Abstract

The invention relates to the field of medical equipment and especially relates to a disposable anti-pollution and anti-leakage syringe, and the syringe comprises a needle cylinder, a piston matching with the needle cylinder, and a push rod connected with the piston, wherein the syringe further comprises a sealing sleeve which is sleeved on the push rod, one end of the sealing sleeve is in closed connection with that of the needle cylinder opening, and the other end of the sealing sleeve is in closed connection with the piston or the push rod. In comparison with the traditional syringe, the syringe can effectively avoid germs from outside air or hands of medical personnel to enter inside solution so as to further prevent from bacterial infection and cross infection.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable anti-pollution and anti-leakage liquid syringe. Background technique [0002] Present syringe mainly comprises these parts of syringe, the piston that cooperates with syringe and the push rod that is connected with piston. The medical staff pushes and pulls the piston to move through the push rod to realize operations such as mixing medicine or injecting. [0003] However, the inventors have found that in the syringe of the current structure, one end of the syringe is matched with the syringe, and the other end is open to install the piston and the pull rod. In unused syringes, the piston is located at the bottom of the syringe, causing the upper part of the piston to The inner wall of the syringe is exposed to the air, so once the syringe is taken out of the packaging bag, the inner wall of the syringe is in danger of being contaminated by germs in the air; When per...
