Drug delivery device for tympanic cavity

Abstract

The invention discloses a drug delivery device for a tympanic cavity. The drug delivery device comprises a bottom plate, four universal wheels and a drug delivery mechanism; four supporting legs are arranged at the bottom part of the bottom plate; the four universal wheels are installed at the bottom part of the four supporting legs correspondingly; a mattress is arranged at the top part of the bottom plate; and a headrest is arranged at the position, close to the end part, of the mattress. The drug delivery device further comprises a lifting system; the lifting system is fixedly arranged at the end, close to the headrest, of the bottom plate; a transverse plate is movably connected with the top part of the lifting system; a connecting rod is fixedly arranged at the bottom part of the end, away from the lifting system, of the transverse plate; and the drug delivery mechanism is hinged to the bottom of the connecting rod. The height of the drug delivery mechanism and the angle between the drug delivery mechanism and the headrest can be adjusted through the lifting system, and the connecting rod is movably connected with the drug delivery mechanism, and thus the angle between the drug delivery mechanism and the connecting rod can also be adjusted, so that the drug delivery mechanism can be fixed at the position most suitable for drug delivery, and a doctor can conveniently conduct drug delivery operation; and a fixing belt is arranged at the headrest, so that the head of a patient can be fixed, thereby improving the drug delivery efficiency.

Description

technical field [0001] The invention relates to the technical field of ear therapy attachments, in particular to a tympanic drug delivery device. Background technique [0002] Sudden deafness has become a common emergency in otology. Sudden deafness is an unexplained sensorineural hearing loss that occurs suddenly within a few minutes, hours or 3 days, and the hearing loss is 20dB or more in at least two connected frequencies. It is a common clinical condition. Otorhinolaryngology emergency, may be accompanied by tinnitus, dizziness, ear blockage, no other symptoms of cranial nerve injury. The global incidence rate is 200-300 / 100,000. In 1996, Silverstein first applied tympanic steroid infusion to treat sudden deafness. [0003] For the treatment of sudden deafness, drugs are injected into the tympanum of the ear. The existing injection of medicines into the tympanic chamber is generally through manual control of the movement of the injection mechanism relative to the tym...
