[0039] The present invention adds a real-time monitoring function of pressure data on the basis of the existing hip brace. When the pressure of an airbag is lower than the set value, the system will trigger the air pump 9 to inflate the airbag until the set pressure value is reached; once the pressure of the airbag is higher than the set value, the solenoid valve will be opened to release the gas, thereby keeping the pressure of the airbag within the set range. Through real-time pressure monitoring, the alarm function of abnormal pressure conditions can be realized, and the fixed state of the brace can be automatically adjusted in time to meet the doctor's expectations of the pressure value applied to the patient's hip joint, avoiding the problem of inconvenience in adjusting the hip brace for patients, and reducing the incidence of complications / disability, ensuring the effects of surgery, treatment, and rehabilitation, and alleviating the pain of patients.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] (1) The present invention avoids the shortcomings of conventional hip joint braces, such as the inability to standardize the tightness of the straps during wearing, which leads to inconvenience in wearing, poor comfort, and inability to ensure the fixation effect. For example, if the straps are too tight, the patient will feel uncomfortable and the blood circulation of the affected limb will be affected. If the straps are too loose, the brace will not be able to effectively fix the hip joint, affecting the effect of surgical treatment and slowing down the recovery process.

[0042] (2) The present invention uses a pressure sensor to detect the real-time pressure value of the brace tightness, so as to achieve the standardization and scientificization of the wearing and fixing tightness of the hip brace, and improve 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 reducing the service costs of hospitals, doctors and technicians, and improving the comfort of patients.
