Description

PICC dissolves bolt nursing device

Technical Field

The utility model belongs to the technical field of central vein catheterization and nursing technique and specifically relates to a PICC dissolves bolt nursing device.

Background

Clinically, 2ml of urokinase is extracted by using a 10ml syringe, the urokinase is directly connected with a catheter after air is exhausted, negative pressure is generated in the catheter after the syringe is withdrawn by 5-6ml, the catheter is clamped if a catheter clamp exists, the tail end of the catheter is reversely folded if no catheter clamp exists, the syringe is separated, the catheter is connected with the syringe after air is exhausted, the catheter clamp is opened, then the syringe is slightly replayed, so that continuous back-extraction and replay are repeated for a plurality of times, and medicine exchange is carried out by using the negative pressure in the catheter. However, this method requires 2 persons to operate in cooperation, and the catheter is repeatedly folded back or clamped to close, and the connecting syringe is replaced for many times, which easily causes the related infection of the catheter to cause phlebitis and air embolism, and has long time consumption, high probability of complications and high risk.
