Abstract
Embodiments of the present concept are directed to medical devices having features that prevent contaminants from infiltrating the housing of the device while providing a mechanism to provide clear auditory sounds to aid a rescuer in providing care to a patient. In one example, a medical device includes a housing having a transmission area associated with an enclosed voice coil. An exterior diaphragm formed integrally with the housing surrounds the transmission area and provides a watertight seal of the transmission area. In addition, the diaphragm is structured to generate a sound that can be heard by the rescuer from the voice coil.
Claims13
A medical device for use by a rescuer who is caring for a patient, comprising:
- a substantially rigid housing having a transmission area;
- a component located within the housing for one of detecting a parameter of the patient and delivering therapy to the patient for caring for the patient;
- a voice coil located within the housing and positioned substantially adjacent to the transmission area in the housing, the voice coil for receiving an electrical audio signal and for generating a preliminary sound signal in response to the audio signal;
- and
- a diaphragm disposed in the housing at the transmission area to provide a watertight seal of the transmission area, the diaphragm integrally formed as a portion of the housing that surrounds the transmission area, and the diaphragm structured to generate in response to the preliminary sound signal a rescuer sound that can be heard directly by the rescuer.
