A mains electricity (AC-powered) device designed to provide quantitative diagnostic evaluation of a patient's reaction to thermal stimuli, typically on the skin surface, by providing information on threshold to heat or cold perception. The device typically ...
A manual instrument designed to measure a patient's sensitivity to pain (pain threshold) by applying a painful, calibrated mechanical force to the skin. It typically consists of a sharp needle, a blunt tip, and a strain gauge; the pressure needed to feel th...
An electronic instrument used to evaluate the functional condition of the middle ear by changing the air pressure in the external auditory canal to measure and graph the mobility characteristics of the tympanic membrane. It identifies abnormalities in tympa...
An electroacoustic device that generates tones throughout the audible range (usually at each octave between 125 Hz and 8 kHz) at amplitudes related to the expected thresholds for a normally hearing person, and presents them to a patient, typically one ear a...
An electroacoustic device designed to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of the sounds. The device automatic...
An electroacoustic device intended for use in a clinical setting to generate tones in the audible range to measure the hearing threshold of a patient by establishing the level at which the patient first becomes aware of the sounds. The device controls tone ...

An electromechanical transducer intended to produce the sensation of hearing by vibrating the cranial bones. It can be used as an output device with an audiometer to measure bone-conduction hearing thresholds, and thus serve as an adjunct to air-conduction ...
A battery-powered, hand-held device intended for: 1) visual examination of the outer ear canal and tympanic membrane (eardrum) by direct viewing through the ear opening; and 2) evaluation of hearing by generating tones throughout the audible range (usually ...
A mains electricity (AC-powered) ophthalmic device that provides a stimulating light source having various controlled intensities intended to measure the time required for retinal adaptation (regeneration of the visual purple) and the minimum light threshold.
An electrically-powered device designed to be used in a healthcare or assisted living setting to track the movements of an inpatient/resident for capture of high-risk behaviour (e.g., bedridden patient bed vacation attempt, fall risk) and to automatically s...
