[0010] Step S1, the patient's head is leaned against the front support part of the bed, and the head is located in the filling arrangement end face sensing area in the array, and then the torso is placed in the lower end area of the bed, and the head angle pressure distribution surface analysis module, the bed head end angle verification and elimination component and the main body transmission angle monitoring module are started to start the monitoring command;

After the adjustment is completed, the pressure distribution points applied by the patient's head to the multi-point pressing sensing summary unit on the inner side of the filling arrangement end surface area in the array are changed. According to the change in the pressure distribution points, it is judged that the patient's current head is in the lateral direction or the forward direction, and the head placement surface covering guide rail is used to drive the head placement surface monitoring unit to move horizontally, so that the head placement surface monitoring unit collects the lateral space occupied by the patient's head placement angle according to the distance signal between the head and the head placement surface covering guide rail during the movement of the head placement surface monitoring unit. The lateral space occupied by the patient's head placement angle is used to re-confirm that the patient's current head is in the lateral direction or the forward direction through the lateral space occupied by the patient's head placement angle, and then the patient's head placement state at the current bed angle is determined;

The head angle pressure distribution surface analysis module 2 is used to analyze the pressure distribution surface of the head after the angle is adjusted within the interval of the front end support part 11 of the bed. The head end angle verification and error elimination component 3 is used to eliminate the acquisition error of the head angle pressure distribution surface analysis module 2 caused by abnormal movement of the head. The main transmission angle monitoring module 4 is used to capture the offset path caused by the angle flipping of the front end support part 11 of the bed, which is used for secondary verification with the patient's head placement angle data.
[0023] In this embodiment, in order to solve the problem that the existing bed angle monitoring method determines the patient's current lying angle based on the rotation inclination angle of the head of the bed and the tilt dynamics of the head of the bed, when the patient's head changes in the lateral direction or the forward direction, errors in the collection surface and the collection data will be generated. The present invention proposes a real-time monitoring system for the bed angle, which eliminates the monitoring error by setting a head angle pressure distribution surface analysis module 2, a head end angle verification and error elimination component 3 and a main body transmission angle monitoring module 4.
[0024] The head angle pressure distribution surface analysis module 2 includes an array filling arrangement end surface 21, a multi-point pressing sensing summary unit 22, a head placement surface covering guide rail 23 and a head placement surface monitoring unit 24. The array filling arrangement end surface 21 is fixedly connected to the inner side of the front end support part 11 of the bed. The multi-point pressing sensing summary unit 22 is arranged in a matrix distribution on the upper end surface of the array filling arrangement end surface 21. The multi-point pressing sensing summary unit 22 is used to obtain the pressure signal triggered corresponding to the patient's current head placement angle. The head placement surface covering guide rail 23 is fixedly connected to the inner side of the front end support part 11 of the bed, and the head placement surface covering guide rail 23 is located above the array filling arrangement end surface 21. The head placement surface monitoring unit 24 is slidably connected to the inner side of the head placement surface covering guide rail 23. The head placement surface monitoring unit 24 is used to verify the lateral space occupied by the patient's head placement angle.
[0025] In this embodiment, a pressure sensor 22 is selected. When the patient's head state changes lateraly, the head placement surface covering guide rail 23 is used to drive the head placement surface monitoring unit 24 to move laterally, so that the head placement surface monitoring unit 24 collects the lateral space occupied by the patient's head placement angle according to the distance signal between the head and the head placement surface covering guide rail 23 during the movement. The lateral space occupied by the patient's head placement angle is used to reconfirm whether the patient's head is currently in the lateral direction or the forward direction, thereby determining the patient's head placement state at the current bed angle.
[0026] The bedside angle verification and error elimination component 3 includes a vertically placed bed edge 31, a height measurement and adjustment component 32 and a sound wave signal generating sensor unit 33. The vertically placed bed edge 31 is fixedly connected to the inner side of the front end support part 11 of the bed. The sound wave signal generating sensor unit 33 is fixedly connected to the vertically placed bed edge 31 through the height measurement and adjustment component 32. The sound wave signal generating sensor unit 33 is used to sense whether the patient's head placement height exceeds the angle monitoring surface, thereby eliminating the data error collected by the head angle pressure distribution surface analysis module 2.
[0027] In this embodiment, in order to prevent monitoring errors caused by the patient's standing up action, when the patient stands up, the sound wave signal generating sensor unit 33 no longer senses the patient's head when monitoring height, that is, when the patient stands up, the sound wave signal generating sensor unit 33 senses that the patient's head placement height exceeds the angle monitoring surface. At this time, the signal feedback generated by the head placement surface monitoring unit 24 and the filling arrangement end surface 21 in the array is stopped until the patient returns to the angle monitoring surface, and then the signal feedback generated by the head placement surface monitoring unit 24 and the filling arrangement end surface 21 in the array is restarted. Through this processing method, the erroneous monitoring data generated by the patient after standing up on his own can be eliminated.
[0028] The main body transmission angle monitoring module 4 includes a flipping dynamic pressure sensing unit 41, a flipping pressure linkage applying unit 42 and a main body angle adjustment driving unit 43. The flipping dynamic pressure sensing unit 41 and the flipping pressure linkage applying unit 42 are both installed on the inner side of the front end support part 11 of the bed. The flipping dynamic pressure sensing unit 41 is connected to the rotating end of the front end support part 11 of the bed. The outer shell of the main body angle adjustment driving unit 43 and the flipping pressure linkage applying unit 42 are both connected to the fixed support end of the front end support part 11 of the bed. The output end of the main body angle adjustment driving unit 43 is connected to the rotating end of the front end support part 11 of the bed. The main body angle adjustment driving unit 43 is used to drive the front end support part 11 of the bed to flip. The flipping dynamic pressure sensing unit 41 and the flipping pressure linkage applying unit 42 sense the offset path generated when the front end support part 11 of the current bed is flipped, and are used for secondary verification with the patient head placement data collected by the head angle pressure distribution surface analysis module 2.
[0029] In this embodiment, when the patient adjusts the flip angle of the front end support part 11 of the bed through the main body angle adjustment drive part 43, the flip dynamic pressure sensing unit 41 is driven by the front end support part 11 to move synchronously to generate pressure on the flip pressure linkage applying unit 42, so that the flip pressure linkage applying unit 42 obtains the movement angle of the front end support part 11 of the bed. The obtained movement angle of the front end support part 11 of the bed is used to judge whether the bed angle after the current adjustment of the front end support part 11 of the bed causes the pressure data error generated by the patient's head on the filling arrangement end surface 21 in the array. That is, when the medical terminal determines that the pressure data generated by 21 violates the preset parameters, it is determined that the pressure data error exists, so that the medical terminal can avoid misjudgment after obtaining the error.
[0030] The working principle of the present invention is: the patient's head is leaned against the front support part 11 of the bed, and the head is located in the sensing area of the filling arrangement end surface 21 in the array, and then the torso is placed in the area of the lower end 14 of the bed, and the head angle pressure distribution surface analysis module 2, the bed head end angle verification and difference elimination component 3 and the main body transmission angle monitoring module 4 are started to start the monitoring command. The patient adjusts the flip angle of the front support part 11 of the bed through the main body angle adjustment drive part 43 according to the head placement requirements. After the adjustment is completed, the pressure distribution point position applied by the patient's head to the multi-point pressing and sensing summary unit 22 in the inner side of the filling arrangement end surface 21 area in the array changes. According to the changes in the pressure distribution points, it is determined whether the patient's head is currently in the lateral direction or the forward direction, and the head placement surface covering guide rail 23 is used to drive the head placement surface monitoring unit 24 to move horizontally, so that during the movement of the head placement surface monitoring unit 24, the lateral space occupied by the patient's head placement angle is collected according to the distance signal between the head and the head placement surface covering guide rail 23. The lateral space occupied by the patient's head placement angle is used to re-confirm whether the patient's head is currently in the lateral direction or the forward direction, and then the patient's head placement state at the current bed angle is determined. When the patient gets up under the monitoring state, a signal is generated through sound waves. The sensor unit 33 senses whether the height of the patient's head exceeds the angle monitoring surface, that is, when the patient stands up, the acoustic wave generates a signal. The sensor unit 33 senses that the height of the patient's head exceeds the angle monitoring surface. At this time, the signal feedback generated by the head placement surface monitoring unit 24 and the filling arrangement end surface 21 in the array is stopped until the patient returns to the angle monitoring surface. The signal feedback generated by the head placement surface monitoring unit 24 and the filling arrangement end surface 21 in the array is restarted, thereby eliminating the data errors collected by the head placement surface monitoring unit 24 and the filling arrangement end surface 21 in the array after the patient stands up, avoiding the erroneous signal from being sent to the medical terminal, and at the subject angle When the debugging driving part 43 debugs the flipping angle of the front end support part 11 of the bed, the front end support part 11 of the bed drives the flipping dynamic pressure sensing unit 41 to move synchronously to generate pressure on the flipping pressure linkage applying unit 42, so that the flipping pressure linkage applying unit 42 is flipped synchronously after receiving the pressure generated by the flipping dynamic pressure sensing unit 41, thereby accurately obtaining the movement angle of the front end support part 11 of the bed, judging whether the bed angle of the current front end support part 11 after debugging causes the pressure data error generated by the patient's head on the filling arrangement end surface 21 in the array, and then substituting the pressure data error corresponding to the current bed angle to eliminate the error parameters.
