AI Technical Summary

Technical Problem

During oral medication administration, patients often find it difficult to maintain an open mouth for extended periods. Conventional mouth openers require doctors to operate with one hand, and mouth support devices cannot be precisely adjusted or stably positioned, affecting the efficiency and accuracy of medication administration. Furthermore, the lack of effective oral lighting makes the procedure inconvenient.

Method used

A dental drug delivery device was designed, which integrates mouth support and drug delivery functions by combining a sliding connection component with a mouth support plate. An angle adjustment and fixation are achieved by using a cross-hinged diagonal bar and a guide slip ring structure. It is equipped with an oral lighting component. The drug delivery needle is rigidly supported by a movable support column and a positioning collar, and a quick disassembly and assembly structure is set.

Benefits of technology

It achieves stable oral cavity opening and improved drug delivery accuracy, simplifies the operation process, improves drug delivery efficiency and accuracy, provides a clear view inside the oral cavity, simplifies the replacement and cleaning of consumables, and enhances the convenience and safety of operation.
