[0025] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, the cervical support for postoperative care of the cervical spine proposed by the present invention comprises a front piece 1 and a rear piece 2, and the front piece 1 and the rear piece 2 are connected by Velcro. The method of connecting by Velcro is the same as the prior art, and will not be repeated here.

[0027] The front piece 1 includes a chin pad 11, a first airbag 111 is arranged on the surface of the chin pad 11, and a plurality of first pressure sensors (not shown in the figure) are arranged on the surface of the first airbag 111 in contact with the human body, and the first pressure sensors are used to detect the contact pressure between the first airbag 111 and the human body, and control the inflation and deflation of the first airbag 111 according to the contact pressure. The first airbag 111 is used to control the activity space of the cervical vertebra in the vertical direction.

[0028] The back panel 2 includes a neck support 21 and a head support 22, and the neck support 21 and the head support 22 are an integral structure. Figure 2 As shown, the inner walls on both sides of the neck support 21 are provided with second airbags 211, and the surface of the second airbags 211 in contact with the human body is provided with a plurality of second pressure sensors (not shown in the figure). The second pressure sensors are used to detect the contact pressure between the second airbags 211 and the human body, and the inflation and deflation of the second airbags 211 are controlled according to the contact pressure. The second airbags 211 are used to control the horizontal activity space of the cervical spine. The neck support 21 has a plurality of piezoelectric film sensors 212 evenly arranged along the column direction at the central position of the inner wall at the rear end. The piezoelectric film sensor 212 uses the LDT0-028K piezoelectric film sensor launched by TE Company. The piezoelectric film sensor collects the electromyographic signal of the human body. A plurality of massage electrode patches 213 are evenly arranged along the column direction on both sides of the piezoelectric film sensor 212. The massage electrode patches 213 perform low-frequency pulse electric massage at a current frequency of 30Hz to relieve neck fatigue. A processor 221 is arranged on the outer wall of the head support 22. A telescopic plate 23 is arranged on the top of the head support 22, as shown in FIG. Figure 3 As shown, arc-shaped detection modules 24 are symmetrically arranged on both sides of the top of the telescopic plate 23. Figure 4 As shown, the detection module 24 includes a support rod 2401, a first fixed plate 2406, a second fixed plate 2408 and a display screen 2411. The support rod 2401 is an arc-shaped structure. The environment perception camera 2402, the microphone 2403 and the speaker 2404 are arranged on the surface of the support rod 2401. The environment perception camera 2402, the microphone 2403 and the speaker 2404 are all facing away from the head. The support rod 2401 is connected to the first fixed plate 2406 through a telescopic rod 2405. The first fixed plate 2406 is connected to the second fixed plate 2408 through a horizontal rotating shaft 2407. The second fixed plate 2408 is connected to the display screen 2411 through a turntable 2410. The turntable 2410 can rotate 360° in the vertical direction. A mobile positioning camera 2409 is arranged on the upper surface of the second fixed plate 2408, and the mobile positioning camera 2409 faces the head. The telescopic rod 2405 moves under the drive of the first micro motor, the horizontal shaft 2407 rotates under the drive of the second micro motor, and the turntable 2410 rotates under the drive of the third micro motor. Both the environment perception camera and the mobile positioning camera use micro cameras.

[0029] The processor is connected to the first pressure sensor, the second pressure sensor, the first micromotor, the second micromotor and the third micromotor in a wireless communication manner, and the processor is connected to the piezoelectric film sensor, the environmental perception camera, the microphone, the speaker and the mobile positioning camera in a wired communication manner.

[0030] The functions of the cervical collar include:

[0031] 1) The processor receives data from the first pressure sensor and the second pressure sensor, compares the pressure data with a set standard value, and controls the inflation and deflation of the first airbag and the second airbag according to the comparison result, so that the patient's cervical spine movement is within a safe range in both the vertical and horizontal directions.

[0032] 2) The processor receives the electromyographic signal from the piezoelectric film sensor, determines the fatigue degree of the neck based on the electromyographic signal, and controls the massage intensity of the massage electrode patch according to the fatigue degree. The specific process of determining the fatigue degree of the neck based on the electromyographic signal is to amplify the collected electromyographic signal, use the Butterworth filter model and the wavelet noise reduction module to perform noise reduction on the amplified electromyographic signal, use the principal component analysis method to extract the signal features of the electromyographic signal after noise reduction, compare the signal features with the fatigue feature library, and determine the fatigue degree of the patient's neck. The fatigue feature library stores typical signal features corresponding to normal state, mild fatigue, and severe fatigue. The process of comparing the signal features with the fatigue feature library and determining the fatigue degree of the patient's neck is to calculate the similarity between the signal features and the typical signal features in different situations in the fatigue feature library, and output the situation corresponding to the typical signal feature with the highest similarity as the judgment result. The specific process of controlling the massage intensity of the massage electrode patch according to the fatigue degree is as follows: if the fatigue degree is in a normal state, the massage electrode patch does not work; if the fatigue degree is mild fatigue, the current intensity of the massage electrode patch is set to a first intensity; if the fatigue degree is severe fatigue, the current intensity of the massage electrode patch is set to a second intensity, and the second intensity is greater than the first intensity.

[0033] 3) The processor determines the patient's state and controls the working state of the detection module according to the patient's state. The process of determining the patient's state is to receive the picture taken by the environmental perception camera and compare the two pictures taken before and after. If the similarity is greater than 80%, it means that the surrounding scene has not changed and the patient is in a static state. Otherwise, the patient is in motion. The specific process of controlling the working state of the detection module according to the patient's state is that if the patient is in a static state, the processor controls the first micro motor, the second micro motor and the third micro motor according to the image of the mobile positioning camera, so that the display screen is located in front of the eyes, and the picture taken by the environmental perception camera is displayed on the display screen. The patient can learn about the surrounding situation through the display screen without moving the cervical spine. If the patient is in motion, the processor receives the image from the environmental perception camera and the sound from the microphone, and determines whether there is danger around by analyzing the image and sound. When there is danger, the patient is informed through the speaker to ensure the patient's life safety.

[0034] The above disclosure is only the preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the present invention. It should be pointed out that for those skilled in the art, any equivalent changes made to the scheme of the present invention without departing from the design structure and principle of the present invention are considered to be within the protection scope of the present invention.
