The working principle is as follows: in the using process, when a patient lies down, the threaded rod 21 rotates to drive the clamping plate 22 to move, the clamping plate 22 moves to drive the elastic membrane 23 to move, so that the elastic membrane 23 can move to a proper position, then an operator starts the air pump 25, and after the air pump 25 is started, air is introduced into the air cavity 24 through the air pipe 26, so that the elastic membrane 23 deforms and contacts with the head of the patient, the head of the patient can be fixed, and the situation that the head of the patient rotates to cause secondary injury to a wound when the patient has a rest after a craniocerebral operation is avoided;

when the air pressure value inside the air cavity 24 is greater than the deformation force value of the first spring 273, the high air pressure inside the air cavity 24 can push the sealing block 272 to move, the first spring 273 can be compressed in the moving process of the sealing block 272, when the sealing block 272 moves to a certain position, the connecting cavity 271 is communicated with the air guide groove 274, at the moment, the high-pressure air of the air cavity 24 can enter the air guide groove 274 from the connecting cavity 271 and enter the air exhaust groove 2710 from the air guide groove 274, and under the action of the resilience force of the first spring 273, the air inside the air cavity 24 can enter the air guide groove 274 only when the air pressure inside the air cavity 24 reaches a certain value, so that under the continuous work of the air pump 25, the air pressure inside the air cavity 24 can be kept in a certain range and can be introduced into the air guide groove 274;

when gas is discharged from the inside of the gas guide groove 274 and enters the inside of the gas discharge groove 2710, the flow of the gas can drive the impeller 275 to rotate, the stay cord 276 can be intermittently pulled in the rotation process of the impeller 275, when the stay cord 276 is pulled, the stay cord 276 can drive the reel 278 to rotate, the reel 278 rotates to drive the guide plate 277 to rotate, the reel 278 rotates to drive the spring II 279 to twist and compress, when the stay cord 276 is not pulled any more, under the action of resilience force of the spring II 279, the reel 278 reversely rotates and drives the guide plate 277 to reversely rotate, so that the guide plate 277 can continuously swing back and forth, the flow direction of the gas discharged from the gas discharge groove 2710 can be continuously adjusted, the range which can be blown after the gas is discharged is wider, and the head of a patient can be better cooled;

when the device is used, an operator can adjust the position heights of the two sliding plates 32 by pulling the two sliding plates 32 according to the actual wound position of a patient, so that the support belt 34 can stably support the head of the patient, then the operator energizes the electromagnet 362, magnetism generated after the electromagnet 362 is energized is mutually attracted with the fixed rod 364 and drives the fixed rod 364 to move and exit from the inside of the fixed hole 365, so that the rotation of the wind-up roller 33 is not limited, at the moment, the operator pulls the support belt 34 according to the actual position of the wound on the head of the patient, so that the position of the ventilation opening 35 moves to meet the requirement of lying of the patient, when the support belt 34 is pulled, the spring four 366, close to one end of the ventilation opening 35, can rotate under the effect of resilience force to drive the wind-up roller 33 on the side to wind up the loosened support belt 34, and the spring four 366, far away from one end of the ventilation opening 35, continues to be twisted and compressed and drives the wind-up roller 33 on the side to rotate to place the support belt 34 outside, thereby make ventilative mouthful 35 position control can normally go on, just so make the position of supporting area 34 and ventilative mouthful 35 position all can adjust according to patient's actual conditions, thereby can avoid the patient to receive the condition emergence of injury once more at the in-process wound part of lying, also improved the functional of fixer simultaneously greatly, can satisfy the needs of in-service use condition.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
