[0027] Further, such as Figure 6 As shown, an elastic band 33 is provided on the arc plate 15 .

[0028] Further, such as Figure 3-5 As shown, a through hole 21 is provided in the middle of the sandbag 20 , an air bag 22 is provided in the through hole 21 , a pressing ball 24 is provided below the air bag 22 , and a connecting pipe 25 is provided to connect the interior of the pressing ball 24 and the interior of the air bag 22 .

[0029] Further, such as Figure 3-5 As shown, a first one-way valve 26 is provided at the lower side of the pressing ball 24 , a second one-way valve 27 is provided at the connection between the connecting tube 25 and the airbag 22 , and a deflation valve 28 is provided at one side of the airbag 22 .

[0030] Further, such as Figure 1 As shown, two moving rods 30 are slidably provided at one end of the thigh support frame 11 , and a supporting foot 29 is fixedly provided at one end of each moving rod 30 which is away from the direction of the thigh support frame 11 .

[0032] When in use, the staff places the Brownian traction frame on the bed so that the thigh support frame 11 faces the patient's legs; then, the staff pulls the elastic belt 33 to place the patient's lower limbs into the arc plate 15, and the staff loosens the elastic belt 33, thereby limiting the patient's lower limbs in the arc plate 15 through the elastic belt 33.

[0033] Secondly, the staff places the traction rope on the weight on the first roller 36 and the second roller 37, and then buckles the hanging rod on the traction rope on the bandage of the patient's lower limbs, so as to pull the patient's lower limbs through the weight and the traction assembly, so as to achieve the purpose of correcting fractures, dislocations, maintaining the position after reduction or correcting joint deformities, and relieving muscle spasms and pain.

[0034] The patient's lower limbs are placed in an inclined state by traction of heavy objects. At this time, the patient's calves are located in the arc plate 15, and the patient's thighs are located on the upper side of the second supporting cloth 14, so that the patient's thighs squeeze the thigh support frame 11, so that the thigh support frame 11 rotates, and the rotation of the thigh support frame 11 drives the arc plate 15 to rotate through the connecting plate 17, so that the arc plate 15 and the thigh support frame 11 are kept in the same straight line, so that the patient's thighs are supported by the second supporting cloth 14, and the patient's calves are limited by the arc plate 15, so as to avoid the patient's lower limbs from being suspended in the air and prevent the patient's lower limbs from displacement and sliding. Next, the staff presses the pressing ball 24, so that the air in the pressing ball 24 enters the airbag 22 through the connecting tube 25; the staff repeatedly presses the pressing ball 24, and at this time, when the staff releases the pressing ball 24, the air outside the pressing ball 24 enters the pressing ball 24 through the first one-way valve 26, and when the staff presses the pressing ball 24, the air in the pressing ball 24 enters the airbag 22 through the connecting tube 25 and the second one-way valve 27, thereby inflating the airbag 22; the expansion of the airbag 22 is limited and guided by the through port 21, so that the airbag 22 can only expand upward, thereby supporting the lower side of the arc plate 15 through the airbag 22, thereby improving the comfort of the patient's lower limbs.

[0035] Finally, the staff rotates the two bolts 31 so that the two bolts 31 disengage from the two slots 32 respectively, so that the two moving rods 30 can slide in one end of the thigh support frame 11, so as to adjust the distance between the thigh support frame 11 and the two supporting feet 29, so that the supporting feet 29 are tilted and moved downward to contact the bed; at this time, the staff rotates the two bolts 31 so that one end of the two bolts 31 enters the corresponding two slots 32 respectively, so that the moving rod 30 is limited and fixed in the thigh support frame 11 through the cooperation of one end of the bolt 31 and the slot 32, so that the patient's thigh is supported by the two supporting feet 29, the two moving rods 30 and the thigh support frame 11 in cooperation with the second supporting cloth 14, thereby improving the stability of the patient's lower limbs.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
