Description

Technical Field

[0001] This utility model relates to the field of medical assistive devices, and in particular to an adjustable inflatable limb elevator. Background Technology

[0002] In clinical practice, lower limb skeletal traction is a common method for treating lower limb fractures. Common methods include femoral-ankle traction, tibial tuberosity traction, and calcaneal traction. However, due to the generally long traction time, patients need to remain in bed for extended periods, and the traction limb is immobilized, which can easily lead to complications such as pressure sores, traction pin slippage, pin site infection, and foot drop. This necessitates the use of traction devices to elevate the lower limb and address lower limb fractures. However, during clinical treatment, the traction and immobilization, resulting in prolonged fixed positions, can cause discomfort for patients, making skin cleaning difficult. Prolonged pressure on bony prominences and the heel can easily lead to pressure sores, and prolonged immobilization or lack of effective exercise due to pain can cause foot drop. Therefore, we have designed an adjustable inflatable limb elevation frame that can be adjusted to a comfortable level based on patient experience, suitable for different patients; it allows for breathability of the skin under pressure to prevent pressure sores; it maintains the functional position of the traction limb to prevent foot drop; and when not in use, it can be folded for storage, saving space.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please see Figures 1 to 6 This utility model provides an embodiment:

[0022] Please see Figure 1 and Figure 3 An adjustable inflatable limb lifter includes a retractable foldable support frame 1 and an inflatable pad 2 disposed on the retractable foldable support frame 1. A guide frame is provided on one side of the retractable foldable support frame 1, and a guide wheel 8 is provided on the top of the retractable foldable support frame 1.

[0023] Please see Figure 3 and Figure 4 The retractable and foldable support frame includes a base frame 101 and a support frame 102. Each of the four corners of the base frame 101 is hinged to the corresponding four corners of the support frame 102 via a vertical rod 103. When folding is required, the angle of the vertical rod 103 is adjusted, and the support frame 102 can be folded accordingly.

[0024] Please see Figure 1 and Figure 3 The vertical rods 103 of the telescopic and foldable support frame 1 are all telescopic support rods.

[0025] Please see Figure 1 , Figure 3 and Figure 6 The guide frame includes a first guide rod 4 and a second guide rod 5. One end of both the first guide rod 4 and the second guide rod 5 is hinged to one side of the telescopic and foldable support frame 1. Both the first guide rod 4 and the second guide rod 5 are provided with adjusting rods 6 to adjust their horizontal angles. The adjusting rod 6 consists of two telescopic adjusting rods of different thicknesses. Each section of the adjusting rod 6 has several corresponding bolt holes for bolt insertion. The horizontal angle of the first guide rod 4 and the second guide rod 5 is adjusted by adjusting the position of the bolts in different bolt holes, and finally, the rods are locked with nuts.

[0026] Please see Figure 1 and Figure 3 The retractable and foldable support frame 1 is provided with anti-slip rollers 13 below. The rollers 13 have two roller blocks 14. When the rollers 13 do not need to move, the two roller blocks 14 are pressed down to the front and rear positions of the rollers 13 respectively to lock the rollers 13 and prevent them from sliding.

[0027] Please see Figure 3 and Figure 4The guide wheel 8 is mounted on the support arch 10, which is hinged to the telescopic foldable support frame 1. The support arch 10 is fastened to the support frame 102 of the telescopic foldable support frame 1, and its angle can be adjusted as needed before being fixed with bolts. A first support rod 7 is mounted on the vertical rod 103 of the telescopic foldable support frame 1, and a limit block is provided on the first support rod 7. A second support rod 9 is provided on the support arch 10, and the second support rod 9 is limited by inserting into the limit block on the first support rod 7, so that the support arch 10 is fixed when it reaches the maximum tilt angle.

[0028] Please see Figure 1 and Figure 2 The inflatable pad has fixing ropes 15 on both sides for binding to the retractable and foldable support frame 1.

[0029] Working principle: The retractable foldable support frame 1 moves to a suitable position via the rollers 13 located below it.
