Abstract

The invention relates to a medical injector. The medical injector comprises a mandrel, a piston and a barrel body; one end of the barrel body is equipped with an opening for connecting the mandrel, and while the other end of the barrel body is equipped with a cone head for connecting a needle; one end of the mandrel is fixedly connected with a piston and can be movably inserted into the barrel body; the outside diameter of the piston is equal to the inside diameter of the barrel body; a mandrel head sleeve is fixedly connected to the mandrel; a mounting trench for storing the needle is arranged in the mandrel; a protecting layer for protecting the needle is arranged on the inner wall of the mounting trench. The medical injector has the characteristics of being simple in structure, convenient to use, and high in safety in use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical injector. Background technique [0002] Syringe is a kind of utensil commonly used in medical equipment, although it has advantages of simple structure and convenient use, its disadvantages are also very prominent. The syringes in the prior art are stored separately from the needles. A little carelessness during transportation will scatter the needles and may cause damage; the used syringes will be discarded, and the used needles will be recycled During the process, the syringe in front may fall, causing injury to the recovery personnel. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a medical syringe with simple structure, convenient use and improved safety in use. [0004] Realize the technical scheme of the present invention as follows: [0005] A medical syringe, including a core r...
