[0021] like Figure 1-Figure 3 As shown, this embodiment provides a head and neck brace, including a support shell 1, which is annular and can be mounted on the head and neck of a human body to support and fix the head and neck of a human body. An inflation and deflation device is provided on the outside of the support shell 1, and the inflation and deflation device is connected to a control main board 2, and the control main board 2 controls the inflation and deflation device to perform inflation and deflation work. At least two airbags 3 protruding from the surface of the support shell 1 are provided on the inside of the support shell 1, and at least two airbags 3 are arranged at equal intervals, and both airbags 3 are connected to the inflation and deflation device, and the inflation and deflation device inflates and deflates each airbag 3.

[0022] A pressure detection device is provided on the side surface of the airbag 3 close to the human head and neck. The pressure detection device is connected to the control main board 2. The pressure detection device uses a pressure sensor. The pressure sensor can detect the pressure of the airbag 3 on the human head and neck. According to the pressure detection data of the pressure sensor, the tightness of the head and neck brace can be analyzed. The control main board 2 is used to control the working state of the inflation and deflation device based on the pressure information detected by the pressure detection device, dynamically adjust the pressure of the airbag 3 on the human head and neck, and thus adjust the tightness of the head and neck brace.

[0023] Each airbag 3 is individually regulated. When the pressure detection data of the pressure sensor is too large, the head and neck brace is too tight, and the airbag 3 is deflated to reduce the gas in the airbag 3, thereby reducing the pressure of the airbag 3 on the human head and neck, and making the head and neck brace looser; when the pressure detection data of the pressure sensor is too small, the head and neck brace is too loose, and the control main board 2 inflates the airbag 3 through the inflation and deflation device, increases the gas in the airbag 3, increases the pressure of the airbag 3 on the human head and neck, and makes the head and neck brace tighter.

[0024] The present invention monitors the pressure of the airbag 3 on the human head and neck in real time through the pressure detection device, and can adjust the fixing state of the head and neck brace in time, effectively avoiding the incidence of complications / disability, ensuring the effect of surgery, treatment and rehabilitation, and alleviating the patient's pain. In addition, the airbag 3 adjusts the pressure value through inflation and deflation actions to achieve the doctor's expected pressure value applied to the patient's head and neck, which is conducive to the standardization and scientificization of the wearing and fixing tightness of the head and neck brace and improves the patient's comfort.

[0025] like Figure 1 and Figure 2 As shown, specifically, the support shell 1 includes a strip-shaped flexible support body 4, the airbag 3 is arranged on the surface of the flexible support body 4, a first connection structure is arranged at one end of the flexible support body 4, and a second connection structure is arranged at the other end of the flexible support body 4, and the second connection structure is connected to the first connection structure, so that the flexible support body 4 is annularly sleeved on the head and neck of the human body. The flexible support body 4 is bent into a ring shape and fixed to the first connection structure through the second connection structure, and then the pressure of the airbag 3 on the head and neck of the human body is adjusted by adjusting the inflation state of the airbag 3. In order to improve the comfort of the patient, the flexible support body 4 includes a flexible support plate, and a skin-friendly cushion is arranged on the surface of the flexible support plate.

[0026] The first connection structure and the second connection structure are connected or bonded to each other, which is convenient to use, and the support shell 1 can adjust its size according to different patients to meet the needs of different patients.

[0027] like Figure 2As shown, in one embodiment, the first connection structure includes a Velcro hook surface 5, and the second connection structure includes a Velcro fleece surface 6, and the Velcro hook surface 5 and the Velcro fleece surface 6 are bonded to each other. The Velcro hook surface 5 and the Velcro fleece surface 6 are connected to each other, so that the flexible support body 4 can form a ring shape that fits the patient's head and neck, and the Velcro connection method has good adjustment effect and fastening effect, which can meet the needs of different patients.

[0028] In this embodiment, the side of the airbag 3 close to the human head and neck is provided with an arc-shaped fitting surface, the arc-shaped fitting surface matches the human head and neck, and the pressure detection device is arranged on the surface of the arc-shaped fitting surface. The airbag 3 of the present invention protrudes from the surface of the supporting shell 1, and the arc-shaped fitting surface on the surface of the airbag 3 matches the human head and neck, which can well adapt to the curvature change of the human head and neck, thereby improving the wearing comfort of the head and neck brace. Moreover, a pressure sensor is arranged on the surface of the arc-shaped fitting surface, which is conducive to further improving the detection accuracy of the pressure sensor. It should be noted that the number of airbags 3 in the present invention can be set according to actual needs. In this embodiment, two airbags 3 are displayed on the inner side of the supporting shell 1, but it does not limit the number of airbags 3.

[0029] like Figure 3 As shown, in one embodiment, the inflation and deflation device includes an air pump 7, the air pump 7 is connected to the control main board 2, an air intake pipe is provided between the air pump 7 and the air bag 3, an air intake port 8 is provided at one end of the air intake pipe, an air intake valve is provided on the air intake pipe, and the air intake valve is connected to the control main board 2; the air bag 3 is connected to an exhaust pipe, an exhaust port 9 is provided at one end of the exhaust pipe, an exhaust valve is provided on the exhaust pipe, and the exhaust valve is connected to the control main board 2. The inflation and deflation device also includes an outer cover 12 and a bottom plate 13, the air pump 7 and the control main board 2 are fixed on the bottom plate 13, the outer cover 12 is connected to the bottom plate 13, and the outer cover 12 provides protection for the air pump 7, the control main board 2, the air intake pipe and the exhaust pipe. Air holes are provided on the outer cover 12 for air intake and exhaust. Both the air inlet valve and the air outlet valve are electromagnetic valves. When the pressure detection data of the pressure sensor is too large, the airbag 3 needs to be deflated, and the control main board 2 opens the exhaust valve to exhaust air, reducing the gas in the airbag 3, reducing the pressure of the airbag 3 on the human head and neck, and making the head and neck brace looser; when the pressure detection data of the pressure sensor is too small, the airbag 3 needs to be inflated, and the control main board 2 opens the air inlet valve, and starts the air pump 7 to inflate the airbag 3 through the air inlet pipe, increase the gas in the airbag 3, increase the pressure of the airbag 3 on the human head and neck, and make the head and neck brace tighter. The present invention avoids the defects of existing head and neck braces after wearing, such as if the brace is too tight, the patient is uncomfortable to wear, which may affect the blood circulation of the affected limb, and if the brace is too loose, the brace cannot effectively fix the cervical spine, affecting the surgical treatment effect and slowing down the rehabilitation process.

[0030] The air pump 7 is connected to a power supply device, which supplies power to the air pump 7, the control mainboard 2 and other electronic components. Specifically, the power supply device includes a power supply battery, which is connected to the air pump 7 and is equipped with a charging interface module 10. Preferably, the power supply battery is a lithium battery 11, which can be recharged and used repeatedly, thereby improving the convenience of using the head and neck brace.

[0031] In one embodiment, a plurality of temperature detection devices are provided at intervals on the surface of one side of the airbag 3 close to the head and neck of the human body. The temperature detection device adopts a temperature sensor, and the temperature sensor is connected to the control main board 2, and the control main board 2 is connected to an alarm. The head and neck brace of the present invention has added a real-time monitoring function of pressure data on the basis of the original function, and timely warning. Through real-time pressure monitoring, the alarm function of abnormal pressure can be realized, and the fixed state of the brace can be adjusted in time, effectively avoiding the incidence of complications / disability, ensuring the effect of surgery, treatment, and rehabilitation, and alleviating the pain of patients. In addition, by controlling the air pump 7 to automatically inflate and deflate the pressure value, the doctor's expectation of the pressure value applied to the patient's head and neck can be achieved, avoiding the problem of inconvenience of patients adjusting the head and neck brace.

[0032] The present invention provides an intelligent head and neck brace that automatically monitors and adjusts pressure. The support shell 1 acts as an external support, and then the airbag 3 is inflated to apply pressure to the cervical spine to achieve the desired fixation effect. Each airbag 3 is equipped with a corresponding air inlet valve and exhaust valve. When the pressure of one of the airbags 3 is lower than the set value, the control mainboard 2 will trigger the air pump 7 to inflate the airbag 3 until the set pressure value is reached. Once the pressure is higher than the set value, the control exhaust valve will open to release the gas inside the airbag 3, thereby keeping the pressure of the airbag 3 within the set range. This automatic inflation and deflation method can ensure that the two airbags 3 always remain stable and are within the same pressure range. The present invention solves the problem that the pressure cannot be monitored in real time after wearing the brace, and can send an alarm signal when the brace is too tight or too loose. The brace fixation state is adjusted in time by inflating and deflation of the airbag 3 to avoid complications / disability and ensure the fixation effect.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] (1) The present invention avoids the shortcomings of existing head and neck braces, such as the inability to standardize the tightness of the brace during wearing, which leads to inconvenience in wearing, poor comfort, and inability to ensure the fixation effect. For example, if the brace is too tight, the patient will feel uncomfortable wearing it, which may affect the blood circulation of the affected limb; if the brace is too loose, the brace cannot effectively fix the cervical spine, which affects the effect of surgical treatment and slows down the recovery process.

[0035] (2) The contact surface between the airbag 3 and the cervical spine of the present invention is provided with a pressure sensor, which detects the real-time pressure value of the binding tightness effect through the pressure sensor, realizes the standardization and scientificization of the wearing and fixing tightness of the head and neck brace, and improves the comfort of the patient. This process is a standardized process with simple operation and no skill requirements for service personnel. It does not require professional manual execution, effectively reduces the service costs of hospitals, doctors and technicians, and ensures the wearing comfort of patients, effectively avoiding problems caused by wearing comfort and fixing effect.
