Abdominal dialysis positioner for nephrology department

Abstract

The invention discloses an abdominal dialysis positioner for the nephrology department, which comprises a supporting tube taking a supporting effect on a human trunk model. Two symmetrical through holes are formed in the upper surface of the supporting tube; a first shaft is rotatably connected to the upper surface of the supporting tube in a limiting mode through the through holes; the surface of the first shaft is fixedly sleeved with a limiting ring; the first shaft is sleeved with a torsional spring; the two ends of the torsional spring are fixedly connected with the opposite faces of the supporting tube and the limiting ring; and a medical binding belt is wound and stored on the arc-shaped contour, located in the supporting tube, of the first shaft. Through cooperative use of the structures, the abdominal dialysis positioner for the nephrology department solves the problems that in the actual use process, traditional positioning equipment is difficult to carry out self-adaptive adjustment according to the size of the abdomen of a user, resulting in that the condition of unfirm fixing is liable to occur; and secondly, when the user is subjected to peritoneal dialysis, repeated abdominal respiration can further influence the fixing firmness degree of a peritoneal dialysis catheter, resulting in that inconvenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a peritoneal dialysis positioner used in nephrology. Background technique [0002] Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane. The dialysate poured into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum to remove retained metabolites and Excessive water, at the same time supplement the necessary substances of the body through the dialysate, and constantly update the peritoneal dialysate to achieve the purpose of kidney replacement or supportive treatment. During peritoneal dialysis treatment, the peritoneal dialysate is poured into the peritoneal cavity through the peritoneal dialysis catheter One side of the peritoneum in the peritoneal cavity is the blood containing waste and excess water in the peritoneal capillaries, an...

Problems solved by technology

[0002] Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane. The dialysate poured into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum to remove retained metabolites and Excessive water, at the same time supplement the necessary substances of the body through the dialysate, and constantly update the peritoneal dialysate to achieve the purpose of kidney replacement or supportive treatment. During peritoneal dialysis treatment, the peritoneal dialysate is poured into the peritoneal cavity through the peritoneal dialysis catheter One side of the peritoneum in the peritoneal cavity is the blood containing waste and excess water in the peritoneal capillaries, and the other side is the peritoneal dialysis solution. The waste and excess water in the blood pass through the peritoneum into the peritoneal dialysis fluid. After a period of time, put the The peritoneal dialysis solution containing waste and excess water is released from the peritoneal cavity, and then filled with new peritoneal dialysis solution, so that the cycle is continuous. During clinical peritoneal dialysis, the dialysis catheter needs to be fixed. If it cannot be fixed, the patient is prone to Peritonitis, and if the fixation is not good, the outer tube will be damaged, causing the pain of the patient's second intubation. The existing clinical peritoneal dialysis positioner used in the department of nephrology has a simple structure and single function, and cannot effectively fix the dialysis catheter. Use medical adhesive tape to fix the fastening parts, the fixing effect is not good, and the comfort of the patient is reduced

[0003] Traditional positioning equipment is difficult to adjust adaptively according to the size of the user's abdomen, and it is prone to loose fixation; secondly, when the user is performing peritoneal dialysis, repeated abdominal breathing will further affect the firmness of the peritoneal dialysis catheter fixation, giving Inconvenient to use
