Pressure self-adapting light leakage preventing intelligent health ring

Abstract

The invention discloses a pressure self-adaptive light leakage preventing intelligent health ring, which comprises an upper shell, wherein the upper shell is provided with a first arc-shaped concave cavity; a lower shell, wherein the lower shell is movably connected with the upper shell, the lower shell is provided with a second arc-shaped concave cavity corresponding to the first arc-shaped concave cavity, a platform is arranged in the second arc-shaped concave cavity, and a detector is embedded in the upper surface of the platform; hollow silica gel, wherein the hollow silica gel is arrangedin the first arc-shaped concave cavity, the hollow silica gel is provided with a cavity which is open at the upper end, a light source corresponding to the detector is embedded in the lower surface of the cavity, and four side walls of the cavity are suspended in the first arc-shaped concave cavity. By using a special design of the structure, the coating of a probe to the finger is tighter, the light leakage is greatly reduced, and the pressure on different finger sizes is kept balanced, so that the finger end optical parameters can be stably measured at the most ideal pressure condition.

Description

technical field [0001] The invention relates to the technical field of blood pressure measurement, and more specifically, the invention relates to a pressure-adaptive light-leakage-proof intelligent health ring. Background technique [0002] The smart health ring designed by the present invention, its basic principle is to decode the waveform information by measuring the photoelectric volume wave (PPG) signal penetrating the finger, the basic working principle and the detection process of the smart health ring are the same as the inventor's two 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 he...

Problems solved by technology

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

[0009] At the same time, the ring-designed probes on the market do not take into account the problem of different pressures for different users

[0010] 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 material of the probe 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
