The use of the mouse is to make the operation of the computer easier, to replace the cumbersome instructions of the keyboard, and to send various related instructions to the computer.

Blood oxygen monitoring refers to monitoring the ratio of hemoglobin carrying oxygen to hemoglobin not carrying oxygen in human arteries. The pulse is the pulsation of the artery. With the rhythmic contraction and relaxation of the heart, the arterial wall expands and retracts accordingly, and the pulsation can be felt on the superficial artery. Human blood oxygen and pulse contain rich physiological and pathological information. A large number of clinical measurement results have confirmed that the level of blood oxygen and pulse characteristics are closely related to cardiovascular and cerebrovascular diseases. The level of blood oxygen and the comprehensive information of the form, intensity, and speed of the pulse wave do reflect many physiological and pathological characteristics of the human heart and cerebrovascular system to a considerable extent. Therefore, it is very important to obtain the blood oxygen and pulse conditions of the human body in a simple and easy way.

At present, although the mouse has become one of the necessary equipment for people's daily life and work, it is only used as an input device for the computer, and cannot be used to monitor the blood oxygen level and pulse situation of the mouse user itself, so that the mouse can be used.
