The utility model relates to an ear orifice dispenser based on 3D printing. The ear orifice dispenser based on 3D printing comprises a shell of the dispenser, a sealing cover and a separating net cover. Its advantages are as follows: the ear of the drug dispenser shell is provided with a guide port and a matching cap, which makes it easy to place the replaceable powder into the cavity and has good sealing performance; the end of the ear canal of the drug dispenser shell is opposite to the tympanic membrane by opening a circular stomata, and the surface is covered with a drug-separating mesh to release the drug gas; the drug dispenser shell is formed by 3D printing technology, so that it can be integrated with different patients. Different forms of external auditory canal fit perfectly; 3-D printing personalized customization provides patients with a modern improved therapeutic device, which can fully contact and fix the auricle and ear canal, avoid traction damage to the ear canal, ensure the safety of treatment, while avoiding the patients'pain and discomfort when wearing or after long-term wearing, so as to achieve the goal of continuous treatment, thereby improving the therapeutic effect. The utility model has the advantages of convenient use, non-invasive, non-toxic and side effects.

一种基于3D打印的耳窍给药器
本技术涉及医疗用品
,具体地说,是一种基于3D打印的耳窍给药器。
技术介绍
孔窍外治法作为中医非口服用药治疗疾病的特殊治疗方法,有着悠久历史。古代医籍中就可发现耳窍给药法的记载,如清代医师吴师机在外治法专著《理瀹骈文》中提到以聪耳锭、通耳锭、远志磁石锭等塞耳治疗耳聋耳鸣。为拓宽治疗手段,现代临床上,医生也可继承创新,通过改良后耳窍给药法,经辨证论治后以中药芳香开窍之品刺激耳脉,通调气血,疏导经络,耳窍得养则有效治疗耳鸣耳聋等病。由于目前标准化生产线制作的给药器无法完全适合不同患者的耳道形态和构造,可能造成部分患者佩戴后掉落或长时间佩戴后胀痛等不适情况影响疗效。而目前临床上耳鸣耳聋患者为排查听神经瘤等病,常需行耳部CT、MRI等影像检查。中国专利文献:CN201510007297.9,申请日2015.01.08,专利名称为:一种耳道给药器。公开了一种耳道给药器,包括耳道插入管和给药器,所述耳道插入管的外端设有固定装置,所述的固定装置与耳廓相配合,所述的耳道插入管的内壁上设有内螺纹,耳道插入管内设有给药管,所述的给药管的主体为套管,所述的套管的外壁上设有外螺纹,耳道插入管和套管通过内螺纹和外螺纹相配合,所述的套管的前端连接有硅胶管,所述的套管的后端连接接药口,所述的给药器连接有超声波雾化器,所述的超声波雾化器的另一端设有出雾口,所述的出雾口与接药口相连接;所述的硅胶管的截面积小于套管的截面积;所述的硅胶管上设有透气孔。中国专利文献:CN201520499728.3,申请日2015.07.09,专利名称为:一种临床用耳道用药管 ...
