Description

Technical Field

[0001] The present invention relates to the technical field of peritoneal dialysis, in particular to a peritoneal dialysis device with controllable flow. Background Art

[0002] Peritoneal dialysis uses the peritoneal cavity as an exchange space and the peritoneum as a semipermeable membrane to remove toxins and excess water from the body, achieving its therapeutic purpose. Due to its safety, convenience, simplicity, and rapidity, it has become an important treatment option for end-stage renal disease (ESRD). During peritoneal dialysis treatment, establishing a clear and effective peritoneal dialysis line is crucial for smooth dialysis treatment. However, complications after peritoneal dialysis catheter placement lead to approximately 20% of patients switching to hemodialysis, becoming a significant factor affecting the survival of catheter-based treatments, after peritonitis.

[0003] After searching, a peritoneal dialysis device proposed in patent publication number CN117797350A includes a dialysis tube, a tee, a peritoneal dialysis bag, a waste liquid bag and a positioning structure. The dialysis tube is connected to the peritoneal dialysis bag and the waste liquid bag through the tee. The end of the dialysis tube away from the tee is the insertion end. A plurality of dialysis holes are opened at intervals 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 document effectively addresses the problem of peritoneal dialysis catheter drift in peritoneal dialysis patients. However, certain drawbacks remain during use. For example, the inner diameter of the tee-shaped tube is uniform, making it difficult for users to control the flow of dialysate, which causes some pain for some patients. Furthermore, the internal structure of the tee-shaped tube lacks a component that can quickly switch between drainage and injection of peritoneal dialysis fluid, resulting in poor operability.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, the user can insert a hexagonal wrench into the hexagonal slot to rotate the driving rod.

The transmission bevel gear is slidably connected to the adjustment rod, and the adjustment rod is threadedly connected to the adjustment sleeve.

[0019] 3. In this invention, when using this device, the user can rotate the connecting rod through the handle.

Therefore, through the above, this device can quickly realize the conversion of the flow channel, greatly improving the work efficiency of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6The present 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, and a connecting ring 2 is slidably installed on the side walls of the adjusting cylinders 1 on both sides, a liquid inlet pipe 3 is fixedly installed on the left end face of the adjusting cylinder 1, and a liquid outlet pipe 4 is fixedly installed on the right end face of the adjusting cylinder 1, a first bracket 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 bracket 5, a second bracket 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, and a conducting mechanism 9 is provided in the inner cavity of the liquid outlet pipe 4, support frames 12 are fixedly installed on the lower parts of the side walls of the left and right adjusting cylinders 1, and positioning seats 13 are fixedly installed on the lower ends of the support frames 12 on the left and right 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 vane 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. An adjustment sleeve 66 is fixedly mounted in the inner cavity of the second bracket 7.

[0030] The guide impeller 62 is arranged at the outlet of the liquid inlet pipe 3. A first impeller blade 621 and a second impeller blade 622 are fixedly mounted on the side wall of the guide impeller 62. The first impeller blade 621 and the second impeller blade 622 are arranged in an interlaced manner. 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 arranged at an angle on the side wall of the guide impeller 62. The guide impeller 62 is arranged in a conical shape, and the liquid inlet side of the regulating cylinder 1 on the left side is designed as a conical section.

[0031] The transmission bevel gear 63 is meshed with the driving bevel gear 65, a hexagonal groove 641 is provided on the side wall of the driving rod 64, the adjusting rod 61 is threadedly connected to the adjusting sleeve 66, an annular block 21 is fixedly mounted on the inner side wall of the connecting ring 2, and an annular groove 11 is provided on the side walls of the adjusting cylinder 1 on the left and right sides, and the annular block 21 slides in the inner cavity of the annular groove 11.

[0032] The transmission bevel gear 63 is connected to the adjustment rod 61 in a manner similar to a key connection (i.e., a key is provided on the outer periphery of the adjustment rod 61, and a keyway matching the key is provided on the inner side wall of the transmission bevel gear 63, and the key is slidably connected to the keyway). In this way, the transmission bevel gear 63 can slide axially relative to the adjustment rod 61 but cannot rotate circumferentially, so as to ensure that the adjustment rod 61 is driven to rotate when the transmission bevel gear 63 rotates; in addition, the position of the transmission bevel gear 63 relative to the adjustment cylinder 1 remains unchanged (for example, a vertical rod can be connected to a ferrule at the position of the transmission bevel gear 63 on the inner side wall of the connecting ring 2, and the transmission bevel gear 63 is rotatably connected in the ferrule through a bearing), and the transmission bevel gear 63 cannot move with the movement of the adjustment rod 61. Under the limiting action of the first bracket 5 on the adjustment rod 61, the position of the transmission bevel gear 63 can be kept unchanged to ensure that the transmission bevel gear 63 can always be meshed with the driving bevel gear 65. A sealing rubber ring is provided at the connection between the connecting ring 2 and the two adjustment cylinders 1 to ensure the seal between the two adjustment cylinders 1.

[0033] It should be noted that the user can use a hexagonal wrench to insert the 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 adjustment rod 61, and the adjustment rod 61 is threadedly connected to the adjustment sleeve 66. Under the limiting effect of the second bracket 7 on the adjustment sleeve 66, the adjustment rod 61 will continue to move toward the inner cavity of the adjustment sleeve 66 to change the distance between the guide impeller 62 and the liquid inlet pipe 3. The guide impeller 62 is conically arranged at the outlet of the liquid inlet pipe 3. At this time, the flow rate of the fluid entering the adjustment cylinder 1 from the liquid inlet pipe 3 will change, so that the entire device can realize the function of controlling the input and output flow of peritoneal dialysis, thereby improving the practicality of the entire device.

[0034] Furthermore, the crushing mechanism 8 includes a transmission rod 81 fixedly mounted on the side wall of the inner cavity of the guide impeller 62, the transmission rod 81 is connected to the adjustment rod 61 and the adjustment sleeve 66, a rotating disk 82 is slidably mounted on the right side of the side wall of the transmission rod 81, a positioning sleeve 83 is fixedly mounted on the side wall of the rotating disk 82, and a crushing knife 84 is slidably mounted in the inner cavity of the positioning sleeve 83;

[0035] A positioning plate 85 is fixedly mounted on the side wall of the crushing knife 84, a centrifugal spring 86 is fixedly mounted on the side wall of the positioning plate 85, the other end of the centrifugal spring 86 is fixedly mounted on the bottom surface of the inner cavity of the positioning sleeve 83, and the rotating disk 82 is rotatably connected to the adjustment sleeve 66;

[0036] Several groups of positioning sleeves 83 and crushing knives 84 are arranged in an annular manner at equal intervals on the side wall of the rotating disk 82. A limiting groove 821 is opened on the inner side wall of the rotating disk 82. A limiting strip 811 is slidably installed in the inner cavity of the limiting groove 821, and the limiting strip 811 is fixedly installed on the side wall of the transmission rod 81.

[0037] It should be noted that when the entire device is used for drainage, as the fluid continuously enters the inner cavity of the regulating cylinder 1 from the liquid 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 to its inner cavity, and the transmission rod 81 can drive the rotating disk 82 to rotate. At this time, the inner cavity crushing knife 84 of the positioning sleeve 83 is set. The crushing knife 84 rotates continuously to crush the scab in the fluid, so as to reduce the possibility of blockage when the subsequent fluid enters the drainage bag. When the crushing knife 84 rotates, the crushing knife 84 itself will A certain centrifugal force is generated, which can pull the positioning plate 85 toward the outside of the inner cavity of the positioning sleeve 83. At this time, the centrifugal spring 86 is stretched, causing the crushing knife 84 to slide out of the positioning sleeve 83 over a larger area, so as to achieve large-scale crushing of scabs in the fluid. When the user finishes peritoneal dialysis, as the fluid is cut off, the transmission rod 81 will stop rotating, the crushing knife 84 will lose its own centrifugal force, and the centrifugal spring 86 will be reset, causing the positioning plate 85 to pull the crushing knife 84 toward the inner cavity of the positioning sleeve 83 again. As the side wall of the positioning sleeve 83 continues to contact the crushing knife 84, the scabs adhering to the surface wall of the crushing knife 84 can be scraped off to ensure that the crushing knife 84 has sufficient sharpness.

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

[0039] The connecting rod 94 is rotatably connected to the liquid outlet pipe 4, and 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, and 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 the left and right sides of the side wall of the sealing seat 93, and 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 through the handle 95. Since the connecting rod 94 is rotatably connected to the liquid outlet pipe 4, the blocking seat 93 will drive the arc baffle 98 to rotate to the lower part of the side wall of the liquid outlet pipe 4, thereby blocking the drainage tube 91. When the arc baffle 98 rotates to the upper part of the side wall of the liquid outlet pipe 4, the diversion tube 92 is blocked. Therefore, through the above, the device can quickly realize the conversion of the flow channel, greatly improving the work efficiency of medical staff. When the device is diverting, the dialysate in the dialysate bag will continuously enter the liquid outlet pipe 4 from the diversion tube 92. At this time, the fluid kinetic energy of the dialysate is large, and through 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] When connected, the inlet tube 3 is connected to the patient's peritoneum through the dialysis line; the drainage tube 91 of the outlet tube 4 is connected to the waste liquid bag through the line, and the guide tube 92 of the outlet tube 4 is connected to the dialysate bag through the line;

[0043] Before using the device, the user can insert a hexagonal wrench into the hexagonal slot 641 to rotate the driving rod 64. At this time, the driving bevel gear 65 fixed on the side wall can drive the transmission bevel gear 63 to rotate. The transmission bevel gear 63 is slidably connected to the adjustment rod 61, and the adjustment rod 61 is threadedly connected to the adjustment sleeve 66. Under the limiting effect of the second bracket 7 on the adjustment sleeve 66, the adjustment rod 61 will continue to move toward the inner cavity of the adjustment sleeve 66 to change the distance between the guide impeller 62 and the liquid inlet pipe 3. The guide impeller 62 is conically arranged at the outlet of the liquid inlet pipe 3. At this time, the flow rate of the fluid entering the regulating cylinder 1 from the liquid inlet pipe 3 will change, so that the entire device can realize the function of controlling the input and output flow rates of peritoneal dialysis, thereby improving the practicality of the entire device.

[0044] When the entire device is used for drainage, it should be noted that, through the setting of the limiting strip 811 on the side wall of the transmission rod 81 and the limiting groove 821 on the rotating disk 82, when the position of the guide impeller 62 is adjusted, it does not affect the limiting effect of the transmission rod 81 on the rotating disk 82. As the fluid continuously enters the inner cavity of the regulating cylinder 1 from the liquid 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 to its inner cavity, and the rotating disk 82 can be driven to rotate through the transmission rod 81. At this time, through the setting of the inner cavity crushing knife 84 of the positioning sleeve 83, the crushing knife 84 continuously rotates to crush the scab in the fluid, so as to reduce the possibility of blockage when the subsequent fluid enters the drainage bag;

[0045] When the crushing knife 84 rotates, the crushing knife 84 itself will generate a certain centrifugal force, which can pull the positioning plate 85 to move toward the outside of the inner cavity of the positioning sleeve 83. At this time, the centrifugal spring 86 is stretched, causing the crushing knife 84 to slide out of the positioning sleeve 83 over a large area, so as to achieve large-scale crushing of scabs in the fluid. When the user finishes peritoneal dialysis, as the fluid is cut off, the transmission rod 81 will stop rotating, the crushing knife 84 will lose its own centrifugal force, and the centrifugal spring 86 will be reset, causing the positioning plate 85 to pull the crushing knife 84 toward the inner cavity of the positioning sleeve 83 again. As the side wall of the positioning sleeve 83 continues to contact the crushing knife 84, the scabs adhering to the surface wall of the crushing knife 84 can be scraped off, thereby ensuring that the crushing knife 84 has sufficient sharpness.

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

[0047] When the device is in use, the user can rotate the connecting rod 94 through the handle 95. Since the connecting rod 94 is fixedly connected to the liquid outlet pipe 4, the blocking seat 93 will drive the arc-shaped baffle 98 to rotate to the lower part of the side wall of the liquid 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 liquid outlet pipe 4, the drainage pipe 92 is blocked. As described above, the device can quickly realize the conversion of the flow channel, greatly improving the work efficiency of medical staff.

[0048] When the device is diverting, the dialysate in the dialysate bag will continuously enter the liquid outlet pipe 4 from the diversion tube 92. At this time, the fluid kinetic energy of the dialysate is relatively large, and through 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.

[0049] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
