Improved peritoneal dialysis device

Abstract

The invention discloses an improved peritoneal dialysis device, which comprises a liquid medicine bag. An infusion tube is arranged below the liquid medicine bag; a dropper is arranged on infusion tube; a pulley type switch is arranged below the dropper; the infusion tube penetrates through the pulley type switch; a pipe clamp is arranged below the pulley type switch; the infusion tube also penetrates through the pipe clamp; a main pipe and a waste liquid pipe are arranged at the top end of the infusion tube; the infusion tube is connected with the main pipe and the waste liquid pipe in a Y-shaped pipe mode; a connector is arranged at the top end of the main pipe; a pipe clamp is also arranged on the waste liquid pipe; and a thermochromic disc is arranged below the waste liquid pipe and connected with a waste liquid bag. The peritoneal dialysis device can clearly observe the peritoneal dialysis liquid injection flow velocity; tube blockage is avoided; observation, control and scheme adjustment during peritoneal dialysis operation are facilitated; the liquid inlet amount of a peritoneal dialysis liquid is conveniently observed; peritoneal dialysis related specimens are convenientlyand accurately reserved; specimen data accuracy and sterility are improved; and with the arrangement of the thermochromic disc on the waste liquid pipe, whether a waste liquid is discharged or not canbe judged by observing discoloration.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to an improved peritoneal dialysis device. Background technique [0002] With the continuous development of modern society, chronic kidney disease has gradually become a common disease, which often requires peritoneal dialysis (PD, referred to as peritoneal dialysis) for treatment. Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane. The dialysate infused into the peritoneal cavity exchanges solutes and water with the plasma components of the capillaries on the other side of the peritoneum to remove residual metabolites and excess water in the body, and at the same time replenish the necessary substances for the body through the dialysate. Through continuous renewal of peritoneal dialysis fluid, the purpose of renal replacement or supportive treatment can be achieved. Peritoneal dialysis has become an important renal replacement ther...

Problems solved by technology

Existing peritoneal dialysis devices have non-integrated peritoneal dialysis devices, which cannot control the exhaust speed and liquid intake speed before liquid intake, which is not conducive to specimen retention. The fluid bag has no capacity scale, insufficient liquid discharge, and patients cannot control liquid intake. Exhaust speed and liquid inflow speed before, resulting in a waste of peritoneal dialysis fluid, the waste fluid bag section does not retain the specimen port, which is not conducive to specimen collection, the peritoneal dialysis fluid bag has no capacity scale, and the infusion and extraction capacity cannot be clearly seen. It is impossible to accurately judge the amount of inflow, and for patients undergoing peritoneal balance experiments, it is impossible to accurately judge the amount of outflow, and the outlet tube cannot clearly and accurately judge whether the liquid is still being drained, which leads to easy misjudgment and insufficient draining of the patient. In view of this situation, An improved peritoneal dialysis device is now proposed
