  • Patent number: 10610239
    Abstract: A non-invasive cerebral perfusion increasing device including four cuffing pad units and a control unit which is connected to the cuffing pad units and is equipped with a blood pressure sensing module and a compression control module. In the non-invasive cerebral perfusion increasing device each cuffing pad unit respectively includes a compression pad, a compression control member and a blood pressure sensing member. The blood pressure sensing module uses the blood pressure sensing members to sense the systolic blood pressure values of the portions of each of the limbs where they are attached and the compression control module controls the degree of compression of each compression pad by controlling the compression control member to a setting desired by the user based on the sensed blood pressure value, such that the blood flow applied to the limbs is blocked and, indirectly, cerebral perfusion is increased.

  • Patent number: 10582861
    Abstract: The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

  • Patent number: 10433743
    Abstract: A method for secure physiological data acquisition and storage is provided. An identifier of a physiological monitoring device that is configured to store the identifier within a cryptographic circuit is obtained by a programming wand. A password for accessing physiological monitoring data collected using that device is generated based on at least a portion of the identifier. The password is encrypted using a secret key, and password is loaded into the cryptographic circuit. The secret key is loaded into a monitor recorder, wherein the monitor recorder retrieves the identifier and the password from the device, decodes the password, and offloads the physiological monitoring data together with the identifier and the decoded password. The identifier and the password are reported to at least one server. The offloaded physiological monitoring data is stored using the identifier. Access to the data is granted upon receipt of the decoded password from a user.

  • Patent number: 10413349
    Abstract: A surgical system and corresponding methods for identifying tissue or vessels and assessing their conditions includes a probing signal source for applying a probing signal to the tissue and a response signal monitor for monitoring a response signal that varies according to the level of blood circulation in the tissue or vessels. The response signal monitor monitors the response signal over an interval equal to or longer than an interval between two successive cardiac contractions. The surgical system includes a microprocessor that analyzes the amplitude and/or phase of the response signal to determine the level of blood circulation in the tissue or in different portions of the tissue, and determines a tissue parameter based upon the level of blood circulation. The surgical system may monitor a cardiac signal related to cardiac contractions and correlate the response signal and the cardiac signal to determine a level of blood circulation in the tissue.

    Abstract: Systems and methods for calibrating a force input device are disclosed. The force input device includes a force-sensitive structure with a number of individual force sensors that compress or expand in response to input. The force input device measures an electrical property of the force sensors of the force-sensitive structure. After the force sensors are measured, the values obtained are adjusted based on a mechanical model of the response of the force sensitive structure. Upon receiving a force input event of high magnitude, the force input device recalibrates the mechanical model.

  • Patent number: 10349841
    Abstract: A blood pressure cuff assembly for an ambulatory blood pressure monitor may include a hollow cuff and an elastic liner provided on the reverse side of the cuff. An airbag may be provided in the cuff. A first connection part and a second connection part may be provided on the cuff. A third connection part and a fourth connection part may be correspondingly provided on the liner. The effect of tight inside and loose outside is achieved by the combination of the elastic liner and the cuff. When worn on an upper arm, the elastic liner has an elastic deformation and consequently tightens around the upper arm so as to realize certain slip resistance, and the cuff will not slip down even tied a bit loosely when located on the upper arm. The feeling of constraint from the cuff is reduced significantly and the comfort is improved.

  • Patent number: 10297143
    Abstract: Provided are techniques for detecting quality of physiologic data using contact pressure data for alarm generation. First data is received that comprises physiologic data and an alarm condition. Second data is received from pressure-sensitive sensors, wherein the second data comprises contact pressure data. In response to determining that the second data indicates movement of an entity, a delay is created for generation of an alarm for the alarm condition. In response to determining that the delay has expired, it is determined whether the first data has changed to indicate that the alarm condition is resolved. In response to determining that the first data has changed to indicate that the alarm condition is resolved, the alarm condition is cleared. In response to determining that the first data has not changed to indicate that the alarm condition is resolved, the alarm is generated.
