Automated peritoneal dialysis machine

Abstract

An automatic peritoneal dialysis machine comprises a dialyzate bag, a heater, a waste liquid bag, a safety detector, a first valve, a second valve and a third valve. Dialyzate in the dialyzate bag is heated to the set temperature through the heater, the first valve and the second valve are opened, the third valve is closed, the heated dialyzate flows into an abdominal cavity of a patient, when the pouring amount of the dialyzate reaches the preset value, the first valve is closed, the dialyzate stays in the abdominal cavity of the patient to conduct dialysis and diffusion, when the time that the dialyzate stays in the abdominal cavity of the patient reaches the preset time, the first valve and the third valve are opened, the dialyzate exchanged in the abdominal cavity is led out of the waste liquid bag, and after the amount of the led-out dialyzate is consistent with the amount of the poured dialyzate, the first valve and the third valve are closed. The safety detector leads out the dialyzate exchanged in the abdominal cavity and conducts blood leakage detection on the dialyzate exchanged in the abdominal cavity. The machine effectively ensures the safety state of the patient in the dialysis process, and improves the dialysis efficiency.

Description

technical field [0001] The invention relates to medical technology, in particular to an automatic peritoneal dialysis machine. Background technique [0002] At present, hemodialysis and peritoneal dialysis are used in the treatment of uremia. At present, more than 99% of the peritoneal dialysis treatments performed clinically in my country use manual operations. Manual operations are easy to cause pollution and cause patients to be infected. Peritoneal infection is the most common cause of peritoneal dialysis. A common and serious consequence is that peritoneal sclerosis loses the function of exchange. Automated peritoneal dialysis uses a cycler (peritoneal dialysis machine) to exchange fluid at night, and keeps the dialysate in the abdomen during the day, which is called automated peritoneum. Currently, imported The fully automatic peritoneal dialysis machine, because its liquid injection method is to use air pressure to make the dialysate enter the peritoneal cavity, and use...

Problems solved by technology

[0002] At present, hemodialysis and peritoneal dialysis are used in the treatment of uremia. At present, more than 99% of the peritoneal dialysis treatments performed clinically in my country use manual operations. Manual operations are easy to cause pollution and cause patients to be infected. Peritoneal infection is the most common cause of peritoneal dialysis. A common and serious consequence is that peritoneal sclerosis loses the function of exchange. Automated peritoneal dialysis uses a cycler (peritoneal dialysis machine) to exchange fluid at night, and keeps the dialysate in the abdomen during the day, which is called automated peritoneum. Currently, imported The fully automatic peritoneal dialysis machine, because its liquid injection method is to use air pressure to make the dialysate enter the peritoneal cavity, and use negative pressure to suck out the elicited liquid, which will easily cause the peritoneal dialysis tube to be blocked by the adhesion of its inner membrane, and the waste liquid will not be drawn out completely, resulting in stasis Medical malpractice due to high intra-abdominal pressure

At the same time, since the automatic peritoneal dialysis is treated at home and is started before going to bed until dawn, the current equipment has not monitored the bleeding or infection during the treatment, which may lead to the possibility of medical accidents
