Problems solved by technology

The advantage of this method is that it can obtain comprehensive physiological and pathological information of sleep-disordered breathing. The disadvantage is that the equipment is huge and complicated, and it is not suitable for portable applications. Typical products such as the Sandman sleep breathing monitor produced by Tyco in the United States have 64 devices in total. Sensing signal channel, the purpose of the present invention is to provide a new technical solution, which has the advantage of being able to obtain the characteristic pathological information of patients with sleep apnea in a simple manner, and provide a feasible method for preliminary screening and general investigation of sleep apnea syndrome. technical means

Abstract

The invention discloses a sleep apnea monitoring device which comprises a respiration sensor, a voltage signal amplifier, a rectifying circuit, a time discriminating circuit and a pulse generator. Compared with the prior art, a measuring system can be simplified, the volume and the weight of the monitoring device can be reduced, an easily operated portable device is provided for diagnosing and treating sleep-related breathing disorder, the sleep apnea monitoring device obtains characteristic pathological information of sleep apnea syndrome (SAS) in a simple way and provides an effective technical means for primary screening, general survey and monitoring of SAS.

Description

technical field [0001] The invention belongs to medical monitoring technology, in particular to a device for monitoring sleep apnea. Background technique [0002] According to the diagnostic criteria generally adopted by the international medical community, one of the important criteria of sleep apnea syndrome (SAS) is the number of breathing interruptions of more than 10 seconds during 8 hours of sleep. At present, polysomnography (Polysomnograhy, PSG) is generally used to obtain such pathological information (Carskadon M, Dement WC. Normal human sleep: an overview. In: Kryger M, Roth T, Dement W, et al. Principles and practice of sleep medicine. Philadelphia: WB Saunders, 1994, 3-15). The advantage of this method is that it can obtain comprehensive physiological and pathological information of sleep-disordered breathing. The disadvantage is that the equipment is huge and complicated, and it is not suitable for portable applications. Typical products such as the Sandman sl...
