Description

  The present invention relates to a holder.

  In recent years, the peritoneal dialysis treatment method is smaller and simpler, the treatment costs are lower, the peritoneal adhesion can be prevented, and the burden on the patient is less than the dialysis method using an artificial kidney. It is attracting attention for such reasons.

  Among these peritoneal dialysis methods, especially continuous ambulatory peritoneal dialysis, the patient can change dialysate containers (bags) at home or at work, and thus return to society. It is easy and attracts much attention.

  In this continuous portable peritoneal dialysis method, a tube connected to the patient side and a tube connected to the dialysate bag side containing the dialysate are connected. These tubes are connected to each other by connecting connectors installed at the ends of the tubes (see, for example, Patent Document 1). Patent Document 1 discloses that a cap is temporarily attached to a connector of a tube connected to a patient until the connectors are connected to each other.

  Some caps are stored aseptically in a packaging bag in the following state, for example. The cap is fixed to the pedestal by fitting, and the pedestal is stored in the packaging bag together with the pedestal. When using the cap, the packaging bag is first opened, and then the cap is taken out together with the pedestal and placed on a table, for example. Then, for example, with the left hand holding the pedestal against the table, the cap is pulled out of the pedestal with the right hand. Thus, the operation | work which pulls out a cap using both hands is a burden for a patient, and it will take time until it connects between connectors. Further, depending on the force at the time of pulling out, the cap may be in a posture such that falling bacteria adhere to the inside. Such adhesion of falling bacteria is not preferable in peritoneal dialysis.

FIG. 1 is a schematic view showing a peritoneal dialysis set. FIG. 2 is a perspective view showing a state in which the holder of the present invention holds the cap. 3 is a view as seen from the direction of arrow A in FIG. 4 is a cross-sectional view taken along line BB in FIG. FIG. 5 is a cross-sectional view taken along line CC in FIG. 6 is a vertical cross-sectional view showing a state in which the lid body is detached from the state shown in FIG. FIGS. 7 to 9 are perspective views sequentially showing processes until the cap held by the holder of the present invention is attached to the connector. In the following, for convenience of explanation, the upper side in FIGS. 2 and 4 to 9 is referred to as “up (upward)” or “front side”, and the lower side is referred to as “lower (downward)” or “back side”.

  The peritoneal dialysis set 100 shown in FIG. 1 is suitable for continuous ambulatory peritoneal dialysis among the peritoneal dialysis methods, that is, when performing peritoneal dialysis. The dialysate is injected (supplied) into the inside (intraperitoneal), and then the dialysate drainage is collected.

  The peritoneal dialysis set 100 includes a dialysate bag 14 pre-filled with dialysate, a drain bag 19 for collecting dialysate drain, and bag-side tubes connected to the dialysate bag 14 and drain bag 19, respectively. 11, a transfer tube 18 connected to a catheter (not shown) placed in the patient's peritoneum, and a peritoneal dialysis connector 12 that removably connects the bag side tube 11 and the transfer tube 18. ing. In the peritoneal dialysis set 100, the dialysate bag 14 or the drainage bag 19 may be omitted as necessary.

  In the peritoneal dialysis set 100, the bag side tube 11, the transfer tube 18, and the peritoneal dialysis connector 12 constitute a dialysis line 10 through which dialysate (including its drainage) passes. The peritoneal dialysis connector 12 includes a first connector 121 and a second connector 122. Then, by connecting the first connector 121 and the second connector 122, the dialysate can flow down from the upstream toward the downstream in the dialysis line 10. Moreover, the middle of the dialysis line 10 can be separated by releasing the connection between the first connector 121 and the second connector 122. As a result, for example, the used dialysate bag 14 and drainage bag 19 can be replaced with new, ie, unused dialysate bag 14 and drainage bag 19.

  The bag-side tube 11 includes a tube 111 that connects the dialysate bag 14 and the first connector 121 of the peritoneal dialysis connector 12, and a branch tube 112 branched from the middle of the tube 111. The tube 111 and the branch tube 112 communicate with each other via the branch portion 113. The branch tube 112 is connected to the drainage bag 19 on the side opposite to the branch portion 113. Such a bag-side tube 11 can be selectively closed to switch the dialysate flow path. In other words, the bag-side tube 11 closes the vicinity of the branch portion 113 of the branch tube 112 when dialysate is supplied from the dialysate bag 14 to the patient side. Further, when the drainage is collected from the patient side into the drainage bag 19, the vicinity of the dialysis fluid bag 14 side of the branch portion 113 of the tube 111 is closed. The method for closing the tube is not particularly limited, and examples thereof include a method of attaching a clamp to a tube to be closed.

  A second connector 122 of the peritoneal dialysis connector 12 is connected to the opposite side of the transfer tube 18 from the patient side. In addition, the transfer tube 18 is provided with a connector 17 that is detachably connected in the middle of the transfer tube 18 and a roller clamp 16 that opens and closes the transfer tube 18 on the second connector 122 side of the connector 17.

  By the way, in the connection release state in which the connection between the first connector 121 and the second connector 122 is released, the cap 9 is temporarily attached to the second connector 122. This is to prevent, for example, falling bacteria from adhering to the second connector 122 during the disconnected state.

  As shown in FIG. 2, the cap 9 is packaged in a bag-like packaging material 30 made of, for example, aluminum in an unused state, thereby forming a cap package 20. The cap 9 is held by the holder 1 in the packaging material 30. As described above, the cap package 20 includes the cap 9, the holder 1 that holds the cap 9, and the packaging material 30 that wraps the cap 9 held by the holder 1 together with the holder 1. ing. When the cap 9 is used by being attached to the second connector 122, the cap 9 is removed from the packaging material 30 together with the holder 1, and then the lid 3 is detached from the holder body 2 before use.

Hereinafter, the cap 9 and the holder 1 will be described.
First, the cap 9 will be described.

  As shown in FIG. 4, the cap 9 is a cylinder having an opening 94 whose lower side (one end side) is open and an upper side wall portion 93 which is a closed portion whose upper side (the other end side) is closed. It is a shape. Specifically, the cap 9 is a cylindrical outer cylinder portion 91, and is disposed concentrically on the inner side of the outer cylinder portion 91, and has a cylindrical inner cylinder portion 92, and the outer cylinder portion 91 and the inner cylinder portion 92. And an upper side wall portion 93 that connects the two. In addition, the side opposite to the upper side wall portion 93 is an opening portion 94 that opens downward.

  The outer cylinder portion 91 has a female screw 912 formed on the inner peripheral portion 911 thereof. Accordingly, the cap 9 can be connected to the male screw 123 of the second connector 122 by screwing (see FIGS. 7 to 9). Further, an enlarged diameter portion 914 having an increased outer diameter is formed at the lower portion of the outer peripheral portion 913 of the outer cylinder portion 91. The enlarged diameter portion 914 is a portion having the largest outer diameter in the cap 9, that is, a portion having a maximum outer diameter. A plurality of ribs 915 are formed to protrude from a portion of the outer peripheral portion 913 above the enlarged diameter portion 914 (see, for example, FIG. 2). Each rib 915 extends along the central axis direction of the outer tube portion 91, that is, along the vertical direction, and is arranged at equal intervals along the circumferential direction of the outer tube portion 91. By forming such a rib 915, when the cap 9 is screwed to the second connector 122, it is possible to easily rotate at least one rib 915 with a fingertip. The meeting can be performed quickly.

  The inner cylinder part 92 is shorter than the outer cylinder part 91 and is located on the upper side wall part 93 side. The inner peripheral portion 921 of the inner cylindrical portion 92 has an inner diameter that changes in accordance with the shape of the second connector 122.

  A ring-shaped packing 96 is supported and fixed on the inner cylinder portion 92. In a state where the cap 9 is connected to the second connector 122, the liquid tightness between them is maintained by the packing 96, and thus liquid leakage can be prevented.

  A sponge 95 impregnated with a disinfectant such as povidone iodine is inserted between the outer tube portion 91 and the inner tube portion 92 up to the upper side wall portion 93. The second connector 122 connected from the opening 94 of the cap 9 comes into contact with the sponge 95 and is sterilized.

  The cap 9 having such a configuration is accommodated in the packaging material 30 in a sterilized state. In addition, although it does not specifically limit as a sterilization method, For example, it is preferable to use the method by autoclave sterilization.

Next, the holder 1 will be described.

The holder main body 2 is a member that supports the cap 9, and the lid 3 is a member that covers the opening 94 of the cap 9 in a state of being attached to the holder main body 2 (hereinafter referred to as “attached state”). . In addition, it does not specifically limit as a constituent material of the holder main body 2 and the cover body 3, For example, it is preferable to use various resin materials, such as cyclic polyolefin and polyester, at the point that mold shaping | molding is easy. . In view of manufacturing cost, elasticity, and the like, various resin materials such as polypropylene, polycarbonate, polyacetal, and the like can also be used.

  As shown in FIGS. 2-6, the holder main body 2 has the plate-shaped body 21 in which the whole shape makes plate shape. The plate-like body 21 has a thickness smaller than the height of the cap 9. The plate-like body 21 is provided with a support portion 22 that supports the cap 9 and a finger hook portion 23 that hangs a finger of a user who uses the cap 9, for example.

  The support part 22 is provided at the center of the plate-like body 21. As shown in FIG. 4, the support part 22 is comprised by the through-hole which penetrates the plate-shaped body 21 (holding tool main body 2) in the thickness direction. The support portion 22 constituted by the through-hole includes a large diameter portion 221 having the largest inner diameter, a small diameter portion 222 having the smallest inner diameter, and an inner diameter gradually decreasing portion 223 whose inner diameter gradually decreases from the back side to the front side. Yes. The large diameter portion 221 is located on the back side of the plate-like body 21, the small diameter portion 222 is located on the front side of the plate-like body 21, and the inner diameter gradually decreasing portion 223 is located between the large diameter portion 221 and the small diameter portion 222. To do.

  When the cap 9 is inserted into the support portion 22 from the back side of the plate-like body 21, the enlarged diameter portion 914 of the cap 9 is fitted into the large diameter portion 221. Thereby, the cap 9 can be supported from the outer peripheral side.

  Further, when the inner diameter gradually decreasing portion 223 comes into contact with the enlarged diameter portion 914 of the cap 9, the insertion limit of the cap 9 is restricted.

  As shown in FIG. 3, the same number of grooves 224 as the ribs 915 of the cap 9 are formed in the inner peripheral portion of the small diameter portion 222. Each groove 224 is formed along the vertical direction, and is arranged at equal intervals along the circumferential direction of the inner peripheral portion of the small diameter portion 222. When the cap 9 is inserted into the support portion 22, each rib 915 can engage with the groove 224. Thereby, as will be described later, when the holder main body 2 is gripped and the second connector 122 is screwed and connected to the cap 9 supported by the holder main body 2, the cap 9 is held by the holder main body. It is possible to prevent idling with respect to 2.

  Further, the cap 9 supported by the support portion 22 can be detached, that is, removed, by removing the cap 9 from the support portion 22 in the opposite direction.

  Thus, the support part 22 is comprised by the through-hole, Therefore The support and removal of the cap 9 can be performed easily.

  As shown in FIGS. 2 and 3, the finger hooks 23 are respectively provided on the left and right sides of the plate-like body 21 in the drawing. Both finger-hanging portions 23 protrude in opposite directions and are rounded. As a result, when the holder body 2 is gripped and the second connector 122 is screwed and connected to the cap 9 supported by the holder body 2, a finger can be hung on each finger hook portion 23. Therefore, the screwing can be easily performed.

  Further, when the holder 1 is taken out from the packaging material 30, the holder 1 can be pulled out as it is by putting a finger on the finger hook 23 or holding the finger hook 23 in the holder 1.

  Further, as shown in FIG. 8, when the second connector 122 is screwed and connected to the cap 9, when viewed from the upper side in the figure, each finger hook portion 23 of the holder body 2 and the second connector When the wings 124 of the connector 122 are combined (overlapped), it can be visually confirmed that the connection between the cap 9 and the second connector 122 is completed.

  The plate-like body 21 is formed with a thin portion 24 having a reduced thickness for weight reduction, and a rib 25 for reinforcing the thin portion 24 is also formed. The plate-like body 21 may have a constant thickness by omitting the thin portion 24.

  As shown in FIG. 5 and FIG. 6, the holder main body 2 further includes an operation unit 4 and a force applying unit 5 in addition to the plate-like body 21, and the plate-like body 21 and the operation unit 4. And the force applying portion 5 are integrally formed. The operation unit 4 is a part that performs a release operation for releasing the mounting state of the lid 3. The force imparting unit 5 is a part that imparts a force that presses the lid 3 in the attached state in a direction in which the lid 3 is detached from the holder main body 2.

  As shown in FIG. 3, the operation unit 4 includes a pair of operation pieces 41 that are cantilevered by the plate-like body 21. Each operation piece 41 is provided on the upper side and the lower side in the figure via the plate-like body 21. Each operation piece 41 has a fixed end 411 on the left side and a free end 412 on the right side in FIG. 3. As a result, the operation pieces 41 are elastically deformed in a direction of approaching and separating from each other. Since each operation piece 41 has the same configuration except that the arrangement location is different, a single operation piece 41 will be described below representatively.

  The operation piece 41 has a long shape and is a curved portion 413 in which the fixed end 411 side is curved in an arc shape. During the elastic deformation of the operation piece 41, the stress near the fixed end 411 is relieved by the curved portion 413. Thereby, the operation piece 41 can be elastically deformed stably.

  In addition, the free end 412 of the operation piece 41 is provided with a pressing portion 42 that presses the engaging portion 7 of the lid 3 on the front side of the holder 1 during a release operation for releasing the mounting state of the lid 3. Yes. The pressing part 42 protrudes toward the plate-like body 21 side. Moreover, the surface (pressing surface 421) which faces the plate-shaped body 21 of the pressing part 42 is rounded. On the pressing surface 421, the position in contact with the engaging portion 7 gradually changes slightly depending on the degree of deformation of the operation piece 41. For this reason, when the pressing surface 421 is rounded, the engaging portion 7 can be stably and reliably pressed regardless of the position where it comes into contact with the engaging portion 7.

  As shown in FIGS. 3, 5, and 6, a portion different from the pressing portion 42 of each operation piece 41 (operation portion 4), that is, between the pressing portion 42 and the bending portion 413 of each operation piece 41. The force giving part 5 is provided near the pressing part 42. The force imparting unit 5 is a part that imparts a force that presses the lid 3 in the mounted state in the direction of detaching from the holder body 2 before the mounted state of the lid 3 is released. As shown in FIG. 5, the force applying portion 5 protrudes toward the lid 3 side. Further, the force applying unit 5 has a pressing surface 51 that is inclined with respect to the direction in which the operation piece 41 is displaced, that is, the left-right direction in FIG. The force applying unit 5 having such a configuration approaches the lid 3 as the operation piece 41 is displaced, and the pressing surface 51 moves the lid 3 from the upper side to the lower side on the back side of the holder 1. Can be pressed. Thereby, the force which presses toward the direction which detach | leaves from the holder main body 2 is provided to the cover body 3 in a mounting state. Then, the lid 3 released from the engagement with the holder main body 2 is pressed downward as it is, and as a result, can be reliably detached from the holder main body 2 (see FIGS. 5 and 6). ).

  In addition, although the timing which the force provision part 5 provides force with respect to the cover body 3 was prior to the mounting state being released in this embodiment, the present invention is not limited to this. It may be simultaneously with the release. Such adjustment of the timing of applying the force can be performed, for example, by changing the difference between the protruding amount of the pressing portion 42 and the protruding amount of the force applying portion 5 when the holder 1 is designed.

  As shown in FIG. 4, the lid 3 is a back lid that is detachably attached to the holder body 2 and covers the opening 94 of the cap 9 in the attached state. This lid 3 can prevent airborne bacteria from adhering to the inside of the cap 9. Moreover, it can also prevent or suppress that the disinfecting liquid impregnated in the sponge 95 evaporates and the sponge 95 is dried.

  As shown in FIGS. 5 and 6, the lid 3 has a plate-like body 6 whose overall shape is plate-like, and an engaging portion 7 that can be engaged with the holder main body 2. And the engaging portion 7 are integrally formed.

  As shown in FIG. 3, the plate-like body 6 has substantially the same size as the plate-like body 21 of the holder body 2, and the whole overlaps with the plate-like body 21 when the lid body 3 is attached. Thereby, as shown in FIG. 4, the opening part 94 of the cap 9 supported by the holder main body 2 can be sufficiently covered. Therefore, even after taking out the cap 9 together with the holder 1 from the packaging material 30, it is possible to prevent airborne bacteria from adhering to the inside of the cap 9, which is preferable in terms of hygiene. The plate-like body 6 is a portion of the lid 3 to which a force is applied by the force applying unit 5 described above.

  As shown in FIG. 5, the engaging portion 7 is a portion that engages with the holder main body 2 and causes the lid 3 to take an attached state. The engaging portion 7 is composed of a pair of elastic pieces 71 protruding upward. Each elastic piece 71 is provided on each of the left and right sides of the plate-like body 6 in FIG. 5 corresponding to the pressing portion 42 of each operation piece 41. Each elastic piece 71 penetrates through the thin portion 24 of the holder body 2 in a state where it is engaged with the holder body 2.

  Claw portions 72 projecting in opposite directions are formed on the upper portions of the elastic pieces 71. Each claw 72 is engaged with the holder main body 2 from the front side, so that the lid 3 is prevented from being detached from the holder main body 2, so that the mounting state of being attached to the holder main body 2 is obtained.

  And in order to cancel | release the mounting | wearing state of the cover body 3, first, the both operation pieces 41 are collectively picked and pushed from the state shown in FIG. Thereby, the pressing portion 42 and the force applying portion 5 of each operation piece 41 approach the lid body 3, but before the pressing portion 42 presses the claw portion 72 of the elastic piece 71 of the lid body 3. The force applying portion 5 abuts on the plate-like body 6 of the lid 3 and applies a downward force. Thereafter, when both the operation pieces 41 are further pushed in, the elastic piece 71 is pressed against the elastic force while the downward force is applied to the lid 3 by the force applying portion 5. Can do. By the pressing against the elastic piece 71, the engagement of the claw portion 72 is released. The lid 3 is reliably detached from the holder body 2 as shown in FIG. 6 due to the combination of the disengagement of the claw part 72 and the downward force application by the force applying part 5. As a result, the opening 9 of the cap 9 is exposed and the second connector 122 can be connected.

  The releasing operation for releasing the mounting state of the lid 3 in this way is quickly performed by a simple operation of grasping and pushing both the operation pieces 41 together. Thus, the holder 1 can perform the releasing operation with one hand, and has excellent operability. The release operation is preferably performed in a state where the holder body 2 is positioned on the upper side and the lid body 3 is positioned on the lower side. Thereby, even if the lid body 3 is removed from the holder body 2, it is possible to prevent airborne bacteria from attaching to the inside of the cap 9. Each operation piece 41 (operation unit 4) is operated in a state where force is applied to the lid 3 by the force applying unit 5. Thereby, compared with the case where the engagement of the nail | claw part 72 is only cancelled | released, for example, the cover body 3 can be reliably removed.

  Next, an operation for connecting the cap 9 to the second connector 122 will be described with reference to FIGS.

  As shown in FIG. 7, in the holder 1, the lid 3 is removed from the holder body 2, and the cap 9 supported by the holder body 2 is in a state where the opening 94 is exposed. Yes. Further, the second connector 122 is in a state where the connection with the first connector 121 is released.

Then, as shown in FIG. 8, while the cap 9 is supported by the holder body 2, the cap 9 is moved closer to the second connector 122 and rotated in the direction of the arrow α ₉ . As a result, the cap 9 is screwed into the second connector 122. The rotation of the cap 9 is performed up to the screwing limit with respect to the second connector 122. Thereby, the cap 9 can be liquid-tightly connected to the second connector 122.

Next, as shown in FIG. 9, pulling the holder body 2 in the arrow alpha ₂ directions. As a result, the cap 9 is detached from the holder body 2 and the connection operation between the cap 9 and the second connector 122 is completed.

As described above, by using the holder 1 of the present invention, the cap 9 is connected to the second connector 122 (connector) before being detached from the holder body 2, and is connected to the second connector 122. Later, the holder body 2 is detached. In this case, by rotating the cap 9 in the arrow alpha ₉ direction, when going screwed into the second connector 122, by gripping the holder main body 2, it is possible to perform the screwing operation. As described above, the holder main body 2 functions as a gripping part that is gripped when being screwed into the second connector 122. As a result, the cap 9 can be easily and quickly connected to the second connector 122.

  As described above, when the cap 9 is inserted into the support portion 22 of the holder body 2, each rib 915 engages with the groove 224. As a result, when the holder body 2 is gripped and the cap 9 supported by the holder body 2 and the second connector 122 are screwed together, the cap 9 is idle with respect to the holder body 2. Can be surely prevented. Therefore, the cap 9 and the second connector 122 are screwed together so as to be securely connected.

  In addition, after the lid 3 is detached from the holder body 2, the cap 9 is detached from the holder body 2 in the same direction as the direction in which the lid 3 is detached. Making the removal direction of the lid 3 and the removal direction of the cap 9 uniform in the same direction contributes to improvement in operability of the holder 1, that is, ease of use.
