Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to an auxiliary support device for patients with lower limb thrombosis. Background Art

[0002] The primary function of a lower extremity venous thrombosis support brace (also known as a lower extremity thrombosis sheath) is to promote lower extremity venous blood circulation by providing moderate pressure, preventing deep vein thrombosis (DVT) and relieving lower extremity swelling. This brace, also known as a lower extremity thrombosis sheath, is a specially designed brace used to immobilize and support the lower extremities, reducing the risk of venous congestion and thrombosis. Typically made of a soft yet supportive material, it fits snugly against the skin, providing stable pressure and support to maintain blood circulation in the lower extremities.

[0003] Because lower limb support braces have strong wrapping properties and need to provide support, they are generally made of synthetic fibers or plastics. Such materials will restrict the ventilation and perspiration of the skin, causing the legs to sweat easily. In addition, when wearing a lower limb thrombosis support, the support may rub against the skin due to direct contact with the skin, generating frictional heat during the friction process, causing the lower limb support to be locally moist, which is prone to breeding bacteria and fungi. Sweat provides a warm and moist environment for bacterial growth. If the support is not effectively cleaned for a long time, bacteria may breed on the support, increasing the risk of skin infection for the patient, which is not conducive to the patient's use of the lower limb support for rehabilitation.

[0004] In addition, patients are wrapped and restrained in lower limb assistive braces for a long time. Since they are in a static state and muscle activity is restricted, blood flow may be affected, which can easily lead to blood retention, ankle swelling or joint stiffness. Existing lower limb assistive braces cannot help patients exercise, and may easily cause patients to feel discomfort and stiffness due to not wearing them correctly and not exercising correctly.

[0005] In view of this, the present invention provides an auxiliary support device for patients with lower limb thrombosis. Summary of the Invention

Because the embedded shaft 910 and the sliding post 99 are restrained by the sliding frame 98, when the chute frame 97 moves laterally to squeeze the embedded shaft 910, the embedded shaft 910 and the sliding post 99 can only move up and down.

[0048] The following is the entire working process and working principle of the above embodiment:

[0049] Initial state: The drawstring 820 is in a taut state, so it pulls the pressure plate 822 fixed at its lower end to be located below the lower limb cover 1 and does not fit the lower limb cover 1. For details, please refer to Figure 9 The inflatable bandage bag 10 is in a deflated state, so it is convenient for the patient to wear the lower limb cover 1, and when used for the first time, the isolation cotton roll 86 needs to be plugged into the outer wall of the plug column 85, and one end of it needs to pass through the through groove on the outer surface of the lower limb cover 1 and then pass its upper and lower ends through the gap of the U-shaped limiting sleeve 12, so that the U-shaped limiting sleeve 12 limits the upper and lower ends of the isolation cotton roll 86 respectively, and then continue to pull one end of the isolation cotton roll 86 out of the through groove on the outer wall of the lower limb cover 1 again and stick it to the outer wall of the reeling shaft 82. For details, please refer to Figure 3 , initially, the worm 813 is not engaged with the worm wheel 83;

[0050] When working, the patient first puts his foot into the lower limb sleeve 1 from above. At this time, the patient's leg will stick to the rotating wheel 817 and press the magnetic lever 89 to rotate counterclockwise. Figure 5As the patient's leg continues to enter the lower limb sleeve 1, the skin of his leg will rub the rotating wheel 817 to drive the auxiliary shaft 816 to rotate, and will also press the magnetic lever 89 to rotate around the driving support shaft 88, and drive the torsion spring 810 to contract. The rotated magnetic lever 89 will change from horizontal to vertical and be embedded in the built-in groove 87, so that the magnetic lever 89 will no longer attract the magnetic disk 815. Moreover, since the auxiliary shaft 816 and the sleeve shaft 812 are connected by the belt 818, the sleeve shaft 812 and the worm 813 will be driven to rotate synchronously. Since the connecting rod 814 is rotatably connected to the worm 813 through the ring and slides on the upper part of the lower limb sleeve 1, it will not drive the connecting rod 814 to rotate. Since the worm 813 is not engaged with the worm wheel 83 at this time, it will not drive it to rotate. As the patient continues to extend his leg and foot, his foot will resist the pressing plate 822, and the pressing plate 822 pulls the movable rod 821 to The lower limb sleeve 1 slides downward, causing the pressure plate 822 to drive the drawstring 820 fixed thereto to move downward and pull the worm 813 to slide in the sleeve shaft 812, causing the worm 813 to slide in the direction away from the sleeve shaft 812 and approach the worm gear 83, and finally mesh with the worm gear 83. The downward-moving pressure plate 822 will be embedded in the connecting groove 823. At this time, the patient's foot steps on the foot sleeve 5, and then the micro air pump 6 is turned on by the external controller to inflate the inflatable bandage bag 10 through the inflation tube 7 and the connecting tube 11, so that the inflated inflatable bandage bag 10 squeezes and supports the patient's leg, and the step of wearing the lower limb sleeve 1 is completed. At this time, the isolation cotton roll 86 is wrapped around the patient's leg, which can prevent the patient's lower limb from directly contacting the lower limb sleeve 1, prevent bacteria and other pathogens on the patient's skin from breeding on the lower limb sleeve support device, and also improve the comfort of the patient wearing the support sleeve 1.

[0051] Furthermore, when the patient has finished wearing the lower limb sleeve 1 and removes it, the patient lifts his leg upward, which will cause the friction wheel 817 to drive the auxiliary shaft 816 to rotate again, so that the auxiliary shaft 816 will drive the sleeve shaft 812 and the worm 813 to rotate again through the belt 818. Since the worm 813 has been engaged with the worm wheel 83 in the above-mentioned wearing step, it will engage the worm wheel 83 to drive the reel-up shaft 82 to rotate, so that the reel-up shaft 82 drives the other end of the isolation cotton roll 86 to be wound, so that the isolation cotton roll 86 used by the patient can be replaced under the action of the rotation and reeling of the reel-up shaft 82, that is, the step of manually replacing the isolation cotton is omitted, and it can also ensure that the isolation cotton roll 86 after use will not remain in the lower limb sleeve 1 for a long time, avoiding the isolation cotton roll 86 absorbing sweat during wearing and contacting with the lower limb sleeve 1 for a long time and corroding the lower limb sleeve 1, ensuring that the lower limb sleeve 1 is still kept in a better clean state when the patient uses it next time, avoiding the situation where unsanitary lower limb sleeve 1 is infected by bacteria after the patient wears it, and extending the service life of the lower limb sleeve 1 supporter.

[0052] In addition, after the patient's leg is completely removed, the vertical magnetic lever 89 is no longer squeezed. At this time, the torsion spring 810 resets and rebounds, driving the magnetic lever 89 to rotate back to a horizontal state, so that the magnetic lever 89 is once again in the same horizontal plane with the magnetic disk 815, and the magnetic disk 815 can be adsorbed again to drive the worm 813 to slide in the sleeve shaft 812 and return to its initial state, so that the worm 813 is disengaged from the worm wheel 83, avoiding the friction of the rotating wheel 817 when the patient uses it again, causing the meshing worm wheel 83 and the winding shaft 82 to reverse, thereby loosening the outer wall of the winding shaft 82 to isolate the cotton roll 86.

[0053] Furthermore, during the wearing process of the patient, the controller can be used to adjust the inflation degree of the inflatable bag 10 to control the tightness of the support and restraint, and the inflatable bag 10 can be continuously inflated and deflated, so as to achieve the effect of squeezing and massaging through the inflatable bag 10, thereby improving the diversity of the functions of the lower limb support device 1. When the inflatable bag 10 is continuously inflated, it will squeeze the arc plate 93 that fits its outer wall, so that the arc plate 93 squeezes the U-shaped slide bar 92 in the direction away from the inflatable bag 10 and pulls the auxiliary spring 94 on its outer wall to stretch, and the moving U-shaped slide bar 92 will Pull the piston plate 96 at the other end to move in the piston cylinder 95, so that air enters the piston cylinder 95 from the one-way air inlet valve tube 912. When the inflatable bandage bag 10 begins to deflate, the U-shaped slide bar 92 will be rebounded by the auxiliary spring 94 and pulled to its original position. At this time, the air drawn into the piston cylinder 95 will enter the blowing tube 911 through the ventilation tube and be discharged into the lower limb sleeve 1. The legs of the patient who is using the lower limb sleeve 1 can be blown to dissipate heat, which can bring coolness to the patient, ensure air circulation inside the lower limb sleeve 1, reduce the patient's sweating, and further improve the comfort of using the supporter.

[0054] The footrest 910 is a footrest that is fixed to the support frame 98 and is pressed against the support frame 98. The footrest 910 is a footrest that is fixed to the support frame 98 and is pressed against the support frame 98.

[0055] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
