Abstract

The invention relates to the field of medical apparatuses, and discloses a combined assembly of a bottle for medicine and an injection device. The combined assembly comprises the bottle for medicine and the injection device, wherein the bottle for medicine comprises a bottle body the inner wall of which is a straight tube; a piston is arranged in the bottle body close to a bottle opening; a push plate is wrapped in the piston, and a needle guide hole is arranged in the centre of the push plate; a sealing rubber plug and a close cover are arranged at the bottle opening; the injection device comprises an injection tube; an inner needle located in the injection tube is arranged at the bottom of the injection tube, and a trocar needle is arranged outside the inner needle; the trocar needle is greater than the needle guide hole in diameter; the needle head of the inner needle extends out of the trocar needle, the tail part of the inner needle is communicated with the outlet of the injection tube, and an outer needle is arranged at the outlet of the injection tube; and the inner tube wall of the injection tube is in clearance fit with the outer edge of the bottle opening.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical bottle and an injection device assembly. Background technique [0002] As we all know, common medical bottles include ampoules, vials, and cartridges. [0003] Ampoules are glass vials sealed with flames. They are often used to store drugs for injection, vaccines, serum, etc. Its cleaning, drying, sterilization and filling processes are mature. The sealing in the filling process uses flames to heat the filled ampoules. Neck, after it melts, the ampoule is sealed with a brushed seal. However, because the sealing is heated by flame, it cannot be applied to non-heat-resistant drugs; on the other hand, in the process of potting, there is a risk of affecting the quality of drugs due to the chemical reaction of the drug solution caused by high temperature. When in use, it is necessary to use a grinding wheel to cut the neck of the bottle, break it open with bare hands or use ...
