Problems solved by technology

However, straight tube dialysis tubes have problems such as easy drift, poor sealing, and easy clogging, which affect the dialysis efficiency and even cause serious consequences such as bacterial infection. In addition, the glucose concentration of the dialysate in the peritoneal cavity cannot be monitored in real time, which cannot guarantee the quality of the peritoneal cavity. Best results from dialysis

Embodiment Construction

[0026] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] see Figure 1-Figure 3 , this embodiment includes a catheter body 1, a glucose monitoring probe 2, and a strip-shaped liquid bag 3. One end of the catheter body 1 is a dialysis area 10, and a plurality of dialysis holes 11 are opened on the dialysis area 10, and the other end is connected to an external dialysate bag. One end of the catheter body 1 with a dialysis hole 11 is connected to the glucose monitoring probe 2. The strip-shaped liquid bag 3 is arranged in the inner cavity of the catheter body 1, and the length is not less than the length of the dialysis area 10 on the catheter body 1. The strip-shaped liquid bag 3 One end of the tube is provided with a liquid injection port 31, which is located at the end of the catheter body 1 connected to the external dialysate bag, and a rubber stopper 311 is pr...

Abstract

A peritoneal dialysis catheter, comprising a catheter body, a glucose monitoring probe and a strip-shaped liquid bag, one end of the catheter body is a dialysis area, and a plurality of dialysis holes are opened on the dialysis area, the other end is connected to an external dialysis fluid bag, and the catheter body is provided with a dialysis hole One end of the strip-shaped liquid bag is connected with the glucose monitoring probe, and the strip-shaped liquid bag is set in the inner cavity of the catheter body, and the length is not less than the length of the dialysis area on the catheter body. The catheter body is connected to one end of the external dialysate bag, and a rubber stopper is provided at the opening of the liquid injection port. The invention has the advantages that the peritoneal dialysis catheter does not float, has good sealing performance, does not block the dialysis hole, and can monitor the glucose concentration of the dialysate in the peritoneal cavity in real time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a peritoneal dialysis catheter. Background technique [0002] Dialysis is a separation and purification technique that separates small molecules from biological macromolecules by the principle that small molecules diffuse into water (or buffer) through a semi-permeable membrane. The treatment methods of permeable membrane excretion can be generally divided into hemodialysis and peritoneal dialysis. Peritoneal dialysis is a variant of artificial blood purification, where the patient's peritoneum with good blood supply is used as the body's own semipermeable membrane, and the prepared dialysate is poured into the patient's peritoneal cavity through the catheter by gravity, so that the peritoneal There is a concentration gradient difference of solute on both sides, the solute on the high concentration side will move to the low concentration side (diffusion), and the water will move...
