The invention discloses an integrated safety syringe, belongs to the technical field of medical supplies, and solves the problems that a syringe is inconvenient and unsafe to operate, needling events and pollution easily happen, a needle stem is easily fractured, and nurses beginning to learn do not easily grasp injection depth in the prior art. The syringe comprises a core rod, a jacket, a syringe needle and a needle cap, a conical head is arranged at the front end of the jacket, the syringe needle is fixed on the conical head, the needle cap is connected on the conical head in a clamped manner and used for sleeving the syringe needle, a first clamping part is positioned at a joint between the conical head and the syringe needle, a third clamping part is positioned on the root of the conical head, a second clamping part is positioned between the first clamping part and the third clamping part, the distance between the third clamping part and the first clamping part is 2 / 3 times of the length of the syringe needle, a semicircular flange is arranged at the opening end of the needle cap, the other end of the needle cap is closed by the aid of a silicone section, the length of the needle cap without the silicone section is as same as that of the syringe needle, and the distance between the second clamping part and the first clamping part is larger than the thickness of the silicone section. The syringe is simple in structure, scientific and reasonable in design and convenient to operate.
Description
technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to an integrated safety syringe. Background technique [0002] In the prior art, the syringe and the needle are separated. When in use, the needle seat covered with the needle cap is installed on the cone of the syringe, and then the needle cap is pulled out to expose the needle; after use, the needle cap is put back on Needle hub, place the needle in the needle cap. During actual operation, it is difficult to control the strength of pulling out the needle cap, and the nurse is easily stabbed by the needle. In addition, after the syringe is used, when the needle cap is put back on the needle, because the needle is small, it is easy to slip, thus stabbing the nurse and increasing the risk of infection. Therefore, it is generally not recommended for nurses to return the needle cap after using the syringe clinically. However, nurses do not return the needle caps...
