Description

Active cuff

This creation relates to a cuff, especially an active cuff that can change the frequency of inflation.

With the conventional cuff, wear the cuff on the upper arm when in use, and infuse air into the air bag to make the air compress the blood vessels in the upper arm and stop the blood flow, and then slowly relax the compression and blood in the compressed blood vessels The flow pressure is transmitted back to the cuff. At this time, the blood flow starts to flow in accordance with the heart's pulsation. In the process of pressurization and decompression, the cuff is used to reflect the vibration of the blood vessel wall when the heart beats to the change in the pressure of the cuff (Pulse wave) to determine the pressure amplitude in the cuff to determine the blood pressure value, and use the electronic stethoscope to measure the millisecond difference of the sound from the apical pulse to the radial artery and the level of audio to determine whether there is a problem with the blood vessel (such as return A slow voice means hardening of the blood vessels, and a high return tone means blood vessel blockage); however, the conventional cuff must be tied to the position of the upper arm and must rely on the frequency of the heart to perform the measurement, which cannot respond. Different measurement sites require measurement. Furthermore, because the heartbeat frequency is a fixed bass frequency, the accuracy of the detection is limited, and it is impossible to detect deeper and more specific data (such as the exact position of the blood vessel hardening). And degree, the exact position and degree of blood vessel obstruction).

Based on this, how to measure in response to the needs of different measurement sites, and accurately know the blood vessel-related data (such as: the data of the degree of vascular stiffness and the degree of vascular obstruction of each measurement site according to different measurement sites), this It is a problem to be solved.
