  • Patent number: 9706933
    Abstract: In a sphygmomanometer, a value representing a perimeter of a measuring portion is obtained. A parameter for controlling a drive voltage of a pump is determined based on the value. The drive voltage is determined based on the parameter and an internal pressure of a fluid bladder to pressurize the fluid bladder. In pressurizing process, a diastolic blood pressure value is calculated. A systolic blood pressure value is estimated, and when the internal pressure of the fluid bladder reaches the pressure, the pressurizing is stopped. A gap of a valve for discharging the fluid from the fluid bladder is determined based on a perimeter of a measuring portion, and the fluid bladder is depressurized with the gap constant. In the depressurizing process, the systolic blood pressure value is calculated. When the systolic blood pressure value is calculated, the fluid is discharged from the fluid bladder, and the measurement is terminated.

  • Patent number: 9689729
    Abstract: A small and light-weight flowmeter realizes the compensation of a zero point drift. A mass flowmeter includes: a centrifugal force/centripetal force detection strain gauge adhered to a part acted upon by a centrifugal force or a centripetal force of fluid in a pipe line in which the fluid flows and a flow rate zero point drift compensation strain gauge adhered to a position different from that of the centrifugal force/centripetal force detection strain gauge. A pulse wave propagation time between the two points is used to compensate a zero point drift of a flow rate.

  • Patent number: 9610213
    Abstract: Single- or dual-bladder devices for remote ischemic preconditioning and blood pressure monitoring are disclosed along with various oscillometry-based and other methods for detecting systolic and diastolic blood pressure while the ischemic preconditioning treatment is in progress. The devices and methods of the invention provide for delivery of ischemic preconditioning at the lowest effective cuff pressure while closely monitoring patient's hemodynamics. Advantageously, the device of the invention allows both ischemic preconditioning and blood pressure monitoring to be done on the same limb. Disposable battery-powered version of the device of the present invention is especially useful for emergency use with patients suffering from acute myocardial infarction, acute stroke, or acute trauma. Additional device configurations are described for use in a percutaneous intervention and vascular sealing settings.

  • Patent number: 9532722
    Abstract: A patient monitoring system includes an inflatable cuff, a gas reservoir containing a compressed gas, and a sensor. When the inflatable cuff is coupled to a wearer, the gas reservoir supplies gas to the inflatable cuff to inflate the inflatable cuff via gas pathways. As the inflatable cuff inflates, a patient monitor can receive blood pressure data from the sensor and use the blood pressure data to determine the blood pressure of the wearer. The patient monitor can also receive blood pressure data during deflation of the inflatable cuff to determine the blood pressure of the wearer.

  • Patent number: 9526456
    Abstract: A system and method for evaluating a patient status from sampled physiometry for use in heart failure assessment is presented. Physiological measures, including at least one of direct measures regularly recorded on a substantially continuous basis by a medical device and measures derived from the direct measures are stored. At least one of those of the physiological measures, which relate to a same type of physiometry, and those of the physiological measures, which relate to a different type of physiometry are sampled. A status is determined for a patient through analysis of those sampled measures assembled from a plurality of recordation points. The sampled measures are evaluated. Trends that are indicated by the patient status, including one of a status quo and a change, which might affect cardiac performance of the patient, are identified. Each trend is compared to worsening heart failure indications to generate a notification of parameter violations.

  • Patent number: 9492094
    Abstract: In a blood pressure monitor, when a main unit is mounted on a mounting surface such as a desk, a bulging region of a first tube and a bulging region of a second tube, both located at a rear surface of the main unit, come into contact with the mounting surface. This can avoid the main unit from sliding even when the main unit is pulled by the first and second tubes. Consequently, a blood pressure monitor has a configuration in which the main unit is less likely to slide over the mounting surface even when the main unit is pulled by tubes connected to the main unit.

  • Patent number: 9474485
    Abstract: A blood pressure measurement device includes a cuff, a display, a distance sensor, an acceleration sensor, and a CPU. The display displays a positional relationship between the patient's heart and the device, which includes a flat screen. The distance sensor measures a distance between the device and the patient, and detects a subject to be measured on a line perpendicular to the flat screen of the display and measures the distance. The acceleration sensor measures an angle of inclination of the device when mounted on the patient's wrist. The CPU calculates a positional relationship between the patient's heart and the device based on the distance between the device and the subject to be measured, the angle of inclination of the device mounted on the patient's wrist, the length of the patient's forearm and upper arm, and a vertical distance between the patient's shoulder and heart.

  • Patent number: 9364156
    Abstract: A blood pressure measurement device includes a cuff, inflation/deflation unit, pressure detection unit, volume detection unit, and control unit. The control unit determines values of an arterial volume signal detected by the volume detection unit, changes a prescribed control target value from the determined value at a time of diastolic blood pressure to a vicinity of the value at the time of systolic blood pressure during a rise time, changes the prescribed control target value from the determined value at the time of systolic blood pressure to a vicinity of the value at the time of diastolic pressure during a fall time, and adjusts the pressure of the cuff by controlling the inflation/deflation unit such that the volume indicated by the arterial volume signal detected by the volume detection unit matches the prescribed control target value. Thus, by applying a control target value, blood pressure can be measured.

  • Patent number: 9332912
    Abstract: Every pulse wave, a constant volume control unit performs servo control while updating a servo gain such that a difference between an arterial volume shown by an arterial volume signal that is detected by an arterial volume detection circuit and a control target value of the servo control is less than a control deviation at which a rate of change of the arterial volume relative to a change in cuff pressure is deemed to be constant. Because the control deviation is the difference between the arterial volume shown by the arterial volume signal and the control target value, a blood pressure decision unit decides, as a blood pressure, the cuff pressure sequentially detected in a period during which servo control is performed, by correcting the cuff pressure using the control deviation and the rate of change deemed to be constant.

  • Patent number: 9173593
    Abstract: The invention provides a system for measuring respiratory rate (RR) from a patient. The system includes an impedance pneumography (IP) sensor, connected to at least two electrodes, and a processing system that receives and processes signals from the electrodes to measure an IP signal. A motion sensor (e.g. an accelerometer) measures at least one motion signal (e.g. an ACC waveform) describing movement of a portion of the patient's body to which it is attached. The processing system receives the IP and motion signals, and processes them to determine, respectfully, frequency-domain IP and motion spectra. Both spectra are then collectively processed to remove motion components from the IP spectrum and determine RR. For example, during the processing, an algorithm determines motion frequency components from the frequency-domain motion spectrum, and then using a digital filter removes these, or parameters calculated therefrom, from the IP spectrum.
