ABSTRACT:
An oximeter sensor formed with a housing made of a relatively rigid material into which the oximeter electrical components can be mounted is provided. An overmolded material, of lesser rigidity, is injection-molded over the housing to complete the sensor. In one embodiment the housing is made of plastic, such as polypropylene, and the overmolded material is an injection-molded thermal plastic elastomer, such as Santoprene.TM. (polypropylene with 1 micron size particles of rubber). The housing preferably contains thin portions connecting thicker portions which support the electrical and optical components. These thin portions provide natural bending portions in the final oximeter sensor. By having the thin portions near or at the central, neutral axis of the sensor, flexibility is optimized in the longitudinal direction, while the housing provides stiffness laterally.
