One specific application of this embodiment is: when the wrist-mounted display finger stall is used, the display bracelet 2 is worn on the wrist, the monitoring finger stall 1 is worn on the thumb, and the position of the monitoring finger stall 1 is adjusted to enable the built-in sensor module 4 to be tightly attached to the abdomen of the thumb. After finishing wearing, long press the function button on showing bracelet 2 and light up to liquid crystal display and realize the start function. After the machine is started, the display screen alternately displays the acquired pulse, finger temperature and blood oxygen saturation, if certain physiological signal data is lower than a normal fluctuation range, the display screen flickers to display the physiological signal value, and the buzzer makes a 'drop' sound to achieve a prompt effect.

As shown in fig. 1, the light source transceiver 403 emits light with different wavelengths to the skin, and detects the intensity of the reflected light to obtain different physiological signal data.

And (3) measuring the pulse: because the heart beats, the blood volume in the blood vessel can have rhythmic change, a part of the light emitted by the light source transceiver 403 can be absorbed by the blood in the blood vessel, the larger the blood volume is, the more the light is absorbed, the less the light is reflected back, along with the rhythm of the heart beat, the blood volume in the blood vessel periodically changes, the detected reflected light intensity also changes, according to the change interval of the detected light intensity signal, the heart rate and pulse data can be calculated, if the incident light is green light, the reflected light caused by the heart beat changes greatly, and therefore the light source transceiver emits the green light for monitoring the pulse signal.

Measuring finger temperature: the built-in sensor module integrates a temperature sensor, can monitor the skin temperature of the finger, and can realize early warning of frostbite.

Measuring the blood oxygen saturation: the blood oxygen saturation is the percentage of the volume of oxyhemoglobin combined by oxygen in blood to the volume of all combinable hemoglobin, and the oxygen, the hemoglobin and the deoxyhemoglobin can selectively absorb red light with the wavelength of 660nm and infrared light with the wavelength of 940nm, and the concentration ratio of the oxygen, the hemoglobin and the deoxyhemoglobin can be obtained through algorithm processing by detecting the intensity of the reflected red light and the infrared light, so that the blood oxygen saturation of a human body is obtained.

Since the heart produces electrical activation before mechanical contraction, the current of myocardial activation can be conducted from the heart through body tissues to the body surface, causing different potential changes at different parts of the body surface. The sensor module 4 built in the finger cot integrates an electrocardio detection module 404, and electrocardio waveforms are obtained by detecting the potentials of the left hand and the right hand and then processing the potentials by an algorithm. There are two options for monitoring locations:

firstly, monitoring the electric potential at the abdomen of the thumbs of both hands, and after the finger cot is worn, pressing the thumb of the other hand on the sensor module 4, wherein in the mode, a right leg driving signal is simulated by the first main controller 401;
