Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a leg support for lower limb elevation, dressing changes and exercise. Background Art

[0002] Chronic venous insufficiency, such as primary varicose veins of the great saphenous vein, is a common and frequently occurring disease in the vascular system. In addition to regular medication, surgical treatment and other measures, limb elevation and pressure therapy are also important parts of comprehensive treatment. Raising the affected limb is the simplest, fastest and most effective treatment method. It can quickly reduce swelling, reduce swelling, promote venous return, slow down venous development, and is an economical and safe method that is beneficial to prognosis. In addition, for some patients with swelling in the lower limbs, such as those with swelling in the limbs due to lower limb fractures and those with swelling in the limbs after fracture surgery, the lower limbs need to be elevated and kept elevated for a long time to help reduce swelling in the limbs.

[0003] At present, the commonly used method of raising the affected limb is to use a pillow or bedding to pad under the affected limb, which will cause the following problems: 1. Because pillows or bedding are easily deformed, it is difficult to adjust the affected limb to the appropriate height and maintain that height, which affects the recovery speed.

[0004] Second, since the affected limb is simply placed on a pillow or bedding, the position is not easy to fix. Since the pillow or bedding is relatively soft, the affected limb can easily shift and cause secondary injury.

[0005] 3. Ankle pump exercise can accelerate blood flow in the lower limb veins, relieve blood stasis, and reduce the occurrence of deep vein thrombosis in the lower limbs. The above technology cannot meet the needs of patients for ankle pump exercise.

[0006] 4. During the dressing change process, the affected foot can only be placed on the bed. The affected leg is in a low position and the operation distance is far. The doctor needs to bend over to change the dressing, which is inconvenient to apply force.

[0007] Therefore, how to design a leg brace for lower limb elevation and dressing changes that can meet the patient's needs for ankle pump exercises has become an urgent problem to be solved in the field of medical device technology. Summary of the invention

[0008] The purpose of the present invention is to provide a leg support for lower limb elevation, dressing changes and exercise, which is used for lower limb elevation, dressing changes, and can meet the patient's needs for ankle pump exercises, and is also suitable for affected legs of different body shapes.

[0009] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: A leg support for lower limb elevation, dressing change and exercise, comprising a leg-lifting seat and a foot-resting seat, which are detachably connected. A leg-resting slot is provided on the leg-lifting seat, an A airbag is provided on the bottom surface of the leg-resting slot, and B airbags are provided on both side walls of the leg-resting slot, respectively. The two sides of the A airbag are respectively fixed to the sides of the two B airbags, and a clamping opening is formed in the middle of the two B airbags, and the affected leg is clamped in the clamping opening. The inner cavity of the A airbag is not connected to the inner cavities of the two B airbags. The leg-lifting seat is provided with an A air pump and a B air pump. The A airbag is inflated and deflated by the A air pump, and the two B airbags are inflated and deflated by the B air pump: when the B air pump is inflated, the two B airbags expand in shape and the clamping opening diameter decreases; when the B air pump is deflated, the two B airbags shrink in shape and the clamping opening diameter increases. The footrest is provided with a pedal for ankle pump exercise, the pedal is placed upright and can be flipped vertically, a rotating shaft is provided at the flip connection between the pedal and the footrest, the rotating shaft is provided with a torsion spring, the side of the pedal close to the leg lifting seat is a vertical surface, and the patient's foot is against the vertical surface of the pedal.

[0010] Compared with the prior art, the leg support for lower limb elevation, dressing change and exercise using the above technical solution has the following beneficial effects: 1. The leg support for lower limb elevation, dressing changes and exercise of the present invention can raise the patient's lower limbs through the leg raising seat, so that the height position of the lower limbs can be kept unchanged; because the affected leg is limited in the leg placement groove and clamped by two B airbags, the affected leg is not easily displaced, and there is no need to move the affected leg during dressing changes, thereby avoiding secondary injury.

[0011] 2. Control the inflation volume of the two B airbags and adjust the size of the clamp mouth according to needs, which is suitable for affected legs of different sizes.

[0012] 3. After installing the footrest, the patient presses the pedal with the sole of the foot, causing the pedal to flip downward and the torsion spring to be twisted, performing toe flexion, and then releases the pedal, allowing the torsion spring to reset the pedal and flip it back to its original position, performing dorsiflexion of the foot, thereby assisting the patient to actively perform ankle pump exercises. Ankle pump exercises can accelerate blood flow in the lower limb veins, relieve blood stasis, reduce the occurrence of deep vein thrombosis in the lower limbs, and facilitate recovery.

[0013] Fourth, in the preferred embodiment, after the affected leg is raised by the lifting mechanism I, the position of the affected leg is moved upward, the operating distance is shorter, and the doctor does not need to bend over to change the dressing, which is convenient for operation.

[0014] Preferably, the rotating shaft is driven by a variable frequency motor to rotate, and foot straps and foot buckles are respectively provided on both sides of the vertical surface of the pedal, and the foot straps pass through the foot buckles and are fixed by Velcro. The foot straps fix the patient's foot to the vertical surface of the pedal to prevent the patient's foot from detaching from the pedal. The variable frequency motor drives the rotating shaft to rotate forward, so that the pedal flips downward to perform toe flexion, and the variable frequency motor drives the rotating shaft to rotate reversely, so that the pedal flips back to its original position to perform dorsiflexion, thereby assisting the patient to passively perform ankle pump exercises.

[0015] Preferably, a groove is provided on the footrest, the pedal is perpendicular to the footrest, and there is a gap between the lower end of the pedal and the inner bottom surface of the groove. When the patient's foot is against the vertical surface of the pedal, the patient's heel is suspended in the air and the foot is in a neutral position, thereby avoiding pressure sores on the patient's heel and facilitating the recovery of the affected leg.

[0016] Preferably, a leg strap and a leg buckle are respectively provided on both sides of the leg lifting seat, and the leg strap passes through the leg buckle and is fixed by Velcro. The leg strap is used to increase the fixation of the affected leg to prevent the affected leg from accidentally leaving the leg placement groove.

[0017] Preferably, a base I is provided below the leg-lifting seat, and a lifting mechanism I is provided on the base I. The lifting mechanism I is driven by a hydraulic pump so that the distance between the base I and the leg-lifting seat increases or decreases. A base II is provided below the footrest seat, and a lifting mechanism II is provided on the base II. The lifting mechanism II is driven by a hydraulic pump so that the distance between the base II and the footrest seat increases or decreases. Both the lifting mechanism I and the lifting mechanism II can refer to the scissor-type lifting device of the existing patent CN209010057U. The lifting mechanism I is used to adjust the height position of the leg-lifting seat, and the lifting mechanism II is used to adjust the height position of the footrest seat, so that the patient's lower limbs can be raised to different heights to meet the needs of different patients.

[0018] Preferably, a plate receiving groove is provided under base I, and a plate outlet is provided on the surface of base I close to base II, a vertically movable push button is provided on the upper side of the plate outlet, and an insert block is provided under the push button. A plate placing groove is provided under base II, and a plate fixing groove is provided on the surface of base II close to base I, and a clamping block is provided on the upper wall of the clamping groove. A horizontally movable docking plate is provided in the plate receiving groove, and the docking plate is retracted in the plate outlet. A plurality of fixed openings are provided on the docking plate, and the plurality of fixed openings are arranged along the moving direction of the docking plate. The insert block and the clamping block are both compatible with the fixed openings, and the insert block can be buckled into the fixed opening. The protruding end of the docking plate can be placed in the plate placing groove, and the clamping block can be buckled into the fixed opening. When the footrest is not in use, the docking plate is pushed into the plate outlet and stored in the plate receiving groove to reduce the occupied space. When using the footrest, pull the docking plate out of the plate outlet, adjust the extension length of the docking plate and buckle the plug into the fixed port, then place the extended end of the docking plate in the plate slot and buckle the block into another fixed port. After assembly, the footrest and the leg lift are relatively fixed to prevent accidental displacement between the footrest and the leg lift. The assembly operation is simple, and the distance between the footrest and the leg lift can be adjusted according to needs, so that the leg lift can be placed in different parts of the affected leg, ensuring that the leg lift is away from the dressing change site, and is suitable for affected legs in different dressing change sites.

[0019] Preferably, there are two hook surface stickers on the leg-lifting seat, and the two hook surface stickers are respectively arranged on both sides of the notch of the leg placement groove. It also includes a cushion towel, which can refer to the existing disposable medical waterproof pad (manufactured by Yangzhou Beijian Medical Devices Co., Ltd.). The cushion towel is laid on the surfaces of the A airbag and the two B airbags inside the clamping opening. There is a loop surface sticker under the cushion towel, and the loop surface sticker is respectively fixedly adhered to the two hook surface stickers through Velcro. The affected leg is prone to sweating at the joints with the A airbag and the two B airbags. By replacing the cushion towel, cross-infection can be prevented.

[0020] Preferably, there is a fixed clamp on the side of the I base. The fixed clamp is in a "C" shape and has a clamping groove. The side rod of the existing bed board is clamped in the clamping groove. If the affected leg is longer, the fixed position of the leg bracket is closer to the end board of the bed; if the affected leg is shorter, the fixed position of the leg bracket is farther from the end board of the bed. By fixing the leg bracket at different positions on the side rod of the bed board through the fixed clamp, it is applicable to patients of different heights.

[0021] Preferably, there is an anti-slip part on the upper wall of the clamping groove of the fixed clamp, and the anti-slip part is made of elastic silicone material. The anti-slip part is used to increase the friction between the clamping groove and the side rod of the bed board, and the side rod of the bed board is not easily separated from the clamping groove.

[0022] Preferably, there is a retractable movable block on the lower wall of the clamping groove of the fixed clamp. A spring is provided at the retracted end of the movable block, and the telescopic direction of the spring is the same as that of the movable block. The extended end of the movable block presses on the lower surface of the side rod of the bed board: when the movable block retracts, the spring is compressed; when the movable block extends, the spring returns to its original position. By pressing the side rod of the bed board with the movable block, the fixation between the side rod of the bed board and the fixed clamp is further enhanced, preventing the side rod of the bed board from separating from the clamping groove.

DETAILED DESCRIPTION

[0043] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0044] Example 1 like Figures 1 to 9 The leg support for lower limb elevation, dressing change and exercise shown in the figure comprises a leg-lifting seat 1 and a foot-resting seat 2, and the leg-lifting seat 1 and the foot-resting seat 2 are detachably connected. A leg-resting slot 5 is provided on the leg-lifting seat 1, and an A airbag 53 is provided on the inner bottom surface of the leg-resting slot 5. B airbags 54 are provided on the two side walls of the leg-resting slot 5, respectively. The two sides of the A airbag 53 are respectively fixed to the sides of the two B airbags 54, and a clamping opening 50 is formed in the middle of the two B airbags 54, and the affected leg is clamped in the clamping opening 50. The inner cavity of the A airbag 53 is not connected with the inner cavities of the two B airbags 54. The leg-lifting seat 1 is provided with an A air pump and a B air pump. The A airbag 53 is inflated and deflated by the A air pump, and the two B airbags 54 are inflated and deflated by the B air pump: when the B air pump is inflated, the two B airbags 54 expand in shape, the caliber of the clamping opening 50 is reduced, and the affected leg is clamped; when the B air pump is deflated, the two B airbags 54 shrink in shape, the caliber of the clamping opening 50 is increased, and the affected leg is released. By raising the patient's lower limbs on the leg-lifting seat 1, the height position of the lower limbs can be kept unchanged; since the affected leg is limited in the leg-resting slot 5 and clamped by two B airbags 54, the affected leg is not easily displaced, and there is no need to move the affected leg when changing the dressing, thereby avoiding secondary injury.

[0045] Among them, the inflation amount of the two B airbags 54 can be controlled, and the diameter of the clamp 50 can be adjusted according to needs, which is suitable for affected legs of different sizes.

[0046] Reference Figures 7 to 9The footrest 2 is provided with a pedal 6 for ankle pump exercise. The pedal 6 is placed upright and can be flipped vertically. The pedal is provided with a rotating shaft 60 at the flip connection with the footrest 2. The rotating shaft 60 is provided with a torsion spring. The side of the pedal 6 close to the leg lifting seat 1 is a vertical surface, and the patient's foot is against the vertical surface of the pedal 6. The sole of the foot presses the pedal 6 hard, so that the pedal 6 flips downward and the torsion spring is twisted, and the toe is flexed. Then the pedal 6 is released, and the torsion spring is reset to make the pedal 6 turn back to its original position, and the foot is dorsiflexed, thereby assisting the patient to actively perform ankle pump exercise. After installing the footrest 2, the patient's needs for ankle pump exercise can be met. Ankle pump exercise can accelerate the blood flow in the lower limb veins, relieve blood stasis, reduce the occurrence of deep vein thrombosis in the lower limbs, and is conducive to rehabilitation.

[0047] Among them, a groove 26 is provided on the footrest 2, and the pedal 6 is perpendicular to the footrest 2. There is a gap between the lower end of the pedal 6 and the inner bottom surface of the groove 26. When the patient's foot is against the vertical surface of the pedal 6, the patient's heel is suspended in the air and the sole of the foot is in a neutral position, which avoids pressure sores on the patient's heel and is beneficial to the recovery of the affected leg.
