[0002] In clinical medical settings, medical staff need to frequently mix and dissolve the drugs in vials with other liquid medicines to prepare the medicines. Therefore, in the preparation process, medical staff often use liquid medicine transfer devices to prepare the medicines.

[0003] In general, the skirt of the liquid medicine transferor is first placed over the mouth of the vial. At the same time, the puncture needle on the liquid medicine transferor will pierce through the rubber stopper of the vial so that the needle tip of the puncture needle is located inside the vial. Then connect the syringe filled with liquid medicine to the liquid medicine transferor, and then push the push rod on the syringe to make the liquid medicine in the syringe flow through the liquid medicine transferor and be injected into the vial to mix, dissolve, and prepare it with the medicine in the vial. Finally, pull the push rod on the syringe to draw the mixed liquid medicine in the vial into the syringe for subsequent use.

[0004] During the drug mixing and preparation process, although the vial is shaken and other operations are performed to allow the drugs to mix and dissolve more thoroughly, a small amount of drugs cannot be thoroughly mixed and dissolved, and still exist in the vial in the form of solid particles that cannot be observed by the naked eye. When the syringe is aspirated, these drugs that have not been completely dissolved will flow through the liquid transfer device and be directly aspirated into the syringe without any obstruction. When these liquid medicines are used for medical injections, the undissolved particles can easily cause capillary embolism, which can seriously cause fatal medical accidents. Therefore, a liquid medicine transfer device with a filtering structure is proposed to solve the above problem. Utility Model Content
