Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a leg dressing support device and its usage method for trauma orthopedics. Background Technology

[0002] In trauma orthopedic clinical nursing, leg dressing changes are an extremely frequent procedure. For patients with lower limb fractures, soft tissue injuries, or postoperative conditions, dressing changes require elevating the affected leg and exposing the wound to facilitate debridement, disinfection, and dressing replacement by medical staff. Traditional dressing changes often involve using pillows, blankets, or other items to elevate the affected limb, or the patient supporting it themselves with assistance from family members. These methods suffer from instability in height, narrow support surface, and insufficient support, easily causing patient discomfort, limb slippage, or even secondary injury. Studies have shown that adjustable lower limb rehabilitation braces are significantly superior to ordinary pillows and Thomas braces in terms of suitable limb elevation height and stability, with a lower complication rate, effectively improving patient comfort and reducing complications.

[0003] Therefore, various devices for leg dressing support have been proposed in recent years. For example, CN223746634U discloses an orthopedic dressing device, including a collection container, a lifting rod, a guide rod, and a leg support plate. The device uses a flow guiding component to direct the medication into a basin, reducing splashing and preventing environmental pollution. However, the leg support plate of this device is a single-plate structure, making it impossible to adjust the spacing between the two support plates. This makes it difficult to fully expose the patient's leg wound, affecting the ease of operation for medical staff. CN223158546U discloses a leg support for lower limb dressing, which achieves height adjustment through the pull-pull mechanism of upper and lower support steel pipes and is fixed to the side of the bed by clamps. Although this device has height adjustment capabilities, its support part is only a single-point footrest, resulting in insufficient stability after the patient's leg is placed. Furthermore, it lacks an effective restraint structure, and during dressing changes, the patient may experience leg tremors due to pain, causing the support to shake and potentially leading to secondary injuries, posing a safety hazard. CN222304246U discloses an orthopedic dressing change bracket that uses a limiting plate driven by a threaded rod to fix the patient's lower limb. However, the fixation method is to press down from top to bottom, which is relatively cumbersome to operate, and the pressing force is applied directly to the affected limb, which may cause discomfort.

[0004] Furthermore, existing dressing change supports generally suffer from design redundancy in their adjustable functions. For example, CN224085611U discloses a leg support device for orthopedic nursing, which uses a rotating rod and a complex transmission structure to adjust the angle of the support plate. Adjustment is achieved through a series of transmissions via a hand-held pressing rod. This complex transmission mechanism increases the manufacturing cost and maintenance difficulty of the device, and actually reduces its efficiency in clinical practice. CN121796169A discloses an orthopedic leg dressing change support frame that uses an electric push rod as the lifting mechanism. Although it achieves electric adjustment, its cost is high, and the electric device poses electrical safety hazards and failure risks in humid dressing change environments.

[0005] In summary, existing dressing support devices generally suffer from the following technical defects: (1) Insufficient fixation of the patient's legs, resulting in the inability to effectively restrain lower limb tremors caused by pain during dressing changes, posing a risk of secondary injury; (2) Height adjustment methods mostly employ electric devices or complex transmission mechanisms, which are cumbersome to operate, pose risks, and are costly; (3) Lack of spacing adjustment design for wound exposure, simple support plate structure, and limited operating space during dressing changes; (4) Poor compatibility between multiple structures, resulting in a complex and redundant overall device, high manufacturing costs, and difficulty in clinical promotion. Therefore, there is an urgent need for a dressing support device that is structurally simple, functionally reliable, easy to operate, and can simultaneously meet the needs of leg fixation and wound exposure. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a leg dressing support device and its usage method for trauma orthopedics, solving the technical problems of existing dressing support devices being unable to effectively restrain the patient's lower limbs, having cumbersome height adjustment operations, and having limited space for dressing changes.

[0007] A leg dressing support device for trauma orthopedics and its usage method, comprising: a base, a lifting assembly, and a bracket assembly. The lower end of the lifting assembly is fixedly connected to the base, and the upper end of the lifting assembly is connected to the bracket assembly. The lifting assembly is configured to adjust the height of the bracket assembly relative to the base. The bracket assembly includes a fixed bracket and a sliding bracket. The fixed bracket is fixedly installed on the upper end of the lifting assembly. A groove is provided on the base, and the sliding bracket is slidably connected to the groove. Both the fixed and sliding brackets have horizontally penetrating arc-shaped grooves on their upper surfaces, and these grooves are aligned, forming a dressing gap between the two brackets. A strap assembly is fixedly installed on the side of the fixed bracket. The strap assembly includes a fixed plate on the side of the fixed bracket, a sliding groove within the fixed plate, a sliding block that limits sliding within the sliding groove, and a strap fixedly connected to the sliding block.

[0008] Preferably, the lifting assembly includes a sleeve, a lifting rod, and a locking knob; the lower end of the sleeve is fixedly connected to the base, the lower end of the lifting rod is retractably inserted into the sleeve, and the upper end of the lifting rod is fixedly connected to a fixed support plate; the locking knob is threaded onto the side wall of the sleeve and is used to lock the retracted position of the lifting rod relative to the sleeve. This structure avoids complex electric or transmission mechanisms, and height locking can be achieved simply by extending and retracting the sleeve in conjunction with the locking knob. The operation is intuitive and reliable, and it is suitable for rapid clinical adjustment.

[0009] Preferably, the base is equipped with multiple casters at the bottom, and the casters have a locking mechanism.

[0010] Preferably, it also includes a waste liquid collection component, which includes a bracket and a collection tank. The bracket is fixedly installed on the lifting rod, and the collection tank is detachably hung on the bracket. The opening of the collection tank is located directly below the dressing change gap between the fixed tray and the sliding tray.

[0011] Preferably, a shelf is fixedly installed on the side of the lifting rod.

[0012] Preferably, the fixed tray and the sliding tray are provided with removable elastic pads in their arc-shaped grooves.

[0013] Preferably, a slider is fixedly provided at the bottom of the sliding plate, and the slider slides in the groove; the bottom of the groove is provided with a plurality of positioning holes arranged at intervals along the extension direction of the groove, and a spring positioning pin is provided on the slider, which selectively engages with the positioning hole.

[0014] Preferably, the strap is an elastic strap, and the free end of the strap is provided with Velcro.

[0015] Furthermore, the present invention also provides a method of using a leg dressing support device for trauma orthopedics, employing the leg dressing support device for trauma orthopedics as described above, including the following steps: S1: Place the device at the foot of the bed and lock the casters to fix the base. S2: Based on the patient's leg length, slide the sliding support plate along the groove and adjust the distance between the fixed support plate and the sliding support plate so that the patient's leg can be supported by the arc groove on both the fixed support plate and the sliding support plate at the same time. S3: Adjust the height of the support assembly according to the patient's position and wound location using the lifting assembly, so that the patient's leg wound is exposed in the dressing change gap between the fixed support plate and the sliding support plate. S4: Place the patient's leg on the arc groove, and adjust the binding position of the strap to avoid the wound according to the location of the leg wound by moving the sliding block along the sliding groove. Then use the strap to fix the patient's leg to the bracket assembly. S5: Hang the collection bucket on the rack, aligning the opening of the collection bucket directly below the dressing change interval, and begin the dressing change operation. S6: After changing the dressing, loosen the bandage, release the fixation on the patient's legs, and remove the patient's legs from the arc groove.

[0016] Preferably, step S4 further includes: after placing the patient's leg in the arc-shaped groove, placing an elastic soft pad between the arc-shaped groove and the patient's leg skin.

[0017] By adopting the above-mentioned technical solution, this invention, compared with the prior art, achieves effective restraint of the patient's lower limbs through the setting of the strap assembly and the movement function of the sliding block along the sliding groove. Furthermore, the binding position can be flexibly adjusted according to the wound location. This solves the problem of existing braces failing to restrain the lower limbs, leading to secondary injuries caused by patient shaking, and avoids discomfort caused by direct pressure on the wound from the straps. The strap assembly is only located on one side of the fixed support plate, resulting in a simplified structure that meets the fixation requirements without the need for additional linkage components. The manual lifting assembly, consisting of a sleeve, lifting rod, and locking knob, avoids the costs associated with using electric push rods or complex transmission mechanisms in existing technologies. Addressing issues such as high cost and electrical safety hazards, this lifting structure features fewer parts, simpler assembly, and easier maintenance. The locking knob uses a threaded locking method, ensuring reliable locking and allowing for one-handed operation, meeting the needs of rapid clinical adjustment. The separate design of the fixed and sliding trays allows for flexible adjustment of the distance between them according to the patient's leg length, providing ample operating space for wound care during dressing changes. This solves the problem of existing one-piece support structures failing to adequately expose the wound. The sliding tray's slider and groove mechanism, along with the spring positioning pin and positioning hole engagement, enables 32-position locking of the sliding tray, ensuring precise and reliable distance adjustment. The collection bucket is suspended directly below the dressing change interval via a hanger, making full use of the gravity flow principle to collect waste liquid. No additional diversion device is required. The structure is simple yet the function is complete, effectively reducing environmental pollution during the dressing change process. The overall device has a simple structure, few parts, and a simple assembly process, which can be quickly manufactured and applied in clinical practice. It has extremely high practicality and promotion value. Attached Figure Description

[0019] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments: Example 1

[0020] like Figure 1 As shown, a leg dressing support device for trauma orthopedics includes a base 1, a lifting assembly 2, and a bracket assembly 3.

[0021] The base 1 is a flat, plate-like structure with a certain thickness, made of metal or high-strength engineering plastic to ensure the stability of the overall structure. Universal wheels 7 are installed at the four corners of the bottom of the base 1. Each universal wheel 7 has a locking mechanism; when locked, the base 1 remains in a fixed position and does not slide; when unlocked, the device can move flexibly, facilitating its transfer between different hospital beds.

[0022] The lifting assembly 2 includes a sleeve 21, a lifting rod 22, and a locking knob 23. The lower end of the sleeve 21 is fixedly connected to the center of the upper surface of the base 1, and the sleeve 21 has a hollow cylindrical structure. The lower end of the lifting rod 22 is telescopically inserted into the sleeve 21, and the lifting rod 22 can slide axially within the sleeve 21 to achieve the lifting function. The upper end of the lifting rod 22 is fixedly connected to the fixed support plate 31 in the bracket assembly 3. The locking knob 23 is threaded to the side wall of the sleeve 21. Rotating the locking knob 23 can cause its end to press against or release the side wall of the lifting rod 22, thereby locking or unlocking the telescopic position of the lifting rod 22 relative to the sleeve 21. This lifting assembly 2 adopts a manual mechanical adjustment method, which does not require an external power supply or complex transmission mechanism. It is intuitive to operate, has a low failure rate, and is fully adaptable to the humid and liquid-containing dressing change environment in trauma orthopedic wards, and there are no electrical safety hazards.

[0023] The bracket assembly 3 includes a fixed support plate 31 and a sliding support plate 32. The fixed support plate 31 is fixedly installed on the upper end of the lifting rod 22, and its bottom is fixed to the upper end of the lifting rod 22 by welding or threaded connection. The upper surface of the base 1 has a groove 11 extending along the length of the base, and the sliding support plate 32 is slidably connected to the groove 11. Specifically, a slider 35 is fixedly provided at the bottom of the sliding support plate 32, and the slider 35 is slidably engaged in the groove 11, so that the sliding support plate 32 can slide linearly along the groove 11, thereby adjusting the distance between the sliding support plate 32 and the fixed support plate 31. The bottom of the groove 11 has a plurality of positioning holes 12 arranged at intervals along the extension direction of the groove, and a spring positioning pin 36 is provided on the slider 35. The spring positioning pin 36 selectively engages with the positioning hole 12. When the spring positioning pin 36 is inserted into the positioning hole 12, the position of the sliding support plate 32 is locked. Both the fixed support plate 31 and the sliding support plate 32 have horizontally extending arc-shaped grooves 33 on their upper surfaces. The curvature of the arc-shaped grooves 33 matches the physiological curve of the human leg, effectively distributing leg pressure and improving comfort. The arc-shaped grooves 33 of the fixed support plate 31 and the sliding support plate 32 are aligned on the same straight line, allowing the patient's leg to be supported by both plates simultaneously. A certain distance is maintained between the fixed support plate 31 and the sliding support plate 32 to form a dressing change gap. This gap is used to expose the patient's leg wound and provides ample operating space for medical staff.

[0024] A strap assembly 4 is fixedly mounted on the side of the fixed support plate 31. The strap assembly 4 includes a fixed plate 41 disposed on the side of the fixed support plate 31, a sliding groove 42 formed in the fixed plate 41, a sliding block 43 that limits sliding within the sliding groove 42, and a strap 44 fixedly connected to the sliding block 43. The sliding block 43 matches the cross-sectional shape of the sliding groove 42, ensuring that the sliding block 43 can only slide along the extension direction of the sliding groove 42 and cannot come out of the sliding groove 42. One end of the strap 44 is fixedly connected to the sliding block 43, and the other end of the strap 44 is a free end, which is provided with Velcro, which can be glued to the strap body of the strap 44 to achieve binding. By moving the sliding block 43 along the sliding groove 42, the relative position of the strap 44 and the fixed support plate 31 can be changed, thereby flexibly adjusting the binding point according to the specific location of the patient's leg wound, avoiding direct pressure on the wound site by the strap 44. The strap 44 is preferably made of a medical material with a certain degree of elasticity so as to provide appropriate restraint force without excessive pressure during binding.

[0025] A storage platform 6 is fixedly installed on the side of the lifting rod 22. The storage platform 6 is a horizontal platform used to temporarily place medicines, gauze, tweezers and other items for dressing changes, so that medical staff can easily access them during operation. The storage platform 6 can be designed to be foldable, so that it can be folded up and stored away when not in use to save space. Example 2

[0026] Based on Example 1, this example further adds a waste liquid collection component 5 to meet the collection needs of rinsing fluid and contaminated blood in trauma orthopedic rinsing and dressing change scenarios.

[0027] The waste fluid collection assembly 5 includes a hanger 51 and a collection tank 52. The hanger 51 is fixedly installed on the lifting rod 22 and located below the platform 6. The hanger 51 can adopt a ring hook structure, and the upper edge of the collection tank 52 can be hung on the hanger 51, thus realizing the detachable hanging of the collection tank 52. The opening of the collection tank 52 is located directly below the dressing change gap between the fixed support plate 31 and the sliding support plate 32, so that disinfectant, rinsing fluid, blood oozing and other liquids generated during the dressing change will naturally fall into the collection tank 52 under the action of gravity, effectively avoiding liquid dripping onto the bed or ground and causing pollution. The collection tank 52 is made of transparent material and has scale markings on the tank wall, which makes it easy for medical staff to observe the amount and nature of the collected liquid in real time and help to judge the wound exudation. Example 3

[0028] Based on Embodiment 1 or Embodiment 2, this embodiment further improves the structure of the arc groove 33.

[0029] An elastic pad 34 is detachably installed within the arc-shaped groove 33 of the fixed tray 31 and the sliding tray 32. The elastic pad 34 is made of medical-grade sponge or silicone material, and its shape matches the curved surface of the arc-shaped groove 33. It can be fixed to the arc-shaped groove 33 by Velcro or clips. The elastic pad 34 can be changed after each patient, meeting the requirements for hospital infection control, and improving the comfort of the patient's affected limb during dressing changes, especially suitable for patients with long dressing change times. Several anti-slip protrusions (not shown in the figure) can also be provided on the inner surface of the arc-shaped groove 33 to increase friction with the affected limb and prevent slippage during dressing changes. Example 4

[0030] This embodiment provides a method for using a leg dressing support device in trauma orthopedics, employing the device described in any of the foregoing embodiments, specifically including the following steps: S1: Push the device to the foot of the patient's bed, adjust the position of the device so that the bracket assembly 3 is close to the patient's affected leg, press down on the locking mechanism on the caster wheel 7 to fix the base 1 to the ground and ensure that the device does not slide during dressing changes.

[0031] S2: Based on the patient's leg length (distance from the groin to the ankle), slide the sliding support plate 32 along the groove 11 to adjust the distance between the fixed support plate 31 and the sliding support plate 32. When the sliding support plate 32 moves to the appropriate position, the spring positioning pin 36 on the slider 35 automatically engages with the corresponding positioning hole 12 on the groove 11 under the action of the spring, completing the position locking of the sliding support plate 32. Normally, the fixed support plate 31 should support the thigh, and the sliding support plate 32 should support the lower leg, allowing the knee joint to be naturally suspended during dressing changes, facilitating exposure of wounds in the knee or mid-lower leg.

[0032] S3: Adjust the overall height of the support assembly 3 using the lifting assembly 2, based on the patient's current position and the specific wound location. The specific operation is as follows: Rotate the locking knob 23 counterclockwise to loosen it; pull the lifting rod 22 upwards or press it downwards to the desired height; then rotate the locking knob 23 clockwise until its end presses against the side wall of the lifting rod 22, locking the position of the lifting rod 22 and completing the height adjustment. The goal of the adjustment is to ensure that the patient's leg wound is precisely exposed in the dressing change gap between the fixed support plate 31 and the sliding support plate 32, facilitating dressing changes by medical staff.

[0033] S4: Gently place the patient's affected leg on the arc-shaped groove 33. If an elastic pad 34 is provided, place the elastic pad 34 between the arc-shaped groove 33 and the patient's leg skin. Then, according to the specific location of the leg wound, move the sliding block 43 along the sliding groove 42 to adjust the bandage 44 to a suitable position that will not compress the wound. Then, pull the free end of the bandage 44 around the patient's leg and adhere it to the bandage body to firmly fix the patient's leg on the bracket assembly 3. The tightness of the bandage 44 should be such that it can restrain lower limb shaking but does not cause obvious pressure.

[0034] S5: After removing the collection container 52 from the hanger 51, place it directly below the dressing change interval, or hang the empty collection container 52 directly on the hanger 51, ensuring the opening of the collection container 52 is directly below the dressing change interval. Medical staff then begin the dressing change procedure, including wound cleaning, disinfection, medication application, and dressing replacement. Waste fluid generated during the dressing change process naturally flows into the collection container 52 through the dressing change interval.

[0035] S6: After changing the dressing, first remove the collection bucket 52 for emptying and cleaning. Then loosen the straps 44 to release the fixation on the patient's legs, gently remove the patient's legs from the arc-shaped groove 33, and assist the patient to return to a comfortable position. Finally, remove the elastic cushion 34 for cleaning, disinfection, or replacement, and push the device away from the bed for future use.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
