Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation technology, specifically to an auxiliary device for rehabilitation training of lumbar muscle strain. Background Technology

[0002] Lumbar muscle strain refers to the cumulative damage to the muscles of the lower back and their attachment points, causing local chronic aseptic inflammation, with the main clinical manifestations being dull pain in the lower back, recurrent attacks, and aggravation after exertion.

[0003] For rehabilitation training of lumbar muscle strain, exercises such as the "flying swallow" and "five-point support" can be used. When exercising the lumbar region with the five-point support, the patient uses the two legs, two elbows, and the back and neck (or head) as five support points. During the exercise, the patient bends their legs and lies flat on the bed with their buttocks and head flat. The patient uses their legs, waist, and back to lift their buttocks so that the whole body is in an "arch" shape for support. At this time, the patient's body is supported by the soles of their feet, two elbows, and the back and neck (or head), thus completing the five-point support training. Because the patient's lumbar region is already injured, it is difficult for them to complete the five-point support training on their own.

[0004] Patent CN109126035B discloses a rehabilitation device for lumbar muscle strain, comprising a base, a curved foot plate, a slider mechanism, a guide tube, a double-sided ratchet, a leg support plate, an L-shaped perforated plate, a wedge block, a plug rod, a first spring, a support plate, a guide rod, a second spring, a support frame, and a back support plate. A groove is formed in the middle of the base, and a first groove is evenly formed at the bottom of the groove, communicating with the groove. A curved foot plate is located on the top right side of the base. Three slider mechanisms are slidably arranged within the groove, and a guide tube is located on the top of the right slider mechanism. The inner movable type is equipped with a double-sided ratchet, and a support plate is provided at the top of the double-sided ratchet. L-shaped perforated plates are provided at the upper ends of both sides of the guide tube. Insertion rods are movable within the L-shaped perforated plates. A wedge-shaped block is symmetrically positioned at the right end of the left insertion rod and the left end of the right insertion rod. The right side of the left wedge-shaped block passes through the left wall of the guide tube and contacts the left side of the double-sided ratchet, while the left side of the right wedge-shaped block passes through the right wall of the guide tube and contacts the right side of the double-sided ratchet. A first spring is connected to the right side of the left L-shaped perforated plate and the left side of the right L-shaped perforated plate. The right end of the left first spring is connected to the left side of the left wedge-shaped block, and the left end of the right first spring is connected to the right wedge-shaped block. The block is connected to the right side, and a support plate is provided on the top of the left slider mechanism. Guide rods are provided on both the left and right sides of the top of the support plate. A second spring is connected to the lower part of the guide rods. A support frame is movable on the left and right guide rods. The upper end of the second spring is connected to the bottom of the support frame. A back support plate is rotatably provided on the support frame. When people need to perform rehabilitation training, they sit on the leg support plate 6, hook their feet onto the curved foot presser plate 2, and then lie on the back support plate 14. After lying down, they use their hands to support their lower back and move it up and down. This facilitates lower back exercises. This patent aims to alleviate the symptoms of lumbar muscle strain. In this design, after the patient lies down, their buttocks are higher than their feet, placing them in a high position for five-point support. This makes it difficult to move the lower back up and down for exercise. Furthermore, during self-exercise, the patient needs to place their feet on the ground and exert force with their calves. The patient's thighs are on a leg support board, and the angle between the thighs and calves is difficult to change (the leg support board is located in the popliteal fossa), preventing the buttocks from moving up and down. Additionally, the patient's calves have difficulty exerting force, making it difficult for the patient to perform five-point support exercises for the lower back using a combination of self-exercise and passive training.

[0025] Preferably, the bottom frame 101 is a rectangular frame formed by welding steel, and the lower end of the bottom frame 101 is provided with four sets of support feet 105.

[0026] Preferably, eight pillars 102 are provided, and four pillars 102 are divided into groups and installed at both ends of the bottom frame 101. The first top frame 103 and the second top frame 104 have the same shape as the bottom frame 101. The first top frame 103 is installed on one group of four pillars 102, and the second top frame 104 is installed on another group of four pillars 102.

[0027] Preferably, two sets of the first slide rail 5 and the second slide rail 6 are provided respectively, with the two sets of the first slide rail 5 symmetrically installed at both ends of the first top frame 103; and the two sets of the second slide rail 6 symmetrically installed at both ends of the second top frame 104.

[0028] Preferably, the buffer 14 is a spring.

[0029] In the above configuration, by setting the first top frame 103 and the second top frame 104, three spaces are divided on the support bed 1, and the mounting cavity 7 is formed between the first top frame 103 and the second top frame 104. At this time, the back support plate 2, the hip support plate 3, and the leg support plate 4 are also divided into three sections.

[0030] Further, see Figure 1 The bottom end of the back support plate 2 is provided with a first sliding groove 15, which is slidably connected to the first slide rail 5; the first locking member includes a first locking stud.

[0031] Preferably, the back support plate 2 is provided with a first screw hole, which passes through the first sliding groove 15.

[0033] In the above configuration, the back support plate 2 is slidably installed on the first slide rail 5 by connecting the first slide groove 15 to the first slide rail 5. By moving the position of the back support plate 2 on the first slide rail 5, it can adapt to different users. The position of the back support plate 2 on the first slide rail 5 is fixed by rotating the first locking stud to abut against the first slide rail 5.

[0034] Further, see Figure 1 The back support plate 2 is provided with a first adjustment groove 16, and a shoulder support 17 is movably provided in the first adjustment groove 16.

[0035] Preferably, the first adjustment groove 16 is perpendicular to the first sliding groove 15, and the first adjustment groove 16 is divided into two sections on the back support plate 2, with one end of the first adjustment groove 16 penetrating through the edge of the back support plate 2; two sets of shoulder supports 17 are provided.

[0036] Preferably, the back support plate 2, the hip support plate 3, and the leg support plate 4 are all provided with a leather-wrapped sponge layer.

[0037] In the above setup, the patient's back is positioned on the back support plate 2. Adjusting the patient's back allows the patient's shoulders to be close to the shoulder support 17. The shoulder support 17 can then slide within the first adjustment groove 16, pressing the shoulder support 17 against the patient's shoulders to provide support.

[0038] Further, see Figure 1 The hip support plate 3 is provided with an outward protruding pad 18; the back support plate 2, the hip support plate 3, and the leg support plate 4 are respectively provided with elastic stretching layers 19.

[0039] Preferably, the convex pad 18 has a semi-circular structure and is made of leather wrapped with sponge.

[0040] Preferably, there are gaps between the back support plate 2 and the hip support plate 3, and between the hip support plate 3 and the leg support plate 4. The elastic stretching layer 19 is made of rubber and covers the gaps between the back support plate 2, the hip support plate 3, and the leg support plate 4.

[0041] In the above configuration, as the hip support plate 3 moves upward, the patient's hip moves upward as well, and the outward convex pad 18 can provide support for the patient's hip. At the same time, the outward convex pad 18 is depressed under pressure, which can support the patient's hip and prevent the edge of the hip support plate 3 from squeezing the patient's waist and causing discomfort. When the back support plate 2 and the leg support plate 4 move relative to the hip support plate 3, the elastic stretching layer 19 stretches or shortens.

[0042] Further, see Figure 1 The bottom end of the leg support plate 4 is provided with a second sliding groove 20, which is slidably connected to the second slide rail 6; the second locking member includes a second locking stud; the leg support plate 4 is provided with a leg support pad 21 and a palm support pad 22 at an angle, the angle of the leg support pad 21 is towards the buttock support plate 3, and the angle of the palm support pad 22 is away from the buttock support plate 3.

[0043] Preferably, the leg support plate 4 is provided with a second screw hole, which passes through the second sliding groove 20.

[0044] Preferably, the second locking stud is connected to the second threaded hole via threads.

[0045] Preferably, the leg support pad 21 includes a leg support plate fixedly connected to the leg support plate 4, sponge and leather wrapped around the leg support plate, and the length of the leg support pad 21 is between 20cm and 30cm.

[0046] Preferably, the palm support pad 22 is made of leather wrapped with sponge, and the palm support pad 22 is higher than the upper surface of the leg support plate 4.

[0047] In the above setup, the leg support pad 21 provides support for the patient's lower legs, and the palm support pad 22 provides support for the patient's feet, making it easier for the patient to exert force with their lower legs.

[0048] Further, see Figure 1 The mounting cavity 7 is provided with a bottom support plate 23; the lifting component 10 includes a lifting motor mounted on the bottom support plate 23; the transmission component 12 includes a transmission wheel mounted on the lifting motor; the reciprocating component 11 includes a sliding frame 24 set on the bottom support plate 23 and a rack 25 slidably mounted in the sliding frame 24; the transmission wheel meshes with the rack 25.

[0049] Preferably, the lifting motor has an existing structure, and the lifting motor is a self-locking motor, so the shaft cannot be rotated arbitrarily.

[0050] Preferred, see Figure 2 The sliding frame 24 is a hollow rectangular body with openings at both ends. The side wall of the sliding frame 24 is provided with a drive groove 26, and the transmission wheel passes through the drive groove 26 to mesh with the rack 25.

[0051] Preferred, see Figure 1 A connecting rod 27 is provided between the first top frame 103 and the second top frame 104, and a through hole is provided on the connecting rod 27; a positioning rod that slides within the through hole is provided on the hip support plate 3.

[0052] Preferably, the lifting motor is equipped with a control button 28, which has several positions. When it is in the middle position, the power is off; when it is in the front position, the power for forward rotation of the lifting motor is on; and when it is in the rear position, the power for reverse rotation of the lifting motor is on. Limit switches 29 are respectively provided on the sliding frame 24 and the bottom support plate 23, and protrusions 30 are provided on the rack 25. When the rack 25 contacts the limit switch 29 on the support plate, the hip support plate 3 contacts the connecting rod 27.

[0053] In the above setup, pressing the control button 28 forward to the front end connects the forward power supply to the lifting motor, causing it to rotate forward. The transmission wheel rotates accordingly, driving the rack 25 upward. After the telescopic rod 13 shortens, it drives the hip support plate 3 upward, allowing the patient's hips to move upward and form a five-point support exercise for the patient's waist. The protrusion 30 moves upward and contacts the limit switch 29 on the sliding frame 24, disconnecting the power supply to the lifting motor. This controls the highest point of the rack 25's upward movement, which is also the highest point of the hip support plate 3's upward movement. When the control button 28 is at the rear end, the lifting motor drives the rack 25 downward, and the hip support plate 3 moves downward accordingly. The lifting motor is a geared motor with controllable rotation speed. After the rack 25 moves downward and contacts the limit switch 29 on the support plate, the power supply to reverse the lifting motor is disconnected, and the lifting motor stops working. The hip support plate 3 is located on the connecting rod 27.

[0054] In this embodiment, when the patient performs lumbar training, they first sit on the hip support board 3, with their feet on the footrests and their back on the back support board 2, and the shoulder support 17 supporting their shoulders, so that the patient's body is positioned on the support bed 1. Passive training can be performed according to the patient's condition. After the lifting motor is powered on, the lifting motor rotates and drives the rack 25 to move upward, and the hip support board 3 moves upward to lift the patient's hips. The patient's back and legs are supported on the back support board 2 and the leg support board 4 respectively, completing five-point support for the waist. When the patient performs active training combined with passive training, they can exert force in their legs, back, and waist at the same time as the hip support board 3 moves upward to lift their hips to form five-point support. By controlling the duration of the lifting motor's power supply, the upward height of the rack 25 can be controlled, thereby controlling the height to which the patient's hips are lifted to adapt to different training requirements.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
