A smart personal portable blood pressure measuring system comprises a smart blood pressure measuring base, and a portable blood pressure measuring apparatus comprising a metal electrode detecting unit for detecting an electrocardiography (EKG) signal, a photoplethysmography detector for detecting a photoplethysmography (PPG) signal, a storage unit, a first central processor, a first power supply, and a first coupling interface unit. The storage unit stores a plurality of blood pressure values and a blood pressure algorithm. The first central processor performs a calculation according to the EKG signal, the PPG signal and the blood pressure algorithm. The first power supply provides the necessary power for operating the portable blood pressure measuring apparatus. The first coupling interface unit is coupled to the smart blood pressure measuring base so that the smart blood pressure measuring base is capable of transmitting data to the portable blood pressure measuring apparatus.

A blood pressure measurement cuff is worn on a measurement site that extends in longitudinal direction in substantial round bar shape and gradually becomes thinner from one side to another side in longitudinal direction. A band-shaped body is included which is configured to contain an air bladder between an inner cloth that is to come into contact with the measurement site and an outer cloth that opposes the inner cloth, the band-shaped body being configured to be wrapped in a circumferential direction around the measurement site. A plate member is included which is provided between the outer cloth and the air bladder in a thickness direction and in a region that corresponds to at least a portion in the circumferential direction of the band-shaped body. The thickness of the plate member gradually becomes thinner from the one side to the other side in the longitudinal direction.

A wearable blood pressure meter includes a cuff, a tactile sensor, a cuff actuator, and a controller. The cuff is sized and shaped to wear around a body part having an artery. The tactile sensor is disposed on or adjacent to an inward facing surface of the cuff. The tactile sensor is positioned along the inward facing surface to align with the artery and to measure pressure applied to the tactile sensor by the artery when the cuff is worn around the body part. The cuff actuator is mechanically coupled to the cuff to cinch the cuff around the body part. The controller is coupled to the tactile sensor to record pressure signals from which a blood pressure measurement may be determined.

Self-diagnosis of diseases is highly desired and very popular nowadays. The present application provides system, methodology, and the like for providing real-time detection of a medical condition.

A blood pressure information measurement device, including first and second fluid bags in the first fluid bag; a pressure mechanism increases/decreases pressure in an internal space of the first fluid bag and the pressure in the internal space of the second bag; a control unit controls operation of the pressure mechanism; a pressure detection device detects an internal pressure of the first and the second fluid bag; and a calculation unit that calculates blood pressure information detected by the device. In calculating blood pressure information, the control unit controls operation of the pressure increase/reduction mechanism after the internal space of one fluid bag of the first and second fluid bags pressurized and expanded until internal pressure of one fluid bag reaches a predetermined pressure, the internal space of the other fluid bag of the first and second fluid bags pressurized and expanded while the one bag is kept sealed.

An auscultatory sphygmomanometer system includes a pressure sensing and working module and a cuff. The cuff has a tube connected with the pressure sensing and working module, a gasbag connected with the tube and inflated or deflated according to the working state of the pressure sensing and working module, an audio pickup probe disposed on the gasbag and using a lateral surface of the gasbag as an oscillation membrane, and a cuff body accommodating the gasbag. While the cuff body is wound around a testee's arm, the gasbag is positioned into a first surface neighboring the testee's arm and a second surface opposite thereto and far away from the testee's arm. The connection position where the tube is joined to the gasbag is on the second surface. The sounds picked up by the audio pickup probe are sued to determine the systolic pressure and the diastolic pressure.

Example blood pressure apparatus using active materials and related methods are described herein. An example apparatus includes a band to be worn around a limb of a user, an active material carried by the band and a controller to: (1) apply an activation signal to the active material to constrict blood flow in the limb, and (2) reduce the activation signal to allow blood flow in the limb.

Methods and systems of optically measuring systolic and/or diastolic blood pressure of a mammal having biological tissue are disclosed herein. In some embodiments, the system comprises an optical blood motion sensor, a gas-sealable inflatable cushion having a flexible and transparent (FOT) barrier section, and an optical blood motion sensor comprising a laser. When pressure (e.g. at least systolic pressure) illuminates the tissue, laser light may pass en route to the tissue through the FOT sealing barrier section of the gas-sealable inflatable cushion as well as cushion interior. In some embodiments, a rigid restrictor comprising an optically transparent section is provided, and laser light also passes through the optically transparent section of the rigid restrictor en route to the biological tissue.

A blood pressure measurement method and apparatus for a wearable device are provided. The method includes: receiving, by a first wearable device, a blood pressure measurement instruction; sending, by the first wearable device, the received blood pressure measurement instruction to a second wearable device; receiving, by the first wearable device, feedback information sent by the second wearable device; starting, by the first wearable device, to collect the first blood pressure reference data; receiving, by the first wearable device, the second blood pressure reference data that is collected by the second wearable device and that is of first specified duration; and calculating, by the first wearable device, blood pressure based on the first blood pressure reference data of the first specified duration and the second blood pressure reference data of the first specified duration.

A bag-shaped structure excellent in both of creep resistance and flexibility is provided. The present invention provides a bag-shaped structure including a layer made of a thermoplastic elastomer foam. The present invention also provides a cuff for a blood pressure monitor and a blood pressure monitor each includes the bag-shaped structure.
