Technical Field
The invention relates to the technical field related to multi-cavity eyedrop bottles, in particular to a manufacturing method, application and using method of the multi-cavity eyedrop bottle.
Background
Eye drops are one of the most common and commonly used pharmaceutical dosage forms for treating ophthalmic diseases at present, and the eye drops can play a direct treatment role for many ophthalmic diseases at present. With the development of society and the advancement of technology, information and intelligence will permeate every corner of our lives and works, and eyes and vision are the most important ways to obtain information. The eye drop is not only an essential medicine for treating eye diseases, but also an important means for preventing and protecting the eye diseases.
The existing bottles for containing eye drop are all in a single-cavity structure, and one eye drop bottle can only contain one eye drop or one compound eye drop. If a plurality of eyedrops are bottled by one eyedrop, the eyedrops are composed of a plurality of components, physical and chemical reactions can occur, the treatment effect is influenced, and even serious adverse effects can be caused. But it is clinically very desirable to drop a plurality of eye drops simultaneously. Therefore, the eyedrop bottle with a single-cavity structure cannot meet the clinical use requirement. How to produce a multi-cavity eyedrop bottle solves the problems that the existing eyedrop bottle has the defects and needs to be solved urgently.
