Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable medicine dispensing device. Background Art

[0002] When doctors perform surgical care on patients, they often need to inject drugs into them. In order to avoid the need to manually extract and push the drug solution and inject the drug into the powder bottle through a syringe during manual dispensing, which is time-consuming and laborious, automatic dispensing devices have been introduced on the market to replace loose push-pull syringes.

[0003] According to a disclosed portable medicine dispenser (publication number: CN213759490U), in the above application, the connecting seat is pressed to connect the card seat into the "convex" shaped slide groove, and then the connecting seat at one end of the sleeve is driven by the running transmission screw to slide along the slide groove, thereby driving the piston rod to extract or inject the medicine into the injection tube, and the card seat on one side of the connecting seat moves in the slide groove, thereby effectively avoiding the shaking of the disposable syringe when it is moved during use.

[0004] However, in actual use of the above-mentioned device, after the syringe is placed into the dispenser, the needle of the syringe will be exposed to the air. During the operation, the staff needs to hold the medicine bottle and insert the needle into the medicine bottle. During this process, the staff may accidentally touch the needle with their hands or the needle may collide with an object due to operational errors, resulting in staff injury or needle contamination, which in turn affects the dispensing results. In view of this, we propose a portable dispenser. Utility Model Content
