Syringe needle

Abstract

The invention discloses a syringe needle. The syringe needle comprises a separation structure, a needle body, a head part, an infusion opening and a protection shell, wherein the head part is arranged at the top end of the needle body; a puncture head is fixed to the top end of the head part; a tail part is arranged at the bottom end of the needle body; a fixed head is fixed to the bottom end of the tail part; a needle base is fixed to the bottom end of the fixed head; a second shoulder part is fixed to the bottom end of the needle base; a first shoulder part is arranged below the second shoulder part; a connector is fixed to the bottom end of the first shoulder part; and the top end of the first shoulder part is connected with the bottom end of the second shoulder part through mucilage glue. According to the invention, the convenience of pulling out the needle is improved, the situation that the needle body stabs a medical staff is reduced, the pollution to the needle body when the needle body is placed is reduced, impurities and sediments are prevented from being injected into the body of a patient, residues of liquid medicine in a bottle are reduced when the liquid medicine is extracted, and the situation that the infusion opening is blocked by tiny rubber particles when the liquid medicine is extracted is avoided.
