Intelligent mouth opening rehabilitation device

An intelligent mouth opening rehabilitation device, comprising:

• a body, wherein an end of the body is provided with an upper bite pad and a lower bite pad;
• a pressure sensor, provided in the upper bite pad and/or the lower bite pad, for detecting pressure data on the upper bite pad and/or the lower bite pad;
• a stepping motor, for driving the upper bite pad and/or the lower bite pad to swing longitudinally;
• and
• a processor, for controlling the stepping motor to operate or stop according to the pressure data and/or a preset training instruction, thereby driving the upper bite pad and/or the lower bite pad to swing longitudinally or to stop;
• wherein the processor controlling the stepping motor to operate or stop according to the pressure data comprises:
• the processor compares the pressure data with a preset pressure threshold in real time;
• if the pressure data are lower than the preset pressure threshold, the processor controls the stepping motor to operate forward, to enable the upper bite pad to swing up a distance and/or the lower bite pad to swing down a distance, then returns to the first operation;
• and if the pressure data are not lower than the preset pressure threshold, the processor controls the stepping motor to stop operating, to enable the upper bite pad and/or the lower bite pad to stop swinging;
• wherein the preset pressure threshold is set by testing a patient's pain performance in combination with a physician's observations when the physician instructs the patient on the use of the mouth opening rehabilitation device in an early stage;
• wherein the processor controlling the stepping motor to operate or stop according to the pressure data further comprises:
• the pressure sensor detects the pressure data in real time to determine whether the pressure data reach a second pressure threshold;
• and if the pressure data reach the second pressure threshold, the processor controls the stepping motor to operate reversely, thereby enabling the upper bite pad to swing down a distance and/or the lower bite pad to swing up a distance, then returns to the first operation;
• wherein the second pressure threshold is greater than the preset pressure threshold, so that the patient increases a pressure exerted on the upper bite pad and the lower bite pad through upper and lower jaws of a mouth of the patient to reduce an opening angle between the upper bite pad and the lower bite pad, when the patient wants to interrupt a mouth opening training or when the patient wants to reduce the opening angle due to increasing soreness of the oral-jaw muscles.
