Abstract
This invention relates to a system and method for monitoring a patient. The method comprises obtaining thermal images from a thermal sensor; obtaining respiratory rate and heart rate measurement from an ultra-wideband (UWB) sensor; analysing the thermal images to determine presence of patient on a bed, temperature and activity intensity; and in response to determining presence of patient on the bed and the activity intensity is below a certain threshold, record the temperature, respiratory rate and heart rate.
Claims17
A monitoring system comprising:
- a thermal sensor configured to obtain thermal images, wherein each thermal image is a combination of pixels, and each pixel is defined based on an individual temperature reading;
- an ultra-wideband (UWB) sensor configured to obtain respiratory rate and heart rate measurement;
- and
- a processing unit comprising a processor, memory and instructions stored on the memory and executable by the processor to:
- analyse the thermal images to determine a presence of a patient on a bed, and a temperature of the patient on the bed, by normalizing the combination of pixels based on an average human body temperature and processing the normalized combination of pixels through a series of image processing techniques including at least one of:
- contrast enhancement, brightness enhancement, and sharpening of edges;
- and
- compare value changes of the combination of pixels within a predefined boundary from a first thermal image to subsequent thermal images to determine an activity intensity;
- and
- in response to determining presence of patient on the bed and the activity intensity is above a first predetermined threshold, record the temperature, respiratory rate and heart rate.
