Abstract: A method and device are presented for use in non-invasive optical measurements of at least one desired characteristic of patient's blood. A condition of artificial blood kinetics is created at a measurement location in a patient's blood perfused fleshy medium and maintained for a certain time period. This condition is altered over a predetermined time interval within said certain time period so as to modulate scattering properties of blood. Optical measurements are applied to the measurement location by illuminating it with incident light beams of at least two different wavelengths in a range where the scattering properties of blood are sensitive to light radiation, detecting light responses of the medium, and generating measured data indicative of time evolutions of the light responses of the medium for said at least two different wavelengths, respectively, over at least a part of said predetermined time interval.

Abstract: The invention relates to pulse oximeters used to measure blood oxygenation. The current trend towards lower power consumption has brought a problem of erroneous readings caused by intrachannel crosstalk, i.e. errors due to the coupling of undesired capacitive, inductive, or conductive (resistive) pulse power from the emitting side of the pulse oximeter directly to the detecting side of the oximeter. The pulse oximeter of the invention is therefore provided with means for detecting whether intrachannel crosstalk is present and whether it will cause erroneous results in the oxygenation measurements. The pulse oximeter is preferably further provided with means for eliminating intrachannel crosstalk which are adapted to control the measurement so that measurement signals can be obtained which are substantially void of crosstalk components.

Abstract: A pain inferring device for designing a shape giving a subject as little pain as possible when the subject touches the shape. The pain inferring device includes an input unit, an output unit, a main control unit, a learning storage unit, and a neural network. The neural network learns the relationship between the input value of shape data and the output value of the data on the degree of pain when a subject touches a shape. By the learning, an input/output function (namely, the coefficient of coupling of neurons in layers) representing the relationship between the input and output values is defined and stored in the learning storage unit. When the shape data is inputted through the input unit, the neural network infers the degree of pain by using the function stored in the learning storage unit.

The disposable portion is disposed within the reusable portion, which includes a flow meter, a component gas concentration sensor, and a computation unit. The flow meter generates a signal as a function of the instantaneous flow volume of respiratory gases passing through the flow pathway and the component gas concentration sensor generates a signal as a function of the instantaneous fraction of a predetermined component gas in the exhaled gases.

Abstract: A method and apparatus are disclosed for using photoplethysmography to obtain physiological parameter information related to respiration or the autonomic nervous system. In one implementation, the process involves obtaining (602) a pleth, filtering (604) the pleth to remove unwanted components, identifying (606) a signal component of interest based on the filtered signal, monitoring (608) blood pressure changes, monitoring (610) heart rate, and performing (612) an analysis of the blood pressure signal to the heart rate signal to identify a phase relationship associated with the component of interest. Based on this phase relationship, the component of interest may be identified (614) as relating to the respiration or Mayer Wave. If it is related to the respiration wave (616), a respiratory parameter such as breathing rate may be determined (620). Otherwise, a Mayer Wave analysis (618) may be performed to obtain parameter information related to the autonomic nervous system.

Abstract: A patient monitoring apparatus for quantatively measuring a physiological characteristic of a patient. A first patient interface communicates with an airway of a patient such that substantially all gas inhaled and exhaled by the patient passes through the first patient interface. One or more vent elements associated with the first patient interface communicate the first patient interface with an ambient atmosphere so that a pressure differential is created between the pressure in the first patient interface and the pressure of the ambient atmosphere. A sensor communicates with the first patient interface and measures a fluid characteristic resulting from this pressure differential and outputs a first signal indicative of that characteristic. The output from the sensor is used alone, or in combination with the output from other sensors that detect other physiological characteristics, to provide a variety of information about the patient.
