[0019] The pressure sensor 1 includes a pressure probe 11, a piezoelectric film 12, and a back shell 13, the pressure probe 11 is in contact with a portion to be tested, the back shell 13 is disposed at an outermost side away from the portion to be tested, and the piezoelectric film 12 is placed at a pressure. Between the probe 11 and the back shell 13. The blood oxygen sensor 2 includes a blood oxygen probe 21, and the blood oxygen probe 21 is integrated on the pressure sensor 1. It is understood that the setting position of the blood oxygen probe 21 is diverse. For example, referring to FIG. 1, the blood oxygen probe 21 can be built in. In the pressure probe 11, the pressure probe 11 and the blood oxygen probe 21 are brought into contact with the portion to be tested. Alternatively, referring to FIG. 2, the blood oxygen probe 21 can be built in the back shell 13 of the pressure sensor 1, so that the subject presses the pressure sensor 1吋 with a finger, the pressure probe 11 can contact the portion to be tested, and the blood oxygen probe 21 can The subject's pressure finger takes blood oxygen data. Therefore, the sensor acquisition platform can simultaneously collect blood oxygen data and blood vessel pulse pressure data of the human body.

[0020] It should be noted that the above pressure sensor 1 includes, but is not limited to, a film pressure sensor 1, a graphene carbon tube flexible film pressure sensor 1, an array type cantilever blood vessel pulse pressure sensor 1, and the like. Wherein, the outer layer of the graphene carbon tube flexible film pressure sensor 1 is a sensor capable of sensing pressure, and is made of plastic plus carbon nanotubes. The inner layer of the graphene carbon tube flexible film pressure sensor 1 is a flexible electronic circuit, which can put pressure The signal changes to an electrical signal.

[0021] Further, the blood oxygen sensor 2 described above includes, but is not limited to, a reflective blood oxygen sensor 2 and a transmissive blood oxygen sensor 2. [0022] Further, the above-mentioned sites to be tested include, but are not limited to, brachial artery blood vessels, temple blood vessels, ulnar artery blood, fingers, and the like.

[0023] The following is an example in which the pressure sensor 1 is a membrane pressure sensor 1, and the blood oxygen sensor 2 is a reflective blood oxygen sensor 2. The working principle of the sensor acquisition platform is as follows:

[0024] The reflective oximeter 21 is built in the pressure probe 11 of the membrane pressure sensor 1, and the reflective oximeter 2

1 and the pressure probe 11 is in contact with the part to be tested, so the sensor acquisition platform can synchronously collect the blood oxygen data and the blood vessel pulse pressure data of the human body.

[0025] The reflective blood oxygen probe 21 is built in the back shell 13 of the membrane pressure sensor 1, and the tester first contacts the pressure probe 11 of the membrane pressure sensor 1 with the portion to be tested, and then presses the membrane pressure sensor 1 through the finger. The back shell 13 presses the pressure probe 11 so that the pressure probe 11 is in close contact with the body surface blood vessel portion of the measured portion, so that the membrane pressure sensor 1 can accurately acquire the blood vessel pulse pressure. At the same time, considering the principle of the forward and reverse transmission and interaction of the mechanics, the reflective blood oxygen probe 21 in the back shell 13 of the membrane pressure sensor 1 can obtain blood oxygen data from the pressed finger. Therefore, the sensor acquisition platform can simultaneously collect blood oxygen data and blood vessel pulse pressure data of the human body.

In addition, the pressure sensor 1 further includes a housing 14 for mounting the pressure probe 11, the piezoelectric film 12, and the back shell 13, and a probe counterbore is disposed on a side of the housing 14 near the portion to be tested. Then, the manner in which the pressure probe 11 of the pressure sensor 1 is in contact with the portion to be tested includes, but is not limited to, the following two cases:

[0027] When the pressure probe 11 of the pressure sensor 1 directly contacts the portion to be tested, the pressure probe 11 directly protrudes from the counterbore of the probe and contacts the portion to be tested, and a crosshair is disposed on the edge of the counterbore of the probe. When the size of the pressure sensor 1 is small, after the pressure probe 11 is set, the visual processing in the brain of the subject automatically derivates the intersection of the two defects.

[0028] When the pressure probe 11 of the pressure sensor 1 is not directly in contact with the portion to be tested, the outer side of the counterbore of the probe is covered with a transparent barrier layer, and the transparent barrier layer is marked with an aiming cross.

The specific working principle of the processing device 3 is as follows:

[0030] According to the blood pressure tension measurement principle, when the pressure applied to the pressure probe 11 of the pressure sensor 1 for measuring the blood vessel pulse pressure is equivalent to the blood vessel wall pressure, the amplitude of the blood pressure wave is the strongest. Judging by the amplitude extremes of the blood pressure wave, the pole can be selected as a screening criterion for the optimal collection point of blood oxygen data and blood vessel pulse pressure data. In addition, by using the amplitude pole of the blood pressure wave as an auxiliary criterion, the blood vessel is flat and the degree of contact of the pressure probe 11 with the skin is stable and measurable, and thus the parameter of the blood vessel pulse pressure can be used as an auxiliary criterion for optimal blood oxygen data screening.
