Embodiment Construction
[0018] like figure 1 Shown is a schematic composition diagram of the air cushion type human breathing, heartbeat and turning over automatic monitoring device system of the present invention, wherein: 1, air cushion, 2, human body, 3, bed, 4, gas conduit, 5, air pressure sensor, 6, signal conditioning circuit, 7. Microprocessor, 8. Alarm transmitting part, 9. Alarm receiving part.
[0019] figure 2 Air pressure waveforms are shown with human breathing, heartbeat and turning over.
[0020] The air pressure sensor (5) is connected to the air cushion (1) through the gas conduit (4), and the microprocessor (7) can obtain the air cushion (1) due to the breathing, heartbeat and turning over of the human body (2) through the air pressure sensor signal conditioning circuit (6). The air pressure information generated, and then use the compound filter to denoise the signal to get the following figure 2 The air pressure waveform shown, and then judge the peak and trough in the air pr...
