[0022] Please see Figures 1 to 3 The embodiment provides an improved Brown-type frame, which mainly comprises a support body 1, a rapid paving system 2 and a pressure sore prevention buffer system 3.

[0023] Among them, the support body 1 is made of a metal frame and is used as a basic support structure, comprising a thigh support frame 12 and a calf support frame 11. The thigh support frame 12 and the calf support frame 11 are the main frame parts of the Brown-type frame and are respectively used for supporting the thigh and the calf of a patient, and a stable frame structure is formed by fixing the connecting rod, so as to provide reliable traction support; the thigh support frame 12 is usually inclined to adapt to the inclined posture of the thigh after lifting the calf when the patient lies flat, and the calf support frame 11 is horizontally or slightly inclined to support the calf.

[0024] The quick paving system 2 is arranged on the calf support frame 11 and is used for quickly forming and storing a bearing surface. Specifically, the quick paving system 2 comprises a storage bin 21, a clamping bin 25, a support cloth 22 and a locking mechanism 24. It can be understood that the storage bin 21 is a closed or semi-closed structure fixed on the crossbar of the calf support frame 11, and an inner reel 212 is arranged in the storage bin 21 and used for winding and storing the support cloth 22; the clamping bin 25 is a counter connecting component fixed on the crossbar on the other side of the calf support frame 11, and a clamping hole 251 is arranged in the clamping bin 25 and used for receiving and fixing the locking mechanism 24; the support cloth 22 is a flexible fabric with high strength, washing resistance and medical hygiene standard, such as medical canvas or composite cloth, one end of the support cloth 22 is fixed on the reel 212, and the other end of the support cloth 22 is connected to a fixed shaft 23 and used for forming a flat bearing surface after being spread; and the locking mechanism 24 is a mechanical locking device arranged at two ends of the fixed shaft 23, and the locking mechanism 24 is quickly connected and separated from the clamping bin 25 through the clamping cooperation of an inserting piece and the clamping bin 25 and the elastic action of a spring.

[0025] The pressure sore prevention and buffering system 3 is arranged on the upper region of the thigh support frame 12 and is used for providing flexible buffering when the patient's leg slides downward and avoiding local high pressure to cause pressure sores. Specifically, the pressure sore prevention and buffering system 3 comprises a support plate 31, a convex shaft 32, a hinged lug 33 and a reset spring 34. It can be understood that the support plate 31 is a plate-shaped component with a generally rectangular shape, which is usually made of medical plastic or metal, and an arc-shaped groove 311 can be arranged on the surface of the support plate 31 and used for fitting the root of the patient's thigh; the convex shaft 32 is a short shaft fixed on the inclined rod of the thigh support frame 12 and used as a rotating fulcrum; the hinged lug 33 is an ear-shaped connecting piece fixed on the bottom of the support plate 31 and internally provided with a bearing or sleeve and rotatably sleeved on the convex shaft 32; and the reset spring 34 is a spiral spring or a torsion spring, one end of the reset spring 34 is connected to the edge of the support plate 31, and the other end of the reset spring 34 is fixed on a bottom plate 35 and used for providing restoring force after the support plate 31 is pressed and rotated.

[0026] As a preferred scheme of the utility model, the support plate 31 itself can be made of a soft material with certain elasticity, so that the support plate 31 has micro-elastic buffering characteristics while ensuring the supporting strength, thereby improving the basic comfort. More specifically, the support plate 31 is provided with the arc-shaped groove 311, and the shape of the arc-shaped groove 311 is adapted to the curve of the root of the human thigh. In order to further strengthen the pressure sore prevention effect and comfort, the arc-shaped groove 311 can further detachably cover an independent soft pad 312. The soft pad is preferably made of medical silica gel, memory cotton or low-allergy soft foam material, and provides instant and direct buffering, absorbs and disperses local pressure when contacting the human body. The pressure sore prevention function of the utility model is realized by the automatic overturning structure of the support plate 31 to dynamically disperse macro pressure, and the soft pad is additionally arranged to realize micro buffering of the contact interface, so that the two work together to form multi-level and efficient pressure sore prevention and protection.

[0027] Working principle: During the laying stage, the medical staff pulls out the support cloth 22 from the storage bin 21, pulls the fixed shaft 23 to the corresponding position of the clamping bin 25, and quickly forms a flat bearing surface through the clamping locking of the locking mechanism 24 and the clamping bin 25; after use, the locking mechanism 24 is unlocked, and the support cloth 22 is automatically rolled back into the storage bin 21 under the action of the reel 212. In the use stage, when the patient's leg slides down and presses the edge of the support plate 31, the support plate 31 rotates around the convex shaft 32, compresses the reset spring 34, and disperses the local pressure; after the pressure is eliminated, the reset spring 34 pushes the support plate 31 to reset. This scheme significantly improves the operation efficiency and reduces the risk of pressure ulcers through quick laying and buffering mechanism.

[0028] Optionally, in some embodiments, the locking mechanism 24 includes a shell 244, a spring 241, a plug 243, and a limiting plate 242. It can be understood that the shell 244 is a cylindrical or square tubular structure with one end open, usually made of metal or high-strength plastic, used to accommodate and fix the internal components; the spring 241 is a compression spring, which is sleeved on the plug 243 to provide elastic force to keep the plug 243 in the extended state; the plug 243 is a rod-shaped or pin-shaped component, one end of which is fixed to the inner bottom wall of the shell 244, and the other end extends to the opening end, used to insert into the clamping hole 251 of the clamping bin 25 to achieve locking; the limiting plate 242 is a plate-shaped component fixed to the end of the fixed shaft 23, used to limit the compression stroke of the spring 241 and transmit the operating force.

[0029] The locking mechanism 24 achieves locking by cooperating with the pre-set clamping hole 251 of the clamping bin 25 through the plug 243. When the fixed shaft 23 is inserted into the clamping groove of the clamping bin 25, the plug 243 is ejected and clamped into the clamping hole 251 under the elastic force of the spring 241, completing the reliable fixation of the fixed shaft 23 and the clamping bin 25; when unlocking, the plug 243 is pressed to compress the spring 241, so that it is separated from the clamping hole 251, and the fixed shaft 23 can be released. The beneficial effects of this embodiment are that through the cooperation of the mechanical spring 241 and the plug 243, quick and reliable locking and unlocking are achieved, the operation steps are simplified, and the laying efficiency is improved; at the same time, this structure is durable and easy to clean, suitable for medical environment.

[0030] In specific embodiments, the shell 244 of the locking mechanism 24 can be made of medical-grade ABS plastic, the plug 243 is a 304 stainless steel pin, and the spring 241 is a stainless steel compression spring, which ensures that it is not easy to deform during long-term use and meets the medical hygiene standards; during operation, the medical staff only needs to press the two ends of the fixed shaft 23 with one hand to complete the locking, without the need for tools, greatly reducing the preparation time. In addition, this design allows quick replacement and disinfection of the support cloth 22, reducing the risk of cross infection, and improving the overall service life of the equipment through the modular structure.

[0031] Optionally, in some embodiments, a rotating wheel 211 is arranged outside the storage bin 21, which is fixedly connected with the reel 212 for driving the reel 212 to rotate to store the support cloth 22. It can be understood that the rotating wheel 211 is a manually operated wheel, which is usually provided with anti-skid lines or a detachable handle on the outer periphery, and the reel 212 is driven to rotate by manually rotating the rotating wheel 211, so as to roll up the support cloth 22; the rotating wheel 211 can be integrated with a ratchet mechanism to prevent reverse rotation and ensure the stability of storage.

[0032] As an alternative embodiment, a person skilled in the art can also use an electric winding device, for example, a small micro-reduction motor is integrated in the storage bin 21, and the automatic winding and unwinding of the support cloth 22 are controlled by a medical-grade waterproof button.

[0033] In this way, the rotating wheel 211 provides a simple and intuitive storage method, which reduces the time and workload of manually arranging the support cloth 22, and significantly improves the efficiency, especially in large quantities or emergency situations. In a specific embodiment, the rotating wheel 211 can be detachable for easy cleaning and maintenance; a torsional spring can be integrated inside the reel 212 to realize semi-automatic storage, that is, after the lock is released, the support cloth 22 is automatically partially rolled up under the action of the torsional spring, further simplifying the operation. In addition, the design of the rotating wheel 211 allows precise control of the tension of the support cloth 22, ensuring that the bearing surface is flat and comfortable, and improving the patient's experience; by combining the rapid laying system 2, the overall operation time is shortened from several minutes to several seconds, optimizing the clinical workflow.

[0034] Optionally, in some embodiments, a limiting column 36 is arranged in the reset spring 34 for limiting the rotation arc of the support plate 31. The limiting column 36 is fixed vertically on the bottom plate 35, and the axis thereof coincides with the axis of the reset spring 34 and penetrates the inside of the reset spring 34. When the support plate 31 is pressed to rotate, the top end of the limiting column 36 is in contact with the bottom of the support plate 31, limiting the maximum rotation angle (preferably, the rotation angle is not more than 15°) of the support plate 31, preventing the support plate 31 from being excessively flipped; a rubber sleeve can be sleeved on the surface of the limiting column 36 to buffer the impact.

[0035] Through the above scheme, the limiting column 36 ensures that the support plate 31 rotates within a safe range, avoiding damage to the equipment or discomfort of the patient caused by excessive activity; at the same time, it enhances the stability of the buffer system, makes the pressure dispersion more uniform, and effectively prevents pressure sores.

[0036] In specific embodiments, the height of the limiting column 36 can be preset according to the patient's body size, for example, multiple mounting hole positions are provided to adapt to different needs; when the leg slides down, the support plate 31 rotates to the position defined by the limiting column 36, converting the concentrated pressure into surface pressure, reducing local compression; combined with the elasticity of the reset spring 34, the support plate 31 automatically resets after the pressure is removed, maintaining the initial support state. In addition, this structure is simple and reliable, without the need for additional power, reducing manufacturing and maintenance costs, and is suitable for various medical scenarios.

[0037] Optionally, in some embodiments, the support plate 31 is provided with an arc-shaped groove 311, the shape of which is adapted to the curve of the human thigh root. It can be understood that the arc-shaped groove 311 is a groove processed on the upper surface of the support plate 31, the contour of which is designed based on human anatomy data, the depth and width of which match the size of the thigh root, for accommodating and stabilizing the thigh root, reducing sliding and local pressure concentration.

[0038] Through the above scheme, the arc-shaped groove 311 improves the comfort and stability of the support, prevents the leg from sliding on the support plate 31, and further reduces the risk of pressure sores; at the same time, it optimizes the pressure distribution, ensuring more uniform transmission of traction force. In specific embodiments, the depth and width of the arc-shaped groove 311 can be customized based on standard human data, for example, the groove depth is 2-5 centimeters, and the groove width is 10-15 centimeters; in use, the patient's thigh root is embedded in the arc-shaped groove 311, and even slight movement will not disengage the position, combined with the rotating function of the pressure sore prevention buffer system 3, providing dynamic adjustment when the leg slides down. In addition, this design reduces soft tissue shear force, improves the comfort of long-term bedridden patients, and helps the rehabilitation process.

[0039] Optionally, in some embodiments, the arc-shaped groove 311 is also covered with a soft pad. The soft pad is made of medical silicone or memory foam material, adhered or detachably mounted on the inner surface of the arc-shaped groove 311, providing additional cushioning and moisture-wicking and ventilation functions. As an alternative embodiment, those skilled in the art can also use inflatable pads to adapt to individual needs by adjusting air pressure.

[0040] In this way, the soft pad further reduces the contact point pressure, reduces skin problems caused by friction and moisture, and enhances the effect of pressure sore prevention; at the same time, it is easy to replace and clean, maintaining the hygiene standard.

[0041] In specific embodiments, the soft pad can be designed as disposable or sterilizable, for example, covered with an antibacterial fabric; in clinical use, when the support plate 31 rotates, the soft pad deforms to maintain adhesion, dispersing the pressure peak; combined with the contour of the arc-shaped groove 311, it provides a customized support experience, especially beneficial for patients with sensitive skin. In addition, the pad can be integrated with temperature regulation function, such as phase change material, improving patient comfort, and overall optimizing the quality of care.

[0042] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
