Description

Technical Field

[0001] This invention relates to medical assistive devices, specifically rehabilitation and nursing equipment. Background Technology

[0002] The hip joint, as a core joint of the human body, plays a crucial role in human activity, and its rehabilitation is directly related to a person's normal life. Traditionally, rehabilitation after severe injuries such as hip fractures and cracks relies primarily on caregivers manually assisting patients with movement. However, this method requires significant nursing resources and places a heavy workload on caregivers. Among hip rehabilitation exercises, the most common movement is hip flexion, or leg raising. Especially in the early stages of rehabilitation, when patients primarily rest in a supine position, manual assistance is quite difficult. Therefore, simplifying rehabilitation procedures and reducing the workload of caregivers is an urgent need. Summary of the Invention

[0003] The purpose of this invention is to provide a rehabilitation training device for hip fractures that can improve rehabilitation efficiency.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is: a rehabilitation training device for hip fractures, comprising a pressure plate and motion drive mechanisms disposed on both sides of the lower part of the pressure plate; the motion drive mechanisms are connected to the pressure plate via mounting seats;

[0005] The motion drive mechanism includes a horizontally arranged joint outer cylinder, a reduction gearbox is installed inside the joint outer cylinder, a drive motor is installed at one end of the joint outer cylinder, and a vertical swing arm is installed at the other end; the input end of the reduction gearbox is connected to the drive motor, and the output end is connected to the upper end of the swing arm; the lower end of the swing arm is provided with a support for supporting the patient's leg.

[0006] The motion drive mechanism also includes a position adjustment component, and the joint outer cylinder slides vertically between itself and the mounting base through the position adjustment component.

[0007] Preferably, the position adjustment assembly includes a fixed base, which is L-shaped. One side of the vertical section of the fixed base is connected to a mounting base, and the other side is provided with a side groove extending vertically. A sliding hole extending vertically is provided on the transverse section of the fixed base. An adjusting screw extending along the length of the side groove is provided in the side groove. The adjusting screw is connected to an adjusting motor, and a slider is sleeved on the adjusting screw. The slider has a sliding fit with the side groove and a threaded fit with the adjusting screw.

[0008] The position adjustment assembly also includes a sliding rod passing through a sliding hole, the upper end of which is connected to the slider and the lower end of which is connected to the outer cylinder of the joint.

[0009] Preferably, a vertical limiting plate is provided at the end of the horizontal section of the fixed seat away from the vertical section. The limiting plate has a vertical guide opening, and the outer cylinder of the joint is locked in the guide opening and forms a sliding fit with the limiting plate.

[0010] Preferably, the outer sleeve of the joint outer cylinder located inside the guide opening is provided with a rotating sleeve, and the rotating sleeve contacts the limiting plate.

[0011] Preferably, the support is a C-shaped tray.

[0012] Preferably, the swing arm is L-shaped, and the support is a rotating cylinder disposed outside the lateral section of the swing arm.

[0013] Preferably, the mounting base includes a connecting plate fixedly mounted on the horizontal pressure plate, and the mounting base is fixedly connected to the connecting plate by bolts.

[0014] Preferably, the mounting base includes a hinge shaft disposed on the horizontal pressure plate and a connecting lug disposed on one side of the fixed base. The connecting lug is sleeved on the hinge shaft and forms a hinge with the hinge shaft. A locking handwheel for locking the fixed base and the hinge shaft is provided at the connecting lug.

[0015] Preferably, the back of the horizontal pressure plate is provided with several transverse bottom ridges, the center of the horizontal pressure plate is provided with an air vent, and an air vent mesh is provided inside the air vent.

[0016] The beneficial effects of this invention are mainly reflected in its ability to assist patients in rehabilitation training during the recovery period after hip fractures, and to greatly reduce the operational difficulty and intensity for nursing staff. Specifically, in use, the pressure plate is laid on the hospital bed, and the patient lies down on the pressure plate with their back and buttocks pressed against it, and their legs resting on the support. The drive motor outputs power in the forward direction, driving the swing arm upward through the reduction gearbox. The support on the swing arm lifts the patient's legs, creating a forward flexion. The drive motor outputs power in the reverse direction, causing the swing arm to swing downward and the legs to lower, completing one cycle of rehabilitation movement. Repeatedly driving the swing arm effectively achieves rehabilitation training. This invention eliminates the reliance on manual operation by nursing staff and can greatly assist patients in actively rehabilitating their hip joints. Furthermore, the joint outer cylinder of this invention, as the core position for joint movement, can be adjusted vertically, allowing the swing center to be adjusted according to actual conditions, thus adapting to individual differences and greatly improving comfort.

[0019] Figure 3 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0020] Combination Figures 1-3 As shown, a rehabilitation training device for hip fractures includes a supine pressure plate 1 and motion drive mechanisms disposed on both sides of the lower part of the supine pressure plate 1. The supine pressure plate 1 is used for the patient to lie down and is pressed under the body, serving as the connection base for other components. The motion drive mechanisms are used to perform rehabilitation movements, driving the patient's leg movements to achieve rehabilitation training of the hip joint.

[0021] Generally, the pressure plate 1 can be a thin sheet of ABS plastic, PVC plastic, etc., characterized by its lightweight and high strength. The pressure plate 1 can usually be laid directly on the hospital bed. To ensure sufficient breathability, it has a certain elevation design to form a breathable structure. For example, the back of the pressure plate 1 can have several horizontal bottom ridges. The height of the bottom ridges does not need to be too high, usually around 0.5-1 cm, which improves slip resistance and elevates the pressure plate 1. Furthermore, a ventilation opening can be provided in the center of the pressure plate 1, and a breathable mesh 22 can be installed inside the ventilation opening to improve the breathability of the pressure plate 1 when lying down, thus enhancing comfort.

[0022] The motion drive mechanism of this invention is connected to the horizontal pressure plate 1 via a mounting base 2. The mounting base 2 comes in various forms, primarily divided into fixed and lateral angle adjustable types. The fixed type can be, for example... Figure 2 As shown, the mounting base 2 includes a connecting plate 18 fixedly mounted on the horizontal pressure plate 1, and the fixing base 8 is fixedly connected to the connecting plate 18 by bolts 19. The adjustable lateral angle mainly serves to adjust the lateral opening and closing angle of the motion drive mechanism, accommodating forward flexion training with different leg opening angles. For example... Figure 3 As shown, the mounting base 2 may include a hinge shaft 20 disposed on the horizontal pressure plate 1, and a connecting ear 21 disposed on one side of the base plate (fixed base 8) of the action drive mechanism. The connecting ear 21 is sleeved on the hinge shaft 20 and forms a hinge with the hinge shaft 20. A locking handwheel for locking the base plate (fixed base 8) and the hinge shaft 20 is provided at the connecting ear 21.

[0023] like Figure 1 and 2As shown, the motion drive mechanism includes a laterally arranged joint outer cylinder 3. A reduction gearbox 4 is installed inside the joint outer cylinder 3, which reduces the high-speed rotation of the motor to low-speed, high-torque rotation. A drive motor 5 is installed at one end of the joint outer cylinder 3, and a vertical swing arm 6 is installed at the other end. The input end of the reduction gearbox 4 is connected to the drive motor 5, and the output end is connected to the upper end of the swing arm 6. The movement of the drive motor 5 drives the swing arm 6 to swing. A support member 7 for supporting the patient's leg is installed at the lower end of the swing arm 6. The support member 7 is used to place the patient's leg and can take many forms. For example, the support member 7 can be a C-shaped tray on which the patient's leg rests directly. Alternatively, the swing arm 6 can be L-shaped, and the support member 7 can be a rotating cylinder located outside the lateral section of the swing arm 6, providing support for the leg.

[0024] In use, this invention involves placing the pressure plate 1 on the hospital bed. The patient lies down on the pressure plate 1, with their back and buttocks pressing against it, and their legs resting on the support 7. The drive motor 5 outputs power in the forward direction, driving the swing arm 6 upward through the reduction gearbox 4. The support 7 on the swing arm 6 then lifts the patient's legs, creating a forward flexion. Conversely, the drive motor 5 outputs power in the reverse direction, causing the swing arm 6 to swing downward, lowering the legs and completing one cycle of rehabilitation movement. Repeatedly driving the swing arm 6 effectively achieves rehabilitation training. This invention eliminates the reliance on manual operation by nursing staff and provides excellent assistance to patients in actively rehabilitating their hip joints.

[0025] Of course, due to individual differences among patients and variations in lying posture, the position of the patient's hip joint relative to the supine pressure plate 1 will differ to some extent. Therefore, to adapt to various needs, the motion drive mechanism of this invention should have a certain degree of vertical adjustment capability, thereby improving comfort and rehabilitation effectiveness. Thus, the motion drive mechanism of this invention also includes a position adjustment component, through which the joint outer cylinder 3 forms a vertical sliding relationship with the mounting base 2. In other words, this invention, through the position adjustment component, can adjust the vertical position of the joint outer cylinder 3 in real time to meet specific needs.

[0026] like Figure 2As shown in the figure, the present invention discloses a specific form of a position adjustment component. The position adjustment component includes a fixed base 8, which is L-shaped. One side of the vertical section of the fixed base 8 is connected to the mounting base 2, and the other side is provided with a side groove 9 extending vertically. A sliding hole 10 extending vertically is provided on the horizontal section of the fixed base 8. An adjusting screw 11 extending along the length direction of the side groove 9 is provided in the side groove 9. The adjusting screw 11 is connected to an adjusting motor 12, and a slider 13 is sleeved on the adjusting screw 11. The slider 13 has a sliding fit with the side groove 9 and a threaded fit with the adjusting screw 11. The position adjustment component also includes a sliding rod 14 passing through the sliding hole 10. The upper end of the sliding rod 14 is connected to the slider 13, and the lower end is connected to the joint outer cylinder 3.

[0027] When position adjustment is required, the adjusting motor 12 drives the adjusting screw 11 to rotate, and the slider 13 sleeved on the adjusting screw 11 moves in the up and down direction, that is, along the side groove 9, which in turn drives the sliding rod 14 to move up and down along the sliding hole 10, and finally drives the joint outer cylinder 3 to move. Since the swing center of the swing arm 6 is located inside the joint outer cylinder 3, the swing center of the swing arm 6 is actually changed to adapt to the actual position of the patient's hip joint.

[0028] Of course, to further improve the overall stability of the joint outer cylinder 3, a better approach of the present invention is to provide a vertical limiting plate 15 at the end of the horizontal section of the fixed base 8 away from the vertical section. The limiting plate 15 has a vertical guide opening 16, and the joint outer cylinder 3 is fitted into the guide opening 16, forming a sliding fit with the limiting plate 15. Simultaneously, a rotating sleeve 17 can be fitted over the section of the joint outer cylinder 3 located within the guide opening 16, and the rotating sleeve 17 contacts the limiting plate 15 to reduce friction. Guided by the guide opening 16, the joint outer cylinder 3 can stably move up and down within the guide opening 16.
