<p>A medicine mixer for applying drugs includes a solvent vial 12, an outer sleeve and a solute vial 11 containing powered drugs arranged to connect together. A collar 1, a flange 4 and a circular bulging portion 8 are formed on the upper, middle, and lower portion of the inside wall of the outer sleeve 2. An inner sleeve 5 with a hollow needle 3 is positioned between the flange 4 and the circular bulging portion 8. When in use, the lower end of the outer sleeve 2 is moved downwardly to the mouth 14 of the solute vial 11 and the mouth 13 of the solvent vial 12 is inserted into the collar 1 of the outer sleeve 2, making the hollow needle 3 pierce through the rubber stoppers 10, 9 consecutively so that the two vials are in fluid communication to begin the drug mixing operation. Then the outer sleeve 2 is pulled off to deliver the mixed drug solution to a transfusion bottle 15. The present invention also relates to a drug mixing and delivery device which can be repositioned automatically and a drug mixing and delivery device which can reconstitute drugs contained in a plurality of solute vials. The drug mixing and delivery device of the present invention has a simple structure with low cost and is easy to operate, and is suitable for using with ordinary commercial drug vials.</p> |
