Embodiment Construction
[0057] figure 1 Schematic diagram of the structure of an embodiment of the small automatic peritoneal dialysis machine of the present invention. Such as figure 1 As shown, the small automatic peritoneal dialysis machine of the present invention comprises irrigation and drainage channel 1, liquid supply channel 2 and waste discharge channel 3, and described irrigation and drainage channel 1, liquid supply channel 2 and waste discharge channel 3 are connected with the first three-way valve The three liquid flow ports 13 of 4 are connected in one-to-one correspondence. In this embodiment, the three liquid communication ports 13 are distributed non-uniformly. The irrigation and drainage channel 1 is also provided with an irrigation and drainage pump 6, and the irrigation and drainage pump 6 is a bidirectional pump. The liquid supply channel 2 is provided with or connected to a fluid bag 7 for containing dialysate, a heater 8 for heating the dialysate in the liquid supply channe...

The invention discloses a peritoneal dialysis treatment device and an operation method thereof, wherein the peritoneal dialysis treatment device comprises an irrigation and drainage channel, a waste drain channel and a liquid supply channel, the irrigation and drainage channel is connected with the abdominal cavity of the human body, the waste drain channel is used for draining the liquid in the irrigation and drainage channel drained from the abdominal cavity, the liquid supply channel is connected with a liquid bag which is used for holding dialyzate, each of the irrigation and drainage channel, the waste drain channel and the liquid supply channel is correspondingly connected with one of three liquid flow holes which are non-uniformly formed in a three-way valve, and each two channels are connected under certain state. The irrigation and drainage channel is further provided with an irrigation and drainage pump which is a bidirectional pump, and the liquid supply channel is further provided with a heater which is used for heating the dialyzate and a heating pump which is used for pumping the dialyzate to the heater. The peritoneal dialysis treatment device and the operation method thereof overcome the disadvantages of complex transfusion system structure, high processing precision requirement and complex operation of the existing peritoneal dialysis machine and have advantages of simple structure, easiness in processing and convenience in operation.
Description
technical field [0001] The invention relates to the field of medical instruments. Specifically, the invention relates to a small automatic peritoneal dialysis machine and an operation method thereof. Background technique [0002] Peritoneal Dialysis (PD) is one of the more effective ways of blood purification at present, and it is suitable for replacement therapy of kidney function after kidney injury in humans. Its main principle is to pour the prepared sterile and non-pyrogenic dialysate into the patient's peritoneal cavity through the catheter, use the semipermeable membrane characteristics of the peritoneum to diffuse, infiltrate, and exchange, and constantly replace the peritoneal dialysate to achieve clearing. The purpose of metabolizing waste or toxins in the body and correcting water, electrolyte, and acid-base imbalances. The working principle of peritoneal dialysis treatment is to perfuse the dialysate into the peritoneal cavity and retain it for a period of time...
