Technical Field
The utility model relates to the technical field of medical nursing articles for use, in particular to a peritoneal dialysis catheter connecting clamp.
Background
Peritoneal Dialysis (PD) is a type of dialysis that uses the peritoneum of the human body itself as a dialysis membrane. The dialysate filled into the abdominal cavity exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneal cavity, thereby removing the metabolites and excessive moisture retained in the body, and simultaneously supplementing the substances necessary for the body through the dialysate. The aim of kidney substitution or supporting treatment is achieved by continuously updating the peritoneal dialysis solution.
In the existing hospitals, when the peritoneal dialysis is performed on a patient, the patient needs to establish a passage to perform the dialysis, and the passage consists of two parts, namely a permanently-retained peritoneal dialysis tube and a peritoneal dialysis external short tube which are connected in sequence. In the process of peritoneal dialysis, a patient needs to replace peritoneal dialysis solution three to five times every day, so the most easily damaged parts with the highest use frequency are the connection part of the external short pipe end of the peritoneal dialysis and the connection part of the peritoneal dialysis pipe end;
the existing peritoneal dialysis catheter generally comprises an internal thread connecting port, a circular connecting part A, a circular connecting part B, a conical table-shaped connecting part and a dialysis catheter body which are sequentially connected from front to back; the outer diameter of the internal thread connecting port is equal to the outer diameter of the circular connecting part B and is larger than the outer diameter of the circular connecting part A; the front end of the conical frustum-shaped connecting part is in smooth transition with the rear end of the circular connecting part B; two grabbing lugs integrally formed with the circular connecting part A are fixedly arranged on the outer wall of the circular connecting part A in an opposite mode;
for the peritoneal dialysis tube, during operation, a clamping forceps is generally required to be clamped outside the circular connecting part A to screw the peritoneal dialysis tube to be in threaded connection with the end of the corresponding peritoneal dialysis external short pipe, while the traditional clamping forceps are ordinary forceps bodies, the structure of the traditional clamping forceps is similar to that of a common vice, and although the traditional clamping forceps are widely used, the traditional clamping forceps still have certain defects and shortcomings;
particularly, on the one hand, the two opposite clamping surfaces can only clamp the outer lug of the corresponding circular connecting part A generally, so that the clamping stability is not good, the clamping is easy to slip, and on the other hand, the corresponding circular connecting part A and the outer surfaces of the two corresponding lugs on the outer part of the corresponding circular connecting part A are easy to wear when the clamping slips, so that the corresponding peritoneal dialysis catheter is easy to damage and the service life is short.
