Psychology feels uncomfortable or even feels pressured, and can't rest in peace, and may even concern the infringement of people's privacy.

With the change of time and space, the progress of human technology and medical industry is becoming more and more mature, and there are various inventions that can replace traditional cameras to monitor whether people are resting in bed and installed inside the bed and connected to the outside of the bed. For example: The weight sensing device is installed at four corners of the bed or under the bed and combined with the wheel to connect the monitor material to the bed from the outside.

However, the foregoing invention avoids the problem that the person directly monitors the psychological discomfort caused by the person, and the above-mentioned method of using the weight sensor may cause a large error range depending on the local pressure-receiving area of the bed generated by the person lying or sitting.

More precisely, in an embodiment, the bed body 2 is composed of a plurality of airbags that are connected to each other, and a deformation phenomenon occurs when the bed body 2 itself is pressed by gravity, and the human body is placed on the lying air bed. In the case of the body 2, although the pressure deformation state of the air cushion is different due to the difference in the actual lying and sitting modes, most of the state of use will be pressed to the central section of the bed body 2, therefore, the magnetic properties of the present invention The sensor pad 1 is disposed in the buttock region 23 of the bed 2 to achieve an optimal sensing effect with a minimum of sensing elements.

As can be seen from the figure, the magnetic sensor pad 1 of the present invention is disposed under the plurality of air cells and inside the bed body 2, so that the human body does not have a foreign body sensation or feels the existence of the creation, and can be surely received.

Falling or falling on the bed 2 to avoid a psychological discomfort or stress in the patient, the person with reduced mobility, the person with a physical impairment or the elderly.

When the voltage or current generated by the magnetic sensor module 4 is greater than a specific value, it can be determined that the deformed body 3 is pressed by the weight of the human body, so that the deformation distance generated by the deformed body 3 exceeds the original expectation or The set value also causes the magnetic induction module 4 located at the upper and lower positions to be in close contact with each other, and the fluid in the deformed body 3 cannot bear the weight load of the human body. At the same time, the magnetic induction module 4 transmits information to the processor 8, The fluid output device 6 is commanded by the processor 8 to refill the fluid into the deformed body 3.

Referring to FIG. 4 to FIG. 6 , the deformed body 3 is sealed to each other by a first surface 31 and a second surface 32 , and is formed by the inner surfaces of the first surface 31 and the second surface 32 .
