Devices for delivering peritoneal dialysis fluid

Abstract

The present invention relates to the technical field of medical devices, in particular to a device for infusing peritoneal dialysis fluid, comprising a support unit, an infusion pump unit, a detection unit for the number of infusion drops, a bracket unit and a bubble detection unit, the support unit is arranged horizontally, and the The infusion pump unit is fixedly installed on the upper part of the support unit, the infusion drop detection unit is arranged above the infusion drop detection unit, the bracket unit is fixed on the upper part of the support unit, the air bubble The detection unit is arranged below the infusion drop count detection unit. The present invention can avoid the inconvenience caused by hanging the 4000ml bagged peritoneal dialysis solution on a higher infusion stand, and can adjust the extrusion speed of the extrusion mechanism. To control the infusion speed of peritoneal dialysis fluid delivered to patients, the infusion speed can be monitored, and the presence or absence of air bubbles inside the infusion tube can be monitored, thereby eliminating potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a device for infusing peritoneal dialysis fluid. Background technique [0002] In peritoneal dialysis, the peritoneum is used as a semipermeable membrane, and water and solutes are exchanged between peritoneal capillaries and dialysate. Electrolytes and small molecules move from the side with high concentration to the side with low concentration (diffusion), and water molecules Movement from the side with low osmolarity to the side with high osmolarity (osmosis). Increasing the concentration of dialysate can achieve the purpose of removing water from the body. Through the solute concentration gradient, the uremic substances in the blood can be removed from the dialysate, and the electrolyte and acid-base balance can be maintained, replacing some of the functions of the kidneys.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when patients infuse peritoneal dialysis fluid, they usually hang the bagged peritoneal dialysis fluid on the infusion stand. Due to the problem of the concentration of the peritoneal dialysis fluid itself, the speed of infusion is relatively slow. To ensure the speed of infusion, it is necessary to hang the bagged peritoneal dialysis solution on a higher infusion stand. However, the bag size of the peritoneal dialysis solution in the prior art is generally 4000 ml. , it is not easy to hang the 4000ml bagged peritoneal dialysis solution on a higher infusion stand, so it brings inconvenience to the work of the shorter medical staff; secondly, hang the bagged peritoneal dialysis solution on the infusion stand The rack completely uses gravity to infuse the peritoneal dialysis solution for the patient, which cannot effectively control the infusion speed of the peritoneal dialysis solution. In addition, hanging the bagged peritoneal dialysis solution on the infusion stand cannot monitor the infusion speed, nor can it monitor the infusion rate. Monitor whether there are air bubbles in the tube, there are potential safety hazards
