In the invention, as shown in fig. 1 and 4 in an initial state, the second flow through groove 18 is positioned between the two first flow through grooves 17, the second flow through groove 18 is blocked, when the invention is used, a patient sits on the seat, the patient is positioned in the middle of the lifting plate 3, the lifting plate 3 is pressed down under the action of the self gravity of the patient, the first elastic air bag 5 and the return spring 4 are compressed, the air in the first elastic air bag 5 enters the second elastic air bag 6 through the first communication pipe 7, meanwhile, the two third elastic air bags 15 are simultaneously compressed, the compression acting forces applied to the two third elastic air bags 15 are basically the same, the two third elastic air bags 15 are simultaneously compressed to an equivalent state, the air in the two third elastic air bags 15 enters the horizontal groove 13 through the corresponding second communication pipe 16, under the action of air pressure, the first sliding block 11 and the second sliding block 12 synchronously move, the first sliding block 11 and the second sliding block 12 are equivalent, the notch of the second flow through groove 18 is always dislocated with the notches of the two first flow through grooves 17, the second flow through groove 18 is always blocked, the third sliding block 18 is also blocked, the second elastic air bag 6 can not be rapidly discharged outside;
in the subsequent traction process, if the spine of the patient is bent laterally, the gravity center of the patient is changed, the lateral bending is more serious, the gravity change is more obvious, when the gravity center is changed, the compression action on the two third elastic air bags 15 is increased by one and reduced by the other, the motion amount of the first sliding block 11 and the second sliding block 12 is different, no matter the gravity center is deviated to the left side or the right side, as long as the central deviation amount is greater than a preset value, one first flow through groove 17 is in direct conduction with the second flow through groove 18, high-pressure air in the second elastic air bag 6 is discharged through the corresponding whistle body 20, so that a warning sound is given out to remind the patient to correct the sitting posture, and after the traction is finished, after the patient leaves the lifting plate 3, the external air is supplemented into the first elastic air bag 5 through the air inlet pipe 8 to be used next time;
meanwhile, when the first elastic air bag 5 is compressed, the gas in the first elastic air bag 5 enters the fourth elastic air bag 31 through the fourth communicating pipe 32, the fourth elastic air bag 31 expands and pushes the abutting block 33 to extend out of the chute 30, the abutting block 33 protrudes into the placing groove 28 and extrudes the traction wire 29, so that the traction wire 29 is partially bent and serves as the elastic margin of the traction wire 29, therefore, in the traction process, if a patient moves or suddenly lowers the head, when the traction wire 29 is suddenly stretched downwards, the traction wire 29 drives the abutting block 33 to abut against the fourth elastic air bag 31, the traction wire 29 can be buffered by utilizing the elastic force of the fourth elastic air bag 31, and therefore, the damage caused by over-traction of the patient is avoided, and compared with the traditional isometric traction, the safety is higher;
during traction, firstly, the skull ring body 34 is fixedly sleeved on the head of a patient, the structure and the working principle of the skull ring body 34 are the prior art, so detailed description is omitted, then the winding roller 25 is rotated through the rotary disc 24 and the rotary rod 23 to roll the traction wire 29, the traction wire 29 is continuously wound on the winding roller 25, so that the head of the patient can be dragged, the traction force can be obtained through the spring scale, the head of the patient is communicated with the patient in the traction process, the traction force is moderate, if headache, neck pain, numbness of the two upper limbs and the like occur, the traction is immediately stopped, the display reading of the spring scale is recorded, the traction force is adjusted every day, the patient does not experience discomfort, the limiting rod 27 is inserted into the corresponding through hole 26 and the limiting groove, so that the winding roller 25 can be fixed, the stability of the traction force is kept, in the invention, a traction weight group is removed, the traction wire 29 is used for traction at the rear part of a wheelchair, so that the adjustment of the traction force is changed into a flexible and stable change, the increase and decrease of the force are more accurate and free;
after traction is finished, the patient unloads the head skull ring body 34 and separates from the lifting plate 3, redundant gas in the second elastic air bag 6 flows back to the first elastic air bag 5 through the first communication pipe 7, and the two third elastic air bags 15 recover to be used next time.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
