[0003] Medical syringes are disposable medical devices. After one injection, they need to be recycled and destroyed in a standardized manner; but for now, when some unscrupulous merchants recycle, they just simply rinse the used medical syringes and then use them to inject needles. Being reused still cannot reduce the possibility of second use of medical syringes in violation of regulations

The injection needle comprises an injection cylinder and an injection push rod installed in the injection cylinder; a rubber stopper is installed at the end part of the injection push rod, the periphery of the rubber stopper is in contact with the inner cylinder wall of the injection cylinder, and an injection needle head is installed atthe end part of the injection cylinder; the injection needle also includes a drive ring, an installation groove is installed in the cylinder wall of the injection cylinder, the opening of the installation groove is in communication with the end surface, deviated from the injection needle head, of the injection cylinder, the drive ring is installed in the installation groove, and the ring surface of the drive ring is in threaded connection with the groove wall of the installation groove; an extrusion cavity is arranged in the cylinder wall of the injection cylinder, the extrusion cavity communicates with the interior of the installation groove, the interior of the extrusion cavity is provided with two abutment blocks, and the two abutment blocks are respectively provided with abutment needles; and the end part, close to the extrusion cavity, of the drive ring is the drive end, and the drive end is in contact with the two abutment blocks respectively. The injection needle can greatly reduce the possibility of secondary reuse of medical syringes.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical sanitary injection needle. Background technique [0002] Medical syringes usually include a syringe and an injection push rod installed in the syringe. A rubber stopper is installed at the end of the injection push rod. The periphery of the rubber stopper is in conflict with the inner wall of the syringe. ; By pushing and pulling the syringe, the injection can be sucked into the syringe or ejected from the injection needle. [0003] Medical syringes are disposable medical devices. After one injection, they need to be recycled and destroyed in a standardized manner; but for now, when some unscrupulous merchants recycle, they just simply rinse the used medical syringes and then use them to inject needles. Being reused still cannot reduce the possibility of secondary use of medical syringes in violation of regulations. Contents of the invention [0004] In view...
