Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a special positioning support device for changing dressings for injured patients. Background Technology

[0002] In medical care, when changing dressings for injured patients (especially those with lower limb injuries), it is necessary to maintain a specific body position to fully expose the wound, which facilitates the operation of medical staff, while reducing the patient's pain and avoiding secondary damage to the wound.

[0003] A dressing change support device disclosed in patent CN222788087U, through the setting of a fixing component and a placement mechanism, firstly activates a hydraulic rod, which drives a slider to slide, causing the clamp at one end of the slider to move, thereby fixing the patient's lower leg. The sponge pad can improve the comfort of clamping. Secondly, some medicines and instruments needed for wound cleaning and dressing change can be placed in the drawer. Through the above structure, it is convenient to fix the patient's lower leg to avoid shaking and avoid affecting the dressing change. It also makes it convenient for doctors to access and store the medicines and instruments needed for dressing change, thus improving the efficiency of dressing change.

[0004] The device has poor angle stability. During dressing changes, if it is touched by a slight external force, the support angle is prone to shift, which not only affects the smooth progress of the dressing change, but may also cause stress on the patient's wound, causing pain or even secondary injury. Utility Model Content

[0005] The purpose of this invention is to provide a special positioning support device for changing dressings for injured patients, which solves the problems of cumbersome adjustment operation, low adjustment accuracy, poor fixation stability and insufficient comfort of existing support devices.

[0006] To achieve the above objectives, this utility model provides a special positioning support device for dressing changes of injured patients, including a thigh support plate, a calf support plate, and an angle adjustment component. The thigh support plate and the calf support plate are connected by a rotating mechanism. The rotating mechanism includes a rotating block fixedly connected to the end of the calf support plate, and the rotating block is rotatably connected to the thigh support plate through a rotating shaft. The angle adjustment component is used to adjust the angle between the thigh support plate and the calf support plate to adapt to the positioning needs of different patients. The angle adjustment component includes a fixing block, which is fixedly connected to the bottom of the thigh support plate. A second screw is threaded through the inside of the fixing block. An adjustment plate is rotatably connected to the end face of the second screw. The adjustment plate is slidably connected to the bottom of the thigh support plate. An adjustment connecting rod is hinged between the adjustment plate and the rotating block. The second screw has a second knob fixedly connected to its other end. The second knob and the adjusting plate are located on opposite sides of the second screw. By rotating the second knob, the second screw can be moved axially within the fixed block, thereby pushing the adjusting plate to slide at the bottom of the thigh support plate. The adjusting plate, through the adjusting linkage, drives the rotating block to rotate around the axis, ultimately adjusting the angle between the thigh support plate and the calf support plate. The operation is convenient, and the angle can be precisely adjusted by controlling the number of rotations of the second knob. The second screw's thread lead angle is smaller than the equivalent friction angle, creating a self-locking structure between the second screw and the fixed block. Once adjusted to the desired angle, stable positioning of the second screw is achieved without additional fixing components, effectively preventing support angle shifts caused by external forces after angle adjustment and improving the device's stability. Simultaneously, the outer side of the second screw is coated with grease, reducing frictional resistance between the second screw and the fixed block, making the rotation and movement of the second screw smoother, reducing the force required for adjustment, and improving ease of use. To enhance patient comfort, the upper surfaces of both the thigh support plate and the calf support plate are covered with elastic cushioning pads. These pads are made of medical-grade silicone, which has excellent softness and elasticity. They can effectively distribute pressure on the patient's limbs and prevent poor blood circulation caused by local pressure. At the same time, medical-grade silicone has good biocompatibility and antibacterial properties, which can reduce the risk of skin allergies and infections in patients. The thigh support plate is equipped with detachable restraint straps on both sides, and the ends of the restraint straps are equipped with Velcro. The restraint straps can fix the patient's thigh to the thigh support plate to prevent the patient's limb from moving involuntarily during dressing changes, which would cause stress on the wound and further improve the safety and stability of the device.

[0007] 1. In this utility model, the rotating mechanism achieves a flexible and stable rotating connection between the thigh support plate and the calf support plate through the cooperation of the rotating block and the rotating shaft. This component can provide a reliable rotating basis for adjusting the body position angle, ensuring that the calf support plate remains stable during the angle change process, avoiding discomfort to the patient's limb due to rotation jamming or instability. At the same time, the rigid connection design of the rotating shaft can withstand the weight of the patient's limb, preventing the connection from loosening after long-term use, and further improving the support stability and service life of the device.

[0008] 2. In this utility model, the angle adjustment component achieves angle adjustment by rotating the second knob through the coordinated transmission of the fixed block, the second screw, the adjustment plate, and the adjustment connecting rod, greatly improving the convenience of operation. It can also achieve precise angle adjustment by controlling the number of rotations of the knob, taking advantage of the thread transmission characteristics of the second screw, to adapt to the wound position and limb shape requirements of different patients. In addition, the self-locking structure of the second screw can automatically lock the angle after adjustment, effectively avoiding angle deviation caused by external force, and ensuring the safe and stable operation of dressing change.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] Please see Figure 1-5As shown, this embodiment of a positioning support device for wounded patients undergoing dressing changes includes a thigh support plate 1 and a calf support plate 4. A calf adjustment component 2 is disposed between the thigh support plate 1 and the calf support plate 4. An angle adjustment component 3 is disposed at the bottom of the thigh support plate 1. A support shell 9 is fixedly connected to the bottom of the thigh support plate 1. A telescopic support rod 7 is fixedly connected to the bottom of the support shell 9. A base plate 8 is fixedly connected to the bottom of the telescopic support rod 7. Anti-slip pads 10 are fixedly connected to the four corners of the bottom of the base plate 8. An adjustment block 21 is fixedly connected to the side plate of the calf support plate 4. A limit rod 22 is slidably connected inside the adjustment block 21. A rotating block 23 is fixedly connected to the top of the limit rod 22. The rotating block 23 is hinged to the front bottom of the thigh support plate 1. A first screw 24 is rotatably connected to the bottom of the rotating block 23. The first screw 24 is screwed through the interior of the adjustment block 21. A first knob 25 is fixedly connected to the bottom of the first screw 24. The lead angle of the first screw 24 is less than the equivalent friction angle, and the outer side of the first screw 24 is coated with grease. A first pad 5 is fixedly connected to the top of the thigh support plate 1, and a second pad 6 is fixedly connected to the outer side of the calf support plate 4. Both the first pad 5 and the second pad 6 are arc-shaped sponge pads. A rotating block 23 is fixed to the end of the calf support plate 4, and a rotating shaft passes through the rotating block 23 and the thigh support plate 1, allowing the rotating block 23 to rotate flexibly around the rotating shaft, thereby causing the calf support plate 4 to deflect at an angle around the rotating shaft. This structure provides basic rotational support for adjusting the angle between the thigh support plate 1 and the calf support plate 4, ensuring that the calf support plate 4 can achieve stable angle changes according to the patient's position requirements. Simultaneously, the rigid connection of the rotating shaft ensures the stability of the connection during rotation, preventing loosening due to limb weight.

[0018] Please see Figure 1-5As shown, the angle adjustment component 3 in this embodiment includes a fixing block 33, which is fixedly connected to the bottom of the thigh support plate 1. A second screw 34 is screwed through the inside of the fixing block 33. An adjusting plate 31 is rotatably connected to the end face of the second screw 34. The adjusting plate 31 is slidably connected to the bottom of the thigh support plate 1. An adjusting connecting rod 32 is hinged between the adjusting plate 31 and the rotating block 23. A second knob 35 is fixedly connected to the other end of the second screw 34. The second knob 35 and the adjusting plate 31 are located on opposite sides of the second screw 34. The thread lead angle of the second screw 34 is smaller than the equivalent friction angle, and the outer side of the second screw 34 is coated with grease. The fixing block 33 is fixed to the bottom of the thigh support plate 1, providing fixed support for the second screw 34. When the second knob 35 is rotated, the second screw 34 moves axially under the action of the internal thread of the fixing block 33, pushing the adjusting plate 31, which is rotatably connected to it, to slide along the bottom of the thigh support plate 1. During the sliding process of the adjusting plate 31, the adjusting connecting rod 32, which is hinged, drives the rotating block 23 to rotate around the axis, converting the linear motion of the adjusting plate 31 into the rotational motion of the rotating block 23, and finally realizing the angle adjustment of the calf support plate 4. At the same time, since the thread lead angle of the second screw 34 is less than the equivalent friction angle, a self-locking structure is formed. After the target angle is adjusted, the second screw 34 cannot move on its own, keeping the adjusting plate 31, the adjusting connecting rod 32 and the rotating block 23 in a fixed position, thereby locking the angle between the thigh support plate 1 and the calf support plate 4. In addition, the grease on the outside of the second screw 34 can reduce the frictional resistance during the transmission process, ensuring smooth and effortless adjustment operation.

[0019] Working Principle: The device achieves body position support and angle adjustment through the coordinated action of a rotating mechanism and an angle adjustment component 3. The rotating mechanism is centered on a rotating block 23 fixed to the end of the calf support plate 4. The rotating block 23 is rotatably connected to the thigh support plate 1 via a rotating shaft, providing basic rotational support for changes in the angle between the thigh support plate 1 and the calf support plate 4. When the body position angle needs adjustment, medical personnel rotate the second knob 35. The second knob 35 drives the second screw 34 to move axially within the fixed block 33 fixed to the bottom of the thigh support plate 1. Since the end face of the second screw 34 is rotatably connected to the adjustment plate 31, the second screw 34 pushes the adjustment plate 31 to slide along the bottom of the thigh support plate 1. The adjustment plate 31, through a hinged adjustment rod 32, drives the rotating block 23 to rotate around the rotating shaft, which in turn drives the calf support plate 4. The leg support plate 4 rotates synchronously, achieving precise adjustment of the angle between the thigh support plate 1 and the calf support plate 4. When adjusted to the target angle suitable for the patient's wound dressing change, because the thread lead angle of the second screw 34 is less than the equivalent friction angle, the second screw 34 and the fixing block 33 form a self-locking structure, and the second screw 34 cannot move on its own, keeping the adjusting plate 31, adjusting connecting rod 32 and rotating block 23 in a fixed position, thereby stably locking the angle between the thigh support plate 1 and the calf support plate 4. At the same time, the grease coated on the outside of the second screw 34 can reduce transmission friction and ensure smooth adjustment operation. Combined with the elastic buffer pads on the thigh support plate 1 and the calf support plate 4 and the restraint straps on both sides of the thigh support plate 1, it not only ensures the patient's comfort but also prevents limb movement, providing stable and safe positional support for the dressing change operation. After each use, medical staff should promptly clean and disinfect the device, wiping the surfaces of components such as the thigh support plate 1, calf support plate 4, and angle adjustment assembly 3 with medical disinfectant, paying particular attention to the elastic cushioning pads on the upper surfaces of the thigh support plate 1 and calf support plate 4 to ensure cleanliness and prevent cross-infection. Regularly check the application of grease on the outer side of the second screw 34; if the grease is reduced or deteriorated, replenish or replace it promptly to ensure smooth rotation of the second screw 34. Regularly check the connections of each component, such as the connection between the fixing block 33 and the thigh support plate 1, the hinges between the adjusting rod 32 and the adjusting plate 31 and rotating block 23, and the integrity of the restraint straps on both sides of the thigh support plate 1. If any components are found to be loose, damaged, or severely worn, repair or replace them promptly to ensure normal device operation.
