Abstract

The invention discloses a closable male Luer needleless medical taper which comprises a shell, and a female Luer taper, a sealing piece, a hydraulic stopping pressure block and a sealing ring which are arranged in the shell and are connected in sequence, one end of the female Luer taper is arranged outside the tail end of the shell, the other end of the female Luer taper is arranged in the shell and connected with the sealing piece in a matched mode, the other end, opposite to the female Luer taper, of the sealing piece is connected with the hydraulic stopping pressure block, the other end, opposite to the sealing piece, of the hydraulic stopping pressure block is connected with the shell in a matched mode, and the sealing ring is arranged on the hydraulic stopping block in a sleeving mode. According to the closable male Luer needleless medical taper, the hydraulic stopping pressing block and the shell are in sealing fit when not connected with other products, it is guaranteed that liquid cannot overflow, the problems of dripping and leaking are reduced or eliminated, and the blocking performance of a liquid conveying system on bacteria and other chippings is improved; and the sealing state of the hydraulic stopping pressing block and the shell is released to form a passage when connected with other products, and the hydraulic stopping pressing block and a injection syringe can be transferred to a ward together to protect medicines.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a closable male Luer needleless medical connector. Background technique [0002] The male Luer needleless connector is often used in the pharmacy of the hospital. When the nurse is dispensing medicine, the male Luer needleless is connected to the syringe, and then connected to the medicine bottle or medicine bag, and the medicine liquid is extracted to form a closed environment. To keep bacteria, debris and fluid leakage out, avoid contamination of the drug; at the same time, avoid the use of needles to extract the drug. There are certain risks when using injection needles. For example, nurses are easily stabbed, particles are easily generated when the injection needle is punctured, and there are also problems of sterility and liquid leakage. [0003] Because male luers typically do not self-close after priming, when the male is rapidly moved into engagement with the female, t...
