Next, the operation of the blood collection tube holder 1 of the present embodiment will be described.

In the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 to be connected to the blood collection tool 5, for example, as shown in FIG. The vacuum blood collection tube 3a is inserted into the inner peripheral side of the holding member 12 fitted in the main body 11. Here, the vacuum blood collection tube 3a is an overcap type, and is a blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and a rubber cap 32 that closes the open end of the blood collection tube body 31. And an outer tube (overcap) 33 made of synthetic resin made of a hollow bottomed tubular body that protects the blood collection tube main body 31 and the rubber cap 32. The outer tube 33 is fitted onto the rubber cap 32, and has an opening at the bottom that exposes a part of the rubber cap 32.

When the vacuum blood collection tube 3a is inserted into the inner peripheral side of the holding member 12, the pressure contact member 22 protruding from the fitting member 21 into the hollow portion 16 of the blood collection tube holder main body 11 is pressed against the vacuum blood collection tube 3a, and FIG. From the state shown by the virtual line, it swings and deforms toward the inner peripheral surface side of the blood collection tube holder main body 11. At this time, the arm-shaped portion 23 and the bent portion 24 of the pressure contact member 22 are substantially linear in cross section as a result of pressing by the vacuum collecting tube 3a, and are in their original state due to their own elastic force (virtual line shown in FIG. 3). It is pressed against the outer peripheral surface of the vacuum blood collection tube 3a in an attempt to return to the state of

On the other hand, when the vacuum collecting blood vessel 3a is inserted into the inner peripheral side of the holding member 12, the rubber cap 32 is brought into contact with the rubber sleeve 18 and the rubber sleeve 18 is further pressed toward the needle base 15. As a result, the needle tube 17 penetrates the rubber sleeve 18 and the rubber cap 32 and is inserted into the vacuum collection tube 3a, while the rubber sleeve 18 is compressed and forms a bellows shape between the rubber cap 32 and the needle base 15. It will be in a folded state.

When the needle tube 17 is inserted into the vacuum blood collection tube 3a, the needle tube 17 is communicated with the blood collection needle tube 51 via the hollow portion 19 of the needle base 15 and the flexible tube 52, so that the blood collection needle tube 51 of the blood collection tool 5 The blood sample collected by the blood sample is introduced into the vacuum blood collection tube 3a via the flexible tube 52 and the needle tube 17.

At this time, the rubber sleeve 18, which is compressed as described above and is folded in a bellows shape between the rubber cap 32 and the needle base 15, is vacuumed in an attempt to return to its original state by its own elastic force. Since the blood vessel 3a is pressed toward the opening side (fitting member 21 side), there is a concern that the vacuum blood collection tube 3a held by the pressure contact of the pressure contact member 22 may fall off from the blood collection tube holder main body 11.

However, in the blood collection tube holder 1 of the present embodiment, as a result of pressing by the vacuum collection tube 3a as described above, the arm-shaped portion 23 and the bent portion 24 of the pressure contact member 22 are substantially linear in cross section, and are bent. When the tip of the portion 24 comes into contact with the tongue-shaped protruding piece 20, the tongue-shaped protruding piece 20 is oscillated and deformed toward the inner peripheral surface side of the blood collection tube holder main body 11. When the tongue-shaped projecting piece 20 is swung as described above, it tries to return to its original state by its own elastic force, and presses the tip of the bent portion 24 toward the outer peripheral surface side of the blood collection tube.

As a result, the pressure contact member 22 is assisted in pressure contact with the outer peripheral surface of the vacuum collection tube 3a by the pressing force of the tongue-shaped protruding piece 20 in addition to its own elastic force, and the vacuum collection tube 3a has a stronger force. Can be retained. Therefore, even when the vacuum collection tube 3a is pressed toward the opening side by the compressed rubber sleeve 18, it is possible to prevent the vacuum collection tube 3a from falling off from the blood collection tube holder main body 11.

In the blood collection tube holder 1 of the present embodiment, when a predetermined amount of blood sample is stored in the vacuum collection tube 3a, the vacuum collection tube 3a is removed. At this time, the rubber sleeve 18 returns to its original state with the removal of the vacuum collection tube 3a and covers the needle tube 17 over its entire length, so that it is possible to prevent the blood sample from leaking from the needle tube 17 to the outside. ..

Further, in the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 and connected to the blood collection tool 5, for example, as shown in FIG. The vacuum collecting blood vessel 3b may be inserted into the inner peripheral side of the holding member 12 fitted in the blood vessel holder main body 11. Here, the vacuum blood collection tube 3b is a rubber stopper cap type, and is a rubber cap that closes the blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and the open end portion of the blood collection tube body 31. It has 32 and.

In the blood collection tube holder 1 of the present embodiment, the rubber sleeve 18 in which the vacuum collection tube 3b is compressed is the same as in the case of the overcap type vacuum collection tube 3a, even for the vacuum collection tube 3b of the rubber stopper cap type. It is possible to prevent the vacuum blood collection tube 3b from falling off from the blood collection tube holder main body 11 even when the vacuum collection tube 3b is pressed backward.

Further, in the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 to be connected to the blood collection tool 5, for example, as shown in FIG. The vacuum collecting blood vessel 3c may be inserted into the inner peripheral side of the holding member 12 fitted in the blood vessel holder main body 11. Here, the vacuum blood collection tube 3c is a seal type, and includes a blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and a seal member 34 that closes the opening end of the blood collection tube body 31. It has. The seal member 34 is configured to include, for example, a rubber valve body 35 at the center of a sheet made of an aluminum film. Further, the blood collection tube main body 31 is provided with a flange-shaped flange-shaped portion 36 extending outward from the open end portion. The flange-shaped portion 36 may be composed of another member fixed to the blood collection tube main body 31.

The blood collection tube holder 1 of the present embodiment also applies to the seal type vacuum collection tube 3c in the same manner as in the case of the overcap type vacuum collection tube 3a and the rubber stopper cap type vacuum collection tube 3b. Even when the 3c is pressed backward by the compressed rubber sleeve 18, it is possible to prevent the vacuum blood collection tube 3c from falling off from the blood collection tube holder main body 11. Further, since the seal type vacuum collecting blood vessel 3c includes the flange-shaped portion 36, the flange-shaped portion 36 can be locked to the locking portion 27 of the bent portion 24, and the vacuum collecting tube holder main body 11 can be more reliably vacuum-collected. It is possible to prevent the blood vessel 3c from falling off.

In the present embodiment, by providing the tongue-shaped protruding piece 20 on the blood collection tube holder main body 11, it is possible to generate an appropriate holding force without increasing the thickness and size of the entire holding member 12. As a result, the vacuum collecting

blood collection tube

3a, 3b, and 3c can be reliably prevented from falling off, and the blood collection tube holder main body 11 can be compactly configured. The grip of 11 is not hindered.

Further, in the present embodiment, the bent portion 24 comes into contact with the tongue-shaped protruding piece 20 after the insertion of the

vacuum collecting tubes

3a, 3b, and 3c has progressed to some extent, and before that, the elastic force that becomes the insertion resistance is the elasticity of the holding member 12. Since it is only a force, it is possible to easily insert the

vacuum collection tubes

It is possible to use methyl acid acid resin (acrylic resin) or the like, and the same applies to the holding member 12. Further, as the material of the rubber sleeve 18, other than isoprene rubber, for example, silicone rubber, butadiene rubber, butyl rubber, natural rubber, urethane rubber, fluorine rubber and the like can be adopted.

Next, another configuration example of the blood collection tube holder 1 and the blood collection kit 2 will be described. In the following description, the same configurations as those shown in FIGS. 1 to 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 6, a first contact portion 11d and a second contact portion 11e that come into contact with the outer peripheral surface of the flange-shaped portion 36 of the vacuum blood collection tube 3c are provided on the inner peripheral surface of the blood collection tube holder main body 11, and a pressure contact member is provided. An example is shown in the case where the locking portion 11f is provided in the second contact portion 11e instead of the locking portion 27 provided in the 22. As shown in FIG. 6, the blood collection tube holder 1 of this example is a part of the configuration of the blood collection kit 2 including the blood collection tool 5 as in the example shown in FIG.

FIG. 7 is an explanatory cross-sectional view of the blood collection tube holder main body 11 in the example shown in FIG. In FIG. 7, the description of the needle base 15, the needle tube 17, and the rubber sleeve 18 is omitted. As shown in FIG. 7, the first contact portion 11d and the second contact portion 11e project toward the central axis side on the inner peripheral surface of the blood collection tube holder main body 11, and from the bottom portion 13 to the opening side. It is configured in a rib shape that is continuous (extending) in the axial direction. Further, the first contact portion 11d and the second contact portion 11e are arranged at four positions in the circumferential direction of the blood collection tube holder main body 11 and are arranged alternately in the circumferential direction.

The first contact portion 11d has a stepped shape with a large protrusion amount on the bottom 13 side, and a step portion 11d1 is provided in the intermediate portion. Further, at the end of the first contact portion 11d on the opening side, an inclined portion 11d2 is provided so that the amount of protrusion gradually decreases toward the opening side and is connected to the inner peripheral surface. Similarly, the second contact portion 11e has a stepped shape with a large protrusion amount on the bottom 13 side, and a step portion 11e1 is provided in the intermediate portion. A locking portion 11f that locks to the flange-shaped portion 36 of the vacuum blood collection tube 3c is provided at the end of the second contact portion 11e on the opening side.

The axial lengths of the first contact portion 11d and the second contact portion 11e are not particularly limited, but in this example, the axial length of the hollow portion 16 of the blood collection tube holder main body 11. It is set to about 1/3 of the size.

Further, in this example, third contact portions 11g for axially positioning the

vacuum collection tubes

3a and 3b by contacting the tip surfaces of the

vacuum collection tubes

3a and 3b are provided at four locations on the inner surface of the bottom portion 13. ing. The third contact portion 11g protrudes toward the opening side and is composed of four arc-shaped protrusions centered on the central axis of the hollow portion 16 when viewed from the opening side. By providing such a third contact portion 11g, the

vacuum collection tubes

3a and 3b are arranged at appropriate positions in the axial direction, and the inclination of the

vacuum collection tubes

3a and 3b after penetrating the needle tube 17 is suppressed. be able to.

Further, in this example, the first recess 11h for accommodating a portion other than the trapezoidal portion 21a of the fitting member 21 of the holding member 12 and the trapezoidal portion 21a of the fitting member 21 are accommodated and oscillated pressure welding. A second recess 11i for accommodating (avoiding interference) at least a part of the member 22 and the tongue-shaped projecting piece 20 is provided on the inner peripheral surface of the blood collection tube holder main body 11. As described above, by providing the first recess 11h and the second recess 11i, the outer diameter of the blood collection tube holder main body 11 can be reduced to improve grip and operability. Further, by providing the first recess 11h or the second recess 11i, the degree of freedom in designing the thickness and shape of the holding member 12 is increased, so that the elastic force of the pressure welding member 22 is made larger than before, which is sufficient. A holding force can be generated.

The first recess 11h is formed in a groove shape that is continuous (extending) in the circumferential direction at the opening side end of the inner peripheral surface of the blood collection tube holder main body 11. Then, on the bottom surface of the first recess 11h, the positioning recess 11h1 accommodating the positioning protrusion 21c of the holding member 12 and the retaining recess 11h2 accommodating the retaining protrusion 21c of the holding member 12 are located at corresponding positions. It is provided.

The second recess 11i is formed in a groove shape extending axially from the first recess 11h toward the bottom 13 side at a position corresponding to the pressure contact member 22 on the inner peripheral surface of the blood collection tube holder main body 11. .. By configuring the second recess 11i in this way, the design of the arm-shaped portion 23 to which a large moment is applied when swinging due to the insertion of the

vacuum collecting tubes

3a, 3b, 3c and the fitting member 21 supporting the arm-shaped portion 23 Since the degree of freedom of the pressure contact member 22 is further increased, the elastic force of the pressure contact member 22 can be further increased to more reliably prevent the

vacuum collection tubes

3a, 3b, and 3c from falling off. Further, on the bottom 13 side of the bottom surface of the second recess 11i, an additional recess 11i1 having an increased depth corresponding to the tongue-shaped protruding piece 20 is provided.

The depths of the first recess 11h and the second recess 11i are not particularly limited, but there is a step generated between the inner peripheral surface of the blood collection tube holder main body 11 and the inner peripheral surface of the fitting member 21. The smaller the value is preferable, and the depth is more preferably such that the inner peripheral surface and the inner peripheral surface of the fitting member 21 are flush with each other.

By making the inner peripheral surface of the blood collection tube holder main body 11 and the inner peripheral surface of the fitting member 21 flush with each other, the label or seal type attached to the outer peripheral surfaces of the vacuum

blood collection tubes

3a, 3b, 3c can be used. It is possible to prevent the seal member 34 of the vacuum collection tube 3c from being caught in the step and being peeled off or damaged.

Note that only one of the first recess 11h and the second recess 11i may be provided. Further, as the first recess 11h, only the positioning recess 11h1 and the retaining recess 11h2 may be provided. Further, in the second recess 11i, the additional recess 11i1 may be omitted.

In this example, the tongue-shaped projecting piece 20 is provided with an inclined surface 20a whose thickness gradually decreases toward the tip on the tip side of the inner surface, and an appropriate roundness is provided at the corner of the tip of the inclined surface 20a. , The contact with the holding member 12, and the deformation of the holding member 12 and the tongue-shaped projecting piece 20 after the contact are made smoother.

Further, the protruding portion 14 of the blood collection tube holder main body 11 is provided with two female screws 14a screwed with the male screw of the needle base 15, but in this example, the two threads overlap each other in the axial direction. It is possible to simplify the structure of the resin molding mold by providing it so that it does not become.

FIG. 8 is an external view of the holding member 12 in the example shown in FIG. As described above, in this example, the locking portion 27 is omitted. Further, in this example, by providing the positioning protrusions 21b at four positions in the circumferential direction, the holding member 12 can be easily assembled to the blood collection tube holder main body 11. Further, in this example, the insertion resistance at the start of insertion of the

vacuum collection tubes

3a, 3b, 3c is reduced by omitting the first reinforcing piece 25 while maintaining an appropriate holding force by the second reinforcing piece 26. I try to reduce it.

As described above, only one of the first reinforcing piece 25 and the second reinforcing piece 26 may be provided, and by doing so, the holding force by the holding member 12 is appropriately adjusted. can do. The method of providing the first reinforcing piece 25 and the second reinforcing piece 26 may be different for each pressure welding member 22, or both the first reinforcing piece 25 and the second reinforcing piece 26 may be omitted. You may do so.

FIG. 9A is an enlarged explanatory cross-sectional view showing the first contact portion 11d, and FIG. 9B is an enlarged explanatory cross-sectional view showing the second contact portion 11e. As shown by a virtual line in FIG. 9A, the vacuum collection tube 3c is positioned in the axial direction when the tip surface of the flange-shaped portion 36 abuts on the step portion 11d1. Further, when the outer peripheral surface of the flange-shaped portion 36 abuts on the lower apex surface 11d3 on the opening side, the vacuum blood collection tube 3c is positioned in the radial direction and the inclination with respect to the blood collection tube holder main body 11 is prevented. Further, even when the vacuum collecting blood vessel 3c is tilted at the time of insertion, the tilted portion 11d2 guides the outer peripheral surface of the flange-shaped portion 36 to abut the top surface 11d3.

As shown by a virtual line in FIG. 9B, the vacuum blood collection tube 3c is similarly positioned in the axial direction by the tip surface of the flange-shaped portion 36 abutting on the stepped portion 11e1 in the second contact portion 11e. When the outer peripheral surface of the flange-shaped portion 36 comes into contact with the lower top surface 11e3 on the opening side, radial positioning and tilt prevention with respect to the blood collection tube holder main body 11 are performed. Then, by locking the locking portion 11f to the flange-shaped portion 36, the vacuum collecting blood vessel 3c is prevented from falling off.

In this example, the locking portion 11f is provided so as to further protrude from the top surface 11e3. Further, the locking portion 11f is provided on the top of the parallel surface 11f1 so as to be substantially parallel to the central axis, and the opening side inclined surface 11f2 in which the amount of protrusion gradually decreases toward the opening side on the opening side of the parallel surface 11f1. And, on the bottom 13 side of the parallel surface 11f1, it is configured in a trapezoidal shape having a bottom side inclined surface 11f3 in which the amount of protrusion gradually decreases toward the bottom 13 side. The opening-side inclined surface 11f2 is provided so as to be connected to the inner peripheral surface, and has the same function as the inclined portion 11d2 of the first contact portion 11d.

When inserting the vacuum blood collection tube 3c, it is necessary to elastically deform the blood collection tube holder main body 11 and the flange-shaped portion 36 so that the flange-shaped portion 36 gets over the locking portion 11f. Therefore, the insertion resistance increases when the corner portion 36a on the tip end side (bottom portion 13 side) of the flange-shaped portion 36 is in contact with the opening side inclined surface 11f2, and the base end side (opening side) of the flange-shaped portion 36. 36b is reduced when it is in contact with the bottom inclined surface 11f3. Then, the user can grasp that the vacuum collection tube 3c is arranged at an appropriate position only by the sensation of the fingertip by feeling the decrease from the increase in the insertion resistance as a click feeling.

In this example, the parallel surface 11f1 is provided between the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 so that this click feeling is appropriately generated. Specifically, when the parallel surface 11f1 is not provided, after the corner portion 36a on the tip end side of the flange-shaped portion 36 exceeds the opening side inclined surface 11f2, the flange-shaped portion 36 becomes the opening side of the four locking portions 11f. It will be sandwiched between the corners between the inclined surface 11f2 and the bottom inclined surface 11f3, and the vacuum collecting blood vessel 3c will be easily tilted with respect to the blood collecting tube holder main body 11. When the vacuum blood collection tube 3c is tilted with respect to the blood collection tube holder main body 11, the corner portion 36b on the base end side of the flange-shaped portion 36 comes into contact with the bottom side inclined surface 11f3 at different timings for each of the four locking portions 11f. In some cases, as a result of continuous click feeling, it may be difficult for the user to grasp the appropriate arrangement of the vacuum blood collection tube 3c.

On the other hand, by providing the parallel surface 11f1 between the opening side inclined surface 11f2 and the bottom side inclined surface 11f3, vacuum sampling is performed after the corner portion 36a on the tip side of the flange-shaped portion 36 exceeds the opening side inclined surface 11f2. Since it is possible to prevent the blood vessel 3c from tilting, it is appropriate to bring the corner portion 36b on the base end side of the flange-shaped portion 36 into contact with the bottom side inclined surface 11f3 of the four locking portions 11f at substantially the same timing. It is possible to generate a nice click feeling.

In this example, the distance D1 between the step portion 11e1 and the bottom 13-side end (boundary with the top surface 11e3) of the bottom inclined surface 11f3 is further set smaller than the axial dimension D2 of the flange-shaped portion 36 (in other words). Then, the bottom side inclined surface 11f3 is provided so as to protrude from the top surface 11e3 at a position separated from the step portion 11e1 by the distance D2), so that the inclination angle θ of the bottom side inclined surface 11f3 with respect to the central axis is about 5 °. It is possible to set it small. By setting the distance D1 smaller than the axial dimension D2 of the flange-shaped portion 36, the flange-shaped portion 36 is sandwiched between the stepped portion 11e1 and the bottom-side inclined surface 11f3, and the bottom-side inclined surface 11f3 with respect to the flange-shaped portion 36 is sandwiched. Since it is possible to increase the pressing force of the vacuum collecting tube 3c, it is possible to reliably prevent the vacuum collecting tube 3c from falling off even when the inclination angle θ is set small.

Then, by setting the inclination angle θ to be small, it is possible to reduce the resistance of the vacuum blood collection tube 3c when it is removed from the blood collection tube holder 1. That is, according to the locking portion 11f of this example, it is possible to achieve both prevention of the vacuum collecting tube 3c from falling off and ease of removal.

The shape of the locking portion 11f is not limited to such a trapezoidal shape, and may be another appropriate shape such as a pyramid shape, a dome shape, or a prismatic shape. Further, for example, when the click feeling is not important, the locking portion 11f may be configured in a shape that does not have the parallel surface 11f1. Further, the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 may be formed of a curved surface. Needless to say, the inclination angles of the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 are not particularly limited.

As described above, even when the first contact portion 11d and the second contact portion 11e are provided on the inner peripheral surface of the blood collection tube holder main body 11 and the locking portion 11f is provided on the second contact portion 11e. , The seal type vacuum collection tube 3c can be stably held and prevented from falling off. Further, in this case as well, it goes without saying that the overcap type vacuum collection tube 3a and the rubber stopper cap type vacuum collection tube 3b can be held in the same manner as in the example shown in FIG. 1 to prevent them from falling off.

The number of the first contact portion 11d and the second contact portion 11e is not particularly limited, and any number can be adopted. Further, only the second contact portion 11e may be provided on the inner peripheral surface of the blood collection tube holder main body 11, or only the first contact portion 11d may be provided on the inner peripheral surface of the blood collection tube holder main body 11. The pressure welding member 22 may be provided with a locking portion 27. Further, the first contact portion 11d and the second contact portion 11e may be configured so that the higher top surfaces 11d4 and 11e4 are in contact with the outer peripheral surfaces of the

vacuum collection tubes

3a and 3b. Further, the locking portion 11f may be provided separately from the second contact portion 11e on the inner peripheral surface of the blood collection tube holder main body 11.

FIG. 10 is a diagram showing an example in the case where the tongue-shaped protruding piece 20 is omitted in the example shown in FIG. In this example, the additional recess 11i1 of the second recess 11i is omitted together with the tongue-shaped projecting piece 20. Then, the size and shape of the second reinforcing piece 26 are appropriately adjusted, and when the pressure contact member 22 swings and deforms due to the insertion of the

vacuum collecting tubes

3a, 3b, 3c, the tip portion of the bent portion 24 is seconded. A sufficient holding force can be obtained by contacting the bottom surface of the recess 11i. As described above, when a sufficient holding force can be obtained only by the holding member 12, the tongue-shaped protruding piece 20 may be omitted.

It should be noted that the tip of the bent portion 24 is not brought into contact with the bottom surface of the second recess 11i, but the first reinforcing piece 25 is added to the pressure contact member 22 so that a sufficient holding force can be obtained. Good. Further, the second recess 11i may be configured so that the tip end portion of the bent portion 24 comes into contact with a portion other than the second recess 11i on the inner peripheral surface of the blood collection tube holder main body 11. Further, the locking portion 11f may be provided on the inner peripheral surface of the blood collection tube holder main body 11 separately from the second contact portion 11e, or may be provided on the pressure contact member 22. Good. Further, although not shown, the tongue-shaped protruding piece 20 may be omitted in the example shown in FIG.

Therefore, the needle base 15 is described in this way. By providing the female connector 15b, the male connector 61 of the syringe 6 can be directly connected to the blood collection tube holder 1.

Therefore, according to the blood collection tube holder 1 shown in FIG. 11, the blood sample collected by the syringe 6 can be safely dispensed into the

vacuum collection tubes

3a, 3b, and 3c. When the blood collection needle tube connected to the syringe 6 is passed through the

vacuum collection tubes

3a, 3b, 3c and dispensed, there is a risk that the blood collection needle tube connected to the syringe 6 may be accidentally stuck in the user's finger or the like. By using the blood collection tube holder 1 shown in the above, the risk of such needle sticks can be reduced.

The female connector 15b may be provided on the protruding portion 14 separately from the needle base 15. Further, in the example shown in FIG. 11, the male screw 15b1 is provided on the outer circumference of the female connector 15b, but the male screw 15b1 may be omitted. Needless to say, the female connector 15b may be provided in either the blood collection tube holder 1 shown in FIG. 1 or the blood collection tube holder 1 shown in FIG.

FIG. 12 shows an example in which the connecting tool 7 is provided in the blood collecting kit 2 instead of the blood collecting tool 5.
