Abstract
The invention discloses a disposable drug mixing method and a syringe employing the same. The syringe comprises a solute bottle housing, a solute bottle arranged in the solute bottle housing, a solvent bottle housing, a solvent bottle which is arranged in the solvent bottle housing in an axially-slidable manner, a rubber plug which seals the solvent bottle and a needle tubing arranged between the solute bottle and the solvent bottle. The solvent bottle housing is provided with a locking position and a releasing position. The syringe also comprises a pushing element arranged in the solvent bottle housing and a spring elastically ejecting the rubber plug. When the syringe is used, the pushing element rotates to the releasing position, the spring is released and pushes the solvent bottle and the pushing element to move in the axial direction together, the pushing element pushes the needle tubing to move and enables one end of the needle tubing to be inserted into the solute bottle, at the same time, the other end of the needle tubing is inserted into the solvent bottle, and the solvent bottle and the solute bottle are conducted through the needle tubing. By means of the elastic force of the spring, the solvent is pressed into the solute bottle through the needle tubing to make the solute be dissolved. Only by arranging the pushing element and the spring which cooperate with each other, axial movement of the needle tubing and the solvent bottle can be achieved, and the structure is simple.
Description
Technical field
The present invention relates to the mixed prescription method of single use and the syringe using the method.
Background technology
Tradition is mixed the step of medicine is injected：Solvent bottle is opened, with syringe solvent is extracted out, then by syringe needle
Pipe penetrates appearance matter bottle, then releases solvent, solvent is mixed in solute bottle with solute, finally takes out again
Going out admixing medical solutions could inject in syringe to human body.Not only step is complicated for traditional mixed prescription method,
And medicinal liquid will be transferred back and forth, easily there is the generation for causing malpractice because of wrong medicine.
For this purpose, someone's meter has set the relatively simple mixing syringe of step, such as Authorization Notice No. is
