The surface is e.g., a surface for receiving the pressure contact member 22 that is extended in the length direction and is deformed by swinging (to avoid interference). The plate may also be provided with a groove-shaped recess (not shown).
[0057] By providing such a contact portion, the vacuum blood collection tubes 3a, 3b, and 3c are 11, and the needle tube 17 is properly inserted into the vacuum blood collection tubes 3a, 3b, and 3c. At the same time, it becomes possible to stably hold the vacuum blood collection tubes 3a, 3b, and 3c. By providing such a recess, the vacuum blood collection tubes 3a, 3b, 3c can be securely held, while the outer diameter of the blood collection tube holder body 11 is reduced to allow for easy gripping. In addition, when such a recess is provided, In this case, the tongue-shaped protruding piece 20 or the pressure contact member 22 is brought into contact with the bottom surface of the recess. Alternatively, they may be prevented from contacting each other.
[0058] The number of the pressure contact members 22 and the tongue-shaped protruding pieces 20 is not particularly limited, and may be any number. The tongue-shaped protruding piece 20 can be attached to the inside of the blood collection tube holder body 11. It may be a member that protrudes from the peripheral surface, or may be a separate member that is fixed to the blood collection tube holder body 11. Furthermore, the tongue-shaped protruding piece 20 can provide sufficient holding force. In such a case, the first reinforcing piece 25, the second reinforcing piece 26, or The locking portion 27 may be omitted.
[0059] The needle base 15 may be integrally formed with the protruding portion 14. The connector 15a may be provided on the protruding portion 14 separately from the needle hub 15. In addition, the male connector 15a may be provided with a locking member provided with a female screw. In addition, instead of the male connector 15a, a blood collection needle tube to be inserted into a blood vessel may be provided on the needle base 15. You can do this.
[0060] In addition, in the blood collection kit 2, the blood collection tool 5 may be a tool other than a butterfly needle, and may be a flexible It may be connected to the blood collection tube holder body 11 without the tube 52. The blood collection tool 5 does not have a flexible tube 52, but has an extension with a suitable connector. It may be connected to the blood collection tube holder body 11 via a tube.
[0061] In addition, the material of the parts of the blood collection tube holder body 11 other than the needle tube 17 and the rubber sleeve 18 In addition to polypropylene, other materials include polycarbonate, polystyrene, and acrylic nitrite. ABS resin, polyethylene terephthalate, polyvinyl chloride or polymethyl methacrylate resin (acrylic resin), etc. can be used. The same applies to the support member 12. The material of the rubber sleeve 18 is not limited to isoprene rubber. Other examples include silicone rubber, butadiene rubber, butyl rubber, natural rubber, and urethane rubber. Alternatively, fluororubber or the like can be used.
[0062] Next, other configuration examples of the blood collection tube holder 1 and the blood collection kit 2 will be described. In the description, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals and detailed description is omitted. The explanation will be omitted.
[0063] FIG. 6 shows the first contact portion 11d and the second contact portion 11c that contact the outer peripheral surface of the flange portion 36 of the vacuum blood collection tube 3c. and the second contact portion 11e are provided on the inner peripheral surface of the blood collection tube holder body 11, and the pressure contact member 22 1 shows an example in which a locking portion 11f is provided on the second contact portion 11e instead of the locking portion 27 provided on the first contact portion 11f. As shown in FIG. 6, the blood collection tube holder 1 of this example is similar to the example shown in FIG. It is part of the configuration of a blood collection kit 2 that includes a blood collection tool 5.
[0064] FIG. 7 is an explanatory cross-sectional view of the blood collection tube holder body 11 in the example shown in FIG. In Fig. 7, the needle hub 15, the needle tube 17, and the rubber sleeve 18 are omitted. In this way, the first contact portion 11d and the second contact portion 11e are in contact with the inner periphery of the blood collection tube holder body 11. The surface protrudes toward the central axis side, and continues in the axial direction from the bottom 13 toward the opening side. The first contact portion 11d and the second contact portion 11e are configured in a rib shape. 11e are arranged at four positions in the circumferential direction of the blood collection tube holder body 11, and are arranged alternately in
[0065] The first contact portion 11d is configured to have a stepped shape with a large protrusion on the bottom portion 13 side, and The first contact portion 11d has a step portion 11d1 at the end of the opening side. The amount of protrusion gradually decreases toward the mouth side, and an inclined portion 11d2 is provided that connects to the inner circumferential surface. Similarly, the second contact portion 11e is configured to have a stepped shape with a large protrusion on the bottom portion 13 side, and A step portion 11e1 is provided at the end of the opening side of the second contact portion 11e. The tube 3c is provided with a locking portion 11f that locks onto the flange portion 36 of the vacuum blood collection tube 3c.
[0066] The axial lengths of the first contact portion 11d and the second contact portion 11e are not particularly limited. However, in this example, the length of the hollow portion 16 of the blood collection tube holder body 11 in the axial direction is about 1 / 4 of the length of the hollow portion 16. It is set to 3.
[0067] In this example, the vacuum blood collection tubes 3a and 3b are abutted against the tip surfaces of the vacuum blood collection tubes 3a and 3b. The third contact portions 11g for positioning the bottom portion 13b in the axial direction are provided at four locations on the inner surface of the bottom portion 13. The third contact portion 11g protrudes toward the opening side, and when viewed from the opening side, the hollow portion 16 The third contact portion 1 is made up of four arc-shaped protrusions centered on the central axis of the third contact portion 1. By providing the needle 1g, the vacuum blood collection tubes 3a and 3b can be positioned at appropriate positions in the axial direction. This can prevent the vacuum blood collection tubes 3a and 3b from tilting after piercing 17.
[0068] Furthermore, in this example, the holding member 12 accommodates the portion other than the trapezoidal portion 21a of the fitting member 21. The first recess 11h accommodates the trapezoidal portion 21a of the fitting member 21 and is swayed by the pressure. A second recess for accommodating at least a portion of the contact member 22 and the tongue-shaped protruding piece 20 (to avoid interference) The recess 11i is provided on the inner peripheral surface of the blood collection tube holder body 11. By providing such a first recess 11h and a second recess 11i, the blood collection tube holder body 11 The outer diameter can be reduced to improve gripping and operability. Alternatively, by providing the second recess 11i, the thickness and shape of the holding member 12 can be designed with a high degree of freedom. Therefore, the elastic force of the pressure contact member 22 is made larger than that of the conventional one, and a sufficient holding force is generated. can be done.
[0069] The first recess 11h is formed at the opening end of the inner circumferential surface of the blood collection tube holder body 11 in the circumferential direction. The first recess 11h is configured as a continuous (extending) groove. A positioning recess 11h1 for accommodating the positioning protrusion 21c of the holding member 12, and a positioning recess 11h2 for accommodating the positioning protrusion 21c of the holding member 12 The retaining projections 21c are provided at corresponding positions to the retaining recesses 11h2. It is being done.
[0070] The second recess 11i is located at a position corresponding to the pressure contact member 22 on the inner circumferential surface of the blood collection tube holder body 11. The recess 11h is formed in a groove shape extending in the axial direction from the first recess 11h toward the bottom 13 side. By configuring the second recess 11i in this way, the vacuum blood collection tubes 3a, 3b, and 3c can be inserted easily. The arm portion 23 and the fitting member 2 that supports it are subjected to a large moment when the arm portion 23 swings due to the Since the degree of freedom in design of the vacuum blood collection tube 1 is increased, the elastic force of the pressure contact member 22 can be increased. In addition, the second recess 11i can be prevented from falling off. On the bottom surface of the bottom 13 side, an additional recess 11i1 is provided, the depth of which is increased in correspondence with the tongue-shaped protruding piece 20. It is provided.
[0071] The depth of the first recess 11h and the second recess 11i is not particularly limited. The smaller the step between the inner circumferential surface of the blood vessel holder body 11 and the inner circumferential surface of the fitting member 21, the better. It is preferable that the depth is such that the inner peripheral surface of the fitting member 21 is flush with the inner peripheral surface of the fitting member 21 .
[0072] By making the inner peripheral surface of the blood collection tube holder body 11 and the inner peripheral surface of the fitting member 21 flush with each other, the vacuum collection tube holder body 11 can be easily used. When inserting or removing the blood vessels 3a, 3b, and 3c, labels or sticker-type truth marks attached to the outer surfaces of these vessels are used. Prevents the sealing member 34 of the empty blood collection tube 3c from getting caught on a step and peeling off or being damaged. It is possible.
[0073] In addition, only one of the first recess 11h and the second recess 11i is provided. The first recess 11h may include a positioning recess 11h1 and a retaining recess 11h. Alternatively, only the additional recess 11i1 may be provided in the second recess 11i. may be omitted.
[0074] In this example, the thickness of the inner surface of the tongue-shaped protruding piece 20 gradually decreases toward the tip. The inclined surface 20a is provided, and the corners of the tip of the inclined surface 20a are appropriately rounded. Therefore, contact with the holding member 12 and deformation of the holding member 12 and the tongue-shaped protruding piece 20 after contact are improved. This ensures that the process goes smoothly.
[0075] The protruding portion 14 of the blood collection tube holder body 11 has two threads that are threaded with the male thread of the needle base 15. A female screw 14a is provided, but in this example, two threads are overlapped with each other in the axial direction. By arranging it so that it does not get in the way, it is possible to simplify the structure of the mold for resin molding.
[0076] FIG. 8 is an external view of the holding member 12 in the example shown in FIG. 6. As described above, in this example, In this example, the locking portion 27 is omitted. By providing the holding member 12 at the position, it is possible to easily assemble the holding member 12 to the blood collection tube holder body 11. Furthermore, in this example, the second reinforcing piece 26 maintains an appropriate holding force while the first By omitting the reinforcing piece 25, the insertion resistance at the start of insertion of the vacuum blood collection tubes 3a, 3b, and 3c is reduced. I'm trying to reduce it.
[0077] In this way, only one of the first reinforcing piece 25 and the second reinforcing piece 26 is provided. In this way, the holding force of the holding member 12 can be appropriately adjusted. It is possible to provide the first reinforcing piece 25 and the second reinforcing piece 26 for each pressure contact member 22. The way of attaching the first reinforcing piece 25 and the second reinforcing piece 26 may be different, or both the first reinforcing piece 25 and the second reinforcing piece 26 may be omitted. It may be omitted.
[0078] FIG. 9A is an explanatory cross-sectional view showing an enlarged view of the first contact portion 11d, and FIG. 9B is an explanatory cross-sectional view showing the second contact portion 11d. 9A is an explanatory cross-sectional view showing an enlarged view of a portion 11e of the vacuum blood collection tube. 3c, the tip surface of the flange-shaped portion 36 abuts against the step portion 11d1, and the flange-shaped portion 36 is positioned in the axial direction. In addition, the outer peripheral surface of the flange-shaped portion 36 abuts against the lower top surface 11d3 on the opening side. As a result, the vacuum blood collection tube 3c is positioned in the radial direction and is also aligned with respect to the blood collection tube holder body 11. Furthermore, even if the vacuum blood collection tube 3c is tilted when inserted, the inclined portion 11 prevents the tube from tilting. d2, the outer peripheral surface of the flange-shaped portion 36 is guided to a state of contact with the top surface 11d3. It has become.
[0079] As shown by the imaginary line in FIG. 9B, the vacuum blood collection tube 3c is also attached to the second contact portion 11e. The tip end surface of the flange portion 36 abuts against the step portion 11e1, so that the flange portion 36 is positioned in the axial direction. The outer peripheral surface of the flange-shaped portion 36 abuts against the lower top surface 11e3 on the opening side, The locking portion 14 prevents the tube holder 11 from tilting relative to the tube holder body 11. The engagement of the flange portion 36 with the 11f prevents the vacuum blood collection tube 3c from falling off. .
[0080] In this example, the locking portion 11f is provided so as to protrude further from the top surface 11e3. The locking portion 11f has a parallel surface 11f1 at the top thereof so as to be substantially parallel to the central axis, The opening-side inclined surface 11f1 has a protruding amount that gradually decreases toward the opening side on the opening side of the parallel surface 11f1. f2, and the amount of protrusion gradually decreases toward the bottom 13 side of the parallel surface 11f1. The bottom side inclined surface 11f3 is trapezoidal. , and is provided so as to be connected to the inner peripheral surface, and is similar to the inclined portion 11d2 of the first contact portion 11d. It performs its function.
[0081] When the vacuum blood collection tube 3c is inserted, the blood collection tube holder body 11 and the flange-shaped portion 36 are elastically deformed. By shaping the flange portion 36, it is necessary to make the flange portion 36 go over the locking portion 11f. Therefore, the insertion resistance is increased when the corner 36a on the tip side (bottom 13 side) of the flange-shaped portion 36 is inclined toward the opening. The angle 3 of the base end side (opening side) of the flange-shaped portion 36 increases when the flange-shaped portion 36 abuts against the inclined surface 11f2. 6b is in contact with the bottom side inclined surface 11f3. The decrease in the insertion resistance is felt as a clicking sensation, and the vacuum blood collection tube 3c is properly inserted. You can tell just by feeling it with your fingertips that it has been placed in the right position.
[0082] In this example, a parallel surface 11f1 is provided between the opening-side inclined surface 11f2 and the bottom-side inclined surface 11f3. Specifically, the parallel surface 1 If 1f1 is not provided, the corner 36a on the tip side of the flange-shaped portion 36 will not be in contact with the opening-side inclined surface 11. After passing through f2, the flange-shaped portion 36 contacts the opening side inclined surface 11f2 of the four locking portions 11f and the bottom The vacuum blood collection tube 3c is clamped at the corner between the side inclined surfaces 11f3, and the vacuum blood collection tube 3c is The vacuum blood collection tube 3c is easily tilted relative to the blood collection tube holder main body 11. If the flange portion 36 is tilted, the corners 36b on the base end side of the flange portion 36 will be different for each of the four locking portions 11f. At different times, the bottom inclined surface 11f3 may come into contact with the bottom inclined surface 11f3, causing a continuous clicking sensation. As a result, it may be difficult for the user to understand the appropriate placement of the vacuum blood collection tube 3c.
[0083] In contrast, a parallel surface 11f1 is provided between the opening-side inclined surface 11f2 and the bottom-side inclined surface 11f3. By doing so, after the corner 36a on the tip side of the flange-shaped portion 36 passes over the opening-side inclined surface 11f2, Since it is possible to prevent the vacuum blood collection tube 3c from tilting, the proximal end side of the flange-shaped portion 36 The corners 36b are brought into contact with the bottom side inclined surfaces 11f3 of the four locking portions 11f at approximately the same time. This allows for an appropriate clicking sensation to be generated.
[0084] In this example, the step portion 11e1 and the bottom side inclined surface 11f3 are connected to the bottom 13 side end (top surface 11f3). The distance D1 between the flange portion 36 and the boundary ... (In other words, at a position spaced a distance D2 from the step portion 11e1, the By providing the bottom side inclined surface 11f3 so as to protrude further than the bottom side inclined surface 11f3, This allows the angle of inclination θ relative to the axis to be set as small as approximately 5°. By setting the axial dimension D2 of the flange-shaped portion 36 to be smaller than the axial dimension D1, the flange-shaped portion 36 can be formed without a step. The bottom side inclined surface 11f3 is sandwiched between the flange portion 36 and the bottom side inclined surface 11f3. Since it is possible to increase the pressing force of the surface 11f3, when the inclination angle θ is set small, This also ensures that the vacuum blood collection tube 3c is prevented from falling off.
[0085] By setting the tilt angle θ to a small value, the vacuum blood collection tube 3c can be easily removed from the blood collection tube holder 1. In other words, the locking portion 11f of this example reduces the resistance when the true This makes it possible to prevent the empty blood collection tube 3c from falling off and to make it easy to remove.
[0086] The shape of the locking portion 11f is not limited to such a trapezoidal shape, but may be a pyramidal shape. It may be in the shape of a pillar, a dome, a square pillar, or any other suitable shape. When the feeling of engagement is not important, the locking portion 11f may be configured to have no parallel surface 11f1. The opening-side inclined surface 11f2 and the bottom-side inclined surface 11f3 may be formed of curved surfaces. The angle of inclination of the opening-side inclined surface 11f2 and the bottom-side inclined surface 11f3 may be It goes without saying that there is no particular limitation.
[0087] In this way, the first contact portion 11d and the second contact portion 11e are formed on the inner peripheral surface of the blood collection tube holder body 11. 11e and a locking portion 11f is provided on the second abutting portion 11e. The empty blood collection tube 3c can be stably held and prevented from falling off. Also, the overcap type vacuum blood collection tube 3a and the rubber stopper cap type vacuum blood collection tube 3 It goes without saying that b can be held in the same manner as in the example shown in FIG. 1 to prevent it from falling off.
[0088] The number of the first contact portions 11d and the second contact portions 11e is not particularly limited. Furthermore, the inner circumferential surface of the blood collection tube holder body 11 is provided with a first Alternatively, only the contact portion 11e of the blood collection tube holder body 11 may be provided on the inner circumferential surface of the blood collection tube holder body 11. Alternatively, only the first contact portion 11d may be provided, and the locking portion 27 may be provided on the pressure contact member 22.
