Solvent front positioned aseptic chemical mixing clip type bottled syringe

Abstract

The invention discloses one germ-free injector, comprising one dissolvent bottle (3) and one solute bottle (8), and the bottleneck of solute bottle is connected with one slide rack (7) fixed with needle (5). It is characterized in that the dissolvent bottle is located inside the sliding sleeve (2), the sliding sleeve is matched with shell (9), and the bottleneck of dissolvent bottle and solute bottle are in relative position. The bottleneck of dissolvent bottle is equipped with one sliding rack (4) and needle insert (6), the needle insert is contact with the end surface of sliding rack. Said dissolvent is Schering bottle with pre-charged pressure, the solute bottle is cassette bottle. The invention mixes medicine in two bottles through one needle, and installs one-grade and two-grade push rod, so the structure is innovated and becomes more reasonable, the production process is more simple and cost is lower, and the operation is more easier.

Description

technical field [0001] The invention belongs to the technical field of medical injectors, and in particular relates to a solvent front type aseptic mixed drug cartridge syringe. Background technique [0002] The applicant has applied for a number of pre-filled syringes successively, and has greatly improved and innovated the structure of the traditional syringe. Medical liability accidents caused by errors, and has the advantages of convenient use and self-injection. However, most of these syringes are in contact with the solvent bottle and the push handle, and the solute bottle (must be a cartridge) is located at the front of the syringe. When the solvent enters the solute bottle through the guide needle due to pressure, the drug is mixed, and then the drug is pushed out from the solute bottle. liquid. Although the structure has been greatly improved and certain positive effects have been produced, there are still some parts such as inconvenient use and unreasonable struc...

AI Technical Summary

Problems solved by technology

Although the structure has been greatly improved and has produced certain positive effects, there are still some problems such as inconvenient use and unreasonable structure.

For example, it is necessary to have a conduction needle and an injection needle at the same time, so that the manufacturing cost cannot be minimized, and the production process is also relatively complicated.
