Description

Technical Field

[0001] The invention belongs to the technical field of peritoneal dialysis fluid exchange, and in particular relates to a peritoneal dialysis fluid exchange device and a use method thereof. Background Art

[0002] Peritoneal dialysis is an important alternative treatment for end-stage renal disease. Its core lies in achieving solute exchange and ultrafiltration dehydration through the semipermeable membrane characteristics of the peritoneum. Peritoneal dialysis is a process of water and solute exchange between the dialysate infused into the peritoneal cavity and the blood in the peritoneal capillaries using the principle of multi-loop balance. The transport mechanism of solutes is mainly diffusion, and the removal of water is mainly ultrafiltration. Peritoneal dialysis repeatedly replaces the dialysate to remove metabolic products and correct water-electrolyte and acid-base imbalances, thereby maintaining a constant internal environment of the body. Peritoneal dialysis is a physiological treatment method. With the continuous improvement and gradual perfection of technology, peritoneal dialysis has become an important method for the treatment of acute and chronic renal failure. The fluid exchange process includes the following steps: washing hands, preparing disinfectant, checking dialysate, connecting pipelines, draining waste fluid, flushing pipelines, filling with new fluid, disconnecting and disinfecting interfaces.

[0003] In the prior art, during peritoneal dialysis fluid exchange, three clamps are required to be opened or closed separately or simultaneously for different parts of the pipeline. During the drainage and flushing process, since the pipeline is drained first and then flushed, there is still some undischarged peritoneal dialysis fluid in the catheter in the patient's body. This part of the peritoneal dialysis fluid will provide a nutritional environment for bacteria. Especially when there is contamination during the operation, bacteria are easy to breed in the residual fluid and cause peritonitis. In addition, the residual old dialysate will dilute the newly injected dialysate, reduce the solute concentration gradient, and affect the toxin removal efficiency. Protein, fibrin or calcium precipitation in the residual fluid may adhere to the inner wall of the catheter, causing stenosis or blockage of the lumen. Summary of the invention

[0017] S1. Check the integrity of the device, confirm that the support sleeve and support column of the support assembly are firmly connected through the fixed spring, and the limit hole is not blocked. Check whether the motor and reciprocating screw rod in the adjustment box of the adjustment assembly are operating normally, whether the lifting rod and blocking plate of the control valve can be opened and closed flexibly, and verify whether the heating wire in the fixed box of the suspension assembly is operating normally to ensure that the dialysate temperature is controllable;

Hang the dialysate bag on the hook, connect the inlet tube to the outlet of the dialysate bag, the outlet tube to the patient's peritoneal catheter, and the outlet tube to the waste fluid collection bag, ensuring that the interfaces of each pipeline are tightly sealed to avoid contamination;

[0019] S3. Use the tools in the tool box to adjust the height of the telescopic column so that the position of the suspension frame is suitable for the patient's operation. Start the motor. The take-up shaft adjusts the cable length in the support sleeve through the connecting wire so that the support column stabilizes the overall structure of the support device. Open the control valve of the discharge pipe, start the motor in the adjustment box, drive the reciprocating screw rod to drive the slider to move, and the trigger rod pushes the blocking plate to open. The parallel plate capacitor sensor monitors the liquid flow rate of the output pipe in real time to ensure that the waste liquid drainage speed is uniform. The waste liquid flows into the collection bag through the discharge pipe. After the drainage is completed, close the control valve;

[0020] S4, open the control valve of the inlet pipe, the dialysate enters the outlet pipe through the regulating box, start the electric heating wire to heat to the set temperature, so that the dialysate temperature is between 37-39°C, and close the inlet pipe valve after flushing is completed;

[0021] S5. Open the inlet valve again. The motor drives the reciprocating screw to accurately adjust the position of the slider to ensure that the liquid is evenly poured into the patient's abdominal cavity. After the conductive block contacts the conductive sheet, the heating wire is activated to maintain a constant temperature of the liquid. After the filling is completed, all valves are closed, the pipeline is disconnected and the interface is disinfected.

[0022] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0023] A fixed connection is one where the parts or components are fixed without any relative movement;

[0024] A rotational connection is a connection between parts that allows the parts to rotate relative to each other;

[0025] Threaded connection is a detachable fixed connection with the advantages of simple structure, reliable connection, and convenient assembly and disassembly. It is widely used in the fields of mechanical engineering and connection structures.

[0026] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0027] Beneficial effects of the present invention:

[0028] 1. The present invention can absorb the dialysate remaining in the patient's catheter by providing an adsorption component. After the drainage is completed, the negative pressure structure can be driven by the descent of the trigger rod to absorb the residual peritoneal fluid in the patient's catheter, thereby preventing this part of the used dialysate from causing infection and other symptoms to the patient, thereby ensuring the patient's health.

[0029] 2. The present invention can simplify the dialysis fluid exchange process by setting up an adjustment component. The patient only needs to connect the peritoneal catheter to the pipeline in the device. The subsequent drainage, flushing and fluid exchange do not require the patient to operate. During flushing, the valve state is adjusted through the sensor feedback signal. This design reduces the steps of manual intervention, avoids operational errors, greatly improves the convenience of patient fluid exchange, and is suitable for the elderly and patients with limited mobility.

[0030] 3. The present invention has constant temperature control. The electric heating wire in the fixed box is linked with the conductive block. When the dialysate bag is hung on the hook, it is automatically heated to maintain the liquid temperature at 37-39°C (physiologically suitable range) to avoid abdominal pain or vasoconstriction caused by low-temperature dialysate. The anti-accidental touch design uses a spring reset mechanism for the baffle plate and lifting rod of the control valve to ensure that the valve is in a closed state during the non-operation stage to prevent liquid leakage or contamination.

[0031] 4. The telescopic column and tool box of the suspension frame of the present invention are convenient for quick installation and maintenance in different environments such as homes and hospitals. The driving motor of the fixed box cooperates with the gear groove, and the pressure of the extrusion plate is adjusted by the lifting plate. The flow rate can be adjusted for dialysates of different viscosities to meet personalized treatment needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0045] See also Figure 1 , Figure 8 and Fig. 9The peritoneal dialysis fluid exchange device comprises a support component 1, a suspension component 3 and an adjustment component 7. The top of the support component 1 is installed with a fixed cylinder 2, the outer wall of the fixed cylinder 2 is installed with an adjustment component 7, the adjustment component 7 comprises an adjustment box 70 installed on the outer wall of the fixed cylinder 2, the top of the adjustment box 70 is penetrated with an output pipe 76, the outer wall of the adjustment box 70 is penetrated with an inlet pipe 77, the bottom of the adjustment box 70 is penetrated with a discharge pipe 78, the output pipe 76, the inlet pipe 77 and the discharge pipe 78 are interconnected and the outer walls are all installed with a control valve 8, and the outer wall of the output pipe 76 is installed with a parallel plate capacitance sensor The device 710, the inner top wall of the regulating box 70 is installed with a motor 71, the output end of the motor 71 is installed with a reciprocating screw 72, the outer wall of the reciprocating screw 72 is connected with a slider 73 by a thread, the outer wall of the slider 73 is installed with a T-shaped trigger rod 79, the inner bottom wall of the regulating box 70 is installed with a slide bar 74, the outer wall of the slide bar 74 is fitted with a limit block 75, and the limit block 75 is fixedly connected to the outer wall of the slider 73, the inner wall of the control valve 8 is provided with an adjusting hole 81, the inner top wall of the control valve 8 is installed with a lifting rod 82, the outer wall of the lifting rod 82 is surrounded by a second spring 83, and the bottom of the lifting rod 82 is installed with a blocking plate 84.

[0046] Specifically, when the elderly or patients with limited mobility use the device for peritoneal dialysis fluid exchange, the patient connects the peritoneal catheter to the inlet tube 77, and then starts fluid exchange. When the peritoneal fluid in the patient's body is drained out, the trigger rod 79 is in a high position, and the trigger rod 79 contacts the control valve 8 on the outer wall of the output tube 76, so that the control valve 8 of the output tube 76 is in a closed state. At this time, the peritoneal fluid in the patient's body flows out through the inlet tube 77 and the outlet tube 78, and the control valves 8 of the inlet tube 77 and the outlet tube 78 are in an open state;

[0047] It should be noted that the pipeline is then flushed. At this time, when the parallel plate capacitance sensor 710 detects that there is no liquid flowing out of the discharge pipe 78 or the flow rate is greatly reduced, it sends a signal to the motor 71, and the motor 71 operates the reciprocating screw 72 to drive the slider 73 and the trigger rod 79 to descend. At this time, one end of the trigger rod 79 contacts the control valve 8 on the outer wall of the inlet pipe 77, and at the same time, the control valve 8 on the outer wall of the output pipe 76 is opened, and the dialysate is output to the outside through the output pipe 76 and the discharge pipe 78, thereby realizing the flushing function;

[0048] It should be noted that after flushing for 10-15 seconds, the reciprocating screw rod 72 drives the slider 73 to continue to move downward, at which time the control valve 8 on the outer wall of the discharge pipe 78 is closed, and the control valves 8 on the outer walls of the output pipe 76 and the inlet pipe 77 are opened, and the dialysate enters the patient's abdominal cavity to achieve the fluid replacement function;

[0049] It should be noted that the trigger rod 79 contacts the lifting rod 82, the lifting rod 82 descends, the second spring 83 contracts, and the blocking plate 84 blocks and seals the adjustment hole 81, thereby realizing the opening and closing functions of the pipeline;

[0050] It should be noted that in order to ensure that the pipeline is opened and closed in time, the trigger rod 79 is designed to be T-shaped. When the trigger rod 79 moves downward, the protruding part of the trigger rod 79 can continue to contact the control valve 8 on the outer wall of the output tube 76. When one end of the trigger rod 79 contacts the control valve 8 on the outer wall of the inlet tube 77, the protruding part is separated from the control valve 8 on the outer wall of the output tube 76, thereby preventing the dialysate from entering the patient's body when the pipeline has not been flushed.

[0051] See also Fig. 9 and Fig.10 The adsorption component 9 includes a fixed wheel 90 installed on the inner wall of the adjustment box 70, a pull rope is installed around the outer wall of the fixed wheel 90, a magnet 91 is installed on one end of the pull rope, a fixed cavity 92 is installed on the inner wall of the adjustment box 70, a third spring 94 is installed on the inner top wall of the fixed cylinder 92, a sealing plate 93 is installed on the bottom of the third spring 94, a No. 1 pipe 95 is installed on the top of the fixed cavity 92, a one-way valve 96 is installed on the outer wall of the No. 1 pipe 95, a No. 2 pipe 97 is installed on the bottom of the fixed cavity 92, and a one-way valve 96 with the same structure is installed on the outer wall of the No. 2 pipe 97.

[0052] Specifically, after the patient's peritoneal fluid is discharged, the pipeline is flushed. At this time, the trigger rod 79 is adsorbed with the magnet 91. When the trigger rod 79 descends, the magnet 91 is pulled down synchronously. At this time, the pull rope pulls the sealing plate 93 up through the fixed wheel 90. When the sealing plate 93 is raised, the space below the sealing plate 93 inside the fixed cavity 92 is in a negative pressure state. At this time, the one-way valve 96 on the outer wall of the No. 1 tube 95 is opened, and the peritoneal fluid remaining in the inlet tube 77 is adsorbed into the fixed cavity 92, thereby preventing the peritoneal fluid from remaining in the patient's body, so that no peritoneal fluid will remain in the patient's catheter, and the integrity of the drainage is increased;

[0053] It should be noted that after the trigger rod 79 continues to descend, the sealing plate 93 moves to the extreme position, the resistance is greater than the adsorption force between the trigger rod 79 and the magnet 91, and the magnet 91 separates from the trigger rod 79. Then the third spring 94 is no longer subjected to the tension and returns to its original length, squeezing the peritoneal fluid in the fixed cavity 92 downward. At this time, the peritoneal fluid 92 flows from the second tube 97 into the discharge pipe 78 through the one-way valve 96, and the waste fluid flows out at this time, so that after the drainage is completed, the device can use the descent of the trigger rod 79 to drive the negative pressure structure to suck out the residual peritoneal fluid in the patient's catheter, thereby preventing this part of the used dialysate from causing infection and other symptoms to the patient.

[0054] See also Figure 1 , Figure 6 and Figure 7 The support assembly 1 includes a cross-shaped support sleeve 10, a plurality of fixing springs 11 are installed on the inner wall of the support sleeve 10, a support column 12 is installed at one end of the fixing spring 11, a plurality of limiting holes 13 are opened on the outer wall of the support column 12, a fixing frame 14 is installed on the inner wall of the support sleeve 10, a guide wheel 15 is installed on the outer wall of the fixing frame 14, and the guide wheel 15 is connected to the support column 12 through a cable, a plurality of telescopic columns 21 are installed on the top of the fixed cylinder 2, a socket 22 is opened on the outer wall of the telescopic column 21, and a suspension frame 2 is installed on the top of the telescopic column 21 3.

[0055] Specifically, when using the device, the extension of the support column 12 is specifically adjusted according to the size of the venue, and the motor 6 is started. The motor 6 drives the take-up shaft 61 to rotate. During the rotation of the take-up shaft 61, the connecting line 62 is tightened, and the connecting line 62 pulls the support column 12 to shrink through the guide wheel 15. The fixed spring 11 shrinks at this time and is adjusted to a suitable position. The electric telescopic rod 64 extends to drive the block 65 to descend, and the block 65 meshes with the gear teeth of the fixed gear 63, thereby blocking the take-up shaft 61 to prevent rotation, thereby fixing the extension length of the support column 12;

[0056] It should be noted that, in the event of a power outage or damage to the motor 6, the limiting hole 13 can also be used for fixing, and the patient can insert a cylindrical rod in the surrounding environment into the limiting hole 13 to fix the length of the support column 12. Similarly, the height of the multiple telescopic columns 21 can also be fixed in the above manner;

[0057] It should be noted that the tool box 24 can store items that the patient needs to use, such as disinfectant, paper towels, and the cylindrical card column mentioned in the above process, providing a storage function.

[0058] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The suspension assembly 3 includes a fixed box 30 installed below the suspension bracket 23, a connecting rod 31 is installed on the top of the fixed box 30, and the top of the connecting rod 31 is fixedly connected to the bottom of the suspension bracket 23, a fixed slot 32 is provided on the front of the fixed box 30, a box door 33 is installed on the inner wall of the fixed slot 32 through a pin, a handle 34 is installed through the outer wall of the box door 33, and a card plate 35 is installed at the bottom of the handle 34, a fixed block 4 is installed on the inner wall of the fixed box 30, a plurality of gear slots 41 are provided on the outer wall of the fixed block 4, a first card slot 42 is provided on the back of the fixed block 4, a lifting plate 43 is slidably installed on the front of the fixed block 4, a second card slot 44 is installed on the back of the lifting plate 43, and the second card slot 44 is installed on the back of the lifting plate 43.

[0059] Specifically, the handle 34 is rotated to rotate the clamping plate 35 to a horizontal position, and then the dialysate is placed into the fixed box 30 and hung on the hook 51. At this time, the hook 51 descends, so that the conductive block 53 contacts the conductive sheet, and the heating wire 55 is energized to heat the dialysate to maintain the temperature of the dialysate. When the patient needs to speed up the fluid replacement, the driving motor 46 drives the driving gear 47 to rotate, and the driving gear 47 contacts the gear slot 41, so that the lifting plate 43 slides on the fixed block 4. At this time, the two inclined squeezing plates 45 squeeze the dialysate during the downward movement, thereby speeding up the outflow of the dialysate.

[0060] Working principle: first, when using the device, adjust the extension of the support column 12 according to the size of the venue, start the motor 6, and the motor 6 drives the take-up shaft 61 to rotate. During the rotation of the take-up shaft 61, the connecting wire 62 is tightened, and the connecting wire 62 pulls the support column 12 to shrink through the guide wheel 15. The fixed spring 11 shrinks at this time and is adjusted to a suitable position. The electric telescopic rod 64 extends and drives the block 65 to descend. The block 65 engages with the gear teeth of the fixed gear 63, thereby clamping the take-up shaft 61 to prevent rotation, thereby fixing the extension length of the support column 12, and then rotating the handle 34 to rotate the clamping plate 35 to a horizontal position, and then putting the dialysate into the fixed box 30, and hanging the dialysate on the hook 51. At this time, the hook 51 descends, causing the conductive block 53 contacts the conductive sheet, and the heating wire 55 is energized to start heating the dialysate to maintain the temperature of the dialysate. Finally, when the elderly or patients with limited mobility use the present device for peritoneal dialysis fluid exchange, the patient connects the peritoneal catheter to the inlet tube 77, and then starts fluid exchange. When the peritoneal fluid in the patient's body is drained out, the trigger rod 79 is in a high position. At this time, the trigger rod 79 contacts the control valve 8 on the outer wall of the output tube 76, so that the control valve 8 of the output tube 76 is in a closed state. At this time, the peritoneal fluid in the patient's body flows out through the inlet tube 77 and the outlet tube 78, and the control valves 8 of the inlet tube 77 and the outlet tube 78 are in an open state. The control valves 8 on the outer walls of the output tube 76 and the inlet tube 77 are opened, and the dialysate enters the patient's peritoneal cavity to achieve the fluid exchange function.
