Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a rehabilitation device for use after lower limb fractures and joint replacement surgeries. Background Art

[0002] Lower limb fractures are mostly caused by external violence. Whether internal fixation or external fixation surgery is used for treatment, metal material (steel or titanium) plates and screws are usually used to fix the fractured and displaced bone blocks, helping the patient to restore their bony anatomical structure as soon as possible, restore the alignment, restore their early mobility after the fracture surgery, and maintain the original functions of the relevant joints of the lower limbs. Similarly, joint replacement surgery is also a common orthopedic treatment measure in the end stage of severe osteoarthropathy. Briefly stated, it is to remove the cartilage surface that has undergone long-term degeneration and severe damage, and the bone surface part below it, and replace it with an artificial designed prosthesis component. Each step in joint replacement surgery has to consider whether the relevant functions will be affected, whether the implant is suitable, and whether there is sufficient stability after fixation, etc., and it is necessary to ensure that the patient can resume their normal activities after the surgery.

[0003] Therefore, the rehabilitation exercise after the surgery is also very important, which directly affects the occurrence of complications such as thrombosis in the patient, and secondary injuries such as local soft tissue swelling and necrosis. As we know, the flexion and extension functions and muscle strength of the lower limbs are important bases for ensuring independent walking in daily life, and are also clinical reflections of the overall recovery effect after orthopedic surgery. Clinically, the main goal of knee joint rehabilitation training is to maintain the range of motion such as flexion, extension, and rotation of the knee joint after the surgery to meet the needs of daily life. Immobilization can lead to a slowdown in blood flow velocity in the lower limbs, which is also one of the factors causing deep vein thrombosis in the lower limbs.

[0004] However, after the surgery, the muscles and other soft tissues are incised and sutured, and inflammatory reactions occur after local trauma. The soft tissues are usually very painful and cannot independently complete rehabilitation exercises such as joint activities. Medical, technical, and nursing staff are often required to assist in the rehabilitation treatment, and there is a large demand for experienced professional rehabilitation therapists. Due to the severe shortage of rehabilitation therapists, in many grass-roots hospital orthopedics departments, nurses who have received simple training often replace the work of rehabilitation therapists. However, due to professional differences and the lack of standardization in their rehabilitation treatment, non-professional therapists often use excessive force in a simple and rough manner, resulting in increased pain for the patient and the risk of refracture, poor patient compliance, and the postoperative disability reduction rate not reaching the ideal situation. Summary of the Invention

[0005] The purpose of the present invention is to provide a rehabilitation device for use after lower limb fractures and joint replacement surgeries, which solves the problem in the background art that it is inconvenient for patients with lower limb fractures and joint replacement to exercise independently.

[0006] The above technical object of the present invention is achieved by the following technical solution: A rehabilitation device for lower limb fractures and after joint replacement surgery, including a panel, a support frame is provided under the panel, a first groove and a second groove are opened in the middle of the panel, the second groove is communicated with the first groove, a rotating plate is rotatably connected in the first groove, a first chute is jointly opened in the first groove and the second groove, a lead screw is rotatably connected in the first chute, a first slider and a second slider are threadedly connected to the lead screw, both the first slider and the second slider are slidably connected in the first chute, a support rod is rotatably connected to the first slider, and the end of the support rod away from the first slider is rotatably connected to the lower side wall of the rotating plate; a placement groove is opened in the second groove, a flexion and extension airbag is provided in the placement groove, a sealing plate is fixedly connected to the second slider, and the sealing plate is slidably connected in the second groove; a power chamber is opened in the panel, one end of the lead screw penetrates into the power chamber, a first bevel gear is provided on the lead screw in the power chamber, a connecting rod is rotatably connected in the panel, one end of the connecting rod penetrates into the power chamber, a second bevel gear is provided on the connecting rod in the power chamber, the second bevel gear is meshed with the first bevel gear, the other end of the connecting rod is fixedly connected with a turntable located outside the panel, and a handle is provided on the turntable; an inflation mechanism for inflating the flexion and extension airbag is installed on one side of the panel, and a deflation valve for deflating the flexion and extension airbag is installed on the other side of the panel.

[0007] By adopting the above technical solution, when the patient does not need to exercise, the entire panel is an ordinary bed and can be used for the patient to rest; when the patient has the need to exercise, first turn the handle to drive the turntable to rotate, and then drive the lead screw to rotate through the second bevel gear, the connecting rod and the first bevel gear. The lead screw drives the first slider and the second slider to slide in the first groove. When the first slider slides towards the head of the bed, through the support rod rotatably connected to the first slider and the rotating plate, the side of the rotating plate facing the end of the bed can be jacked up, thereby lifting the patient's thigh, making the patient's thigh and calf in a flexion and extension state. At the same time, the second slider also slides towards the head of the bed, and the second slider drives the sealing plate to move towards the head of the bed, so that the sealing plate leaves the second groove and opens the placement groove; then start the inflation mechanism to make the flexion and extension airbag expand, thereby lifting the calf. When the flexion and extension airbag is fully inflated, the patient's thigh and calf are in a straight line. Then the patient can deflate the flexion and extension airbag through the deflation valve, so that the calf bends downward, so as to achieve the effect of independently exercising the hip, knee and ankle joints. It has been proved by clinical experience that the exercise method of raising the lower limb above the heart position can minimize the probability of the patient suffering from lower limb deep vein thrombosis, and the patient can also deflate the flexion and extension airbag regularly and quantitatively according to his own pain level or deflate it to minimize his own pain level.

[0008] The present invention is further configured such that: a foot massage mechanism is provided at the tail of the panel. The foot massage mechanism includes two foot sleeves and a mounting portion fixed to the tail of the panel. Both of the two foot sleeves are sewn from double-layer elastic non-woven fabric. A massage airbag is provided between the two layers of elastic non-woven fabric. The shape of the massage airbag matches the shape of the foot sleeve and fills the space between the two layers of elastic non-woven fabric. A cylinder and a corrugated pipe are installed in the mounting portion. The piston rod of the cylinder is fixed to one side of the corrugated pipe. The side of the corrugated pipe away from the cylinder is fixed in the mounting portion. The corrugated pipe is filled with inert gas. The corrugated pipe is communicated with an air injection pipe. The free end of the air injection pipe passes through the mounting portion and is communicated with the two massage airbags.

[0009] By adopting the above technical solution, the two foot sleeves can be put on the patient's feet, and then the cylinder is started. The piston rod of the cylinder compresses the corrugated pipe, pressing the inert gas in the corrugated pipe into the massage airbag, causing the massage airbag to bulge, exerting a pressing effect on the entire foot of the patient (including the sole and the instep). Then the piston rod of the cylinder pulls the corrugated pipe back to its original position, causing the inert gas in the massage airbag to return to the corrugated pipe, so that the massage airbag no longer presses on the foot. By the cylinder pushing the corrugated pipe to make such a reciprocating motion, the massage airbag continuously presses on the foot, playing a role in massaging the patient's foot. In cooperation with the knee joint flexion and extension movement, it can promote the patient's blood circulation, further reduce the probability of complications such as thrombosis, and at the same time can also accelerate the patient's recovery speed.

[0010] The present invention is further configured such that: the inflation mechanism includes an inflation cylinder. The inflation cylinder is installed on the side wall of the panel through a clamp. A piston plate is slidably connected in the inflation cylinder. A push rod is fixedly connected to the piston plate. The end of the push rod away from the piston plate is fixedly connected to a handle located outside the inflation cylinder. A first one-way valve and a second one-way valve are installed on the side of the inflation cylinder away from the handle. The first one-way valve is communicated with an air inlet pipe. The other end of the air inlet pipe passes into the placement groove and is communicated with the flexion and extension airbag. A deflation valve is connected to an air outlet pipe. The other end of the air outlet pipe passes into the placement groove and is communicated with the flexion and extension airbag.

[0011] By adopting the above technical solution, it enables the patient to inflate and deflate independently, facilitating the patient's self-operation.

[0012] The present invention is further configured such that: two elastic bands are fixedly connected to the rotating plate. One of the elastic bands is provided with a hook surface of a magic tape, and the other elastic band is provided with a loop surface of a magic tape.

[0013] By adopting the above technical solution, the thigh part of the patient can be fixed on the rotating plate, making the patient's flexion and extension movement smoother.

[0014] The present invention is further configured such that a pillow is provided at the head of the panel.

[0015] By adopting the above technical solution, the head of the patient can be made more comfortable.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The rehabilitation device is provided with structures such as a panel, a rotating plate, a sealing plate, and a flexion and extension airbag. When the patient does not need to exercise, the entire panel can be used for the patient to lie flat and rest. When the patient needs to exercise, the handle is directly rotated to lift one side of the rotating plate, thereby lifting the thigh. Then, the flexion and extension airbag is inflated, so that the flexion and extension airbag also lifts the lower leg. Then, the lower leg can be lowered by deflating the flexion and extension airbag, thereby achieving the purpose of rehabilitation treatment. It has been proven by clinical experience that the flexion and extension exercise method of first lifting the thigh and then bending the lower leg can minimize the pain of the patient to the greatest extent, and at the same time can also improve the range of motion of the hip and knee joints; and the patient can deflate or inflate the flexion and extension airbag regularly and quantitatively according to his own pain level, so that the pain level of the patient can be minimized during exercise.

[0018] 2. The rehabilitation device is provided with a foot massage mechanism, and the bellows continuously inflates and deflates the massage airbag, which can continuously massage the sole and instep of the patient's foot. By cooperating with the flexion and extension movement of the knee joint, it can promote the blood circulation of the patient, further reduce the probability of complications such as thrombosis, and at the same time can also accelerate the speed of the patient's recovery.

[0019] 3. This device implements accurate rehabilitation treatment measures that meet the standards for patients with lower limb fractures and after joint replacement, reduces the repetitive work of rehabilitation therapists, and expands the service volume. It provides repeatable and standardized treatment measures for the auxiliary rehabilitation work of non-rehabilitation treatment professionals in medical institutions, which is safe and reliable.

At the left and right ends of the lower side of the panel 1, H-shaped support frames 2 are installed by screws. A pillow 39 is placed on the upper left side of the panel 1. A first groove 3 and a second groove 4 are formed in the middle of the upper side of the panel 1. The second groove 4 is located on the right side of the first groove 3. The first groove 3 is deeper than the second groove 4, and the right side of the first groove 3 communicates with the left side of the second groove 4. A rotating plate 5 is rotatably connected in the first groove 3. A first rotating shaft passes through the left end of the rotating plate 5, and the front and rear ends of the first rotating shaft are rotatably connected to the front and rear side walls in the first groove 3. And when the rotating plate 5 is not rotated, the rotating plate 5 can completely cover the first groove 3. The upper surface of the rotating plate 5 is also on the same horizontal plane as the upper surface of the panel 1, facilitating the patient to lie flat. A first sliding groove 6 is formed in the first groove 3 and the second groove 4 together. A lead screw 7 is rotatably connected in the first sliding groove 6. The lead screw 7 is also rotatably connected in the panel 1. A first slider 8 is slidably connected in the first sliding groove 6. The first slider 8 is threadedly connected to the lead screw 7.

The left end of the push rod 32 passes outside the inflation cylinder 30 and is fixedly connected to a semi-circular pull handle 33. Two through holes are provided on the left side wall of the inflation cylinder 30. A first one-way valve 34 is installed in the upper through hole. When the first one-way valve 34 is opened, gas can only flow from the inflation cylinder 30 to the outside. The first one-way valve 34 is externally connected to an intake pipe 36. The right end of the intake pipe 36 penetrates into the placement groove 11 and is communicated with the flexion and extension airbag 12. A second one-way valve 35 is installed in the lower through hole. When the second one-way valve 35 is opened, gas can only flow from the outside into the inflation cylinder 30; A deflation valve 20 is installed on the rear side of the panel 1 through bolts. The deflation valve 20 is communicated with a deflation pipe 37. The right end of the deflation pipe 37 penetrates into the placement groove 11 and is communicated with the flexion and extension airbag 12.

[0033] At the tail of the panel 1, there is a foot massage mechanism. The foot massage mechanism includes two foot sleeves 21 and an installation part 22. The two foot sleeves 21 are placed on the panel 1. The two foot sleeves 21 are sewn with a double-layer elastic non-woven fabric 23. There is a massage airbag 24 between the two layers of elastic non-woven fabric 23. The shape of the massage airbag 24 is the same as that of the foot sleeve 21, and the massage airbag 24 fills the space between the two layers of elastic non-woven fabric 23; the installation part 22 is a square shell structure with a hollow interior. The installation part 22 is fixed to the tail of the panel 1. A cylinder 25 is fixed in the installation part 22 by bolts. The preset time for the piston rod 27 of the cylinder 25 to push forward is two seconds. After two seconds, the piston rod 27 resets. The cylinder 25 moves in such a cycle. The control button 29 of the cylinder 25 is installed on the side of the panel 1 on the same side as the air release valve 20, which is convenient for the patient to control the opening and closing of the cylinder 25 by himself; a bellows 26 is fixed on the piston rod 27 of the cylinder 25. The side of the bellows 26 away from the cylinder 25 is fixed on the side wall inside the installation part 22. The bellows 26 is filled with inert gas. The side of the bellows 26 away from the cylinder 25 is also connected with an air injection pipe 28. The free end of the air injection pipe 28 extends outside the installation part 22 and is connected to the two massage airbags 24 through two branch pipes respectively.

[0034] The working principle of this technical solution: When the device is in the non-working state, the rotating plate 5 is in the first groove 3, the sealing plate 13 is in the second groove 4, and the pressing foot mechanism is at the leftmost end of the panel 1. The device can be used as an ordinary bed for the patient to lie flat and rest; when the patient needs to exercise, first use the elastic band 38 to fix the thigh part, and then turn the handle 19. The handle 19 drives the turntable 18 to rotate. The turntable 18 drives the lead screw 7 to rotate through the second bevel gear 17, the connecting rod 16 and the first bevel gear 15. The rotation of the lead screw 7 drives the first slider 8 to slide to the left, so that the support rod 10 lifts the rotating plate 5, thereby tilting and lifting the patient's thigh; at the same time, the rotation of the lead screw 7 also drives the second slider 9 to move to the left, thereby driving the sealing plate 13 to move to the left, thus opening the placement groove 11; then continuously push and pull the handle 33 of the inflation mechanism to inflate the flexion and extension airbag 12, and use the flexion and extension airbag 12 to lift the calf part as well. When the flexion and extension airbag 12 is completely filled with air, the calf and the thigh are on the same straight line. Then the patient can deflate the flexion and extension airbag 12 regularly and quantitatively according to the pain degree of his own knee joint, so that the calf bends again, so as to achieve the effect of flexing and extending the knee joint. The device does not require the assistance of others, and the patient can plan the exercise time and frequency according to his own situation.

[0035] When the patient is doing flexion and extension exercises, the foot sleeve 21 can also be put on the foot, and then the control button 29 of the air cylinder 25 is activated, so that the massage airbag 24 inflates and deflates to cyclically press on the sole and instep of the patient's foot, playing a massage role on the patient's foot. In this way, in cooperation with the knee joint flexion and extension movement, it can promote the patient's blood circulation, further reduce the probability of complications such as thrombosis, and at the same time can also accelerate the patient's recovery speed.

[0036] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
