Technical Field

The present invention relates to a holder.

Background

In recent years, a treatment method by peritoneal dialysis has attracted attention for the reasons that the device and equipment are small and simple, the treatment cost is low, peritoneal adhesions can be prevented, and the burden on the patient is small, compared with a dialysis method by artificial kidney.

Among these Peritoneal Dialysis methods, particularly Continuous portable Peritoneal Dialysis (Continuous Peritoneal Dialysis) is receiving a lot of attention because a container (bag) of dialysate can be replaced by a patient himself/herself at home or at a work place.

In the 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. The pipes are connected to each other by connecting connectors provided at the ends of the pipes (see, for example, patent document 1). Further, patent document 1 discloses that a cap is temporarily attached to a connector connected to a patient-side tube before the connectors are connected to each other.

The cap includes a cap that is aseptically stored in a packaging bag in a state described below, for example. The cap is fixed to the base by fitting, and is stored in the packaging bag for each base. In the case of using the cap, the packaging bag is first opened, and then the cap is taken out for each stand and placed on, for example, a table. Then, the cap is pulled out from the pedestal with the right hand while the pedestal is pressed against the table top with the left hand, for example. The work of pulling out the cap with both hands as described above is a burden on the patient, and it takes time until the connectors are connected to each other. Depending on the degree of the force at the time of extraction, the cap may be in a posture in which sedimenting bacteria (falling bacteria) adhere to the inside thereof. Such attachment of sedimenting bacteria is not preferable in peritoneal dialysis.

Detailed Description

The holder of the present invention will be described in detail below based on preferred embodiments shown in the drawings.

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 a cap. Fig. 3 is a view seen from the direction of arrow a in fig. 2. Fig. 4 is a sectional view taken along line B-B of fig. 2. Fig. 5 is a cross-sectional view taken along line C-C of fig. 2. Fig. 6 is a vertical sectional view showing a state where the lid body is detached from the state shown in fig. 5. Fig. 7 to 9 are perspective views sequentially showing a process until the cap held by the holder of the present invention is attached to the connector. For convenience of description, the upper side in fig. 2, 4 to 9 is referred to as "upper (upper)" or "front side", and the lower side is referred to as "lower (lower)" or "back side".

The Peritoneal Dialysis set 100 shown in fig. 1 can be suitably used in, among Peritoneal Dialysis methods, especially a Continuous portable Peritoneal Dialysis (Continuous Peritoneal Dialysis) method in which a Dialysis solution is injected (supplied) into the Peritoneal cavity (i.e., into the abdominal cavity) of a patient and then the discharged solution of the Dialysis solution is recovered.

The peritoneal dialysis set 100 has: a dialysate bag 14 filled with dialysate in advance; a drain bag 19 for recovering the discharged dialysate; a bag side tube 11 connected to the dialysate bag 14 and the drain bag 19, respectively; an infusion tube 18 connected to a catheter (not shown) placed in the peritoneum of the patient; and a connector 12 for peritoneal dialysis for detachably connecting the bag-side tube 11 and the infusion tube 18. In addition, the peritoneal dialysis set 100 can also omit the dialysate bag 14 or drain bag 19, as desired.

In the peritoneal dialysis set 100, the bag-side tube 11, the infusion tube 18, and the connector 12 for peritoneal dialysis constitute a dialysis line 10 through which a dialysate (including a discharge liquid thereof) passes. The connector 12 for peritoneal dialysis includes a 1 st connector 121 and a 2 nd connector 122. By connecting the 1 st connector 121 and the 2 nd connector 122, the dialysate can be made to flow down from upstream to downstream in the dialysis line 10. Further, by releasing the connection between the 1 st connector 121 and the 2 nd connector 122, the middle of the dialysis line 10 can be separated. This enables, for example, replacement of the used dialysate bag 14 and/or the drain bag 19 with a new, i.e., unused dialysate bag 14 and/or drain bag 19.

The bag-side tube 11 includes a tube 111 for connecting the dialysate bag 14 to the 1 st connector 121 of the connector 12 for peritoneal dialysis, and a branch tube 112 branching off from the middle of the tube 111. The pipe 111 and the branch pipe 112 communicate with each other via a branch portion 113. The branch pipe 112 is connected to the drain bag 19 on the side opposite to the branch portion 113. In such a bag-side tube 11, a part thereof can be selectively closed to switch the flow path of the dialysate. In other words, in the bag-side tube 11, when the dialysate is supplied from the dialysate bag 14 to the patient side, the branch tube 112 is closed at a portion near the branch portion 113. When the discharged fluid is collected from the patient side into the fluid discharge bag 19, the branching portion 113 of the blocking tube 111 is located near the dialysate bag 14 side. The method of occluding the tube is not particularly limited, and for example, a method of attaching a drip clip (Klemme) to the tube to be occluded can be mentioned.

The 2 nd connector 122 of the connector for peritoneal dialysis 12 is connected to the infusion tube 18 on the side opposite to the patient side. The infusion tube 18 is provided with a connector 17 detachably connected to the middle thereof, and a roller clamp (roller clamp)16 for opening and closing the interior of the infusion tube 18 on the 2 nd connector 122 side of the connector 17.

In a connection released state in which the 1 st connector 121 and the 2 nd connector 122 are released from connection, the cap 9 is temporarily attached to the 2 nd connector 122. This is to prevent, for example, sedimentary bacteria from adhering to the 2 nd connector 122 while the connection-released state is established.

As shown in fig. 2, the cap 9 is packed in an unused state in a packing material 30, for example, in the form of a bag made of aluminum, to form a cap package 20. In addition, cap 9 is held by holder 1 within packaging material 30. The cap package 20 thus includes: a cap 9; a holder 1 holding a cap 9; and a packaging material 30 for packaging the caps 9 held by the holders 1 for each of the holders 1. When the cap 9 is attached to the 2 nd connector 122 and used, the cap 9 is removed from the packaging material 30 for each holder 1, and then the lid body 3 is detached from the holder body 2 and used.

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

First, the cap 9 is explained.

As shown in fig. 4, the cap 9 is formed in a cylindrical shape and has an opening 94 whose lower side (one end side) is open and an upper side wall 93 serving as a blocking portion which blocks the upper side (the other end side). In detail, the cap 9 has: an outer cylinder 91 formed in a cylindrical shape; an inner cylindrical portion 92 concentrically disposed inside the outer cylindrical portion 91 and formed in a cylindrical shape; and an upper side wall 93 connecting the outer cylinder 91 and the inner cylinder 92. The side opposite to the upper side wall 93 is an opening 94 that opens downward.

The outer tube portion 91 has an internal thread 912 formed in an inner peripheral portion 911 thereof. Thereby, the cap 9 can be connected to the male screw 123 of the 2 nd connector 122 by screwing (see fig. 7 to 9). Further, an enlarged diameter portion 914 having an enlarged outer diameter is formed at a lower portion of the outer peripheral portion 913 of the outer cylinder portion 91. The diameter-enlarged portion 914 has the largest outer diameter of the cap 9, i.e., the largest outer diameter. A plurality of convex strips 915 are formed in the outer circumferential portion 913 so as to protrude above the enlarged diameter portion 914 (see fig. 2, for example). The ribs 915 extend in the central axis direction of the outer tube 91, i.e., in the vertical direction, and are arranged at equal intervals in the circumferential direction of the outer tube 91. By forming such convex portions 915, when the cap 9 is screwed into the 2 nd connector 122, at least one convex portion 915 is engaged with a fingertip to facilitate rotation of the cap 9, and thus the screwing can be performed quickly.

The inner tube 92 has a shorter overall length than the outer tube 91 and is located on the upper wall 93 side. The inner diameter of the inner peripheral portion 921 of the inner cylindrical portion 92 changes in accordance with the shape of the 2 nd connector 122.

An annular seal 96 is supported and fixed to the inner cylindrical portion 92. In the state where the cap 9 and the 2 nd connector 122 are connected, the liquid-tightness therebetween is maintained by the seal 96, and thus, leakage can be prevented.

A sponge 95 impregnated with a disinfectant such as povidone iodine is inserted between the outer cylinder 91 and the inner cylinder 92 to the upper side wall 93. The end of the 2 nd connector 122 connected from the opening 94 of the cap 9 is brought into contact with the sponge 95 and sterilized.

The cap 9 thus configured is stored in the packaging material 30 in a sterilized state. The sterilization method is not particularly limited, but a method based on autoclaving is preferably used.

The holder 1 will be explained next.

As shown in fig. 2, the holder 1 holds the cap 9. The holder 1 includes two members, a holder body 2 and a cover 3 detachably attached to the holder body 2. The holder body 2 is a member for supporting the cap 9, and the lid body 3 is a member for covering the opening 94 of the cap 9 in a state of being attached to the holder body 2 (hereinafter referred to as an "attached state"). The constituent materials of the holder body 2 and the lid body 3 are not particularly limited, and various resin materials such as cyclic polyolefin and polyester are preferably used, for example, from the viewpoint of easy mold forming. In addition, various resin materials such as polypropylene, polycarbonate, polyacetal, and the like can be used in consideration of production cost, elasticity, and the like.

As shown in fig. 2 to 6, the holder body 2 has a plate-like body 21 formed in a plate-like shape as a whole. The thickness of the plate-like body 21 is smaller than the height of the cap 9. The plate-like body 21 is provided with a support portion 22 for supporting the cap 9, and a finger rest portion 23 for resting a finger of a user using the cap 9, for example.

The support portion 22 is provided at the center of the plate-like body 21. As shown in fig. 4, the support portion 22 is formed of a through-hole that penetrates the plate-like body 21 (holder body 2) in the thickness direction thereof. The support portion 22 constituted by the through-hole has: 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 having an inner diameter gradually decreasing from the back side toward the front side. 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 decreasing portion 223 is located between the large diameter portion 221 and the small diameter portion 222.

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. This enables the cap 9 to be supported from the outer peripheral side of the cap 9.

Further, the inner diameter gradually decreasing portion 223 abuts against the enlarged diameter portion 914 of the cap 9, whereby the insertion limit of the cap 9 is restricted.

As shown in fig. 3, the same number of grooves 224 as the ridges 915 of the cap 9 are formed in the inner periphery of the small-diameter portion 222. The grooves 224 are formed vertically and arranged at equal intervals along the circumferential direction of the inner circumferential portion of the small diameter portion 222. When the cap 9 is inserted into the support portion 22, each convex strip 915 can be engaged with the groove 224. As a result, as will be described later, when the holder body 2 is gripped and the 2 nd connector 122 is screwed into the cap 9 supported by the holder body 2 to connect, the cap 9 can be prevented from idling relative to the holder body 2.

In addition, the cap 9 supported by the support portion 22 can be detached, that is, detached, by pulling out the cap 9 from the support portion 22, in the opposite manner to the above.

In this way, the support portion 22 is formed by a through hole, and thus the cap 9 can be easily supported and detached.

As shown in fig. 2 and 3, the finger rest portions 23 are provided on the left and right sides of the plate-like body 21. The finger rest portions 23 on both sides protrude in opposite directions and have circular arcs. Accordingly, when the holder body 2 is gripped and the 2 nd connector 122 is screwed into the cap 9 supported by the holder body 2 to be connected, the fingers can be put on the respective finger-putting portions 23, and thus the screwing can be easily performed.

Further, when the holder 1 is taken out from the packaging material 30, the holder 1 can be directly pulled out by putting a finger on the finger rest portion 23 or pinching the finger rest portion 23 in the holder 1.

As shown in fig. 8, when the 2 nd connector 122 is screwed into the cap 9 and connected, the finger rest portions 23 of the holder body 2 and the wing portions 124 of the 2 nd connector 122 are in a mated (superposed) state when viewed from the upper side in the drawing, and thus the completion of the connection between the cap 9 and the 2 nd connector 122 can be visually confirmed.

In order to reduce the weight, the plate-like body 21 is formed with a thin portion 24 having a reduced thickness, and also with a rib 25 for reinforcing the thin portion 24. The plate-like body 21 may be formed to have a constant thickness without the thin portion 24.

As shown in fig. 5 and 6, the holder body 2 includes an operation portion 4 and a biasing portion 5 in addition to the plate-like body 21, and the plate-like body 21, the operation portion 4, and the biasing portion 5 are integrally formed. The operation unit 4 is a portion for performing a releasing operation for releasing the attached state of the lid body 3. The urging portion 5 is a portion that applies a force that urges the lid body 3 in the attached state in a direction to detach from the holder main body 2.

As shown in fig. 3, the operation portion 4 is constituted by a pair of operation pieces 41 supported by the plate-like body 21 in a cantilever manner. The operation pieces 41 are provided on the upper and lower sides in the drawing with the plate-like body 21 interposed therebetween. Each of the operation pieces 41 has a fixed end 411 on the left side and a free end 412 on the right side in fig. 3. Thereby, the operation pieces 41 are elastically deformed in the directions of approaching and separating from each other. Since each operation piece 41 has the same configuration except for the different arrangement position, one operation piece 41 will be described as a representative example below.

The operation piece 41 is formed in an elongated shape, and the fixed end 411 side is a curved portion 413 curved in an arc shape. When the operation piece 41 is elastically deformed, the stress near the fixed end 411 is relaxed by the bent portion 413. This allows the operation piece 41 to be elastically deformed stably.

Further, at the free end 412 of the operation piece 41, a pressing portion 42 is provided which presses the engaging portion 7 of the cover 3 on the front surface side of the holder 1 when a releasing operation for releasing the attached state of the cover 3 is performed. The pressing portion 42 protrudes toward the plate-like body 21 side. Further, the surface (pressing surface 421) of the pressing portion 42 facing the plate-like body 21 is rounded. On the pressing surface 421, the position of contact with the engaging portion 7 changes, although slightly, depending on the degree of deformation of the operation piece 41. Therefore, by rounding the pressing surface 421, the engaging portion 7 can be stably and reliably pressed regardless of the position of contact with the engaging portion 7.

As shown in fig. 3, 5, and 6, the urging portion 5 is provided at the portion of each operation piece 41 (operation portion 4) different from the pressing portion 42, that is, between the pressing portion 42 and the bent portion 413 of each operation piece 41 and at the pressing portion 42. The urging portion 5 is a portion that applies a force that urges the lid body 3 in the attached state in a direction to detach from the holder main body 2 before the attached state of the lid body 3 is released. As shown in fig. 5, the urging portion 5 protrudes toward the lid 3 side. The biasing portion 5 has a pressing surface 51 inclined with respect to the direction in which the operation piece 41 is displaced, i.e., the left-right direction in fig. 5. The biasing portion 5 configured as described above approaches the lid body 3 in accordance with the displacement of the operation piece 41, and the pressing surface 51 can press the lid body 3 from the upper side toward the lower side on the back side of the holder 1. This applies a force to the lid 3 in the attached state in a direction to detach from the holder body 2. Then, the lid body 3 released from the engagement with the holder main body 2 is directly pressed downward, and as a result, can be reliably detached from the holder main body 2 (see fig. 5 and 6).

In the present embodiment, the timing at which the urging portion 5 urges the lid body 3 is before the removal of the attached state, but the present invention is not limited to this, and may be the same timing as the removal of the attached state, for example. Such adjustment of the timing of the application of the force can be achieved by, for example, changing the difference between the amount of projection of the pressing portion 42 and the amount of projection of the urging portion 5 when designing the holder 1.

As shown in fig. 4, the lid body 3 is a back cover that is detachably attached to the holder body 2 and covers the opening 94 of the cap 9 in the attached state. The lid 3 prevents airborne microorganisms from adhering to the inside of the cap 9. In addition, it is also possible to prevent or suppress the sponge 95 from drying due to evaporation of the disinfectant impregnated in the sponge 95.

As shown in fig. 5 and 6, the lid 3 has a plate-like body 6 formed in a plate-like shape as a whole and an engaging portion 7 engageable with the holder body 2, and the plate-like body 6 and the engaging portion 7 are formed integrally.

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 in the attached state of the lid body 3, the whole body overlaps the plate-like body 21. As a result, as shown in fig. 4, the opening 94 of the cap 9 supported by the holder body 2 can be sufficiently covered. This prevents airborne bacteria from adhering to the inside of the cap 9 even after the cap 9 is removed from the packaging material 30 for each holder 1, which is preferable from a hygienic viewpoint. The plate-like body 6 is a portion to which a force is applied by the above-described biasing portion 5 in the lid body 3.

As shown in fig. 5, the engaging portion 7 is a portion that engages with the holder body 2 to bring the cover 3 into an attached state. The engaging portion 7 is formed of a pair of elastic pieces 71 projecting upward. The elastic pieces 71 are provided on the left and right sides of the plate-like body 6 in fig. 5, corresponding to the pressing portions 42 of the operation pieces 41. Each elastic piece 71 penetrates the thin portion 24 of the holder body 2 in a state of being engaged with the holder body 2.

Claw portions 72 protruding in opposite directions are formed on the upper portions of the elastic pieces 71. Each claw portion 72 is engaged with the holder main body 2 from the front side, thereby preventing the lid body 3 from being detached from the holder main body 2, and thus being in an attached state to the holder main body 2.

Then, to release the attached state of the lid body 3, first, both the operation pieces 41 are pinched and pushed in at once from the state shown in fig. 5. Thus, the pressing portion 42 and the biasing portion 5 of each operation piece 41 approach the lid body 3, but the biasing portion 5 abuts against the plate-like body 6 of the lid body 3 and applies a downward force before the pressing portion 42 presses the claw portion 72 of the elastic piece 71 of the lid body 3. When both the operation pieces 41 are further pushed in, the elastic piece 71 can be pressed against the elastic force of the elastic piece 71 while the lid body 3 is applied with a downward force by the biasing portion 5. The engagement of the claw portion 72 is released by pressing the elastic piece 71. The lid body 3 is reliably separated from the holder main body 2 as shown in fig. 6 by the complementary action of the release of the engagement of the claw portion 72 and the application of the downward force by the urging portion 5. Thereby, the opening 94 of the cap 9 is exposed, and the 2 nd connector 122 can be connected.

In this way, the releasing operation for releasing the attached state of the lid body 3 is quickly performed by a simple operation of pressing both the operation pieces 41 together. The holder 1 can be released with one hand in this manner, and is excellent in operability. The releasing 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. This prevents airborne microorganisms from adhering to the inside of the cap 9 even when the lid 3 is detached from the holder body 2. Each operation piece 41 (operation portion 4) is operated in a state where a force is applied to the lid body 3 by the biasing portion 5. This enables the lid 3 to be reliably disengaged, for example, compared to the case where only the engagement of the claw portions 72 is released.

Next, an operation of connecting the cap 9 to the 2 nd connector 122 will be described with reference to fig. 7 to 9.

As shown in fig. 7, the lid body 3 of the holder 1 is detached from the holder body 2, and the cap 9 supported by the holder body 2 is in a state in which the opening 94 is exposed. The 2 nd connector 122 is disconnected from the 1 st connector 121.

Then, as shown in fig. 8, the cap 9 is brought close to the 2 nd connector 122 while being supported by the holder main body 2, and is moved along arrow α₉The direction is rotated. Thereby, the cap 9 is screwed with the 2 nd connector 122. Further, the cap 9 is rotated to the screwing limit with respect to the 2 nd connector 122. This enables the cap 9 and the 2 nd connector 122 to be connected liquid-tightly.

Next, as shown in FIG. 9, the holder body 2 is moved toward the arrow α₂And (4) pulling in the direction. Thereby, the cap 9 is disengaged from the holder body 2, and the connection operation of the cap 9 to the 2 nd connector 122 is completed.

As described above, by using the holder 1 of the present invention, the cap 9 is connected to the 2 nd connector 122 (connector) before being disconnected from the holder main body 2, and is disconnected from the holder main body 2 after being connected to the 2 nd connector 122. In this case, cap 9 is moved along arrow α₉When the direction is rotated and the 2 nd connector 122 is screwed, the holder body 2 can be held and the screwing operation can be performed. In this manner, the holder main body 2 functions as a grip portion to be gripped when the 2 nd connector 122 is screwed. This makes it possible to easily and quickly connect the cap 9 to the 2 nd connector 122.

As described above, when the cap 9 is inserted into the support portion 22 of the holder main body 2, the respective convex strips 915 engage with the grooves 224. Thus, when the holder body 2 is gripped and the cap 9 supported by the holder body 2 and the 2 nd connector 122 are screwed, the cap 9 can be reliably prevented from idling relative to the holder body 2. Thus, the cap 9 and the 2 nd connector 122 are appropriately screwed to connect them reliably.

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 detachment direction of the lid 3. Making the detaching direction of the lid body 3 and the detaching direction of the cap 9 uniform in the same direction contributes to the operability of the holder 1, that is, improves the ease of use.

The holder of the present invention has been described above with respect to the illustrated embodiment, but the present invention is not limited thereto, and each part constituting the holder can be replaced with any structure that can exhibit the same function. In addition, any structure may be added.

Further, the operation portion for performing the releasing operation for releasing the attached state of the lid body is the structure of the holder main body in the above embodiment, but is not limited thereto, and may be the structure of the lid body.

In addition, the engaging portion for bringing the cover into the attached state is the structure of the cover in the above-described embodiment, but is not limited to this, and may be the structure of the holder main body.

In the above embodiment, the engaging portion is formed by two elastic pieces, but the number of the elastic pieces is not limited thereto, and may be one, three or more, for example.
