Description

technical field [0001] The invention relates to a medical device, in particular to a vaginal drug injector for treating gynecological diseases. Background technique [0002] Vaginal drug delivery device is an important part of medical equipment in foreign countries. According to the difference in drug properties and the difference in usage and dosage, foreign vaginal drug delivery devices have various shapes, but the main structural parts of most devices are mostly in the shape of injectors. This kind of drug delivery device generally has two ways of feeding medicine: one is to directly design a medicine storehouse in the device, and the medicine is stored in the medicine storehouse when it leaves the factory, and can be used directly after opening the package of the drug delivery device. , the drug needs to be stored in the drug delivery device for a long time, so this method has certain restrictions on the physical and chemical properties of the drug and the preservation ...

AI Technical Summary

Problems solved by technology

This kind of drug delivery device generally has two ways of feeding medicine: one is to directly design a medicine storehouse in the device, and the medicine is stored in the medicine storehouse when it leaves the factory, and can be used directly after opening the package of the drug delivery device. , the drug needs to be stored in the drug delivery device for a long time, so this method has certain restrictions on the physical and chemical properties of the drug and the preservation effect is poor; the second is to package the drug separately (generally use aluminum-plastic tube or aluminum tube), and put it before use. The drug is injected into the drug delivery device and then used. This drug delivery device can guarantee the quality of the drug, but the design of the current device is relatively rough, resulting in more drug residues in the device, especially not suitable for non-professionals.
