High-safety auditory meatus administration device for ear-nose-throat nursing

Abstract

The invention discloses a high-safety auditory meatus administration device for ear-nose-throat nursing, and particularly relates to the field of medical instruments, the high-safety auditory meatus administration device comprises an administration tube, a protective end is detachably and movably arranged at the top end of the administration tube, a push rod is movably arranged in the administration tube, and the administration tube comprises a main tube. According to the drug delivery device, the drug delivery pipe and the protective end are used in cooperation, drugs in the material storage cavity are squeezed through the material pushing piston, the drugs are discharged out of the material storage cavity through the first material distribution holes and the second material distribution holes at different heights under the action of pressure change, the drugs are subjected to drug delivery operation in a tiny water drop shape, and the drug delivery efficiency is improved. The phenomenon that the medicine forms a film due to the fact that the medicine rapidly flows out of one opening when the medicine is administrated in a traditional mode is effectively avoided, so that it is guaranteed that the medicine is administrated to the affected part in place, the treatment effect is guaranteed, then the medicine administration pipe is rotated, the extruded medicine is evenly smeared through the protection cushion cover and the protection strip, and it is guaranteed that the good treatment effect can be obtained after external auditory canals are smeared with the medicine.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, the invention relates to a high-safety ear canal drug delivery device for ear, nose and throat care. Background technique [0002] The structure of the ear can be divided into three parts: the outer ear, middle ear and inner ear. Three parts of the human ear have different physiological roles in the transmission of sound from the natural environment to the human brain; the outer ear refers to the part of the ear that can be seen from the outside of the body, namely the pinna and the external auditory canal. The middle ear consists of the tympanic membrane, the middle ear cavity, and the ossicular chain. The inner ear is located within the petrous portion of the temporal bone and includes the semicircular canals, vestibule, and cochlea. The semicircular canals sense movement in all directions and play a role in regulating body balance. The cochlea is a snail-like ...

AI Technical Summary

Problems solved by technology

In recent years, many literatures have reported that local application of anti-allergic ointment, anti-infection ointment and fungal ointment to the external auditory canal can achieve better therapeutic effects. Inadequate coating, poor compliance of patients, etc., especially for the administration of ear canal, ointment or solution type fluid drugs are often used, and the drug film is often formed rapidly in the ear canal during the administration process, which will affect the drug. It is smoothly supplied to the affected part of the ear canal, which makes the patient's treatment effect poor and protracted. Because the ear canal is in the shape of a hole with a small diameter, even if it is applied with auxiliary equipment such as cotton swabs, it still cannot smoothly solve the problem of drug film formation. In some cases, it is impossible to accurately apply medicine to the external auditory canal to obtain good curative effect
