Back pressure type medical bottle and composite element of dispensing device and injection device thereof

Abstract

The invention discloses a back pressure type medical bottle and a composite element of a dispensing device and an injection device of the back type pressure medical bottle. The back pressure type medical bottle comprises a bottle body with a straight barrel type inner wall, a first piston is arranged at the position, close to a bottle opening, in the bottle body, a blind hole is formed in the center of the outer bottom face of the first piston, and outer edge and a sealing cover are arranged on the bottle opening, wherein the sealing cover is fixed to the outer edge and used for preventing the first piston from falling off. For the other situation, the back pressure type medical bottle further comprises a second piston arranged in the middle of the bottle body, a pushing plate is arranged in second piston in a covered mode, and a needle guide hole is formed in the center of the push plate. The back pressure type medical bottle in cooperation with the dispensing device and the injection device of the back type pressure medical bottle can systematically solve the problem of secondary pollution in the dispensing process and the injecting process, and is not only suitable for being used in city hospitals, wide-range mountainous areas, countries and other places where sanitary conditions are poor, but also suitable for being used in the wild, warships, battlefields and disaster areas.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a back-pressure medical bottle and its dispensing device and injection device assembly, that is, a back-pressure cetin bottle and its dispensing device and injection device assembly. Background technique [0002] As we all know, common medical bottles include ampoules, vials, cartridges, prefilled syringes, etc. [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. The neck of the bottle, after it melts, the ampoule is sealed with a wire drawing sealing process. 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 ch...
