[0009] The medical device support in this disclosure is (1) 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, wherein the claw portion has a hole through which the protective tube is inserted and a movable portion arranged to surround the hole and elastically deformable so that the hole expands radially outward when pressed when the protective tube is inserted. In this configuration, the protective tube is pressed against the claw portion by the elastic force (reaction force) that causes the hole, which has been widened as the protective tube is inserted, to return to its original shape. As a result, the protective tube can be fixed to the medical device support.

[0010] (2) In the medical device support described in (1) above, the movable part may have at least one slit that starts from the periphery of the hole and extends radially with respect to the center of the hole. This configuration allows for easy creation of movable parts.

[0011] (3) In the medical device support described in (2) above, the movable part may have a plurality of cuts, and the plurality of cuts may be arranged at equal intervals along the periphery of the hole. This configuration allows the protective tube to be held isotropically and securely fixed to the medical device support.

[0012] (4) In the medical device support described in (1) above, the movable part may be made of a member that can be deformed radially outward. This configuration allows for easy creation of movable parts.

[0013] Other medical device supports in this disclosure are (5) 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, wherein the claw portion has an elastically deformable movable part including a slit that opens when pressed to insert the protective tube. With this configuration, the protective tube can be secured to the medical device support by the movable part around the hole formed by the opening.

[0014] In this specification, "radial direction" refers to the radial direction relative to the center of the hole in the claw portion in a side view (see, for example, Figure 2).

[0015] Hereinafter, the first to fourth 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 understanding of the implementation content, and do not necessarily correspond to the actual dimensions.

[0016] <Medical device support> [First Embodiment] FIGS. 1 and 2 are schematic views showing the first embodiment. The medical device support 1A is a device for fixing a protective tube 2 (illustrated by a virtual line of reference numeral 2) that houses the medical device 3. As shown in FIGS. 1 and 2, the medical device support 1A can be formed, for example, by a mount 10A including a base portion 11 and a claw portion 21.

[0017] The base portion 11 is a substantially planar portion to which one end of the claw portion 21 is connected. The base portion 11 constitutes at least a part of the mount 10A to which the claw portion 21 is connected.

[0018] The claw portion 21 is a portion where one end is connected to the base portion 11 and the other end stands up from the base portion 11. As shown in FIG. 2, the claw portion 21 has a hole 21h and a movable portion 211. <CO

[0019] The hole 21h is a portion through which the protective tube 2 is inserted. The shape of the hole 21h is not particularly limited. Examples of the shape of the inner peripheral edge of the hole 21h in a side view of the claw portion 21 include a circle, an ellipse, a polygon, etc. In the present embodiment, a hole 21h having a circular inner peripheral edge is exemplified so that a cylindrical (cross-sectional shape is an annular shape) protective tube 2 can be housed. [[ID=X]] [[ID=Y]]

[0020] [[ID=Z]] The movable portion 211 is disposed so as to surround the hole 21h, and is a portion that elastically deforms so that the hole 21h expands radially outward due to the pressing when the protective tube 2 is inserted. The hole 21h is provided on the radially inner side of the movable portion 211.

[0021] By providing such an elastically deformable movable part 211, the protective tube 2 is pressed against the claw portion 21 by the elastic force (reaction force) of the hole 21h, which is expanded when the protective tube 2 is inserted, trying to return to its original state. As a result, the protective tube 2 can be fixed to the medical device support 1. In addition, the elastic deformation of the movable part 211 improves the workability when inserting the protective tube 2 into the hole 21h.

[0022] The shape of the movable part 211 is not particularly limited. For example, the movable part 211 may be made of an elastically deformable member and have at least one slit 211a that starts from the periphery of the hole 21h and extends radially toward the center 21c of the hole. This makes it easy to form the movable part 211.

[0023] The movable part 211 has a plurality of slits 211a, which may be arranged at equal intervals along the periphery of the hole 21h. In other words, the plurality of slits 211a may be arranged symmetrically along the line or along the axis in a side view of the claw part 21. This allows the protective tube 2 to be pressed isotropically and the protective tube 2 to be stably fixed to the medical device support 1A. In this embodiment, the movable part 211 has six slits 211a, which are arranged symmetrically along the periphery of the hole 21h at 60° intervals around the center 21c of the hole 21h.

[0024] The movable part 211 may be formed integrally with the other parts of the claw portion 21, or it may be formed separately. If the entire claw portion 21 is formed integrally, the material forming the backing 10A can be an elastically deformable material (elastic material).

[0025] The base sheet 10A may include parts having a three-dimensional shape in addition to the base portion 11 and the claw portion 21. The medical device support 1A of this embodiment includes a stopper 31 and a fastening portion 41 on the base sheet 10A. 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 1A. The fastening portion 41 engages with the base end of the medical device 3, fixing the medical device 3 to the medical device support 1A in a detachable manner.

[0026] The material used to form the base 10A 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. When the entire claw portion 21, including the movable portion 211, is formed as a single unit, an elastic material is used as the material for the base 10A.

[0027] The usage of the medical device support 1A will be explained. The explanation will be given using a medical device support 1A as an example, which uses a cylindrical tube as the protective tube 2 and houses a guide wire (hereinafter also referred to as "guide wire 3") as the medical device 3.

[0028] First, prepare the medical device support 1A. Specifically, prepare a base 10A having a substantially flat base 11 and, for example, a plurality of claw portions 21 that stand vertically from the base 11. Next, pass one end of the protective tube 2 through the hole 21h of the outermost claw portion 21 of the claw portions 21 that are arranged in a substantially straight line. Then, sequentially pass the protective tube 2 through the holes 21h of the remaining claw portions 21, positioning the protective tube 2 in a predetermined position on the medical device support 1A. At this time, positioning may be done by bringing one end of the protective tube 2 into contact with the stopper 31. When inserting the protective tube 2 through the claw portion 21, the movable portion 211 is pressed and expanded by the outer surface of the protective tube 2 toward the radially outward direction of the hole 21h. At this time, a reaction force (elastic force) of the movable portion 211 is applied to the outer surface of the protective tube 2. This reaction force fixes the protective tube 2 to the claw portion 21.

[0029] 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 1A by engaging the fastening part 41 provided on the medical device support 1A with the guide wire 3.

[0030] As described above, the medical device support 1A has the above configuration, and the protective tube 2 is pressed against the claw portion 21 by the elastic force (reaction force) of the hole 21h, which is expanded when the protective tube 2 is inserted, trying to return to its original state. As a result, the protective tube 2 can be fixed to the medical device support 1A, and it is possible to prevent the protective tube 2, which houses the medical device 3, from shifting relative to the medical device support 1A or falling out of the medical device support 1A.

[0031] In the embodiment described above, a medical device support 1A in which the movable part 211 has a plurality of slits 211a was described. The number of slits 211a may be one. Even with such a configuration, the hole can be expanded and the protective tube can be fixed to the medical device support.

[0032] In the embodiment described above, a medical device support 1A was described in which the slit 211a is closed when the protective tube 2 is not inserted through the hole 21h. As shown in Figure 3, the slit 211b may be open when the protective tube is not inserted through the hole 21h.

[0033] [Second Embodiment] Figure 4 is a schematic diagram showing a second embodiment. As shown in Figure 4, the medical device support 1B can be formed from a base 10B including, for example, a base 11 and a claw portion 22. The medical device support 1B of this embodiment differs from the first embodiment in the configuration of the claw portion 22. The configuration of the base 11 and the configuration of the claw portion 22 other than those described below are the same as in the first embodiment. Therefore, the same parts are denoted by the same reference numerals and their detailed descriptions are omitted.

[0034] The claw portion 22 is a part that has a hole 22h through which the protective tube 2 is inserted, and a movable portion 221 that is arranged to surround the hole 22h and is elastically deformable so that the hole 22h expands radially outward due to the pressure applied when the protective tube 2 is inserted.

[0035] The movable part 221 is formed of a member that can be deformed radially outward. The movable part 221 may be formed of, for example, an elastically deformable thin film member. When the protective tube 2 is inserted into the hole 22h, the protective tube 2, which is in contact with the inner periphery of the hole 22h, pushes the movable part 221 outward, and the elastic force of the movable part 221 can press the protective tube 2. This fixes the protective tube 2 to the medical device support 1B.

[0036] The movable part 221 may be formed separately from the other parts of the claw portion 22. Examples of materials for forming the movable part 221 include rubber materials such as silicone rubber, isoprene rubber, butadiene rubber, chloroprene rubber, and natural rubber.

[0037] The material and thickness used for the movable part 221, as well as the inner diameter of the hole 22h, can be determined by the outer diameter of the protective tube 2 to be inserted, the surface condition such as slip resistance, etc.

[0038] The usage of the medical device support 1B will be described below. Here, only the differences from the usage of the first embodiment will be described.

[0039] First, prepare the medical device support 1B. Specifically, prepare a base 10B having multiple claw portions 22. Next, pass one end of the protective tube 2 through the hole 22h of the outermost claw portion 22. Then, sequentially pass the protective tube 2 through the holes 22h of the remaining claw portions 22, positioning the protective tube 2 in the predetermined location on the medical device support 1B. When inserting the protective tube 2 into the claw portion 22, the movable portion 221 is pressed and expanded by the outer surface of the protective tube 2 towards the radially outward direction of the hole 22h. At this time, a reaction force (elastic force) from the movable portion 221 is applied to the outer surface of the protective tube 2. This reaction force fixes the protective tube 2 to the claw portion 22.

[0040] As described above, the medical device support 1B has the above configuration, and the protective tube 2 can be fixed to the medical device support 1B by the movable part 221 around the expanded hole 22h. As a result, it is possible to prevent the protective tube 2, which houses the medical device 3, from shifting relative to the medical device support 1B or falling off from the medical device support 1B.

[0041] The medical device support 1B has a claw portion 22 positioned to surround the hole 22h, and a movable portion 221 that is elastically deformable so that the hole 22h expands radially outward due to the pressure applied when inserting the protective tube 2. Therefore, the movable portion 221 can be easily formed using an elastically deformable material.

[0042] [Third Embodiment] Figure 5 is a schematic diagram showing a third embodiment. As shown in Figure 5, the medical device support 1C can be formed from a base 10C including, for example, a base 11 and a claw portion 23. The medical device support 1C of this embodiment differs from the first embodiment in the configuration of the claw portion 23. The configuration of the base 11 and the configuration of the claw portion 23 other than those described below are the same as in the first embodiment. Therefore, the same reference numerals are used for the same parts and their detailed descriptions are omitted.

[0043] The claw portion 23 is a part that has one end connected to the base portion 11 and the other end rising up from the base portion 11. In this embodiment, the claw portion 23 has a movable portion 231.

[0044] The movable part 231 is an elastically deformable portion that includes a slit 231a that opens due to the pressure applied when inserting the protective tube 2.

[0045] The shape of the cut 231a is not particularly limited. In this embodiment, an H-shaped cut 231a is exemplified. Therefore, the movable part 231 is formed in a shape that includes the H-shaped cut 231a.

[0046] The usage of the medical device support 1C will be described below. Here, only the differences from the usage of the first embodiment will be described.

[0047] First, prepare the medical device support 1C. Specifically, prepare a base 10C having multiple claw portions 23. Next, pass one end of the protective tube 2 through the slit 231a of the movable portion 231 of the outermost claw portion 23. Then, sequentially pass the protective tube 2 through the slits 231a of the movable portion 231 of each of the remaining claw portions 23, and position the protective tube 2 in the predetermined location on the medical device support 1C. When the protective tube 2 is passed through the slit 231a, the protective tube 2 pushes the slit 231a open, forming a hole (illustrated by dashed lines). By passing the protective tube 2 through this hole, a reaction force (elastic force) from the movable portion 231 is applied to the outer surface of the protective tube 2. This reaction force fixes the protective tube 2 to the claw portion 23.

[0048] As described above, the medical device support 1C has the above configuration, and the protective tube 2 can be fixed to the medical device support 1C by the movable part 231 around the hole formed by the opening of the slit 231a. As a result, it is possible to prevent the protective tube 2 that houses the medical device 3 from shifting relative to the medical device support 1C or falling off the medical device support 1C.

[0049] In the embodiment described above, a medical device support 1C in which the movable part 231 has a slit 231a was described. The shape of the slit is not particularly limited. For example, a "+" shaped slit 231b (see Figure 6), an "l" shaped slit 231c (see Figure 7), or a "T" shaped slit 231d (see Figure 8) can also be used. With such a configuration, the protective tube can be fixed to the claw portion by passing the protective tube through the hole in the slit.

[0050] <Medical device set> [Fourth Embodiment] Figure 9 is a schematic diagram showing a fourth embodiment. As shown in Figure 9, the medical device set 100 comprises a medical device support 1A, a protective tube 2, and a medical device 3. In this embodiment, the medical device support 1A is exemplified as the medical device support. Since the medical device support 1A is the same as in the first embodiment, the same reference numerals are used for the same parts and their detailed description is omitted.

[0051] As shown in Figure 2, the medical device support 1A 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. The claw portion 21 has a hole 21h through which the protective tube 2 is inserted, and a movable portion 211 that is positioned to surround the hole 21h and is elastically deformable so that the hole 21h expands radially outward due to the pressure applied when the protective tube 2 is inserted.

[0052] The protective tube 2 is a component fixed to the medical device support 1A. 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 having an annular cross-section is exemplified.

[0053] 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.

[0054] 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.

[0055] 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 1A. A detailed explanation of this procedure is omitted here.

[0056] The medical device support 1A, to which the guide wire 3 is fixed, may be packaged in a bag (not shown). For example, a rectangular bag with three sides heat-sealed except for the opening may be used, and after inserting the medical device support 1A into the bag, the opening may be heat-sealed to seal the bag.

[0057] As described above, the medical device set 100 has the above configuration, so the protective tube 2 included in the medical device set 100 can be fixed to the medical device support 1A. As a result, it is possible to prevent the protective tube 2 from shifting relative to the medical device support 1A or from falling off the medical device support 1A.

[0058] 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.

[0059] In the embodiments described above, a cylindrical protective tube was exemplified as the protective tube 2 to be fixed. The protective tube is not particularly limited as long as it can be fixed to the medical device support. The protective tube may have a cross-sectional shape other than circular, such as an elliptical or polygonal shape. In such cases, the shape of the holes or cuts can be determined to match the cross-sectional shape of the protective tube.

[0060] 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.

[0061] In the embodiments described above, a configuration was described in which a protective tube 2 housing the medical device 3 is fixed to medical device supports 1A, 1B, and 1C. The medical device supports may directly fix the medical device without using a protective tube. In such a configuration of the medical device supports, the term "protective tube" in this specification described above can be replaced with "long medical device." Specific examples of applicable long medical devices include, for example, well-known long medical instruments such as guidewires, catheters, dilators, and Y-connectors.

[0062] In a medical device support for fixing a long medical device, the long medical device can be fixed to the medical device support by at least one of a movable part around an expanded hole and a movable part around a hole formed by an opening.
