Abstract
Description
Technical Field
[0001] This invention relates to the field of peritoneal dialysis auxiliary devices, specifically to a peritoneal dialysis fluid bag outlet plug breakage assist device. Background Technology
[0002] Peritoneal dialysis is one of the current methods for treating end-stage renal disease. It utilizes the semi-permeable membrane properties of the patient's own peritoneum to regularly and periodically infuse dialysis fluid into the peritoneal cavity through the principles of diffusion and convection, and remove waste fluid from the body. This method aims to remove retained metabolic products, correct electrolyte and acid-base imbalances, and ultrafilter excess water, thus serving as a renal replacement therapy.
[0003] Peritoneal dialysis bags containing dialysis fluid have an outlet plug at the opening for sealing. During peritoneal dialysis, this outlet plug needs to be broken to release the dialysis fluid into the infusion tubing. Currently, the outlet plug is usually broken manually. This method requires the operator to use both hands: one hand holds the connector between the peritoneal dialysis bag and the outlet plug, while the other hand forcefully breaks the outlet plug. However, because peritoneal dialysis patients are often frail, especially elderly patients, it is difficult for them to quickly and effectively break the outlet plug completely. This results in incomplete breakage of the outlet plug, restricted dialysis fluid release, and consequently, difficulties in performing peritoneal dialysis smoothly. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention proposes a peritoneal dialysis bag outlet plug breakage aid to solve the problem that patients currently have difficulty manually and quickly breaking the outlet plug completely, resulting in incomplete disconnection of the outlet plug, restricted dialysis fluid release, and consequently, difficulty in performing peritoneal dialysis smoothly.
[0005] The objective of this invention is achieved through the following technical solution:
[0006] The present invention provides a peritoneal dialysis bag outlet plug breakage aid, comprising:
[0007] The main column has a laterally extending positioning block at one end and a sliding groove on the side facing that side, with a through groove on the lower side of the sliding groove.
[0008] A bending assembly includes a slide bar, an extension block, and a push post. The slide bar is slidably mounted in a groove along a direction approaching or away from a positioning block. The extension block is slidably mounted in a through groove, with its top end connected to the slide bar. The bottom end of the extension block extends downward into the through groove and is provided with a push post, so that the sliding path of the push post is vertically offset from that of the positioning block. One end of the push post extends towards the positioning block, and this extended end is provided with a first push block. One end of the first push block extends towards the extending direction of the positioning block.
[0009] Control components, which are used to drive the slider to slide back and forth.
[0010] Furthermore, the slider has an inwardly extending buffer hole at one end facing the positioning block. A buffer slide post is slidably installed in the buffer hole. The buffer slide post is connected to the bottom of the buffer hole by a first elastic element. The first elastic element can provide an elastic force to push the buffer slide post out of the buffer hole. The outer end of the buffer slide post extends out of the buffer hole and is provided with a clamping block. One end of the clamping block extends in the extending direction of the positioning block.
[0011] Furthermore, the outer edges of the positioning block and the clamping block facing each other are both inclined surfaces.
[0012] Furthermore, a rack is provided on the side of the slide bar facing outward from the slide groove. The control component includes a hinge seat and a rotating handle. The hinge seat is provided on the path of the main column located on both sides of the slide groove. A toothed ring is provided at one end of the rotating handle. The toothed ring is axially rotatably connected to the hinge seat and is connected to the rack for transmission.
[0013] Furthermore, a second elastic element is connected between the end of the slide bar away from the positioning block and the inner wall of the slide groove. The second elastic element can provide an elastic force to move the slide bar away from the positioning block.
[0014] Furthermore, it also includes a reverse bending assembly, which includes a support column, a sleeve, and a push rod. The support column is installed on the bottom side of the corresponding positioning block of the main column and extends downward. The sleeve is axially rotatably fitted onto the support column. A push plate is provided on the side of the sleeve away from the positioning block, and a second push block is provided on the side of the sleeve close to the positioning block. The second push block is located below the push plate, and the push plate is located on the sliding path of the push column. The push rod is provided on the first push block and extends toward the push plate.
[0015] Furthermore, a torsion spring is installed between the sleeve and the inside of the support column. In the initial state, the push plate abuts against the end of the push rod, and the second push block is directly below the positioning block.
[0016] Furthermore, the positioning block, clamping block, first push block, and second push block are all provided with protective pads on the sides facing each other.
[0017] As can be seen from the above technical solution, the peritoneal dialysis bag outlet plug breaking aid provided by the present invention replaces the manual breaking method of the outlet plug. By using a control component to drive the breaking component to move as a whole, the positioning blocks of different heights and the first push block apply shearing forces in opposite directions to the outlet plug, forcing it to break completely. The clamping block with a buffer function can clamp the connector above the outlet plug to prevent slippage during operation, and can also not hinder the movement of the first push block. The reverse breaking component applies a reverse pushing force to the outlet plug again, which can further ensure that the outlet plug is completely broken. The clamping process, the breaking process and the reverse breaking process can be performed simultaneously, which is convenient and quick to operate, and can be completed in one step.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.
[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0030] like Figures 1-3 As shown, this embodiment provides a peritoneal dialysis bag outlet plug breakage assist device, which includes a main column 1, a breakage assembly 2, and a control assembly 3.
[0031] Please see Figures 1-3 One end of the main column 1 is provided with a laterally extending positioning block 11 and the main column 1 is provided with a sliding groove 12 facing this side. The positioning block 11 is used to abut against the peritoneal dialysis bag connector connected above the outlet plug, and a through groove 13 is provided on the lower side of the sliding groove 12.
[0032] The breaking assembly 2 includes a slide bar 21, an extension block 22, and a push post 23. The slide bar 21 is slidably installed in the groove 12 along the direction of approaching or away from the positioning block 11. The extension block 22 is slidably installed in the through groove 13, and its top end is connected to the slide bar 21. The bottom end of the extension block 22 extends downward into the through groove 13 and is provided with a push post 23, so that the sliding path of the push post 23 is vertically offset from that of the positioning block 11. One end of the push post 23 extends towards the positioning block 11, and a first push block 24 is provided at this extended end. One end of the first push block 24 extends towards the extension direction of the positioning block 11. The first push block 24 can push the outlet plug towards the positioning block 11, so that the positioning block 11 and the first push block 24 respectively apply pressure on the side of the connector opposite to the outlet plug, forming a shearing force and forcing the outlet plug to break. A rack 215 is provided on the side of the slide bar 21 facing out of the groove 12.
[0033] Furthermore, the slide bar 21 has an inwardly extending buffer hole 211 at one end facing the positioning block 11. A buffer slide post 212 is slidably installed in the buffer hole 211. The buffer slide post 212 is connected to the bottom of the buffer hole 211 through a first elastic member 213. The first elastic member 213 can provide an elastic force to push the buffer slide post 212 out of the buffer hole 211. The outer end of the buffer slide post 212 extends out of the buffer hole 211 and is provided with a clamping block 214. One end of the clamping block 214 extends in the extending direction of the positioning block 11, and the clamping block 214 is flush with the positioning block 11.
[0034] In practical use, the clamping block 214 can move along with the slide bar 21. The clamping block 214 and the positioning block 11 can clamp and hold the connector above the outlet plug, preventing slippage during the process of the first push block 24 breaking off the outlet plug. When the first push block 24 continues to move with the slide bar 21 to push the outlet plug, the buffer slide bar 212 will slide into the buffer hole 211 by pressing the first elastic element 213. Under the elastic force of the first elastic element 213, the clamping block 214 can continuously clamp the connector, while performing a certain degree of contraction and buffering to prevent interference with the movement of the first push block 24. It is worth noting that it is more reasonable to clamp the connector with the clamping block 214 first, and then break off the outlet plug with the first push block 24. Therefore, in the initial state, the horizontal straight-line distance between the clamping block 214 and the positioning block 11 should not exceed the horizontal straight-line distance between the first push block 24 and the positioning block 11. Preferably, the horizontal straight-line distance between the clamping block 214 and the positioning block 11 is the same as the horizontal straight-line distance between the first push block 24 and the positioning block 11, which helps to reduce the elastic force of the first elastic element 213 that needs to be overcome when moving the slider 21.
[0035] To facilitate quick insertion of the peritoneal dialysis bag opening connector between the clamping block 214 and the positioning block 11 during operation, preferably, the outer edges of the positioning block 11 and the clamping block 214 facing each other are inclined surfaces to provide a guiding effect.
[0036] The control component 3 is used to drive the slider 21 to slide back and forth in order to control the first push block 24 to push the outlet plug.
[0037] like Figures 1-3 As shown, in one embodiment, the control component 3 includes a hinge 31 and a rotating handle 32. The hinge 31 is disposed on the path of the main column 1 located on both sides of the slide groove 12. One end of the rotating handle 32 is provided with a gear ring 321, which is axially rotatably connected to the hinge 31 and drivenly connected to the rack 215. In this embodiment, by squeezing the main column 1 and the rotating handle 32, the gear ring 321 drives the rack 215 to move, thereby controlling the movement of the slide bar 21. This method is simple and labor-saving to operate, easy for users to operate, and has low manufacturing cost. It should be noted that when the rotating handle 32 and the main column 1 are squeezed to the bottom, the first push block 24 and the positioning block 11 will be staggered to ensure that the outlet plug is completely broken.
[0038] Preferably, a second elastic element 216 is connected between the end of the slide bar 21 away from the positioning block 11 and the inner wall of the slide groove 12. The second elastic element 216 can provide an elastic force to move the slide bar 21 away from the positioning block 11. When the slide bar 21 moves away from the positioning block 11, it will drive the rotating handle 32 to reopen through the rack 215 and the gear ring 321, which is convenient for the next use.
[0039] Of course, for greater ease and convenience, in another embodiment, the control component 3 may be a motor (not shown), which is mounted on the main column 1 and has a gear at its motor shaft end, which is connected to the rack 215 for transmission.
[0040] Both the first elastic element 213 and the second elastic element 216 can be springs.
[0041] Please see Figure 1 and Figure 2 To further ensure that the outlet plug can be completely broken off, in one embodiment, a reverse breaking assembly 4 is also included, which includes a support column 41, a sleeve 42 and a push rod 43. The support column 41 is installed on the bottom side of the main column 1 corresponding to the positioning block 11 and extends downward. The sleeve 42 is axially rotatably fitted on the support column 41. A push plate 421 is provided on the side of the sleeve 42 away from the positioning block 11, and a second push block 422 is provided on the side of the sleeve 42 close to the positioning block 11. The second push block 422 is located below the push plate 421 and the push plate 421 is located on the sliding path of the push column 23. The push rod 43 is provided on the first push block 24 and extends toward the push plate 421. In practical use, the push rod 43 can move along with the slide bar 21. When the first push block 24 pushes towards the outlet plug, the push rod 43 will push the push plate 421 to reverse the sleeve 42, thereby enabling the second push block 422 to turn towards the side closer to the first push block 24. Since the position of the first push block 24 is lower than the position of the positioning block 11, and the position of the second push block 422 is lower than the position of the first push block 24, two shearing forces will be formed on the outlet plug, making the outlet plug easier to break.
[0042] Furthermore, a torsion spring is installed between the sleeve 42 and the inside of the support column 41. In the initial state, the push plate 421 abuts against the end of the push rod 43, and the second push block 422 is directly below the positioning block 11, which is conducive to inserting the outlet plug between the first push block 24 and the second push block 422.
[0043] To prevent the positioning block 11, clamping block 214, first push block 24 and second push block 422 from squeezing the infusion tubing and causing damage to the equipment, preferably, the positioning block 11, clamping block 214, first push block 24 and second push block 422 are all provided with protective pads on the sides facing each other. The protective pads are rubber pads or silicone pads.
[0044] The present invention provides a peritoneal dialysis bag outlet plug breakage assist device. In specific use, the connector of the peritoneal dialysis bag opening is placed inside the positioning block 11. The rotating handle 32 is pinched, which moves the driving slide 21 toward the positioning block 11. At the same time, the clamping block 214 and the first push block 24 move toward the positioning block 11. After the clamping block 214 contacts the connector, it clamps the connector between the clamping block 214 and the positioning block 11. The sliding slide 21 continues to move, which causes the buffer slide 212 to retract into the buffer hole 211 for buffering. At the same time, the first push block 24 continues to move and pushes the outlet plug to force it to break. The lower end of the outlet plug will be tilted away from the first push block 24 under the push of the first push block 24. When the first push block 24 moves, the push rod 43 pushes the push plate 421 to drive the second push block 422 to reverse. The second push block 422 will push the tilted end below the outlet plug in the opposite direction, further forcing the outlet plug to break, thereby achieving complete breakage of the outlet plug.
[0045] This invention replaces the manual breaking of the outlet plug. By using the control component 3 to drive the bending component 2 to move as a whole, the positioning blocks 11 of different heights and the first push block 24 apply shearing forces in opposite directions to the outlet plug, forcing it to break completely. The clamping block 214 with a buffer function can clamp the connector above the outlet plug to prevent slippage during operation, and can also not hinder the movement of the first push block 24. The reverse bending component 4 applies a reverse pushing force to the outlet plug again, which can further ensure that the outlet plug is completely broken. The clamping process, the bending process and the reverse bending process can be carried out simultaneously, making the operation convenient, quick and easy, and done in one step.
[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
