Method and apparatus for non-invasive blood constituent monitoring

InactiveUS6181958B1SensorsBlood characterising devicesNon invasiveHemoglobin G Szuhu
A system for determining a biologic constituent including hematocrit transcutaneously, noninvasively and continuously. A finger clip assembly includes including at least a pair of emitters and a photodiode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least one predetermined wavelength of light is passed onto or through body tissues such as a finger, earlobe, or scalp, etc. and attenuation of light at that wavelength is detected. Likewise, the change in blood flow is determined by various techniques including optical, pressure, piezo and strain gage methods. Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If an additional wavelength of light is used which attenuates light substantially differently by oxyhemoglobin and reduced hemoglobin, then the blood oxygen saturation value, independent of hematocrit may be determined. Further, if an additional wavelength of light is used which greatly attenuates light due to bilirubin (440 nm) or glucose (1060 nm), then the bilirubin or glucose value may also be determined. Also how to determine the hematocrit with a two step DC analysis technique is provided. Then a pulse wave is not required, so this method may be utilized in states of low blood pressure or low blood flow.

Medical devices for the detection, prevention and/or treatment of neurological disorders, and methods related thereto

Disclosed are devices and methods for detecting, preventing, and/or treating neurological disorders. These devices and methods utilize electrical stimulation, and comprise a unique concentric ring electrode component. The disclosed methods involve the positioning of multiple electrodes on the scalp of a mammal; monitoring the mammal's brain electrical patterns to identify the onset of a neurological event; identifying the location of the brain electrical patterns indicative of neurological event; and applying transcutaneous or transcranial electrical stimulation to the location of the neurological event to beneficially modify brain electrical patterns. The disclosed methods may be useful in the detection, prevention, and/or treatment of a variety of indications, such as epilepsy, Parkinson's Disease, Huntington's disease, Alzheimer's disease, depression, bipolar disorder, phobia, schizophrenia, multiple personality disorder, migraine or headache, concussion, attention deficit hyperactivity disorder, eating disorder, substance abuse, and anxiety. The disclosed methods may also be used in combination with other peripheral stimulation techniques.

Brain activity measurement and feedback system

A head set (2) comprises a brain electrical activity (EEG) sensing device (3) comprising EEG sensors (22) configured to be mounted on a head of a wearer so as to position the EEG sensors (22) at selected positions of interest over the wearers scalp, the EEG sensing device comprising a sensor support (4) and a flexible circuit (6) assembled to the sensor support. The sensor support and flexible circuit comprise a central stem (4a, 6a) configured to extend along a center plane of the top of the head in a direction from a nose to a centre of the back of a wearers head, a front lateral branch (4b, 6b) configured to extend across a front portion of a wearer's head extending laterally from the central stem, a center lateral branch (4c, 6c) configured to extend across a top portion of a wearer's head essentially between the wearer's ears, and a rear lateral branch (4d, 6d) configured to extend across a back portion of a wearer's head. The sensor support (4) comprises a base wall (401) and side walls (402) extending along edges of the base wall to form an essentially flat “U” shaped channel (403) in which the flexible circuit (6) is inserted and the base wall comprise EEG sensor orifices (404) to allow access to the EEG sensor contacts or electrodes on the flexible circuit.

System and method for guidance of anesthesia, analgesia and amnesia

A method for monitoring anesthetization of a patient, includes the steps of removably connecting a plurality of electrodes to the scalp of the patient and administering sufficient anesthesia to the patient so that the patient attains a plane of anesthesia selected by an operator. The brain waves of the patient are then amplified and digitized after the patient has been anesthetized, before beginning the medical procedure, to obtain a first set of digital data. The brain waves of the patient are then amplified and digitized during the medical procedure to provide a second set of digital data and the first and second sets of digital data are analyzed in at least one of a time domain and a frequency domain. Separate trajectories are then computed from the data analysis trajectories for at least two different indices of an anesthetic state of the patient during the medical procedure, the indices being selected from a group including a Depth Index (DI), a Memory Index (MI) and a Pain Index (PI). A system for providing anesthesia to a patient, includes a plurality of electrodes, a first arrangement allowing an operator to administer anesthesia to the patient until the patient has attained a selected plane of anesthesia and a second arrangement coupled to the electrodes for amplifying and digitizing brain waves of the patient after the patient has been anesthetized, before the medical procedure has been begun to obtain a first set of digital data, the second arrangement amplifying and digitizing ongoing brain waves of the patient during the medical procedure to provide a second set of digital data in combination with a third arrangement analyzing the first and second sets of digital data in at least one of a time domain and a frequency domain, a fourth arrangement computing from the data analysis separate trajectories for at least two different indices of a state of the patient during the medical procedure, the indices being selected from a group including a Depth Index (DI), a Memory Index (MI) and a Pain Index (PI), a fifth arrangement providing control signals when any of the trajectories indicates that the patient is deviating from the selected plane of anesthesia and a sixth arrangement automatically adjusting two different anesthetic agents administered to the patient based on the control signal to restore the patient to the selected plane of anesthesia.
