Abstract
A device for automatically mixing powder for injection, includes an injector body, a solvent bottle, a needle, a first impelling unit and a second impelling unit. The injector body has a solute bottle and its mouth is opposite the mouth of the solvent bottle. The first impelling unit is disposed upon the solvent bottle. The second impelling unit is sleeved with a needle and located between the mouth of solute bottle and mouth of solvent bottle. A first and a second impelling sleeve-are driven by the solvent bottle to slide along the solute bottle, so the first end of the needle is fixed and extend through the solute bottle. The solvent bottle drives the first impelling sleeve and second impelling sleeve to turn with each other. The second impelling sleeve slides opposite the first impelling sleeve to make the second end of the needle extend through the solvent bottle.
