Description

Technical Field

[0001] The invention relates to a rehabilitation training device, in particular to a rehabilitation training device for intertrochanteric fracture of the femur. Background Art

[0002] Intertrochanteric fracture refers to a fracture that occurs at the upper end of the femur, near the hip joint. This type of fracture is common in the elderly, especially in falls caused by osteoporosis. During the treatment process, patients need to undergo regular rehabilitation training to help them recover their function.

[0003] During the treatment process, patients usually lie on the hospital bed and then manually perform calf lifting exercises and limb flexion and extension functional exercises. Fracture trauma and postoperative pain can cause reflex inhibition of the patient's muscles. Muscle reflex inhibition can make it difficult for the patient to effectively exert muscle strength and limit active movement ability, affecting the patient's rehabilitation training, making it difficult to achieve the expected rehabilitation training effect. Summary of the Invention

[0004] In order to overcome the shortcomings that muscle reflex inhibition makes it difficult for patients to effectively exert their muscle strength, limit their active movement ability, affect their rehabilitation training, and thus make it difficult to achieve the expected rehabilitation training effect, the present invention provides a rehabilitation training device for intertrochanteric fractures.

The top of the bed frame is connected to the bed board, the top of the bed board is connected to the mattress, the side of the bed board is hinged with a backboard, the top of the bed board is hinged with two first placement boards for placing thighs and two second placement boards for placing calves, the top of the bed board is connected to two first slide rails, and the first slide rails are slidably connected to the second A slider, the first slider is connected to the first lifting roller, two mounting frames are connected to the bed frame, electric slide rails are installed on the mounting frames, servo motors are installed on the sliding blocks of the electric slide rails, and driving wheels are connected to the output shafts of the servo motors. The bottoms of the driving wheels are all arc-shaped surfaces. The driving wheels are used to push the first lifting roller to move upward. The first lifting roller lifts the patient's calf for calf lifting rehabilitation training. A flexion and extension mechanism is provided on the bed board for training the patient's limb flexion and extension function, and a massage mechanism is provided on the bed frame for massaging the patient's legs.

[0006] Further explanation: the flexion and extension mechanism includes a second slide rail, a second slider, a second lifting roller, a contact rod and a lifting assembly. Two second slide rails are connected to the top of the bed board. The second slide rails are slidably connected to the second sliders. The second sliders are connected to the second lifting rollers. The pushing wheels can push the second lifting rollers to move upward. The second lifting rollers lift the patient's knee joints to perform limb flexion and extension function training. The first placement plate and the second placement plate are both connected to contact rods, which are in contact with the second lifting rollers. The sliding block of the electric slide rail is provided with a lifting assembly for allowing the patient to sit up.

[0012] It is further explained that both the front and rear sides of the mattress are provided with notches for accommodating the first placement board and the second placement board.

[0013] The beneficial effects are: 1. The present invention can push the first lifting roller upward through the pushing wheel, lift the patient's calf, perform calf lifting rehabilitation training, and help the patient recover function. The pushing wheel can also push the second lifting roller upward, and the second lifting roller lifts the patient's knee joint to perform limb flexion and extension function training. The entire training process is carried out automatically, so that the expected rehabilitation training effect can be better achieved.

[0014] 2. The contact plate can be pushed downward by the pushing wheel, and the contact plate drives the piston block to move downward. The piston block pushes the air in the piston cylinder. The air in the piston cylinder enters the airbag through the trachea to expand the airbag. The airbag can squeeze the patient's legs and massage the patient's legs, promote local blood circulation, help blood flow better, reduce blood retention, and thus reduce the risk of thrombosis.

[0015] 3. The push plate can push the slide plate upward, the slide plate drives the guide block upward, and the guide block drives the back plate to rotate upward, so that the patient can sit up, which can effectively increase the range of motion of the joints, improve the flexibility of the joints, and prevent joint stiffness.

The first placement plate 5 and the second placement plate 6 are connected to the contact rod 19, and the contact rod 19 is in contact with the second lifting roller 18. The sliding block of the electric slide rail 11 is provided with a lifting assembly for making the patient sit up.

[0028] like Figure 4 and Figure 5 As shown, the lifting assembly includes a guide rail 20, a guide block 21, a guide plate 22, a slide plate 23 and a push plate 24. The right side of the bottom of the support plate 4 is connected to the guide rail 20 by bolts, and the guide block 21 is slidably connected to the guide rail 20. The right side of the bottom of the support plate 4 is connected to the guide plate 22 by bolts. The guide plate 22 is located below the guide rail 20. The middle part of the guide plate 22 is slidably connected to the slide plate 23. The top of the slide plate 23 and the bottom of the guide block 21 are hingedly connected. A push plate 24 is connected between the sliding blocks of the two electric slide rails 11, and the left part of the push plate 24 is tilted downward.

[0029] like Figure 6 and Figure 7 As shown, the massage mechanism includes an airbag 25, a piston cylinder 26, a piston block 27, a spring 28, an air pipe 29, a slide rod 30 and a contact plate 31. The airbags 25 are connected to the first placement plate 5 and the second placement plate 6. The front and rear sides of the lower part of the bed frame 1 are connected to the piston cylinder 26 by bolts. The piston cylinder 26 is sealed and slidably connected with the piston block 27. A spring 28 is connected between the bottom of the piston block 27 and the bottom of the piston cylinder 26. Two air pipes 29 are connected to the bottom of the piston cylinder 26. The four air pipes 29 are respectively connected to the four airbags 25, and the air pipes 29 are connected to the airbags 25. The top of the piston block 27 is connected to the slide rod 30, which slides through the top of the piston cylinder 26. The upper end of the slide rod 30 is connected to the contact plate 31, and the right part of the contact plate 31 is tilted downward.

[0030] like Figure 8 As shown, it also includes a connecting frame 32 and a support plate 33. The lower part of the bed frame 1 is connected to the connecting frame 32 by bolts, and the top of the connecting frame 32 is connected to the support plate 33 by bolts. The bottom of the push plate 24 is in contact with the top of the support plate 33.

[0031] like Figure 1 As shown, it also includes a first guardrail 34 and a second guardrail 35. The first guardrail 34 is connected to the front and back sides of the top of the backrest 4, and the second guardrail 35 is connected to the front and back sides of the top of the bed board 2.

[0032] like Figure 1 As shown, the bed frame 1 also includes universal wheels 36, which are symmetrically installed on the front and back sides of the bottom of the bed frame 1.

[0033] The medical staff pushes the bed frame 1 and moves it to the designated position. The universal wheel 36 can reduce friction, making it easier for the medical staff to push the bed frame 1. The patient sits on the mattress 3, then lies on the backrest 4, places the thighs in the first placement board 5, and places the calves in the second placement board 6. The airbag 25 contacts the patient's legs, and the first lifting roller 9 and the second lifting roller 18 are both located below the patient's legs. The output shaft of the servo motor 12 drives the pushing wheel 13 to rotate, and the pushing wheel 13 pushes the first lifting roller 9 to move upward, and the first lifting roller 9 lifts the patient's calf. When the curved surface 14 of the pushing wheel 13 contacts the first lifting roller 9, the first lifting roller 9 stops moving upward, so that the patient's calf can remain lifted. The curved surface 14 of the pushing wheel 13 and the first lifting roller 9 When one lifting roller 9 gradually disengages from contact, the first lifting roller 9 moves downward under the action of its own gravity, putting down the patient's calf, and repeating this process. The patient's calf can be frequently lifted and lowered to perform calf lifting rehabilitation training and help the patient recover function. When calf lifting training is not needed, the servo motor 12 is turned off, and the arc surface 14 of the pushing wheel 13 is facing downward. Then, the electric slide rail 11 is controlled to drive the servo motor 12, the pushing wheel 13 and the pushing plate 24 to move to the left, and the pushing wheel 13 is moved to the bottom of the second lifting roller 18, so that the pushing wheel 13 can push the second lifting roller 18, and the left part of the pushing plate 24 is tilted downward. The tilted position of the pushing plate 24 can push the slide plate 23 to move upward, and the slide plate 23 drives the guide block 21 to move upward. The guide block 21 moves upward in the guide The guide block 21 can drive the backrest 4 to rotate upwards, so that the patient sits up and leans on the backrest 4. The connecting frame 32 and the support plate 33 can support the push plate 24, thereby supporting the backrest 4 and improving the stability of the backrest 4. The first guardrail 34 and the second guardrail 35 can stop the patient to prevent the patient from falling from the bed board 2. The right part of the contact plate 31 is tilted downward. When the pushing wheel 13 moves to the left and contacts the tilted position of the contact plate 31, the pushing wheel 13 can push the contact plate 31 to move downward. The contact plate 31 drives the slide rod 30 and the piston block 27 to move downward. The spring 28 is compressed, and the piston block 27 pushes the air in the piston cylinder 26. The air in the piston cylinder 26 enters the airbag 25 through the trachea 29, causing the airbag 25 to expand. The airbag 25 can squeeze the patient's legs and start the servo motor 12 again. The output shaft of the servo motor 12 drives the driving wheel 13 to rotate. The driving wheel 13 drives the second lifting roller 18 to move upward. The second lifting roller 18 lifts the patient's knee joint. When the arc surface 14 of the driving wheel 13 contacts the second lifting roller 18, the second lifting roller 18 stops moving upward, so that the patient's knee joint can remain in a lifted state. When the arc surface 14 of the driving wheel 13 and the second lifting roller 18 gradually lose contact, the second lifting roller 18 moves downward under the action of its own gravity, lowering the patient's knee joint. This reciprocating process can frequently lift and lower the patient's knee joint to perform limb flexion and extension function training, and the patient is sitting on the mattress 3 for training.It can effectively increase the range of motion of the joints, improve the flexibility of the joints, and prevent joint stiffness. The entire training process is carried out automatically, so that the expected rehabilitation training effect can be better achieved. At the same time, the second lifting roller 18 moves upward to push the contact rod 19, causing the contact rod 19 to rotate upward. The contact rod 19 drives the first placement plate 5 and the second placement plate 6 to rotate upward, so that the first placement plate 5 and the second placement plate 6 can support the patient's thighs and calves, avoiding the patient's thighs and calves being suspended in the air and causing the patient to feel uncomfortable. The pushing wheel 13 will disengage from the contact plate 31 when pushing the second lifting roller 18 The push wheel 13 no longer pushes the contact plate 31. Under the action of the spring 28, the piston block 27 moves upward, and the air in the airbag 25 flows back into the piston cylinder 26 through the trachea 29. The airbag 25 returns to its original state. The push wheel 13 continues to rotate, and the push wheel 13 pushes the contact plate 31 downward again, allowing the air in the piston cylinder 26 to enter the airbag 25 through the trachea 29, causing the airbag 25 to expand. The airbag 25 squeezes the patient's leg again, thereby massaging the patient's leg, promoting local blood circulation, helping blood flow better, reducing blood retention, and thus reducing the risk of thrombosis.
