External acoustic meatus medication delivery device based on 3D (three dimensional) printing and printing method thereof

Abstract

The invention relates to an external acoustic meatus medication delivery device based on 3D (three dimensional) printing and a printing method thereof. The external acoustic meatus medication deliverydevice based on the 3D printing and the printing method thereof are characterized in that the device comprises a medication delivery device casing, a sealing cover and a medicine separation mesh cover and has the advantages that a medicine guide opening is formed in the auricle part of the medication delivery device casing; the matched sealing cover is designed; a replaceable traditional Chinesemedicine powder bag can be conveniently put into a cavity; the sealing performance is good; a round air hole is formed in a position, corresponding to the eardrum, of the tail end of the auditory meatus part of the medication delivery device casing; a layer of medicine separation mesh cover covers the surface so that medicine gas is released; the medication delivery device casing is integrally formed by a 3D printing technology, so that the perfect matching with the external auditory canals in different forms of different patients can be realized; a modern improved treatment device is providedfor a patient through the 3D printing personalized customization; the sufficient contact and fixation can be realized with the auricle and the auditory meatus; the falling during the wearing by the patient or the swelling pain uncomfortable feeling after the long-time wearing can be avoided; the continuous treatment goal is achieved, so that the treatment effect is improved; the use is convenientand fast; the noninvasive effect is achieved; no toxic or side effects exist.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a 3D printing-based ear orifice drug delivery device and a printing method thereof. Background technique [0002] As a special treatment method for treating diseases with non-oral medication in traditional Chinese medicine, external therapy through holes orifices has a long history. Records of ear orifice drug administration can be found in ancient medical books. For example, Wu Shiji, a physician in the Qing Dynasty, mentioned in the monograph "Li Yu Pian Wen" on external treatment methods that he used Cong Er Tablet, Tong Er Tablet, and Polygala Magnet Tablet to treat deafness. tinnitus. In order to broaden the treatment methods, in modern clinical practice, doctors can also inherit and innovate. Through the improvement of the ear orifice medication method, after syndrome differentiation and treatment, the aromatic and resuscitating products of traditional Chinese med...
