Description

Technical Field

[0001] The present invention relates to the technical field of multi-functional postoperative rehabilitation assisted walking for pediatric surgery, and specifically to a multi-functional postoperative rehabilitation assisted walking device for pediatric surgery. Background Art

[0002] After pediatric surgery, the patient's body is in the recovery stage, and the recovery of walking ability is crucial for the rehabilitation process. However, there are significant differences between the body structure and physiological characteristics of children and adults. Their bones and joints are still developing, and special care and assistance are required during the postoperative rehabilitation process. Currently, most of the common rehabilitation assisted walking devices on the market are designed for adults and are difficult to meet the special needs of pediatric postoperative rehabilitation. In addition, with the development of rehabilitation medicine, the importance attached to postoperative rehabilitation is increasing, and parents and medical institutions have put forward higher requirements for the safety, effectiveness, comfort and humanized design of rehabilitation assisted devices. Therefore, developing a multi-functional assisted walking device specifically designed for pediatric postoperative rehabilitation has important practical significance and market demand.

[0003] The existing Chinese patent with the publication number CN112870030B includes a base, a lifting support mechanism and a moving speed limiting mechanism. The base is a ring-shaped rectangular structure as a whole. The upper end of the base is fixedly installed with a lifting support mechanism, and several moving speed limiting mechanisms are uniformly arranged along the edge of the lower end surface of the base. Among them: the lifting support mechanism includes a supporting plate, a fixed block, a lifting bar, a locking chain, a moving block, a sliding rod, an adjusting groove, an adjusting spring, a collision prevention spring and a collision prevention plate.

[0004] When the above structure is in use, the lifting bar is used to support the supporting plate to ensure that the supporting plate can withstand a certain intensity of force. At the same time, when targeting children of different heights, the lifting of the supporting plate is restricted by the locking chain, so that the height can be adjusted manually to adapt to children of different heights. However, in the actual use process, since the surgical site of the child is on the leg, resulting in the lack of leg strength, when the child walks by himself, he cannot control the walking speed and strength, and is prone to losing strength during walking and falling, causing secondary injuries. Therefore, it is difficult to assist the child to walk uniformly on the ground.

[0005] Therefore, we propose a multi-functional postoperative rehabilitation assisted walking device for pediatric surgery. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-functional postoperative rehabilitation assisted walking device for pediatric surgery, which has the advantage of assisting children to walk uniformly on the ground and solves the problems in the background art.

[0007] To achieve the above object, the present invention provides the following technical solution: A multifunctional postoperative rehabilitation walking assistance device for pediatric surgery, including a U-shaped base driven by peripheral universal wheels for movement. A rectangular frame is fixedly connected to the U-shaped base, and movable grooves are opened at symmetric positions on both sides of the rectangular frame. The inner walls of the two movable grooves are both movably connected with first support blocks for horizontal reciprocating movement. Lift rods are connected to the two first support blocks for lifting movement, and chutes for supporting the lift rods are opened on the first support blocks. The bottom ends of the two lift rods are both fixedly connected with pedal boards for supporting the feet of children. L-shaped blocks are fixedly connected to symmetric positions on both sides of each pedal board. The opposite ends of the two L-shaped blocks on each side are both fixedly connected with arc-shaped shells for limiting and supporting the legs of children. A walking assistance mechanism for assisting children to walk at a constant speed and a support mechanism for supporting the body of children are provided on the rectangular frame.

[0008] Preferably, the walking assistance mechanism includes an inverted U-shaped frame fixedly connected to the rectangular frame. Second support blocks are rotatably connected to symmetric positions on both sides of the inverted U-shaped frame near the ends through pins. Swing rods for supporting the lift rods are reciprocally connected to the two second support blocks, and chutes for supporting the swing rods are opened on the second support blocks. The end portions of each side of the swing rods are respectively rotatably connected to the end portions of the adjacent lift rods through pins.

[0009] Preferably, cranks for driving the swing rods to swing reciprocally are rotatably connected to symmetric positions on both sides of the inverted U-shaped frame. The end portions of each side of the cranks are respectively rotatably connected to the bottom ends of the adjacent swing rods through pins. A fixed seat is fixedly connected to the inner wall of the inverted U-shaped frame. A motor is fixedly connected to the fixed seat for driving the two cranks to rotate about a fixed axis, and the two ends of the output shaft of the motor are coaxially fixedly connected to the adjacent cranks.

[0010] Preferably, the support mechanism includes a rectangular plate arranged on the top of the U-shaped base, and a support hole for supporting the waist of children is opened on the rectangular plate. Fixed rings are fixedly connected to symmetric positions on both sides of the rectangular plate near the support hole. Annular buckles are sleeved on the inner walls of the two fixed rings. A restraint belt for supporting the buttocks of children is sleeved on the inner walls of the two annular buckles.

[0011] Preferably, rectangular sleeve rods are fixedly connected to symmetric positions on both sides of the U-shaped base. Rectangular insertion rods for adaptively adjusting the height of the rectangular plate are connected to the inner walls of the two rectangular sleeve rods for lifting movement. The end portions of the two rectangular insertion rods are fixedly supported on symmetric positions on both sides of the bottom of the rectangular plate. First springs for guiding the rectangular plate to move back to its original position are fixedly connected to the opposite surfaces of each rectangular insertion rod and the rectangular sleeve rod.

[0012] Preferably, rectangular grooves are formed in both of the pedal steps on both sides. An airbag pad for buffering the pressure of a child's feet is fixedly connected between the inner wall of each rectangular groove and the inner wall of the arc-shaped housing. An inflation mechanism for inflating or exhausting the inside of the airbag pad is provided on the rectangular frame.

[0013] Preferably, the inflation mechanism includes cylindrical housings fixedly connected to the inner walls of the movable grooves on both sides of the rectangular frame near one end of the U-shaped base. The opposite sides of both cylindrical housings away from one end of the first support block are penetrated and fixedly connected with connecting pipes. One end of each connecting pipe away from the cylindrical housing penetrates through the inner walls of the pedal step and the airbag pad and is fixedly connected.

[0014] Preferably, fixed blocks are fixedly connected to the inner walls of both cylindrical housings away from the connecting pipes. The fixed blocks on both sides are penetrated and axially movably connected with moving rods. One end of each moving rod close to the connecting pipe is fixedly connected with a piston plate for inflating or exhausting the inside of the airbag pad, and the piston plate is movably connected with the inner wall of the cylindrical housing. Second springs for guiding the piston plate to move back and forth are fixedly connected to the opposite surfaces of the piston plate and the fixed blocks on both sides. One end of each moving rod away from the piston plate is fixedly connected with a moving block that reciprocates inside the movable groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] First, by using a crank and a swing rod driven by a motor to drive the lifting rod and the pedal step to perform regular lifting and forward and backward alternating movements, the gait rhythm of natural walking is simulated, assisting the child to walk at a uniform speed on the ground, solving the problem that the existing device cannot effectively control the walking speed and strength, ensuring that the child maintains a correct posture during walking, and avoiding the phenomenon of exhaustion and falling caused by insufficient leg strength and unstable walking of the child, significantly improving the safety of walking.

[0017] Second, through the combined design of the rectangular sleeve rod, the rectangular insertion rod, and the first spring, the height of the rectangular plate is adjusted adaptively. During use, the weight of the child can automatically compress or stretch the first spring, thereby adjusting the height of the rectangular plate, ensuring that the device always provides appropriate support force for the child, and being able to adapt to children of different heights and weights. As the child's body moves up and down during walking, the rectangular plate can be lifted and lowered synchronously under the action of the first spring, ensuring that the rectangular plate can always maintain an upward supporting force on the child, effectively preventing secondary injuries caused by falling, and providing a strong guarantee for postoperative rehabilitation.

[0018] III. An airbag pad is provided at the pedal and the leg support part, and an inflation mechanism is equipped. During walking, by adjusting the height of the lifting rod and the inflation amount of the airbag pad, it is ensured that the best auxiliary effect is always provided during use. The airbag pad can dynamically inflate and deflate according to the pressure changes of the child's feet and legs through the coordinated action of the piston plate and the spring, effectively buffering the foot pressure, reducing the fatigue during walking, and can also gently massage and press the child's leg muscles, promoting blood circulation and accelerating the postoperative rehabilitation effect.

[0019] Through the combined use of the above structures, the problem that in the actual use process of the existing device, due to the surgical site of the child being on the leg, resulting in the lack of leg strength, when the child walks by himself, he cannot control the walking speed and strength, easily leads to loss of strength during walking, falls, and causes secondary injuries, so it is difficult to assist the child to walk uniformly on the ground is solved.

[0044] The support mechanism includes a rectangular plate 16 provided at the top of the U-shaped base 1, and a support hole 161 for supporting the waist of a child is provided on the rectangular plate 16. Fixed rings 18 are fixedly connected to symmetric positions on both sides of the rectangular plate 16 near the two sides of the support hole 161. An annular buckle 19 is sleeved on the inner walls of the two fixed rings 18, and a restraint belt 20 for supporting the buttocks of the child is sleeved on the inner walls of the two annular buckles 19.

[0045] Rectangular sleeve rods 14 are fixedly connected to symmetric positions on both sides of the U-shaped base 1. A rectangular insertion rod 15 for adaptively adjusting the height of the rectangular plate 16 is connected to the inner walls of the two rectangular sleeve rods 14 in a lifting and moving manner. The ends of the two rectangular insertion rods 15 are fixedly supported on symmetric positions on both sides of the bottom of the rectangular plate 16. A first spring 17 for guiding the rectangular plate 16 to move back is fixedly connected to the opposite surfaces of each rectangular insertion rod 15 and the rectangular sleeve rod 14.

[0046] During use, through the rectangular sleeve rod 14 and the rectangular insertion rod 15 provided on the U-shaped base 1, the rectangular insertion rod 15 is connected to the inner wall of the rectangular sleeve rod 14 in a lifting and moving manner, and the rectangular plate 16 is fixedly supported on the rectangular insertion rod 15 to ensure the stability of the rectangular plate 16. And the support hole 161 opened on the rectangular plate 16. First, place the child on the inner wall of the support hole 161, so that the support hole 161 can support the feet of the child and prevent the child from falling during walking. Through the fixed rings 18 provided on the rectangular plate 16, the fixed rings 18 can be fixedly supported on the rectangular plate 16.

An airbag pad 21 for buffering the pressure on the child's feet is fixedly connected between the inner wall of each rectangular groove 501 and the inner wall of the arc-shaped housing 7. An inflation mechanism for inflating or exhausting the inside of the airbag pad 21 is provided on the rectangular frame 2.

[0052] During use, through the rectangular groove 501 formed in the pedal board 5, and the airbag pad 21 provided on the inner wall of the rectangular groove 501 and the inner wall of the arc-shaped housing 7, the airbag pad 21 is fixedly supported on the inner walls of the rectangular groove 501 and the arc-shaped housing 7. And the airbag pad 21 is in contact with the child's feet and legs. Then, the airbag pad 21 can slow down the pressure on the feet, further improving the comfort. And the inflation mechanism provided on the rectangular frame 2 enables the inflation mechanism to inflate and exhaust the inside of the airbag pad 21, and the airbag pad 21 expands and contracts, realizing the pressing of the child's foot and leg muscles, promoting blood circulation, and further improving the postoperative rehabilitation effect.

[0053] Embodiment 5:

[0054] On the basis of Embodiment 4, further:

[0055] The inflation mechanism includes cylindrical shells 22 fixedly connected to the inner walls of the two movable grooves 201 on both sides of the rectangular frame 2 close to one end of the U-shaped base 1. The opposite sides of both cylindrical shells 22 away from the first support block 3 are penetrated and fixedly connected with connecting pipes 23. One end of each connecting pipe 23 away from the cylindrical shell 22 penetrates through the inner walls of the pedal board 5 and the airbag pad 21 and is fixedly connected.

[0056] On the inner wall of each cylindrical housing 22 at the end far from the connecting pipe 23, a fixing block 24 is fixedly connected. The two fixing blocks 24 are penetrated and axially movably connected with a moving rod 25. At one end of each moving rod 25 close to the connecting pipe 23, a piston plate 26 for inflating or exhausting the airbag cushion 21 is fixedly connected. The piston plate 26 is movably connected with the inner wall of the cylindrical housing 22. On the opposite surfaces of each piston plate 26 and the fixing block 24, a second spring 27 for guiding the piston plate 26 to move back and forth is fixedly connected. At one end of the two moving rods 25 far from the piston plate 26, a moving block 28 for reciprocating movement in the moving groove 201 is fixedly connected.

[0057] During use, through the cylindrical housing 22 provided on the moving groove 201, the cylindrical housing 22 is fixedly supported on the inner wall of the moving groove 201. And the connecting pipe 23 provided on the cylindrical housing 22 enables the connecting pipe 23 to communicate the inner walls of the cylindrical housing 22 and the airbag cushion 21. And the fixing block 24 provided on the cylindrical housing 22, then the fixing block 24 is fixedly supported on the inner wall of the cylindrical housing 22. Through the moving rod 25 provided on the fixing block 24, and the piston plate 26 provided on the moving rod 25, the moving rod 25 can drive the piston plate 26 to axially reciprocate and move on the inner wall of the cylindrical housing 22. And the second spring 27 provided on the piston plate 26 enables the second spring 27 to support the position of the piston plate 26 under the action of elastic force. And the moving block 28 provided on the moving rod 25, then the moving groove 201 provides movable support for the moving block 28.

[0058] In the initial state, the piston plate 26 is located at the limit position at one end of the fixed block 24 under the elastic force of the second spring 27. Along with the lifting and lowering and reciprocating movement of the pedal 5 driven by the lifting rods 4 on both sides, the first support block 3 can move horizontally and reciprocally synchronously along the inner wall of the movable groove 201 under the action of the lifting rods 4. When the first support block 3 moves towards the end close to the cylindrical housing 22, the first support block 3 contacts the moving block 28 and pushes the piston plate 26 to move towards the end close to the connecting pipe 23 through the moving rod 25, and the second spring 27 is stretched under the action of the piston plate 26. At this time, the internal air pressure at the end of the cylindrical housing 22 close to the connecting pipe 23 is positive pressure, so that the connecting pipe 23 can fill the internal air pressure of the cylindrical housing 22 into the airbag pad 21, causing the airbag pad 21 to expand and press the muscles of the child's feet and legs. When the first support block 3 moves back towards the end away from the cylindrical housing 22, the first support block 3 disengages from the moving block 28, causing the piston plate 26 to move back towards the end away from the connecting pipe 23 under the pulling action of the second spring 27. At this time, the internal air pressure at the end of the cylindrical housing 22 close to the connecting pipe 23 is in a negative pressure state, and then the connecting pipe 23 can extract the gas inside the airbag pad 21 into the cylindrical housing 22, and the airbag pad 21 contracts. Through the cooperation of the above structures, the reciprocating pressing of the muscles of the child's feet and legs is realized, promoting blood circulation in the child's feet and legs and improving the postoperative rehabilitation effect.

[0059] Furthermore, it is realized that the existing device can assist children to walk uniformly on the ground during actual use, which is convenient to use and better than traditional products.

[0060] The standard parts used in this embodiment can be directly purchased from the market, and the non-standard structural components recorded according to the description of the specification and the drawings can also be directly processed without doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.
