Ear canal administration device for otorhinolaryngology nursing

Abstract

The invention discloses an ear canal drug administration device for otorhinolaryngology nursing. The ear canal drug administration device comprises a drug administration assembly and a protection assembly, wherein the drug administration assembly comprises a fixed cylinder, the inner wall of the fixed cylinder is movably provided with a movable block, one end of the movable block is fixedly provided with a movable rod, one end of the movable block is fixedly provided with a corrugated pipe, the corrugated pipe is fixedly arranged on the inner wall of the fixed cylinder, and a first connecting pipe is fixedly arranged on the surface of the corrugated pipe. The movable rod drives the movable block to move leftwards, and air in the fixed cylinder is injected into a rubber film through an air outlet pipe and a third connecting pipe, so that the rubber film expands to drive a porous silica gel ring to slightly expand, a hole in the middle of the side wall of the porous silica gel ring is expanded, ointment on the inner wall of the porous silica gel ring and the surface of the rubber film is extruded under the expansion of the rubber film to seep outwards from the hole in the middle of the side wall of the porous silica gel ring and is uniformly smeared in the external auditory canal of the patient, and then the purpose of uniformly smearing the ointment is fulfilled.
