liquid such as a liquid medicine is let flow from the passage 201 of the male lure 200, the liquid passes successively through the top slit 63, the pin insertion space 65 in the second valve disk 6 b, the space 353 in the housing 3A, the liquid circulation space 38, and the passage 51 in the male-side connecting section 50, to flow out through the mouth 52 of the male-side connecting section 50. In this instance, the space 351 capable of communicating with the liquid circulation space 38 is closed, so that the liquid is prevented from flowing to the side of the first valve disk 6 a. In addition, since the liquid circulation space 38 is so shaped as to prohibit stagnation (so shaped as not to have a cove-like part), substantially the whole amount of the liquid flowing in through the passage 201 in the male lure 200 will flow into the male-side connecting section 50, without stagnating.
When the male lure 200 in the connected condition just-mentioned is detached, the second valve disk 6 b is restored, by the restoring force (the urging force) of the barrel 62, to a position where the top 61 of the second valve disk 6 b is fastened by the inner periphery of the second female-side connecting port 31. As a result, the top slit 63 is closed. Besides, under the restoring force (the urging force) of the urging section 2 b, the pin 4 b is returned to a position such as to substantially entirely fill up the pin insertion space 65 in the second valve disk 6 b. In this manner, the connector 1A is returned into the non-connected condition shown in FIG. 2.
In the case where the male lures 100 and 200 are connected respectively to both the first female-side connecting port 30 and the second female-side connecting port 31, it is possible, for example, to let different liquids to flow into the connector 1A respectively through the passage 101 in the male lure 100 and the passage 201 in the male lure 200. The liquids flowing in respectively through the passages 101 and 201 mix with each other in the liquid circulation passage 38, and the liquid mixture flows out through the mouth 52 of the male-side connecting section 50. In the case where, for example, the male lure 100 is detached from the connector 1A (the first female-side connecting port 30) after the flow-in of the liquid from the male lure 100 into the connector 1A is finished, the liquid in the pin insertion space 65 of the first valve disk 6 a and the space 351 of the housing 3A is pushed out to the side of the male-side connecting section 50, due to the restoration of these component parts. This prevents the liquid in the male lure 100 from stagnating. In the case where, for example, the male lure 200 is detached from the connector 1A (the second female-side connecting port 31) after the flow-in of the liquid from the male lure 200 into the connector 1A is finished, similarly, the liquid in the pin insertion space 65 of the second valve disk 6 b and the space 353 of the housing 3A is pushed out to the male-side connecting section 50, due to the restoration of these component parts. This prevents the liquid in the male lure 200 from stagnating.
In addition, the materials of the housing 3A and the pins 4 a and 4 b are not particularly limited, but materials having appropriate hardness are preferably used. Examples of the usable material include polymeric materials such as polyethylene, polypropylene, and polycarbonate.
As shown in FIG. 11, the connector 1B has a housing 3B, and a first valve disk 6 a contained in the housing 3B.
The housing 3B has a main body 35B substantially cylindrical in shape, a first cap 36, a first male-side connecting section 50 a, and a second male-side connecting section 50 b. As shown in FIG. 12, the first male-side connecting section 50 a and the second male-side connecting section 50 b communicate with each other through a liquid circulation space 38, and the male-side connecting sections are so formed that their center lines coincide with each other. Specifically, the first male-side connecting section 50 a and the second male-side connecting section 50 b are so formed that a space 32 composed of a passage 51 a in the first male-side connecting section 50 a, the liquid circulation space 38, and a passage 51 b in the second male-side connecting section 50 b is substantially cylindrical in shape. In addition, the center axis of the space 32 and the center axis of a space 351 in the housing 3B are in positional correlation of skew lines (see FIGS. 12 and 13).
In this case, the first male-side connecting section 50 a is located on the upstream side (the right side, in FIG. 11) of the tube 300 to which a roller klemme or a pin needle of an infusion set, for example, is connected, and the second male-side connecting section 50 b is located on the downstream side (the left side, in FIG. 11) of the tube 300 to which a male lure, for example, is connected. Namely, the first male-side connecting section 50 a is connected to the tube 300 on the upstream side, and the second male-side connecting section 50 b is connected to the tube 300 on the downstream side.
Incidentally, the first male-side connecting section 50 a and the second male-side connecting section 50 b are each not limited to one which constitutes a lure taper (male lure); for example, one of the male-side connecting sections may be provided with a mouth (female lure) like the first female-side connecting port 30 (the first cap 36).
In the connected condition, the top 26 of the urging section 2′ is pressed by the pin 4 a, deforming a side part 25 of the urging section 2′ so as to bend to the hollow section 24 side (in the directions of arrows in FIG. 19) (as indicated by two-dotted chain lines in FIG. 18). This establishes communication between the pin insertion space 65 in the first valve disk 6 a and the liquid circulation space 38 through the space 351, i.e., the space on the upper side (in FIG. 18) of the urging section 2′, permitting a liquid to pass through the interior of the connector 1E.
Meanwhile, the first valve disk (the pin insertion space) and the pin are not limited to those shaped as shown in FIGS. 8( a) and 8(b), respectively. Here, other configuration examples of the first valve disk and the pin will be described. FIGS. 9 and 10 each show a longitudinal sectional view (a) showing other configuration example of the valve disk and a perspective view (b) showing other configuration example of the pin. The configuration examples of the first valve disk and the pin will be described below referring to these figures. The following descriptions will be centered on the differences from the first valve disk 6 a and the pin 4 a above-described, and description of the same items as above will be omitted.
The pin 4 c shown in FIG. 9( b) is the same as the pin 4 a described above, except for the number of the slant face 411 formed at the top 41 thereof.
The top 41 of the pin 4 c is provided with one slant face 411 inclined against the Y-axis direction (the axial direction), and a top face 413. This ensures that, in the connected condition, communication between the passage 101 in the male lure 100 and the clearance 651 (the pin insertion space 65) can be established through the top slit 63.
The first valve disk 6 c shown in FIG. 9( a) is the same as the first valve disk 6 a described above, except for the shape of a pin insertion space 65 c. This pin insertion space 65 c has a shape corresponding to the shape of the pin 4 c. Specifically, the pin insertion space 65 c is surrounded by a slant face 652 corresponding to the slant face 411, a flat face 653 corresponding to the top face 413, and a tapered surface (inner peripheral surface) 654 corresponding to the tapered part 42. This ensures that, in the non-connected condition, the pin insertion space 65 c can be substantially wholly filled up with the pin 4 c. In addition, the slit 63 in the first valve disk 6 c is formed at and in parallel to the boundary between the slant face 652 and the flat face 653.
This ensures that, in the connected condition, the clamping force for clamping the portion near the slant face 652 of the top 61 between the slant face 411 and the tip of the male lure 100 is weaker than the clamping force for clamping the portion near the flat face 653 of the top 61 between the top face 413 and the tip of the male lure 100, so that it is easier for the portion near the slant face 652 of the top 61 to be deformed. As a result, the slit 63 can be opened by the pin 4 c more assuredly.
The pin 4 d shown in FIG. 10( b) is the same as the pin 4 a described above, except for the shape of the top 41.
The top 41 of the pin 4 d is provided with two slant faces 411 substantially the same as those of the pin 4 a, a top face 413, and a recess 412. The recess 412 is formed in the top face 413 so as to range to both the two slant faces 411. Since the top 41 of the pin 4 d is shaped in this manner, in the connected condition, communication between the passage 101 in the male lure 100 and the clearance 651 (a pin insertion space 65 d) can be established through the top slit 63.
The first valve disk 6 d shown in FIG. 10( a) is the same as the first valve disk 6 a described above, except for the shape of the pin insertion space 65 d. The pin insertion space 65 d has a shape corresponding to the shape of the pin 4 d. To be more specific, the pin insertion space 65 d is surrounded by a slant face 652 corresponding to the slant face 411, a flat face 653 corresponding to the top face 413, a tapered surface (inner peripheral surface) 654 corresponding to the tapered part 42, and a projected surface 654 corresponding to the recess 412. This ensures that, in the non-connected condition, the pin insertion space 65 d can be substantially entirely filled up with the pin 4 d. In addition, in the connected condition, the portion near the flat face 653 of the top 61 is clamped between the top face 413 and the tip of the male lure 100, and the pin 4 d is moved.
