The blood oxygen measuring device belongs to the technical field of medical instruments, is mainly used for measuring the blood oxygen saturation, and the blood oxygen saturation is one of important basic data in clinical medical treatment and is an important physiological parameter for reflecting whether the oxygen content in the respiratory function and blood of a human body is normal or not. By measuring the blood oxygen saturation, the blood oxygen content of the patient can be known in time, the health state of the patient is monitored, and the method has great clinical value.

At present, blood oxygen sensor mainly includes finger clip formula blood oxygen sensor, finger stall formula blood oxygen sensor and bandage formula blood oxygen sensor, and these three kinds of blood oxygen sensors all can be worn on patient's finger, make the device compress tightly the finger through elastic element, self deformation, bandage respectively, make its firm the fixing on the finger for providing bigger clamp force.

However, the length of the ventral side of the three blood oxygen sensors is too long, so that the sensors are easily displaced due to daily finger movement, the light path is affected, false alarm is caused, and even the sensors are separated from the fingers, and normal monitoring cannot be performed, for example, when a patient holds an article or holds a handrail, the fingers of the probe can be squeezed or pushed.

In addition, the blood oxygen sensor is easily pulled by the cable of the blood oxygen sensor when the patient moves, and these also can cause the blood oxygen sensor to shift or be separated from the finger, thereby affecting the light path of the blood oxygen sensor and causing the blood oxygen sensor to be incapable of monitoring normally.

As shown in fig. 1 to 19, according to a first aspect of the present application, there is provided an blood oxygen sensor assembly 100, comprising a sensor body 100a, a knuckle fixing part 50, a cable 70 and a blood oxygen detecting assembly, wherein the sensor body 100a has a receiving part for at least partially receiving a finger 200, the blood oxygen detecting assembly comprises an emitting device and a receiving device which are oppositely arranged, the receiving device is used for receiving an optical signal emitted by the emitting device, the emitting device and the receiving device are oppositely arranged, one end of the cable 70 is connected with the blood oxygen detecting assembly, the other end extends from the sensor body 100a, and the knuckle fixing part 50 is arranged at a distance from the sensor body 100a and is used for being fixed on the finger 200.
