Abstract

The invention discloses a hypodermic syringe, which comprises a main cylinder body, a drug mixing cylinder and a needle body. Two medicine storage tanks are arranged inside the main cylinder body, and a detachable medicine liquid bottle is installed in the medicine storage tank. The medicine liquid bottle includes The liquid medicine cylinder and the piston block, the liquid medicine cylinder is pre-filled with liquid medicine, the piston block is installed on the upper end of the liquid medicine cylinder, and the piston block can move in the liquid medicine cylinder, the bottom of the liquid medicine cylinder is made of rubber material, There is a push rod above the medicine storage tank in the main cylinder body, which can push the piston block to move, and a window cover is hinged on the main cylinder body to face the medicine storage tank; the mixing tank is detachably installed on the bottom of the main cylinder body, Two puncture needles are installed on the upper end of the drug cartridge, and a drug liquid mixing chamber is provided inside the drug mixing cartridge to communicate with the puncture needles. The bottom of the drug liquid mixing chamber is provided with an injection channel. The channel is connected, and the push rod pushes the two liquid medicine bottles to inject the liquid medicine into the liquid medicine mixing chamber and mix evenly, which can quickly and uniformly prepare the mixed medicine solution and reduce the pollution of the medicine solution.

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...
