Abstract
An optical module for coupling a fiberoptic catheter to a catheter oximeter processing apparatus. The optical module includes a plurality of light emitting diodes, each of which is mounted on a flat surface at the free end portion of a respective bracket. A plurality of optical fibers, which are adapted to be optically connected to the catheter, have their free ends secured to a mounting substrate in spaced positions and in closely spaced alignment with the diodes. The diodes are each individually provided with electrical connections that can be selectively actuated by the processing apparatus. The brackets, which are fixed at one end, are constructed of thin flexible material so that the diodes can each be adjusted generally in the plane of the receiving end faces of the optical fibers so as to obtain maximum light energy transfer therebetween.
