Description

[Technical Field]

[0001] This invention relates to the technical field of medical devices, and in particular to the technical field of portable limb elevation devices. [Background Technology]

[0002] For surgical or non-surgical patients with limb injuries, fractures, soft tissue injuries, or those who are bedridden for extended periods, it is necessary to keep the distal end of the affected limb higher than the proximal end when the affected limb is at rest. This allows blood and lymph to flow back to the heart more quickly under the influence of gravity, thereby reducing or preventing limb edema and preventing problems such as delayed wound healing or even skin flap necrosis. Ultimately, this achieves the effects of prevention, treatment, rehabilitation, and relief of patient suffering.

[0003] Currently, in clinical practice, elevation pads are commonly used to elevate the affected limb and create a height difference, such as the orthopedic modified lower limb elevation pad disclosed in utility model patent CN215607116U. However, these elevation pads are usually difficult to adjust in height, and the required limb elevation height may vary for patients with injuries to different parts of the limb. Furthermore, limb exudate may not only contaminate the outer surface of the elevation pad but also seep into the pad body, making it difficult to clean and disinfect, potentially leading to wound infection in the patient or cross-infection between different patients. To address this, invention patent CN114452112A discloses an upper limb elevation pad for fracture patients that utilizes a hydraulic cylinder or pneumatic cylinder to elevate both the first and second elevation pads, thus meeting the limb elevation needs of different patients. However, hydraulic cylinders or pneumatic cylinders require corresponding oil or air supply mechanisms, resulting in a larger device size and exposed oil sleeves or air pipes. Furthermore, both of the aforementioned existing technologies can only support the affected limb from the bottom, without any restraint on the top of the affected limb, which makes it easy for the patient to inadvertently remove the affected limb, thus causing the affected limb to no longer be kept at the designated height. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a portable limb angle elevation device that can stably wrap and fix the affected limb and raise it to a specified height as needed. The overall structure is simple, occupies little space, has no electronic components, is inexpensive, easy to maintain, and highly portable. At the same time, the padding is easy to clean and disinfect.

[0005] To achieve the above objectives, the present invention proposes a portable limb rated angle elevation device, comprising a telescopic rod, a pad, suspension ropes, and rope seats. Two rope seats are arranged opposite each other on the left and right sides and their heights are adjusted by the telescopic rod. The pad is located between the two rope seats and has several suspension ropes on both sides. The other end of a suspension rope fixed to the left side of the pad is detachably connected to a rope seat located on the right side of the pad, and the other end of a suspension rope fixed to the right side of the pad is detachably connected to a rope seat located on the left side of the pad. The left and right sides of the pad are forced together by the intersecting suspension ropes to form a roll.

[0006] Preferably, the rope seat is provided with a rope channel through which the suspension rope can pass. The inner wall of the rope channel is provided with a number of recesses. The inner wall of the rope channel is also provided with a number of internally threaded holes that are arranged opposite to each of the recesses and extend outward through the rope seat. Each of the internally threaded holes is threaded with a positioning bolt. The bottom end of each positioning bolt squeezes a section of the suspension rope into the corresponding recess.

[0007] Preferably, the telescopic rod includes a support plate, a rod sleeve, a rod body, and a drive locking mechanism. The rod sleeve is vertically fixed to the top surface of the support plate, and the bottom end of the rod body is inserted downward into the sleeve channel of the rod sleeve and is driven to move up and down by the drive locking mechanism to fix its position.

[0008] Preferably, the outer wall of the rod body is provided with a number of teeth arranged sequentially from top to bottom, and the rod sleeve is provided with a notch that exposes a section of the teeth of the rod body. The drive locking mechanism includes a movable frame, a wheel, and a dropper. One side of the wheel is provided with a spindle and a spiral protrusion. The other end of the spindle is rotatably connected to the movable frame. The spiral protrusion is coiled around the periphery of the spindle. The dropper is fixed on the movable frame and is arranged opposite to the wheel. The movable frame is sleeved outside the rod sleeve and the side with the wheel is hinged to the rod sleeve. In its natural state, the top of the wheel extends into the notch under the gravity of the dropper, and the spiral protrusion engages with the teeth.

[0009] Preferably, the drive locking mechanism further includes a handle, which is fixed to the side of the wheel opposite to the notch.

[0010] Preferably, the drop body is cylindrical and eccentrically hinged to the movable frame.

[0011] Preferably, the drive locking mechanism further includes a pull rod, one end of which is connected to the drop body.

[0012] Preferably, the drive locking mechanism further includes a retainer, which is fixed to the outer wall of the rod sleeve and located below the drop body. The retainer is provided with a groove that can engage with the pull rod.

[0013] The beneficial effects of this invention are:

[0014] 1) By setting two telescopic rods to adjust the height of the two rope seats respectively, and then using several cross-set suspension ropes to roll the pad into a roll shape and place it between the left and right rope seats, it can stably wrap and fix the affected limb and raise the affected limb to the specified height as needed. The overall structure is simple, occupies a small area, has no electronic parts, is inexpensive, easy to maintain, and has good portability. At the same time, the pad is easy to clean and disinfect.

[0015] 2) By setting a rope channel on the rope seat for the hoisting rope to pass through, and setting several sets of oppositely arranged concave parts and internal threaded holes on the inner wall of the rope channel, the positioning bolts that are threaded into each internal threaded hole can be used to squeeze multiple sections of the hoisting rope into each concave part, thereby achieving fast and stable fixation of the hoisting rope.

[0016] 3) The drive and locking mechanism is formed by setting up a movable frame, a wheel, and a drop body. At the same time, the top of the wheel extends into the notch under the gravity of the drop body in a natural state, and the spiral protrusions and teeth mesh together. When the wheel rotates in the forward or reverse direction, the interaction between the spiral protrusions and teeth drives the rod to move up or down along the sleeve channel of the rod sleeve. When the wheel stops rotating, the rod can also remain in the original position. When the top of the wheel extends out of the notch, the rod can also quickly descend to the bottom, thereby greatly improving the convenience of adjusting the height of the rope seat.

[0017] 4) By making the drop body columnar and eccentrically hinged to the movable frame, a tie rod is added on the drop body, and a locking seat is installed on the outer wall of the rod sleeve. The locking between the tie rod and the locking seat can prevent the wheel from accidentally leaving the notch during use, thereby effectively preventing the pole from falling down unexpectedly.

[0018] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0027] See Figures 1 to 7 The present invention relates to a portable limb elevation device with a rated angle, comprising a telescopic rod 1, a pad 2, suspension ropes 3, and rope seats 5. Two rope seats 5 are arranged opposite each other on the left and right sides and their heights are adjusted by the telescopic rod 1. The pad 2 is located between the two rope seats 5 and has several suspension ropes 3 on its left and right sides respectively. The other end of a suspension rope 3 fixed to the left side of the pad 2 is detachably connected to a rope seat 5 located on the right side of the pad 2, and the other end of a suspension rope 3 fixed to the right side of the pad 2 is detachably connected to a rope seat 5 located on the left side of the pad 2. The left and right sides of the pad 2 are forced together by the cross-arranged suspension ropes 3 to form a cloth roll.

[0028] The rope seat 5 is provided with a rope channel 51 through which the suspension rope 3 can pass. The inner wall of the rope channel 51 is provided with a number of recesses 52. The inner wall of the rope channel 51 is also provided with a number of internal threaded holes 53 that are arranged one-to-one with each recess 52 and extend outward through the rope seat 5. Each internal threaded hole 53 is threaded with a positioning bolt 4. The bottom end of each positioning bolt 4 squeezes a section of the suspension rope 3 into the corresponding recess 52.

[0029] The telescopic rod 1 includes a support plate 11, a rod sleeve 12, a rod body 13, and a drive locking mechanism 14. The rod sleeve 12 is vertically fixed to the top surface of the support plate 11. The bottom end of the rod body 13 is inserted downward into the sleeve channel of the rod sleeve 12 and is driven up and down by the drive locking mechanism 14 to fix its position.

[0030] The outer wall of the rod 13 is provided with a plurality of teeth 131 arranged sequentially from top to bottom. The rod sleeve 12 is provided with a notch 121 that exposes a section of the teeth 131 of the rod 13. The drive locking mechanism 14 includes a movable frame 141, a wheel 142 and a drop body 143. One side of the wheel 142 is provided with a spindle 1421 and a spiral protrusion 1422. The other end of the spindle 1421 is rotatably connected to the movable frame 141. The spiral protrusion 1422 is coiled around the periphery of the spindle 1421. The drop body 143 is fixed on the movable frame 141 and is arranged opposite to the wheel 142. The movable frame 141 is sleeved outside the rod sleeve 12 and is hinged to the rod sleeve 12 on the side with the wheel 142. In a natural state, the top of the wheel 142 extends into the notch 121 under the gravity of the drop body 143 and the spiral protrusion 1422 engages with the teeth 131.

[0031] The drive locking mechanism 14 also includes a handle 144, which is fixed to the side of the wheel 142 opposite to the notch 121.

[0032] The drop body 143 is columnar and is eccentrically hinged to the movable frame 141.

[0033] The drive locking mechanism 14 also includes a pull rod 145, one end of which is connected to the drop body 143.

[0034] The drive locking mechanism 14 also includes a card seat 146, which is fixed to the outer wall of the sleeve 12 and located below the drop body 143. The card seat 146 is provided with a slot that can engage with the pull rod 145.

[0035] The working process of this invention:

[0036] First, place the affected limb on the pad 2. Pass the free ends of the slings 3 on the right side of the pad 2 through the rope channels 51 of the rope seat 5 on the left side of the pad 2. Then pull the crossed slings 3 until the pad 2 is rolled up and wraps around the affected limb. Next, tighten the positioning bolts 4 until the bottom of each bolt pushes a section of the sling 3 into its corresponding recess 52, thus securing the slings 3. Then, as... Figure 3 and Figure 4 As shown, the handle 144 drives the wheel 142 to rotate, and the interaction between the spiral protrusion 1422 and the teeth 131 moves the rod 13 and the rope seat 5 mounted on it up and down along the sleeve channel until the affected limb wrapped in the cloth roll is at the required height. (See reference...) Figure 5 and Figure 6If it is necessary to quickly lower the affected limb, first pull the lever 145 out of the holder 146, rotate the drop 143 until it is no longer pressed against the outer wall of the lever sleeve 12, and then push the movable frame 141 so that the top of the wheel 142 extends out of the notch 121. At this time, since the spiral protrusion 1422 and the teeth 131 are no longer engaged, the lever 13 can fall freely to the lowest point.

[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
