Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a support device for neurological examinations. Background Technology

[0002] Currently in neurology clinics, medical staff need to examine the affected areas of patients with localized nerve atrophy or insensitivity to localized nerve stimulation. During the examination, sometimes it is necessary for the patient to raise their upper or lower limbs. However, most patients have limited limb movement and cannot move freely, requiring assistance from medical staff. This makes both medical staff and patients feel very tired and inconvenient for the examination. Therefore, there is a need to design a support device for neurological examinations.

[0003] Chinese patent document CN210078193U discloses a neurological examination support device, including a bed. The device is characterized by: two fixing blocks fixed to both ends of one side of the bed board; two fixing blocks threadedly connected to screw rods; the upper ends of the two screw rods hinged to the lower ends of a straight groove rod; symmetrical sliders are embedded within the straight groove rod; and screw rods are hinged to the grooves of the straight groove rods; the screw rods are connected to the sliders via two reverse threads. This utility model relates to the field of examination support equipment, specifically a neurological examination support device. This device can assist medical personnel in supporting the patient's limbs.

[0004] The existing technology has the following problems:

[0005] The device uses two screws and a pair of straight groove rods to adjust the height, and a belt to synchronize the two screws. However, in actual operation, because the belt drives the wheel to rotate by friction, and the screw drive is a relatively precise transmission method, it is difficult for the two screws to rotate synchronously in the initial stage of rotation. This may cause the parts to be squeezed and damaged. At the same time, compared with the adjustment of the distance between the two support plates, the adjustment of the height of the straight groove rod is more frequent. This may cause the parts to wear due to frequent gripping of the parts when using screw-driven lifting. Utility Model Content

[0006] This invention provides a support device for neurological examinations to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A neurological examination support device includes a support frame.

[0009] The lifting mechanism includes a movable seat, the outer side of which is slidably connected to the inner side of the upper wall of the support frame, and two movable seats are symmetrically distributed on the left and right. The bottom of each of the two movable seats is rotatably connected to a fixed pulley. The upper side of each of the two movable seats is fixedly connected to a first motor near the fixed mechanism. The output end of each of the two first motors is fixedly connected to a winding disc. The inner side of each of the two winding discs is wound with a first traction rope. The lower side of the first traction rope overlaps the inner side of the fixed pulley. The upper side of the fixed mechanism is fixedly connected to the lower end of the first traction rope.

[0010] Preferably, a second motor is fixedly connected to the right side of the support frame near the upper side, and a screw is fixedly connected to the output end of the second motor. The outer side of the screw is rotatably connected to the inner side of the upper wall of the support frame near the left and right sides, and the inner side of the movable seat is threadedly connected to the outer side of the screw.

[0011] Preferably, the fixing mechanism includes a base plate, the upper side of which is fixedly connected to the lower side of the first traction rope, and the lower side of the base plate is rotatably connected to a rotating plate via a hanging rod. A mechanism plate is slidably connected to the inner side of the lower boss of the rotating plate, and a strap is fixedly connected to the lower side of the mechanism plate.

[0012] Preferably, a limiting block is movably sleeved on the inner side of the rotating plate near the front side, the rear side of the limiting block is in contact with the front side of the mechanism plate, and a spring is movably sleeved on the inner side of the rotating plate near the front side, with the spring located above the limiting block.

[0013] Preferably, a third motor is fixedly connected to the lower side of the substrate away from the first motor. The output end of the third motor is fixedly connected to a second winding disc. The left and right sides of the second winding disc are rotatably connected to the lower side of the substrate, and two second winding discs are symmetrically distributed front and back. A second traction rope is wound and connected to the inner side of each of the two second winding discs. The lower end of the second traction rope is fixedly connected to the upper side of the rotating plate near the front and back sides. Gears are fixedly connected to the shaft of each of the two third motors on the side closest to the first motor.

[0014] Preferably, two limiting rods symmetrically distributed front and rear are movably sleeved on the upper side of the substrate near the front and rear sides, and the outer side of the limiting rods near the upper side is movably sleeved on the inner side of the horizontal plates on the front and rear sides of the movable seat.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1.

The first motor drives the winding disc to rotate, which causes the first traction rope to pull the fixing mechanism up and down. The third motor drives the second winding disc to rotate, which causes the rotating plate to tilt to adapt to the direction of the patient's limb, thereby achieving the purpose of lifting the patient's limb. The use of a first traction rope and a second traction rope avoids the problem of excessive wear of components caused by the frequent rotation of the threaded rod when using a threaded rod for lifting.

By rotating the rotating sleeve, the movement of the ball bearing is controlled, thereby adjusting the height of the limiting rod relative to the base plate. This ensures that the device does not have any protruding parts when stored, making it easy to store and allowing for quick reset without affecting its use. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a neurological examination support device includes a support frame 1. Two movable platforms 2 are fixedly connected to the lower side of the support frame 1 near the left and right sides. Two control levers 3 are movably installed in the middle of the left and right sides of the support frame 1. A lifting mechanism 4 is rotatably connected to the inner side of the upper wall of the support frame 1. Two fixing mechanisms 5 are fixedly connected to the lower side of the lifting mechanism 4.

[0028] The lifting mechanism 4 includes a movable seat 41, the outer side of which is slidably connected to the inner side of the upper wall of the support frame 1. Two movable seats 41 are symmetrically distributed on the left and right sides. The bottom of each movable seat 41 is rotatably connected to a fixed pulley 42. The upper side of each of the two movable platforms 2 is fixedly connected to a first motor 43 near the fixed mechanism 5. The output end of each of the two first motors 43 is fixedly connected to a winding disc 44. The inner side of each of the two winding discs 44 is wound with a first traction rope 45. The lower side of the first traction rope 45 overlaps the inner side of the fixed pulley 42. The upper side of the fixed mechanism 5 is fixedly connected to the lower end of the first traction rope 45.

[0029] It should be noted that the first motor 43 drives the winding disc 44 to rotate. When the winding disc 44 rotates, the first traction rope 45 is wound or extended on the winding disc 44. The first traction rope 45 is turned by the fixed pulley 42, so that the first traction rope 45 drives the fixed mechanism 5 to move up and down. One of the control levers 3 is used to control the first motor 43. When the control lever 3 rotates clockwise, the fixed mechanism 5 rises, and when the control lever 3 rotates counterclockwise, the fixed mechanism 5 falls.

[0030] like Figure 3As shown, a second motor 46 is fixedly connected to the right side of the support frame 1 near the upper side. A screw 47 is fixedly connected to the output end of the second motor 46. The outer side of the screw 47 is rotatably connected to the inner side of the upper wall of the support frame 1 near the left and right sides. The inner side of the movable seat 41 is threadedly connected to the outer side of the screw 47.

[0031] It should be noted that the second motor 46 drives the screw 47 to rotate. The screw 47 is a bidirectional screw, which causes the two moving seats 41 to move closer or further apart when the screw 47 rotates, thereby adjusting the distance between the two fixed mechanisms 5.

[0032] like Figure 4 , Figure 5 As shown, the fixing mechanism 5 includes a base plate 51. The upper side of the base plate 51 is fixedly connected to the lower side of the first traction rope 45. The lower side of the base plate 51 is rotatably connected to a rotating plate 52 via a hanging rod. The inner side of the lower boss of the rotating plate 52 is slidably connected to a mechanism plate 53. The lower side of the mechanism plate 53 is fixedly connected to a strap 54.

[0033] It should be noted that the strap 54 is used to fix the patient's limbs, and the strap 54 can be fixed to the outside of the patient's limbs using Velcro or quick-release buckles.

[0034] like Figure 5 As shown, a limiting block 55 is movably sleeved on the inner side of the rotating plate 52 near the front side. The rear side of the limiting block 55 is in contact with the front side of the mechanism plate 53. A spring 56 is movably sleeved on the inner side of the rotating plate 52 near the front side, and the spring 56 is located above the limiting block 55.

[0035] It should be noted that the limiting block 55 is used to limit the mechanism plate 53. Pushing the limiting block 55 upwards allows the mechanism plate 53 to be removed from the rotating plate 52, thereby quickly removing the strap 54 from the rotating plate 52. This avoids the need for disinfection and maintenance of the strap 54 after using the device on patients with skin diseases. At the same time, the strap 54 can be quickly installed on the rotating plate 52.

[0036] like Figure 4 As shown, a third motor 57 is fixedly connected to the lower side of the substrate 51 away from the first motor 43. The output end of the third motor 57 is fixedly connected to a second winding disc 58. The left and right sides of the second winding disc 58 are rotatably connected to the lower side of the substrate 51, and two second winding discs 58 are symmetrically distributed front and back. The inner sides of the two second winding discs 58 are wound with second traction ropes 511. The lower ends of the second traction ropes 511 are fixedly connected to the upper side of the rotating plate 52 near the front and back sides. Gears 510 are fixedly connected to the shaft of the two third motors 57 on the side near the first motor 43.

[0037] It should be noted that the third motor 57 drives the second winding disc 58 to rotate. When the second winding disc 58 rotates, the second traction rope 511 is wound or extended on the second winding disc 58. The two gears 510 mesh with each other and are connected together, causing the two second winding discs 58 to rotate synchronously in opposite directions. This causes the second traction rope 511 to drive the rotating plate 52 to rotate on the lower side of the base plate 51, thereby adapting to the direction of the patient's limb and making the patient more comfortable. One of the control levers 3 is used to control the third motor 57, so that when the control lever 3 rotates clockwise, the rotating plate 52 rotates clockwise, and when the control lever 3 rotates counterclockwise, the rotating plate 52 rotates counterclockwise.

[0038] like Figure 4 As shown, two limiting rods 512 are movably sleeved on the upper side of the substrate 51 near the front and rear sides. The outer side of the limiting rods 512 is movably sleeved on the inner side of the horizontal plates on the front and rear sides of the movable seat 41 near the upper side.

[0039] It should be noted that the limiting rod 512 is used to limit the substrate 51, so that the substrate 51 can only move up and down, and cannot move to the four sides.

[0040] like Figure 6 As shown, two limiting components 59 are fixedly connected to the front and rear sides of the upper side of the substrate 51. The limiting components 59 include a fixed sleeve 591. The lower side of the fixed sleeve 591 is fixedly connected to the upper side of the substrate 51 near the front and rear sides. A rotating sleeve 592 is rotatably connected to the outer side of the fixed sleeve 591. Several annularly distributed balls 593 are movably sleeved on the inner side of the side wall of the fixed sleeve 591. Several annularly distributed disengagement grooves 594 are opened on the inner side of the rotating sleeve 592.

[0041] It should be noted that a torsion spring is provided between the rotating sleeve 592 and the fixed sleeve 591 to stabilize the state of the rotating sleeve 592. In the initial state, the dislocation groove 594 is misaligned with the ball 593, and the outer side of the ball 593 is movably sleeved in the ball groove near the upper and lower sides of the outer side of the limiting rod 512. Due to the restriction of the rotating sleeve 592, the ball 593 is fixed, thereby fixing the limiting rod 512 and the limiting component 59. Rotating the rotating sleeve 592 aligns the dislocation groove 594 with the ball 593, thereby allowing the ball 593 to move. The limiting rod 512 can move up and down with the limiting component 59. When the device is in use, the ball 593 is movably sleeved into the ball groove near the lower side of the limiting rod 512. When the device is in storage, the ball 593 is movably sleeved into the ball groove near the upper side of the limiting rod 512.

[0042] The working principle of this utility model is as follows: First, the first motor 43 drives the winding disc 44 to rotate. When the winding disc 44 rotates, the first traction rope 45 is wound or extended on the winding disc 44. Relying on the fixed pulley 42 to steer the first traction rope 45, the first traction rope 45 drives the fixed mechanism 5 to move up and down. One of the operating levers 3 is used to control the first motor 43. When the operating lever 3 rotates clockwise, the fixed mechanism 5 rises; when the operating lever 3 rotates counterclockwise, the fixed mechanism 5 falls. The third motor 57 drives the second winding disc 58 to rotate. When the second winding disc 58 rotates, the second traction rope 511 is wound or extended on the second winding disc 58. The two gears 510 mesh with each other. When connected, the two second winding discs 58 rotate synchronously in opposite directions, causing the second traction rope 511 to drive the rotating plate 52 to rotate on the lower side of the base plate 51, thereby adapting to the direction of the patient's limb and making the patient more comfortable. One of the control levers 3 is used to control the third motor 57, so that when the control lever 3 rotates clockwise, the rotating plate 52 rotates clockwise, and when the control lever 3 rotates counterclockwise, the rotating plate 52 rotates counterclockwise. The first motor 43 drives the winding disc 44 to rotate, causing the first traction rope 45 to pull the fixing mechanism 5 to move up and down. The third motor 57 drives the second winding disc 58 to rotate, causing the rotating plate 52 to tilt to adapt to the direction of the patient's limb, thereby achieving the desired effect on the patient's limb. To facilitate limb support, a first traction rope 45 and a second traction rope 511 are used to avoid the problem of excessive wear caused by frequent rotation of the threaded rod in lifting and lowering. Finally, a torsion spring is provided between the rotating sleeve 592 and the fixed sleeve 591 to stabilize the state of the rotating sleeve 592. In the initial state, the dislocation groove 594 is misaligned with the ball 593, and the outer side of the ball 593 is movably sleeved in the ball groove near the upper and lower sides of the outer side of the limiting rod 512. Due to the restriction of the rotating sleeve 592, the ball 593 is fixed, thereby fixing the limiting rod 512 and the limiting component 59. Rotating the rotating sleeve 592 aligns the dislocation groove 594 with the ball. 593, which allows the ball 593 to move, and the limiting rod 512 to move up and down with the limiting component 59. When the device is in use, the ball 593 is movably sleeved into the ball groove near the lower side of the limiting rod 512. When the device is in storage, the ball 593 is movably sleeved into the ball groove near the upper side of the limiting rod 512. By rotating the rotating sleeve 592, the movement of the ball 593 can be controlled, so that the height of the limiting rod 512 relative to the base plate 51 is adjusted. This ensures that there are no protruding parts in the storage state, making the device easy to store and allowing it to be quickly reset without affecting its use.
