Embodiment Construction

[0059] figure 1 An embodiment of a device 1 for determining vital signs of a subject 100 is shown. The device 1 is applied to an appropriate location on the body of the subject 100 to measure physiological signals. Appropriate locations include, but are not limited to, such as figure 1 Delineated chest and thoracic region. However, it is conceivable that any part of the subject 100 is affected by said physiological phenomenon, especially the upper torso.

[0060] The device 1 for determining vital signs of a subject 100 according to one aspect of the invention enables non-invasive measurement of motion signals, eg describing breathing motion and / or motion due to cardiac beating. Said signals form the basis for determining the respiration rate and heart rate (pulse rate) of the subject. if possible from figure 1 As seen in , the device 1 can be implemented as a small device that can simply be applied to the body of the subject 100 .

Abstract

A processing device for processing physiological signals is proposed. The processing device is configured to perform the steps of: obtaining the physiological signal (6) comprising at least two wave periods (6b) originating from a physiological process; obtaining a feature describing the physiological signal (6) ( A characteristic signal (12) of the occurrence of said characteristic (P) in said physiological signal (6); determining an average waveform of said physiological signal (6) around said occurrence of said characteristic (P) in said physiological signal (6); and determining a model signal (18 ) comprising an instance of amplitude scaling of said mean waveform of said physiological signal (6) placed at said occurrence of said feature (P) in said physiological signal (6). Furthermore, a corresponding processing method, a system (1) for determining a vital sign of a subject comprising said processing device, and a computer program are proposed.

Description

technical field [0001] The present invention relates to the field of determining vital signs of a subject, and in particular to a processing device, processing method and system for processing physiological signals. Background technique [0002] A subject's vital signs are a good indicator of the subject's medical condition and health. Vital signs include, but are not limited to, respiratory rate (RR) and heart rate (HR) or beat rate. Vital signs describe underlying physiological processes such as heartbeat or respiratory movement. Ability to measure and evaluate physiological signals describing underlying physiological processes. [0003] For example, respiration monitoring can be based on different principles: measurement of respiratory effort, e.g., thoracic impedance plethysmography, respiratory induction plethysmography (often called respiration band or respiband), photoplethysmography; Measurements, eg sound recording, temperature sensing, carbon dioxide sensing. ...
