Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to an oral cavity waterproof patch.
Background
At present, a series of novel treatment methods appear in the oral medical profession, and the oral mucosa lesion has very effective treatment effect, such as photodynamic treatment. However, photodynamic therapy requires wet application of a medicine for an intraoral lesion for more than 3 hours, and in order to prevent the medicine from being affected by saliva, a plurality of layers of rice paper, gauze, preservative films and the like need to be applied up and down, and a patient needs to keep a mouth-opening state all the time, and medical care personnel need to accompany and attend to the side of the mouth-opening state all the time to absorb saliva, so that the lesion area is prevented from being soaked by the saliva. The excessively cumbersome application of drugs results in a particularly limited spread of the new and useful therapeutic modality photodynamic therapy in oral specialties.
At present, most of oral mucosa lesion local medicines are applied by smearing or wet compress, most of the medicines are hydrophilic, and due to the existence of saliva in the oral cavity, the medicines are easy to dilute and even completely washed away, so that the exertion of the medicine effect is very influenced.
Some of the oral drug patches currently on the market are roughly classified into two types: the other is to make the locally applied medicine into hydrophilic patch, and attach the hydrophilic patch to the lesion area by utilizing the biological adhesion performance, so as to improve the directional positioning release of the medicine, but the patch has small area, can not be applied to the larger lesion, and can still not avoid the embarrassment of being washed away by saliva. The other is that a hydrophobic layer is arranged on the surface of the medicine layer, so that the medicine dilution by saliva is reduced while the positioning and directional release is improved. However, this patch is also not applicable to a large area lesion, and since the patch adheres to a mucous membrane by means of bio-adhesion, the adhesive ability is limited, the adhesion time is not long, and it is not applicable to long-term drug fixation. Therefore, the current oral drug patch is very limited in oral clinical application and has a relatively common effect. In addition, not all the medicines can be made into a patch form, and the components of the patch medicines are often single, so that the clinical complex medication requirements cannot be met. Therefore, it is important to study how the medicine should be fixed and prevent the saliva from washing and diluting.
