But may also be used to alter the patient's head and neck orientation and combination orientation by adjusting the adjustment strap 310 on either side, as well as the linear strap 306a.

Example 4:

on the basis of embodiment 3, a mechanism capable of cooling a general anesthesia patient is provided. Referring specifically to fig. 10 and 12, fig. 10 shows a simplified schematic of the mechanism, and fig. 12 shows the specific connection of the components of the mechanism. As can be seen from the figure, the water inflation mechanism connected with each air bag comprises a piston type water vapor compression cylinder 6b. Specifically, the piston type water gas compression cylinder 6b is matched and sleeved with a piston body 605 in a cylindrical cylinder 601, and the rear end of the piston body 605 is connected with a driving part, for example, as shown in fig. 12, the driving part is designed to use a push-pull rod 606 connected to the rear end of the piston body 605, and the piston body 605 is controlled by pushing and pulling the push-pull rod 606 in a linkage manner, so as to drive the piston body to move back and forth in the cylindrical cylinder, and achieve the purpose of sucking gas or sucking ice water.

One side of the front end of the cylinder 601 is connected with a liquid inlet check valve 603 and a liquid inlet stop valve 604 in sequence through a pipeline and then connected with a water outlet at the lower end of the ice water bag 602. The other side of the front end of the cylinder 601 is sequentially connected with an air inlet check valve 608 and an air inlet stop valve 609 through pipelines, wherein the air inlet stop valve 604 and the air inlet stop valve 609 are opened and closed alternately.

It can be seen that the present embodiment not only has the function of controlling the inflation of the air bag, but also has the function of filling ice water into the air bag. Normally, the inlet shutoff valve 604 is closed and the inlet shutoff valve 609 is opened to change the height of the head and neck by controlling the inflation and deflation of the air bag. When the temperature needs to be reduced, the liquid inlet stop valve 604 is opened by closing the air inlet stop valve 609, so that the piston type water vapor compression cylinder 6b can inject ice water into the corresponding air bag to reduce the temperature of a patient. Meanwhile, exhaust valves are respectively arranged on the corresponding air bags, and redundant air in the air bags is exhausted while water is fed. When ice water is used for cooling, the water absorbing layer 9 is usually removed.

Example 5:

on the basis of the embodiment 3, the movable connection mode is that the lower part of the head restraint cover 1 is hinged with the connection part of the neck restraint cover 2. For example, as shown in fig. 1, 3 and 5, a cylinder 106 is transversely disposed on the rear end surface of the head restraint housing 1, and a transverse cylinder groove 107 is disposed on the front end surface of the neck restraint housing 2, which are fitted together and can rotate.

Example 6:

on the basis of the embodiment 3, the movable connection mode is that the lower part of the head restraint cover 1 is hinged with the connection part of the neck restraint cover 2. As shown in fig. 2, 14 and 15, another way of hinging the lower part of the head restraint cover 1 with the neck restraint cover 2 is to provide a connecting ball hole 105 on the rear end face of the head restraint cover and a connecting ball 203 on the front end face of the neck restraint cover 2, and the two are matched and sleeved together.

As can be seen from fig. 2, the pressing paste 309 at the end of the linear belt 306a is formed by combining two magic tapes, in which case, the length of the linear belt 306a at one side can be adjusted rapidly by changing the pasting position, so as to rapidly change the degree of the head and neck deflection to one side.

Example 7:

in addition to embodiment 4, another form of the driving part located at the rear side of the piston type water vapor compression cylinder 6b is that a compression air bag 6c is connected to the rear end of the cylinder 601 through a breathing air pipe 610, as shown in fig. 11. The compression balloon 6c is communicated with a sealing chamber at the rear side of the piston body 605 through a breathing air tube 610, and the compression balloon 6c is pressed to provide a driving force for driving the piston to advance and retreat.

Example 8:

on the basis of embodiment 4, a linkage valve, such as a double-inlet single-outlet reversing valve, can be further adopted as the liquid stop valve 604 and the air inlet stop valve 609.
