Abstract

The invention discloses a head-wearing drug delivery device used for treating an ear disease. The head-wearing drug delivery device is characterized by comprising a drug bag chamber positioned on the top of the head of a patient, wherein one end of the drug bag chamber is connected with a common earmuff tightly attaching to the healthy ear of the patient through a fixed-length elastic arm, the other end of the drug bag chamber is connected with a drug delivery earmuff tightly attaching to the diseased ear of the patient through a length-adjustable elastic arm, the inner side surface, facing the auricle, of the drug delivery earmuff is provided with an earplug fixed to the inlet of the auditory meatus, and the outer side surface of the drug delivery earmuff is provided with a negative pressure mechanism capable of sucking the excreta and the residual liquid drug in the auditory meatus to the earmuff; the length-adjustable elastic arm is composed of an upper section and a lower section connected through a guide groove and a telescopic mechanism, the upper section is internally provided with a hidden drug delivery pipe, and the upper end of the drug delivery pipe is communicated with a drug bag in the drug bag chamber; the lower end of the drug delivery pipe passes through a section of exposure part, enters the drug delivery earmuff, then penetrates through the earplug and reaches the tail end, close to the eardrum, of the auditory meatus; the outer side, close to the free end, of the upper section of the elastic arm is provided with a dripping-controlling valve which is connected with the drug delivery pipe in the upper section of the elastic arm, and controls the amount of the liquid drug flowing to the tail end of the auditory meatus.

Description

technical field [0001] The invention relates to a clinical treatment instrument for the departments of ear, nose and throat, in particular to a continuous drug delivery device for treating ear diseases such as otitis media or traumatic perforation of the tympanic membrane. Background technique [0002] In recent years, otitis media patients account for a large proportion of otolaryngology patients, and their symptoms are manifested as pus in the external auditory canal, itching, hearing loss, and tinnitus. In addition, there are many outpatients with traumatic tympanic membrane perforation. During the treatment process, how to keep the external auditory canal clean so that the perforated tympanic membrane is isolated from dirty air and water is particularly important for the cure of external auditory canal infection. [0003] In outpatient ear endoscopy, it was found that some elderly patients with otitis media perforation healed spontaneously, but tympanic membrane perforat...
