Description

Peritoneal dialysis catheter protective sleeve

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a peritoneal dialysis catheter protective sleeve.

Background

Peritoneal dialysis is a well established technique for treating end-stage renal disease. Peritoneal infection is one of the common complications of peritoneal dialysis, and serious patients can cause death of the patient. According to medical practice, peritoneal dialysis requires aseptic manipulation. At present, when peritoneal dialysis is clinically conducted, the joint of the peritoneal dialysis short pipe and the peritoneal dialysis bag drainage pipe is exposed by about 2 cm, so that the risk of infection is increased. In the peritoneal dialysis intermission period, the joint of the iodophor cap and the peritoneal dialysis short tube has a gap, so that dust and microorganisms can not be completely separated, and even more, the situation that the iodophor cap is loosened and falls off due to the abrasion of external force occurs, on one hand, the risk of infection is increased, on the other hand, the peritoneal dialysis short tube can not be continuously used due to pollution, and the short tube which needs to be replaced is further used, so that the medical expenditure is increased. In order to fix the peritoneal dialysis catheter, a patient usually self-manufactures a waistband, a pocket is attached to the waistband, and when the peritoneal dialysis fluid drainage is not performed, the tail end of the peritoneal dialysis catheter is placed in the pocket. The use of a belt has the disadvantages that on the one hand it causes inconvenience for the patient to take a bath in a daily life, and on the other hand, since the pocket is not a disposable item, it is easy to accumulate microorganisms, also increasing the risk of infection. The Chinese patent application: CN205994790U discloses an anti-pollution peritoneal dialysis nozzle stub protection architecture, anti-pollution peritoneal dialysis nozzle stub protection architecture include the sheath nozzle stub and cup joint in sheath protective housing on the sheath nozzle stub, the inner wall of sheath protective housing is equipped with the internal thread, the external screw thread of the link of internal thread and Y shape pipeline matches in order to realize threaded connection, adhere to the annular iodophor cotton that is used for disinfection clearance and reinforcing connection seal on the inner wall of sheath protective housing. This application only uses when being fit for peritoneal dialysis drainage, and the bacterium gets into the abdominal cavity from nozzle stub and Y type pipeline junction when having avoided peritoneal dialysis liquid drainage, has reduced the infection risk, but it only provides isolated protection, and in peritoneal dialysis intermission period, iodophor cap linking department fails to obtain the protection, therefore its defect still lies in failing to provide whole journey, lasts effectual protection.
