Sleep and breath preliminary screening instrument with timing power-on function and power-saving method

Abstract

The invention relates to a sleep and breath preliminary screening instrument with a timing power-on function and a power-saving method. The instrument comprises a casing wearing on the wrist, a display and control buttons are arranged on the casing, a nose airflow signal input interface and a blood oxygen signal input interface are arranged on the side wall of the casing respectively, and a control analysis circuit is fixed in the casing. According to the instrument, the timing power-on is achieved under a state that the circuit is completely out of power, cruising time of a battery is guaranteed, the power-on can be identified automatically, the effectiveness of the power-on state can be determined, and ordered carrying out of manual power-on and timing power-on can be achieved. The instrument is in a power-saving mode during storage, the working current is smaller than 30mA, the instrument can perform data storage as long as 20 hours, and the screen is in a blank screen state during the power-saving mode, so that the visual trouble caused by bright screen of the instrument during sleep of a patient can be avoided.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a sleep apnea preliminary screening instrument with the function of timing start-up and a power-saving working method. The power-on status judges the validity of the scheduled power-on, so as to achieve the orderly execution of manual power-on and timed power-on. Background technique [0002] With the acceleration of the pace of modern life and the change of lifestyle, various sleep disorders have increasingly become a prominent medical and public health problem and have attracted people's attention.

AI Technical Summary

Problems solved by technology

[0003] The current sleep detection product is mainly PSG, which has a large shape, many external leads, is inconvenient to wear, and the operation is relatively complicated. It is more suitable for severe respiratory patients to use in hospitals.

But because the early patients are not willing at all, or even think of going to the hospital for an examination, they very much hope that they can have a preliminary screening at home, but the product must be power-saving and easy to operate. Therefore, so far, there is no one that is easy to wear. , easy to operate, and suitable for ordinary people to wear at home, a sleep screening device has appeared on the market
