[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments: A restraint device for preventing lower limb thrombosis includes: a medical bed 1; support frames 2 are fixedly connected to both sides of the bottom of the medical bed 1; a fixed box 3 is fixedly connected inside the medical bed 1; a rotating disk 4 is provided at each of the four corners of the top of the fixed box 3; a first rotating shaft 5 is fixedly connected to the center of the bottom of each rotating disk 4; the first rotating shaft 5 is rotatably connected to the fixed box 3; an adjustment mechanism 6 for restraining the patient's lower limbs is provided on one side of the rotating disk 4; a linkage mechanism 7 for controlling massage balls 24 to massage the muscles of the patient's lower limbs is provided inside the fixed box 3. When the patient lies flat on the medical bed 1, medical staff restrain the patient's lower limbs through the adjustment mechanism 6, and then control the first rotating shaft 5 to rotate through the linkage mechanism 7. As the first rotating shaft 5 rotates, it drives the rotating disk 4, thereby continuously squeezing and massaging the muscles of the patient's lower limbs.

[0018] like Figure 4 and Figure 5As shown, the adjustment mechanism 6 includes: a first restraining strap 8 is provided on one side of the rotating disk 4, and a second restraining strap 9 is provided on the side of the rotating disk 4 away from the first restraining strap 8. The bottom ends of the first restraining strap 8 and the second restraining strap 9 are fixedly connected to the fixed box 3; an adjustment buckle 10 is fixedly connected to the end of the second restraining strap 9 away from the fixed box 3, and a slot 11 is provided on the top of the adjustment buckle 10. An elastic sheet 12 is provided inside the slot 11, and one end of the elastic sheet 12 is fixedly connected to the adjustment buckle 10. A buckle 13 is fixedly connected to the bottom of the elastic sheet 12 away from the adjustment buckle 10, and a fixing plate 14 is fixedly connected to the top of the elastic sheet 12 near the buckle 13. The end of the first restraining strap 8 away from the fixed box 3 passes through the adjustment buckle 10 and extends to the outside of the adjustment buckle 10. A set of evenly distributed... Several slots 15 are provided, which are adapted to buckles 13. Medical staff place the patient's lower limb between the first restraint belt 8 and the second restraint belt 9, then insert the top of the first restraint belt 8 into the adjusting buckle 10 and pull the first restraint belt 8, so that the space between the first restraint belt 8 and the second restraint belt 9 is continuously reduced, so that the first restraint belt 8 and the second restraint belt 9 fit against the surface of the patient's lower limb. After adjustment, the elastic sheet 12 drives the buckle 13 to engage with the slot 15 on the first restraint belt 8, thereby restraining the patient's lower limb. When it is necessary to loosen the patient's lower limb, push the fixing plate 14. The fixing plate 14 drives one end of the elastic sheet 12, causing the elastic sheet 12 to bend. As the elastic sheet 12 bends, it causes the buckle 13 to separate from the slot 15, so that the first restraint belt 8 can be pulled out from the adjusting buckle 10.

[0019] like Figure 4 As shown, sponge pads 16 are provided on the inner walls of the first restraint belt 8 and the second restraint belt 9, respectively. The sponge pads 16 are fixedly connected to the first restraint belt 8 and the second restraint belt 9, which improves the comfort of the patient's lower limbs when the first restraint belt 8 and the second restraint belt 9 are used to restrain them.

[0020] like Figure 3As shown, the linkage mechanism 7 includes: a dual-axis motor 17 fixedly connected inside the fixed housing 3; a second rotating shaft 18 fixedly connected to both output ends of the dual-axis motor 17; a worm gear 19 fixedly connected to the outer surface of the middle part of the second rotating shaft 18; worm wheels 20 meshing on both sides of the worm gear 19; a third rotating shaft 21 fixedly connected to the center of each worm wheel 20; and both ends of the third rotating shaft 21 rotatably connected to the fixed housing 3. A first gear 22 is provided on the top of each worm wheel 20, and the first gear 22 is fixed to the outer surface of the third rotating shaft 21. The outer surface of the first rotating shaft 5 near the first gear 22 is also fixedly connected to the third rotating shaft 21. A second gear 23 is fixedly connected and meshes with the first gear 22. When the dual-axis motor 17 is started, the output ends on both sides of the dual-axis motor 17 drive the second rotating shaft 18. The second rotating shaft 18 drives the worm gear 19 to rotate. While the worm gear 19 rotates, it drives the worm wheels 20 on both sides. While the worm wheels 20 rotate, they drive the second rotating shaft 18. While the second rotating shaft 18 rotates, it drives the first gear 22. The first gear 22 drives the second gear 23. While the second gear 23 rotates, it drives the first rotating shaft 5. While the first rotating shaft 5 rotates, it drives the rotating disk 4 to rotate.

[0021] like Figure 3 As shown, each of the rotating discs 4 has three massage balls 24 on its top. The massage balls 24 are fixedly connected to the rotating discs 4. As the rotating discs 4 rotate, they drive the massage balls 24 on the top to rotate, thereby continuously squeezing and massaging the muscles of the patient's lower limbs.

[0022] like Figure 1 As shown, a control box 25 with an internal touch screen is provided on one side of the medical bed 1. The control box 25 is fixedly connected to the medical bed 1, making it convenient for medical staff to operate the device.

[0023] like Figure 1 and Figure 2 As shown, the bottom of the support frame 2 is fixedly connected with anti-slip pads 26, which improves the stability of the device and prevents the device from shifting.

[0024] Working principle: The patient lies flat on the medical bed 1. Medical staff place the patient's lower limbs between the first restraint strap 8 and the second restraint strap 9. The tip of the first restraint strap 8 is then inserted into the adjusting buckle 10, and the first restraint strap 8 is pulled, causing the space between the first restraint strap 8 and the second restraint strap 9 to gradually decrease, bringing them into contact with the surface of the patient's lower limbs. After adjustment, the elastic sheet 12 drives the buckle 13 to engage with the slot 15 on the first restraint strap 8, thus restraining the patient's lower limbs. Finally, the dual-axis motor 17 is activated. The output ends of the dual-axis motor 17 drive the second rotating shaft 18, which in turn drives the worm gear 19 to rotate. Simultaneously, the worm gear 19 rotates, driving the worm wheels 20 on both sides. The worm wheels 20 rotate, driving the second rotating shaft 18, which in turn drives the first gear 22. The first gear 22 drives the second gear 23, which in turn drives the second gear 23. The first rotating shaft 5 rotates while simultaneously driving the rotating disk 4 to rotate. The rotating disk 4, in turn, drives the massage ball 24 at the top to rotate, thus continuously squeezing and massaging the muscles of the patient's lower limbs. This continuous squeezing and massaging of the lower limbs of agitated patients promotes blood flow, reduces the workload of medical staff, and solves the problem of the existing practice of requiring medical staff to periodically loosen the limbs of agitated patients during long-term restraint to promote blood flow and prevent lower limb thrombosis, which increases the workload of medical staff and raises concerns about attacks on medical staff during limb loosening activities. After the massage is completed, the fixing plate 14 is pushed, causing one end of the elastic sheet 12 to bend. Simultaneously, the bending of the elastic sheet 12 causes the buckle 13 to separate from the slot 15, allowing the first restraint strap 8 to be pulled out from the adjusting buckle 10.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
