Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an anti-blocking device and an anti-blocking method for chronic kidney disease dialysis equipment. Background Art

[0002] Chronic kidney disease refers to chronic kidney structural and functional disorders caused by various reasons, including normal and abnormal pathological damage to the glomerular filtration rate (GFR), abnormal blood or urine components, abnormal imaging examinations, or unexplained decrease in GFR. These conditions often lead to the kidneys being unable to effectively eliminate waste and excess water from the body, thus requiring dialysis treatment. Dialysis is a separation and purification technology that separates small molecules from biomacromolecules by diffusing small molecules through a semipermeable membrane into water or a buffer solution. It is widely used in the treatment of chronic kidney disease.

[0003] At present, the anti-blocking methods of dialysis equipment are mainly divided into two types: peritoneal dialysis and hemodialysis. Peritoneal dialysis is a method of placing a dialysis tube in the abdominal cavity and using the peritoneum as a dialysis membrane to discharge waste and excess water from the body. However, during peritoneal dialysis, the placement tube and the drainage catheter are often blocked by protein clots. Specifically, when the dialysate enters the abdominal cavity through the placement tube, exchanges with the effusion in the abdominal cavity, and is then discharged from the body through the drainage tube, if the effusion contains more protein or other impurities, it is easy to form clots in the pipe, causing the pipe to be blocked. This blockage will not only affect the flow of the dialysate, but also affect the discharge of the effusion, thereby endangering the patient's treatment effect and life safety.

[0004] In the prior art, for the problem of peritoneal dialysis tube blockage, sensors are usually used to sense the blockage and notify medical staff to handle it. However, this method cannot automatically solve the blockage problem, and medical staff still need to manually operate the delivery of defibrin to dissolve protein clots, which not only increases the workload of medical staff, but may also lead to serious consequences due to untimely treatment. Therefore, in view of the problem that the sensor is only used to sense the situation in the peritoneal dialysis tube and cannot automatically handle the protein clot blockage while sensing, an anti-blocking device and an anti-blocking method are proposed that can automatically and efficiently solve the problem of peritoneal dialysis tube blockage. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an anti-blocking device and an anti-blocking method for chronic kidney disease dialysis equipment, which senses the blockage situation in the catheter through the rotation speed of the turbine assembly and automatically delivers defibrase for digesting protein clots when the catheter is blocked, thereby achieving the purpose of automatically handling catheter blockage.

[0006] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: an anti-blocking device for chronic kidney disease dialysis equipment, comprising a dialysis bag, a placement tube and a drainage bag, a first catheter being connected between the dialysis bag and the placement tube, a second catheter being connected between the drainage bag and the placement tube, a valve being connected at the connection between the first catheter and the second catheter and the placement tube, and a controller being connected to the valve signal;

[0007] The placement tube and the second catheter are both connected with an anti-blocking component to prevent the pipeline from being blocked. The anti-blocking components include a circulation cavity and a driving box. The driving box is provided with a driving cavity. The connection between the placement tube and the second catheter and the driving box is fixedly connected. A driven component is rotatably connected in the driving cavity. The other end of the driven component extends to the circulation cavity. The driven component is located on one side of the circulation cavity and is provided with an expansion component for expanding the diameter of the placement tube or the second catheter. The driven component is located on one side of the driving cavity and is fixedly connected with a conveying component. The conveying component is used to autonomously convey an enzyme for digesting protein clots to the circulation cavity according to changes in the blood flow rate in the circulation cavity.

[0008] A turbine assembly for driving the driven assembly to move is sleeved on the driven assembly. The turbine assembly is located in the circulation chamber, and a transmission gear is arranged between the driven assembly and the turbine assembly. One side of the transmission gear is rotatably connected to the inner wall of the driving box. A spring driven by the driven assembly and the turbine assembly is arranged between the turbine assembly and the driven assembly.

[0009] The technical principle of the above scheme is as follows: the dialysis bag is used to hold the patient's blood and remove waste and excess water therefrom through the dialysis process; the drainage bag is used to collect and store blood or waste fluid after dialysis treatment; the placement tube is used to connect the dialysis bag and the drainage bag to the first catheter and the second catheter to ensure that the blood and dialysate can flow smoothly; the valve is controlled by the controller signal to adjust the connection state between the first catheter and the second catheter and the placement tube, thereby controlling the flow direction of the blood or dialysate.

[0010] When the accumulated fluid in the abdominal cavity is discharged into the drainage bag, the power generated by the flow of the accumulated fluid will drive the turbine assembly to rotate and generate lift. The turbine assembly is lifted by the rotational force and separated from the transmission gear. At this time, the driven assembly does not move. When there is a risk of pipeline blockage during dialysis, the flow rate in the placement tube or the second catheter slows down, the turbine assembly stops rising, and the spring resets the turbine assembly. However, since there is still accumulated fluid flowing in the placement tube or the second guide rod, the turbine assembly will still rotate under the flushing of the accumulated fluid. At this time, the turbine assembly is meshed with the transmission gear and drives the driven assembly to rotate. The rotation of the driven assembly will drive the expansion assembly to expand the diameter of the placement tube or the second catheter, thereby increasing the diameter of the tube through which the accumulated fluid can flow, and will not immediately cause blockage of the placement tube or the second catheter. At the same time, the delivery assembly delivers enzymes that digest protein clots to the circulation cavity. These enzymes will decompose the protein clots that cause blockage of the placement tube or the second catheter, thereby restoring the normal flow of the accumulated fluid. The turbine assembly continues to separate from the transmission gear under the flushing of the accumulated fluid at normal flow rate, preparing for the next dredging.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This solution can monitor the flow rate changes in the catheter in real time through the speed sensing function of the turbine assembly, thereby indirectly judging whether there is a risk of blockage. Once the flow rate slows down, it means there may be a blockage. At this time, the device will automatically start the anti-blockage mechanism and eliminate the blockage by delivering enzymes that digest protein clots without manual intervention, greatly improving the timeliness and efficiency of the treatment.

[0013] 2. In this solution, the controller and valve system in the device can intelligently adjust the flow direction and speed of blood according to the actual needs of the dialysis process, thereby preventing the occurrence of blockage to a certain extent. At the same time, the design of the expansion component can also ensure that when blockage occurs, the effective diameter of the pipeline is maintained to the maximum extent, delaying the blockage process.

[0014] 3. This solution uses anti-blocking components to automatically handle blockages and intelligently regulate blood flow. The device can significantly improve the safety and stability of the dialysis process, and promptly handle blockages when the placement tube and the second catheter are about to become blocked, thereby reducing the response time from sensor response to notifying medical staff, and reducing the risk of dialysis interruption and patient discomfort caused by untimely handling of pipeline blockage.

[0015] 4. In this solution, since the driven component can accurately respond to the rotation of the turbine component and promptly activate the anti-blocking mechanism when needed, the anti-blocking efficiency and reliability are greatly improved, which reduces the number of dialysis interruptions caused by pipeline blockage, extends the continuous use time of the dialysis equipment, and improves the treatment efficiency.

[0016] Furthermore, the turbine assembly includes a driving face gear and a plurality of turbine blades. A hollow first fixed rod is coaxially connected to the top of the driving face gear. The first fixed rod is slidably matched with the top wall of the drive box and extends into the flow chamber. A first fixed ring is fixedly connected to the top of the first fixed rod. The turbine blades are evenly distributed on the first fixed ring in the circumference. When the turbine blades are driven, a force is applied to the first fixed rod to move away from the driven assembly.

[0017] Beneficial effects: As a key component of fluid power conversion, the turbine blades can efficiently capture the kinetic energy of the fluid when the effluent flows, and convert it into the rotational kinetic energy of the turbine assembly. The turbine blades can maintain stable rotation at different flow rates, thereby accurately reflecting the flow rate changes in the conduit. When the effluent flows normally, the flow rate is fast, the turbine blades speed up and can drive the active face gear to separate from the transmission gear. When the effluent is blocked, the flow rate slows down, the turbine blades keep rotating but the speed slows down, and the active face gear is meshed with the transmission gear through spring reset and drives the transmission gear to rotate; the fixed connection between the active face gear and the turbine blades ensures the consistency of the speed. When the turbine blades rotate due to the scouring of the fluid, the active face gear will also rotate. This direct transmission method reduces energy loss and improves the accuracy and stability of speed sensing.

[0018] Furthermore, the driven assembly includes a second fixed rod and a driven face gear fixedly connected to the second fixed rod, the second fixed rod is rotatably connected to the bottom of the driving box, the first fixed rod is sleeved on the second fixed rod, the second fixed rod extends into the flow cavity and extends outside the first fixed rod, and one end of the second fixed rod extending outside the first fixed rod is fixedly connected to a plurality of second fixed rings, and the springs are fixedly connected between the first fixed ring and the second fixed ring, and when the turbine blades are not driven, the active face gear and the driven face gear are respectively in meshing state with both sides of the transmission gear.

[0019] Beneficial effects: The driving face gear and the driven face gear are respectively meshed with the two sides of the transmission gear, ensuring a stable transmission relationship between the turbine assembly and the driven assembly. This design enables the driven assembly to be accurately driven to rotate through the transmission gear when the turbine assembly is rotated by the fluid flushing, thereby realizing accurate transmission of the rotation speed; the spring is fixedly connected between the first fixed ring and the second fixed ring, providing a flexible reset mechanism for the relative movement between the turbine assembly and the driven assembly. When the flow rate of the accumulated liquid slows down, the turbine assembly stops rising and separates from the transmission gear, the spring can quickly reset the turbine assembly to ensure that it can re-engage with the transmission gear when the accumulated liquid is flushed again. This design improves the response speed and accuracy of the device to changes in flow rate.

[0020] Furthermore, a limit block for limiting the lifting height of the turbine blade is coaxially fixedly connected to one end of the second fixing rod close to the turbine blade.

[0021] Beneficial effect: The design of the limit block can prevent the turbine blades from being lifted too high due to excessive force during rotation, thereby avoiding collision between the blades and the second fixing ring and protecting the integrity of the turbine blades.

[0022] Furthermore, one end of the second fixed rod located in the circulation chamber is coaxially fixedly connected to the first screw rod, and the expansion assembly includes a first nut seat and an arc plate fixedly connected to the first screw rod, and a plurality of guide rods are fixedly connected between the first nut seat and the arc plate, and the side wall in the circulation chamber is located in the movement trajectory of the arc plate.

[0023] Beneficial effect: By rotating the first screw, the first nut seat can be driven to move along the screw axis. Since the first nut seat and the arc plate are fixedly connected by the guide rod, the arc plate will be expanded as the first nut seat moves. When the expansion assembly is in the expanded state, it can ensure that the accumulated liquid in the flow cavity can pass smoothly.

[0024] Furthermore, the side walls of the placement tube and the second catheter are both elastic.

[0025] Beneficial effect: The elastic side walls can open the side walls of the placement tube and the second catheter when they are blocked, thus preventing the blockage from directly causing internal blockage of the placement tube and the second catheter. The elastic setting of the side walls enables the arc plate to obtain a buffering force when squeezing the side walls of the flow chamber, and the side walls of the flow chamber will not be squeezed and cracked by the arc plate.

[0026] Furthermore, the conveying component includes a liquid box for storing enzymes for digesting protein clots and a driving bevel gear coaxially fixedly connected to the second fixed rod, a bevel gear is meshed on one side of the driving bevel gear, and a second screw is coaxially fixedly connected to the axis of the bevel gear, one end of the second screw passes through the bevel gear and is rotatably connected to a support rod, the support rod is fixedly connected to the bottom wall of the driving chamber, the second screw is threadedly connected to a second nut seat, the second nut seat is fixedly connected to a piston, the second screw passes through the piston and is slidably connected to the piston, the outer wall of the piston is slidably connected to the inner wall of the liquid box, a conveying pipe is connected to the side of the liquid box away from the second screw, a one-way valve that only flows from the liquid box into the circulation chamber is provided at the connection between the conveying pipe and the liquid box, and an end of the conveying pipe away from the liquid box is connected to the circulation chamber.

[0027] Beneficial effect: When the piston moves in the liquid box, it pushes the enzyme that digests the protein clot to flow along the liquid box toward the delivery tube. Since a one-way valve is provided at the connection between the delivery tube and the liquid box, it ensures that the enzyme that digests the protein clot can only flow from the liquid box into the flow cavity, and also avoids the reflux of the accumulated liquid into the liquid box, thereby improving the enzyme delivery efficiency.

[0028] Furthermore, an ultrasonic sensor is fixedly connected to the outer wall of the valve, and the ultrasonic sensor signal is connected to a controller. The controller is used to obtain the patient's abdominal height and the drainage bag height in real time, define the patient's abdominal height position when the height difference is obtained, and calculate the height difference between the two in the controller based on the height of the drainage bag.

[0029] Beneficial effects: Through the signal connection between the ultrasonic sensor and the controller, the controller can automatically detect and respond to changes in the height difference between the patient's abdomen and the drainage bag. This automated adjustment mechanism reduces the manual intervention of medical staff and improves work efficiency. The ultrasonic sensor monitors and automatically adjusts the distance between the patient's abdomen and the drainage bag in real time, which helps to keep the drainage tube unobstructed and prevent blockage of the drainage bag due to too close a distance or improper angle.

[0030] Furthermore, a support frame is provided on one side of the dialysis bag, and a first jacket for clamping the dialysis bag is fixedly connected to the upper part of the support frame, and a placement seat for placing the valve is also fixedly connected to the support frame, and a second jacket for clamping the drainage bag is slidably connected to the lower part of the support frame, and an electric telescopic rod is fixedly connected between the second jacket and the placement seat, and the output shaft of the electric telescopic rod is fixedly connected to the second jacket, and the electric telescopic rod is connected to the controller signal, and the controller is used to control the operation of the electric telescopic rod according to a preset height difference between the patient's abdomen and the drainage bag, so that the electric telescopic rod pushes the second jacket to adjust the distance between the drainage bag and the patient's abdomen. When the height difference acquired by the ultrasonic sensor is greater than or equal to the drop threshold, the electric telescopic rod stops running.

[0031] Beneficial effects: Under the monitoring of the ultrasonic sensor, when the height difference between the patient's abdomen and the drainage bag is less than the threshold set by the controller, the controller adjusts the distance between the drainage bag on the second jacket and the patient's abdomen through the pneumatic electric telescopic rod, ensuring that the drainage bag is always in the best drainage position, thereby optimizing the drainage effect and reducing the risk of poor drainage or blockage.

[0032] A method for preventing blocking of a chronic kidney disease dialysis device comprises the following steps:

[0033] Step 1, preparation: place the dialysis bag and the drainage bag in the first jacket and the second jacket respectively, so as to connect the dialysis bag, the first catheter, the valve, the placement tube, the second catheter and the drainage bag, and the placement tube and the second catheter are both connected to the anti-blocking component;

[0034] Step 2, dialysis process: fix the greater omentum to the patient's high parietal peritoneum using laparoscopic omentopexy, fix the placement tube to the greater omentum using sutures, the placement tube, the placement seat and the valve are all on the same horizontal line with the patient's abdomen, and the controller opens the valve to allow the dialysate to enter the patient's abdominal cavity from the dialysis bag through the first catheter to perform peritoneal dialysis;

[0035] Step 3, anti-blocking process: When the accumulated fluid in the patient's abdominal cavity needs to be discharged, the valve closes the passage between the first catheter and the placement tube and opens the passage between the placement tube and the second catheter. The accumulated fluid flushes the turbine assembly when flowing to the drainage bag, causing the turbine assembly to rotate rapidly and separate from the transmission gear through the lifting force of the turbine assembly. At this time, the driven assembly does not rotate, and the spring between the turbine assembly and the driven assembly is compressed. At this time, the accumulated fluid flows normally; when the accumulated fluid is blocked by protein clots in the placement tube or the second catheter, the flow rate of the accumulated fluid slows down, the speed of the turbine assembly slows down, and the lifting stops , the spring resets the turbine assembly, at which time the turbine assembly, the transmission gear and the driven assembly are meshed, the turbine assembly continues to rotate, driving the driven assembly to rotate, thereby causing the expansion assembly coaxially fixedly connected to the driven face gear to move toward the side wall of the flow cavity and expand the side wall of the flow cavity, thereby increasing the flow path of the effusion in the placement tube or the second catheter; at the same time, the driven assembly also drives the conveying assembly to reciprocate, and the defibrase or viper antithrombotic enzyme in the conveying assembly enters the flow cavity under its extrusion and mixes with the effusion, dissolving the protein clot, so that the effusion gradually resumes normal flow;

[0036] Step 4: External anti-blockage: The patient needs to constantly change his position or the medical staff needs to massage the patient's abdomen to alleviate the blockage of the tube. When the patient changes his position, the ultrasonic sensor can detect the height difference between the patient's abdomen and the drainage bag. When the height difference between the patient's abdomen and the drainage bag is less than 30cm, the controller starts the electric telescopic rod to make the second jacket slide downward along the support frame to adjust the distance between the patient's abdomen and the drainage bag.

[0037] Beneficial effects:

[0038] 1. This method ensures the smooth flow of dialysate in the patient's abdominal cavity through a sophisticated anti-blocking design, avoiding the decrease in dialysis efficiency or patient discomfort caused by fluid blockage. At the same time, the safety and stability of the dialysis process are further guaranteed by real-time monitoring and adjustment of the distance between the patient's abdomen and the drainage bag.

[0039] 2. The introduction of automated components such as turbine components, transmission gears, driven components and expansion components enables real-time monitoring and adaptive adjustment of the flow rate of the effluent. When the flow rate of the effluent slows down, the turbine component can automatically reset and mesh with the transmission gear, thereby driving the expansion component to expand the side wall of the flow cavity and increase the flow path. This automated anti-blocking mechanism not only improves the anti-blocking efficiency, but also reduces the frequency and difficulty of manual intervention.

[0040] 3. By constantly changing the body position or having medical staff massage the patient's abdomen, combined with real-time monitoring by the ultrasonic sensor and automatic adjustment of the electric telescopic rod, the blockage of the placement tube can be effectively alleviated, reducing the discomfort and risk of complications caused by long-term fixed body position or poor drainage.

[0041] 4. The defibrase or viper antithrombotic enzyme in the delivery component enters the circulation cavity and mixes with the effusion under the extrusion of reciprocating motion, which can quickly dissolve protein clots and restore the normal flow of the effusion. This way of using drugs not only improves the utilization rate and effect of drugs, but also avoids the side effects caused by overdose or improper use of drugs.

[0042] 5. The automated anti-blocking design reduces the frequency of manual intervention and monitoring by medical staff, and reduces their workload and labor intensity. At the same time, it also improves the accuracy and efficiency of medical care, providing patients with safer, more comfortable and efficient dialysis services.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The following is further described in detail through specific implementation methods:

[0053] Embodiment 1:

[0054] As attached Figure 1 , Figure 2 and Figure 3 As shown: an anti-blocking device for chronic kidney disease dialysis equipment, including a dialysis bag 4, a placement tube 1 and a drainage bag 12, a first catheter 5 is connected between the dialysis bag 4 and the placement tube 1, a second catheter 10 is connected between the drainage bag 12 and the placement tube 1, and a valve 6 is connected at the connection point between the first catheter 5 and the second catheter 10 and the placement tube 1.

[0055] The side walls of the placement tube 1 and the second conduit 10 are both elastic, and the placement tube 1 and the second conduit 10 are both connected with an anti-blocking component for preventing the pipeline from being blocked. The anti-blocking component includes a circulation cavity 13 and a drive box 8. The drive box 8 is provided with a drive cavity 19. The connection between the placement tube 1 and the second conduit 10 and the drive box 8 is bonded and fixed. A driven component is rotatably connected in the drive cavity 19. The other end of the driven component extends to the circulation cavity 13. The driven component is located on one side of the circulation cavity 13 and is provided with a device for opening the placement tube 1 or the second conduit 1. The expansion component has a diameter of 0, and the driven component is located on one side of the driving cavity 19 and is provided with a conveying component. The conveying component is used to autonomously convey an enzyme (usually nafamosin mesylate) for dissolving protein clots to the circulation cavity 13 according to the change of blood flow rate in the circulation cavity 13. Specifically, when the blood flow rate in the circulation cavity 13 is normal (no blockage occurs), the enzyme for dissolving protein clots is not conveyed to the circulation cavity 13. When the blood flow rate in the circulation cavity 13 is too low (blockage occurs), the enzyme for dissolving protein clots is conveyed to the circulation cavity 13.

[0056] The driven component is sleeved with a turbine component for driving the driven component to move. The turbine component is located in the circulation chamber 13. A transmission gear 21 is arranged between the driven component and the turbine component. The transmission gear 21 is rotatably connected to the inner wall of the driving box 8. A spring 15 is arranged between the turbine component and the driven component so that the driven component and the turbine component are driven by the transmission gear 21. Specifically, when the blood flow rate in the circulation chamber 13 is normal (no blockage occurs), the turbine component rotates faster, generating a lift force to resist the elastic force of the spring 15, so that the transmission between the driven component and the turbine component disappears, and the turbine component rotates alone; when the blood flow rate in the circulation chamber 13 is too low (blockage occurs), the turbine component rotates slower, generating a lift force that cannot resist the elastic force of the spring 15, so that the transmission between the driven component and the turbine component occurs, and the turbine component drives the driven component to operate.

[0057] The turbine assembly includes a driving face gear 31 and a plurality of turbine blades 16. The driving face gear 31 is coaxially bonded with a hollow first fixing rod 18. The first fixing rod 18 is slidably matched with the top wall of the driving box 8 and extends into the flow chamber 13. A first fixing ring 17 is welded to the top of the first fixing rod 18. The turbine blades 16 are evenly distributed on the first fixing ring 17 in the circumferential direction. When the turbine blades 16 are driven, a force is applied to the first fixing rod 18 to move away from the driven assembly, that is, a force to lift the first fixing rod 18.

[0058] The driven assembly includes a second fixed rod 30 and a driven face gear 29 welded to the second fixed rod 30, the second fixed rod 30 is rotatably connected to the bottom of the drive box 8, the first fixed rod 18 is sleeved on the second fixed rod 30, the second fixed rod 30 extends into the circulation cavity 13, and extends to the outside of the first fixed rod 18, the end of the second fixed rod 30 extending outside the first fixed rod 18 is welded with a second fixed ring 14, the spring 15 is welded between the first fixed ring 17 and the second fixed ring 14, when the turbine blade 16 is not driven (not in use), the active face gear 31 and the driven face gear 29 are respectively kept in full meshing state with both sides of the transmission gear 21, and the end of the second fixed rod 30 close to the turbine blade 16 is coaxially bonded and fixed with a limit block for limiting the lifting height of the turbine blade 16.

[0059] The second fixed rod 30 is coaxially bonded and fixed with the first screw rod 32 at one end located in the circulation chamber 13. The expansion components include a first nut seat 33 and an arc plate 35 threadedly connected to the first screw rod 32. A plurality of guide rods 34 are welded between the first nut seat 33 and the arc plate 35. The side wall in the circulation chamber 13 is located in the movement trajectory of the arc plate 35.

[0060] The conveying assembly includes a liquid box 22 for storing enzymes for digesting protein clots and a driving bevel gear 26 coaxially keyed to a second fixed rod 30, a bevel gear 27 meshing on one side of the driving bevel gear 26, a second screw rod 25 coaxially welded to the axis of the bevel gear 27, one end of the second screw rod 25 passes through the bevel gear 27 and is rotatably connected to a support rod 28, the support rod 28 is welded to the inner bottom wall of the driving chamber 19, a second nut seat 23 is threadedly connected to the second screw rod 25, a piston 24 is welded to the second nut seat 23, the second screw rod 25 passes through the piston 24 and is slidably connected to the piston 24, the outer wall of the piston 24 is slidably connected to the inner wall of the liquid box 22, a conveying pipe 20 is connected to the side of the liquid box 22 away from the second screw rod 25, a one-way valve that only flows from the liquid box 22 into the circulation chamber 13 is provided at the connection between the conveying pipe 20 and the liquid box 22, and the end of the conveying pipe 20 away from the liquid box 22 is communicated with the circulation chamber 13.

[0061] The specific implementation process is as follows: the dialysis bag 4 and the drainage bag 12 are placed in the first jacket 3 and the second jacket 11 respectively, so as to connect the dialysis bag 4, the first catheter 5, the valve 6, the placement tube 1, the second catheter 10 and the drainage bag 12. The placement tube 1 and the second catheter 10 are both connected to the drive box 8. When the fluid in the patient's abdominal cavity needs to be discharged, the valve 6 closes the passage between the first catheter 5 and the placement tube 1 and opens the passage between the placement tube 1 and the second catheter 10. When the accumulated fluid flows to the drainage bag 12, the turbine blades 16 in the circulation cavity 13 are flushed, and the flow rate of the accumulated fluid is converted into the rotational kinetic energy of the turbine blades 16, so that the turbine blades 16 rotate rapidly. The turbine blades 16 drive the active face gear 31 to be lifted and separated from the transmission gear 21 through the first fixed rod 18. The design of the limit block can prevent the turbine blades 16 from being lifted too high due to excessive force during rotation, thereby avoiding the collision between the blades and the second fixed ring 14. The spring 15 between the first fixed ring 17 and the second fixed ring 14 is compressed, and the accumulated fluid flows normally at this time.

[0062] When protein clots block the effusion in the placement tube 1 or the second catheter 10, the flow rate of the effusion slows down, the rotation speed of the turbine blade 16 slows down, the active face gear 31 stops lifting, the spring 15 resets, and the first fixed rod 18 resets. At this time, the active face gear 31 is meshed with the transmission gear 21, and the turbine blade 16 continues to rotate, driving the active face gear 31 to rotate, and the driven face gear 29 is driven to rotate through the transmission gear 21, thereby causing the second fixed rod 30 coaxially fixedly connected to the driven face gear 29 to rotate, driving the first screw rod 32 on the second fixed rod 30 to rotate, and the first nut seat 33 slides on the first screw rod 32 ... The arc plate 35 moves toward the side wall of the circulation chamber 13 and opens the side wall of the circulation chamber 13, thereby increasing the flow path of the accumulated fluid in the placement tube 1 or the second catheter 10; at the same time, the bevel gear 26 is driven to rotate with the second fixed rod 30, and the bevel gear 27 is driven to rotate, so that the second screw rod 25 rotates. At this time, the second nut seat 23 slides on the second screw rod 25, and drives the piston 24 to move toward the end of the delivery tube 20 in the liquid box 22, squeezing the defibrillase in the liquid box 22 to flow toward the delivery tube 20, thereby allowing the defibrillase or viper antithrombotic enzyme to enter the circulation chamber 13 and mix with the accumulated fluid, dissolve protein clots, and gradually restore the normal flow of the accumulated fluid.

[0063] Embodiment 2:

[0064] As attached Figure 2 As shown, the difference from Example 1 is that an ultrasonic sensor is screwed onto the outer wall of the valve 6, and the ultrasonic sensor signal is connected to a controller. The ultrasonic sensor signal is connected to a controller, and the controller is used to obtain the patient's abdominal height and the height of the drainage bag 12 in real time, define the patient's abdominal height position when obtaining the height difference, and calculate the height difference between the two based on the height of the drainage bag 12 in the controller.

[0065] A support frame 2 is provided on one side of the dialysis bag 4, and a first jacket 3 for clamping the dialysis bag 4 is welded on the upper part of the support frame 2, and a placement seat 7 for placing the valve 6 is also welded on the support frame 2. A second jacket 11 for clamping the drainage bag 12 is slidably connected to the lower part of the support frame 2, and an electric telescopic rod 9 is bolted between the second jacket 11 and the placement seat 7, and the output shaft of the electric telescopic rod 9 is bolted to the second jacket 11. The electric telescopic rod 9 is connected to the controller signal, and the controller is used to control the operation of the electric telescopic rod 9 according to the preset height difference between the patient's abdomen and the drainage bag 12, so that the electric telescopic rod 9 pushes the second jacket 11 to adjust the distance between the drainage bag 12 and the patient's abdomen. When the height difference collected by the ultrasonic sensor is greater than or equal to the drop threshold, the electric telescopic rod 9 stops running.

[0066] The specific implementation process is as follows: through the signal connection between the ultrasonic sensor and the controller, the controller can automatically detect and respond to the change in the height difference between the patient's abdomen and the drainage bag 12, and the ultrasonic sensor monitors and automatically adjusts the distance between the patient's abdomen and the drainage bag 12 in real time. Under the monitoring of the ultrasonic sensor, when the height difference between the patient's abdomen and the drainage bag 12 is less than the threshold set by the controller, the controller adjusts the distance between the drainage bag 12 on the second jacket 11 and the patient's abdomen through the pneumatic electric telescopic rod 9, ensuring that the drainage bag 12 is always in the best drainage position, helping to keep the drainage tube unobstructed, preventing the placement tube 1 and the second catheter 10 from bending and causing blockage due to being too close or at an improper angle, and allowing the patient's abdominal fluid to always flow into the drainage bag 12 by gravity.

[0067] Embodiment 3:

[0068] As attached Figure 4 As shown, the difference from Example 2 is that a method for preventing blocking of a chronic kidney disease dialysis device comprises the following steps:

[0069] Step 1, preparation: place the dialysis bag 4 and the drainage bag 12 in the first jacket 3 and the second jacket 11 respectively, so as to connect the dialysis bag 4, the first catheter 5, the valve 6, the placement tube 1, the second catheter 10 and the drainage bag 12, and the placement tube 1 and the second catheter 10 are both connected to the anti-blocking component;

[0070] Step 2, dialysis process: fix the greater omentum to the high parietal peritoneum of the patient by laparoscopic omentopexy, fix the placement tube 1 to the greater omentum by sutures, the placement tube 1, the placement seat 7 and the valve 6 are all on the same horizontal line with the patient's abdomen, and the controller opens the valve 6 to allow the dialysate to enter the patient's abdominal cavity from the dialysis bag 4 through the first catheter 5 to perform peritoneal dialysis;

[0071] Step three, anti-blocking process: when the patient's abdominal fluid needs to be discharged, the valve 6 closes the passage between the first catheter 5 and the placement tube 1 and opens the passage between the placement tube 1 and the second catheter 10. The accumulated fluid flushes the turbine assembly when flowing to the drainage bag 12, causing the turbine assembly to rotate rapidly and separate from the transmission gear 21 through the lifting force of the turbine assembly. At this time, the driven assembly does not rotate, and the spring 15 between the turbine assembly and the driven assembly is compressed. At this time, the accumulated fluid flows normally; when the accumulated fluid is blocked by protein clots in the placement tube 1 or the second catheter 10, the flow rate of the accumulated fluid slows down, the rotation speed of the turbine assembly slows down, and the lifting stops , the spring 15 resets the turbine assembly, at which time the turbine assembly, the transmission gear 21 and the driven assembly are meshed, the turbine assembly continues to rotate, driving the driven assembly to rotate, and then the expansion assembly coaxially fixedly connected to the driven face gear 29 moves toward the side wall of the circulation cavity 13 and expands the side wall of the circulation cavity 13, so that the flow path of the effusion in the placement tube 1 or the second catheter 10 is increased; at the same time, the driven assembly also drives the conveying assembly to reciprocate, and the defibrase or viper antithrombotic enzyme in the conveying assembly enters the circulation cavity 13 under its extrusion and mixes with the effusion, dissolves the protein clot, and gradually restores the effusion to normal flow;

[0072] Step 4, external anti-blocking: the patient needs to constantly change his position or the medical staff needs to massage the patient's abdomen to alleviate the blockage of the placement tube 1. When the patient changes his position, the ultrasonic sensor can detect the height difference between the patient's abdomen and the drainage bag 12. When the height difference between the patient's abdomen and the drainage bag 12 is less than 30 cm, the controller starts the electric telescopic rod 9 to make the second jacket 11 slide downward along the support frame 2 to adjust the distance between the patient's abdomen and the drainage bag 12.

[0073] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
