Abstract

The invention discloses a hypodermic syringe. The hypodermic syringe comprises a main cylinder body, a medicine mixing cylinder and a needle body. Two medicine storage tanks are arranged in the main cylinder body, and detachable liquid medicine bottles are installed in the medicine storage tanks. The liquid medicine bottles comprise liquid medicine cylinders and piston blocks, the interiors of theliquid medicine cylinders are pre-filled with liquid medicine, the piston blocks are installed at the upper ends of the liquid medicine cylinders, and the piston blocks can move within the liquid medicine cylinders. The bottoms of the medicine liquid cylinders are made of rubber materials. A push rod is arranged above the medicine storage tanks in the main cylinder body, the push rod can push thepiston blocks to move, and a window cover opposite to the medicine storage tanks is hinged to the main cylinder body. The medicine mixing cylinder is detachably installed at the bottom of the main cylinder body, two puncturing needles are installed at the upper end of the medicine mixing cylinder, and a liquid medicine mixing chamber is arranged inside the medicine mixing cylinder to communicatewith the puncturing needles. An injection channel is arranged at the bottom of the liquid medicine mixing chamber. The detachable needle body is arranged below the medicine mixing cylinder and is communicated with the injection channel. The push rod pushes the two liquid medicine bottles to simultaneously inject the liquid medicine into the liquid medicine mixing chamber for mixing, so that the mixed liquid medicine can be quickly and uniformly prepared, and the liquid medicine pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a hypodermic syringe. Background technique [0002] Clinically, in the existing subcutaneous injection operation, the operator uses a common syringe to draw the liquid medicine, then mixes it well, and administers it subcutaneously with years of experience in subcutaneous injection technology. However, the same syringe draws different liquid medicines for many times, and the medicines cannot be mixed evenly, which affects the effect of the liquid medicines. In the process of drawing the medicinal liquid, the ampoule bottle is opened, and the medicinal liquid is exposed to the air, which may cause contamination of the medicinal liquid. Contents of the invention [0003] Aiming at the technical problems in the prior art, the invention provides a hypodermic syringe. [0004] In order to achieve the above object, the present invention adopts the following tech...
