Technical Field
[0001] The utility model relates to the technical field of liquid medicine transfer devices, in particular to a sterile liquid medicine transfer device with a multi-petal tensioning buckle. Background Art
[0002] A drug transfer device is a tool used to transfer drug liquids safely and accurately. It is usually made of corrosion-resistant materials, such as stainless steel or special plastics, to ensure the quality and purity of the drug. A drug transfer device usually includes a suction tube, a connector, and a syringe. When in use, the suction tube is inserted into the drug container and connected to the syringe, and then the drug liquid is sucked in or injected into the required place through the piston of the syringe.
[0003] When transferring liquid medicine from a vial, a hole needs to be punched in advance so that the contents of the vial can be easily extracted by a suction tube. Medical staff often use manual puncture, which can easily hurt their hands. In addition, during the process of extracting liquid medicine, the needle penetrates into the rubber stopper of the vial without a fastening structure, resulting in an unstable connection between the needle and the vial, which in turn affects the transfer of the liquid medicine.

[0012] As a further preferred embodiment of the technical solution, an elastic member is embedded and connected to one inner side of the slot, and a wedge block is embedded and connected to the other side of the elastic member.
[0013] As a further preferred embodiment of the present technical solution, the inner wall of the limiting cylinder is fixedly connected to a limiting ring and is flush with the lower side of the second clamping slot.
[0014] In the above technical solution, the limiting column on the extrusion plate enters the second card slot by squeezing the elastic member and the wedge block, which can limit the extrusion plate to prevent the subsequent movement of the extrusion plate from causing the needle to slip out of the vial, further improving the efficiency of liquid medicine transfer.
