Of course, the patient applied to the respiratory arrest is only one embodiment of the present invention, and is not limited to the application range of the human head posture monitoring and adjustment system 100 of the present invention.

In this embodiment, the human body part posture monitoring and adjustment system 100 includes an air bag unit 10, an acceleration sensor 20, a processing module 30, and a pump control module 40. The acceleration sensor 20 and the processing module 30 can be fabricated in the same chip.

Referring to FIG. 2, the airbag unit 10 is a headrest and includes a plurality of inflatable pumps 11 therein. In this embodiment, four airbag units 10 are provided, and the airbag unit 10 provides the head placement of the patient.

Referring to FIG. 3, FIG. 4 and FIG. 5, the acceleration sensor 20 is mounted on the head of the patient (preferably the forehead) for detecting the change of the corner and the inclination of the patient's head posture, in this embodiment. The acceleration sensor 20 includes a sensing circuit 21, a vector rotation circuit 22 coupled to the sensing circuit 21, and a calculation circuit 23 coupled to the vector rotation circuit 22. The sensing circuit 21 is used to The head is rotated or moved to sense an acceleration vector presented by a right angle coordinate system The right angle coordinate system is defined by a first coordinate axis (Z axis), a second coordinate axis (X axis), and a third coordinate axis (Y axis) that are perpendicular to each other. Vector rotation circuit 22 for accelerating the vector Rotating around any coordinate axis, in detail, the vector rotation circuit 22 first accelerates the vector Rotate around the first coordinate axis (Z axis) (as shown in Figure 4) to make the acceleration vector The component projected on the XY plane overlaps the second coordinate axis (X axis) and forms a new acceleration vector , its position coordinates are (A' _X , 0, A _Z ), at this time, the acceleration vector after rotation Will fall on the plane formed by the XZ axis, and the calculation circuit 23 will calculate the acceleration vector The component length |A' _X | projected on the second coordinate axis (X-axis).

Acceleration vector Rotating only with the first coordinate axis (Z axis) axis, its own vector length does not change, relatively, the acceleration vector The length of the component projected on the XY plane is also not affected by the acceleration vector. The rotation is increased or decreased, so the acceleration vector after rotation The component length |A' _X | projected on the XY plane will be equal to the original acceleration vector The length of the component projected on the XY plane ( ).

Next, the vector rotation circuit 22 will apply the above-described rotated acceleration vector. Then rotate around the third coordinate axis (Y axis) (ie the acceleration vector on the XZ plane) Approaching the X axis), as shown in Figure 5, to make the acceleration vector Overlap on the second coordinate axis (X-axis) and form a new acceleration vector , its position coordinates are (A" _X , 0, 0), and the calculation circuit 23 calculates the acceleration vector Rotate to the angle δ of the overlapping X-axis, and then subtract the angle δ by π /2 to find the first angle φ of an independent coordinate system ( φ , θ , ψ ), as shown in Fig. 6.

In the same manner as described above, the vector rotation circuit 22 will accelerate the vector. Rotating around the second coordinate axis (X axis), making the acceleration vector The component projected on the YZ plane overlaps the third coordinate axis (Y axis) and forms a new acceleration vector , its position coordinates are (A _X , A ' _Y , 0), at this time, the acceleration vector after rotation Will fall on the plane formed by the XY axis, and the calculation circuit 23 will calculate the acceleration vector The component length |A' _Y | projected on the third coordinate axis (Y axis).

Furthermore, vector rotation circuit 22 will accelerate the vector Rotate around the third coordinate axis (Y axis) to make the acceleration vector The component projected on the XZ plane overlaps the first coordinate axis (Z axis) and forms a new acceleration vector , its position coordinates are (0, A _Y , A ' _Z ), at this time, the acceleration vector after rotation Will fall on the plane formed by the YZ axis, and the calculation circuit 23 will calculate the acceleration vector The component length |A' _Z | projected on the first coordinate axis (Z axis).

Vector rotation circuit 22 will accelerate the vector Then rotate around the second coordinate axis (X axis) (ie, the acceleration vector on the YZ plane) Approaching the Z axis), making the acceleration vector Overlap on the first coordinate axis (Z axis) and form a new acceleration vector , whose position coordinates are (0, 0, A" _Z ), and the calculation circuit 23 calculates the acceleration vector A third angle ψ of the independent coordinate system ( φ , θ , ψ ) is obtained by rotating to an angle overlapping the first coordinate axis (Z-axis).

Thus, the acceleration sensor 20 uses the "vector rotation" method to measure the acceleration vector it senses. Convert from the Cartesian coordinate system (X, Y, Z) to an independent coordinate system ( φ , θ , ψ ) to see the angular change of the patient's head posture. Of course, the acceleration sensor 20 can also utilize other calculation methods. For example, the acceleration sensor 20 can cooperate with a computer (not shown) to measure the detected acceleration vector. The image is converted to the computer for coordinate conversion, and the conversion result is transmitted back to the acceleration sensor 20, so that the angle of the patient's head posture can be also known, so it is not limited to this embodiment.

Since the acceleration sensor 20 can sense the angle of the patient's head, the posture, angle, and the like of the head during sleep can be known. Therefore, the processing module 30 receives the angle sensed by the acceleration sensor 20, and the subtraction circuit 32 subtracts the angle from the ideal angle stored in the storage circuit 31 in advance, thereby calculating the relationship between the two. The offset is used to determine the difference between the patient's current head posture and the ideal head posture, so as to monitor the patient's head posture during sleep, and the correction circuit 33 calculates the offset according to the offset. A correction amount for adjusting the angle of the patient's head is transmitted, and the correction amount is transmitted to the pump control module 40. In particular, the processing module 30 and the acceleration sensor 20 can be mutually transmitted by wire or wirelessly, and is not limited in any way.

The warning unit 50, the processing module 30 further includes a timing circuit 34 coupled to the control circuit 35. The warning unit 50 is a buzzer, which is preferably disposed in the airbag unit 10, but may also be a Independent component. When the correction circuit 33 determines that the offset calculated by the subtraction circuit 32 is not zero (or is less than a predetermined range), indicating that the patient's affected part posture is not the ideal posture, the timing circuit 34 starts timing, if a period of time is passed After the time, the offset is still not zero, which means that the patient's affected part can't adjust to the ideal angle to achieve the natural relief of discomfort or pain. At this time, the correction circuit 33 will drive the warning unit 50 to send a warning signal (ie, sound). To wake up patients or surrounding caregivers and their families. It is to be noted that the warning unit 50 can also be a light-emitting diode (LED) or a display, so that when the patient's affected part cannot be adjusted to the ideal posture to achieve natural comfort of discomfort or pain, the correction circuit 33 also The LED can be driven to illuminate, flash, or drive the display to display a warning screen, so it is not limited to the buzzer.

In addition, the human body part posture monitoring and adjustment system 100 can further include a transmission module 60 and a host device 70 coupled to the transmission module 60. The transmission module 60 is used for the acceleration sensor 20 and the processing module. The detected or processed data is transmitted to the host device 70, so that the host device 70 can further analyze and count the data for remote care purposes. The transmission module 60 is formed on the same wafer as the processing module 30 and coupled to the correction circuit 33. However, the transmission module 60 may be formed on the same wafer as the acceleration sensor 20, and is not limited to this embodiment.

And convert it into a corner and inclination ( φ , θ , ψ ) corresponding to the posture of the affected part of the patient.

In step S20, the subtraction circuit 32 subtracts the angle output by the acceleration sensor 20 from an ideal angle to calculate an offset between the two.

In step S30, the correction circuit 33 determines whether the offset is zero (or less than a predetermined range), and if so, if the patient's affected part posture is an ideal posture, step S10 is repeatedly performed to continuously monitor the head posture; Otherwise, step S40 is performed.

In step S40, the correction circuit 33 determines whether the timer circuit 34 is timed to a preset time (that is, whether the time when the offset is not zero reaches a preset time), and if not, it indicates that the patient's current affected part posture is not The ideal posture, but the time is not long, the patient has no immediate danger, so step S50 is performed.

In step S50, the correction circuit 33 calculates a correction amount for adjusting the angle of the affected part of the patient according to the offset amount, and transmits the correction amount to the pump control module 40, so that the pump control module 40 performs step S60. .

In step S60, the pump control module 40 controls the charging and discharging of the inflating pump 11 in the airbag unit 10 according to the correction amount to adjust the posture of the affected part of the patient, and after adjusting the airbag unit 10, step S10 is repeatedly performed to Continue to detect the patient's head posture.

In step S40, if the timing circuit 34 counts up to or exceeds the preset time, it indicates that the posture of the affected part of the patient has not been adjusted to a desired posture after a period of adjustment, and the natural posture of the discomfort or pain is corrected. The circuit 33 performs step S70 to drive the warning unit 50 to emit an audible signal to The patient or the surrounding caregivers and their families are alerted, or the relevant data is transmitted to the host device 70 through the transmission module 60 to immediately notify the remote medical staff to achieve the effect of the remote care.

In addition, the control circuit 35 can also control the transmission module 60 to instantly transmit the angle data sensed by the acceleration sensor 20 (eg, the angular offset, the adjustment amount of the adjustment head, etc.) to the host device 70 for the host. The device 70 performs subsequent analysis, storage, and the like. For example, referring to FIG. 8, the host device 70 can be a sleep multiple physiological examination (PSG) device, and the human body posture monitoring and adjustment system 100 can include the posture recognition for increasing the patient's rotation during sleep. A plurality of acceleration sensors 20 respectively mounted on the head and the trunk of the patient to monitor the electrocardiogram (ECG), myoelectric signal (EMG), and eye movement (EOG) data of the PSG device. The posture real-time monitoring and adjustment system 100 can simultaneously provide rotational changes to the torso and head.

In the embodiment of FIG. 8, the transmission module 60 is electrically connected to a predetermined analog port (not shown) in the PSG device, and the control circuit 35 includes a digital analog converter (DAC, not shown).
