Abstract

The invention relates to the field of medical instrument, in particular to a visual acoustic immitance tester. The visual acoustic immitance tester comprises data analysis equipment, an air pump, a loudspeaker, a probe and a soft earplug, wherein the probe and the data analysis equipment are connected; the outer part of the probe is sheathed with the soft earplug; the probe is provided with threethrough holes and channels corresponding to the three through holes; and the three through holes are respectively connected with the air pump, the loudspeaker and acoustic measuring equipment. The visual acoustic immitance tester is characterized in that the rear end of the probe is provided with an optical fiber through hole, the front end thereof is provided with an endoscopic lens which is connected with an external light source by optical fiber; and the endoscopic lens is provided with the three through holes which respectively correspond to the three channels in the probe. The visual acoustic immitance tester can effectively improve the diagnosis accuracy and operation success ratio and has obvious advantages of convenient operation, reliable work and high safety and the like.

Description

Technical field: [0001] The invention relates to the field of medical instruments, in particular to a visual acoustic impedance tester. Background technique: [0002] As we all know, the middle ear is an air-filled cavity (the tympanic cavity) that is connected to the throat by a small tube, the Eustachian tube, which communicates with the atmosphere from there. accumulation. A healthy Eustachian tube is usually closed and only opens when swallowing. In the middle ear cavity, there is a structure composed of three small bones - malleus, incus and pedal bone. This structure is called the auditory ossicle chain, which connects the tympanic membrane to another membrane, the oval window. Between the chain of ossicles and the wall of the middle ear is a tendon that connects the pectoris to a small muscle, the pectoralis. The malleus is also innervated by a muscle, the tensor tympani. If either of these two muscles contracts, the eardrum will be tensed and the impedance of the...
