FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment. A cuff contains a chamber for the application of pressure to the area of measurement; a screwable element for displacement of a chamber (161) for a flowing medium to the area of measurement, and a chamber-like covering element, which includes the chamber of the flowing medium and the screwable element and is configured in the form of a tape, wrapped around the area of measurement. The screwable element has a curved shape, which follows the direction, in which the screwable element is wrapped around the area of measurement, and has two curvilinear regions and a rectilinear connecting region, which connects the said curvilinear regions in the section in the points of bending, in which the radius of the screwable element curvature changes. The connecting region is located inside the curve, formed by the extension of the curvilinear regions. The central position between the first point of bending in the section and the second point of bending in the section is superposed on the central position of the chamber for the flowing medium in the direction, in which the chamber for the flowing medium is wrapped around the area of measurement. Versions of implementation of the device for pressure measurement and an additional version of the cuff are disclosed.
EFFECT: group of inventions makes it possible to reduce the measurement error due to the reduction of errors of the chamber volume change.
