    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: An apparatus for measuring the concentration of blood constituents in which the architecture of the electronic processor reduces the amount of controller processing time required for tasks such as data acquisition and generation of system control signals. A demodulator is coupled to a probe for converting a first electrical signal to digital data. An interface is coupled to the demodulator for receiving the digital data and generating interrupts when a first amount of the digital data has been received. A buffer memory is coupled to the interface for storing the digital data. A controller having a controller memory (in specific embodiments, a CPU having a CPU memory) is also coupled to the buffer memory. The controller transfers the digital data from the buffer memory to the controller memory in response to the interrupts. The controller then processes the digital data to calculate the arterial oxygen concentration.

    Abstract: The present invention provides a method and apparatus for improved fetal contact with a fetal probe. The easily insertable probe includes a means for adjusting the position of the probe so that a sensor makes firm contact with the fetus. In one embodiment, the position is adjusted via a biasing segment of the probe which rotates about a fulcrum. In another embodiment, the position is adjusted via a bladder.

    Abstract: Sonde d'oxymétrie de pouls foetal (200) comportant des grappes de protubérances transmettrices de lumière (100,3 00) au-dessus de la source de lumière (110) et du détecteur de lumière (120) sur la surface de la sonde. La sonde est habituellement mise en contact avec la tête du foetus. Les grappes séparent les cheveux foetaux et pénètrent d'autres matières organiques sur la tête susceptibles d'atténuer la lumière. Les grappes transmettent ainsi un signal de lumière plus intense. Les grappes peuvent aussi être séparées par des protubérances opaques (masquant la lumière) supplémentaires (190) afin de réduire la dérivation des signaux émis.
