Description

Technical Field

[0001] The invention relates to the field of medical beds, in particular to a multifunctional spinal traction bed. Background Art

[0002] At present, my country is facing the social pressure of entering an aging society. It is predicted that the number of elderly people aged 60 and above will exceed 300 million around 2025. With the increase of the elderly population, diseases will follow. Relevant surveys show that 97% of the middle-aged and elderly people in my country suffer from spinal diseases, and in recent years, the trend has become younger. Among people under 40 years old, more than 40% have various spinal diseases. According to statistics from the China Child Development Center, the incidence of scoliosis in children is as high as 20%. According to statistics from the Beijing University of Chinese Medicine, 80% of adults with headaches, back pain, and numbness of hands and feet actually come from spinal abnormalities in childhood. With the continuous development of our society, office white-collar workers, students and teachers, etc., due to the long-term lack of effective exercise and long-term sitting, long-term accumulation will cause spinal injuries. In addition, waist injuries have also long-term effects on the lives of motor vehicle drivers.

[0003] For example, Chinese patent CN116439890A discloses a multifunctional spinal traction bed, including a bed frame, a cervical traction mechanism, a lumbar traction mechanism and a supporting mechanism. The invention has a reasonable structural design, and the bed frame is divided into three parts: head, back and leg. The cervical traction mechanism and the lumbar traction mechanism can be used to perform corresponding traction treatments on the cervical and lumbar vertebrae. Specifically, three rotating motors and four electric cylinders are used to realize the traction system's cervical up-down and rotational traction, lumbar up-down and rotational traction, and spine stretching traction; multifunctional traction is realized, the treatment effect is greatly improved, and it has good market value; each traction effect is controlled by a computer, which reduces the consumption of manpower, and has the advantages of simple structure, low cost and easy operation.

[0004] With regard to spinal traction beds, most of the conventional traction beds nowadays use a hand wheel rotated by a caregiver to traction the position of the spine, so as to facilitate traction of the patient's spine. However, a multifunctional spinal traction bed, such as the one mentioned in the comparative document, traction of the spine is performed by computer control, which reduces the consumption of manpower, but the computer control still requires the caregiver to be around. If the caregiver is not there, the spine cannot be pulled if the caregiver wants to, and the intensity of the spinal traction cannot be adjusted according to the patient's comfort. Therefore, in view of the above problems, a multifunctional spinal traction bed is proposed. Summary of the invention

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a multifunctional spinal traction bed, which has the following beneficial effects:

[0022] 1. This multifunctional spinal traction bed adds a spinal lifting device and a self-adjusting device to the bed. Through the cooperation of the two devices, the patient can start the spinal lifting device through the self-adjusting device in the absence of a caregiver, thereby achieving a traction effect on his own spine, reducing labor and saving costs.

[0023] 2. This multifunctional spinal traction bed uses a self-adjusting device and a foot pedal is placed at the end of the bed. The patient can adjust it according to his or her own on-site environment, and can also complete the jacking force of the spinal jacking device according to his or her own comfort, so as to avoid the accompanying personnel being unaware of the patient's comfort during traction, which may cause further damage to the patient.

[0024] 3. This multifunctional spinal traction bed uses a self-adjusting device and pedals. Since the patient has spinal problems and needs to lie in bed for a long time, the other parts of the body cannot move. After the patient activates the self-adjusting device by pedaling, he can not only traction his spine, but also step on it as if walking on the ground, and move other parts of his body, thus avoiding atrophy caused by long-term inactivity of other parts of the body.

[0025] 4. This multifunctional spinal traction bed is located at the lower end of the bed through a spinal lifting device, and the support at the lower end of the mattress is lifted up by a push rod, thereby achieving spinal traction. The push rod is raised and lowered mechanically to reduce the operating steps, simplify the machinery, and reduce the cost of computerization.

[0026] 5. This multifunctional spinal traction bed uses a spinal lifting device to utilize the spiral block on the back of the turntable to engage with the tooth groove on the side end of the push rod. According to the rotation of the spiral block, the spacing between the spiral blocks drives the tooth groove to move, thereby forming the lifting and lowering of the push rod. The spacing between the tooth grooves is tiny. Therefore, the lifting and lowering range of the push rod is very small in this way, avoiding excessive traction and causing damage to the patient's spine.

[0027] 6. The multifunctional spinal traction bed is provided with a movable seat at the side end of the turntable, and the movable seat is extended to the side end of the bed by an adjusting rod, so that when traction is needed, the spiral block and the top rod can be manually turned to be in a clamping state, so that the top rod has the support of the spiral block. When traction is not needed, the two can be separated by manual turning, so that the top rod loses the support of the spiral block and thus descends, which is convenient for the patient's operation.

[0028] 7. The multifunctional spinal traction bed can realize the connection between devices through the hands and the activation between devices through the feet, so as to realize the movement of the patient on the bed and avoid the loss of body function. BRIEF DESCRIPTION OF THE DRAWINGS

When the patient needs to pull his spine up and there is no accompanying person nearby, he needs to operate it himself, and the patient uses his feet to step on the foot pedal 6, and the stepping of the two foot pedals 6 will be started by the self-adjusting device, so that the self-adjusting device starts the spinal jacking device, and the started spinal jacking device drives the push rod 9 to lift the supporting seesaw 2, so that the patient's spine is pulled after the supporting seesaw 2 is tilted.

[0044] The spine lifting device includes a turntable 10, a gear 11, a rotating shaft 12, a rod sleeve 13, a swing rod 14, a tooth hook 15 and a bracket sleeve 16. The upper end of the supporting frame 8 is provided with a turntable 10 corresponding to the side end of the push rod 9, and the side end of the turntable 10 is fixedly connected with the rotating shaft 12, and the turntable 10 is fixedly connected with the gear 11 at one end of the rotating shaft 12, and the rod sleeve 13 is movably connected to the rotating shaft 12, and the swing rod 14 is fixedly connected to one side of the rod sleeve 13, and the tooth hook 15 is fixedly connected to one side of the rod sleeve 13, and the back side of the turntable 10 is movably connected with the bracket sleeve 16, and the inside of the bracket sleeve 16 is provided with the push rod 9.

[0045] The tooth hook 15 is arranged in a U shape, and the two ends of the tooth hook 15 correspond to the gear 11 and the rod sleeve 13 respectively, and the end of the tooth hook 15 corresponding to the gear 11 is arranged as an inclined surface, and the end of the tooth hook 15 corresponding to the rod sleeve 13 is provided with a U-shaped groove 16, and the position of the rod sleeve 13 corresponding to the U-shaped groove 16 is fixedly connected with a fixing block 17, and the fixing block 17 is movably connected with the U-shaped groove 16, and a blocking block 18 is fixedly connected to one side of the fixing block 17, and the swing rod 14 and the fixing block 17 are located on the rod sleeve 13 and are arranged at a fixed right angle.

[0046] The bracket sleeve 16 is in an inclined quadrilateral shape, and a slider 19 is fixedly connected to the inner wall of the bracket sleeve 16 , and two slide grooves 20 are opened at the side end of the push rod 9 , and the slide grooves 20 and the slider 19 are movably connected together.

[0047] A spiral block 21 is fixedly connected to the back of the turntable 10, and a tooth groove 22 is opened on one side of the top rod 9, and the spacing between the spiral blocks 21 corresponds to the spacing of the tooth grooves 22, and the spiral block 21 and the tooth grooves 22 are clamped together. When the self-adjusting device drives the spinal traction device to start, it will drive the swing rod 14 to swing up and down around the rotating shaft 12, and the swing rod 14 is connected to the rod sleeve 13. After the swing rod 14 swings, the rod sleeve 13 is rotated slightly, and a fixed block 17 is provided on the rod sleeve 13, and a tooth hook 15 is provided on the fixed block 17. After rotating clockwise, the tooth hook 15 will be blocked by the blocking block 18, and the tooth hook 15 will be blocked by the blocking block 18. 5 will not rotate to the side, therefore, after the rod sleeve 13 rotates clockwise, it will drive the tooth hook 15 to clamp the gear 11, so that the tooth hook 15 drives the gear 11 to rotate, and after the gear 11 rotates, it will drive the turntable 10 to rotate, and the rotation of the turntable 10 will drive the spiral block 21 on the back to rotate, and the spacing of the spiral block 21 corresponds to the tooth groove 22 on the push rod 9. After the spiral block 21 rotates, the tooth groove 22 will gradually rise along the spacing of the spiral block 21, so that the push rod 9 is gradually lifted up, and the lifting of the push rod 9 is used to lift the support rocker 2, so that the mattress 4 forms an angle, so that the spine can be lifted up.

[0048] The outer end of the turntable 10 is movably sleeved with a moving seat 34, and the moving seat 34 is movably connected to the supporting frame 8, and an adjusting rod 35 extends from the side end of the moving seat 34, and the adjusting rod 35 is arranged in an L shape, and one end of the adjusting rod 35 passes through the side end of the bed body 1 and extends to the upper end. When it is necessary to put down the top rod 9, the adjusting rod 35 is moved to the side end at the edge of the bed body 1 by the hand position, so that the adjusting rod 35 drives the moving seat 34 to move to the side end, so that the moving seat 34 drives the turntable 10 to move to the side end. At this time, the turntable 10 will drive the bracket sleeve 16 to move to the side end, so that the slider 19 at the side end of the bracket sleeve 16 disengages from the original slide groove 20 and moves to the slide groove 20 on the other side. At this time, the spiral block 21 is also disengaged from the tooth groove 22. Without the support of the spiral block 21, the tooth groove 22 on the top rod 9 will also lose its supporting force, causing the top rod 9 to fall, thereby restoring the mattress 4 to its original state.

[0049] The self-adjusting device includes a first rotating rod 23, a second rotating rod 24 and a connecting assembly. The first rotating rod 23 is movably inserted on the inner wall of the protective box 7, and the second rotating rod 24 is movably inserted on the other end of the inner wall of the protective box 7, and the first rotating rod 23 and the second rotating rod 24 are movably connected together, and two groups of connecting assemblies are arranged inside the protective box 7 at positions corresponding to the first rotating rod 23 and the second rotating rod 24, and one end of the two foot pedals 6 extends into the interior of the protective box 7, and the two foot pedals 6 are fixedly connected to the first rotating rod 23 and the second rotating rod 24, respectively.

[0050] The two groups of connecting components include a sleeve 25, a movable sleeve 26, a connecting plate 27, a connecting shaft 28 and a second connecting plate 29. The two sleeves 25 are respectively fixedly connected to the first rotating rod 23 and the second rotating rod 24, and the upper ends of the two sleeves 25 are fixedly connected with the movable sleeve 26, and two connecting shafts 28 are movably connected to the inner wall of the protective box 7. The two ends of the two connecting shafts 28 are respectively fixedly connected with the connecting plate 27 and the second connecting plate 29, and the other ends of the two adjacent second connecting plates 29 are movably connected together through columns. The two connecting shafts 28 are respectively located on both sides of the first rotating rod 23 and the second rotating rod 24.

[0051] A limiting groove 30 is formed at one end of the two movable sleeves 26 , and the outer ends of the two connecting plates 27 are fixedly connected to the limiting pillars 31 , and the two limiting pillars 31 are movably connected with the limiting grooves 30 .

[0052] One side of the protection box 6 is provided with a connecting groove 32 at the upper and lower ends, and a connecting plate 33 is arranged in the connecting groove 32, and one end of the connecting plate 33 is movably connected to one end of the swing rod 14, and one end of the connecting plate 33 located inside the protection box 6 is movably connected to the position where the two second connecting plates 29 are connected. When the patient needs to adjust the spinal traction part, he first steps on the foot pedal 6 with his feet. After stepping on the foot pedal 6, the first rotating rod 23 and the second rotating rod 24 are driven to rotate. When the first rotating rod 23 is stepped on, the connecting assembly is driven to start, and the connecting assembly is rotated by the shaft sleeve 25 along with the rotation of the first rotating rod 23, and the rotation of the shaft sleeve 25 drives the movable sleeve 26 to rotate, and after the movable sleeve 26 swings, the internal limiting column 31 moves in the limiting groove 30 along with the swing of the movable sleeve 26, and the rotation of the movable sleeve 26 drives the connecting plate 27 to swing, and the connecting plate 27 The second connecting plate 29 is fixed with the connecting plate 27 by the connecting shaft 28. Therefore, after swinging, the connecting plate 27 will rotate around the connecting shaft 28, so that the second connecting plate 29 at the other end will also swing up and down with the rotation of the connecting plate 27. When the connecting component at this end is started, the connecting component at the other symmetrical end will also be started. After stepping on the pedal 6 at one end, the pedal 6 at the other end will swing in the opposite direction due to the symmetry of the two groups. After the two groups of connecting components are started, the two second connecting plates 29 will swing up and down, and after swinging, the connecting plate 33 will be driven to move up and down, so that the swing rod 14 is started by the connecting plate 33. After the self-adjusting device is started, the movement trajectory of the two foot pedals 6 will form a walking movement, thereby exercising the legs and preventing the patient from lying in bed for a long time and causing muscle paralysis in the lower body.

[0053] Working principle: when the patient lies on the mattress 4 on the bed body 1, the part of the foot will be against one end of the bed body 1, which is in line with the position of the foot pedal 6. When the patient needs to pull up his spine and there is no accompanying person nearby, he needs to operate it by himself. The patient steps on the foot pedal 6 with his feet. The stepping of the two foot pedals 6 will be activated by the self-adjusting device, so that the self-adjusting device will start the spine lifting device. The activated spine lifting device drives the push rod 9 to lift the support seesaw 2. After the support seesaw 2 is tilted, the patient's spine is pulled;

[0054] When the patient needs to adjust the spinal traction part, he first steps on the foot pedal 6. After stepping on the foot pedal 6, the first rotating rod 23 and the second rotating rod 24 are driven to rotate. When the first rotating rod 23 is stepped on, the connecting component is driven to start, and the connecting component is rotated by the shaft sleeve 25 along with the rotation of the first rotating rod 23, and the rotation of the shaft sleeve 25 drives the movable sleeve 26 to rotate. After the movable sleeve 26 swings, the internal limiting column 31 moves in the limiting groove 30 along with the swing of the movable sleeve 26, and the rotation of the movable sleeve 26 drives the connecting plate 27 to swing. The connecting plate 27 and the second connecting plate 29 are fixed by the connecting shaft 28. Therefore, after the connecting plate 27 swings, it will rotate around the connecting shaft 28 as the center, so that the second connecting plate 29 at the other end can be adjusted. The second connecting plate 29 will also swing up and down with the rotation of the connecting plate 27. When the connecting assembly at one end is started, the connecting assembly at the other symmetrical end will also be started. After the footsteps on the pedal 6 at one end are stepped on, the footsteps on the pedal 6 at the other end will swing in the opposite direction due to the symmetry of the two groups. After the two groups of connecting assemblies are started, the two second connecting plates 29 will swing up and down, and the swing will drive the connecting plate 33 to move up and down, so that the swing rod 14 is started by the connecting plate 33. After the self-adjusting device is started, the spinal traction device will be started. The movement tracks of the two footsteps on the pedals 6 will form a walking movement, thereby exercising the legs and preventing the patient from lying in bed for a long time and causing muscle paralysis in the lower body.

[0055] When the self-adjusting device drives the spinal traction device to start, it will drive the swing rod 14 to swing up and down around the rotating shaft 12, and the swing rod 14 is connected to the rod sleeve 13. After the swing rod 14 swings, the rod sleeve 13 is rotated slightly, and there is a fixed block 17 on the rod sleeve 13, and there is a tooth hook 15 on the fixed block 17. After the clockwise rotation, the tooth hook 15 will be blocked by the blocking block 18 and will not rotate to the side. Therefore, after the clockwise rotation of the rod sleeve 13, it will drive the tooth hook 15 to rotate the gear 11. The gear hook 15 drives the gear 11 to rotate, and the gear 11 rotates, which drives the turntable 10 to rotate. The rotation of the turntable 10 drives the spiral block 21 on the back to rotate. The spacing of the spiral block 21 corresponds to the tooth groove 22 on the push rod 9. After the spiral block 21 rotates, the tooth groove 22 gradually rises along the spacing of the spiral block 21, so that the push rod 9 is gradually lifted up. The lifting of the push rod 9 makes the support rocker 2 tilt up, so that the mattress 4 forms an angle, so that the spine can be lifted up.

[0056] When it is necessary to put down the push rod 9, the adjusting rod 35 is moved to the side at the edge of the bed body 1 by the hand position, so that the adjusting rod 35 drives the moving seat 34 to move to the side, and the moving seat 34 drives the turntable 10 to move to the side. At this time, the turntable 10 drives the bracket sleeve 16 to move to the side, so that the slider 19 at the side end of the bracket sleeve 16 disengages from the original slide groove 20 and moves to the slide groove 20 on the other side. At this time, the spiral block 21 is also separated from the tooth groove 22. Without the support of the spiral block 21, the tooth groove 22 on the push rod 9 will also lose its supporting force, causing the push rod 9 to fall, and the mattress 4 returns to its original state.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
