Ring-type cuff for blood pressure manometer

Abstract

The present invention relates to a ring-type cuff for blood pressure manometer, wherein the cuff (C) comprises: a circular rubber ring () wearable on a wrist or an ankle; a resilient coil spring () built-in inside the tubular rubber ring () in the range of length of the rubber ring to obtain a predetermined flexibility, to suppress excessive stretching, to strengthen durability, and to maintain resilience; and a measurement portion () comprising a pressure sensor (S) for measuring blood pressure, a transmission circuit (IC) for transmitting measurement data to the outside, a power source (v), a power switch (sw), and a pilot lamp (LED). The ring-type cuff (C) is worn on the wrist or the ankle at ordinary times; when measuring blood pressure, the ring-type cuff (C) is placed on a measurement site to be fixed by a self-elastic supporting force, blood pressure is measured by the pressure sensor (S) of the measurement portion () and the pilot lamp (LED) is simultaneously lighted, the measured data is wired and wirelessly transferred to an external sphygmomanometer by the transmission circuit (IC) to be analyzed, and the analyzed result is displayed on a display portion through a letter or a figure; and the pilot lamp is also turned off if the ring-type cuff (C) descends to the wrist after measurement.
