Description

Catheter holder

Technical Field

The present invention relates to a catheter holder.

Background

A strip-shaped medical device such as a catheter is stored in a predetermined container in order to facilitate handling and protect the device at the preparation stage during transportation or before use. Further, for example, a catheter is stored or transported in a predetermined manner (in a wound state) by a holding tube as described in patent document 1 below or a catheter holder attachable to the holding tube.

Disclosure of Invention

As the catheter, there is a catheter having: a flexible tubular portion (such as a shaft or sheath) having an elongated shape; and a portion (held portion) having relatively high hardness such as a connector or a stem. As an example of such a catheter, there is a catheter for image diagnosis such as an IVUS catheter.

When treating or dilating a lesion such as a stricture, an operator such as a doctor observes the lesion using the catheter for image diagnosis. After observing the lesion, the operator temporarily pulls out the image diagnosis catheter from the biological lumen, and performs a process of dilating the lesion using the balloon catheter. The operator reinserts the image diagnosis catheter into the living body lumen in order to confirm the state of the lesion after expanding the lesion. In addition, depending on the state of the lesion after expansion, the operator may perform the following process (final expansion): after the catheter for image diagnosis is pulled out from the body lumen, the stricture portion is again dilated by the balloon catheter.

During the procedure, the diagnostic imaging catheter is connected to an external drive device such as an MDU. The catheter for image diagnosis is temporarily stored by using a holding tube used when a product is transported during a period in which use thereof is interrupted (for example, during a period in which a treatment by a balloon catheter or the like is performed). In this case, if the catheter holder is disposed between the holding tube and the external drive device, the catheter holder may get in the way when the catheter for image diagnosis is inserted into or removed from the holding tube or when the catheter for image diagnosis is inserted into the biological lumen again, and a smooth operation using the catheter for image diagnosis may be hindered.

The present invention has been made in view of the above problems, and an object thereof is to provide a catheter holder capable of preventing smooth progress of a surgery using a catheter from being hindered.

A catheter holder according to an aspect of the present invention for holding a catheter having a tubular portion and a held portion that is harder than the tubular portion includes: a mounting portion mounted to a bracket member capable of housing the tubular portion; a holding portion that holds the held portion; and a variable portion capable of changing a position of the holding portion with respect to the mounting portion.

The catheter holder has a variable portion capable of changing a position of the catheter holder on the holding portion side. The variable portion can retract the holding portion of the catheter holder to a predetermined position in a state where the tubular portion of the catheter is accommodated in the bracket member, such as during suspension of use of the catheter. Therefore, when an operator such as a doctor inserts and removes the catheter into and from the holder member or reinserts the catheter into the body lumen, the operator can prevent the operation from being hindered by the holding portion of the catheter holder, and the operation can be smoothly advanced.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. The following description is not intended to limit the technical scope and meaning of the terms described in the claims. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation and are different from actual ratios.

Fig. 1 is a plan view schematically showing a catheter holder 10 according to an embodiment, fig. 2 is a view showing a catheter holding member 100 included in the catheter holder 10, and fig. 3 is a view showing an attachment holding member 200 included in the catheter holder 10.

As shown in fig. 1, the catheter holder 10 of the present embodiment is configured as an instrument for holding a catheter 500 for image diagnosis, and the catheter 500 for image diagnosis is used for acquiring an image of a body lumen such as a blood vessel. Examples of the catheter to be held by the catheter holder 10 include an IVUS catheter, an OCT catheter, a double-type catheter having functions of both the IVUS catheter and the OCT catheter, and an OFDI catheter and other catheters for image diagnosis. However, the object to be held by the catheter holder 10 is not limited to the catheter for image diagnosis, and can be applied to other catheters (for example, an atherectomy catheter).

Referring to fig. 1, a catheter holder 10 has: a catheter holding member 100 for holding a catheter 500; and an attachment holding member 200 that holds

various attachments

610, 620, 630 attached to the duct 500.

In the present embodiment, the catheter assembly 1 is configured by the catheter holder 10, the catheter 500 held by the catheter holder 10, the holder member (holding tube) 300 that houses the tubular portion 510 of the catheter 500, and the packaging storage bag 400 that stores these members and devices.

A catheter 500 is illustrated.

As shown in fig. 1, the catheter 500 includes a tubular portion 510 housed in the bracket member 300, and held

portions

520 and 530 disposed on the proximal end side of the tubular portion 510 (the proximal side when the living body lumen is inserted).

For example, when the catheter 500 is an IVUS catheter or a double-type catheter, the tubular portion 510 is an elongated and flexible outer sheath or shaft portion (outer tubular shaft, inner tubular shaft, etc.). The held portion 520 is, for example, a unit connector that is harder than the tubular portion 510. The held portion 530 is, for example, a base end seat that is harder than the tubular portion 510.

The bracket member 300 is explained.

As shown in fig. 1, the bracket member 300 includes: a flexible tubular portion 310 that can be wound in a substantially circular shape; and a port portion 320 disposed at one end portion of the tubular portion 310.

The tubular portion 310 of the bracket member 300 can be, for example, a holding tube known in the medical field. Examples of the material of the tubular portion 310 include resin materials such as polyethylene and polypropylene.

The port 320 of the holder member 300 is used to supply the cleaning liquid to the inside of the holder member 300. The duct 500 is inserted into the port 320 from the distal end side of the duct 500 and can be inserted into the bracket member 300.

The shape, the number of windings, and the like of the tubular portion 310 of the bracket member 300 when wound are not particularly limited and can be appropriately changed.

The receiving bag 400 is explained.

The storage bag 400 can be formed of, for example, a plastic bag that is generally used for packaging medical instruments and the like. The receiving bag 400 has a base material 401 constituting a base material of the receiving bag 400, and a film portion 403 attached thereto.

The storage bag 400 has an opening 405 formed on the lower side (lower side in fig. 1) of the film portion 403, and a sealing portion 407 for sealing the opening 405. The base material 401 may be formed of, for example, a gas-permeable nonwoven fabric or the like that can be sterilized by Ethylene Oxide Gas (EOG) in a state where the conduit 500 is housed in the housing bag 400. The film portion 403 of the receiving bag 400 can be formed to be transparent or translucent, for example, in order to ensure the visual confirmation of the inside. The specific shape and structure of the storage bag 400, and the arrangement, posture, orientation, and the like of the catheter 500 in the state of being stored in the storage bag 400 are not particularly limited.

Next, the catheter retaining member 100 included in the catheter holder 10 will be described.

As shown in fig. 1, fig. 2 (a), and fig. 2 (B), the catheter holding member 100 includes: a mounting portion 110 mounted to the tubular portion 310 of the bracket member 300; a holding portion 120 that holds held

portions

520 and 530 of the catheter 500; and a variable portion 130 capable of changing the position of the holding portion 120 side with respect to the mounting portion 110.

As shown in fig. 1 and fig. 2 (a), the mounting portion 110 of the catheter holding member 100 includes: a 1 st support part 111 having

grooves

111a and 111b into which the tubular part 310 of the bracket member 300 can be fitted; a 2 nd support part 112 having

groove parts

112a and 112b into which the tubular part 310 of the bracket member 300 can be fitted; a 3 rd support part 113 having

grooves

113a and 113b into which the tubular part 310 of the bracket member 300 can be fitted; and a base portion 115 integrally connecting the

support portions

111, 112, 113.

The

support portions

111, 112, and 113 are disposed at different positions in the winding direction (R direction shown in fig. 1) of the tubular portion 310 of the bracket member 300. As shown in fig. 1, the

support portions

111, 112, and 113 are attached to the tubular portion 310 of the wound bracket member 300, thereby maintaining the tubular portion 310 in a wound state.

The shape, size, position, number, and the like of the groove portions formed in the

support portions

111, 112, and 113 are not particularly limited as long as the

support portions

111, 112, and 113 can be detachably attached to the bracket member 300. The number of the support portions is not limited to three, and can be increased or decreased as appropriate, and the position of the support portion can be changed as appropriate.

As shown in fig. 1 and fig. 2 (a), the holding portion 120 of the catheter holding member 100 includes: a 1 st holding part 121 in which a groove part 121a capable of holding a held part (base end seat) 530 of the catheter 500 is formed; a 2 nd holding portion 122 formed with a groove portion 122a capable of holding a held portion (unit connector) 520 of the catheter 500; an extension portion 124 integrally connecting the 1 st and 2

nd holding portions

121 and 122; and a base 125 connecting the extension 124 with the mounting portion 110.

Groove 121a of holding part 1 121 has a snap mechanism for detachably fixing held part 530 of catheter 500. Similarly, the groove 122a of the 2 nd holding portion 122 has a snap mechanism for detachably fixing the held portion 520 of the catheter 500.

The central axis C1 of the groove 121a of the 1 st holding portion 121 and the central axis C2 of the groove 122a of the 2 nd holding portion 122 are coaxially arranged. Therefore, as shown in fig. 1, when the catheter 500 is held by the catheter holding member 100, the held portion 530 of the catheter 500 and the held portion 520 of the catheter 500 are arranged substantially linearly along the axis of each of the

groove portions

121a and 122 a. Further, a part of the tubular portion 510 of the catheter 500 extending from the held portion 520 of the catheter 500 toward the distal end side (distal end side when inserting the living body lumen) is arranged substantially linearly toward the port portion 320 side of the bracket member 300.

The mounting portion 110 and the holding portion 120 constituting the catheter holding member 100 may be formed of, for example, a hard resin material such as ABS resin, polyethylene terephthalate, polymethyl methacrylate, or polycarbonate, glass, or ceramic.

As shown in fig. 2 (a) and 2 (B), the variable portion 130 includes a coupling portion 140 that detachably couples the holding portion 120 to the mounting portion 110.

The coupling portion 140 has: a protrusion 141 formed at an end of the base 115 of the mounting portion 110 (an end located on the holding portion 120 side); and a groove portion 142 formed at an end portion (end portion on the side of the mounting portion 110) of the base portion 125 of the holding portion 120.

As shown in fig. 2 (a), the protrusion 141 of the coupling portion 140 is configured to be fittable with the groove 142 of the coupling portion 140. The base portion 115 of the mounting portion 110 and the base portion 125 of the holding portion 120 are coupled by fitting the protrusion 141 and the groove 142. As shown in fig. 2B, the protrusion 141 of the coupling portion 140 can be separated from (can be released from) the groove 142 of the coupling portion 140. The base portion 115 of the mounting portion 110 and the base portion 125 of the holding portion 120 are disconnected from each other by the protrusion 141 being separated from the groove 142. The attachment portion 110 and the holding portion 120 can be repeatedly coupled and separated by the protrusion 141 and the groove 142.

The structure and form of the coupling portion 140 are not particularly limited as long as the attachment portion 110 and the holding portion 120 can be separated from each other. For example, the positions and the number of the protrusions 141 and the grooves 142 can be changed. For example, a structure in which the groove portion 142 is formed on the mounting portion 110 side and the protrusion portion 141 is formed on the holding portion 120 side, a thin portion (cut portion), bonding of different materials, bonding with an adhesive, or the like may be employed, and a structure in which re-connection is not possible when separated may be employed.

The coupling portion 140 of the catheter holder 10 has the following advantages.

For example, after an operator such as a doctor temporarily pulls out the catheter 500 from a living body lumen in an operation using the catheter (catheter for image diagnosis) 500, the operator may temporarily store the tubular portion 510 of the catheter 500 in the holder member 300. When the affected part is observed again after the treatment (for example, final expansion) of the affected part or the like is completed, the catheter 500 is also used, and thus the proximal end portion side (proximal end base 530 side) is also maintained in a state of being coupled to an external driving device such as an MDU while the tubular part 510 is temporarily stored using the bracket member 300. In order to maintain the tubular portion 510 of the catheter 500 in the wound state during the progress of the operation as described above, the bracket member 300 in the wound state into which the tubular portion 510 is inserted is attached to the

support portions

111, 112, and 113 of the catheter holder 10. When the holding portion 120 of the catheter holding member 100 is disposed between the holder member 300 and the external drive device during the operation, the holding portion 120 may get in the way when the tubular portion 510 is inserted into and removed from the holder member 300 or when the catheter 500 is inserted into the body lumen again, and the smooth progress of the operation may be hindered.

In order to solve the above problem, the operator releases the connection between the holding portion 120 and the mounting portion 110 as shown in fig. 2 (B), and retracts the holding portion 120 to a predetermined position, thereby preventing the smooth progress of the operation by the holding portion 120 from being hindered.

Next, the accessory holding member 200 included in the catheter holder 10 will be described.

As shown in fig. 1 and 3, the accessory holding member 200 includes: a plurality of

support portions

211, 212, 213, and 214 detachably attached to the bracket member 300; a 1 st holding part 221 capable of holding the 1 st attachment 610; a 2 nd holding portion 222 capable of holding the 2 nd attachment 620; a 3 rd holding part 223 capable of holding the 3 rd attachment 630; and a plurality of connecting

portions

225a, 225b, 225c, 225d, 225e extending between the

respective support portions

211, 212, 213, 214 and the respective holding

portions

221, 222, 223.

As shown in fig. 1 and 3, the 1 st support part 211 includes

groove parts

211a, 211b, and 211c into which the tubular part 310 of the bracket member 300 can be fitted. Similarly, the 2 nd support part 212 has

groove parts

212a, 212b, and 212c into which the tubular part 310 of the bracket member 300 can be fitted. Similarly, the 3 rd support part 213 has

grooves

213a, 213b, and 213c into which the tubular part 310 of the bracket member 300 can be fitted. Similarly, the 4 th support part 214 has

groove parts

214a, 214b, and 214c into which the tubular part 310 of the bracket member 300 can be fitted.

The

support portions

211, 212, 213, and 214 are disposed at different positions in the winding direction (R direction shown in fig. 1) of the tubular portion 310 of the bracket member 300. Of the

support portions

211, 212, 213, and 214, the 1 st support portion 211, the 2 nd support portion 212, and the 3 rd support portion 213 are disposed at positions close to each other, and the 4 th support portion 214 is disposed at a position distant from the other support portions. As shown in fig. 1, the

support portions

211, 212, 213, and 214 are attached to the tubular portion 310 of the wound bracket member 300, thereby maintaining the tubular portion 310 in the wound state.

support portions

211, 212, 213, and 214 are not particularly limited as long as the

support portions

211, 212, 213, and 214 can be detachably attached to the bracket member 300. The number of the support portions is not limited to four, and can be increased or decreased as appropriate, and the position of the support portion can be changed as appropriate.

As shown in fig. 1 and 3, a groove portion capable of holding the 1 st accessory 610 is formed in the 1 st holding portion 221 of the accessory holding member 200. The groove portion has a snap mechanism for detachably fixing the 1 st attachment 610.

The 1 st attachment 610 to be held by the 1 st holding part 221 is, for example, a syringe for supplying a prefilled liquid to the catheter 500.

As shown in fig. 1 and 3, the 2 nd holding portion 222 of the accessory holding member 200 includes the 1 st member 222a and the 2 nd member 222b for holding the 2 nd accessory 620. The 1 st member 222a and the 2 nd member 222b are separated from each other along the arrangement direction of the 2 nd attachments 620 (see fig. 1). In addition, the 1 st member 222a and the 2 nd member 222b are each formed with a groove portion capable of holding the 2 nd attachment 620. The groove portion has a snap mechanism for detachably fixing the 2 nd attachment 620.

The 2 nd attachment 620 to be held by the 2 nd holding part 222 is, for example, a liquid storage syringe used for replenishing the prefilled liquid when supplying the prefilled liquid to the catheter 500.

As shown in fig. 1 and 3, the 3 rd holding portion 223 of the accessory holding member 200 includes the 1 st member 223a, the 2 nd member 223b, and the 3 rd member 223c for holding the 3 rd accessory 630.

As shown in fig. 1 and 3, the 1 st member 223a has a groove portion for holding the connector portion 631 of the 3 rd attachment 630. In addition, a groove portion along which the pipe 632 of the 3 rd attachment 630 is provided is formed in the 2 nd member 223 b. In addition, a groove portion for holding a seat portion of the 3 rd attachment 630 is formed in the 3 rd member 223 c. The groove formed in the 1 st part 223a and the groove formed in the 3 rd part 223c have a snap mechanism for detachably fixing the 2 nd attachment 620.

The 3 rd attachment 630 to be held by the 3 rd holding portion 223 is, for example, a three-way stopcock used when supplying the prefilled liquid to the pipe 500.

As shown in fig. 3, the 1 st connecting portion 225a of the accessory holding member 200 connects the 1 st member 223a of the 3 rd holding portion 223 with the 1 st holding portion 221. The 2 nd connecting portion 225b connects the 1 st holding portion 221 and the 1 st member 222a of the 2 nd holding portion 222. In addition, the 3 rd connecting portion 225c connects the 1 st member 222a of the 2 nd holding portion 222 and the 2 nd member 222b of the 2 nd holding portion 222. Further, the 4 th connecting portion 225d connects the

respective support portions

211, 212, 213 to each other. The 5 th connection part 225e connects the 4 th connection part 225d, the 2 nd member 223b of the 3 rd holding part 223, the 4 th support part 214, and the 3 rd member 223c of the 3 rd holding part 223.

The specific shape, structure, and the like of the accessory holding member 200 (for example, the position of each holding portion, the position of each connecting portion, and the like) are not limited to those described in the drawings, and can be appropriately changed.

The accessory holding member 200 can be formed of a hard resin material such as ABS resin, polyethylene terephthalate, polymethyl methacrylate, or polycarbonate, glass, or ceramics. The accessory holding member 200 can be manufactured by, for example, integral molding by injection molding or the like.

As shown in fig. 1, the accessory holding member 200 holds the

accessories

610, 620, and 630 on the inner peripheral side (the center O side of the winding shown in fig. 1) of the bracket member 300 in a state of being attached to the tubular portion 310 of the bracket member 300 via the

support portions

211, 212, 213, and 214.

At the time of shipment of catheter assembly 1, for example, as shown in fig. 1, catheter holding member 100 and accessory holding member 200 are attached to bracket member 300. A manufacturing worker or the like can easily confirm whether or not each accessory 610, 620, 630 is held by the accessory holding member 200 in a plan view shown in fig. 1. This can effectively prevent the manufacturing worker or the like from leaving the factory or the like in a state where the

accessories

610, 620, and 630 are not fully installed.

The accessory holding member 200 can change the type and number of accessories to be held according to the type of the catheter 500. Thus, the accessory holding member 200 can be shared even when it is applied to different types of catheters. That is, the accessory holding member 200 can be applied to a larger number of types of catheters, and thus the product cost of the catheter can be reduced. In addition, for a catheter that does not require an accessory, the use of the accessory holding member 200 may also be omitted.

In addition, the accessory holding member 200 can hold and fix the

accessories

610, 620, and 630 by the groove portion having the snap mechanism. This allows an operator such as a doctor to easily and smoothly perform the operation when detaching the

accessories

610, 620, and 630 from the accessory holding member 200.

Preferably, the catheter holding member 100 has a structure (structure in which the holding

portions

121 and 122 are easily attached and detached) that allows easy release of the fixation to the catheter 500 by the 1 st holding portion 121 and the 2 nd holding portion 122. Similarly, it is preferable that the accessory holding member 200 has a structure (a structure in which the

support portions

211, 212, 213, and 214 are easily attached and detached) that allows the

support portions

211, 212, 213, and 214 to be easily released from the bracket member 300. As a structure that can easily release the fixation, for example, a structure that can easily come off by expanding a fixed portion (a groove portion or a peripheral portion thereof) when pressed by a finger or the like can be adopted. For example, the same structure as described above can be adopted as a structure that is easily attachable and detachable with respect to each modification described below.

The accessory holding member 200 has the following advantages when it is configured to be easily released from the fixed state. For example, when preparation for an operation using the catheter 500 is performed in an operating room, the preparation method differs depending on the number of persons performing the preparation work. When the number of persons performing the preparation work is large, the preparation work for pre-filling is performed at a work station different from the guide pipe stand. Therefore, each of the

accessories

610, 620, and 630 used for the pre-filling is preferably transported together with the pipe 500 to another work station. Since preparation for prefilling catheter 500 is performed at the catheter hub when there are few persons performing the preparation work, catheter 500 is directly prefilled with each of

accessories

610, 620, and 630 in a state of being taken out from storage bag 400. As described above, the procedure of the preparation operation of the catheter 500 differs depending on the number of workers in the operating room. Therefore, the operator who performs the operation preparation can make the preparation work progress more smoothly by appropriately attaching and detaching the attachment holding member 200 to and from the catheter holding member 100 according to the number of operators in the operating room, the progress of the preparation work, and the like.

Next, the operational effects of the catheter holder 10 of the present embodiment will be described.

The catheter holder 10 of the present embodiment includes: a mounting portion 110 mounted to a bracket member 300, the bracket member 300 being capable of housing a tubular portion 510 of a catheter 500; a holding portion 120 that holds held

portions

The catheter holder 10 having the above-described configuration has the variable portion 130 that can change the position of the catheter holder 10 on the holding portion 120 side. The variable portion 130 can retract the holding portion 120 of the catheter holder 10 to a predetermined position in a state where the tubular portion 510 of the catheter 500 is accommodated in the holder member 300, such as during suspension of use of the catheter 500. Therefore, when an operator such as a doctor inserts and removes the catheter 500 into and from the holder member 300 or reinserts the catheter 500 into a living body lumen, the operator can prevent the holding portion 120 of the catheter holder 500 from interfering with these operations, and the operation can be smoothly performed.

The variable portion 130 of the catheter holder 10 has a coupling portion 140 that detachably couples the holding portion 120 to the mounting portion 110. Therefore, an operator such as a doctor can retract the holding portion 120 to a desired position by a simple operation of separating the holding portion 120. Further, since the variable portion 130 is configured with a relatively simple structure, the manufacturing cost of the catheter holder 10 can be reduced.

The catheter holder 10 further includes an attachment holding member 200 configured to be attachable to and detachable from the bracket member 300. The accessory holding member 200 holds the

accessories

610, 620, and 630 attached to the duct 500 on the inner peripheral side (the center O side of the winding shown in fig. 1) of the bracket member 300 in the wound state.

According to the catheter holder 10 configured as described above, a manufacturing worker or the like can easily confirm whether or not the

accessories

610, 620, 630 are packaged at the time of product shipment or the like. Further, the

accessories

610, 620, and 630 are held in the remaining space on the inner peripheral side of the bracket member 300, so that the product can be compactly stored, and an increase in the occupied area of the product can be suppressed.

Next, modifications of the catheter holding member 100 included in the catheter holder 10 will be described. In the description of each modification, the description of the components and the like already described in the above embodiment is appropriately omitted.

Fig. 4 (a) and 4 (B) show a catheter holding member 100A according to modification 1.

The configuration of the variable portion 130 in the catheter holding member 100A of modification 1 is different from that of the above-described embodiment. Specifically, the variable portion 130 includes a bent portion 150 that can bend a part of the catheter holder 100A in a direction in which the holding portion 120 approaches the attachment portion 110 (a direction indicated by an arrow in fig. 4B).

The bent portion 150 may be formed of a member such as a hinge that connects the base portion 115 of the attachment portion 110 and the base portion 125 of the holding portion 120 so as to be bendable, for example. As shown in fig. 4 (B), when the holding portion 120 is retracted, the holding portion 120 is pulled up from the vicinity of the bent portion 150 as a base point. For example, by moving the holding portion 120 toward the inner peripheral side of the bracket member 300 (toward the center O of winding shown in fig. 1), the holding portion 120 can be prevented from interfering with the operation.

The specific structure of the bent portion 150 is not particularly limited. For example, a part of the holding portion 120 may be formed of a material or thickness that can be bent, and the bent portion 150 may be formed of such a part.

Fig. 5 (a) and 5 (B) show a catheter holding member 100B according to modification 2.

The configuration of the variable portion 130 in the catheter holding member 100B of modification 2 is different from that of the above-described embodiment. Specifically, the variable portion 130 includes a rotating portion 160 that can rotate a part of the catheter holding member 100B in a direction in which the holding portion 120 approaches the mounting portion 110 (a direction indicated by an arrow in fig. 5B).

The rotating portion 160 may be constituted by, for example, a shaft member and a bearing that relatively rotatably couple the base portion 115 of the mounting portion 110 and the base portion 125 of the holding portion 120. The bearing can be formed by, for example, a through hole formed in the base portion 115 of the mounting portion 110 and the base portion 125 of the holding portion 120, and the shaft member can be formed by, for example, a rotating shaft inserted into the through hole.

As shown in fig. 5B, when the holding portion 120 is retracted, the holding portion 120 is moved toward the inner peripheral side (the center O side of winding shown in fig. 1) of the bracket member 300 with the rotating portion 160 as a base point. In order to prevent the tubular portion 310 of the bracket member 300 from obstructing the rotation of the holding portion 120 when the holding portion 120 is rotated, for example, as shown in fig. 5 (B), only one support portion 111 may be attached to the tubular portion 310 of the bracket member 300.

The specific structure of the rotating portion 160 is not particularly limited. For example, the rotatable range (rotation angle) may be arbitrarily set as long as the holding portion 120 can be moved to a desired position. The holding member 100B may be provided with a lock mechanism (e.g., a mechanism for positioning the holding unit 120 by mechanical fitting or the like) for maintaining a state in which the rotating unit 160 is rotated and moved to a desired position.

Fig. 6 shows a catheter holding member 100C according to modification 3.

The catheter holding member 100C of modification 3 differs from the above-described embodiment in the orientation of the 1 st supporting portion 111 of the mounting portion 110 and the 2 nd supporting portion 112 of the mounting portion 110. Specifically, the

grooves

111a and 111b formed in the 1 st support portion 111 and the

grooves

112a and 112b formed in the 2 nd support portion 112 are disposed so as to face each other in the fitting direction with respect to the bracket member 300.

As shown in fig. 6, the

groove portions

111a and 111b of the 1 st support portion 111 are attached by inserting the tubular portion 310 of the bracket member 300 from above. On the other hand, the

grooves

112a and 112b of the 2 nd support portion 112 are attached by inserting the tubular portion 310 of the bracket member 300 from below. Thus, when the tube-shaped portion 310 of the bracket member 300 approaches the catheter holding member 100C from one side (e.g., the upper side or the lower side), it is not fitted into the

grooves

111a and 111b of the 1 st support portion 111, nor fitted into the

grooves

112a and 112b of the 2 nd support portion 112. The

grooves

113a and 113b of the 3 rd supporting portion 113 are formed so as to face in the same direction as the

grooves

111a and 111b of the 1 st supporting portion 111. Thus, the tubular portion 310 of the bracket member 300 is not fitted into the

grooves

113a and 113b of the 3 rd supporting portion 113.

As shown in fig. 6, the catheter holding member 100C of the present modification includes an extension portion 126 extending from the base portion 125 of the holding portion 120, and a 4 th support portion 114 formed at an end of the extension portion 126.

The 4 th support portion 114 is formed with a plurality of

grooves

114a and 114b that are detachable from the tubular portion 310 of the bracket member 300. For example, when the catheter holding member 100C is attached to the tubular portion 310 of the bracket member 300, the catheter holding member 100C can be fixed to the tubular portion 310 of the bracket member 300 only via the 4 th support portion 114. As described above, by fixing the bracket member 300 and the catheter holding member 100C via only one support portion 114, the catheter holding member 100C as a whole can be detached from the bracket member 300 with a simple operation of releasing the fixing of the 4 th support portion 114.

Next, modifications of the accessory holding member 200 included in the catheter holder 10 will be described. In the description of each modification, the description of the components and the like already described in the above embodiment is appropriately omitted.

Fig. 7 shows an accessory holding member 200A according to modification 1.

Accessory holding member 200A of modification 1 includes auxiliary holding member 230 configured to be attachable to and detachable from accessory holding member 200A and capable of holding accessories attached to duct 500.

The auxiliary holding member 230 can be attached to any position of the connecting

portions

225a, 225b, 225c, 225d, 225e of the accessory holding member 200A.

The auxiliary holding member 230 has: a support portion 231 having a groove portion 231a for attaching and detaching the accessory holding member 200A; and a main body 232 formed with a groove portion capable of holding an accessory. For example, when accessories other than the

accessories

610, 620, and 630 are held by the accessory holding member 200A, the auxiliary holding member 230 is attached to the accessory holding member 200A, whereby another accessory can be further held via the auxiliary holding member 230. The auxiliary holding member 230 increases the number of retainable accessories by utilizing the clearance (space between the connecting portions) of the accessory holding member 200A. Therefore, the product occupied by the accessory holding member 200A can be prevented from increasing in the use of the catheter 500 and the like.

The specific structure of the auxiliary holding member 230 is not particularly limited. For example, any accessory to be held by the auxiliary holding member 230 is optional. The structure, shape, mounting position, number, and the like of the auxiliary holding member 230 can be appropriately changed.

Fig. 8 shows an accessory holding member 200B according to modification 2.

The accessory holding member 200B of modification 2 includes fitting

type fixing portions

241 and 242 to which one end sides of the

accessories

610 and 620 can be fixed. The fixing

portions

241 and 242 are provided in the connecting portion 240. The fixing portion 241 is constituted by a luer fitting type fixing portion to be fitted to the distal end cylinder portion of the attachment (syringe for prefilling) 610. The fixing portion 242 is formed by a luer-type fixing portion that is fitted to the distal end cylindrical portion of the attachment (syringe for storing liquid) 620.

As in the accessory holding member 200B of the present modification, the structure for holding the

accessories

610 and 620 is not limited to the groove portion. In addition, one accessory holding member 200 may be provided with both a holding structure by the groove portion and a holding structure of a fitting type (for example, a luer type).

Fig. 9 shows an accessory holding member 200C according to modification 3.

The accessory holding member 200C of modification 3 includes: a base part 250 having a groove 251 formed therein for accommodating the

accessories

610, 620, and 630; and a cover member 260 that covers the

accessories

610, 620, and 630 housed in the groove portion 251 of the base portion 250.

The base portion 250 can be formed of, for example, a resin molded product in which the concave groove portion 251 is formed. The cover member 260 may be formed of a transparent or translucent resin film (film-like member), for example. The cover member 260 is rotatably attached to the base portion 250 as indicated by an arrow in fig. 9, for example. For example, a rod-shaped member (pin or the like) for rotatably mounting the cover member 260 to the base portion 250 can be used for mounting the cover member 260 to the base portion 250.

When the surgeon uses the

attachments

610, 620, and 630, the surgeon, such as a doctor, can remove the

attachments

610, 620, and 630 from the groove portions 251 of the base portion 250 by moving the cover member 260 relative to the base portion 250. Each

attachment

610, 620, 630 is not securely fixed relative to base portion 250 so that the operator can easily remove each

attachment

610, 620, 630.

The cover member 260 may be detachably fixed (e.g., bonded or welded) to the base member 250, for example.

Fig. 10 shows an accessory holding member 200D according to modification 4.

As in catheter holding member 100C (see fig. 6) of the modification example, accessory holding member 200D of modification example 4 is arranged such that the directions of

grooves

211a, 211b, and 211C formed in first support part 211 and the directions of

grooves

212a, 212b, and 212C formed in second support part 212 are opposite to each other. Further, the bracket member 300 can be fixed only via the 4 th support part 214. Thus, the accessory holding member 200D can be removed from the bracket member 300 as a whole by a simple operation of releasing the fixing of the 4 th supporting portion 214.

Fig. 11 shows an accessory holding member 200E according to modification 5.

The accessory holding member 200E of modification 5 has a plurality of finger-clasping

portions

261, 262, 263, and 264.

As shown in FIG. 11, the 1 st holding portion 221 holding the 1 st attachment 610 has a 1 st finger tab portion 261 capable of being grasped by a finger tab when the 1 st attachment 610 is detached. In the 1 st finger-catch portion 261,

convex portions

261a, 261b are formed which protrude toward the surface side (the surface side in the plan view shown in fig. 11).

In the plan view shown in fig. 11, the respective

convex portions

261a, 261b formed in the 1 st finger-clasping portion 261 have a substantially elliptical shape.

When the operator or the like detaches the 1 st attachment 610 from the 1 st holding part 221, the operator places fingers on the front surface side of the 1 st finger-fastening part 261 and pulls up the 1 st attachment 610 from the back surface side (the side opposite to the front surface side shown in fig. 11) of the 1 st finger-fastening part 261. At this time, the respective

convex portions

261a, 261b formed in the 1 st finger-clasping portion 261 prevent the finger from slipping. Therefore, the operator or the like can easily detach the 1 st attachment 610 from the 1 st holding portion 221.

As shown in fig. 11, the 2 nd holding portion 222 holding the 2 nd attachment 620 has the 2 nd finger-catch portion 262 capable of being grasped by the finger-catch. The 2 nd finger-hold part 262 is formed with a plurality of

projections

262a, 262b for preventing slipping of the fingers. When the operator or the like removes the 2 nd attachment 620 from the 2 nd holding portion 222, the operator can easily remove the 2 nd attachment 620 by placing a finger on the 2 nd finger-catch portion 262.

The 3 rd part 223c holding the 3 rd holding part 223 of the 3 rd attachment 630 has a 3 rd finger-catch portion 263 capable of being gripped by a finger catch. The 3 rd finger-clasping portion 263 has a plurality of protrusions 263a, 263b for preventing slipping of the fingers formed thereon. When the operator or the like removes the 3 rd attachment 630 from the 3 rd member 223c of the 3 rd holding portion 223, the operator can easily remove the 3 rd attachment 630 by placing fingers on the 3 rd finger-catch portion 263.

The 4 th support portion 214 attached to the tubular portion 310 of the bracket member 300 has a 4 th finger grip portion 264 that can be grasped by a finger grip. A plurality of

projections

264a, 264b for preventing slipping of the fingers are formed on the 4 th finger-fastening portion 264. When the operator or the like detaches the accessory holding member 200E from the tubular portion 310 of the bracket member 300, the operator can easily detach the accessory holding member 200E by placing a finger on the 4 th finger-catch portion 264.

The shapes, positions, dimensions, numbers, and the like of the respective finger-clasping

portions

261, 262, 263, and 264 and the shapes, positions, dimensions, numbers, and the like of the respective

convex portions

261a, 261b, 262a, 262b, 263a, 263b, 264a, and 264b are not limited to those shown in the drawings, and can be changed as appropriate. In order to prevent the finger from slipping, for example, the convex portion and the concave portion may be disposed in the finger-grip portion, or only the concave portion may be disposed. Further, a convex portion or a concave portion may be disposed on the back surface side of the finger-fastening portion.

As shown in fig. 11, the accessory holding member 200E has a plurality of

housing portions

271, 272, 273, 274, 275. Each of the

housing portions

271, 272, 273, 274, and 275 has a shape curved convexly toward the front surface side of the accessory holding member 200E.

The 1 st cover 271 prevents the 1 st accessory 610 from contacting the film portion 403 (see fig. 1) of the receiving bag 400 and damaging the film portion 403 by friction or the like.

The 2 nd shell portion 272 prevents the 2 nd accessory 610 from contacting the film portion 403 of the receiving bag 400 to cause breakage of the film portion 403 due to friction or the like.

The 3 rd housing part 273 prevents the connector part 631 of the 3 rd accessory 630 from contacting the film part 403 of the receiving bag 400 and causing the film part 403 to be damaged by friction or the like.

The 4 th and 5

th case parts

274 and 275 prevent the tube 632 of the 3 rd attachment 630 from contacting the film portion 403 of the storage bag 400 and damaging the film portion 403 by friction or the like.

The shapes, positions, sizes, numbers, and the like of the

housing portions

271, 272, 273, 274, and 275 are not limited to those shown in the drawings, and can be changed as appropriate.

Next, a catheter holding member 100D according to another embodiment of the present invention will be described with reference to fig. 12 to 14. Note that the same components as those described in the above embodiment and each modification are appropriately omitted from description.

Fig. 12 is an enlarged perspective view showing a part of the catheter holding member 100D, fig. 13 is an enlarged plan view showing a part of the catheter holding member 100D, and fig. 14 is a cross-sectional view of the catheter holding member 100D corresponding to the line of arrows 14-14 shown in fig. 13.

The configuration of the mounting portion 110D in the catheter holding member 100D of the present embodiment is different from the catheter holding member 100 (see fig. 2) of the above-described embodiment. The catheter holding member 100D of the present embodiment does not have a variable portion, but may have a variable portion. In fig. 12 to 14, the holding portion for holding the held portions 520 and 530 (see fig. 1) of the catheter 500 is not shown. The holding portion may have the same configuration as described in the above embodiment, or may have a different configuration.

The mounting portion 110D has: a 1 st support part 111 formed with

grooves

111a, 111b into which a part of the tubular part 310 of the wound bracket member 300 is fitted; and a 2 nd support portion 112 which is disposed at a position different from the 1 st support portion 111 in a winding direction of the tubular portion 310 of the bracket member 300 (a direction indicated by an arrow R shown in fig. 12 and 13), and which has a holding space 112c capable of holding a part of the tubular portion 310 of the bracket member 300 in a wound state.

The 2 nd support portion 112 is open to the center O side (the direction indicated by the arrow a in fig. 12) of the winding of the tubular portion 310 of the bracket member 300 shown in fig. 1 and the side in the winding direction of the tubular portion 310 of the bracket member 300.

As shown in fig. 12 and 13, the mounting portion 110D includes the 3 rd supporting portion 113 disposed on the opposite side of the 1 st supporting portion 111 in the winding direction of the tubular portion 310 of the bracket member 300 with respect to the 2 nd supporting portion 112. The 3 rd support part 113 is formed with

grooves

113a and 113b into which a part of the tubular part 310 of the bracket member 300 in a wound state is fitted.

As shown in fig. 12 and 14, the 2 nd support portion 112 includes a 1 st protruding portion 112a and a 2 nd protruding portion 112b that protrude toward the center O side of the winding of the tubular portion 310 of the bracket member 300.

The 1 st projecting portion 112a is disposed so as to cover a part of the tubular portion 310 of the bracket member 300 wound around the side (the upper side of the arrow a shown in fig. 12 and 14) where the

groove portions

111a and 111b of the 1 st supporting portion 111 are open. Further, in fig. 14, the wound portions of the tubular portion 310 of the bracket member 300 are denoted by

reference numerals

311, 312.

As shown in fig. 14, the 2 nd projection 112b is disposed to face the 1 st projection 112a so as to form a holding space 112c between the 1 st projections 111.

The 1 st projecting portion 112a extends substantially parallel to the base portion 115 toward the center O side of winding of the tubular portion 310 of the bracket member 300. By forming the 1 st projecting portion 112a in this manner, the 1 st projecting portion 112a can press the tubular portion 310 of the bracket member 300 from above in a state where the tubular portion 310 of the bracket member 300 is fitted in the

groove portions

111a, 111b, 113a, and 113b of the

support portions

111 and 113, and the tubular portion 310 of the bracket member 300 can be firmly fixed to the

groove portions

111a, 111b, 113a, and 113 b.

The inclination angle θ 1 of the 1 st projection 112a with respect to the base 115 can be set to, for example, 1 ° or less.

Preferably, the height position (the position in the vertical direction in fig. 14) of the 1 st protruding portion 112a is set such that the

wound portions

311 and 312 of the bracket member 300 are brought into contact with the inner surface of the 1 st protruding portion 112a on the upper side thereof in a state where the tubular portion 310 of the bracket member 300 is fitted in the

groove portions

111a, 111b, 113a, and 113b of the

support portions

111 and 113. Preferably, the height position of the 1 st projecting portion 112a is set so that a gap g is formed between the 2 nd projecting portions 112b in each of the

wound portions

311 and 312 of the bracket member 310.

By setting the height of the 1 st projecting portion 112a to a position where the gap g is formed as described above, when the attachment portion 110D is detached from the tubular portion 310 of the bracket member 300 as described later (see fig. 14), the attachment portion 110D can be rotated relative to the

respective portions

311, 312 of the tubular portion 310 of the bracket member 300. The size and the position of the gap g are not particularly limited as long as the mounting portion 110D can be rotated. Therefore, the gap g may be formed at least between the 2 nd projecting portion 112b and a part 311 of the tubular portion 310 of the bracket member 300.

The 2 nd projecting portion 112b projects more toward the center O side of the winding of the tubular portion 310 of the bracket member 300 than the 1 st projecting portion 112 a. By forming the 2 nd projecting portion 112b in this manner, the work of inserting the tubular portion 310 of the bracket member 300 into the holding space 112c can be easily performed. In addition, in the tubular portion 310 of the bracket member 300, the

portions

311 and 312 held by the holding space 112c of the 2 nd support portion 112 can move toward the upper side of the mounting portion 110D while being guided by the upper inner surface of the 1 st protruding portion 112 a. Therefore, the

parts

311 and 312 of the tubular portion 310 of the bracket member 300 held in the holding space 112c of the 2 nd support part 112 can be easily moved from the holding space 112c to the outside of the holding space 112 c.

The 2 nd projecting portion 112b is inclined and extends away from the 1 st projecting portion 112a toward the center O side of winding of the tubular portion 310 of the bracket member 300. By forming the 2 nd projecting portion 112b in this way, the gap g can be easily formed between the 2 nd projecting portions 112b in the

wound portions

311 and 312 of the bracket member 310. The inclination angle θ 2 of the 2 nd projecting portion 112b with respect to the base portion 115 is preferably larger than 0 ° and 30 ° or less, and more preferably 5 ° or more and 15 ° or less, for example.

When the operator or the like detaches the tubular portion 310 of the bracket member 300 from the attachment portion 110D, as shown in fig. 14, the operator or the like detaches the tubular portion 310 of the bracket member 300 from the

support portions

111 and 113 by rotating the distal end side of the attachment portion 110D (the side of the center O of winding of the tubular portion 310 of the bracket member 300) with an arbitrary portion of the base portion 115 as a fulcrum s 1. The 2 nd support portion 112 pivots upward of the bracket member 110D as indicated by arrows in fig. 14, for example.

When the operator or the like performs the above-described operation, the tubular portion 310 of the bracket member 300 moves in a direction (in the direction of arrow a in fig. 12 and 13, and upward in fig. 14) in which the portions that engage with the

grooves

111a, 111b, 113a, and 113b of the

support portions

111 and 113 are pulled out from the

grooves

111a, 111b, 113a, and 113 b. On the other hand, the

portions

311 and 312 of the tubular portion 310 of the bracket member 300, which are held by the holding space 112c of the 2 nd support portion 112, move from the holding space 112c to the outside of the holding space 112c while being guided by the inner surface of the upper portion of the 1 st protruding portion 112a, and move toward the upper side of the mounting portion 110D in the same manner as the tubular portion 310 of the bracket member 300 fitted to the

groove portions

111a, 111b, 113a, and 113 b. Therefore, the operator or the like can easily detach the tubular portion 310 of the bracket member 300 from the

groove portions

111a, 111b, 113a, and 113b of the

support portions

111 and 113 by rotating the distal end side of the mounting portion 110D (the center O side of the winding of the tubular portion 310 of the bracket member 300).

When the operator or the like temporarily takes out the tubular portion 510 of the catheter 500 from the tubular portion 310 of the bracket member 300 and then inserts the tubular portion 510 of the catheter 500 into the tubular portion 310 of the bracket member 300 again, the catheter holder becomes a hindrance to the operation, the operator or the like removes the mounting portion 110D from the tubular portion 310 of the bracket member 300 in accordance with the above-described operation procedure. The operator or the like can easily detach the attachment portion 110D from the tubular portion 310 of the bracket member 300, and thus can smoothly perform the operation of reinserting the tubular portion 510 of the catheter 500 into the tubular portion 310 of the bracket member 300.

The catheter holder according to the present invention has been described above with reference to the embodiments, but the present invention is not limited to the configuration described in the embodiments, and can be appropriately modified according to the description of the technical means.

For example, in the description of the embodiment, the configuration in which the catheter holder has the catheter holding member and the accessory holding member has been described, but the catheter holder may be configured only by the catheter holding member.

The catheter to be held by the catheter holder is not particularly limited as long as it has a tubular portion and a held portion (e.g., a predetermined connector). The number, kind, and the like of the accessories held by the accessory holding member are not limited to those described in the embodiments.

Further, for example, the catheter holding member described in the embodiment, the catheter holding member described in each modification, and the like can be configured by appropriately combining the structurally different portions. Similarly, the accessory holding member described in the embodiment and the accessory holding members described in the respective modifications can be configured as one accessory holding member by appropriately combining the structurally different portions. In addition, each catheter holding member and each attachment holding member described in the specification can be arbitrarily combined.

The present application is based on japanese patent application No. 2017-140336 filed on 19.7.2017, the disclosure of which is incorporated by reference in its entirety.
