[0002] The APD machine, or Automated Peritoneal Dialysis machine, is a medical device used for peritoneal dialysis. The APD machine injects dialysate into the patient's abdominal cavity, using the peritoneum as a dialysis membrane to allow waste and excess water in the body to enter the dialysate through the peritoneum, and then draws the dialysate out of the abdominal cavity, thereby achieving the purpose of removing metabolic waste and excess water from the body.

[0003] For example, the Chinese patent authorization announcement number CN108355189B, a peritoneal dialysis tube includes a dialysis inner tube and an external pipe that can be threadedly connected, the dialysis inner tube includes a fluid exchange tube located at the end and a fixed tube located in the middle, two polyester sleeves for fixing the dialysis inner tube are arranged on the fixed tube, the contour of the fluid exchange tube is arranged in a conical spiral structure, a plurality of fluid permeable holes are arranged on the outer wall of the fluid exchange tube, and the fluid permeable holes are distributed along the length direction of the fluid exchange tube, a magnetic part and a magnetic part that can produce magnetic adsorption with the magnetic part are arranged at the end of the fluid exchange tube, a titanium coating with good biocompatibility is arranged on the outer wall of the magnetic part, and the magnetic part located in the human abdominal cavity can keep the dialysis inner tube in a relatively stable position when it is attracted to the magnetic part located outside the human body, or the position of the dialysis inner tube in the abdominal cavity can be adjusted in the process of moving the magnetic part.

[0055] The monitor 5 is connected and controlled with an ADP machine (not shown) via wireless signals for data transmission.

[0056] The working principle of the present invention is as follows: first, the moving block 303 is pulled, and the moving block 303 adjusts its position along the slide groove and the guide column 306 on the protective plate 300, and the pressing block 305 is pulled, and the pressing block 305 moves along the slide groove of the moving block 303 to squeeze the limit spring 304, and the peritoneal dialysis tube 4 passes through the pressing block 305 and the middle part of the protective plate 300, and the pressing block 305 is released, and the pressing block 305 presses the peritoneal dialysis tube 4 through the reverse thrust of the limit spring 304 to prevent the peritoneal dialysis tube 4 from falling off;

[0057] Push the peritoneal dialysis tube 4 clamped by the pressure block 305 and the protective plate 300 into the connection groove 10 provided on the connection block 1 9 through the connection block 2 302, so that the peritoneal dialysis tube 4 clamped by the pressure block 305 and the protective plate 300 is connected to the base frame 1;

[0058] When the patient presses on the protective plate 300, the protective plate 300, the extension plate 301, and the connecting block 2 302 squeeze the connecting block 1 9, and the connecting block 1 9 squeezes and moves downward along the limiting column 7 and the slide groove inside the decompression component 2. The protective plate 300 moves downward into the decompression component 2 with the peritoneal dialysis tube 4 clamped and limited by the pressing block 305. The protective plate 300 moves downward and then moves downward with the push rod 6. The push rod 6 moves downward and then presses one end of the prying connecting rod 18 downward, and the other end of the prying connecting rod 18 pries the sliding plate 15. The sliding plate 15 moves along the guide groove 19 with the L-shaped connecting rod 17 and the connecting column 20 to make the prying connecting rod 18 tilt upward, and the sliding plate 15 moves along the fixed plate 13 and the circular groove 11 with the connecting shaft 14 and the conical block 12 to squeeze the limit spring 2 16, so that the conical block 12 moves out of the circular groove 11 and pushes the part pressed by the patient, so that when the patient squeezes the peritoneal dialysis tube 4, the peritoneal dialysis tube 4 can sink to avoid the squeezing problem, and when the peritoneal dialysis tube 4 sinks, the conical block 12 extends out to push the patient to remind the patient;

[0059] When the protective plate 300 sinks, it moves with the moving block 303. When the moving block 303 moves to the top of the support plate 201 and squeezes the support plate 201, the support plate 201 first performs initial buffering and decompression through the damping rod 207 and the damping spring 208. The support plate 201 is squeezed and moves downward. The support plate 201 moves downward with the sliding block 202. The sliding block 202 tilts and pushes the auxiliary block 203. The auxiliary block 203 moves along the slide groove at the bottom of the decompression component 2 and squeezes the damping spring 1 204 and the damping rod 1 205 to obtain secondary buffering and decompression. When the patient accidentally squeezes the device, most of the pressure can be reduced through two buffering and decompression to avoid damage to the device due to excessive pressure.

[0060] When the peritoneal dialysis tube 4 drops to a certain level, the monitor 5 monitors the pressure received by the peritoneal dialysis tube 4 through the pressure sensor, and transmits the data of the pressure sensor to the central processor in real time through the data transmission module to ensure the timeliness and accuracy of the data. At the same time, the central processor is responsible for receiving, processing and analyzing the data, and the alarm is sounded to remind the patient through the alarm;

[0061] When the patient finds the squeezing and releases the squeezing, the connecting block 9 moves upward along the limit column 7 and the inner slide groove of the base frame 1 through the reverse thrust of the limit spring 8, and the connecting block 9 moves upward to return to the original position with the protective plate 300 and the clamping block 305 clamping the peritoneal dialysis tube 4, and the protective plate 300 moves downward with the push rod 6, so that the sliding plate 15 moves along the guide groove 19 with the L-shaped connecting rod 17 and the connecting column 20 through the reverse thrust of the limit spring 2 16 to return to the original position, and the prying connecting rod 18 restores the original inclination angle, and the sliding plate 15 moves downward along the fixed plate 13 and the circular groove 11 with the connecting shaft 14 and the conical block 12, so that the conical block 12 moves into the circular groove 11 and is exposed to cause squeezing discomfort to the patient again.

[0062] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
