Finger-wearing physiological device and system

Abstract

The invention relates to a finger-wearing physiological device and system, wherein the finger-wearing physiological device includes a shell, an adjustable finger-wearing structure, a control unit, at least one light source, at least one light detector, and a vibration module. Through the adjustable finger-wearing structure, the finger-wearing physiological device is arranged on a finger of a user to obtain a blood physiological signal of the user during sleep of the user; according to the blood physiological signal, relevant information of a breathing event of the user can be obtained, and the vibration module generates vibration according to the relevant information of the breathing event, so as to generate vibration warning for the user.

Description

technical field [0001] The present invention relates to a finger-worn physiological device and system, in particular, to a finger-worn physiological device and system suitable for use during sleep and for assessing and / or improving sleep-disordered breathing. Background technique [0002] The blood physiological information obtained at the finger can be used to understand many human physiological conditions, such as blood oxygen concentration, heart rate, etc., and is commonly used in many physiological monitoring devices, such as patient monitoring, PSG, sleep apnea screening, and Many wearable form physiological health monitoring devices. [0003] The main problem in today's finger-worn optical sensing devices is how to fix them, and how to make users feel comfortable and obtain stable signal quality when worn for a long time. [0004] The most common form of probe used in existing finger-worn optical sensing devices is as follows: Figures 1A-1B The clip-on probe shown u...

Problems solved by technology

[0006] Although this design has greatly improved the shortcomings of the existing clip-on probes, there are still some areas for improvement. For example, the ring has reserved space to accommodate fingers of different thicknesses, so there is insufficient stability in the setting and it is easy to loosen. In addition, the position of the signal generating sensor and the signal receiving sensor is easy to change due to the thickness of the finger, so it is difficult to ensure that the contact between the sensor and the skin can reach the ideal state in each measurement, so there are also problems in the measurement. uncertainty

[0007] The other is a ring-type physiological information monitoring device as described in Chinese patent CN100518630C. Figure 1-11 in the text discloses that the elastic finger support belt is not only adjustable in length, but also used to set the light emitting device and the receiving device, and such a setting The hidden danger of the method is that when the length is adjusted by the support belt, it will affect the setting stability of the light-emitting device and / or the receiving device. For example, when the elastic belt body is stretched and deformed, the light-emitting / receiving device and the Contact between fingers is affected, resulting in unstable signal quality
