Summary of the Invention

Problems to be Solved by the Invention

[0006] However, while the holder body is made of resin like other medical instruments, in the blood collection tube holder described in Patent Document 1 above, since the fixing portion is configured to be thin, the fixing portion is likely to be deformed (elastically deformed and plastically deformed), and the fixing of the adapter may become unstable.

[0007] In view of these circumstances, the present invention aims to provide a blood collection tube holder that can stably fix an adapter connected to a blood collection tube. [Means for solving the problem]

[0008] The blood collection tube holder of the present invention is configured as a bottomed cylindrical shape having a bottom at the tip end, and comprises a holder body that accommodates at least a portion of a blood collection tube, a cylindrical fixing part provided at the bottom and into which an adapter connected to the blood collection tube is inserted and fixed, an outer wall part provided on the outer circumference of the fixing part, and a part disposed between the fixing part and the outer wall part. , provided intermittently in the circumferential direction of the fixed portion It is characterized by comprising a connecting part.

[0009] According to the blood collection tube holder of the present invention, deformation of the fixing part can be suppressed by the outer wall, so that the adapter connected to the blood collection tube can be stably fixed. In other words, since the fixing part can be supported by the outer wall via the connection part, the fixing part is less likely to deform when fixing the adapter to the holder body, and even when external force is applied to the adapter after it has been fixed, so that the adapter can be stably fixed to the holder body.

[0010] Furthermore, in the blood collection tube holder of the present invention, it is preferable that the connecting portion is integrally provided with at least one of the bottom portion, the fixing portion, and the outer wall portion.

[0011] According to this, the connecting part can be formed simultaneously with the holder body, allowing the connecting part to be constructed at low cost and easily, and the fixing part to be reliably supported by the outer wall.

[0013] According to this, by adjusting the range occupied by the connection part 15 in the circumferential direction, the amount of deformation of the fixing part 13 can be appropriately set, thereby enabling the adapter to be fixed more stably. Furthermore, even when the holder body and the connection part are integrally molded in resin, the fixing part and its vicinity can be made thinner, thereby preventing molding defects such as sink marks and voids, improving the shape accuracy of the fixing part and its vicinity, and enabling the adapter to be fixed more stably.

[0014] Furthermore, in the blood collection tube holder of the present invention, it is preferable that the outer wall portion is configured in a cylindrical shape that surrounds the fixing portion from the outer periphery.

[0015] This allows for increased rigidity of the outer wall section, enabling more secure support of the fixing point, and thus allowing the adapter to be fixed more stably. [Effects of the Invention]

[0016] According to the present invention, it is possible to achieve the excellent effect of stably fixing the adapter connected to the blood collection tube. [Brief explanation of the drawing]

[0017] [Figure 1] A is a plan view of a blood collection tube holder according to one embodiment of the present invention. B is a front view of the blood collection tube holder. [Figure 2] This is a cross-sectional view taken along line II in Figure 1A. [Figure 3] A is a plan view of the holder body. B is a cross-sectional view taken along line II-II in Figure 3A, partially showing the area around the fixing part, outer wall part, and connecting part. [Figure 4] Figures A through C show modified versions of the blood collection tube holder. [Figure 5] Figures A and B show modified versions of the blood collection tube holder. [Modes for carrying out the invention]

[0018] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0019] FIG. 1A is a plan view of a blood collection tube holder 1 according to an embodiment of the present invention, and FIG. 1B is a front view of the blood collection tube holder 1. Further, FIG. 2 is a cross-sectional view taken along line I-I of FIG. 1A. In these figures, a state where an adapter 100 is attached to the blood collection tube holder 1 is shown.

[0020] The blood collection tube holder 1 is composed of a holder main body 10 that houses at least a part of a blood collection tube (not shown) and a holding member 20 that holds the blood collection tube inside the holder main body 10.

[0021] The holder main body 10 is configured in a bottomed cylindrical shape composed of a bottom portion 11 on the tip side (upper side in FIGS. 1B and 2) and a cylindrical portion 12 on the rear end side (lower side in FIGS. 1B and 2). A through hole 11a is provided in the central portion of the bottom portion 11, and a cylindrical fixing portion 13 and an outer wall portion 14 that project toward the tip side from the tip surface 11b are provided. And a connecting portion 15 is provided between the fixing portion 13 and the outer wall portion 14.

[0022] The fixing portion 13 is a portion where the adapter 100 is inserted and fixed from the tip side, and the outer wall portion 14 is a portion for protecting the fixing portion 13. And the connecting portion 15 is a portion for reinforcing the fixing portion 13 by connecting the fixing portion 13 and the outer wall portion 14 and utilizing the outer wall portion 14. Details of the fixing portion 13, the outer wall portion 14, and the connecting portion 15 will be described later.

[0023] On the outer peripheral side of the rear end surface 11c of the bottom portion 11, a plurality (four in this embodiment) of tongue-shaped protruding pieces 11c1 are provided. The tongue-shaped protruding pieces 11c1 are configured in a substantially flat plate shape that protrudes toward the rear end side, and by elastically deforming in contact with the holding member 20, they are for reinforcing the holding force of the holding member 20.

[0024] ​Furthermore, several (four in this embodiment) contact portions 11c2 are provided slightly axially towards the tongue-shaped projection 11c1 on the rear end surface 11c. These contact portions 11c2 are provided so as to protrude toward the rear end and are intended to position the blood collection tube in the axial direction by contacting the tip surface of the blood collection tube.

[0025] The tip portion of the cylindrical section 12 protrudes further forward than the bottom portion 11. In other words, the bottom portion 11 is offset to the rear end of the cylindrical section 12. In this embodiment, this configuration improves ease of handling while shortening the overall axial length of the holder body 10.

[0026] The outer circumferential surface 12a of the cylindrical portion 12 is configured in a stepped shape in which the outer diameter expands in two stages toward the rear end. In addition, the outer circumferential surface 12a is provided with a plurality (six in this embodiment) of anti-slip ribs 12a1 that extend in the axial direction (vertical direction in Figures 1B and 2).

[0027] The rear end of the cylindrical portion 12 is provided with a flange 16 that is elliptical in plan view. This flange 16 is for the user to grip with their fingers when inserting the blood collection tube into the holder body 10, and the tip surface 16a is provided with a crescent-shaped anti-slip recess 16a1. In addition, the front and rear ends of the flange 16 are provided with side wall portions 16b that protrude toward the tip, improving the ease with which the holder body 10 can be held when removing the blood collection tube from inside the holder body 10.

[0028] The inner circumferential surface 12b of the cylindrical portion 12 is provided with a first recess 12b1 that is continuous in the circumferential direction at the rear end, and a plurality (four in this embodiment) of groove-shaped second recesses 12b2 that extend axially from the first recess 12b1 toward the front end. The first recess 12b1 is the portion into which the retaining member 20 is fitted, and the second recesses 12b2 are portions that avoid interference between the retaining member 20 and the tongue-shaped projection 11c1.

[0029] The leading edge of the inner circumferential surface 12b is further provided with a plurality (eight in this embodiment) of contact ribs 12b3 that extend axially from the bottom 11 toward the rear end. These contact ribs 12b3 are for positioning the blood collection tube radially by contacting it radially.

[0030] The contact rib 12b3 is provided with a stepped portion 12b4 that contacts the tip surface of a blood collection tube (a type that does not contact the contact portion 11c2) to position the blood collection tube in the axial direction. In addition, half of the contact ribs 12b3 are provided with a projection 12b5 at the rear end that engages with the flange-like portion of the blood collection tube to restrict its movement toward the rear end.

[0031] The retaining member 20 is composed of a cylindrical fitting portion 21 and a plurality (four in this embodiment) of pressure contact portions 22 that protrude from the fitting portion 21 toward the tip. The fitting portion 21 is the part that fits into the first recess 12b1 of the holder body 10. Positioning protrusions 21a are provided at four locations on the outer circumferential surface of the fitting portion 21. The retaining member 20 is positioned in the circumferential direction by having these positioning protrusions 21a housed in positioning recesses 12b6 provided within the first recess 12b1.

[0032] The contact portion 22 is configured as a strip-shaped plate that extends diagonally from the fitting portion 21 toward the tip, gradually approaching the axis, then bends and extends slightly away from the axis. The contact portion 22 contacts the blood collection tube inserted into the holder body 10 in the radial direction and elastically deforms to swing toward the outer circumference, and also elastically deforms so that the bent portion opens when the tip contacts the tongue-shaped projection 11c1.

[0033] The restoring force of the elastic deformation of the pressure contact portion 22 causes the blood collection tube inside the holder body 10 to be pressed radially, thereby holding it in the blood collection tube holder 1. In this embodiment, the restoring force of the elastic deformation of the tongue-shaped projection 11c1 is also added to the blood collection tube, making it possible to hold the blood collection tube more stably.

[0034] The holder body 10 and the retaining member 20 are made of a suitable transparent or translucent resin, such as polypropylene or polycarbonate.

[0035] The adapter 100 consists of a tubular connecting needle tube 101 having a sharp needle tip at its end, a stepped cylindrical hub 102 fixed to the base end of the connecting needle tube 101, and an elongated bottomed cylindrical sleeve 103 fixed to the hub while covering the connecting needle tube 101.

[0036] The connecting needle tube 101 is the part that is inserted into the rubber stopper of the blood collection tube, and is made of a suitable metal such as stainless steel. The base end of the connecting needle tube 101 is fixed to the rear end of the hub 102 with adhesive.

[0037] The hub 102 is the part that is fixed to the holder body 10, and like the holder body 10, it is made of a suitable resin such as polyvinyl chloride or polypropylene. The rear end of the hub 102 is provided with a male screw 102a for fixing to the holder body 10. The tip of the male screw 102a is provided with a flange portion 102b for positioning relative to the holder body 10.

[0038] In this embodiment, the threads of the male screw 102a are divided into four sections in the circumferential direction, leaving a portion at the rear end, and are provided intermittently. Furthermore, a notch (not shown) is provided in the flange portion 102b to allow ventilation between the holder body 10 and the adapter 100. In this way, even when the adapter 100 is attached to the holder body 10, sterilization gas (such as steam or ethylene oxide gas) can be introduced between the fixing portion 13 and the male screw 102a, making the sterilization process more efficient.

[0039] The tip of the hub 102 is provided with a male connector 102c that conforms to standards such as ISO80369-7, and the blood collection needle tube that is inserted into the body is connected to the adapter 100 via this male connector 102c.

[0040] The sleeve 103 is a part that covers and protects the portion of the connecting needle tube 101 that protrudes from the hub 102, and is made of a suitable elastic material with flexibility, such as isoprene rubber. The sleeve 103 is fixed to the hub 102 by locking onto the rear end of the hub 102, which is press-fitted into the opening, by the restoring force of elastic deformation.

[0041] The adapter 100 is fixed to the holder body 10 with the tip of the connecting needle tube 101, which is directed towards the rear end, positioned inside the holder body 10. Therefore, the user of the blood collection tube holder 1 can connect the blood collection tube to the adapter 100 simply by inserting the tip of the blood collection tube, which is equipped with a rubber stopper, into the holder body 10 from the rear end, thereby passing the sleeve 103 and rubber stopper through the connecting needle tube 101.

[0042] By passing the rubber stopper or the like of the blood collection tube through the connecting needle tube 101 and connecting the blood collection tube and the adapter 100, the inside of the blood collection tube and the inside of the male connector 102c are connected, and as a result the blood collection needle tube connected to the male connector 102c is connected to the inside of the blood collection tube. In other words, the blood sample collected from the blood collection needle tube flows into the blood collection tube and is stored there. Generally, the inside of the blood collection tube is depressurized beforehand, and the blood is drawn into the blood collection tube by the negative pressure.

[0043] When the blood collection tube and adapter 100 are connected, the sleeve 103 is compressed axially between the blood collection tube and the hub 102. However, when the blood collection tube is removed from the adapter 100, it returns to its original shape that covers the connecting needle tube 101.

[0044] The adapter 100 may also be equipped with a female connector to which the tip of a syringe can be connected, instead of the male connector 102c, or it may be equipped with a blood collection needle tube. Furthermore, the adapter 100 may be connected to the male connector 102c, the female connector, or the blood collection needle tube via a flexible tube or the like. In addition, the male thread 102a may be provided continuously.

[0045] Next, the fixing portion 13, the outer wall portion 14, and the connecting portion 15 will be described. Figure 3A is a plan view of the holder body 10, and Figure 3B is a cross-sectional view taken along line II-II of Figure 3A, partially showing the area around the fixing portion 13, the outer wall portion 14, and the connecting portion 15. As described above, the fixing portion 13 and the outer wall portion 14 are each cylindrical in shape and are arranged substantially coaxially.

[0046] The inner circumferential surface 13a of the fixing portion 13 is provided with a female thread 13b that engages with the male thread 102a of the adapter 100. In other words, the adapter 100 is fixed to the holder body 10 when the hub 102 is inserted into the fixing portion 13 and the male thread 102a and female thread 13b engage.

[0047] Furthermore, the male screw 102a and the female screw 13b are composed of two threads. In this embodiment, the female screw 13b is composed of two threads that do not overlap when viewed from the axial direction, thereby simplifying the mold structure of the holder body 10.

[0048] The tip surface 13c of the fixing portion 13 abuts against the flange portion 102b to position the adapter 100 relative to the holder body 10. In addition, a tapered portion 13d is provided on the tip side of the inner circumferential surface 13a of the fixing portion 13 of the hub 102, with an inner diameter that gradually increases toward the tip, in order to facilitate the insertion of the adapter 100.

[0049] The outer wall portion 14 is provided so as to surround the fixing portion 13 from the outer circumference, and its inner diameter is set to be larger than the outer diameter of the fixing portion 13. Therefore, a predetermined radial gap is provided between the inner circumferential surface 14a of the outer wall portion 14 and the outer circumferential surface 13e of the fixing portion 13. Furthermore, the inner diameter of the outer wall portion 14 is set to be slightly larger than the outer diameter of the flange portion 102b of the hub 102, and the axial dimension of the outer wall portion 14 is set to be larger than that of the fixing portion 13. Therefore, when the adapter 100 is fixed to the holder body 10, the flange portion 102b is housed within the outer wall portion 14.

[0050] In this embodiment, since ventilation is provided between the holder body 10 and the adapter 100, the outer wall portion 14 is provided to prevent contact of fingers or connectors with the fixing portion 13, thereby protecting the fixing portion 13 and the adapter 100 from damage or contamination. In other words, it prevents damage to the fixing portion 13 or the adapter 100 by something getting caught in the step or ventilation gap between the fixing portion 13 and the adapter 100, and prevents contaminants from entering the gap between the fixing portion 13 and the adapter 100 and adhering to the connecting needle tube 101 or blood collection tube, etc.

[0051] Furthermore, although not shown in the diagram, by providing the outer wall portion 14, the protective cap for the male connector 102c (or the blood collection needle tube provided by the adapter 100) can be fixed to the outer wall portion 14 instead of the hub 102, thus making it possible to more reliably protect the male connector 102c from damage or contamination. Also, by fixing the cap to the outer wall portion 14, the gap between the holder body 10 and the adapter 100 can be sealed, so contamination of the connecting needle tube 101 and sleeve 103 can be more reliably prevented.

[0052] The connecting portion 15 is positioned to connect the fixing portion 13 and the outer wall portion 14. In this embodiment, four rib-shaped connecting portions 15, which are integrally formed with the fixing portion 13 and the outer wall portion 14, are arranged at approximately equal intervals (i.e., approximately 90° intervals) in the circumferential direction. Furthermore, the connecting portions 15 in this embodiment are provided to extend from the tip surface 11b of the bottom portion 11 toward the tip side in the axial direction of the fixing portion 13 and the outer wall portion 14 (i.e., the holder body 10), and are integrally formed with the bottom portion 11.

[0053] In this embodiment, the fixing portion 13 is supported by the outer wall portion 14 via the connecting portion 15, thereby suppressing deformation (elastic deformation and plastic deformation) of the fixing portion 13. Specifically, by supporting the fixing portion 13 from the outer circumference with the highly rigid cylindrical outer wall portion 14, deformation that would cause the inner and outer diameters of the fixing portion 13 to expand, and deformation that would cause the fixing portion 13 to tilt with respect to the axis of the holder body 10 are suppressed.

[0054] This makes it possible to stably fix the adapter 100 to the holder body 10. Specifically, by suppressing deformation of the fixing part 13, it is possible to prevent situations such as the adapter 100 being forcibly screwed into the holder body 10 at an angle. In other words, since the adapter 100 can be fixed to the holder body 10 in the correct posture, it becomes possible to properly puncture the blood collection tube inserted into the holder body 10 with the connecting needle tube 101 and connect it properly.

[0055] Furthermore, even when an external force is applied that causes the adapter 100 to tilt relative to the holder body 10, such as when puncturing the needle tube 101 for connecting to a blood collection tube or when puncturing the body with a blood collection needle tube connected to the male connector 102c, it is possible to suppress the tilting of the adapter 100.

[0056] Furthermore, even when the male screw 102a and female screw 13b are brought into contact in such a way that they undergo appropriate elastic deformation to provide a loosening prevention effect through friction, it is possible to increase the restoring force of the elastic deformation in the fixing part 13 to ensure that the loosening prevention effect is reliably achieved. In other words, it is possible to prevent the adapter 100 from wobbling or falling off due to loosening of the engagement between the male screw 102a and the female screw 13b.

[0057] In this embodiment, the connecting portion 15 is positioned between the fixing portion 13 and the outer wall portion 14, thereby suppressing deformation of the fixing portion 13 and stably fixing the adapter 100 to the holder body 10. This prevents malfunctions that may occur when using the blood collection tube holder 1. As a result, the blood collection tube holder 1 can be used safely.

[0058] Furthermore, in this embodiment, the connecting portion 15 is provided integrally with the fixing portion 13, the outer wall portion 14, and the bottom portion 11 (by integrally resin molding), which not only reliably supports the fixing portion 13 but also enables low-cost and easy placement of the connecting portion 15.

[0059] Furthermore, in this embodiment, by providing the connecting portion 15 intermittently in the circumferential direction, it is prevented that the area near the fixing portion 13 becomes thicker even while the connecting portion 15 is provided. As a result, in this embodiment, molding defects such as sink marks and voids that may occur in the thickened portion during resin molding are prevented, and the shape accuracy of the fixing portion 13 and the female screw 13b can be improved, making it possible to stably fix the adapter 100 by the holder body 10.

[0060] Furthermore, by providing the connecting portion 15 intermittently in the circumferential direction, it is possible to adjust the range occupied by the connecting portion 15 in the circumferential direction and appropriately set the amount of deformation of the fixing portion 13. As a result, in this embodiment, not only is the fixing of the adapter 100 made more stable, but even when the female screw 13b is intended to have an anti-loosening effect, it is possible to prevent the engagement with the male screw 102a from becoming excessively tight.

[0061] In this embodiment, the axial length of the connecting portion 15 is set to approximately 73% of the axial length of the fixing portion 13. However, the axial length of the connecting portion 15 is not limited to this, and may be longer than, for example, the axial length of the fixing portion 13. The amount of deformation of the fixing portion 13 can also be appropriately set by adjusting the axial length of the connecting portion 15.

[0062] Next, a modified example of the blood collection tube holder 1 will be described. Figures 4A-C and 5A and 5B show modified examples of the blood collection tube holder 1, and are cross-sectional views taken along line II-II of Figure 3A, partially showing the area around the fixing part 13, the outer wall part 14, and the connecting part 15.

[0063] Figure 4A shows an example where the connecting portion 15 is integrally provided with only the outer wall portion 14 and the bottom portion 11, Figure 4B shows an example where the connecting portion 15 is integrally provided with only the fixing portion 13 and the bottom portion 11, and Figure 4C shows an example where the connecting portion 15 is integrally provided with only the bottom portion 11.

[0064] In this way, by providing a gap between the connecting portion 15 and the fixing portion 13, and between the connecting portion 15 and the outer wall portion 14, or both, it becomes possible to ensure that the fixing portion 13 is supported by the outer wall portion 14 after it has deformed to some extent and come into contact with the connecting portion 15 and the outer wall portion 14 or the fixing portion 13.

[0065] In other words, since the fixing part 13 can be allowed to deform freely to a predetermined extent, depending on the configuration of the parts of the adapter 100 and the fixing part 13 that engage with each other (here, the male screw 102a and the female screw 13b), it becomes possible to make the fixing of the adapter 100 to the holder body 10 easier or more stable. Also, depending on the configuration of the holder body 10 or the adapter 100, the blood collection tube holder 1 can be made easier to use by allowing the bending of the fixing part 13 to a predetermined extent.

[0066] Although not shown in the illustrations, a gap may be provided between the connecting portion 15 and the bottom portion 11 in the examples shown in Figures 4A and 4B. That is, the connecting portion 15 may be integrally provided only with the outer wall portion 14, or integrally provided only with the fixing portion 13. Also, in the examples shown in Figures 3A and 3B, a gap may be provided between the connecting portion 15 and the bottom portion 11. That is, the connecting portion 15 may be integrally provided only with the fixing portion 13 and the outer wall portion 14.

[0067] Since the connecting portion 15 can be formed during the resin molding of the holder body 10 as long as it is integrally provided with at least one of the fixing portion 13, the outer wall portion 14, or the bottom portion 11, the connecting portion 15 can be provided at low cost and easily.

[0068] Furthermore, the number of connecting parts 15 is not particularly limited, and any number can be used. Also, the shape of the connecting parts 15 is not particularly limited, and they may be provided continuously in the circumferential direction, or intermittently in the axial direction. Also, the connecting parts 15 may be arranged at unequal intervals, or they may be arranged in a staggered pattern, for example. In addition, the connecting parts 15 shown in Figures 3A and 3B, and Figures 4A to 4C may be combined as appropriate. In other words, the number, shape, and arrangement of the connecting parts 15 are not particularly limited, and any number, shape, and arrangement can be used.

[0069] Figures 5A and 5B show an example in which the connecting portion 15 is configured separately from the holder body 10. In this example, the connecting portion 15 is made of a cylindrical member and is fixed to the holder body 10 by press-fitting it from the tip side between the fixing portion 13 and the outer wall portion 14.

[0070] In this case, although it becomes necessary to provide a separate process for attaching the connecting part 15 in the manufacturing of the blood collection tube holder 1, the fixing part 13 and the outer wall part 14 can be made into a simple shape, which makes it possible to simplify the mold for the holder body 10 and reduce costs.

[0071] The connection portion 15 may be fixed to the holder body 10 by other methods, such as engagement, ultrasonic welding, or adhesive bonding. Furthermore, the shape of the connection portion 15 is not particularly limited and may be rectangular, spiral, or otherwise, and may have protrusions on its outer or inner surfaces.

[0072] Furthermore, the material of the connecting portion 15 is not particularly limited and may be the same resin as the holder body 10, or it may be a different resin, metal, etc. Alternatively, the connecting portion 15 may be constructed by pouring an adhesive or UV-curing resin between the fixing portion 13 and the outer wall portion 14 and allowing it to harden.

[0073] Furthermore, while the examples shown in Figures 5A and 5B show a case where a gap is provided between the connecting portion 15 and the bottom portion 11, a gap may also be provided between the connecting portion 15 and the fixing portion 13, or between the connecting portion 15 and the outer wall portion 14, or no gap may be created at all between the connecting portion 15 and the bottom portion 11, the fixing portion 13, and the outer wall portion 14.

[0074] Furthermore, the connecting portion 15 may also be provided on the adapter 100. That is, the connecting portion 15 may be positioned between the fixing portion 13 and the outer wall portion 14 when fixing the adapter 100 to the holder body 10. In this case, the connecting portion 15 may be provided integrally with the hub 102, etc., or it may be provided separately. Alternatively, a connecting portion 15 that is configured separately from the holder body 10 may be provided in combination with a connecting portion 15 that is provided integrally with the holder body 10.

[0075] Although not shown in the illustrations, the fixing portion 13 and the outer wall portion 14 may be configured in shapes other than cylindrical, such as an elliptical tube or a rectangular tube. Furthermore, the fixing portion 13 and the outer wall portion 14 may be provided so as to protrude from the bottom portion 11 toward the rear end, or so as to protrude toward both the front and rear ends. Additionally, the fixing portion 13 and the outer wall portion 14 may have notches, windows, or the like.

[0076] Furthermore, the outer wall portion 14 is not limited to a cylindrical shape, but may be provided intermittently in the circumferential direction. Also, projections or the like that that engage with the flange portion 102b may be provided on the outer wall portion 14 to further stabilize the fixing of the adapter 100. In addition, the fixing of the adapter 100 to the fixing portion 13 is not limited to the engagement of the male screw 102a and the female screw 13b, but may be done by other engagement structures.

[0077] Although embodiments of the present invention have been described above, the blood collection tube holder of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.

[0078] For example, the shape and arrangement of each part of the blood collection tube holder 1 are not limited to the shapes and arrangements shown in the embodiments described above, and various known shapes and arrangements can be adopted. Furthermore, the blood collection tube holder 1 may not have a holding member 20, and the holder body 10 may directly hold the blood collection tube. Also, the holder body 10 may not have a tongue-shaped projection 11c1, a contact portion 11c2, a second recess 12b2, or a contact rib 12b3, etc.
