A blood pressure monitor cuff is formed by stacking an outer circumferential layer arranged on a side opposite to that of a measurement site and a fluid bladder arranged on the measurement site side. The outer circumferential layer and the fluid bladder are formed of an elastomer material. Two edge portions in a lengthwise direction of the outer circumferential layer protrude in a thickness direction toward the measurement site. The fluid bladder includes a base layer that opposes the outer circumferential layer and a top layer overlapping with the base layer, and the edge portions of the base layer and the top layer are welded together forming a bladder shape. Additional sheets are welded in the thickness direction to the welded edge portions of the top layer and the base layer. The fluid bladder is arranged between the two edge portions of the outer circumferential layer in the width direction.

The present disclosure provides a tourniquet, including a surrounding device, a measuring portion, and an elastic band portion connected in series, wherein the measuring portion defines an accommodating space for placing an air bag device with an elastic air bag. A radial resonant ring formed by connecting the measuring portion and the elastic band portion in series can reduce the influence of non-radial vibration, so as to improve the sensitivity and accuracy of the radial resonance of the tourniquet of the present disclosure.

An electronic device receives a first input, where an air pump inflates and pressurizes an airbag. The electronic device obtains a pressure value of the airbag in a process of controlling the air pump to inflate and pressurize the airbag. The electronic device obtains a first pressure signal, where the first pressure signal is a signal indicating that the pressure value of the airbag changes with time in a process in which the air pump starts to inflate and pressurize the airbag until the pressure value of the airbag is equal to a preset pressure value. The electronic device determines, based on the first pressure signal, tightness of wearing a wristband by a user. The electronic device corrects, based on the tightness, a blood pressure measurement value determined based on a second pressure signal, to determine a blood pressure value of the user.

A blood pressure measurement cuff is a blood pressure measurement cuff to be attached such that it wraps around a measurement site and includes: a curler that is flexible and curves so as to naturally conform to the measurement site; an air bladder containing the curler due to being wrapped around the inner side and outer side of the curler; an inner cloth attached to an outer surface on the measurement site side of the air bladder; and an outer cloth attached to an outer surface on the side opposite to the measurement site of the air bladder.

A vital information measuring apparatus according to an aspect of the present invention is a vital information measuring apparatus for measuring vital information by compressing a measurement site of a subject with a cuff, and includes a fluid supply unit configured to supply a fluid to the cuff, and a first fluid supply controller configured to control, when a situation of the subject satisfies a first condition in which measurement of the vital information is recommended, a supply of the fluid to the cuff by the fluid supply unit to compress the measurement site in a first compression mode for informing the subject that the first condition is satisfied.

An electronic device includes a pressing component and a pressure sensor. The pressing component is disposed on a wearing structure of the electronic device. The pressing component includes an electromagnetic driving member and a pressure bearing member. The pressure sensor is disposed on the pressure bearing member, and the pressure sensor is located on a surface that is of the wearing structure and that faces a measurement body part of a user. The pressure bearing member is configured to be driven by the electromagnetic driving member to press the pressure sensor on the measurement body part, and the pressure sensor is configured to obtain a pulse wave signal of the measurement body part.

A method for manufacturing a blood pressure measurement cuff includes preparing an outer cloth, preparing an inner cloth, and forming a bag-shaped portion. The bag-shaped portion has an opening on a peripheral edge of the bag-shaped portion. A curler is inserted into the bag-shaped portion through the opening, the curler being flexible and configured to curve and conform to the measurement site. An air bladder is formed by welding the opening of the bag-shaped portion such that the air bladder surrounds an inner side and an outer side of the curler thereby containing the curler. The outer cloth is attached to an outer surface on a first side of the air bladder configured to be opposite to the measurement site, and the inner cloth is attached to an outer surface on a second side of the air bladder configured to be towards the measurement site.

The present invention provides a system for measurement of blood pressure by detecting the Korotkoff sound. The system comprises an arm band placed on the brachial artery of the user and pressure is applied to the artery by inflating the cuff through an inflation pump provided in a measurement unit, thereby forcing the artery to close. Further, the pressure is reduced by opening at least one valve and by reducing the pressure the Korotkoff sounds are detected using the ausculatory blood pressure monitoring component placed in pneumatic pathway of cuff. The acoustic sound is detected in the audible range of 20 Hz to 10 KHz and also ultrasonic range between 60 KHz to 80 Khz. In this range the signal to noise ratio is maximal. The method for detecting the blood pressure through the present system enhances acoustic signal detection that improves blood pressure measurement accuracy.

A low-profile blood pressure measurement system and methods of use are disclosed. The system includes an expandable member or structure that has a multi-compartment structure and/or is mounted on a rigid surface or structure. The system is incorporated into a portable multi-function device, or is configured to communicate with a portable multi-function device.

A system for acquiring physiological data from a patient, the system comprising: a smartphone configured for wireless communication; an adapter for releasably mounting to the smartphone; a sensor module for releasably mounting to the adapter, the sensor module comprising at least one sensor for acquiring physiological data from the patient; and a software app running on the smartphone for (i) wirelessly controlling operation of the sensor module and wirelessly receiving the physiological data from the sensor module, and (ii) wirelessly communicating with a remote location.
