Description

Technical Field

[0001] The utility model relates to the technical field of oral mucosa, in particular to a local drug delivery device for treating oral submucosal fibrosis. Background Art

[0002] The oral mucosa is a pink, soft and moist tissue that covers the entire inside of the mouth. It is connected to the skin externally and to the mucosa of the digestive tract internally. It has some characteristics of the skin and some characteristics of the mucosa of the digestive system. The oral mucosa plays multiple functions in the human body, including forming a protective barrier, sensory function, secreting digestive juices, and immune function.

[0003] As disclosed in the announcement number CN220175847U, a local drug delivery device for oral internal medicine treatment has the following beneficial effects: 1. A limiting disc and a drug outlet head are provided, so that when the device is working, the limiting disc is pressed against the surface where medicine needs to be applied, and then the medicine liquid is introduced into the drug outlet head by pushing the medicine outlet push plate and the medicine outlet piston. The medicine outlet head sprays the medicine evenly through the medicine outlet of the medicine outlet ball on the surface, thereby improving the uniformity of medicine application, and the excess medicine liquid is collected and blocked by the limiting disc to prevent the patient from accidentally ingesting the medicine liquid, thereby improving the practicality of the device; 2. A drug suction hole and a transmission screw are provided, so that after the drug application is completed, the device can drive the reflux piston at one end to slide by rotating the transmission screw, so that the reflux piston extracts excess medicine liquid through the reflux pipe, so that the excess medicine liquid enters the reflux pipe from the drug suction hole and finally enters the collection The medicine can be collected in a tube for subsequent recycling; 3. A covering ring and a connecting step are provided, so that the device is connected and fixed by the threads on the opposite surfaces of the covering ring and the connecting step. The sealing of the device is improved by covering the connecting step with the covering ring, and the device can be quickly disassembled and installed by rotating the mounting baffle, which is convenient for cleaning the device and replacing different drug delivery tubes for use, thereby improving the applicability; however, the above patent lacks a structure for quantitative drug administration.
