Automated Peritoneal Dialysis Detection Method for Abdominal Empty

Abstract

The invention discloses an abdominal cavity evacuation detection method for automatic peritoneal dialysis. The method includes the steps that firstly, each strand of drainage flow values are sampled, then difference value comparison is conducted on the adjacent strands of flow values, and the absolute value of the difference value is recorded as delta i; (1) when delta i is equal to 0, in other words, the drainage flow is free of the value change, drainage is normal; (2), when delta i is larger than 0 and Li+1 is not equal to 0, delta i+1 is equal to 0, for n is larger than i+1, if delta n is larger than 0, delta n+1 is equal to 0, Ln+1 is equal to 0, a strand of dialyzate is injected into the abdominal cavity, if injection is smooth, liquid is evacuated, or else a pipeline is blocked; if delta n is larger than 0, delta n+1 is equal to 0, Ln+1 is not equal to 0, and difference value comparison is continued; (3), when delta is larger than 0 and Li+1 is equal to 0, the position is not straight or the pipeline is blocked. All the strands of drainage flow sampled values of automatic peritoneal dialysis equipment are subjected to contrastive analysis, and the three states of patient abdominal cavity evacuation, pipeline blockage and the poor patient body position can be accurately judged.

Description

technical field

[0001] The invention relates to the field of peritoneal dialysis, in particular to a method for detecting the emptying of the abdominal cavity of automatic peritoneal dialysis. Background technique

[0002] Peritoneal dialysis is a procedure used to remove toxic substances and metabolites excreted by the kidneys and to help regulate fluid and electrolyte balance. Automated peritoneal dialysis is to inject peritoneal dialysis fluid into the peritoneal cavity of a person through the automatic peritoneal dialysis equipment connected to the dialysis line to achieve peritoneal dialysis.

[0003] The automatic peritoneal dialysis equipment connects the patient-side pipeline, dialysate bag and waste bucket through the dialysis tube group, and automatically injects the peritoneal dialysate into the patient's peritoneal cavity. The dialysate will cross the peritoneum and the high concentration of toxic substances and metabolites in the patient's blood in the patient's...
