Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional back wound aid. Background Technology

[0002] In the treatment of patients with extensive burns, wounds on the back usually heal more slowly, requiring patients to stay in bed for extended periods. Combined with pain, patients often resist sitting or turning over, leading to insufficient and inadequate exposure of the back wound during dressing changes and affecting the effectiveness of medications (medications are easily washed away by dressings, and excessive secretions hinder their effectiveness). Delayed healing of back wounds prolongs the patient's bed rest time, increasing the incidence of complications such as hypostatic pneumonia, deep vein thrombosis in the lower extremities, and foot drop.

[0003] During long-term treatment, it was found that existing practices, such as frequent turning or using a turning bed, along with some assistive devices, can reduce the occurrence of complications. However, these practices are limited by the patient's cooperation and their effectiveness is greatly reduced. In clinical practice, due to various factors, the prevention of complications cannot be strictly implemented, and the workload of nurses is also increased, so this problem has not been well solved. Therefore, it is necessary to propose a multifunctional back wound assist device to provide a new technical solution to solve the technical problems mentioned in the above patent.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] As mentioned in the background section, during long-term treatment, it has been found that the current practice is to reduce the occurrence of complications by frequently turning the patient over or using a turning bed, and by using some assistive devices. However, the effectiveness of these practices in wound treatment is limited by the patient's cooperation and is greatly reduced. In clinical practice, due to various factors, the prevention of complications cannot be strictly implemented, and the workload of nurses will also increase, so this problem has not been well resolved.

[0041] To address this technical problem, the present invention provides a multifunctional back wound assist device that allows patients to maintain a sitting position in bed, thereby increasing the exposed area of ​​the patient's back. It can also raise the patient's hands, thereby fully exposing both armpits. This not only improves patient cooperation but also reduces the workload of nursing staff.

[0042] For details, please refer to Figures 1-2 A multifunctional back wound assist device specifically includes: a movable box 1, two movable boxes 1 arranged symmetrically, a movable groove opened on the inner side of the movable box 1, a fixed component 2 slidably connected to the bottom of each of the two movable boxes 1, a power component 3 set on the top of the movable box 1, and the bottom sides of the power component 3 are fixedly connected to the two movable boxes 1, an upper limb flipping component 4 set at one end of the movable box 1, and a lower limb movement component 5 set at the other end of the movable box 1.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0044] Example 1:

[0045] Please refer to Figures 1-4 A multifunctional back wound assist device includes two movable boxes 1 arranged symmetrically. The movable boxes 1 have an inner groove. The bottom of each movable box 1 is slidably connected to a fixing component 2. The top of each movable box 1 is provided with a power component 3, and the bottom sides of the power component 3 are fixedly connected to the two movable boxes 1. One end of each movable box 1 is provided with an upper limb flipping component 4, and the other end of each movable box 1 is provided with a lower limb movement component 5.

[0046] When in use, the fixed component 2 can be used to fix the mobile box 1 to both sides of the bed, which makes it easier to perform subsequent operations on the patient.

[0047] Subsequently, through the setting of the power component 3, the upper limb rotation component 4 and the lower limb movement component 5 can be selectively driven to work. When the power component 3 drives the upper limb rotation component 4 to work, the patient's back can be lifted up, so that the patient can maintain a sitting position on the bed, which makes it easier for nursing staff to perform subsequent operations on the patient's back. When the power component 3 drives the lower limb movement component 5 to work, rehabilitation exercises can be performed on the patient's legs, thereby improving the patient's rehabilitation effect.

[0048] The fixed component 2 includes a concave box 6, a first threaded rod 7, a pressing plate 8, and a slide bar 9. The bottom of the movable box 1 is provided with a concave box 6, and the two concave boxes 6 are arranged symmetrically. The bottom of the concave box 6 is threadedly connected to the first threaded rod 7, and the first threaded rod 7 passes through the bottom of the concave box 6 and is fixedly connected to a drive handle. The end of the first threaded rod 7 located inside the concave box 6 is rotatably connected to the pressing plate 8. The two ends of the top of the concave box 6 are fixedly connected to the slide bar 9, and the slide bar 9 is slidably connected to the bottom of the movable box 1.

[0049] Specifically: In use, the concave box 6 can be placed on both sides of the bed. Then, the first threaded rod 7 can be rotated by turning the handle, thereby moving the compression plate 8 upward and squeezing the bottom of both sides of the bed. At this time, the compression plate 8, together with the top of the inner side of the concave box 6, will clamp the two sides of the bed, thereby achieving the effect of fixing the device. After fixing the concave box 6, the distance between the moving box 1 and the patient's body can be adjusted by sliding the slider 9 to the bottom of the moving box 1, so that the device can adapt to patients of various body types.

[0050] The power assembly 3 includes a support vertical rod 10, a support horizontal rod 11, a dual-head motor 12, a first rotating shaft 13, baffles 14, a winding rope 15, and a first hook 16. The tops of the two movable boxes 1 are fixedly connected to the support vertical rods 10 on opposite sides. A support horizontal rod 11 is provided between the tops of the two support vertical rods 10, and both sides of the support horizontal rod 11 are fixedly connected to the two support vertical rods 10. A dual-head motor 12 is fixedly connected to the center of the top of the support horizontal rod 11. The output ends of both sides of the dual-head motor 12 are fixedly connected to the first rotating shaft 13. Two baffles 14 are fixedly connected to both sides of the top of the support horizontal rod 11, and each pair of baffles 14 is rotatably connected to each first rotating shaft 13. A winding rope 15 is wound around the outer side of the first rotating shaft 13 on the side away from the dual-head motor 12, and the end of the winding rope 15 near the first rotating shaft 13 is located between the two baffles 14. The end of the winding rope 15 away from the first rotating shaft 13 is fixedly connected to the first hook 16.

[0051] Specifically: In use, the first hook 16 can be hooked onto the inside of the upper limb flipping component 4 or the lower limb movement component 5. Then, by turning on the dual-head motor 12, the first rotating shaft 13 can be driven to rotate inside the baffle 14. The first rotating shaft 13 can then drive the winding rope 15 to wind and rewind. At the same time, the two baffles 14 can keep the winding rope 15 between the two baffles 14 during the winding and rewinding process, thereby preventing the winding rope 15 from deviating during the winding and rewinding process. At this time, the winding rope 15 can drive the first hook 16 at the end to perform the winding and unwinding operation, thereby enabling the device connected to the first hook 16 to work.

[0052] Example 2:

[0053] This embodiment 2 further discloses the specific structure of the upper limb rotation component 4 based on the above embodiments. By cooperating with the structure in the above embodiments, the upper limb rotation component 4 enables the patient to maintain a sitting position on the bed, thereby increasing the area of ​​the patient's back exposed. At the same time, it can also raise the patient's hands, thereby fully exposing both armpits. This not only improves the patient's cooperation but also reduces the workload of nursing staff.

[0054] The multifunctional back wound aid provided in Example 1 has been further optimized, specifically, as follows: Figures 5-10 As shown, the upper limb flipping assembly 4 includes a first rotating seat 17, a first rotating plate 18 and a sliding rod 22. The first rotating seat 17 is fixedly connected to one end of the moving box 1. The first rotating plate 18 is rotatably connected to the end of the first rotating seat 17 away from the moving box 1.

Multiple second toothed blocks 27 are fixedly connected to the inner side of the limiting groove, and the end of the second flipping plate 26 away from the third rotating seat 25 is compression-limited with the second toothed block 27.

[0056] The upper limb flipping assembly 4 also includes a rotating disk 28, a fixed rod 29, a driving plate 30, a second threaded rod 31, a first handle 32, and a concave insert plate 33. A rotating groove is provided on the inner side of the sliding rod 22 near the moving box 1. The rotating disk 28 is rotatably connected to the bottom of the inner side of the rotating groove. Fixed rods 29 are fixedly connected to both sides of the top of the rotating disk 28. A driving plate 30 is provided on the top of the rotating disk 28, and sliding holes are provided on both sides of the driving plate 30. The two sliding holes are slidably connected to the outer sides of the two fixed rods 29. The second threaded rod 31 is fixedly connected to the top of the driving plate 30, and the top of the second threaded rod 31 passes through the top of the rotating groove and is threadedly connected to the sliding rod 22. The first handle 32 is fixedly connected to the end of the second threaded rod 31 located at the top of the sliding rod 22. Multiple slots are provided on both sides of the bottom of the first rotating plate 18. Concave insert plates 33 are provided on both sides of the rotating groove. The top of the concave insert plate 33 is rotatably connected to the fixed rod 29, and the bottom of the concave insert plate 33 is inserted into the slot for limiting.

[0057] The upper limb flipping assembly 4 also includes a placement box 34, a third threaded rod 35, a second handle 36, a fourth rotating seat 37, a support pad 38, and a fifth rotating seat 39. The placement box 34 is located at the end of the sliding rod 22 furthest from the movable box 1. A sliding groove is formed at the end of the placement box 34 near the sliding rod 22, and the end of the sliding rod 22 near the placement box 34 is slidably connected to the sliding groove. The third threaded rod 35 is rotatably connected to the inner side of the sliding groove, and the third threaded rod 35 is threadedly connected to the sliding rod 22. One side of the third threaded rod 35 passes through… The third threaded rod 35 passes through the side wall of the sliding groove and extends to the outside of the placement box 34. The end of the third threaded rod 35 located on the outside of the placement box 34 is fixedly connected to the second handle 36. The side of the placement box 34 away from the second handle 36 is fixedly connected to the fourth rotating seat 37. A support pad 38 is provided between the two placement boxes 34, and both sides of the support pad 38 are rotatably connected to the two fourth rotating seats 37. The top of the placement box 34 near the second handle 36 is fixedly connected to the fifth rotating seat 39, and the fifth rotating seat 39 is hooked to the first hook 16.

[0058] Specifically: the support pad 38 is made of a hard material that is not easily deformed, such as hard plastic.

[0059] When in use, the support pad 38 can be placed under the patient's neck, at which point the placement box 34 will be positioned on both sides of the patient's head and shoulders.

[0060] The device can then be adjusted according to the patient's body shape. By rotating the second handle 36, the third threaded rod 35 can be rotated inside the sliding groove, thereby causing the sliding rod 22, which is threadedly connected to the third threaded rod 35, to adjust its position inside the sliding groove inside the placement box 34. This allows the distance between the two sliding rods 22 to be adjusted to fit the width of the patient's body. As the sliding rod 22 moves, the end of the sliding rod 22 away from the placement box 34 will cause the moving box 1 to slide synchronously on the top of the concave box 6, thus keeping the sliding rod 22 at a parallel angle to the patient, which facilitates subsequent operations such as sitting up the patient.

[0061] Simultaneously, the sliding rod 22 can be slid laterally on the top of the first rotating plate 18 according to the patient's height. After the sliding rod 22 and the first rotating plate 18 are adjusted to a suitable position for the patient, the first handle 32 can be rotated. The first handle 32 drives the second threaded rod 31 to rotate inside the rotating groove. Through the threaded connection between the second threaded rod 31 and the sliding rod 22, the second threaded rod 31 will continuously descend during its rotation, driving the driving plate 30 at the bottom of the second threaded rod 31 to rotate and descend synchronously. At this time, the driving plate 30... The sliding holes on both sides of the slide rod 29 will cause the two fixed rods 29 to move, and cause the rotating disk 28, which is fixedly connected to the two fixed rods 29, to rotate adaptively at the bottom of the rotating groove. At the same time, during the movement of the two fixed rods 29, they will move from both sides of the rotating groove to the center of the rotating groove, thereby causing the two concave insert plates 33 to move closer to the second threaded rod 31, and causing the bottom of the concave insert plates 33 to be inserted into the slots opened at the bottom of both sides of the first rotating plate 18 for limiting, thereby achieving the effect of fixing the sliding rod 22 and the first rotating plate 18.

[0062] By using the fit between the side walls of the first rotating plate 18 and the middle of the concave insert plate 33, the phenomenon of large displacement of the concave insert plate 33 during movement can be avoided, and the bottom of the concave insert plate 33 can be smoothly inserted into the slots opened at the bottom of the first rotating plate 18 on both sides, thereby achieving the insertion and limiting effect.

[0063] By fixing the fixed rod 29 to the rotating disk 28, the rotating disk 28 is driven to rotate synchronously at the bottom of the rotating groove. At the same time, the two sides of the driving plate 30 will slide downward outside the fixed rod 29. By setting the fixed rod 29 and the driving plate 30, a space can be reserved between the second threaded rod 31 and the rotating disk 28, so as to avoid the bottom of the second threaded rod 31 being blocked and affecting the movement path of the second threaded rod 31 when it rotates.

[0064] After fixing the lengths of the first rotating plate 18 and the sliding rod 22, the first hook 16 can be hooked onto the outside of the fifth rotating seat 39, thereby turning on the dual-head motor 12 to drive the first hook 16 to move. This allows the first hook 16 to pull the fifth rotating seat 39, and simultaneously rotate the first rotating plate 18, the sliding rod 22, the placement box 34, and the support pad 38. The support pad 38 provides support to the patient's neck, making the patient sit up. At the same time, the first rotating plate 18 and the sliding rod 22 provide support to the patient's upper limbs during the rotation.

[0065] After the patient is seated, the first flip plate 24 can be adjusted to be parallel to the bed surface. Then, the second flip plate 26 is rotated, and the end of the second flip plate 26 away from the third rotating seat 25 is inserted into the inside of the second toothed block 27. Through the limiting setting of the second flip plate 26 and the second toothed block 27, the first flip plate 24 can be supported, thereby supporting the patient's upper limbs and fully exposing both armpits, thus reducing the workload of nursing staff.

A second hook 59 is fixedly connected to the end of the toothed plate 58 near the ninth rotating seat 57, and the second hook 59 is hooked to the ninth rotating seat 57.

[0071] The lower limb movement assembly 5 also includes a top plate 60, a slider 61, a second rotating shaft 62, a third handle 63, a synchronous belt 64, an elliptical disc 65, a first magnet 66, and a second magnet 67. The top plate 60 is located inside the movable groove, below the toothed plate 58, and provides support for the toothed plate 58. Slider 61s are fixedly connected to both ends of the top plate 60, and the top plate 60 is slidably connected to both sides of the movable groove via the sliders 61s. A second rotating shaft 62 is rotatably connected to the bottom of both ends of the movable groove. One of the second rotating shafts 62 penetrates the sidewall of the movable groove and extends to the outside of the movable box 1. A third handle 63 is fixedly connected to the end of the shaft 62 located on the outside of the movable box 1. A drive groove is opened at the bottom of the movable box 1 near the third handle 63, and the drive groove and the movable groove are connected. A synchronous belt 64 is provided inside the drive groove, and both ends of the synchronous belt 64 are rotatably connected to two second rotating shafts 62. An elliptical disk 65 is fixedly connected to the outside of the second rotating shaft 62 located inside the movable groove. A first magnet 66 is fixedly connected to the end of the elliptical disk 65 away from the second rotating shaft 62. A second magnet 67 is fixedly connected to both sides of both ends of the movable groove, and the second magnet 67 and the first magnet 66 are magnetically connected.

[0072] Specifically: In use, the patient's foot can be placed on top of the right-angle plate 54 and fixed by the second fixing sleeve 56. Then, the patient's knee can be fixed by the first fixing sleeve 48. At this time, through the sliding connection of the second rotating plate 41, the first adapting plate 45 and the first connecting plate 46, and in conjunction with the sliding connection of the third rotating plate 50, the second adapting plate 51 and the second connecting plate 52, the system can automatically adjust according to the patient's leg length after the patient's foot is fixed. At the same time, in conjunction with the first telescopic rod 47 and the second telescopic rod 53, the comfort of fixing the patient's knee position and foot can be improved.

[0073] When the first hook 16 is hooked onto the outside of the eighth rotating seat 55, the right angle plate 54 can be rotated around the second telescopic rod 53 by pulling the first hook 16, thereby achieving the purpose of performing foot and ankle exercises on the patient.

[0074] For patients who are close to recovery or have small burn areas, it is also possible to perform large-scale rehabilitation exercises on their legs.

[0075] Specifically: the first hook 16 can be hooked onto the outside of the seventh rotating seat 49. The first hook 16 can be driven by the double-headed motor 12 to lift the patient's knee position, thereby enabling the patient to perform large-amplitude movements such as bending the leg. At the same time, the rotation of the double-headed motor 12 can be adjusted to adaptively adjust the range of motion of the patient's leg.

[0076] For patients with large body weight, the second hook 59 at the end of the dental plate 58 can be hooked to the outside of the ninth rotating seat 57 at the bottom of the second adaptation plate 51. Then, by rotating the third handle 63, the elliptical disk 65 located inside the movable groove of the second rotating shaft 62 can be rotated.

[0077] By setting the timing belt 64, when one of the second rotating shafts 62 is rotated, the other second rotating shaft 62 can also be driven to rotate synchronously, and the elliptical disk 65 can be flipped from a flat position to an upright position.

[0078] The elliptical shape of the elliptical disk 65 allows the top plate 60 to be lifted during the flipping process, enabling it to slide upwards inside the movable groove and exert a squeezing effect on the bottom of the toothed plate 58.

[0079] By setting the top plate 60, when the toothed plate 58 is lifted, the toothed plate 58 and the second gear 43 can mesh. When the toothed plate 58 is not lifted, the meshing effect between the toothed plate 58 and the second gear 43 can be canceled.

[0080] By setting the slider 61, the movement of the top plate 60 inside the movable groove can be limited, preventing the top plate 60 from leaving the range inside the movable groove during movement.

[0081] After the elliptical disk 65 is flipped into an upright state, the first magnet 66 on the inner side of the elliptical disk 65 will come into contact with the second magnet 67. Through the magnetic attraction between the first magnet 66 and the second magnet 67, the elliptical disk 65 can be kept in an upright state and exert a continuous squeezing effect on the top plate 60, thereby maintaining the meshing effect between the toothed plate 58 and the second gear 43.

[0082] Then, the second motor 44 is turned on, which drives the second gear 43 to rotate. While the second gear 43 is rotating, the third tooth block 42 meshes with the second gear 43, causing the second rotating plate 41 to rotate around the second gear 43. This works in conjunction with the first hook 16 to pull the patient's knee, resulting in the effect of synchronously rotating the patient's thigh.

[0083] While the second gear 43 rotates, it can also drive the toothed plate 58 meshing with the second gear 43 to move laterally inside the movable groove. Through the setting of the second hook 59 at the end of the toothed plate 58, it pulls the ninth rotating seat 57 to move synchronously, thereby driving the bottom of the second adapting plate 51 to move laterally synchronously, thus achieving the effect of allowing the patient's leg to move significantly.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
