Mobile phone case with infrared temperature measurement, heart rate blood oxygen monitoring and Bluetooth transmission function

technical field

The invention belongs to the field of intelligent monitoring equipment for body temperature, heart rate and blood oxygen, in particular to a mobile phone case with infrared temperature measurement, heart rate blood oxygen monitoring and Bluetooth transmission functions.

Background technique

Body temperature is an important indicator of human health. Normal body temperature is a necessary condition to ensure normal metabolism and life activities. The measurement of body temperature is often the first step in disease diagnosis. Various new technologies have been applied to the measurement of body temperature. Commonly used thermometers have shifted from mercury thermometers to fast and efficient electronic thermometers. Heart rate is also an important indicator of human health that is difficult to measure. Changes in heart rate are closely related to heart disease. Blood oxygen refers to the oxygen content in the blood. The higher the oxygen content in the blood, the better the metabolism of the human body. Parameters are often difficult to measure accurately and rely on specialized equipment in hospitals.

The currently commonly used thermometers are generally mercury thermometers and electronic thermometers, which are contact-based measurement with low efficiency and the risk of infecting patients in the context of infectious diseases. Although devices such as forehead thermometers that rely on infrared temperature measurement avoid this shortcoming, However, its low precision and large size make it difficult to carry around; the measurement of two important human parameters, heart rate and blood oxygen concentration, often relies on professional equipment in hospitals, making it difficult to enter people's daily lives. Therefore, it is necessary to invent a mobile phone case with the functions of infrared temperature measurement, heart rate blood oxygen monitoring and Bluetooth transmission, which is simple in structure, stable in performance, high in precision, and can be carried around.
