Fitted type intelligent health ring with adjustable pressure

Abstract

The invention discloses a fitted type intelligent health ring with adjustable pressure. The ring comprises a ring body, a circuit board, a light source exciter and a detector. One side of the ring body is provided with an opening for adjusting the inner diameter of the ring body, the opening is provided with a connector connecting the two ends of the opening, the other side, opposite to the opening, of the ring body is provided with a rotary mechanism, the connector is provided with a distance adjustment mechanism, the ring body comprises an outer ring made from a hard material and an inner ring made from a soft material, and the inner ring and the outer ring are arranged to be fitted with each other; the circuit board is arranged at the outer side of the ring body, and is in communication connection with a measurement terminal; the light source exciter is in communication connection with the circuit board, and irradiates an internal space of the ring body; the detector is in communication connection with the circuit board, and receives a light intensity signal which is absorbed by a human body finger end and then emitted by a light source generator. According to the fitted type intelligent health ring with the adjustable pressure, through personalized settings, a finger end optical parameter can be stably measured under the most ideal pressure, and the precision of measurement of blood pressure and cardiovascular relevant parameters is improved.

Description

technical field [0001] The invention relates to the technical field of blood pressure measuring devices, and more specifically, the invention relates to a pressure-controllable integrated smart health ring. Background technique [0002] The basic principle of the intelligent health ring designed by the present invention is to decode the waveform information by measuring the photoelectric volumetric wave (PPG) signal penetrating the finger. The previous patent application documents are the same. The publication numbers of the previous patent applications are CN201620618793.8 and CN201610454021.X, and the patent name is a non-invasive continuous blood pressure measurement device. [0003] Fingertip PPG contains rich vascular health information, which can be used to calculate blood pressure and give indicators of vascular sclerosis. It is currently used in many wearable health devices. However, there are certain problems in the photoelectric continuous blood pressure measureme...

Problems solved by technology

[0006] 2. The PPG waveform will gradually change as the pressure increases. When the pressure increases to a certain level, the secondary wave will become more obvious. As the pressure increases further, the secondary wave will be gradually flattened and the waveform will begin to distort, as figure 1 shown;

For this reason, in the prior art, a mechanical setting that can adjust the inner diameter of the ring has been proposed. For example, the publication number is CN105877018, an adjustable ring, and the publication number is CN203986452, an adjustable ring, but these technical solutions are aimed at Ordinary ring, and the adjustment method is relatively rigid

[0013] At the same time, the ring-designed probes on the market do not take into account the problem of different pressures for different users

[0014] Another defect of all the above-mentioned probe designs is that the position of the probe will change slightly with the pulse of the fingertip. Because the probe material has certain elasticity, there will be instability of more than 5mmHg in the pulse cycle, making the final blood pressure measurement The accuracy is difficult to reach the internationally accepted 8mmHg standard
