The first end of air tube 21 has inflation port 22, and inflation port 22 is used for being connected with air pump; , the five-way electromagnetic valve 23 has an air intake port and four air outlet ports, and the second port of the main air intake pipe 21 communicates with the air intake port of the five-way electromagnetic valve 23; the branch air intake pipes 24 are four, and the four branch air intake pipes 24 The first ports of the five-way solenoid valve 23 correspond to the four outlet ports, and the second ports of the four branch air inlet pipes 24 extend to the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14. Inside the air pump, the airflow generated when the air pump is working is adjusted through the five-way solenoid valve 23, and the air inlet port and the corresponding air outlet port of the five-way solenoid valve 23 are opened to inflate the corresponding airbag to increase the air pressure of the airbag.

The controller 26 is connected with the five-way solenoid valve 23, and the controller 26 is used to control the intake ports of the five-way solenoid valve 23 according to the air pressure values in the first airbag 11, the second airbag 12, the third airbag 13 and the fourth airbag 14. and the opening and closing of each air outlet port, so as to control the air pressure adjustment of each air bag.

There are four one-way valves 25, and four one-way valves 25 are correspondingly arranged on the second ports of the four branch intake pipes 24, so as to pass through the four one-way valves 25 to the first air bag 11, the second air bag 12, and the third air bag. 13 and the fourth air bag 14 is inflated. The one-way valve 25 plays a role in preventing the reverse flow of the air flow.

There are four pressure relief valves 27, and the four pressure relief valves 27 are correspondingly arranged on the side walls of the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14 and are connected with the controller 26; wherein, the control The device 26 is also used to control the opening or closing of four pressure relief valves 27 according to the air pressure values in the first airbag 11, the second airbag 12, the third airbag 13 and the fourth airbag 14. When the pressure relief valve 27 is opened, the corresponding The bladder is depressurized, thereby reducing the pressure of the bladder.

There are also four pressure sensors 28, and four pressure sensors 28 are correspondingly arranged in the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14 and are all connected with the controller 26; wherein, the four pressure sensors 28 is used to monitor the internal air pressure of the first air bag 11 , the second air bag 12 , the third air bag 13 and the fourth air bag 14 and send the monitored air pressure values to the controller 26 .

In specific use, the air pressure values of the first airbag 11, the second airbag 12, the third airbag 13 and the fourth airbag 14 are set through the controller 26 in advance according to the specific conditions of the patient, and then the air pump is connected to inflate each airbag. When the pressure sensor 28 in the airbag detects that the pressure of the corresponding airbag reaches the set value, the controller 26 controls the corresponding air outlet port of the five-way solenoid valve 23 to close. When the pressure of all the airbags reaches the set value, the controller 26 controls all the air outlet ports and the air inlet ports of the five-way electromagnetic valve 23 to be closed, and then the air pump can be removed for use.

During use, if the air pressure of any airbag is too high to adjust the patient's head to an appropriate angle, the controller 26 can control the pressure relief valve 27 of the corresponding airbag to open for pressure relief. When the height of the air bag is adjusted to a suitable height, the pressure relief valve 27 is closed.

During use, in order to prevent the patient from tilting his head back or deflecting his head away from the affected side when he is asleep or agitated, causing the skin flap to be pulled. Further, the fixed headrest structure also includes an alarm 30, which is connected to the controller 26; for patients with bilateral skin flap transfer, under normal conditions, the air pressure of the first airbag 11 and the second airbag 12 is greater than that of the third airbag 13 and the fourth airbag 14, the height of the first support area is greater than the height of the second support area, so that the patient's head is slightly tilted forward, and the head is in a chest position. If the patient's head is tilted backward, the upper end of the head will press the first air bag 11 and the second air bag 12, and the neck position will reduce the compression of the third air bag 13 and the fourth air bag 14, causing the first air bag 11 and the second air bag The pressure of the airbag 12 increases, the pressure of the third airbag 13 and the fourth airbag 14 decreases, and the maximum value of the air pressure of the first airbag 11 and the second airbag 12 and the pressure of the third airbag 13 and the fourth airbag are set by the controller 26 in advance. 14 The minimum value of air pressure, when the pressure sensor 28 in the first air bag 11 and the second air bag 12 monitors that the internal air pressure value is greater than the set maximum value and/or when the pressure sensor in the third air bag 13 and the fourth air bag 14 28 When it is detected that the internal air pressure value is less than the set minimum value, it means that the patient's head is tilted backward, and the controller 26 sends an alarm command to the alarm 30 to drive the alarm 30 to send an alarm signal, thereby reminding the patient to adjust the head posture, At the same time, it can also remind the medical staff to deal with the patient as soon as possible.

For patients with unilateral skin flap transplantation, under normal conditions, the air pressure of the two airbags near the affected side should be smaller than the air pressure of the two airbags near the healthy side, that is, the height of the two airbags on the affected side is smaller than the height of the two airbags on the healthy side, To deflect the patient's head to the affected side and reduce the pulling on the flap. If the patient deflects to the healthy side in the state of sleep or restlessness, it will compress the two air cells near the healthy side and reduce the pressure on the two air cells near the affected side, resulting in an increase in the air pressure of the two air cells near the healthy side High, the air pressure of the two air cells near the affected side is reduced. Similarly, the minimum value of the two airbags near the affected side and the maximum value of the two airbags near the healthy side are set in advance by the controller 26. When the pressure sensors 28 in the two airbags of the healthy side monitor When the pressure sensor 28 in the two airbags on the affected side detects that the internal air pressure value is less than the set minimum value, it indicates that the patient's head deflects to the healthy side, and the controller 26 sends an alarm command to the alarm 30 Drive the alarm 30 to send an alarm signal, thereby reminding the patient to adjust the head posture, and also reminding the medical staff to treat the patient as soon as possible.

In order to assist in fixing the patient's head when the patient is in an upright state, further, as shown in Figure 4 and Figure 5, the fixed headrest structure also includes a first strap 40 and a second strap 50, the main airbag 10 When the patient is in an upright position, it is placed on the rear end of the patient's head. There are two first straps 40 and two second straps 50, and the first ends of the two first straps 40 are connected to the lower end of the main airbag 10. The second ends of the two first straps 40 go around the patient's armpits and are tied together on the patient's chest to fix the lower end of the main airbag 10 . The first ends of the two second straps 50 are connected to the upper end of the main airbag 10, and the second ends of the two second straps 50 are used for binding on the two first straps 40 to pull the main airbag 10. At the upper end, the first airbag 11 and the second airbag 12 apply a forward thrust to the back of the patient's head so that the patient's head is tilted forward to reduce the pulling on the flap. The two second straps 50 are fastened on both sides of the patient's head.

In addition, when patients with bilateral flap transfer need to turn their head in an upright position, they need to rotate together with their body, so as to avoid pulling on the flap. To this end, two side airbags 60 are also arranged on both sides of the main airbag 10, and the ends of the two side airbags 60 are respectively provided with a third strap 61. After the patient fixes the main airbag 10 in the upright position, The two third straps 61 are correspondingly bonded to the two second straps 50 so as to fix the two side airbags 60 on the left and right necks of the patient to prevent the patient's head from turning independently, thereby avoiding pulling on the skin flap .
