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...

Abstract

The invention discloses and provides a mini automatic peritoneal dialysis machine and an operation method thereof. The mini automatic peritoneal dialysis machine comprises an irrigation and discharge channel communicated with an abdominal cavity of a human body, a waste discharge channel for discharging the liquid discharged from the abdominal cavity through the irrigation and discharge channel, and a liquid supply channel for being connected with a liquid bag accommodating dialysate. The irrigation and discharge channel, the waste discharge channel and the liquid supply channel are correspondingly connected with three liquid flow openings in non-uniform distribution of a first three-way valve. The irrigation and discharge channel further comprises a two-way irrigation and discharge pump. The liquid supply channel further comprises a heater, a heat pump and a second three-way valve, and the second three-way valve is connected with a circulation channel which is connected with the liquid supply channel. The mini automatic peritoneal dialysis machine and the operation method thereof solve the technical problem by overcoming the disadvantages of complex system structure, high machining accuracy requirements and complex operations of an existing peritoneal dialysis transfusion system.

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 methods of blood purification at present, and it is suitable for replacement therapy of renal function after renal 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 tim...
