Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an adjustable resistance training device for exercising lower limbs on a bed. Background Art

[0002] Surveys show that approximately 90% of stroke patients experience varying degrees of motor dysfunction, and approximately 60% of these patients experience mobility impairment, difficulty moving the paretic side, limited function, and inability to care for themselves. This ultimately leads to disuse syndrome, a major obstacle to rehabilitation. This not only directly leads to loss of self-care and work abilities, severely impacting patients' quality of life, but also places a heavy emotional and financial burden on their families and society. Active and passive lower limb range of motion exercises are the most common early rehabilitation treatments for lower limb motor dysfunction. Numerous studies have shown that early, continuous active and passive lower limb range of motion exercises can increase sensory stimulation to the affected lower limb, prevent lower limb joint contractures, promote blood circulation in the lower limb, prevent deep vein thrombosis (DVT), and promote lower limb muscle strength recovery, enabling patients to ambulate sooner, improving rehabilitation efficiency and ultimately reintegrating into society.

[0003] For example, the utility model disclosed in the authorization announcement number CN218420855U discloses a lower limb exercise device, which includes a bracket, an L-shaped bracket, a force pedal provided on the inner side of the vertical section, a resistance device provided inside the force pedal, and a pressure dial provided on the vertical section. The pressure dial is connected to a pressure sensor provided on the resistance device and can display the pressure value. This solution enables patients with lower limb fractures or long-term bedridden patients to independently perform quadriceps isometric contraction training and ankle pump exercises in bed, and displays the strength, making it convenient for patients to adjust the strength at any time and show the results of their exercise. However, the above technical solution can only detect the strength of the footsteps, and cannot adjust the resistance of the patient's lower limb load, nor can it perform progressive functional exercise on the patient's lower limbs. At the same time, it cannot perform multi-level positioning and fixation of the patient's feet, and the stability of use is not high. For this reason, we propose an adjustable resistance training device for exercising the lower limbs in bed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4 The utility model provides a technical solution: an adjustable resistance training device for exercising the lower limbs on a bed, comprising a weight plate 5, a support base 4 with an inclined surface provided on the weight plate 5, a guide opening 3 provided on the support base 4, and an adjustable load structure 1 for performing progressive exercises on the patient's lower limbs provided in the guide opening 3;

[0025] The adjustable load structure 1 includes an inclined platform 101, which is arranged in the support seat 4. A plurality of stacked load blocks 105 are arranged on the inclined platform 101. Specifically, the load blocks 105 are marked with corresponding load weights, which are convenient for adjusting the load weight and then accurately adjusting the resistance. Positioning slots 104 are respectively provided on the load blocks 105, and positioning pins 108 can be fixed in the positioning slots 104. The positioning pins 108 are provided at one end of the elastic rope 102, and the other end of the elastic rope 102 is connected to the guide seat 103. The positioning pins 108 pass through the positioning holes 107 corresponding to the positioning slots 104. The positioning holes 107 are provided on the adjustment plate 106, and the adjustment plate 106 is provided on the guide seat 103. The guide seat 103 is movably provided in the guide port 3.

[0026] First, the patient lies flat on the bed, and the patient's feet are fixed by the fixing structure 2. Then, the positioning pin 108 is pulled, and the positioning pin 108 stretches the elastic rope 102, and the positioning pin 108 is inserted into the uppermost positioning hole 107 on the adjustment plate 106, and the positioning pin 108 is inserted into the positioning slot 104 on the uppermost load block 105. Then, the patient performs lower limb extension exercises along the inclination of the support seat 4. The fixing structure 2 drives the guide seat 103 to move in the guide opening 3, and the limiting slider 112 moves in the limiting slide groove 6. When the guide seat 103 moves, the uppermost load block 105 can be moved by the adjusting plate 106 and the positioning pin 108, thereby performing lower limb exercise. By inserting the positioning pin 108 into the positioning slots 104 at different positions, multiple groups of load blocks 105 can be used in combination, and the load resistance can be adjusted, thereby achieving progressive exercise of the lower limbs and facilitating rapid recovery of the patient's lower limb function.

When the guide seat 103 moves, it drives the limit slider 112 to move in the limit slide groove 6, which can guide and limit the moving position of the guide seat 103.

[0028] Furthermore, a sliding sleeve 111 is respectively provided on both sides of the load block 105, and the sliding sleeve 111 is movably provided on the guide column 110, the guide column 110 is provided in the mounting frame 109, and the mounting frame 109 is provided on the inclined platform 101. When the load block 105 moves, the sliding sleeve 111 is driven to move along the guide column 110, thereby improving the guidance of the load block 105 during movement.

[0029] As a specific embodiment of this application, please refer to Figure 1 and Figure 5The guide seat 103 is also provided with a fixing structure 2 for positioning the patient's foot. The fixing structure 2 includes a cross frame 21, which is arranged on the guide seat 103. Foot fixing components are respectively arranged at both ends of the cross frame 21. The foot fixing components include a foot baffle 22, which is arranged on the cross frame 21. Fixing straps 23 for fixing the instep are evenly arranged on the foot baffle 22, which can fix the patient's instep. A heel positioning seat 25 is also provided on one side of the foot baffle 22, which can support the patient's heel. An arc-shaped positioning groove 24 is provided on the heel positioning seat 25, which can position the patient's heel.

[0030] The patient places the heel in the arc-shaped positioning groove 24 on the heel positioning seat 25, fits the sole of the foot against the footstep baffle, and then fixes the instep with the fixing strap 23, so that the patient's foot can be quickly fixed.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood 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 present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
