Abstract

The automatic injection powder mixing syringe includes solvent bottle, solute bottle and syringe cap, as well as solute bottle coating, solvent bottle coating, rotary coating, the first push unit and the second push unit. Rotating the rotary coating can drive the first push unit and the second push unit, so that the needle in the syringe cap massive pierces the rubber plug in the solute bottle and that in the solvent bottle successively and the solvent under the action of the pressure flows to the solute bottle for automatic mixing. The solvent bottle coating is then rotated off, and the solute bottle with the solute bottle coating serves as one syringe. The present invention is disposable to avoid blood contamination.

Description

technical field

[0001] The invention relates to a medical injector, in particular to an injector for automatic mixing of powder injection and solvent in clinical use. technical background

[0002] Existing syringe medication is generally made into water or powder. Although the water injection is convenient to use, it has the disadvantages of inconvenient storage, transportation and short service life. Although the powder injections currently used clinically have high drug efficacy and good stability, their packaging costs are high, that is, the solute and solvent are packaged in different medicine bottles, and the following five procedures must be passed during use: (1) Take a syringe and puncture the rubber stopper of the solvent bottle (2) suck the solvent into the syringe (3) puncture the rubber stopper of the solute bottle, inject the solvent into the solute bottle, and mix well (4) inhale the mixed drug solution in the solute bottle In the syringe (5) inject the patie...
