Abstract

The invention discloses a closed needle head structure, and belongs to the field of medical needle heads. The full-closed syringe needle is mainly provided with a needle body, a needle base, a sealing piece and a reset piece, the sealing piece wraps the needle opening of the needle body, the medicine liquid conduction effect is achieved only when the sealing piece and a medicine bottle are punctured, the rest is in a full-closed state, the reset piece is used for reversely pushing the sealing piece to reset, and the full-closed syringe needle can be achieved to the maximum extent in the medical liquid transfer process; liquid leakage and even liquid volatilization are effectively prevented, and the safety of the liquid needle in the conduction process is improved. The needle head structure can be connected with other medical devices such as an injector in a matched mode for use, the needle head structure can penetrate into a medical appliance to achieve liquid medicine conduction, and the needle head structure has universality and adaptability, is convenient to widely popularize, simple and compact in overall structure, convenient to produce and manufacture, low in cost, free of learning obstacles in operation and convenient to use.

Description

technical field [0001] The invention belongs to the field of medical needles, in particular to a closed needle structure. Background technique [0002] Chemotherapy drugs used to treat cancer can pose serious hazards to healthy people, especially health care workers who are exposed to long-term exposure during the preparation of chemotherapy drugs. According to the published information of BD Company in the United States, the hazards caused by exposure to dangerous drugs in the medical environment include carcinogenicity, damage to internal organs and organs, DNA damage caused by genotoxicity, reproductive problems caused by biological toxicity, and teratogenicity caused by abortion. According to data, due to long-term contact with dangerous drugs, the incidence of cancer among pharmacists and nurses is 3-10 times higher than that of the general population, and the risk of infertility and miscarriage is 2-5 times higher. [0003] In this regard, some developed countries hav...
