DETAILED DESCRIPTION

[0027] The utility model is now described in further detail with reference to the accompanying drawings.

[0028] See also Figures 1 to 7The utility model provides a technical solution: a support frame, including a moving seat 1, a pillar 2, a lifting column 3, a support plate 4 and a side support plate 8. The upper end of the moving seat 1 is fixed with the pillar 2, and a movable cavity for installing the lifting column 3 is opened inside the pillar 2. The top of the lifting column 3 passes through the top of the pillar 2 and is fixed to the support plate 4 through an angle code. The upper end of the support plate 4 is fixed with a slide rail 6 for sliding two sliders 5. The upper ends of the two sliders 5 are threadedly connected with positioning bolts 7. The upper ends of the two sliders 5 are fixed with side support plates 8 for fixing the side parts of the patient's limbs. The upper ends of the two side support plates 8 are fixed with fixing rings 10 for installing Velcro straps 9. A protective pad 11 for increasing the comfort of the patient is provided between the two side support plates 8;

[0029] The rear ends of the two side support plates 8 are provided with reserved cavities for the ankle fixing plates 12 to be pulled out, and the two ankle fixing plates 12 are fixed by fixing bolts 13 threadedly connected to the outside of the reserved cavities, and the inner sides of the two ankle fixing plates 12 are provided with grooves for the ankles to be placed, and the opposite surfaces of the two ankle fixing plates 12 are bonded with silicone skin-friendly pads 14. Considering that in the current orthopedic clinical nursing activities, the elevation of the patient's limbs is basically supported by a support structure or a support structure to provide a fixed position, it is not only difficult to adjust the support height during use, but also the support interface is prone to shaking, and the position of the supported patient cannot be obtained. To overcome the drawbacks of fixation, the utility model can accurately adjust the support height of the patient's lower limbs supported by the support plate 4 through the lifting column 3 according to the lifting needs. The adjusted height will be detected by the infrared ranging sensor 26 to ensure that the device user accurately knows the lifting height, and in order to prevent the patient's lifted limbs from shaking left and right, two side support plates 8 will be used in conjunction with the inflatable airbag for fitting protection. At the same time, in order to prevent the patient's ankle from moving around after the calf is fixed, the ankle fixing plate 12 can be pulled out to fix the patient's ankle, which effectively prevents the patient's foot from tilting to the side, which can help The patient's foot is fixed in position. When in use, the driver 19 controls the rotation direction and number of rotations of the output shaft of the small motor 15. As the screw rod 17 rotates, the threaded sleeve 18 will drive the lifting column 3 to move. In this process, the lifting column 3 completes the longitudinal guidance through the wire rod, so that the lifting column 3 is lifted. When the lifting plate is lifted to the required lifting height of the patient's foot, it stops moving. At this time, the output shaft of the motor will complete the position locking through the self-locking structure of the small motor 15, and then the patient puts his legs on the slide rail 6 at the upper end of the support plate 4, and then slides the slider 5 so that the two side support plates 8 are slightly close to the sides of the patient's legs. The two inflatable airbags can be inflated through the air injection tube by a suction dual-purpose air pump, so that the protection pad 11 is fitted with the patient's legs. At this time, the fixing effect is optimal. When the patient's ankle position needs to be fixed, the fixing bolt 13 is loosened to allow the ankle fixing plate 12 to be pulled out. The pulling-out distance requires the groove to fit the protruding position of the patient's ankle. After the adjustment is completed, the fixing bolt 13 is tightened. Considering that the device needs to be easy to use, the device can be moved through the self-locking universal wheels when in use, and can be directly evacuated when not in use.

[0030] Among them, the interior of the pillar 2 is also provided with a placement cavity for installing a small motor 15 and a suction dual-purpose pump 16. The output shaft of the small motor 15 is fixedly connected to a screw rod 17 through a coupling. The upper end of the screw rod 17 passes through the active cavity and extends to the interior of the lifting column 3, and a threaded sleeve 18 is installed on the outside of the screw rod 17. The threaded sleeve 18 is fixedly installed inside the lifting column 3. A driver 19 is provided at the front end of the housing of the small motor 15. The driver 19 is provided to control the rotation direction and number of rotations of the output shaft of the small motor 15.

[0031] Among them, one end of the dual-purpose suction pump 16 passes through the back of the pillar 2 through a pipe, and the other end of the dual-purpose suction pump 16 is connected to a double-headed tube 20 through a pipe, and the two ports of the double-headed tube 20 are connected to the gas injection pipe. The dual-purpose suction pump 16 and the driver 19 are connected to the Bluetooth controller 21 circuit through a wire. The Bluetooth controller 21 is used to receive the control signal of the external controller 22. The external controller 22 is set on one side of the pillar 2. Considering the situation that the patient needs to get out of bed and move around, the device can use external control to cooperate with the Bluetooth controller 21 to remotely control the descent of the pallet 4 and the suction of the gas inside the inflatable airbag, so that the patient can get out of bed and move around alone. The external controller 22 is connected to the Bluetooth controller 21 through Bluetooth technology. After the connection is completed, the external controller 22 releases the control signal through the Bluetooth module. At this time, the Bluetooth module inside the Bluetooth controller 21 will receive the control signal and perform signal control on the driver 19 and the dual-purpose suction pump 16.

[0032] Among them, the opposite surfaces of the two side branch plates 8 are fixed to the inflatable airbag cushion 24 through the first Velcro 23, and the opposite surfaces of the two inflatable airbag cushions 24 are fixed to the protection pad 11 through the second Velcro 25. The first Velcro 23 and the second Velcro 25 both include a Velcro hook surface and a Velcro fleece surface. The air nozzle of the inflatable airbag cushion 24 is connected to the air injection tube. By setting the gap between the inflatable airbag cushion 24 and the patient's fixed limb and the two side branch plates 8, a compensation effect is played. The protection pad 11 can be driven to contact the surface of the patient's limb through the expansion of the inflatable airbag cushion 24.

[0033] Among them, a groove for installing the infrared ranging sensor 26 is opened on one side of the bottom of the lifting column 3, and the infrared ranging sensor 26 is connected to the circuit of the Bluetooth controller 21 through a wire. By setting the infrared ranging sensor 26, the user can know the rising or falling height of the lifting column 3, and the rising or falling height of the lifting column 3 is equal to the rising height or falling height of the support plate 4 supporting the patient's limbs, which is convenient for the user to lift the patient's limbs to the required height and help blood circulation.

[0034] Among them, rotatable balls 27 are provided on both sides of the bottom end of the lifting column 3, and the outer wall of the ball 27 is in contact with the inner wall of the movable cavity. Guide holes for installing guide rods are penetrated on both sides of the bottom end of the lifting column 3. The arrangement of the ball 27 plays a smooth role between the lifting column 3 and the movable cavity, so that when the lifting column 3 is lifted or lowered inside the movable cavity, the ball 27 contacts and slides with the inner wall of the movable cavity.

[0035] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
