Means for Solving the Problems

[0007] The medical device support of this disclosure is a medical device support for fixing a protective tube for housing a medical device, the medical device support comprising a substantially planar base and a claw portion having one end connected to the base and the other end rising from the base and having a hole formed therein for holding the protective tube, wherein when the medical device support is housed in a bag with the protective tube inserted through the hole, the claw portion contacts the inner circumferential surface of the bag and tilts toward the base, causing the inner circumferential edge of the hole to press the protective tube toward the base. [Brief explanation of the drawing]

[Figure 4] This is a schematic front view showing the usage state of Figure 1. [Figure 5] This is a schematic side view of Figure 5. [Figure 6] This is a schematic plan view showing a second embodiment. [Figure 7] This is a schematic front view of Figure 6. [Figure 8] This is a schematic side view of Figure 6. [Figure 9] This is a partially enlarged schematic front view showing an example of the contact state between the claw portion and the bag body. [Modes for carrying out the invention]

[0009] The medical device support in this disclosure is (1) A medical device support for fixing a protective tube for housing a medical device, wherein the medical device support comprises a substantially flat base and a claw portion, one end of which is connected to the base and the other end of which rises from the base and has a hole formed therein for holding the protective tube, and when the medical device support is housed in a bag with the protective tube inserted through the hole, the claw portion contacts the inner circumferential surface of the bag and tilts toward the base, thereby causing the inner circumferential edge of the hole to press the protective tube toward the base. With this configuration, the protective tube can be securely fixed to the medical device support by the pressure exerted on the protective tube as the claw portion tilts.

[0010] (2) In the medical device support described in (1) above, the length in the direction perpendicular to the base between the end of the claw portion furthest from the base and the inner periphery of the hole furthest from the base may be 10 mm or more and 40 mm or less. With this configuration, for example, when force is applied to the tip of the claw due to contact with the bag, the claw can effectively press against the protective tube by setting the distance between the tip of the claw, which is the point of force application, and the inner circumference of the hole, which is the point of action, to the above range.

[0011] (3) In the medical device support described in (1) and (2) above, the claw portion may be arranged to make surface contact with the inner circumferential surface of the bag body. This configuration allows for a reduction in the pressure between the inner surface of the bag and the tip of the claw, even with the same frictional force. As a result, it is possible to prevent the bag from tearing or the claw from deforming.

[0012] In this specification, “tip of the claw” means the end of the claw that is furthest from the base in a direction perpendicular to the base. “Vertical state” means the state in which the claw is standing perpendicular to the base. “Tilt state” means the state in which the claw is standing at an angle to the base.

[0013] Hereinafter, the first and second embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited only to the embodiments described in the drawings. The dimensions of each part shown in the drawings are the dimensions shown for the purpose of facilitating the understanding of the implementation content, and do not necessarily correspond to the actual dimensions.

[0014] <Medical device support> [First Embodiment] Figs. 1 to 5 are schematic views showing the first embodiment. The medical device support is a device for fixing a protective tube (illustrated by the virtual line of reference numeral 2) that houses a medical device. As shown in Fig. 1, the medical device support 1 can be formed of, for example, a mount 10 including a base 11 and a claw portion 21.

[0015] The base 11 is a substantially planar portion to which one end of the claw portion 21 is connected. The base 11 constitutes at least a part of the mount 10 to which the claw portion 21 is connected.

[0016] The claw portion 21 is a portion having one end connected to the base 11 and the other end opposite to the one end standing up from the base 11. As shown in Fig. 3, a hole 21h for holding the protective tube 2 is formed in the claw portion 21.

[0017] The shape of the hole 21h is not particularly limited. In the present embodiment, a hole 21h having a circular inner peripheral edge is exemplified so that a cylindrical protective tube 2 having an annular cross section can be accommodated.

[0018] The claw portion 21 is formed to tilt toward the base portion 11. The tilting of the claw portion 21 is caused, for example, by the bag body packaging the medical device support 1 coming into contact with the tip of the claw portion 21. When the medical device support 1 is placed in the bag body 4 with the protective tube 2 inserted through the hole 21h, the claw portion 21 comes into contact with the inner circumferential surface 4s of the bag body 4 and tilts toward the base portion 11, causing the inner circumferential edge 21c of the hole 21h to press the protective tube 2 toward the base portion 11 (see Figure 4). At this time, the frictional force between the claw portion 21 and the protective tube 2 caused by the pressing fixes the protective tube 2 to the medical device support 1.

[0019] The position of the hole 21h in the claw portion 21 is not particularly limited. In the direction parallel to the base portion 11 (width direction), the hole 21h may be located in the middle. In the direction perpendicular to the base portion 11 (height direction), the hole 21h may be located in the middle, or it may be located closer to the base portion 11 than the middle (see Figure 3).

[0020] The length L in the direction perpendicular to the base 11 between the end of the claw portion 21 furthest from the base 11 and the inner circumferential edge 21c of the hole 21h furthest from the base 11 may be 10 mm or more and 40 mm or less. The length L may also be 10 mm or more and 30 mm or less. For example, when force is applied to the tip 21a of the claw portion 21 by contact with the bag body 4, by setting the length L between the tip 21a of the claw portion 21, which is the point of force application, and the inner circumferential edge 21c of the hole 21h, which is the point of application, to the above range, the claw portion 21 can effectively press against the protective tube 2.

[0021] In this embodiment, the hole 21h is positioned (L=20mm) closer to the base 11 than both the midpoint in the width direction and the midpoint in the height direction. By positioning the hole 21h closer to the base 11 than the midpoint in the height direction, the protective tube 2 can be stably held on the backing paper 10.

[0022] The base sheet 10 may include parts having a three-dimensional shape in addition to the base portion 11 and the claw portion 21. The medical device support 1 of this embodiment includes a stopper 31 and a fastening portion 41 on the base sheet 10. The stopper 31 abuts against one end of the protective tube 2, positioning the protective tube 2 at a predetermined location on the medical device support 1. The fastening portion 41 engages with the base end of the medical device 3, fixing the medical device 3 to the medical device support 1 in a detachable manner.

[0023] The material forming the backing board 10 is not particularly limited as long as it can hold the protective tube 2 and keep the medical device 3 clean. Examples of such materials include paper materials, resin materials, and synthetic paper made by mixing these. Examples of paper materials include fine paper, medium-quality paper, kraft paper, glossy kraft paper, polished kraft paper, and surface-coated paper. Examples of resin materials include polyethylene and polypropylene.

[0024] The usage of the medical device support 1 will be described. In this description, the medical device support 1 packaged in a bag 4 will be used as an example.

[0025] First, prepare the medical device support 1, protective tube 2, medical device 3, and bag 4. For example, the medical device support 1 is a cardboard base 10 having a substantially flat base 11 and a vertical claw portion 21. The protective tube 2 is a cylindrical tube. The medical device 3 is a guide wire (hereinafter also referred to as "guide wire 3").

[0026] Next, using the medical device support 1 and the protective tube 2, one end of the protective tube 2 is passed through the hole 21h of the outermost claw portion 21 of the claw portions 21 which are arranged in a roughly straight line. Then, the protective tube 2 is sequentially passed through the holes 21h of each of the remaining claw portions 21, and the protective tube 2 is positioned in the predetermined location on the medical device support 1. At this time, the positioning may also be done by bringing one end of the protective tube 2 into contact with the stopper 31.

[0027] Next, the guide wire 3 is housed in the protective tube 2. Specifically, one end of the guide wire 3 is inserted into the opening 2a of the protective tube 2, and the guide wire 3 is pushed through the lumen 2h of the protective tube 2 until it reaches a predetermined position. After that, the guide wire 3 may be fixed to the medical device support 1 by engaging the fastening part 41 provided on the medical device support 1 with the guide wire 3.

[0028] Next, the protective tube 2 is fixed to the medical device support 1 by tilting the claw portion 21 toward the base portion 11. As shown in Figure 4, for example, a bag 4 is used that is sized such that its inner circumferential surface 4s contacts the claw portion 21 when the medical device support 1 is inserted. By pressing down on the claw portion 21 while the inner circumferential surface 4s of the bag 4 abuts against the tip portion 21a of the claw portion 21, the claw portion 21 can be tilted.

[0029] As shown in Figure 5, the apparent inner diameter φ1 of the hole 21h in the direction perpendicular to the base 11 when the device is tilted is smaller than the apparent inner diameter φ2 of the hole 21h when the device is upright. Therefore, in the tilted state, the opportunity for the inner peripheral edge 21c of the hole 21h to come into contact with the outer peripheral surface of the protective tube 3 increases compared to the upright state, and the protective tube 2 is more easily pressed toward the base 11 by the inner peripheral edge 21c of the hole 21h. As a result, the frictional force between the inner peripheral edge 21c and the protective tube 2 restricts the movement of the protective tube 2 relative to the claw portion 21, and the protective tube 2 is fixed to the medical device support 1.

[0030] As described above, the medical device support 1 has the above configuration, so the protective tube 2 can be securely fixed to the medical device support 1 by the pressure on the protective tube 2 caused by the tilting of the claw portion 21.

[0031] <Medical device set> [Second Embodiment] Figures 6 to 8 are schematic diagrams showing a second embodiment. As shown in Figures 6 and 7, the medical device set 100 includes, for example, a medical device support 1, a protective tube 2, a medical device 3, and a bag 4.

[0032] The medical device support 1 is a support for fixing a protective tube 2 that houses a medical device 3. The medical device support 1 comprises a substantially planar base 11 and a claw portion 21, one end of which is connected to the base 11 and the other end of which rises from the base 11 and has a hole 21h formed therein for holding the protective tube 2. When the medical device support 1 is placed in the bag 4 with the protective tube 2 inserted through the hole 21h, the claw portion 21 contacts the inner circumferential surface 4s of the bag 4 and tilts toward the base 11, causing the inner circumferential edge 21c of the hole 21h to press the protective tube 2 toward the base 11. In this embodiment, the medical device support 1 described in detail in the first embodiment is exemplified as the medical device support.

[0033] The protective tube 2 is a component fixed to the medical device support 1. The shape of the protective tube 2 is not particularly limited as long as it can house the medical device 3 and be inserted into the hole 21h of the claw portion 21. In this embodiment, a long cylindrical protective tube 2 with an annular cross-section and an opening 2a at one end is provided as an example.

[0034] The protective tube 2 preferably has sufficient rigidity to keep the medical device 3 housed inside clean and to prevent excessive force from being applied to the medical device 3. Examples of materials for forming the protective tube 2 include polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, polyvinyl chloride, polystyrene, polyamide, and polyimide.

[0035] The medical device 3 is a component housed in the protective tube 2. The medical device 3 is not particularly limited as long as it can be housed in the protective tube 2. In this embodiment, a known guide wire 3 is exemplified as the medical device 3.

[0036] The bag 4 is a component for packaging the medical device support 1. The bag 4 is formed so that when the medical device support 1 is inserted, its inner circumferential surface 4s contacts the claw portion 21. The shape of the bag 4 is not particularly limited. For example, a rectangular bag 4 with heat-sealed on three sides other than the opening 4a may be used.

[0037] As shown in Figure 8, in the medical device set 100, the contact between the inner circumferential surface 4s of the bag body 4 and the claw portion 21 causes the claw portion 21 to tilt toward the base portion 11, and the inner circumferential edge 21c of the hole 21h presses the protective tube 2 toward the base portion 11.

[0038] The contact between the bag body 4 and the claw portion 21 may be point contact, line contact, or surface contact. As shown in Figure 9, for example, if the tip portion 21a of the claw portion 21 is positioned to make surface contact with the inner circumferential surface 4s of the bag body 4, the pressure between the inner circumferential surface 4s of the bag body 4 and the tip portion 21a of the claw portion 21 can be reduced even with the same frictional force. As a result, it is possible to prevent the bag body 4 from tearing or the claw portion 21 from deforming.

[0039] The medical device set 100 can be formed using the same procedure as described in the first embodiment for the use of the medical device support 1. A detailed explanation is omitted here. As shown in Figure 7, after the protective tube 2 is fixed to the medical device support 1, the bag 4 may be sealed by heat-sealing the opening 4a.

[0040] As described above, the medical device set 100 has the above configuration, so the protective tube 2 can be securely fixed to the medical device support 1 by the pressure on the protective tube 2 caused by the tilting of the claw portion 21.

[0041] This disclosure is not limited to the configurations of the embodiments described above, but is intended to include all modifications within the meaning and scope of the claims as indicated by the claims. Some of the configurations of the embodiments described above may be deleted or replaced with other configurations, or other configurations may be added to the configurations of the embodiments described above.

[0042] In the embodiments described above, a cylindrical protective tube 2 was exemplified as the protective tube 2 to be fixed. The protective tube 2 is not particularly limited as long as it can be fixed to the medical device support 1. The protective tube 2 may have a cross-sectional shape other than circular, such as an elliptical or polygonal shape. In such cases, the shape of the hole 21h of the claw portion 21 can be determined to match the lateral shape of the protective tube 2.

[0043] In the embodiment described above, a guidewire was exemplified as the medical device 3 to be housed. The medical device is not particularly limited as long as it can be housed in the protective tube. Examples of medical devices include catheters, dilators, Y-connectors, etc.

[0044] In the embodiments described above, a configuration was described in which a protective tube 2 housing the medical device 3 is fixed to the medical device support 1. The medical device support may directly fix the medical device without using a protective tube. In such a configuration of the medical device support, the term "protective tube" in this specification described above can be replaced with "long medical device." Specific examples of long medical devices to which this can be replaced include, for example, well-known long medical instruments such as guide wires, catheters, dilators, and Y-connectors.

[0045] In a medical device support for securing long medical devices, by providing a claw portion that tilts toward the base, the protective tube can be fixed to the medical device support by the pressure of the protective tube on the inner periphery of the hole. As a result, it is possible to suppress the long medical device from shifting relative to the medical device support or from falling off the medical device support.
