The employer is a large hospital with its own laboratory, which belongs to a healthcare company.
Disability and functional restriction of the employee:
The woman has a hearing impairment and is hard of hearing. Since she is very limited in the ability to perceive acoustic information (speech and signals), she uses hearing aids to amplify them or to understand them acoustically. Acoustic information from more distant sources must be transformed so that it can be visually perceived by the woman. The GdB
(degree of disability) is 60.
The woman has been working for several years in shifts as a medical-technical laboratory assistant (MTA) in the hospital.
Workplace and work duties:
The laboratory assistant operates and monitors several analyzers in six laboratories. During the analysis process, the analyzers emit various audible signals that signal errors, disturbances and the end of the analysis. The laboratory assistant, with the help of her hearing aids, was only able to perceive the acoustic signals of the analyzers in the room in which she is located.
By using a pager system, the acoustic signals of the analyzers as well as the ring tones of the telephone and door can be sent wirelessly to the employee. For this purpose, radio transmitters are attached to the corresponding devices. These record the acoustic signal from the analyzer via a microphone and forward it to a transmitter unit, which then sends it to a small receiver. The receiver carries the laboratory assistant with him on the body. The receiving device signals the laboratory assistant by vibration and display (optically) which analyzer has given the signal.
Assistive devices used:
clocks and timepieces
environmental emergency alarm systems
