Abstract
The invention relates to the unrestrained sleep physiological information detection device, and aims to solve the problems that in the existing physiological information detection device, a plurality of types of electrodes or other sensors are carried by the human body, so psychological or physiological burden is caused to people to be tested during the detection, and the normal sleeping of people is influenced; and the operation is complicated, the professional staff is required to carry out operation detection, so the price is expensive. A plastic hose which is fully filled with water and has a certain softness is put between two panels, connecting bolts are adjusted to enable the plastic hose and the two panels to be right clamped, one end of the plastic hose is sealed, the other end of the plastic hose is connected with a pressure transducer, and the output of the pressure transducer is connected with a subsequent signal processing circuit, so a sensing device for sleep information detection is formed. The strength and the frequency of the water vibration which is caused by respiring, heart beating and snoring are different, so different sleep physiological information signals can be obtained through amplifying, denoising and separating the signals. The unrestrained sleep physiological information detection device is applied in the medical care field.
