  • Publication number: 20190090757
    Abstract: A method for estimating a cardiovascular characteristic parameter comprises steps of: obtaining a first action amount of a subject and a sensing signal of a cardiovascular aspect within a first time interval, wherein the first action amount is located within a first action amount threshold range; determining, based on the first action amount threshold range, a first estimation scope for estimating the cardiovascular characteristic parameter; and determining an estimation value of the cardiovascular characteristic parameter based on the above steps. The present disclosure estimates a cardiovascular characteristic parameter mainly based on a sensing signal, an action amount, an action amount threshold range, and a corresponding estimation scope. The action amount and the corresponding estimation scope reduces a certain computation capacity of corresponding exemplary apparatus, such as PPG sensor or ECG sensor, smart wristband, or smart watch.

  • Publication number: 20190090759
    Abstract: A pulse wave detecting device includes a sensor section and a control unit. The sensor section is rotatable about a first axis and is rotatable about a second axis. The control unit determines a rotation angle about the second axis and a rotation angle about the first axis in a state where the sensor section is pressed against the body surface with a prescribed pressing force. After determining the optimal roll angle and the optimal pitch angle, the control unit reduces the pressing force to a reset value smaller than the prescribed pressing force and larger than zero, increases the pressing force from this state, detects a pulse wave based on pressure signals detected by pressure detecting elements during the increase, and calculates vital information based on the detected pulse wave.

  • Publication number: 20190090760
    Abstract: A system for non-invasively determining an indication of an individual's blood pressure is described. In certain embodiments, the system calculates pulse wave transit time using two acoustic sensors. The system can include a first acoustic sensor configured to monitor heart sounds of the patient corresponding to ventricular systole and diastole and a second acoustic sensor configured to monitor arterial pulse sounds at an arterial location remote from the heart. The system can advantageously calculate a arterial pulse wave transit time (PWTT) that does not include the pre-ejection period time delay. In certain embodiments, the system further includes a processor that calculates the arterial PWTT obtained from the acoustic sensors. The system can use this arterial PWTT to determine whether to trigger an occlusive cuff measurement.

  • Publication number: 20190090764
    Abstract: A user configurable variable mode pulse indicator provides a user the ability to influence outputs indicative of a pulse occurrence at least during distortion, or high-noise events. For example, when configured to provide or trigger pulse indication outputs, a pulse indicator designates the occurrence of each pulse in a pulse oximeter-derived photo-plethysmograph waveform, through waveform analysis or some statistical measure of the pulse rate, such as an averaged pulse rate. When the configured to block outputs or not trigger pulse indication outputs, a pulse indicator disables the output for one or more of an audio or visual pulse occurrence indication. The outputs can be used to initiate an audible tone “beep” or a visual pulse indication on a display, such as a vertical spike on a horizontal trace or a corresponding indication on a bar display. The amplitude output is used to indicate data integrity and corresponding confidence in the computed values of saturation and pulse rate.

This array may emit any of the possible combinations and permutations from the domains of (but not limited to), wave frequency, intensity, color, coherence, phase and type including sinusoidal, square, or saw tooth waves. By driving these possible combinations, different areas of the brain can be stimulated. Since various areas of the brain control CNS (Central Nervous System) functions, the secondary CNS monitoring component can be coupled with these various brain regions to enhance response to training. The data that the device detectors collect will provide recommendations for natural and pharmaceutical agents to enhance the function of the device.

    Abstract: A sensor implanted in tissues and including a sensing layer is fabricated by mixing the signal transduction enzyme with non-reactive components including buffer salts and fillers, and spin coating the enzyme onto a substrate. The signal transduction enzyme is crosslinked by introducing the coated substrate in a vacuum chamber. In the chamber, a crosslinker evaporates and is deposited onto the enzyme, therefore crosslinking the enzyme.

  • Publication number: 20190090797
    Abstract: A sensor implanted in tissues and including a sensing enzyme takes an electrical measurement and compares it to reference curves for the voltage current relationship. The sensor determines whether molecular compounds are present which interfere with the detection of the molecule of interest. If interfering species are found, the measurement voltage is set in a low range to reduce errors, while if the interfering species are not found, the measurement voltage is set in a high range to increase the detected signal.

  • Publication number: 20190090798
    Abstract: A medical device useful for collecting samples of a bodily fluid, typically a vascular fluid such as blood. The subject device can also be used for infusing liquids into a patient. The fluid flow path desirably includes a forwardly projecting, rearwardly biased needle, a needle holder and a length of plastic tubing, the forwardly extending end of which is configured to function as a fluid seal to reduce the likelihood of fluid leakage during or after use. Following use, the needle is retractable from the patient by sliding a needle retraction cavity transversely into longitudinal alignment with the needle, thereby disrupting the fluid flow path and propelling the needle rearwardly so that it no longer projects from the device.

    Abstract: A modeling method for screening surgical patients, used in analysis modeling for heart rate variability (HRV). Low-cost, portable and wearable signal acquisition equipment is utilized to acquire an electrocardiography (ECG) signal of an epileptic 24 hours before surgery; a multiscale entropy (MSE) of the ECG is calculated by means of a programmed HRV analysis method, wherein characteristic parameters representing heart rate complexity are extracted on the basis of an MSE curve, and a medical refractory epileptic suitable for vagus nerve stimulation (VNS) surgery is accurately and efficiently screened, thus avoiding unnecessary expenditures and avoiding delaying an optimal opportunity for treatment. Meanwhile, the curative effects of the VNS treatment may be wholly improved by means of clearly selecting VNS surgical indication patients according to the characteristic parameters of the MSE complexity of the ECG.
