Abstract
Description
Technical Field
[0001] This utility model relates to the field of headboard elevation, and in particular to a headboard elevation angle alarm device. Background Technology
[0002] The widespread use of mechanical ventilation has significantly increased the incidence of ventilator-associated pneumonia (VAP), prolonging ventilation time, increasing complications and mortality. Since artificial airways and sedative drugs weaken airway protection, gastric reflux and aspiration have become important causes of VAP. Studies have shown that elevating the head of the bed by 30°–45° can effectively reduce reflux and aspiration. Therefore, domestic and international guidelines recommend it as a key measure for VAP prevention (except for contraindications).
[0003] However, in clinical practice, due to factors such as a lack of measuring tools and insufficient supervision, nurses have poor judgment on the angle of headboard elevation, and the elevation angle may not reach the predetermined range, affecting the prevention effect of VAP. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a headboard elevation angle alarm, which improves the accuracy and convenience of headboard angle adjustment.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A bed head elevation angle alarm includes:
[0007] A mounting support plate for connection support is provided. Connecting blocks are fixedly connected to both sides of the top of the mounting support plate. An angle display frame is fixedly connected to the top of the connecting blocks. An angle measuring transparent plate is fixedly connected to both sides of the inside of the angle display frame. Multiple mounting pieces are fixedly connected to the outer circumference of the mounting support plate. A gravity adjustment ring is provided on the inner side of the angle display frame. Indicator blocks are fixedly connected to both sides of the gravity adjustment ring. The indicator blocks penetrate into the inside of the angle display frame. A counterweight arc block is fixedly connected to the lower inner side of the gravity adjustment ring. A flipping traction component is installed on both sides of the gravity adjustment ring to achieve accurate angle adjustment of height.
[0008] An illumination ring light is used to install the top lighting of the support plate. The illumination ring light is externally fixedly connected to the inside of the connecting block.

[0009] Furthermore, the color display device includes two red diffuse reflective plates fixedly connected to the bottom sides of the angle display frame, and the top of the red diffuse reflective plates is attached to the bottom of the angle measuring transparent plate. The area of the red diffuse reflective plates is equal to the area of the rotating roller at 30° to 45°.
[0010] Furthermore, the flipping traction assembly includes multiple fixed seats located on both sides of the gravity adjustment ring. A fitting rotating roller is rotatably connected to the inner side of the fixed seat. A limiting roller is fixedly connected to the outer side of the fitting rotating roller. The outer side of the fitting rotating roller is fitted to the inner side of the angle display frame. The outer side of the limiting roller is inserted into the arc groove on the inner side of the angle display frame.
[0011] Furthermore, a limiting rotating ring is fixedly connected to the top of the gravity adjustment ring, and the lower outer part of the limiting rotating ring is rotatably connected to the top of the angle display frame.

[0016] 1. In this utility model, the counterweight arc block generates a downward flipping force on the gravity adjustment ring, while the indicator block initially indicates 0°. As the head of the bed flips, the angle display frame flips accordingly, and the angle indicated by the indicator block changes, thereby monitoring the change in the lifting height angle and improving the accuracy of the device's adjustment.
[0017] 2. In this utility model, the illumination conditions are generated by the lighting ring lamp, which reflects the light onto the red diffuse reflector plate. Furthermore, the light is softened by its own diffuse reflection, which improves the convenience of observation by the device and further facilitates the adjustment of the headboard angle.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a bed head elevation angle alarm, comprising: a mounting support plate 1 for connection and support, as shown in the figure. Figure 4A connecting block 14 is fixedly connected to both sides of the top of the mounting support plate 1. An angle display frame 2 is fixedly connected to the top of the connecting block 14. An angle measuring transparent plate 9 is fixedly connected to both sides of the inside of the angle display frame 2. Multiple mounting pieces 8 are fixedly connected to the outer circumference of the mounting support plate 1. A gravity adjustment ring 5 is provided on the inner side of the angle display frame 2. An indicator block 12 is fixedly connected to both sides of the gravity adjustment ring 5 and penetrates into the inside of the angle display frame 2. A counterweight arc block 7 is fixedly connected to the lower inside of the gravity adjustment ring 5. A flipping traction component is installed on both sides of the gravity adjustment ring 5 to achieve accurate height adjustment. The flipping traction assembly includes multiple fixed seats 10 located on both sides of the gravity adjustment ring 5. A fitting rotating roller 15 is rotatably connected to the inner side of the fixed seat 10. A limiting roller 11 is fixedly connected to the outer side of the fitting rotating roller 15. The outer side of the fitting rotating roller 15 is fitted to the inner side of the angle display frame 2. The outer side of the limiting roller 11 is inserted into the arc groove on the inner side of the angle display frame 2. A limiting rotating ring 3 is fixedly connected to the top of the gravity adjustment ring 5. The lower outer side of the limiting rotating ring 3 is rotatably connected to the top of the angle display frame 2. Transparent observation plates 4 are fixedly connected to both sides of the top of the angle display frame 2 to enable internal observation while providing protection.
[0028] With pre-set threaded mounting holes at the head of the bed, the positioning holes of multiple mounting pieces 8 are aligned with the reserved holes and then secured with bolts. The counterweight arc block 7 always applies a vertically downward force to the gravity adjustment ring 5. In the initial state, the indicator blocks 12 on both sides point to the 0° reference position of the angle display ring 19, and its four quadrant scales are all distributed in 90° intervals. When adjusting the head of the bed, as the bed angle is rotated, the gravity of the counterweight arc block 7 keeps the gravity adjustment ring 5 at the vertical reference. At this time, the angle display frame 2 rotates synchronously, and the direction of the indicator block 12 changes accordingly, accurately reflecting the current lifting angle. This structure achieves precise adjustment and real-time monitoring of the head of the bed lifting height through the synergistic effect of gravity reference and mechanical linkage, significantly improving the accuracy and reliability of angle control.
[0029] Reference Figure 4 , Figure 5 and Figure 6The lighting ring lamp 13 is used to install the top lighting of the support plate 1. The lighting ring lamp 13 is fixedly connected to the inside of the connecting block 14. Color display devices are installed on both sides of the bottom end of the angle display frame 2 to achieve clear angle display for height adjustment. The color display devices include 17 located on both sides of the bottom end of the angle display frame 2. Red diffuse reflective plates 18 are fixedly connected to both sides of the inside of 17. The top ends of 17 and red diffuse reflective plates 18 are attached to the bottom end of the protractor 9. The area of the red diffuse reflective plate 18 is equal to the area of the 30° to 45° of the attached rotating roller 15. A storage battery 6 is fixedly connected to the middle of the top end of the support plate 1. The storage battery 6 is electrically connected to the lighting ring lamp 13. Multiple cooling slots 16 are opened at the bottom end of the support plate 1 to achieve heat dissipation of the lighting ring lamp 13.
[0030] During use, after the illumination ring light 13 is turned on, the battery 6 provides a stable power supply. The illumination ring light 13 projects uniform light outward. Its outer surface 17 and the red diffuse reflector 18 are specially optically designed to convert direct light into soft diffuse light. This dual diffuse reflection structure not only improves the uniformity of illumination, but also enhances the visual recognition of the display area, making the angle indication clearer and more eye-catching. This lighting system effectively optimizes the operating experience in nighttime or low-light environments, significantly improves the ease of observation and control accuracy of angle adjustment, and provides medical staff or users with intuitive and comfortable angle adjustment assistance.
[0031] Working principle: Multiple mounting plates 8 are installed with pre-drilled holes at the head of the bed, their holes corresponding to the pre-drilled holes. Bolts are driven in to fix them in place. The counterweight arc block 7 exerts a downward vertical force on the gravity adjustment ring 5. The indicator blocks 12 on both sides indicate the position of surface 19 as 0°. The four-quadrant angle display of 19 is 90°. When adjusting the head of the bed to raise its height, the counterweight arc block 7 applies a downward force to the gravity adjustment ring 5 when the head of the bed rotates, causing the angle display frame 2 to rotate. The angle indicated by the indicator block 12 changes, allowing for precise adjustment of the head of the bed's elevation angle. Simultaneously, during use, the illumination ring light 13 is activated, powered by the battery 6. The illumination ring light 13 illuminates outwards. Its outer surface 17 and the red diffuse reflector 18 are brightly illuminated, and through their diffuse reflection, the brightness of the light is softened, making the display areas of 17 and the red diffuse reflector 18 more prominent, further facilitating angle control.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
