Abstract
The safety syringes with retractable needle refer to the needle retracted to the barrel of needle cannula, and is composed of a barrel, a connector base and a plunger, in which the barrel contains multiple diameter chambers and formed a stopping apparatus. One end of the connector base placed a protruded tube to connect needles, and the other end formed a chamber-like embedding structure, with several lever fragments. The connector base is placed within the chamber of the barrel, and one end of the lever fragment and the stopping apparatus within the barrel formed a prop for positioning. The plunger is placed in the barrel chamber, and can move axially. When the plunger moves to one end of embedding structure in the connector base, the front-end of the plunger will move other lever fragments to lift the positioning of lever fragments and barrel, and the plunger can buckle with the connector base. Therefore, if the plunger moves backward, the connector base and the needle can be pulled within the barrel for a safe storage of needles after use.
