Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical bedside nursing auxiliary equipment technology, specifically relating to an adjustable device for changing dressings for patients with complex, slow-healing wounds at the bedside. Background Technology
[0002] In recent years, the number of patients with complex, slow-healing wounds such as diabetic foot, pressure injuries, and postoperative non-healing wounds has been gradually increasing. Bedside debridement, irrigation, disinfection, medication application, and bandaging are common nursing procedures in clinical practice. Currently, bedside dressing changes typically involve placing medications on a nursing cart, and using pillows, trays, simple supports, or manual limb support to support the patient's limbs. Waste fluids are usually temporarily collected using nursing pads, kidney dishes, or drip trays.
[0003] Currently, the above methods still have shortcomings in practical use: complex chronic wounds are often located in areas that are not easily exposed, such as the lower leg, heel, and ankle. The height, spacing, and support angle of ordinary support structures are difficult to adapt to the location of the wound, which can easily compress the skin around the wound. Moreover, medical staff often need to repeatedly lift and lower the patient's limbs or manually support them, which increases the intensity of nursing care. At the same time, the exudate, waste fluid, and contaminated dressings generated by debridement and irrigation are not easy to collect, which can easily contaminate bed sheets and the operating environment. Summary of the Invention
[0004] The purpose of this invention is to provide an adjustable device for bedside dressing changes for patients with complex, slow-healing wounds, aiming to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable bedside dressing change device for patients with complex, slow-healing wounds includes a flatbed cart. A telescopic rod is fixedly mounted on the middle of the flatbed cart. The telescopic end of the telescopic rod is equipped with a shelf for placing medicines and a medicine collection tray for collecting waste fluid. Two brackets are fixedly mounted on the top of the telescopic end of the telescopic rod. The two brackets are equipped with telescopic parts for adjusting the distance between the two brackets. Pull rods are mounted on the lower sides of the two brackets. Each pull rod is equipped with a stretching component for changing the position of the two brackets.
[0006] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, the telescopic part includes fixed side rods fixedly disposed on both sides of the openings of the two brackets. Each fixed side rod has a limiting groove symmetrically disposed on the inner wall of its cavity. A movable seat is slidably disposed between the limiting grooves. A support rod is fixedly disposed in the middle of the movable seat for connecting the two brackets.
[0007] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, a knob is threadedly connected to the middle of the outer side of the movable seat. The knob is used to adjust the sliding resistance of the movable seat and fix its moving position.
[0008] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, the stretching assembly includes a first movable groove in the middle of the bottom surface of the inner cavity of a fixed side rod provided on one side of a bracket. A lower fixed seat is slidably disposed in the inner cavity of the first movable groove. The lower end of the lower fixed seat is rotatably connected to one end of the pull rod, and the upper end of the lower fixed seat is fixedly connected to the lower surface of the movable seat.
[0009] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, the stretching assembly further includes a second movable groove located in the middle of the bottom surface of the inner cavity of a fixed side rod disposed on the side of another bracket, wherein the diameter of the second movable groove is larger than the diameter of the first movable groove.
[0010] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, a T-shaped slide rod is slidably arranged in the second movable groove, and a triangular fixing seat is fixedly arranged on the lower surface of the T-shaped slide rod, with the middle part of the triangular fixing seat rotatably connected to the other end of the pull rod.
[0011] As a preferred embodiment of the adjustable device for bedside dressing changes for patients with complex, slow-healing wounds according to the present invention, the stretching assembly further includes openings at the top and bottom of one end of the fixed side rod, the length of which is greater than the length of the movable seat, thereby allowing the movable seat to rotate within the openings.
[0012] Compared with the prior art, the beneficial effects of the present invention are: Through the coordinated action of the flatbed cart, telescopic rod, two brackets, telescopic part, fixed side rod, limiting slide, movable seat, support rod and knob, the device can be moved to the side of the hospital bed. The support height of the bracket and the distance between the two brackets can be adjusted according to the height of the hospital bed, the position of the patient's limbs and the distribution of chronic wounds, so as to avoid wound pressure, increase the degree of wound exposure and facilitate medical staff to perform wound cleaning, disinfection and dressing operations.
[0013] Through the coordinated action of the pull rod, the first movable groove, the lower fixed seat, the second movable groove, the T-shaped slide rod, the triangular fixed seat, and the opening groove, the two brackets can maintain linkage support during the adjustment of the spacing or the change of the angle. They can also adapt to different dressing postures of different parts such as the lower leg, heel, and ankle.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] Reference Figure 1-7This is the first embodiment of the present invention. This embodiment provides an adjustable device for bedside dressing changes for patients with complex, slow-healing wounds. It includes a flatbed cart 10, with a telescopic rod 11 fixedly installed in the middle of the flatbed cart 10. The telescopic end of the telescopic rod 11 is provided with a storage platform 12 for placing medicines and a medicine collection tray 13 for collecting waste liquid. Two brackets 14 are fixedly installed at the top of the telescopic end of the telescopic rod 11. The two brackets 14 are provided with telescopic parts 15, which are used to adjust the distance between the two brackets 14. Pull rods 20 are provided on the lower parts of both sides of the two brackets 14. Each pull rod 20 is provided with a stretching component 21, which is used to change the position of the two brackets 14.
[0026] The telescopic rod 11 can be either electric or automatic, as these are existing technologies, and their structural principles will not be elaborated upon here. The flatbed cart 10 is used to support the entire device and facilitates medical staff in moving the device to the side of the bed. The bottom of the flatbed cart 10 can be equipped with universal wheels with locking function to fix the device after it is moved into place, preventing slippage during dressing changes. The telescopic rod 11 is used to adjust the overall height of the bracket 14, the shelf 12, and the dressing tray 13, so that it can adapt to the dressing change needs of patients with different bed heights and different body positions. The shelf 12 can be used to place sterile dressings, dressing instruments, disinfectant bottles, cotton swabs, and medicines, allowing medical staff to access them conveniently when operating at the bedside. The dressing tray 13 is located below or to the side of the bracket 14 and is used to collect waste fluid, exudate, and detached dressings generated during wound cleaning, rinsing, or medication application, reducing the risk of waste fluid dripping onto the bed or floor and causing contamination.
[0027] Two supports 14 are used to support different parts of the patient's limb. The supports 14 can be designed as arc-shaped or semi-circular support structures to conform to the shape of the lower leg, foot, upper limb, etc. In actual use, disposable sterile pads, soft pads, or silicone pads can be placed inside the supports 14 to improve patient comfort and reduce pressure on the skin around the wound. A gap is left between the two supports 14, which corresponds to the location of the patient's wound, allowing the wound to be suspended and exposed, facilitating cleaning, disinfection, medication application, and bandaging by medical staff from around the wound.
[0028] Furthermore, the telescopic part 15 includes fixed side rods 151 fixedly disposed on both sides of the opening of the two brackets 14. Each fixed side rod 151 has a limiting groove 152 symmetrically disposed on the inner wall of its cavity. A movable seat 153 is slidably disposed between the limiting grooves 152. A support rod 154 is fixedly disposed in the middle of the movable seat 153 for connecting the two brackets 14. A knob 155 is threadedly connected to the middle of the outer side of the movable seat 153. The knob 155 is used to adjust the sliding resistance and fix the moving position of the movable seat 153.
[0029] It should be noted that the fixed side rods 151 are arranged on both sides of the bracket 14, allowing the support rods 154 to be connected from the corresponding sides of the two brackets 14 respectively, thereby improving the stability of the two brackets 14 during telescopic adjustment. The limiting groove 152 is used to restrict the movement direction of the movable seat 153, so that the movable seat 153 can only slide along the length direction of the fixed side rods 151, preventing the support rods 154 from swaying or disengaging during adjustment. The support rods 154 are connected to the middle of the movable seat 153. When the movable seat 153 slides along the limiting groove 152, it can simultaneously drive the support rods 154 to extend into or out of the fixed side rods 151, thereby changing the distance between the two brackets 14.
[0030] Specifically, when the patient's wound area is large or when direct pressure on the wound needs to be avoided, medical staff can loosen knob 155 to allow the movable seat 153 to slide along the limiting groove 152, and then pull or push one of the brackets 14 to increase or decrease the distance between the two brackets 14. After the two brackets 14 are adjusted to the appropriate position, knob 155 is tightened, and knob 155 presses against the inner wall of the movable seat 153 or the fixed side rod 151, locking the position of the movable seat 153 and thus maintaining a stable support distance between the two brackets 14. This allows for flexible adjustment of the support position according to the patient's limb length, wound location, and dressing change operation space, avoiding the problem that a traditional single bracket 14 cannot adapt to different wound sites.
[0031] In use, medical staff first push the trolley 10 to the side of the bed and lock the bottom rollers of the trolley 10; then, they adjust the height of the bracket 14 using the telescopic rod 11 to match the height of the patient's limb on the bed; next, they loosen the knob 155 according to the position of the patient's wound to adjust the distance between the two brackets 14 so that the wound is located in the empty area between the two brackets 14 or is easily exposed; after adjustment, they tighten the knob 155 and then place the patient's limb on the two brackets 14. During dressing changes, the shelf 12 is used to place dressing supplies, and the dressing tray 13 is used to collect waste fluid and soiled dressings. Medical staff can complete wound cleaning, disinfection, medication application, and bandaging without frequently moving the patient's limb, improving the convenience and safety of bedside dressing changes.
[0032] Example 2
[0033] Reference Figure 1-7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment includes a stretching assembly 21, comprising a first movable groove 211 located in the center of the bottom surface of the inner cavity of a fixed side rod 151 disposed on the side of one of the brackets 14. A lower fixed seat 212 is slidably disposed within the inner cavity of the first movable groove 211. The lower end of the lower fixed seat 212 is rotatably connected to one end of the pull rod 20, and the upper end of the lower fixed seat 212 is fixedly connected to the lower surface of the movable seat 153. The stretching assembly 21 also includes the bottom surface of the inner cavity of the fixed side rod 151 disposed on the side of the other bracket 14. The second movable groove 213 in the middle of the surface has a diameter larger than that of the first movable groove 211. A T-shaped slide rod 214 is slidably arranged in the second movable groove 213. A triangular fixing seat 215 is fixedly arranged on the lower surface of the T-shaped slide rod 214. The middle part of the triangular fixing seat 215 is rotatably connected to the other end of the pull rod 20. The extension assembly 21 also includes an opening groove 216 opened at the top and bottom of one end of the fixed side rod 151. The length of the opening groove 216 is greater than the length of the movable seat 153, so that the movable seat 153 can rotate in the opening groove 216.
[0034] Specifically, the first movable groove 211 provides clearance for the movement of the lower fixed seat 212. Since the upper end of the lower fixed seat 212 is fixedly connected to the lower surface of the movable seat 153, the lower fixed seat 212 can move synchronously with the movable seat 153 when the movable seat 153 moves along the limiting slide groove 152. The lower end of the lower fixed seat 212 is rotatably connected to one end of the pull rod 20, so that the pull rod 20 can change its angle when the two brackets 14 move or rotate relative to each other, avoiding hard interference between the pull rod 20 and the fixed side rod 151.
[0035] Furthermore, the second movable groove 213 is used to accommodate the T-shaped slide bar 214 and provide a sliding channel for it. Since the diameter of the second movable groove 213 is larger than the diameter of the first movable groove 211, the T-shaped slide bar 214 has a larger range of motion during sliding, which can accommodate the positional changes of the two brackets 14 during stretching, approaching, or flipping. The upper part of the T-shaped slide bar 214 can form a limiting fit with the second movable groove 213 to prevent the T-shaped slide bar 214 from falling out downwards; the triangular fixing seat 215 is fixed to the lower surface of the T-shaped slide bar 214 and is used to rotatably connect with the other end of the pull rod 20, so that the pull rod 20 can form a tensile support between the lower fixing seat 212 and the triangular fixing seat 215.
[0036] Furthermore, the opening slots 216 are located at the top and bottom of one end of the fixed side rod 151. When the movable seat 153 moves to the end area of the fixed side rod 151, the opening slots 216 provide clearance for the partial rotation of the movable seat 153, allowing the movable seat 153 to not only slide along the fixed side rod 151, but also to rotate at a certain angle when the support angle of the bracket 14 needs to be changed. Through this structure, the two brackets 14 can form a horizontal support state, a spacing adjustment state, or an inclined support state according to the patient's limb positioning angle, thereby facilitating the exposure and dressing changes of chronic wounds such as the calf, heel, ankle, or other areas that are inconvenient to directly contact the bed surface.
[0037] When in use, if only the distance between the two brackets 14 needs to be adjusted, the medical staff can release the knob 155 and push or pull the bracket 14. The movable seat 153 moves along the limiting slide groove 152, and the lower fixed seat 212 moves synchronously along the first movable groove 211 with the movable seat 153. At the same time, the pull rod 20 drives the triangular fixed seat 215 and the T-shaped slide rod 214 to slide along the second movable groove 213, thereby making the movement of the two brackets 14 more stable and avoiding the brackets 14 from tilting due to unilateral force.
[0038] When the support angle of the bracket 14 needs to be changed, the medical staff continues to move the movable seat 153 to the corresponding position of the opening slot 216. The opening slot 216 avoids the movable seat 153, allowing the movable seat 153 to rotate at the end of the fixed side rod 151. At the same time, the two ends of the pull rod 20 rotate around the lower fixed seat 212 and the triangular fixed seat 215 respectively, and the T-shaped slide rod 214 produces an adaptive displacement in the second movable slot 213, thereby cooperating with the bracket 14 to form an inclined or unfolded state. After the adjustment is completed, the movable seat 153 is locked by the knob 155, so that the bracket 14 is held at the required support angle and spacing position.
[0039] In summary, during bedside dressing changes, this invention allows for overall device movement via a flatbed cart 10, height adjustment via a telescopic rod 11, placement of dressing supplies via a platform 12, and collection of waste fluid via a dressing tray 13. Two brackets 14 provide segmented support for the patient's limb, and the distance and position between the two brackets 14 are adjustable via a telescopic part 15 and a stretching assembly 21. This device can be adapted to the location of complex, slow-healing wounds, the length of the patient's limb, and the operating angle of medical staff, reducing the need for repeated lifting and manual support of the patient's limb, lowering the risk of contamination and the intensity of nursing labor during dressing changes, and improving the stability and convenience of bedside dressing changes.
