Systems and methods for non-contact multiparameter vital signs monitoring, apnea therapy, apnea diagnosis, and snore therapy

Abstract

Aspects of the of the disclosure relate to a non-contact physiological motion sensor and a monitor device that can incorporate use of the Doppler effect. A continuous wave of electromagnetic radiation can be transmitted toward one or more subjects and the Doppler-shifted received signals can be digitized and / or processed subsequently to extract information related to the cardiopulmonary motion in the one or more subjects. The extracted information can be used, for example, to determine apneic events and / or snoring events and / or to provide apnea or snoring therapy to subjects when used in conjunction with an apnea or snoring therapy device. In addition, methods of use are disclosed for sway cancellation, realization of cessation of breath, integration with multi-parameter patient monitoring systems, providing positive providing patient identification, or any combination thereof.

AI Technical Summary

Benefits of technology

The patent describes a system for treating sleep apnea that includes a wireless sleep monitor. The monitor can detect apneic events and stimulate a therapeutic device to restore the upper airway passage. The system uses electromagnetic radiation to extract information related to cardiopulmonary motion and can communicate with a therapeutic device to perform related actions. The technical effect of the system is to provide a non-invasive, effective treatment for sleep apnea.

Problems solved by technology

Unfortunately, such physiologic activity often occurs in the presence of various other motions, such as, for example, rolling over while sleeping, etc.

Thus, data from such motion sensors can typically include desired components corresponding to the physiological activity being measured, and undesired components corresponding to other motions, noise, etc.

Some existing systems do not adequately separate the desired components from the undesired components.
