Each media sensor 2 is disposed on the throw pillow body 1 in a multi-point manner, that is, each media sensor 2 is dispersedly distributed on the throw pillow body, and may be disposed inside the throw pillow body 1 or on the surface of the throw pillow body 1, and specifically, corresponding setting may be performed according to the sensing distance of the media sensor 2 and the thickness of the throw pillow body 1; the media sensors 2 are extremely sensitive to the limbs containing water, and can monitor the water-containing objects within a certain distance, so that when a user uses the throw pillow, the approaching limbs can be sensed by the media sensors 2, and then the coverage area of the limbs of the user on the throw pillow body 1 when the user embraces the throw pillow can be obtained through media sensing signals sensed by the media sensors 2. Each pressure sensor 3 multiple spot positions set up on embracing pillow body 1, and each pressure sensor 3 dispersion sets up on embracing pillow body 1 promptly, specifically can set up and embrace 1 surfaces of pillow body or embrace 1 insidely of pillow body, and embrace that 1 inside of pillow body is filled with flexible material, if set up inside embracing pillow body 1, then pressure sensor 3 sets up among the flexible material of embracing pillow body 1 inside. When the user uses the throw pillow, the limb of the user forms an encircling to the throw pillow body 1, so that the pressure of the limb of the user acting on the throw pillow body 1 can be sensed by the pressure sensors 3 at different positions and different directions in the throw pillow body 1. The throw pillow firstly determines the area of the area covered by the limbs of the user on the surface of the throw pillow body 1 through sensing medium signals monitored by the medium sensors 2, and then distinguishes the current trunk surface and arm surface of the throw pillow body 1 according to the area covered by the limbs of the user. Specifically, if the area of the first area covered by the limb of the user is larger than the area of the second area, the surface of the throw pillow body 1 corresponding to the area of the first area is directly opposite to the trunk of the user, the surface is marked as a trunk surface by the throw pillow, the other surface of the throw pillow body 1 corresponding to the area of the second area is marked as an arm surface, and the arm surface is directly opposite to the arm of the user. Then, the throw pillow processes the pressure signals distributed on the trunk surface by a difference method to obtain the breathing signal and the heartbeat signal of the user. Then, in order to avoid pressure interference generated during heartbeat and respiration of the user, the throw pillow selects an overall pressure signal which is distributed on the arm surface and is monitored by each pressure sensor 3 in the same respiration phase as a current throw pressure signal of the user on the throw pillow body 1.

The first breathing signal is a breathing signal of an expiration phase of a user, and the second breathing signal is a breathing signal of an inspiration phase of the user, so that the throw pillow synthesizes the first breathing signal and the second breathing signal to obtain a complete breathing signal of the user. The throw pillow divides the first breathing signal by each third pressure signal respectively to obtain a ratio between the first breathing signal and each third pressure signal, namely a first ratio. And the bolster divides the second respiratory signal by each fourth pressure signal respectively to obtain a ratio between the second respiratory signal and each fourth pressure signal, namely a second ratio. Wherein the first ratio corresponds to the third pressure signal, and the second ratio corresponds to the fourth pressure signal, for example, if the ratio between the first respiration signal and the third pressure signal a is a first ratio a, the first ratio a corresponds to the third pressure signal a; the ratio between the first breathing signal and the third pressure signal B is a first ratio B, which corresponds to the third pressure signal B. And the throw pillow respectively compares the associated first ratio and second ratio one by one according to the incidence relation between the third pressure signal and the fourth pressure signal, and screens out a group of ratios with the largest difference value between the first ratio and the second ratio as a third ratio and a fourth ratio. For example, the first ratio a corresponds to the third pressure signal a, the second ratio a corresponds to the fourth pressure signal a, and the third pressure signal a and the fourth pressure signal a are acquired by the same pressure sensor 3 at the same time and are correlated with each other. Therefore, when the ratio is screened, the first ratio A and the second ratio A are used as a group of data to calculate the difference between the first ratio A and the second ratio A, then the difference is compared with the differences of other groups, and a group of ratios with the largest difference is screened out to be used as a third ratio and a fourth ratio. And screening a fifth pressure signal corresponding to the third ratio from each third pressure signal and screening a sixth pressure signal corresponding to the fourth ratio from each fourth pressure signal according to the corresponding relation between the ratio and the pressure signals. And finally, the throw pillow obtains the heartbeat signal of the user according to the fifth pressure signal and the sixth pressure signal.

Further, the step of determining the torso surface and the arm surface of the bolster according to the distribution area of each of the media sensing signals includes:

s201: respectively calculating the sum of the areas of the distribution areas of the medium sensing signals on the same surface of the throw pillow to obtain a first distribution area and a second distribution area;

s202: judging the size relationship between the first distribution area and the second distribution area;

s203: if the first distribution area is larger than the second distribution area, marking one surface of the throw pillow corresponding to the first distribution area as the trunk surface, and marking the other surface of the throw pillow corresponding to the second distribution area as the arm surface;

s204, if the first distribution area is smaller than the second distribution area, marking one surface of the throw pillow corresponding to the first distribution area as the arm surface, and marking the other surface of the throw pillow corresponding to the second distribution area as the trunk surface.

In this embodiment, the media sensors 2 are disposed on the surfaces of the two sides of the throw pillow body 1, and the throw pillow acquires signals of the media sensors 2, which are close to the throw pillow body 1, of the user limbs through the media sensors 2. The throw pillow respectively calculates the sum of the areas of the distribution areas of the medium sensors 2 on the same surface to obtain a first distribution area and a second distribution area. Then, the throw pillow judges the size relation between the first distribution area and the second distribution area. When the user uses the throw pillow, the area of the throw pillow, which is over against the trunk of the user, is obviously larger than the area of the throw pillow, which is over against the arms of the user. Therefore, if the first distribution area is larger than the second distribution area, the throw pillow can determine that one surface of the throw pillow corresponding to the first distribution area is currently over against the trunk of the user, and automatically mark the surface as the trunk surface; and the other surface of the throw pillow corresponding to the second distribution area is marked as an arm surface, and the arm surface is opposite to the arm of the user. If the first distribution area is smaller than the second distribution area, one surface of the throw pillow corresponding to the first distribution area is marked as an arm surface, and the other surface of the throw pillow corresponding to the second distribution area is marked as a trunk surface.

In the usage method of the bolster for monitoring physiological signals provided by the embodiment, a plurality of medium sensors are deployed at multiple points on the bolster, so that a trunk surface and arm surfaces of a user when using the bolster can be distinguished through medium sensing signals; and a plurality of pressure sensors are arranged at multiple points on the throw pillow, the breathing signal and the heartbeat signal of the user can be obtained by processing a plurality of pressure sensing signals distributed on the trunk surface through a difference method, and the encircling pressure signal of the user is obtained by corresponding processing on the arm surface. The bolster is through monitoring user's breathing signal, heartbeat signal and embracing pressure signal's constantly change respectively to the change of data such as respiratory rate, respiratory intensity, rhythm of the heart, strength, the power of embracing when corresponding the obtaining user uses the bolster makes the bolster have more functional, can satisfy consumer's diversified demand.
