Respiratory Waveform Drawing System

Abstract

A breathing waveform drawing system (100), which draws the breathing waveform of a detected object on a bed, comprising: a plurality of load detectors (11, 12, 13, 14), which are arranged on a bed (BD) or a bed leg of a bed Below, the load of the detected object is detected; the center of gravity position calculation part (31), which obtains the center of gravity position (G) of the detected object based on the load of the above-mentioned detected object; the vibration coordinate setting part (34), which uses a certain The position of the center of gravity at any time is the initial origin (TO1), and the position at which the distance between the center of gravity displaced from the initial origin and the initial origin becomes the largest, that is, the first extreme point (EP1), is obtained, and the occurrence the second extreme point (EP2), which is the position at which the distance between the position of the center of gravity displaced from the first extreme point and the above-mentioned initial origin on the side opposite to the first extreme point from the above-mentioned initial origin becomes maximum, The direction connecting the first extreme point and the second extreme point is set as the temporary vibration axis (TA2), and the midpoint between the first extreme point and the second extreme point is set as the temporary vibration origin (TO2); and a waveform drawing unit (35) that draws the respiratory waveform by representing the displacement (D) of the center of gravity projected onto the temporary vibration axis from the temporary vibration origin with respect to time.

Description

technical field [0001] The present invention relates to a respiratory waveform rendering system for rendering a respiratory waveform of a detected object based on changes in the position of the center of gravity of the detected object. Background technique [0002] The biological information of the detected object is one of the important information used to understand the physical state of the patient and the care receiver at the scene of medical treatment and nursing care. For example, grasping the breathing state of the subject can contribute to the grasping of symptoms such as sleep apnea syndrome and snoring, and the improvement of the above-mentioned symptoms. [0003] It is proposed to arrange a load sensor under a bed leg portion of a bed, and to measure a breathing state of a subject based on a measurement value of the load sensor (Patent Document 1). Furthermore, it has also been proposed to arrange load detectors under the bed legs of the bed to obtain the movemen...
