Medical monitoring probe with modular device housing
First Claim
1. An electronics assembly of light emitting devices for use in a probe module, affixable to an appendage of a patient, for illuminating perfused tissue in said appendage to measure light absorption of blood analytes contained in said perfused tissue, comprising:
- a lead frame comprising a plurality of electrical conductors formed into a predetermined pattern;
light emitting means mounted on said lead frame and in electrical communication with said electrical conductors;
light reflective means mounted on said lead frame and encircling said light emitting means for directing beams of light generated by said light emitting means toward said perfused tissue; and
lens means formed prior to mating to mate with said light reflective means and mounted in mating fashion thereon for transmitting said beams of light generated by said light emitting means and reflected by said light reflective means toward said perfused tissue wherein said lens means and said light reflective means form a space therebetween.

Abstract
The manufacture of the electronics component of the probe is simplified by using an integral lead frame on which is mounted all of the passive and active elements so that the entire electronics module can be assembled independent of the housing in a simplified form prior to integration into the housing. The lead frame provides not only the electrical interconnections but the support and positioning of the various light emitting elements that comprise the electronics of the probe. The remaining segment of the manufacturing process is simplified since the workers do not have to assemble multiple diverse elements to create the device housing. The light reflecting and lens assemblies lock together and enclose an epoxy material which encapsulates the electronics elements and provides improved optical transmissivity of the generated light.
