[0061] Step c: Send the read patient information to the intelligent terminal 10 for medical staff to confirm; Sending the read patient information to the intelligent terminal 10 for medical staff to confirm increases the safety and reliability of the treatment process;

[0062] Step d: Use the wearable blood oxygen and blood pressure monitor 9 to measure the patient's vital signs in real time and send them to the intelligent terminal 10; Using the wearable blood oxygen and blood pressure monitor 9 to monitor the patient's vital signs in real time ensures the real-time understanding and rapid response to the patient's health status;

[0063] Step e: Compare the measurement results with the threshold of the normal vital signs set by the remote monitoring software on the intelligent terminal 10; By comparing the measurement results with the preset threshold, medical staff can make preventive medical decisions and adjust the treatment plan in a timely manner;

[0064] Step f: When the patient's vital signs are lower than the preset threshold, the remote monitoring software triggers an alarm and activates the self-unlocking system; when the patient's vital signs are lower than the preset threshold, the remote monitoring software triggers an alarm and activates the self-unlocking system, improving the response ability to emergency situations of the patient.

[0065] Step g: The intelligent terminal 10 controls the air pump 204 to inflate the loose airbag 202, pushing the fixator locking slider 201 to achieve the loosening of the patient fixator 100, providing a time advantage for emergency medical intervention.
