Thereby can adjust patient's head to suitable angle according to the relation of healthy side of patient and sick side when carrying out skin flap transplantation operation back patient and being in the state of lying, avoid causing the tractive to the skin flap, guarantee that patient's blood circulation is normal. Solves the problem that the head of a patient can not be adjusted to a proper angle according to the specific operation condition of the patient when the patient is in a horizontal state after the skin flap transplantation operation in the prior art.
In particular, the first and second diaphragms inside the main airbag 10 are crossed. Under normal conditions, the air pressure of the first air bag 11 and the air pressure of the second air bag 12 are larger than that of the third air bag 13 and that of the fourth air bag 14, the height of the first supporting area is larger than that of the second supporting area, when a patient lies down and the head of the patient is rested on the main air bag 10, the head of the patient slightly leans forward, the head of the patient is in a chest-containing position, and the patient can effectively avoid the traction of the skin flaps for the bilateral skin flap transfer patient, so that the blood circulation is ensured. For a single-side flap transplantation patient, when the patient lies down and the head is rested on the main air bag 10, if the affected side of the patient is positioned at one side close to the third supporting region, the air pressure of the first air bag 11 and the second air bag 12 is ensured to be greater than that of the third air bag 13 and the fourth air bag 14, the air pressure of the fourth air bag 14 is adjusted to be greater than that of the third air bag 13, the height of the fourth supporting region is greater than that of the third supporting region, and the head of the patient is slightly deflected to one side of the third air bag 13 while keeping the chest-containing position, namely the head of the patient is inclined to the affected side, so that the traction on the flap is further reduced; on the contrary, if the affected side of the patient is located at the side close to the fourth support region, while ensuring that the air pressures of the first air cell 11 and the second air cell 12 are greater than those of the third air cell 13 and the fourth air cell 14, the air pressure of the third air cell 13 is adjusted to be greater than that of the fourth air cell 14, so that the height of the third support region is greater than that of the fourth support region, and the head of the patient is slightly deflected to the side of the fourth air cell 14, that is, the head of the patient is inclined to the affected side while maintaining the chest-containing position, thereby further reducing the pulling of the flap.
In addition, in order to enable the head of the patient to be further inclined forwards and maintain the chest containing position, the transition part between the third air bag 13 and the fourth air bag 14 is provided with an arc-shaped concave part to adapt to the shape of the neck of the patient, so that the supporting height of the neck is reduced as much as possible, the head of the patient is inclined forwards, and the pulling of a flap is reduced.
Further, as shown in fig. 2, the air pressure adjusting part 20 includes a main air inlet pipe 21, a five-way electromagnetic valve 23, a branch air inlet pipe 24, a one-way valve 25, a controller 26, a pressure relief valve 27, and a pressure sensor 28, a first end of the main air inlet pipe 21 has an air charging port 22, and the air charging port 22 is used for connecting with an air pump; the five-way electromagnetic valve 23 is positioned at the connection position among the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14, the five-way electromagnetic valve 23 is provided with an air inlet port and four air outlet ports, and the second port of the main air inlet pipe 21 is communicated with the air inlet port of the five-way electromagnetic valve 23; the number of the branch air inlet pipes 24 is four, first ports of the four branch air inlet pipes 24 are correspondingly communicated with four air outlet ports of the five-way electromagnetic valve 23, second ports of the four branch air inlet pipes 24 correspondingly extend to the interiors of the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14, air flow generated when the air pump works is allocated through the five-way electromagnetic valve 23, and the air inlet ports and the corresponding air outlet ports of the five-way electromagnetic valve 23 are opened to inflate the corresponding air bags so as to increase air pressure of the air bags.
The controller 26 is connected to the five-way solenoid valve 23, and the controller 26 is configured to control opening and closing of the air inlet port and each air outlet port of the five-way solenoid valve 23 according to the air pressure values in the first air bag 11, the second air bag 12, the third air bag 13, and the fourth air bag 14, so as to control air pressure adjustment of each air bag.
Four check valves 25 are provided, and four check valves 25 are correspondingly provided at second ports of the four branched intake pipes 24 to inflate the first, second, third, and fourth airbags 11, 12, 13, and 14 through the four check valves 25. The check valve 25 functions to prevent the reverse flow of the air stream.
The number of the pressure relief valves 27 is four, 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; the controller 26 is further configured to control the four pressure relief valves 27 to open or close according to the air pressure values in the first air bag 11, the second air bag 12, the third air bag 13, and the fourth air bag 14, and when the pressure relief valves 27 are opened, the corresponding air bags can be relieved of pressure, so that the pressure of the air bags is reduced.
The number of the pressure sensors 28 is also four, and the 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 connected with the controller 26; the four pressure sensors 28 are used for monitoring the internal air pressures of the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14 and sending the monitored air pressure values to the controller 26.
When the five-way electromagnetic valve is used specifically, the air pressure values of the first air bag 11, the second air bag 12, the third air bag 13 and the fourth air bag 14 are set in advance through the controller 26 according to the specific conditions of a patient, then the air bags are inflated by connecting the air pump, and when the pressure sensor 28 in each air bag monitors that the pressure of the corresponding air bag reaches a set value, the controller 26 controls the corresponding air outlet port of the five-way electromagnetic valve 23 to be closed. When the pressure of all the air bags 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 is removed for use.
In the use process, if the air pressure of any air bag is too high, the head of the patient cannot be adjusted to an appropriate angle, and the controller 26 can control the pressure release valve 27 of the corresponding air bag to open for pressure release. When the height of the air bag is adjusted to a suitable height, the relief valve 27 is closed.
In use, the patient is prevented from bending back the head or deflecting the head away from the affected side in a sleeping state or a restless state to cause a pulling on the flap. Further, the fixed headrest structure further comprises an alarm 30, and the alarm 30 is connected with the controller 26; for the patient with bilateral flap transfer, in a normal state, when the air pressure of the first air bag 11 and the second air bag 12 is greater than that of the third air bag 13 and the fourth air bag 14, the height of the first support area is greater than that of the second support area, so that the head of the patient slightly leans forward, and the head is in a chest-containing position. If the head of the patient leans backwards, the upper end of the head presses the first air bag 11 and the second air bag 12, meanwhile, the neck part relieves the pressing of the third air bag 13 and the fourth air bag 14, so that the pressure of the first air bag 11 and the second air bag 12 is increased, the pressure of the third air bag 13 and the fourth air bag 14 is reduced, the maximum value of the air pressure of the first air bag 11 and the second air bag 12 and the minimum value of the air pressure of the third air bag 13 and the fourth air bag 14 are set by the controller 26 in advance, when the pressure sensors 28 in the first air bag 11 and the second air bag 12 monitor that the internal air pressure value is greater than the set maximum value and/or when the pressure sensors 28 in the third air bag 13 and the fourth air bag 14 monitor that the internal air pressure value is less than the set minimum value, namely, the head of the patient is indicated to lean backwards, the controller 26 sends an alarm instruction to the alarm 30 to drive the alarm 30, thereby reminding the patient to adjust the head posture and simultaneously reminding the medical care personnel to treat the patient as soon as possible.
For a unilateral skin flap transplantation patient, in a normal state, the air pressure of the two air bags close to the affected side should be smaller than the air pressure of the two air bags close to the healthy side, namely the height of the two air bags on the affected side is smaller than that of the two air bags on the healthy side, so that the head of the patient deflects to the affected side to relieve the traction of the skin flap. If the patient is deflected to the healthy side in a sleeping state or a restless state, the two air bags close to the healthy side are pressed, and the pressing of the two air bags close to the affected side is reduced, so that the air pressure of the two air bags close to the healthy side is increased, and the air pressure of the two air bags close to the affected side is reduced. Similarly, the controller 26 sets the minimum value of the two air bags close to the affected side and the maximum value of the two air bags close to the affected side in advance, when the pressure sensors 28 in the two air bags at the affected side monitor that the internal air pressure value is greater than the set maximum value and/or the pressure sensors 28 in the two air bags at the affected side monitor that the internal air pressure value is less than the set minimum value, the head of the patient is shown to deflect towards the affected side, the controller 26 sends an alarm instruction to the alarm 30 to drive the alarm 30 to send out an alarm signal, so that the patient is reminded to adjust the posture of the head, and meanwhile, medical staff can be reminded to treat the patient as soon.
In order to assist in fixing the head of the patient in the upright position, as shown in fig. 4 and 5, the headrest structure further includes a first strap 40 and a second strap 50, the main airbag 10 is padded at the rear end of the head of the patient when the patient is in the upright position, the first strap 40 and the second strap 50 are both two, the first ends of the two first straps 40 are connected to the lower end of the main airbag 10, and the second ends of the two first straps 40 are passed around the armpits of the patient and are tied together in front of the chest of the patient to fix the lower end of the main airbag 10. First ends of two second straps 50 are connected to the upper end of the main airbag 10, and second ends of the two second straps 50 are tied to the two first straps 40 to pull the upper end of the main airbag 10, so that the first airbag 11 and the second airbag 12 apply forward thrust to the rear side of the patient's head to tilt the patient's head forward, thereby reducing the pulling of the flap. Two second straps 50 are placed on either side of the patient's head after being fastened.
In addition, when the head of a patient needs to be rotated in an upright position for bilateral flap transfer, the patient needs to be connected with the body to rotate together, so that the flap is prevented from being pulled. In contrast, two side airbags 60 are further arranged on two sides of the main airbag 10, third straps 61 are respectively arranged at the end portions of the two side airbags 60, and after the main airbag 10 is fixed by a patient in an upright position, the two third straps 61 are correspondingly bonded to the two second straps 50, so that the head of the patient is prevented from rotating independently by fixing the two side airbags 60 at the neck of the left side and the right side of the patient, and the skin flap is prevented from being pulled.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
