Description

Auxiliary replacing device for external short pipe of peritoneal dialysis

Technical Field

The utility model relates to a medical auxiliary instrument especially relates to an auxiliary device of changing of external nozzle stub of peritoneal dialysis.

Background

Peritoneal Dialysis (PD) is a Dialysis method that uses the peritoneum of the human body as a Dialysis membrane, and uses a PD Dialysis tube, a titanium connector and a PD short tube to establish a fluid-filling channel, and exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneum by the dialysate filled in the Peritoneal cavity, so as to remove the metabolic products and excessive moisture retained in the body, and meanwhile, supplements the substances necessary for the body by the dialysate, and achieves the purpose of kidney substitution or supporting treatment by constantly updating the Peritoneal fluid.

Peritonitis is the most common acute complication of peritoneal dialysis and is one of the major causes of failure of the membrane covered dialysis and patient death. Thus, to reduce the risk of patient infection, hospitals prescribe that PD spool replacement be necessary every six months, and that spool replacement be immediate if broken or the switch fails. At present, do not have the auxiliary device who is exclusively used in the external nozzle stub of change peritoneal dialysis, need two nurses to change jointly when changing external nozzle stub, specifically change the process as follows: the patient keeps the half-sitting position, the nurse clamps the dialysis tube close to the skin with the clip, another nurse assists to lay the aseptic treatment towel, the old short tube is disassembled, the dialysis tube (about 5 cm) at the connection part of the titanium joint and the titanium joint is soaked in the iodophor disinfectant, after the disinfection is completed, the titanium joint is taken out from the iodophor disinfectant and is wiped with aseptic gauze, the iodophor disinfectant is removed, and then a new short tube is connected to the titanium joint. The above operation has the following problems: firstly, the elderly or patients lying in bed for a long time are difficult to keep a half-sitting position all the time, and the body position of the patients is changed, so that the outer section of the dialysis tube is easy to contact with iodophor disinfectant to cause the corrosion of the dialysis tube; secondly, the titanium joint is easy to be separated from the iodophor solution due to the change of the body position of the patient in the disinfection process, so that the disinfection time is prolonged; moreover, the whole replacement process needs the cooperation of two nurses, which wastes manpower and consumes long time.
