Oral cavity drug delivery device for periodontal mucosa

Abstract

The invention belongs to the technical field of small medical machinery, in particular to an oral cavity drug delivery device for the periodontal mucosa. The device comprises a drug bottle, wherein the upper end of the drug bottle is in threaded connection with a bottle cover, the bottle cover is in sealed connection with a catheter, one end of the catheter is connected with a connecting tube, theend, away from the catheter, of the connecting tube is connected with liquid release cotton, the side, close to the inner side of the connecting tube, of the catheter is fixedly connected with an aircompression device, the inner side, close to one side of the air compression device, of the connecting tube is rotationally connected with a pressing handrail, the inner portion of the drug bottle isin sealed connection with a liquid extracting tube, the liquid release cotton can adapt to the structural particularity in the oral cavity and can fit the wounded part, so that drug delivery is moreuniform and sufficient, since more bacteria exist in the oral cavity, the used liquid release cotton is not suitable for being used again, and the disposable product not only ensures the sanitary safety but also reduces the cleaning strength of medical workers.

Description

technical field [0001] The invention belongs to the technical field of small medical machinery, and in particular relates to an oral drug delivery device for periodontal mucosa. Background technique [0002] Oral diseases such as oral ulcers are common and frequently occurring diseases. For the treatment of oral diseases, direct drug administration is generally used. However, due to the special structure of the oral cavity, it is difficult to accurately apply the liquid medicine to the wound during administration. , if the doctor does not operate properly, the liquid medicine may be scattered to other parts of the mouth, resulting in waste of medicine and affecting the therapeutic effect; the liquid medicine in the drug delivery device is usually at room temperature, and it is very difficult for patients to use it in cold winter. Inadaptable, affecting the treatment of oral diseases; for the nozzle part, the general drug delivery device is usually fixed together, and it is o...

AI Technical Summary

Problems solved by technology

[0004] 1. The nozzle part cannot adapt to the special structure of the oral cavity, and there are many bacteria in the oral cavity, so the used nozzle is not suitable for reuse;

[0005] 2. The suction tube stands vertically in the bottle, and the suction angle is limited. When the bottle body is tilted when administering medicine, the liquid cannot be sucked well, and the suction effect is completed.
