Abstract

The invention discloses an alarm wristband and relates to an alarm device. The alarm wristband comprises a waterproof housing, and a voltage follower, a pulse sensor, a pulse signal amplifier, a signal amplitude amplifier and a display alarm circuit which are arranged in the housing, wherein the pulse sensor, the pulse signal amplifier, the signal amplitude amplifier and the display alarm circuit are sequentially connected; the voltage follower is connected between the pulse sensor and the signal amplitude amplifier; the pulse sensor comprises a storage battery used for supplying power for the circuit, a switch connected with the storage battery, a voltage stabilizer IC1 connected with the switch, and two current-limiting resistors (a resistor R1 and a resistor R2) connected with the output terminal of the voltage stabilizer IC1; and the resistor R1 is connected with an infrared transmitting tube LED 1, the resistor R2 is connected with a photoresistor R17, and the photoresistor R17 receives infrared rays emitted by the infrared transmitting tube LED 1.

Description

technical field [0001] The invention relates to an alarm device, in particular to an alarm bracelet. Background technique [0002] The pulse of the human body is consistent with the heart rate, so as long as the pulse number is measured, the corresponding heart rate can be measured. Clinically, body temperature, pulse, respiration, and blood pressure are collectively referred to as vital signs. The pulse range is 60-100 beats per minute, and the elderly are slower at 55 to 60 beats per minute. When the pulse rate per minute is lower than 50, it is bradycardia, and if it is higher than 160, it is tachycardia. Both slowness and speed may bring life danger, which is very dangerous for heart patients, and heart disease It can be sudden, even if it is confirmed that they have heart disease, it is impossible to predict when it will occur. For some people who have health problems but do not need hospital observation or long-term treatment, they are no different from ordinary peop...
