Furthermore, the oxygen adjusting device also comprises an air pump which is communicated with the infant incubator and can pump oxygen in the infant incubator with different powers, and when the respiratory frequency of the monitored object is too low, namely the oxygen concentration in the infant incubator is too high, the air pump can be opened with proper power to quickly reduce the oxygen concentration in the infant incubator, so that the respiratory frequency of the monitored object can be adjusted in a short time.
Furthermore, the oxygen adjusting device is also provided with a first electric valve and a second electric valve, the first electric valve is arranged on a communication channel between the oxygen supply machine and the infant incubator, and the second electric valve is arranged on a communication channel between the air pump and the infant incubator. The first electric valve is closed when the oxygen supply machine does not work, or the second electric valve is closed when the air extractor does not work, so that the infant incubator is isolated from the outside, and bacterial pollution is reduced.
According to some embodiments of the present invention, the process control device controls the oxygen regulating device as follows:
when the current oxygen concentration is less than the expected oxygen concentration, the first electric valve is opened to increase the oxygen supply concentration of the oxygen supply machine, so that the oxygen concentration in the infant incubator is increased.
When the current oxygen concentration is higher than the expected oxygen concentration, the second electric valve is opened, the power of the air extractor is increased, the oxygen supply concentration of the oxygen supply machine is reduced, and the oxygen concentration in the infant incubator is rapidly reduced.
According to some embodiments of the present invention, the data acquisition device comprises an oxygen concentration sensor disposed in the infant incubator, and the oxygen concentration sensor acquires the current oxygen concentration in the infant incubator in real time and transmits the current oxygen concentration to the process controller, so that the process controller can adjust the oxygen concentration in the infant incubator in real time.
According to some embodiments of the present invention, the non-contact respiration monitoring device may be a radar respiration monitoring device or a camera respiration monitoring device. The principle of the radar type respiration monitoring device is that the amplitude of thoracic cavity vibration, the heartbeat and the respiration frequency are different, and the distance difference value formed after the radar transmits electromagnetic waves for multiple times and then reflects the electromagnetic waves is also different, so that the radar is used for transmitting the electromagnetic waves, and the respiration frequency detection is realized by detecting the frequency of echo signals. The principle of the camera type respiration monitoring device is that a camera is utilized to track the chest area of a monitored object, and the chest movement waveform is determined by analyzing the pixel color change of the frames before and after the video stream of the chest area, so that the respiratory frequency of the monitored object is determined.
Further, referring to fig. 1, the respiration monitoring device comprises a binocular camera assembly and a first analysis module, the binocular camera assembly comprises a first camera and a second camera, the first camera and the second camera are respectively arranged on two sides of the infant incubator, and the chest video of the monitored object can be acquired when the infant turns over.

According to some embodiments of the present invention, the process of determining the desired oxygen concentration from the subject breathing rate in the process control device is as follows:
when the respiratory frequency of the monitored object is smaller than a first respiratory frequency threshold value, multiplying the current oxygen concentration by a first coefficient to obtain an expected oxygen concentration, wherein the first coefficient is smaller than 1;
and when the respiratory frequency of the monitored object is greater than a second respiratory frequency threshold, multiplying the current oxygen concentration by a second coefficient to obtain the expected oxygen concentration, wherein the second coefficient is greater than 1, and the first respiratory frequency threshold is less than the second respiratory frequency threshold.
In the embodiment, the breathing condition of the monitored object is determined by setting the first breathing frequency threshold and the second breathing frequency threshold, so that the oxygen concentration of the infant incubator is self-adaptively adjusted. When the subject breathing rate is between the first breathing rate threshold and the second breathing rate threshold, the current oxygen concentration of the infant incubator is the appropriate desired oxygen concentration for the subject, and therefore, no adjustment of the oxygen concentration of the infant incubator is required. When the respiratory rate of the monitored subject is less than the first respiratory rate threshold, it indicates that the current oxygen concentration of the infant incubator is too high for the monitored subject, therefore, the current oxygen concentration is multiplied by a first coefficient less than 1 to obtain an expected oxygen concentration less than the current oxygen concentration, so as to reduce the oxygen concentration of the infant incubator to the expected oxygen concentration, and then the oxygen concentration of the infant incubator is continuously reduced according to the current respiratory condition of the monitored subject and the current oxygen concentration until the respiratory rate of the monitored subject is between the first respiratory rate threshold and the second respiratory rate threshold. When the respiratory rate of the guardian is larger than the second respiratory rate threshold, the current oxygen concentration of the infant incubator is low enough for the guardian, therefore, the current oxygen concentration is multiplied by a second coefficient which is larger than 1 to obtain the expected oxygen concentration which is larger than the current oxygen concentration, so as to increase the oxygen concentration of the infant incubator to the expected oxygen concentration, and then the oxygen concentration of the infant incubator is continuously increased according to the current respiration condition of the guardian and the current oxygen concentration until the respiratory rate of the guardian is between the first respiratory rate threshold and the second respiratory rate threshold.
In this embodiment, the first coefficient may be a predetermined value slightly smaller than 1, such as 0.95, 0.9, etc., and the second coefficient may be a predetermined value slightly larger than 1, such as 1.05, 1.1, etc. Here, the first coefficient and the second coefficient may be dynamically set according to the breathing frequency of the subject, and the first coefficient a may be set when the inspiration interval time t of the subject is determined according to the breathing frequency 1 ＝B 1 T, second coefficient a 2 ＝B 2 T, wherein B 1 And B 2 The regulatory molecules are fixed for the first coefficient and the second coefficient, respectively.
According to some embodiments of the present invention, referring to fig. 1, the monitoring system of the infant incubator further comprises a temperature monitoring device, wherein the temperature monitoring device comprises an infrared sensing module, a third camera and a second analysis module.
