Abstract

The invention relates to a medical syringe. The medical syringe comprises a core rod, a piston and a cylinder. An opening used for connecting the core rod is formed in one end of the cylinder, and a conical head used for connecting a needle is arranged at the other end of the cylinder. One end of the core rod is fixedly connected with the piston and is movably inserted into the cylinder. The outer diameter of the piston is the same as the inner diameter of the cylinder. A housing fixed to one end of the cylinder is arranged on the circumferential side of the conical head. A core rod head sleeve used for protecting the conical head is arranged in the housing. A connection groove matched with the core rod head sleeve is formed in the other end of the core rod. The core rod and the core rod head sleeve are connected through the connection groove, and the function of driving the core rod to move is achieved. A clamping groove used for storing the needle is formed in the surface of the cylinder. The medical syringe has the advantages of being simple in structure, convenient to use, capable of improving the use safety and effectively protecting the conical head and the needle, and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, 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. Its biggest shortcoming is: during the production process and before medical staff use it, it is generally found that the cone of the syringe is broken, and the broken product cannot be used, and it is easy to cause the needle to be contaminated and cause medical accidents; The syringes are stored separately from the needles. A little carelessness during transportation will scatter the needles and may cause damage. Syringes may fall, causing injury to reclaimers. 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, improved saf...
