[0032] The connection relationship between the restraint member 2 and the restraint seat 1 is:

[0033] With reference to Figure 3 And Figure 4 The upper end face of the restraint seat 1 is provided with a slot 101, and the side face is provided with a mounting hole 102 in communication with the slot 101, and a hole cover is arranged at the hole opening of the mounting hole 102 away from the curved surface.

[0034] The constraint member 2 comprises an outer ring 201, the inner annular surface of the outer ring 201 is provided with an inner air bag 202, the outer annular surface extends radially with a lug 203, the inside of the lug 203 is hollow and communicates with the inner air bag 202, the surface of the lug 203 extends with a plug rod 204, the end of the plug rod 204 is provided with an inclined surface, when the plug rod 204 is inserted into the insertion slot 101, the clamping groove 205 provided on the plug rod 204 is opposite to the mounting hole 102, the distance between the inclined surface and the hole cover decreases from bottom to top.

[0035] The mounting hole 102 is provided with a buckle assembly 5, the buckle assembly 5 comprises a clamping block 501 slidingly installed in the mounting hole 102, all clamping springs 502 between the clamping block 501 and the hole cover, the end of the clamping block 501 extends with a connecting rod 503, the end of the connecting rod 503 passes through the hole cover and is provided with a knob.

[0036] The plug rod 204 is directly inserted into the insertion slot 101, during the insertion process, the inclined surface of the plug rod 204 pushes the clamping block 501 back into the mounting hole 102, when the clamping groove 205 is opposite to the mounting hole 102, the clamping spring 502 releases the elastic force and pushes the clamping block 501 into the clamping groove 205, thereby realizing the connection between the constraint member 2 and the constraint seat 1.

[0037] The clamping block 501 is separated from the clamping groove 205 by actively pulling the connecting rod 503 outward through the knob, thereby canceling the connection between the constraint member 2 and the constraint seat 1.

[0038] The connection relationship between the constraint member 2 and the main pipeline 4 is as follows:

[0039] The upper surface of the main pipeline 4 is provided with an air nozzle 401, the air nozzle 401 and the connecting nozzle 206 are connected through the air pipe 3, it should be noted that the connection between the air nozzle 401 and the air pipe 3 is provided with an electromagnetic valve, when the constraint member 2 is detached from the constraint seat 1, the corresponding electromagnetic valve is closed, and vice versa.

[0040] The side surface of the main pipeline 4 is provided with a side nozzle 402, the side nozzle 402 is connected with an air pump or an air compressor, air is injected into the main pipeline 4 through the air pump, and the air finally enters the inner air bag 202 to make it swell, thereby realizing the constraint of the patient's limbs.

[0041] Preferably, the main pipeline 4 is provided with an air pressure gauge 403; the significance lies in that the air pressure of the main pipeline 4 is equal to the air pressure of the inner air bag 202, therefore, the air pressure of the inner air bag 202 can be monitored through the air pressure gauge 403, thereby indirectly obtaining the constraint degree of the inner air bag 202 to the patient's limbs.

[0042] Preferably, the main pipeline 4 is provided with a pressure relief valve 6, which is used to release pressure when the constraint force of the inner air bag 202 reaches a preset value, so as to avoid that the constraint force is too large to cause the patient's limbs to be uncomfortable.

[0043] Further, referring to Figure 6 , the pressure relief valve 6 comprises a valve shell 601, which is divided into an upper cylindrical section, a middle circular cone section and a lower cylindrical section along an axial line, wherein the lower cylindrical section is connected with the main pipeline 4, the valve shell 601 is provided with a valve core 602, a hollow plate 603 and a valve spring 604 located between the valve core 602 and the hollow plate 603, initially, under the elastic force of the valve spring 604, the valve core 602 has a movement tendency close to the main pipeline 4, so as to tightly fit the middle circular cone section of the valve shell 601 and block it, when the air pressure in the main pipeline 4 is greater than a preset value, the valve core 602 is moved upward to overcome the elastic force of the valve spring 604, the blocking of the valve shell 601 is cancelled, and air can be outputted outward through the valve shell 601 until the air pressure is restored to the preset value, the valve spring 604 immediately releases the elastic force to make the valve core 602 block the valve shell 601 again.

[0044] Further, the valve shell 601 is further provided with an adjusting component 605, which is used to adjust the position of the hollow plate 603, and the significance is that the initial compression amount of the valve spring 604 can be adjusted, so as to adjust the triggering value of the pressure relief valve 6.

[0045] Specifically, the adjusting component 605 comprises a bracket body provided on the upper end of the valve shell 601, the bracket body is provided with a lead screw and a guide sleeve, the upper end of the hollow plate 603 extends a lead screw sleeve and a guide rod, the lead screw is connected with the lead screw sleeve, and the guide rod is slidingly connected with the guide sleeve, the lead screw is rotated through a crank provided on the end of the lead screw, so that the hollow plate 603 can be driven to move and the position of the hollow plate 603 in the valve shell 601 can be changed.

[0046] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, although the present application has been disclosed as above with a preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art, without departing from the technical scheme of the present application, can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not deviate from the technical scheme of the present application, any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application, all still belong to the scope of the technical scheme of the present application.
