<p>A syringe for powder injection comprises a syringe barrel(11) with a needle(2) mounted thereon, and a medication vial which is divided into an upper chamber(12) and a lower chamber(7). There a sealing means between the chambers and at the opening of the bottle. The nipple section(20) of the syringe barrel(2) is inserted into a clipping bore of the sealing means at the opening of the vial. The needle(11) of the syringe barrel(2) is mounted in the upper chamber(12) of the medication vial. A safety means is mounted between the syringe barrel(2) and the double-chamber, which prevents the relative movement of them. When the syringe is being used, as long the safety means between the syringe barrel(2) and the dualchamber is broken, the syringe barrel(2) can be pushed to allow the needle(11) to be inserted into the lower chamber(7). As the pushing rod(1) of the syringe barrel(2) is pushed further, the solvent(14) is allowed to mixed with the powder(13). After the solution is uniform by shaking, injection can be performed with the needle being pulled out. Therefore, the syringe of the present invention has a simple structure and can be operated conveniently. Moreover, it will not cause recontamination, and it is safe and trustable to use.</p> |
