Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation products, specifically to a multifunctional lower limb injury support device. Background Technology

[0002] Lower limb infections have complex and diverse causes, potentially stemming from trauma, surgical site infections, skin ulcers, inflammation caused by varicose veins, and other conditions. If the local inflammatory response in the lower limbs is not controlled promptly and effectively, the inflammation can continue to spread, leading to an expansion of the infection area and potentially even systemic infection, seriously threatening the patient's life. Therefore, daily care for patients with lower limb infections is extremely important.

[0003] Currently, conventional small pillows and other assistive tools used in the treatment and care of patients with lower limb infections have significant shortcomings. Firstly, these pillows cannot be flexibly adjusted in height according to the severity of the infection. During the treatment of lower limb infections, precise height adjustment based on the location of the injury is crucial for promoting local blood circulation, facilitating infection localization, and preventing further spread of infection throughout the body. However, the fixed height of existing small pillows cannot meet this need. This not only increases the risk of systemic infection but also prolongs hospital stays, significantly increases medical costs, and places a heavy economic and psychological burden on patients and their families.

[0004] On the other hand, regarding the patient's medical experience, patients with lower limb infections are often unable to get out of bed due to their condition, which makes performing procedures such as changing dressings in bed extremely inconvenient. Currently, there is a lack of standardized bed dressing products specifically designed for such patients. Once the infected area breaks and oozes fluid, the fluid can easily leak and contaminate bed sheets, blankets, and other bedding. This not only leads to a very poor patient experience but also increases the workload of nurses, as they need to frequently change contaminated sheets and blankets, resulting in a serious waste of medical resources.

[0005] Therefore, the present invention provides a multifunctional lower limb injury support device to suit the lower limb support needs of different patients, reduce the incidence of complications, facilitate rapid patient recovery, and thus reduce patient hospitalization costs. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a multifunctional lower limb injury support device suitable for the lower limb support needs of different patients, reducing the incidence of complications, facilitating rapid patient recovery, and thereby reducing patient hospitalization costs.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A multifunctional lower limb injury support device includes a base plate, on which a support frame for supporting and placing the patient's legs is detachably connected. From left to right, the base plate is provided with a massage and decompression mechanism for precisely decompressing the patient's back, a lifting mechanism for adjusting the height of the patient's knee and ankle joints, and a support and massage mechanism for precisely adjusting the height of the lower limbs locally or as a whole.

[0008] The lifting mechanism includes a support block, and both sides of the support block are fixedly connected to a first telescopic rod for adjusting the support height; the lifting and massage mechanism includes a second telescopic rod fixedly connected to the bottom top, and a second mounting rod is fixedly connected between the first telescopic rod and the second telescopic rod. The second mounting rods are symmetrically arranged with the base plate as the center, and the lifting frame is located between adjacent second mounting rods.

[0014] A roller is rotatably fitted inside the baffle, and a drainage membrane is wound on the roller. The drainage membrane is fixedly connected to the baffle. When the baffle is parallel to the bottom plate, the baffle is located above the drainage rod; when the baffle is perpendicular to the bottom plate, the baffle is located between the first telescopic rod and the second telescopic rod.

[0015] Furthermore, the recycling mechanism includes a drainage groove at the top of the drainage rod, and a circular collection channel inside the drainage groove. A clamping block is slidably fitted inside the collection channel, and the clamping block is in clearance fit with the collection channel.

[0016] A drain pipe is fixedly connected to the side of the base plate away from the support block, and the drain pipe is connected to the collection channel through a water pipe.

[0017] Furthermore, the lifting massage mechanism also includes a first mounting rod located above the base plate and several third telescopic rods located on both sides of the top of the base plate. The end of the third telescopic rod away from the base plate is fixedly connected to a support block. The first mounting rod is located between adjacent support blocks, and the first mounting rod is fitted with the support block with a clearance.

[0018] Several sliding grooves are opened on the base plate. The sliding grooves are symmetrically arranged with the base plate as the center. A first slider is slidably fitted in the sliding groove. The first slider is fixedly connected to the third telescopic rod.

[0019] A protruding block is fixedly connected to the first mounting rod, and a roller is slidably fitted on the first mounting rod. The roller is fixedly connected to the first mounting rod through the protruding block, and a traction rope for traction of the patient's leg is wound on the roller.

[0020] Furthermore, a soothing mechanism is also provided inside the base plate. The soothing mechanism includes a fourth mounting rod, with a second slider fixedly connected to both ends of the fourth mounting rod. The second slider is located in the slide groove and slides in cooperation with the slide groove.

[0021] A massage block is slidably fitted on the fourth mounting rod. Several expansion bladders are rotatably fitted on the top of the massage block. The expansion bladders are symmetrically arranged around the massage block. Several massage rollers are provided between adjacent expansion bladders. The massage rollers correspond to the positions of the expansion bladders. A connecting rod is rotatably fitted on one end of each massage roller. The connecting rod is rotatably fitted with the massage block. The connecting rod and the massage block are detachably connected. The expansion bladders are connected to a blower through an air pipe for controlling the expansion and contraction of the expansion bladders.

[0022] Furthermore, the distance between the second telescopic rod and the center of the base plate is less than the distance between the first telescopic rod and the center of the base plate.

[0023] Furthermore, a movable rod is also fitted on the first mounting rod with clearance, and a second mating rod is coaxially fitted to the end of the movable rod away from the first mounting rod.

[0024] Furthermore, a third mounting rod is provided between adjacent second telescopic rods. The two ends of the third mounting rod are fixedly connected to arc-shaped locking blocks, which are fully fitted with the second telescopic rods. A sliding groove is opened inside the third mounting rod, and a third slider is slidably fitted inside the sliding groove. A pin is provided between the third slider and the third mounting rod. A foot pad is rotatably fitted on the side of the third slider near the support block.

[0025] The above approach has the following beneficial effects:

[0026] 1. This treatment plan allows for precise height adjustment based on the severity of lower limb infections and acute lower limb trauma, facilitating the localization of infection, preventing its spread, reducing the risk of systemic infection, and lowering hospitalization costs. Furthermore, it is designed based on anatomical principles to improve patient comfort.

[0027] 2. This plan is designed for patients with lower limb infections who are unable to move around on their own. It helps medical staff to change dressings for patients in a standardized manner while they are in bed, preventing leakage of fluid from the lesions on the lower limbs and contaminating the sheets and blankets. This reduces the waste of medical resources, reduces the repetitive workload of nurses, and improves the medical experience for patients with lower limb infections.

[0028] 3. This plan addresses the risk of deep vein thrombosis in the lower extremities due to prolonged bed rest. Based on clinical assessments, this plan provides segmented lower extremity massage to prevent venous thrombosis. It also addresses the risk of pressure injuries by providing precise, small-area decompression to prevent pressure injuries.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description illustrates the specific implementation method:

[0042] As attached Figures 1 to 7As shown: A multifunctional lower limb injury support device includes a base plate 1 for placement on a bed. A support frame for supporting the patient's legs is detachably connected to the base plate 1. In this embodiment, the support frame is a prior art device, such as a Thomas frame with the bottom suspended. From left to right, the base plate 1 is provided with a massage and decompression mechanism for precise decompression of the patient's back, a lifting mechanism for adjusting the height of the patient's knee and ankle joints, and a support and massage mechanism for precise adjustment of the height of the lower limbs locally or as a whole.

[0043] The massage and decompression mechanism includes a reclining board 11 fixedly connected to a base plate 1. Several inflatable decompression bladders 12 are fixedly connected to the reclining board 11. Each decompression bladder 12 is connected to a conduit, and each conduit is connected to a solenoid valve. The end of the conduit furthest from the decompression bladder 12 is connected to an air compressor (not shown in the figure). In another embodiment, the end of the conduit furthest from the decompression bladder 12 is connected to a water pump. The pumping power of the air compressor and water pump is used to pump air or liquid to inflate the decompression bladders 12, providing a buffer layer to reduce direct pressure on the patient's back against the hard bed, thus reducing the pressure on the back after leg elevation. Simultaneously, by controlling the expansion of the decompression bladders 12 at different positions, different levels of elevation are created on the patient's back to reduce the risk of pressure sores caused by prolonged pressure, thereby ensuring patient comfort. Adjusting the expansion position of the decompression bladders 12 allows for precise small-area decompression, achieving precise decompression treatment and preventing pressure injuries.

[0044] The lifting mechanism includes a support block 2, with first telescopic rods 13 for adjusting the support height fixedly connected to both sides of the support block 2. The support block 2 includes a central block 21, with both ends of the central block 21 fixedly connected to the output ends of the first telescopic rods 13. A first block 22 and a second block 23 are rotatably fitted to both sides of the central block 21, and the first block 22 and the second block 23 are symmetrically arranged with the central block 21 as the center. Several retractable first engaging rods 24 are hinged to the side of the first block 22 away from the central block 21, and the end of the first engaging rod 24 away from the first block 22 is rotatably fitted to the reclining board 11. The lifting massage mechanism includes a second telescopic rod 14 fixedly connected to the bottom top. A second mounting rod 4 is fixedly connected between the first telescopic rod 13 and the second telescopic rod 14. The second mounting rods 4 are symmetrically arranged with the base plate 1 as the center, and the lifting frame is located between adjacent second mounting rods 4. The two sides of the lifting frame are engaged with the second mounting rods 4. In another embodiment, collars (not shown in the figure) are fixedly connected to both ends of the central block 21. The collars engage with the output end of the first telescopic rod 13 to facilitate the fixing and installation of the central block 21 and the first telescopic rod 13, and to facilitate replacement during actual use. In yet another embodiment, a mating hole (not shown in the figure) is opened at the top of the first telescopic rod 13. A mating block (not shown in the figure) is slidably fitted inside the mating hole. The mating block is fixedly connected to the side wall of the second mounting rod 4. During the installation of the second mounting rod 4 and the first telescopic rod 13, the sliding fit between the mating holes facilitates the disassembly and installation of the second mounting rod 4 and the first telescopic rod 13, meeting the needs of actual use.

[0045] The lifting and massage mechanism includes a baffle 41 that slides with the second mounting rod 4 and a drainage rod 7 located at the center of the base plate 1. One end of the drainage rod 7 is hinged to the side of the second block 23 away from the center block 21. A central rotating rod is slidably fitted to the end of the drainage rod 7 near the second block 23. The central rotating rod is rotatably fitted to the second block 23, and the extension length is adjusted by the central rotating rod to ensure the connection to the support block 2. The other end of the drainage rod 7 is hinged to the side of the base plate 1 near the second telescopic rod 14. A roller is rotatably fitted inside the baffle 41, and a drainage membrane 44 is wound on the roller. The drainage membrane 44 is fixedly connected to the baffle 41. When the baffle 41 is parallel to the base plate 1, the baffle 41 is located above the drainage rod 7. When the baffle 41 is perpendicular to the base plate 1, the baffle 41 is located between the first telescopic rod 13 and the second telescopic rod 14.

[0046] Between adjacent second mounting rods 4, there is a collection mechanism for collecting disinfectant during patient dressing changes. The collection mechanism includes a drainage groove 71 at the top of the drainage rod 7, and a circular collection channel inside the drainage groove 71. A clamping block 73 is slidably fitted inside the collection channel, and the clamping block 73 is in clearance fit with the collection channel. A drain pipe 72 is fixedly connected to the side of the base plate 1 away from the support block 2. The drain pipe 72 is connected to the collection channel through a water pipe.

[0047] The lifting and massage mechanism also includes a first mounting rod 3 located above the base plate 1 and several third telescopic rods 32 located on both sides of the top of the base plate 1. The end of the third telescopic rod 32 away from the base plate 1 is fixedly connected to a support block. The first mounting rod 3 is located between adjacent support blocks and is clearance-fitted with the support block. Several sliding grooves are opened on the base plate 1, and the sliding grooves are symmetrically arranged with the base plate 1 as the center. A first slider is slidably fitted in the sliding groove and is fixedly connected to the third telescopic rod 32. A protruding block is fixedly connected to the first mounting rod 3, and a roller 31 is slidably fitted on the first mounting rod 3. The roller 31 is fixedly connected to the first mounting rod 3 through the protruding block, and a traction rope for traction of the patient's legs is wound on the roller 31.

[0048] A first reinforcing rod 42 is fixedly connected between the first telescopic rod 13 and the second telescopic rod 14. A telescopic second reinforcing rod 43 is provided between the first reinforcing rod 42 and the second mounting rod 4. The second reinforcing rod 43 is located between adjacent baffles 41.

[0049] The connection between the first reinforcing rod 42 and the second reinforcing rod 43 is strengthened, thereby improving the support stability of the second mounting rod 4.

[0050] In this embodiment, the first telescopic rod 13, the second telescopic rod 14, the third telescopic rod 32, the first mating rod 24, and the second reinforcing rod 43 are all common sleeve mechanisms. The sleeve mechanism includes a first tube and a second tube, which are slidably fitted together, and a bolt connection is provided between the first tube and the second tube.

[0051] The specific implementation process is as follows:

[0052] For patients with lower limb infections and acute lower limb trauma, the height can be precisely adjusted according to the severity of the infection through the adjustment of the first telescopic rod 13 and the second telescopic rod 14. This helps to limit the infection, prevent its spread, reduce the risk of systemic infection, and lower hospitalization costs. Furthermore, the design, based on human anatomy, improves patient comfort.

[0053] Most patients with lower limb infections are unable to walk independently. Since the knee joint is at its highest point when the leg is bent, the height of the first telescopic rod 13 is adjusted to match the height of the patient's leg. This also facilitates maintaining the leg's elevated position. Simultaneously, during support, the first block 22 and the second block 23, which rotate around the central block 21, accommodate changes in the angle of the thigh and lower leg around the knee joint, improving comfort during knee support. Furthermore, the telescopic first cooperating rod 24 accommodates changes in the lifting of the support block 2. The support plane formed by multiple first cooperating rods 24 maintains support for the patient's thigh, reducing the possibility of the thigh being suspended and improving patient comfort.

[0054] The drainage rod 7 further assists in supporting the support block 2, ensuring the stability of the support at both ends of the support block 2, thereby ensuring the stable support of the support block 2 for the knee joint. At the same time, by utilizing the rotational cooperation between the baffle 41 and the second mounting rod 4, the baffle 41 forms a dressing platform on the bed surface to support the lower leg during dressing changes, assisting medical staff in performing dressing changes for patients in a standardized manner on the bed. The drainage membrane 44 covers the bed surface to prevent leakage of fluid from the lower limb lesions from contaminating the sheets and blankets, reducing the waste of medical resources, reducing the repetitive workload of nurses, and improving the medical experience for patients with lower limb infections.

[0055] During the lifting of support block 2, the second block 23 raises the drainage rod 7 to form an inclined drainage channel 71, facilitating the collection of disinfectant or exudate within the drainage channel 71 into the drain pipe 72. A drainage membrane 44 inside the baffle 41 is placed within the drainage channel 71 to block and drain the fluid. A clamping block 73 moves within the collection channel, holding the drainage membrane 44 to the bottom of the channel to ensure stable and continuous drainage, thus facilitating the stable collection of disinfectant or exudate. This solution helps medical staff to perform standardized dressing changes for patients in bed, preventing leakage and contamination of bed sheets and blankets from lower limb lesions, reducing waste of medical resources, minimizing repetitive workload for nurses, and improving the patient experience for patients with lower limb infections.

[0056] Meanwhile, the roller 31 slides on the first mounting rod 3 to adjust its position in the width direction of the base plate 1. The first slider slides in the groove to adjust the position of the first mounting block in the length direction of the base plate 1 to meet the patient's leg traction needs and improve the convenience of use. The first mounting rod 3 rotates on the support block, and the protruding block drives the roller 31 to rotate, so that the length of the traction rope wound on the roller 31 can be adjusted to meet the support needs of different leg support heights.

[0057] In another embodiment, the base plate 1 is further provided with a soothing mechanism, which includes a fourth mounting rod 6. The two ends of the fourth mounting rod 6 are fixedly connected to second sliders, which are located in a slide groove and slide in cooperation with the slide groove. A massage block 61 is slidably fitted on the fourth mounting rod 6. A plurality of expansion bladders 62 are rotatably fitted on the top of the massage block 61. The expansion bladders 62 are symmetrically arranged around the massage block 61. A plurality of massage rollers 63 are provided between adjacent expansion bladders 62. A plurality of protrusions are fixedly connected on the massage rollers 63. The massage rollers 63 correspond to the positions of the expansion bladders 62. A connecting rod 64 is rotatably fitted on one end of the massage roller 63. The connecting rod 64 is rotatably fitted with the massage block 61 and is detachably connected to the massage block 61. The expansion bladders 62 are connected to a blower for controlling the expansion and contraction of the expansion bladders 62 through an air pipe.

[0058] The massage block 61 slides on the fourth mounting rod 6, and the fourth mounting rod 6 slides within the groove, adjusting the contact position between the massage block 61 and the patient's leg to suit the different massage and relaxation needs of various patients. During the massage, a blower repeatedly drives the expansion bladder 62 to contract and expand, driving the massage roller 63 to squeeze and roll on the patient's leg. The repeated contraction and expansion of the expansion bladder 62 simulates the repeated squeezing of a human hand, improving patient comfort during use.

[0059] During use, the connecting rod 64 and massage roller 63 can be disassembled according to the location of the patient's leg wound to reduce irritation to the wound area. Furthermore, the trachea at the connection point of the expansion bladder 62 can be connected to further reduce irritation to the wound area and improve the device's adaptability. Since prolonged bed rest can easily lead to deep vein thrombosis in the lower extremities, segmented lower extremity massage can be implemented based on clinical assessments to prevent venous thrombosis. Additionally, pressure injuries are also common; this solution provides precise, small-area decompression to prevent pressure injuries.

[0060] In another embodiment, the distance between the second telescopic rod 14 and the center of the base plate 1 is less than the distance between the first telescopic rod 13 and the center of the base plate 1. By changing the support position of the first telescopic rod 13 and the second telescopic rod 14, the end of the second mounting rod 4 away from the first telescopic rod 13 retracts towards the center to adapt to the shape of the patient's leg, thereby improving the stability and adaptability during the subsequent installation of the support frame.

[0061] In another embodiment, a movable rod 33 is also fitted on the first mounting rod 3 with clearance. The end of the movable rod 33 away from the first mounting rod 3 is coaxially rotatably fitted with a second mating rod 34. In this embodiment, a bolt is threadedly connected between the movable rod 33 and the first mounting rod 3. The movable rod 33 is fixed in position by the bolt abutting against the first mounting rod 3.

[0062] The sliding engagement of the movable rod 33 on the first mounting rod 3 allows for adjustment of the distance between the second engaging rod 34 and the second mounting rod 4, adapting to the leg spacing support needs of different patients. The rotation engagement of the second engaging rod 34 on the movable rod 33 allows for adjustment of the rotation angle of the second engaging rod 34, ensuring that the shapes of the second engaging rod 34 and the second mounting rod 4 are symmetrically arranged to facilitate the placement and installation of the support frame.

[0063] In another embodiment, a third mounting rod 5 is provided between adjacent second telescopic rods 14. The two ends of the third mounting rod 5 are fixedly connected to arc-shaped locking blocks 51, and the locking blocks 51 are fully engaged with the second telescopic rods 14. A sliding groove is opened in the third mounting rod 5, and a third slider 53 is slidably engaged in the sliding groove. A pin (not shown in the figure) is provided between the third slider 53 and the third mounting rod 5. The side of the third slider 53 near the support block 2 is rotatably engaged with a foot pad 52.

[0064] The third mounting rod 5 is detachably connected to the second telescopic rod 14 by the locking block 51, thereby facilitating the disassembly and installation of the third mounting rod 5. The third slider 53 is used for sliding engagement to adjust the support position of the foot pad 52, so as to provide support for the patient's feet and improve the patient's comfort.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
