  • Patent number: 8024021
    Abstract: To measure oxygen saturation in blood, living tissue is irradiated with a first light beam having a first wavelength and a second light beam having a second wavelength. A first electrical signal is generated from the first light beam reflected from or transmitted through the tissue. A second electrical signal is generated from the second light beam reflected from or transmitted through the tissue. The first electrical signal is divided into a plurality of first segments, each including a part of the first electrical signal for a predetermined time period. The second electrical signal is divided into a plurality of second segments, each including a part of the second electrical signal for the predetermined time period. A gradient of a regression line is calculated between every one of the first segments and an associated one of the second segments, thereby obtaining a plurality of gradients.

  • Patent number: 8021298
    Abstract: A pain depth mapping system and method may be used to map the location and depth of pain experienced by a user (e.g., a patient). The pain depth mapping system and method is capable of displaying one or more body representations with symptom representations representing the location of the pain. The pain depth mapping system and method allows the user to delineate one or more user-defined pain depth regions on a cross-section of the body representation with the symptom representations to form a pain map. The symptom mapping system and method may also allow the user to vary the pain intensity represented by the symptom representations as the user delineates the user-defined pain depth region(s).

  • Patent number: 8005523
    Abstract: A signal processing technique for estimating the frequency of a pulsatile signal (including but not limited to pulse oximetry signals) is disclosed. Each of the functions contained within a pre-selected set of functions is compared to the input signal at many different time-shifts, and the function/time-shift combination that best matches the input signal is selected. The frequency of the best-matching function is then used as the best estimate of the frequency of the input signal. Optionally, once a function has been selected, the rising portion of the selected function can be correlated in time to the rising portion of the input signal. Improved results can then be obtained by basing the oxygen saturation level calculations on samples taken from the rising portion of the input signal.

  • Patent number: 8002701
    Abstract: A medical alarm communications system comprises a pager like device to be kept near a patient. The pager like device communicates medical alerts regarding the patient to a remote central station, which can provide therapeutic and/or diagnostic assistance by communicating to the pager like device. When the pager like device determines that an alert should be sent to the central station, it attempts to establish communication with the central station according to a primary communication protocol. If this attempt is unsuccessful according to some predetermined criteria (e.g. too much time has elapsed before communication is established), then the pager like device generates a message to the patient indicative of the failure, and The attempts to establish communication with the central station according to a secondary communication protocol.

  • Patent number: 8000761
    Abstract: A pulse oximeter sensor has both a reusable and a disposable portion. The reusable portion of the sensor preserves the relatively long-lived and costly emitter, detector and connector components. The disposable portion of the sensor is the relatively inexpensive adhesive tape component that is used to secure the sensor to a measurement site, typically a patient's finger or toe. The disposable portion of the sensor is removably attached to the reusable portion in a manner that allows the disposable portion to be readily replaced when the adhesive is expended or the tape becomes soiled or excessively worn. The disposable portion may also contain an information element useful for sensor identification or for security purposes to insure patient safety.

  • Patent number: 7993267
    Abstract: A system and method for allowing a patient to access an automated process for managing a specified health problem called a disease. The system performs disease management in a fully automated manner, using periodic interactive dialogs with the patient to obtain health state measurements from the patient, to evaluate and assess the progress of the patient's disease, to review and adjust therapy to optimal levels, and to give the patient medical advice for administering treatment and handling symptom flare-ups and acute episodes of the disease. The medical records are updated, the progression of the disease is stored and tracked, and the patient's preferences for treatment are stored and then used to offer medical advice based on the current state of the disease. A prestored general disease trend curve is compared against a patient specific disease trend curve, and the system makes an automated response such as adjusting therapy.

  • Patent number: 7991447
    Abstract: To control information obtained from inside of a living body with higher precision as compared to that in the conventional technology by controlling a ratio of intensities of light, directed to a trial body, in a plurality of wavelength ranges different in peak wavelength from each other, a measurement error included in information obtained from the living body can be controlled by changing a ratio of intensity of the light in the first wavelength range against that of the light in the second wavelength range. When intensity of irradiated light is limited from the viewpoint of safety to the trial subject, keeping a ratio of the light irradiated to the trial body in the first wavelength range against that of the light in the second wavelength range under a prespecified value and also changing the ratio of irradiated light intensities under the prespecified value.

  • Patent number: 7991448
    Abstract: A method for removing motion artifacts from devices for sensing bodily parameters and apparatus and system for effecting same that includes analyzing segments of measured data representing bodily parameters and possibly noise from motion artifacts. Each data segment is frequency analyzed to determine up to three candidate peaks for further analysis. Up to three candidate frequencies may be filtered and various parameters associated with each candidate frequency are calculated. A pulse-estimate input may also be accepted from an external source. The best frequency, if one exists, is determined by arbitrating the candidate frequencies and the pulse-estimate input using the calculated parameters according to predefined criteria. If a best frequency is found, a pulse rate and SpO2 may be output. If a best frequency is not found, other, conventional techniques for calculating pulse rate and SpO2 may be used.
