Abstract

The invention discloses an immersive sleep-aiding eye mask and a self-adaptive closed-loop control method thereof in perimenopause. The control module jointly adjusts the hot compress set temperature, the audio mode/volume and the aromatherapy dosage under the safety constraint, and automatically executes the inhibition strategies such as heat stopping/heat reducing and the like when the hot flashes risk is increased, thereby reducing night awakening and improving sleeping experience.

Description

Immersion type sleep-aiding eye mask and self-adaptive closed-loop control method thereof during perimenopause Technical Field The invention relates to the technical field of healthy sleep auxiliary equipment, in particular to a multimode self-adaptive closed-loop control method for sleep disorder and hot flashes of perimenopausal people. Background The modern people generally have the problems of difficulty in falling asleep, shallow sleep, easy awakening at night and the like. Perimenopausal/climacteric women often also have physiological and psychological reactions such as night hot flashes, palpitations, anxiety, and the like, resulting in sleep fragmentation, further exacerbating fatigue and mood swings. Most of the existing sleep-aiding products are single sensory stimuli, such as a pure white noise player, a common steam eyeshade or a fragrance diffuser. The whole flow requirement of 'quick falling asleep-stable maintaining-sudden tidal fever/awakening treatment' is often difficult to simultaneously consider by single stimulus, and in the scene of a partner in the same bed, the externally-emitted sound possibly causes interference, the dosage of the aromatherapy fragrance expander is difficult to control, the problems of over-strong smell, overlong duration time or discomfort to sensitive people exist, the temperature curve of the steam eyeshade is fixed, and the safe and effective dynamic adjustment cannot be carried out according to the skin temperature, body movement and autonomic nerve state of an individual. Therefore, there is a need for an immersive relaxation sleep-aiding device and method that can combine thermal, acoustic and olfactory stimuli without interfering with partners, and can achieve adaptive adjustment according to physiological signals and behavioral signals, and has safety constraint and closed-loop feedback. Disclosure of Invention 1. Technical problem to be solved The invention aims to solve the problems that the existing sleep-aiding product is single-mode, lacks closed-loop feedback, is difficult to cope with night hot flashes and wake events during perimenopause, and is difficult to finely control the dosage and safety boundary, and the like, and provides a multi-sense immersion type relaxation sleep-aiding system in a wearable eyeshade form and a corresponding self-adaptive closed-loop control method. 2.
