    Abstract: A pulse oximeter wherein light of two different wavelengths is passed through body tissue, such as a finger, an ear or the scalp, so as to be modulated by the pulsatile component of arterial blood therein and thereby indicate oxygen saturation. A tonal signal is emitted having a pitch proportional to the ratio of oxygen saturation and a sequential repetition proportional to pulse. A visual cue consisting of an array of strobed light emitting diodes is flashed having a total light output proportional to the magnitude of the pulse and a sequential flashing rate proportional to pulse rate. A systematic rejection of extraneous or irregular detected data prevents undue sounding of alarms.

    Abstract: A fiber optic probe consisting of input and output optic fibers encased inside a small dialysis hollow tube rigidly secured inside a stainless steel needle. The dialysis tube has a reflective sealing plug element, with a dye column adjacent thereto, located between the ends of the optic fibers and the reflective plug element. The needle has two opposite slots adjacent the dye column, and the needle walls between the slots are spread outwardly or partly drilled away to provide complete exposure of the surface of the dialysis tube in this region to the surrounding tissue when the probe is inserted therein.

    Abstract: Ischemia in a hollow internal organ can be detected in its incipient stages by obtaining a CO 2 sample from within the organ of interest, measuring the partial pressure of CO 2 sample, measuring the bicarbonate concentration of an arterial blood sample, and on the basis of these two measurements calculating the pH of the wall of the organ. The value of the pH is an indicator of the onset of ischemia in the organ. The CO 2 sample is obtained by a novel catheter, multiple embodiments of which are disclosed.

    Abstract: A telemetering system for remotely measuring a physical parameter of an object such as a human or animal includes a sensor device including a tuned circuit and a sensor device coupled for altering the figure of merit of energy storage (0) of the tuned circuit in response to variations in the physical parameter, and an indicator unit for transmitting a signal to intermittently ring the tuned circuit with a burst of oscillating electromagnetic energy and sense the resultant ring signal generated by the tuned circuit. The indicator unit measures the rate of decay of the sensed ring signal after the end of each transmitted energy burst as a measure of the Q of the tuned circuit. The indicator unit includes a microprocessor which generates a measure of the rate of decay and then computes the measure of the physical parameter according to a prestored functional relationship between the physical parameter measure and the decay rate of sensed ring signal. The computed measure is then displayed in a display device. A phase locked loop circuit in the indicator unit is coupled to alter the phase and hence the frequency of the transmitted signal to be in phase with the resonant frequency of the tuned circuit. The decay rate may be measured by generating a ratio of peak voltage values sampled at two different but predefined times after the sensed ring signal begins decaying.

    Abstract: An implantable biosensor and method for sensing products, such as hydrogen peroxide, generated from an enzymatic reaction between an analyte, like glucose, and an enzyme in the presence of oxygen. The implantable biosensor is equipped with an enclosed chamber for containing oxygen and can be adapted for extracting oxygen from animal tissue adjacent the container. The reservoir of oxygen contained in the enclosed chamber is supplied to the enzymatic reaction from the side of the membrane opposite the enzyme. The enclosed chamber is designed to be impermeable to substances, like liquid and cells, that possibly can interfere with the supply of the oxygen permeating through the membrane to the enzymatic reaction. Also, the implantable biosensor is designed to optically or electrically sense products generated from the enzymatic reaction which serve as a function of the analyte.
