Abstract

The invention relates to a safety syringe. The safety syringe comprises a needle cylinder, a push rod and a needle tool. The push rod can pass through the needle cylinder in a movable manner; the needle tool can sleeve in the front end of the needle cylinder in a detachable manner; one end of the push rod is provided with an elastic body and a push column protruded out of the elastic body; when the front end of the push rod moves toward the needle tool, the elastic body is pressed to be elastically deformed and is abutted against the needle cylinder, so that the push column passes through the needle cylinder and pushes the needle tool in order to make the needle to seperate from the needle cylinder.

Description

technical field [0001] The invention relates to a syringe, in particular to a safety syringe. Background technique [0002] In order to avoid the reuse of syringes, the syringes must be separated and recycled. However, many medical staff and medical waste disposal personnel are often stabbed by syringe needles due to improper handling, and even infected with blood such as AIDS, hepatitis B, tuberculosis, and AIDS. infectious disease. In order to avoid the occurrence of the above-mentioned incidents, various types of safety syringes have appeared on the market now. Most of the safety syringes that appear on the market are structurally designed to pull the needle of the syringe back into the syringe, but this complex structural design relatively increases the manufacturing cost. For syringes that need to be discarded after one use, the cost is high The syringes appear to be less practical. [0003] Therefore, aiming at the possible improvements of the above-mentioned defici...
