    Abstract: A finger probe 10 for use with an oximeter includes an upper housing 20 and a lower housing 22 pivotably hinged together at their distal ends 12 such that a human finger can be inserted into the proximal end 14 of the finger probe into a chamber 26 formed therebetween. The probe 10 contains at least one light emitter 50 and at least one light detector 38 situated within the upper and lower housings so as to allow light from the emitter 50 to pass through the finger to the detector 38. At least one emitter 50 is contained within an emitter housing 42 that is pivotably mounted to the upper housing 20 such that it conforms to the shape of the patient's finger when inserted into the chamber 26. Also, wiring 16 for the emitter 50 and detector 38 depends outwardly from the proximal end 14 of the finger probe along the finger such that the wiring can be readily taped to the finger and, thus, help retain the finger probe 10 in position on the finger.

    Abstract: An optical fiber transducer system with energy generating means for transmitting pulsing energy at various frequencies to bi-directional couplers for each frequency. The couplers record the intensity and further transmit the pulsing energy to a wavelength multiplexer/demultiplexer. The wavelength multiplexer/demultiplexer combines the plurality of energy supply means into a single output for an optic fiber which includes an optical delay sufficient to time separate the pulsing waves of energy. Reflected energy is transmitted back through the same wavelength multiplexer/demultiplexer, bi-directional coupler so that the recorded intensity of transmission and reflectance are comparable without system influence. A method is also shown for use of an optical fiber system including the components set forth and the system requires the generation and combination of the various frequencies of energy in a multiplexer/demultiplexer, the delay for time separation and the detection in a bi-directional coupler of transmitted and reflected energy.

    Abstract: In accordance with the principles for transcutaneous measurement of a blood parameter, such as the partial pressure of a blood gas, an electrochemical measuring electrode device (1) is applied to the skin surface (2) of a person. The electrode device comprises a body (10), e.g. a thick film substrate, which is thermostated to a predetermined temperature and, furthermore, includes sensor means (11) together with a membrane (14) confining an electrolyte solution within an electrolyte reservoir (15). Furthermore, the electrode device includes a jacket comprising an annular metallic body (16), a metallic body (4) and a thick film substrate (8) which is thermostated to the same temperature as the body (10) of the electrode device. When the body is brought into contact with the skin surface, an annular surface part of the jacket is also brought into contact with the skin surface so that a virtual heating jacket is established in the skin beneath the annular surface part so as to substantially direct all heat flow from the body to tissue directly beneath the skin surface. By measuring the power supplied for thermostating the body to the predetermined temperature, the local capillary blood flow in the tissue (2) beneath the skin is measured, and the blood parameter in question is measured by means of the sensor means (11). In an alternative operational mode, the electrode device is adapted to measure deep body temperature by thermostating the jacket to a temperature so that the temperature registered by a temperature sensor of the body and the temperature registered by a temperature sensor of the jacket are identical to one another and, consequently, identical to the deep body temperature.

    Abstract: @ A pulse oximeter is disclosed of the type wherein light of two different wavelengths is passed through human or animal body tissue, such as a finger, an ear, the nasal septum or the scalp, so as to be modulated by the pulsatile component of arterial blood therein, and thereby allowing indication of oxygen saturation. The level of incident light is continually adjusted for optimal detection of the pulsatile component, while permitting accommodation to variable attenuations due to skin color, flesh thickness and other invariants. At significant slope reversal of the pulsatile component to negative (indicating a wave maximum), wave form analysis of blood flow occurs. A quotient of the pulsatile component of light transmission over the constant component of light transmission is measured for each of two wave lengths by direct digital tracking. The respective quotients are thereafter converted to a ratio, which ratio may be thereafter fitted to a curve of independently derived of oxygen saturation. Calibration is disclosed by solving four unknowns at at least four differing saturations. An output of pulse rate, pulse flow and oxygen saturation is given. An incident light source duty cycle is chosen to be at least 1 in 4 so that noise, inevitably present in the signal, may be substantially eliminated and filtered. Provision is made for a local battery-driven low power consumption instrument capable of being substantially independent of ambient light noise.

    Abstract: Apparatus for the physiological examination of tissue, particularly the human female breast, comprises a test instrument (10) having a first component (24) providing a light source, for example the termination of an optical fibre bundle (44), and a second component (26) having a light detector (58, 60, 62, 64), the two components being carried by support means (27, 28, 29) for movement towards and away from one another with means for measuring the light path length between the source and detector. The first component also carries a light detector (48) close to the light source. The apparatus is adjusted so that the two components engage opposite surfaces of the breast and bursts of light of selected wavelengths are delivered by the light source and the light transmitted through the breast is detected and signals passed to analysing apparatus (22). The apparatus may be used to produce comparisons between different readings, for example between readings from the two breasts of one woman, between readings from the same breast at separated time intervals and between readings from different women.
