[0021] The following Figures 1-4 in conjunction with the attached

[0022] As Figures 1-4 shown, a lumbar traction three-flexion auxiliary pad includes a first bearing section 1 for supporting the waist, a second bearing section 2 for supporting the buttocks, and a third bearing section 3 for supporting the legs. The first bearing section 1 is fixed on the bottom pad, and the second bearing section 2 and the third bearing section 3 are respectively slidably arranged on the bottom pad. That is to say, the first bearing section, the second bearing section, and the third bearing section are arranged in sequence from left to right on the bottom pad. The first bearing section is placed at the waist position, the second bearing section is placed at the buttocks position, and the third bearing section is placed at the leg position. The second bearing section and the third bearing section are movable. Thus, when lifting or lowering the calf, the calf drives the thigh to move, the thigh drives the buttocks to move, and the buttocks drive the waist to move, so as to utilize the three bearing sections to assist the three-flexion movement.

[0023] It should be noted that the overall length of the bottom pad is 3 cm - 7 cm longer than the total lengths of the first bearing section 1, the second bearing section 2, and the third bearing section 3 to limit the moving amplitude of the third bearing section.

[0024] Specifically, as Figure 4 shown, corresponding adjusting members are respectively arranged between the first bearing section 1 and the second bearing section 2 and between the second bearing section 2 and the third bearing section 3 to respectively adjust the positions of the second bearing section 2 and / or the third bearing section 3 on the bottom pad. That is to say, by using the two adjusting members, the second bearing section and / or the third bearing section can be respectively driven to move on the bottom pad.

[0025] Specifically, as Figure 1 and Figure 2 shown, the first bearing section 1 is a lumbar pad bent outward. The upper part of the lumbar pad is an electric inflatable airbag. When in use, air is pumped into the airbag through an air pump, causing the lumbar pad to inflate and support the lumbar region of the patient. The second bearing section 2 is an arc-shaped hip pad recessed inward. Sponge pads are provided on both the lumbar pad and the hip pad. That is to say, both the first bearing section and the second bearing section are designed and shaped according to ergonomics, and sponge pads are provided on the first bearing section and the second bearing section to improve the comfort level of the patient when in use.

[0026] Specifically, as Figures 2-4 shown, the third bearing section 3 includes a support platform 31, a base, and a movable support frame 32. The support platform 31 is fixedly provided on the base. Two groups of movable support frames 32 are symmetrically arranged on both sides of the support platform 31. The end of one group of the movable support frames 32 is lapped with the support plate protruding upward on one side of the base, and the end of the other group of the movable support frames 32 is lapped with the other side of the base. That is to say, the third bearing section is mainly used to bear the legs, that is, the movable support frames respectively arranged on both sides of the support platform. One movable support frame is used to support the thigh, and the other movable support frame is used to support the calf.

[0027] In some embodiments, as Figures 2-4 shown, an equipment cavity is formed between the movable support frame 32, the support platform 31, the support plate, and the base. An adjusting air cylinder 33 for adjusting the tilt angle of the movable support frame is arranged in the equipment cavity. The bottom of the adjusting air cylinder 33 is movably connected to the hinge seat on the base, and the telescopic section of the adjusting air cylinder 33 is movably connected to the hinge seat on the movable support frame. The adjusting air cylinder is electrically connected to the power supply through an external control handle. That is to say, an adjusting air cylinder is arranged in the equipment cavity inside the third bearing section. The adjusting air cylinder is controlled to be energized through an external wired control handle, and the corresponding movable support frame is driven by the adjusting air cylinder to pitch and adjust to simulate the actions of lifting or lowering the thigh or calf.

[0028] Specifically, as Figures 2-4 shown, the adjusting member includes a power part 4 and a reset part 5. The power part 4 is used to drive the second bearing section and / or the third bearing section to slide on the bottom pad, and the reset part 5 is used to drive the second bearing section and / or the third bearing section to return to the original position. The reset part is arranged inside the bottom pad, and the power part is located above the reset part. That is to say, when the adjusting air cylinder drives the movable support frame to pitch and adjust to synchronously drive the thigh or calf to lift or lower, the power part drives the second bearing section and / or the third bearing section to move to synchronously drive the hip to shift, and at the same time, the hip drives the waist to move on the first bearing section, thereby assisting the three-flexion position action.

[0029] In some embodiments, the power unit 4 includes a pushing cylinder. The pushing cylinders are respectively arranged in the first bearing section and the third bearing section. The telescopic end of the pushing cylinder is connected to the second bearing section. The pushing cylinder is electrically connected to the power supply through an external control handle. That is to say, the pushing cylinder is controlled to be energized by an external wired control handle, and the second bearing section and / or the third bearing section are driven to move by the pushing cylinder.

[0030] In some embodiments, the reset unit 5 includes a reset spring. The reset springs are respectively arranged between the first bearing section and the second bearing section and between the second bearing section and the third bearing section. That is to say, the arranged reset springs can help the second bearing section and / or the third bearing section to move smoothly.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
