The present invention includes improved medical communication devices, such as nurse call cords, pillow speakers, and the like, that can be used in an oxygenated environment and that can withstand the sterilization and cleaning procedures commonly used in health care institutions. One embodiment of the present invention comprises a hermetically sealed housing and a switch. The switch is located within the hermetically sealed housing and is capable of converting an electrical input into an electrical signal. The present invention may further include a cable that communicates electrical signals to and from the communication. Another embodiment of the present invention comprises a hermetically sealed housing and a sound generator. The sound generator is located within the hermetically sealed housing and is capable of converting an electrical input into an audible sound. The present invention may also include a switch located within the hermetically sealed housing. This switch may receive a command input from a patient and relay the command to a device under control. The present invention may further include a cable that communicates electrical signals to and from the sound generator. Another aspect of the present invention is a method of making a medical communication device, one embodiment of which comprises providing a electronic communication component, such as a sound generator or a switch, attaching an electrical cable to the electronic communication component, and hermetically sealing the electronic communication component.
