Description

Bone conduction threshold test pillow

Technical Field

The utility model belongs to the field of hearing test equipment, and relates to an infant bone conduction threshold test pillow.

Background

The infant bone conduction threshold test and the conventional bone conduction threshold test have different requirements, a patient is required to be in a deep sleep state (deep sleep), the infant is required to be prepared before the test, and the infant is assisted to sleep by taking 10% chloral hydrate, which is a check mainly made for the infant with the auditory canal closed, which cannot be matched with the conventional bone conduction threshold test.

Currently, when a patient is sleeping deeply, a physician needs to place the bone conduction vibrator at the mastoid, but the position of the bone conduction vibrator may move or relax. Mastoid is one of the anatomical structures of human skull, and is a part of temporal bone of the skull, and the mastoid is called mastoid because of the cone-shaped protrusion at the back lower part of the temporal bone scale.

In order to prevent the bone conduction vibrator from being displaced, the bone conduction vibrator is generally pressed on the mastoid by a hand of a family member in clinical audiometry work. Generally, as the testing time is long, the hands of the family members of the patient can loosen, so that the bone conduction vibrators are displaced, the obtained bone conduction threshold testing result is obviously changed, the result is inaccurate, or the detection time is longer, so that the testing efficiency is reduced.

Or on the other hand, when the bone conduction oscillator is used for bone conduction threshold test, the reference pressure value is 5.4N, the family members press the bone conduction oscillator by hands, and the accuracy of the test result is influenced when the pressure is heavy and light.
