Description

Technical Field

[0001] This utility model relates to the field of medical device technology for burn care, specifically targeting the lower limb rehabilitation care scenario for burn patients. It focuses on the needs for body position fixation, wound protection, nursing convenience, and infection control during the lower limb elevation process. It belongs to the category of structural optimization and functional enhancement of medical rehabilitation nursing equipment and can be widely used in hospital burn departments, rehabilitation departments, and home burn rehabilitation care scenarios. It is suitable for the elevation care needs of patients of different body types and various burn wounds. Background Technology

[0002] In current burn lower limb elevation care, traditional elevation devices (such as simple supports or ordinary nursing beds with added elevation pads) have several core drawbacks, seriously affecting nursing outcomes and patient experience. These include: Traditional elevation devices are mostly single, fixed structures, lacking support designs adapted to the physiological curves of the lower limbs. When the patient's lower limbs are placed, local pressure can easily occur (such as on the back of the calf or in burn areas of the ankle), leading to obstructed blood circulation to the wound, prolonged edema resolution time, and even secondary wound damage (such as ruptured blisters or wound deepening). Furthermore, some elevation frames lack reliable bed-frame connection structures, making it difficult for patients to move even slightly (such as turning over or adjusting posture). 1. When in a confined space, the main bed and bed frame are prone to sliding relative to each other, requiring repeated adjustments to the patient's position, increasing patient discomfort and the workload of medical staff; 2. Traditional elevated frames are mostly made of hard plastic or metal, without a dedicated pressure-reducing and protective structure. Prolonged support can easily lead to numbness and muscle stiffness in the patient's limbs (especially the knee and hip joints); and the edges of the frame are not treated with flexibility, which can easily scratch the fragile skin around the burn wound; 3. Burn care requires frequent use of disinfection tools and dressings, and disposal of waste fluids (such as residual dressing fluids and disinfectants), but traditional equipment does not have a dedicated storage structure, and tools are placed randomly, which can easily cause cross-contamination. Waste fluids are easily spilled during the pouring process, increasing the risk of hospital-acquired infections.

[0003] Therefore, a lower limb elevation frame for burn patients needs to be designed to solve the problems mentioned above. Utility Model Content

[0004] To address the problems of unreliable body positioning, easy pressure and friction on the wound, inconvenient nursing procedures, and difficulty in infection control associated with traditional burn lower limb elevation devices, this utility model designs a burn lower limb elevation frame. By optimizing the bed connection structure, the shape of the elevation frame, protective components, and storage functions, it achieves stable fixation of the burn lower limb, safe protection of the wound, convenient nursing procedures, and controllable infection risks. It meets the clinical nursing needs of burn departments for practicality, safety, and professionalism of equipment, and improves the patient nursing experience and rehabilitation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A burn lower limb elevation frame is provided. This burn lower limb elevation frame is composed of a bed frame, main bed body, elevation base frame, elevation bed board, elevation frame body, side board, back board, limiting protrusion, tenon joint, storage shelf and universal casters. Each component is designed around the core objectives of "fixed and reliable, wound protection and nursing care fit".

[0007] Furthermore, the bed frame serves as the main support frame for the equipment. The top supports the main bed body, while the bottom and the raised base are equipped with universal casters with braking function. When unlocked, the equipment can be flexibly moved (adapting to the movement needs of multiple scenarios such as wards and dressing rooms). When locked, the equipment is ensured to be stable, avoiding displacement caused by nursing operations or slight movements of the patient.

[0008] Furthermore, the main bed provides support for the patient's upper body and proximal lower limbs, and a backrest is fixedly installed on the side away from the raised bed board to provide support for the patient's back; the raised bed board is connected to one side of the main bed, and the top supports the raised frame, forming a basic platform for lower limb elevation. The two work together to construct a complete nursing space of "upper body support + lower limb elevation".

[0009] Furthermore, a limiting protrusion is provided on one side of the main bed body on the bed frame, and a limiting groove is provided at the corresponding position on the main bed body. The surface of the limiting protrusion is covered with a silicone elastic anti-slip layer, and a guide slope is provided on the inner wall of the groove. During installation, the guide slope guides the protrusion to be accurately inserted into the groove, and the elastic anti-slip layer fills the gap and generates friction to prevent the main bed body and the bed frame from sliding relative to each other, thus ensuring the positional stability of the lower limbs after placement.

[0010] Furthermore, the bed frame and the main bed body are provided with interlocking tenons and interlocking slots. After the interlocking tenon is inserted into the slot, the anti-detachment pin passes through the pin hole of the tenon and the bed frame to restrict axial movement. The elastic buckle on the side of the tenon is inserted into the groove of the inner wall of the slot to prevent radial loosening. The double fixing structure strengthens the connection strength between the main bed body and the bed frame and avoids bed shaking caused by the patient turning over or nursing operations.

[0011] Furthermore, the elevated frame is fixed to the top of the elevated bed board, and its surface is designed with an ergonomic curved surface that conforms to the physiological curve of the lower limbs. It adopts a three-section split structure (thigh support section, calf support section, and foot support section), which can be specifically adapted to the elevation needs of different lower limb parts (such as adjusting the angle of the thigh support section when the front of the thigh is burned, and optimizing the position of the foot support section when the ankle joint is burned). The curved surface edges are equipped with flexible edging to prevent the frame edges from scratching the fragile skin around the wound and reduce the risk of friction injury.

[0012] Furthermore, the surface of the elevated frame is covered with a pressure-reducing protective pad made of medical memory foam, with pressure-dispersing airbags embedded inside. The air pressure of the airbags can be adjusted by the inflation valves on the side of the bed frame. According to the patient's weight and the location of the wound, medical staff can precisely control the airbag pressure, dynamically disperse the local pressure on the limb, keep the pressure on the wound within a safe range, avoid obstruction of blood circulation in the wound, and reduce the risk of secondary injury such as blister rupture and wound deepening.

[0013] Furthermore, the longer sides of the top of the bed frame are connected to the side panels via damping hinges, which can be rotated around the hinges to adjust the angle. When unfolded, they surround the sides of the bed to prevent the patient's limbs from slipping and provide lateral support for the patient. The damping structure ensures that the side panels can be rotated smoothly, avoiding sudden rotation that could pinch the patient, and adapting to the protection needs of patients of different body types.

[0014] Furthermore, the raised bed board features flip-up shelves on both sides. When flipped open, these shelves can hold nursing tools and have partitioned sections: the sterilization tool area is covered with an antibacterial silicone mat for placing tweezers, scissors, and other sterilization instruments to prevent contamination; the dressing area has a breathable mesh bag to keep dressings dry and prevent them from getting damp and deteriorating; and the waste liquid storage area is a recessed area with a sealed lid to collect residual dressing fluids and disinfectants, preventing waste liquids from spilling and polluting the environment. When not in use, the shelves can be flipped up to fit against the raised bed board side without taking up extra space.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the design of a burn lower limb elevation frame, achieves the following effects: 1. Through the dual connection structure of the limiting protrusion (with an elastic anti-slip layer) and the limiting groove (with a guide slope), and the insertion tenon (with an anti-detachment pin and elastic buckle) and the insertion slot, the probability of relative sliding between the main bed and the bed frame is reduced, significantly lowering the risk of lower limb displacement; the guide slope design improves the accuracy of the protrusion and tenon insertion, enhances installation convenience, and reduces adjustment time for medical staff; 2. The ergonomic curved surface and three-section split structure of the elevation frame precisely conform to the physiological curves of the thigh, calf, and foot, and, in conjunction with medical memory foam pressure-reducing protective pads and pressure-dispersing airbags, the limb... 1. Improved uniformity of body pressure distribution reduces local pressure on the wound to a safe range, shortens edema resolution time, and reduces the risk of secondary wound damage; 2. The flexible edging of the raised frame edges and the medical memory foam material of the pressure-reducing protective pads improve the comfort of limb contact with the frame and prolong the patient's tolerance time; the pressure-dispersing airbag dynamically adjusts the air pressure to suit patients of different weights, reducing the incidence of muscle stiffness and limb numbness; 3. The partitioned shelves (disinfection tool area, dressing placement area, waste liquid temporary storage area) achieve 100% classification and storage rate of nursing tools, reducing the rate of bacterial cross-contamination; antibacterial silicone pads and breathable mesh bags further reduce the risk of infection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0023] Example 1

[0024] Please see Figure 1 This embodiment provides a burn lower limb elevation frame, which mainly consists of a bed frame 1, a main bed body 2, an elevation base frame 3, an elevation bed board 4, and an elevation frame body 5. The elevation frame body 5 is installed on top of the elevation bed board 4 and is used to support the patient's burn lower limb.

[0025] Example 2

[0026] Please see Figure 1 Based on embodiment 1, this embodiment further limits the installation of side plates 6 on both sides of the longer side of the top of the bed frame 1 via damping hinges. The side plates 6 can be rotated around the damping hinges, which can not only provide protection during patient use and prevent the patient from slipping off the sides of the bed frame 1, but also adjust the opening and closing state according to actual needs, making it convenient for medical staff to perform nursing operations on the patient.

[0027] Example 3

[0028] Please see Figure 1 Based on Example 1, this embodiment further specifies that a backrest 7 is fixedly installed on the side of the main bed 2 away from the raised bed board 4. The backrest 7 can provide support for the patient's back, so that the patient can maintain a more comfortable position and reduce back pressure when using the raised bed frame.

[0029] Example 4

[0030] Please see Figure 3 Based on embodiment 1, this embodiment further limits the bed frame 1 to one side of the main bed body 2, with a limiting protrusion 8 and a tenon 9 corresponding to it. At the same time, on the side of the main bed body 2 located on the raised bed board 4, a limiting groove 10 and a tenon 9 corresponding to the limiting protrusion 8 and the tenon 9 are respectively provided. By inserting the limiting protrusion 8 into the limiting groove 10 and the tenon 9 into the tenon 11, the relative position between the main bed body 2 and the bed frame 1 can be effectively limited, preventing them from shifting.

[0031] Example 5

[0032] Please see Figure 1 Based on embodiment 1, this embodiment further specifies that the bottom of the bed frame 1 and the raised base frame 3 are also equipped with universal casters with braking function. The universal casters make it easy for medical staff to push the entire raised frame to adjust its position according to the needs of diagnosis and treatment; while the braking function can fix the raised frame after it has been moved to the target position, preventing the raised frame from moving on its own during use and ensuring the safety of the patient.

[0033] Example 6

[0034] Please see Figure 3 Based on embodiment 4, this embodiment further specifies that an elastic anti-slip layer made of silicone material is provided on the surface of the limiting protrusion 8. When the limiting protrusion 8 is inserted into the limiting groove 10, the elastic anti-slip layer will deform due to compression, filling the gap between the limiting protrusion 8 and the limiting groove 10. At the same time, a large frictional force will be generated between the elastic anti-slip layer and the inner wall of the limiting groove 10, thereby effectively enhancing the tightness of the connection between the two.

[0035] Meanwhile, a guide slope is provided on the inner wall of the limiting groove 10. This guide slope guides the limiting protrusion 8 during insertion into the limiting groove 10, allowing the limiting protrusion 8 to be inserted into the limiting groove 10 more accurately and smoothly, avoiding insertion difficulties due to misalignment. Through the above structural design, relative sliding between the main bed body 2 and the bed frame 1 can be effectively prevented, further ensuring the stability of the burned lower limb on the elevated frame and reducing secondary damage to the burn wound caused by limb movement.

[0036] Example 7

[0037] Please see Figure 1 as well as Figure 3 Based on embodiment 4, this embodiment further specifies that an anti-detachment pin is provided between the tenon 9 and the insertion slot 11. When the tenon 9 is inserted into the insertion slot 11, the anti-detachment pin is inserted into the corresponding pin hole on the bed frame 1. The anti-detachment pin can restrict the axial movement of the tenon 9 and prevent the tenon 9 from coming out of the insertion slot 11 along the axial direction.

[0038] Meanwhile, an elastic buckle is provided on the side of the tenon 9. Correspondingly, a groove adapted to the elastic buckle is provided on the inner wall of the insertion slot 11. When the tenon 9 is inserted into the insertion slot 11, the elastic buckle will be compressed by the inner wall of the insertion slot 11. After the tenon 9 is inserted into place, the elastic buckle will automatically spring open and lock into the groove, thereby restricting the radial movement of the tenon 9 and preventing the tenon 9 from radially loosening in the insertion slot 11. Through the dual limiting effect of the anti-loosening pin and the elastic buckle, the connection strength between the main bed body 2 and the bed frame 1 can be significantly strengthened, ensuring the stability of the overall structure of the raised frame.

[0039] Example 8

[0040] Please see Figure 1 Based on Embodiment 1, this embodiment further specifies that the surface of the elevation frame 5 adopts an ergonomic curved surface design, and the overall structure is a three-section split structure, namely the thigh support section, the calf support section, and the foot support section. This structural design can conform to the physiological curve of the human lower limb, so that the patient's thigh, calf, and foot can be evenly supported, avoiding excessive local pressure and reducing patient discomfort. In addition, a flexible edging is provided at the edge of the curved surface of the elevation frame 5. The flexible edging is made of a soft and smooth material, which can effectively prevent the sharp edges of the elevation frame 5 from scratching the patient's burn wound, and at the same time reduce the friction between the limb and the edge of the elevation frame 5, reducing the risk of wound damage caused by friction, and further improving the patient's comfort and safety.

[0041] Example 9

[0042] Please see Figure 2 This embodiment, based on embodiment 8, further specifies that a pressure-reducing protective pad is laid on the surface of the elevated frame 5. This pressure-reducing protective pad is made of medical memory foam, which has good elasticity and shape-forming properties, and can conform to the shape of the patient's lower limbs, evenly distributing the pressure generated by the weight of the limbs and avoiding local pressure concentration that could compress the burn wound. Simultaneously, a pressure-dispersing airbag is embedded inside the pressure-reducing protective pad, and an inflation valve is provided on the side of the bed frame 1. The inflation valve is connected to the pressure-dispersing airbag, allowing medical staff to adjust the air pressure by inflating or deflating the airbag according to the patient's actual condition and wound recovery needs. Dynamically adjusting the air pressure further optimizes the pressure dispersion effect, making the pressure on different parts of the limbs more even, thereby minimizing the risk of damage to the burn wound due to pressure.

[0043] Example 10

[0044] Please see Figure 1Based on Embodiment 1, this embodiment further specifies that flip-up shelves 12 are provided on both the left and right sides of the raised bed board 4. The shelves 12 can be flipped around the connection between them and the raised bed board 4. They can be unfolded when in use and flipped up when not in use to save space. The surface of the shelves 12 is provided with partitions, namely a disinfection tool area, a dressing placement area, and a waste liquid storage area. The disinfection tool area is covered with an antibacterial silicone pad, which can inhibit bacterial growth and keep the disinfection tool area clean and hygienic, providing a clean storage environment for disinfection tools. The dressing placement area is provided with a breathable mesh bag, which has good breathability and can prevent the dressing from growing bacteria due to moisture during storage, ensuring that the dressing is dry and clean. The waste liquid storage area is a groove with a sealed cover. Waste liquid generated by medical staff during the care of patients' wounds can be temporarily stored in this groove. The sealed cover can prevent the waste liquid from evaporating and producing odors, and at the same time avoid the waste liquid leakage and pollution, effectively reducing the risk of hospital-acquired infections.

[0045] Workflow: When using this burn lower limb elevation frame, first align the limiting protrusion 8 on the bed frame 1 with the limiting groove 10 on the main bed body 2. Guide the limiting protrusion 8 precisely into place using the guide slope on the inner wall of the limiting groove 10. At this time, the silicone elastic anti-slip layer on the surface of the limiting protrusion 8 fills the gap and generates friction. Simultaneously, insert the tenon 9 of the bed frame 1 into the insertion slot 11 of the main bed body 2. After insertion, insert the anti-detachment pin into the pin hole of the tenon 9 and the bed frame 1 to restrict axial movement. Simultaneously, the elastic buckle on the side of the tenon 9 automatically engages with the groove on the inner wall of the insertion slot 11 to prevent radial loosening, completing the stable assembly of the main bed body 2 and the bed frame 1. Then, flip the side panels 6 on both sides of the longer side of the top of the bed frame 1, connected by damping hinges, and adjust them to a suitable protection angle. Unfold the left and right sides of the elevation bed board 4. Check the surface of the flip-up shelf 12 to ensure that the disinfection tool area (with antibacterial silicone pad), dressing placement area (with breathable mesh bag), and waste liquid storage area (with sealed cover groove) are intact and that the partition function is normal. Check the stability of the three-section structure (thigh support section, calf support section, and foot support section) of the raised frame 5 and whether the flexible edging is damaged. Then, inflate the pressure-dispersing airbag in the pressure-reducing protective pad on the surface of the raised frame 5 through the inflation valve on the side of the bed frame 1. Adjust the air pressure to a suitable pressure value according to clinical needs to ensure that the pressure-reducing protective pad made of medical memory foam can conform to the limb curve. Push the bed frame 1 or the raised base 3 and use the universal casters with brake function at the bottom to move the equipment to the target position. Step on the brake to fix the universal casters and complete the equipment assembly and debugging.

[0046] When using the device, assist the patient to lie on the main bed 2, with their back supported by the backrest 7 fixed to the main bed 2. Place the burned lower limb on the raised frame 5 at the top of the raised bed board 4, ensuring that the thigh, calf, and foot correspond to the thigh support section, calf support section, and foot support section of the raised frame 5, respectively. Ensure that the limb conforms to the ergonomic curved surface of the raised frame 5, avoiding contact between the wound and any area other than the flexible edging of the raised frame 5. Medical staff can retrieve sterilized instruments from the sterilization tool area of ​​the shelf 12 and take dressings from the dressing placement area to perform nursing procedures on the patient's burn wound. Waste liquid generated during the nursing process should be promptly poured into the waste liquid storage area groove of the shelf 12 and covered with a sealed cap to prevent contamination. To prevent the spread of contamination; if it is necessary to adjust the patient's position or the equipment position during the nursing process, the universal caster brake can be released to move the equipment, and the brake can be fixed again after adjustment. If necessary, the side plate 6 can be flipped over for easy operation. After the patient has finished using the equipment, first clean up the waste dressings, waste liquids, etc. in the shelf 12, and clean and disinfect the antibacterial silicone pad in the disinfection tool area and the breathable mesh bag in the dressing placement area; release the pressure through the inflation valve to disperse the gas in the airbag, and smooth the pressure relief protective pad on the surface of the raised frame 5; flip and fold up the shelf 12 and the side plate 6, and check whether each component (such as the limit protrusion 8, the tenon 9, the universal caster, etc.) is intact. If there is any damage, repair or replace it in time to ensure that the equipment can be used normally next time.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
