Abstract
A probe for use with a pulse oximeter apparatus is disclosed, as are a fixture for and a method of making the probe. The probe includes a housing and two fiber optic bundles. The first bundle has an emitter portion at one end, and is used for conducting light from a source thereof to the emitter portion from which the light is transmitted for transillumination through a body part. The second bundle is for conducting the transilluminated light incident upon a detector portion thereof to the pulse oximeter apparatus. The housing is overmolded onto the bundles so that the emitter and detector portions are securely positioned diametrically opposite each other across an opening defined by the housing. The overmolding makes the alignment of the emitter and detector portions largely impervious to movement of the body part when placed within the opening and thus between the emitter and detector portions.
