Problems solved by technology

However, these drugs are expensive and inconvenient to use, so it is difficult to promote their use in our country
Domestic scholars use urea, egg skin, and Chinese herbal medicine to treat tympanic membrane perforation. Because there is no control group, there is no experimental research, and the scientific quality is poor.

Embodiment Construction

[0013] In order to understand the present invention more clearly, the present invention will be described in further detail below through specific examples given by the inventor. 4.1 Ingredients of the film:

[0014] Seabuckthorn is sour, astringent, and warm in nature, and is often used for relieving cough and eliminating phlegm, promoting digestion and dissolving stagnation, promoting blood circulation and removing blood stasis. Analysis of its composition found that: it is rich in vitamins, amino acids, flavonoids and trace elements. β-carotene is the precursor of vitamin A, which can promote the growth of epithelial tissue, maintain the function of epithelial tissue, and participate in the synthesis of interstitial mucopolysaccharides. The content of β-carotene in seabuckthorn oil is 3 times higher than that of carrot. Vitamin C can promote wound healing and participate in collagen synthesis. The content of vitamin C in seabuckthorn is 35 times higher than that in citrus...

Abstract

The present invention discloses a slowly-released medicine membrane for curing perforation of tympanic membrane. It is made of hippophae rhmnoides oil, chitinamine and bletilla tuber through a certain preparation process. It can be used for curing various perforations of tympanic membrane, and can promote benign union of perforation of tympanic membrane instead of operative treatment, and its cost is low.

Description

[0001] 1. Field [0002] The invention belongs to the category of medicine, and relates to a medicine film, in particular to a slow-release medicine film for treating perforation of the tympanic membrane. 2. Background technology [0003] Tympanic membrane perforation is a common and frequently-occurring disease in otolaryngology, which often leads to tinnitus, ear fullness, and hearing loss in patients, and is one of the main causes of deafness. Tympanic membrane perforation is one of the main causes of deafness, and active and effective treatment measures are of great significance in the work of preventing and treating deafness. Conventional treatment is anti-infection, waiting for self-healing. Usually, some tympanic membrane perforations can heal by themselves, but most tympanic membrane perforations form scars or seal the perforation with a thin epithelial layer and affect hearing. 1-3 months before the perforation has not healed, the tympanic membrane can be repaired. ...
