Description

Technical Field

[0001] This invention relates to the field of peritoneal dialysis technology, specifically to a peritoneal dialysis device with controllable flow rate. Background Technology

[0002] Peritoneal dialysis uses the peritoneum as an exchange space and the peritoneum as a semipermeable membrane to remove toxins and excess water from the body, thus achieving the goal of treatment. Due to its safety, convenience, simplicity, and speed, it has become one of the important treatment methods for end-stage renal disease (ESRD). During peritoneal dialysis treatment, establishing a patent and effective peritoneal dialysis tubing is crucial for the smooth progress of dialysis. However, complications after peritoneal dialysis catheter placement lead to approximately 20% of patients switching to hemodialysis, which is a significant factor affecting catheter-related survival after peritonitis.

[0003] A search revealed a peritoneal dialysis device, such as the one disclosed in patent publication CN117797350A, which includes a dialysis tube, a three-way connector, a peritoneal dialysis bag, a waste fluid bag, and a positioning structure. The dialysis tube is connected to the peritoneal dialysis bag and the waste fluid bag through the three-way connector. The end of the dialysis tube away from the three-way connector is the insertion end. Multiple dialysis holes are spaced apart on the tube wall of the insertion end. The positioning structure includes a driving component and a positioning component. The positioning component is columnar and is sleeved on the insertion end.

[0004] The aforementioned patent documents effectively address the drift problem of peritoneal dialysis catheters inserted into peritoneal dialysis patients. However, certain drawbacks remain during use. For example, the uniform inner diameter of the three-way stopcocks makes it inconvenient for users to control the flow rate of the dialysate, leading to pain in some patients. Furthermore, the internal structure of these three-way stopcocks lacks components for quick switching between drainage and dialysate injection, resulting in poor operability. Therefore, a peritoneal dialysis device with controllable flow rate is urgently needed to solve these problems. Summary of the Invention

[0010] Preferably, a support frame is fixedly installed on the lower part of the side wall of the adjusting cylinder on both the left and right sides, and a positioning seat is fixedly installed at the lower end of the support frame on both the left and right sides.

[0011] Preferably, the crushing mechanism includes a transmission rod fixedly installed on the inner wall of the guide impeller cavity. The transmission rod is connected through to an adjusting rod and an adjusting sleeve. A rotating disk is slidably installed on the right side of the transmission rod's side wall.

[0013] Preferably, the positioning sleeve and the crushing blade are arranged in several sets at equal intervals in a ring on the side wall of the rotating disk, and a limit groove is opened on the inner cavity side wall of the rotating disk. A limit strip is slidably installed in the inner cavity of the limit groove, and the limit strip is fixedly installed on the side wall of the transmission rod.

[0014] Preferably, the guiding mechanism includes a drainage pipe fixedly installed on the left side of the side wall of the outlet pipe and a guide pipe fixedly installed on the right side of the side wall of the outlet pipe.

[0015] Preferably, the connecting rod is rotatably connected to the liquid outlet pipe, a buffer groove is provided on the side wall of the sealing seat, a buffer plate is slidably installed in the inner cavity of the buffer groove, a buffer spring is fixedly installed on the side wall of the buffer plate, the other end of the buffer spring is fixedly installed on the bottom surface of the inner cavity of the buffer groove, arc-shaped baffles are fixedly installed on both the left and right sides of the side wall of the sealing seat, and through holes are provided on the side walls of both the sealing seat and the buffer plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, the user can use a hex wrench inserted into the internal hexagonal slot to rotate the drive rod. At this time, the drive bevel gear fixed on its side wall can drive the transmission bevel gear to rotate. The transmission bevel gear is slidably connected to the adjusting rod, and the adjusting rod is threadedly connected to the adjusting sleeve. Under the limiting action of the second bracket on the adjusting sleeve, the adjusting rod will continuously move towards the inner cavity of the adjusting sleeve, so that the distance between the guide impeller and the inlet pipe changes. Since the guide impeller is conically set at the outlet of the inlet pipe, the fluid flow rate entering the adjusting cylinder from the inlet pipe will change, so that the entire device realizes the function of controlling the input and output flow of peritoneal dialysis, improving the practicality of the entire device.

[0018] 2. In this invention, when the entire device is used for drainage, as the fluid continuously enters the inner cavity of the regulating cylinder from the inlet pipe, the fluid passes through the guide impeller. The first impeller blade and the second impeller blade are fixedly installed on the side wall of the guide impeller. At this time, the fluid can drive the guide impeller to rotate the transmission rod fixed in its inner cavity. The transmission rod can drive the rotating disk to rotate. At this time, through the setting of the crushing blade in the inner cavity of the positioning sleeve, the crushing blade rotates continuously and can break the scab in the fluid, so as to reduce the possibility of blockage when the subsequent fluid enters the drainage bag.

[0019] 3. In this invention, when using the device, the user can rotate the connecting rod by using the handle. Since the connecting rod is fixedly connected to the outlet pipe, the sealing seat will drive the arc-shaped baffle to rotate to the lower part of the side wall of the outlet pipe, thereby blocking the drainage pipe. When the arc-shaped baffle rotates to the upper part of the side wall of the outlet pipe, it will block the guide pipe. Thus, through the above-mentioned means, this device can quickly realize the conversion of the flow channel, greatly improving the work efficiency of medical staff. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6This invention provides a technical solution for a peritoneal dialysis device with controllable flow rate: it includes an adjusting cylinder 1, which is arranged in two sections. Connecting rings 2 are slidably installed on the side walls of the two adjusting cylinders 1. An inlet pipe 3 is fixedly installed on the left end face of the adjusting cylinder 1, and an outlet pipe 4 is fixedly installed on the right end face of the adjusting cylinder 1. A first support 5 is fixedly installed in the inner cavity of the left adjusting cylinder 1, and an adjusting mechanism 6 is provided in the inner cavity of the first support 5. A second support 7 is fixedly installed in the inner cavity of the right adjusting cylinder 1. A crushing mechanism 8 is provided on the right side of the inner cavity of the adjusting cylinder 1. A conducting mechanism 9 is provided in the inner cavity of the outlet pipe 4. Support frames 12 are fixedly installed on the lower part of the side walls of the left and right adjusting cylinders 1, and positioning seats 13 are fixedly installed at the lower ends of the support frames 12 on both sides.

[0029] Furthermore, the adjustment mechanism 6 includes an adjustment rod 61 rotatably mounted in the inner cavity of the first bracket 5, and a guide impeller 62 rotatably mounted on the left side wall of the adjustment rod 61. A transmission bevel gear 63 is slidably mounted on the side wall of the adjustment rod 61, a drive rod 64 is rotatably mounted on the side wall of the connecting ring 2, a drive bevel gear 65 is fixedly mounted on the output shaft end of the drive rod 64, and an adjustment sleeve 66 is fixedly mounted in the inner cavity of the second bracket 7.

[0030] The guide impeller 62 is located at the outlet of the liquid inlet pipe 3. A first impeller blade 621 and a second impeller blade 622 are fixedly installed on the side wall of the guide impeller 62. The first impeller blade 621 and the second impeller blade 622 are arranged alternately. The chord length of the first impeller blade 621 is greater than the chord length of the second impeller blade 622. The first impeller blade 621 and the second impeller blade 622 are both inclined on the side wall of the guide impeller 62. The guide impeller 62 is conical. The liquid inlet side of the left regulating cylinder 1 is designed as a conical section.

[0031] The transmission bevel gear 63 is meshed with the drive bevel gear 65. The drive rod 64 has an internal hexagonal groove 641 on its side wall. The adjusting rod 61 is threadedly connected to the adjusting sleeve 66. An annular block 21 is fixedly installed on the inner side wall of the connecting ring 2. An annular groove 11 is opened on the side wall of the adjusting cylinder 1 on both sides. The annular block 21 slides in the inner cavity of the annular groove 11.

[0032] It should be noted that the transmission bevel gear 63 and the adjusting rod 61 are connected in a manner similar to a key (i.e., a key is provided on the outer periphery of the adjusting rod 61, and a keyway matching the key is provided on the inner side wall of the transmission bevel gear 63, with the key and keyway slidably connected). This ensures that the transmission bevel gear 63 can slide axially relative to the adjusting rod 61, but cannot rotate circumferentially, thus ensuring that the rotation of the transmission bevel gear 63 drives the adjustment rod 61 to rotate. In addition, the position of the transmission bevel gear 63 relative to the adjusting cylinder 1 remains unchanged (for example, a sleeve can be connected to the inner side wall of the connecting ring 2 at the position corresponding to the transmission bevel gear 63 via a vertical rod, and the transmission bevel gear 63 is rotatably connected to the sleeve via a bearing). The transmission bevel gear 63 cannot move with the movement of the adjusting rod 61. Under the limiting action of the first bracket 5 on the adjusting rod 61, the position of the transmission bevel gear 63 remains unchanged, ensuring that the transmission bevel gear 63 can always maintain meshing with the driving bevel gear 65. A sealing ring is provided at the connection between the connecting ring 2 and the two adjusting cylinders 1 to ensure the seal between the two adjusting cylinders 1.

[0033] It should be noted that the user can use a hex wrench inserted into the internal hexagonal slot 641 to rotate the drive rod 64. At this time, the drive bevel gear 65 fixed on its side wall can drive the transmission bevel gear 63 to rotate. The transmission bevel gear 63 is slidably connected to the adjusting rod 61, and the adjusting rod 61 is threadedly connected to the adjusting sleeve 66. Under the limiting action of the second bracket 7 on the adjusting sleeve 66, the adjusting rod 61 will continuously move towards the inner cavity of the adjusting sleeve 66, so that the distance between the guide impeller 62 and the inlet pipe 3 changes. Since the guide impeller 62 is conically set at the outlet of the inlet pipe 3, the fluid flow rate entering the regulating cylinder 1 from the inlet pipe 3 will change, so that the entire device realizes the function of controlling the input and output flow of peritoneal dialysis, improving the practicality of the entire device.

[0034] Furthermore, the crushing mechanism 8 includes a transmission rod 81 fixedly installed on the inner wall of the guide impeller 62. The transmission rod 81 is connected through the adjusting rod 61 and the adjusting sleeve 66. A rotating disk 82 is slidably installed on the right side of the side wall of the transmission rod 81. A positioning sleeve 83 is fixedly installed on the side wall of the rotating disk 82. A crushing blade 84 is slidably installed in the inner cavity of the positioning sleeve 83.

[0035] A positioning plate 85 is fixedly installed on the side wall of the crusher 84, and a centrifugal spring 86 is fixedly installed on the side wall of the positioning plate 85. The other end of the centrifugal spring 86 is fixedly installed on the bottom surface of the inner cavity of the positioning sleeve 83. The rotating disk 82 is rotatably connected to the adjusting sleeve 66.

[0036] The positioning sleeve 83 and the crushing blade 84 are arranged in a ring at equal intervals on the side wall of the rotating disk 82. A limit groove 821 is opened on the inner cavity side wall of the rotating disk 82. A limit strip 811 is slidably installed in the inner cavity of the limit groove 821. The limit strip 811 is fixedly installed on the side wall of the transmission rod 81.

[0037] It should be noted that during the entire device's drainage operation, as fluid continuously enters the inner cavity of the regulating cylinder 1 from the inlet pipe 3, the fluid passes through the guide impeller 62. The first impeller blade 621 and the second impeller blade 622 are fixedly installed on the side wall of the guide impeller 62. At this time, the fluid drives the guide impeller 62, causing the transmission rod 81 fixed within its inner cavity to rotate. The transmission rod 81 then drives the rotating disk 82 to rotate. Due to the placement of the crushing blade 84 within the positioning sleeve 83, the continuously rotating crushing blade 84 breaks up any clumps in the fluid, reducing the possibility of blockage when subsequent fluid enters the drainage bag. As the crushing blade 84 rotates, it itself... A certain centrifugal force is generated, which can pull the positioning plate 85 to move to the outer side of the inner cavity of the positioning sleeve 83. At this time, the centrifugal spring 86 is stretched, causing the crusher 84 to slide out of the positioning sleeve 83 over a large area, so as to break up the scabs in the fluid over a large area. When the user finishes peritoneal dialysis, as the fluid is cut off, the transmission rod 81 will stop rotating, the crusher 84 will lose its own centrifugal force, the centrifugal spring 86 will be reset, and the positioning plate 85 will pull the crusher 84 back to the inner cavity of the positioning sleeve 83. As the side wall of the positioning sleeve 83 continuously contacts the crusher 84, the scabs adhering to the surface wall of the crusher 84 can be scraped off to ensure that the crusher 84 has sufficient sharpness.

[0038] Furthermore, the guiding mechanism 9 includes a drainage pipe 91 fixedly installed on the left side wall of the outlet pipe 4 and a guide pipe 92 fixedly installed on the right side wall of the outlet pipe 4. A sealing seat 93 is slidably installed in the inner cavity of the outlet pipe 4. A connecting rod 94 is fixedly installed on the side wall of the sealing seat 93. A handle 95 is fixedly installed at the right end of the connecting rod 94.

[0039] The connecting rod 94 is rotatably connected to the outlet pipe 4. A buffer groove 931 is provided on the side wall of the sealing seat 93. A buffer plate 96 is slidably installed in the inner cavity of the buffer groove 931. A buffer spring 97 is fixedly installed on the side wall of the buffer plate 96. The other end of the buffer spring 97 is fixedly installed on the bottom surface of the inner cavity of the buffer groove 931. Arc-shaped baffles 98 are fixedly installed on both the left and right sides of the side wall of the sealing seat 93. Through holes are provided on the side walls of the sealing seat 93 and the buffer plate 96.

[0040] It should be noted that the user can rotate the connecting rod 94 using the handle 95. Since the connecting rod 94 is rotatably connected to the outlet tube 4, the sealing seat 93 will drive the arc-shaped baffle 98 to rotate to the lower part of the side wall of the outlet tube 4, thus blocking the drainage tube 91. When the arc-shaped baffle 98 rotates to the upper part of the side wall of the outlet tube 4, it blocks the guide tube 92. Thus, as described above, this device can quickly achieve the conversion of the flow channel, greatly improving the work efficiency of medical staff. When this device is guiding the flow, the dialysate from the dialysate bag will continuously enter the outlet tube 4 from the guide tube 92. At this time, the fluid kinetic energy of the dialysate is relatively large. With the setting of the buffer spring 97, the dialysate fluid can impact the buffer plate 96, effectively reducing the impact force of the dialysate fluid entering the patient's abdomen, thereby alleviating the patient's pain.

[0041] Working principle:

[0042] During connection, the inlet tube 3 is connected to the patient's peritoneum through the dialysis tubing; the drainage tube 91 of the outlet tube 4 is connected to the waste fluid bag through the tubing, and the guide tube 92 of the outlet tube 4 is connected to the dialysis fluid bag through the tubing.

[0043] Before use, the user can use a hex wrench inserted into the internal hexagonal groove 641 to rotate the drive rod 64. At this time, the drive bevel gear 65 fixed on its side wall can drive the transmission bevel gear 63 to rotate. The transmission bevel gear 63 is slidably connected to the adjusting rod 61, and the adjusting rod 61 is threadedly connected to the adjusting sleeve 66. Under the limiting action of the second bracket 7 on the adjusting sleeve 66, the adjusting rod 61 will continuously move towards the inner cavity of the adjusting sleeve 66, so that the distance between the guide impeller 62 and the inlet pipe 3 changes. Since the guide impeller 62 is conically set at the outlet of the inlet pipe 3, the flow rate of the fluid entering the regulating cylinder 1 from the inlet pipe 3 will change, so that the whole device realizes the function of controlling the input and output flow of peritoneal dialysis, improving the practicality of the whole device.

[0044] When the entire device is used for drainage, it should be noted that the limiting strip 811 on the side wall of the transmission rod 81 and the limiting groove 821 on the rotating disk 82 do not affect the limiting effect of the transmission rod 81 on the rotating disk 82 when the position of the guide impeller 62 is adjusted. As the fluid continuously enters the inner cavity of the regulating cylinder 1 from the inlet pipe 3, when the fluid passes through the guide impeller 62, the first impeller blade 621 and the second impeller blade 622 are fixedly installed on the side wall of the guide impeller 62. At this time, the fluid can drive the guide impeller 62 to rotate the transmission rod 81 fixed in its inner cavity. The transmission rod 81 can drive the rotating disk 82 to rotate. At this time, the crushing blade 84 in the inner cavity of the positioning sleeve 83 can continuously rotate to crush the scabs in the fluid, thereby reducing the possibility of blockage when the subsequent fluid enters the drainage bag.

[0045] When the crusher blade 84 rotates, it generates a certain centrifugal force, which pulls the positioning plate 85 to move outward from the inner cavity of the positioning sleeve 83. At this time, the centrifugal spring 86 is stretched, allowing the crusher blade 84 to slide out of the positioning sleeve 83 over a large area, thus breaking up the scabs in the fluid over a wide range. When the peritoneal dialysis ends, as the fluid is cut off, the transmission rod 81 stops rotating, the crusher blade 84 loses its centrifugal force, and the centrifugal spring 86 is reset, causing the positioning plate 85 to pull the crusher blade 84 back into the inner cavity of the positioning sleeve 83. As the side wall of the positioning sleeve 83 continuously contacts the crusher blade 84, the scabs adhering to the surface of the crusher blade 84 can be scraped off, ensuring that the crusher blade 84 has sufficient sharpness.

[0046] It should be noted that when this device is diverting fluid, the fluid enters the regulating cylinder 1 from the outlet pipe 4. At this time, the fluid cannot drive the diverting impeller 62 to rotate, and the entire device can still perform the function of diverting dialysis to the patient's abdomen.

[0047] When using this device, the user can rotate the connecting rod 94 by using the handle 95. Since the connecting rod 94 is fixedly connected to the outlet pipe 4, the sealing seat 93 will drive the arc-shaped baffle 98 to rotate to the lower part of the side wall of the outlet pipe 4, thereby blocking the drainage pipe 91. When the arc-shaped baffle 98 rotates to the upper part of the side wall of the outlet pipe 4, it will block the guide pipe 92. Thus, through the above description, this device can quickly realize the conversion of the flow channel, greatly improving the work efficiency of medical staff.

[0048] During the flow of this device, the dialysate continuously flows from the dialysate bag into the outlet tube 4 through the flow tube 92. At this time, the fluid kinetic energy of the dialysate is relatively large. With the setting of the buffer spring 97, the dialysate fluid can impact the buffer plate 96, which effectively reduces the impact force of the dialysate fluid entering the patient's abdomen, thereby alleviating the patient's pain.

[0049] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
