Technical Field
[0001] This utility model relates to the technical field of medical auxiliary equipment, and more specifically, to a detachable bed rail monitoring and alarm device. Background Technology
[0002] During hospitalization, rehabilitation, and observation, existing hospital beds typically have bed rails that can be lowered to facilitate patient movement or toileting. Patients can lower the rails themselves or with the assistance of family members or nurses when they need to get out of bed. However, some elderly patients, those with impaired balance, cognitive impairment, or poor communication and cooperation may overestimate their abilities and lower the rails to get out of bed without informing their caregivers. If caregivers do not notice in time, the patient may fall due to impaired balance or lower limb weakness, resulting in varying degrees of injury. Furthermore, to ensure patient safety, nurses need to frequently enter and exit different wards to check if patients have gotten out of bed on their own and to inquire if they need to get out, significantly increasing their workload due to unnecessary back-and-forth movements.
[0003] Existing devices for monitoring the lowering of hospital bed rails, such as those with patent numbers CN202120986994.4 and CN202420641725.8, can all detect whether the bed rails are lowered and issue an alarm if they are. However, these devices all require fixed installation on the bed, which incurs significant costs and time in modifying each bed, resulting in poor flexibility. Furthermore, not every patient in every bed needs the monitoring device, leading to waste. Therefore, there is an urgent need to design a more flexible bed rail monitoring device to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a detachable bed rail monitoring and alarm device. When this device is installed on the bed where needed, it can effectively monitor whether the patient in the bed has lowered the bed rail on their own and issue an alarm when the patient does so, thereby preventing the patient from falling. It has the characteristics of easy installation, good monitoring effect and good flexibility.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A detachable bed rail monitoring and alarm device includes a fixed frame, on which a limit switch, an alarm, a rechargeable battery, and a rotating rod are mounted. The rotating rod is a hook-shaped rod, with one straight end rotatably connected to the fixed frame via a bearing seat. The hook-shaped end of the rotating rod extends below the limit switch. An extension tube is provided on the outer side of the straight end of the rotating rod, with its inner end slidably connected to the rotating rod. The outer end of the extension tube is sleeved on the outside of the linkage tube that links the bed bottom side rail and the bed rail. Both ends of the extension tube are threaded with anti-screws, which are respectively tightened onto the rotating rod and the linkage tube. When the bed rail is lowered, the hook-shaped end of the rotating rod rotates to a horizontal position and triggers the limit switch. The limit switch is connected to the rechargeable battery and the alarm circuit. A fixing structure is provided on the rear side of the fixed frame for fixing the fixed frame to the bed bottom support.
[0007] Furthermore, the fixing structure includes a pair of U-shaped rods, the front sides of which are fixedly connected to the fixing frame, and the rear sides of which are threaded with anti-screws.
[0008] Furthermore, the inner walls of the pair of U-shaped rods are provided with anti-slip rubber pads.
[0009] Furthermore, the opening distance of the U-shaped rod is greater than the width of the support rod at the bottom of the hospital bed.
[0010] Furthermore, a self-locking switch is installed on the fixed frame, and the limit switch is connected to the alarm circuit through the self-locking switch.
[0011] Furthermore, one end of the linkage tube passes through the bottom side rail of the hospital bed and is fixedly connected to the bed railing, while the other end of the linkage tube extends out of the bottom side rail of the hospital bed.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model discloses a detachable bed rail monitoring and alarm device. It comprises a rotating rod mounted on a fixed frame, consisting of a limit switch, an alarm, a rechargeable battery, and a hook-shaped rod. One straight end of the rotating rod is rotatably connected to the fixed frame via a bearing seat. The hook-shaped end of the rotating rod extends below the limit switch. An extension tube is provided on the outer side of the straight end of the rotating rod. The inner end of the extension tube is slidably connected to the rotating rod, and the outer end of the extension tube is sleeved on the outside of the linkage tube that links the bed bottom side rail and the bed rail. Both ends of the extension tube are threaded with anti-screws, which are respectively tightened onto the rotating rod and the linkage tube. The extension tube extends the length of the straight end of the rotating rod, allowing it to be fixed to the outside of the linkage tube for linkage. The linkage tube, in turn, links with the bed rail, meaning that the rotation of the bed rail drives the rotating rod to rotate synchronously.
[0014] When the bed railing is lowered, the hook-shaped end of the lever rotates to a horizontal position and triggers the limit switch.

One straight end of the rotating rod 5 is rotatably connected to the fixed frame 1 via a bearing seat 6. The hook-shaped end of the rotating rod 5 extends below the limit switch 2. An extension cylinder 7 is provided on the outer side of the straight end of the rotating rod 5. The inner end of the extension cylinder 7 is slidably connected to the rotating rod 5. The outer end of the extension tube 7 is sleeved on the outside of the linkage tube 10 that links the side rail 8 at the bottom of the bed with the bed rail 9. Both ends of the extension tube 7 are threaded with anti-screws 11. The two ends of the extension tube 7 are respectively tightened onto the rotating rod 5 and the linkage tube 10 by the anti-screws 11. The extension tube 7 can extend the length of the straight end of the rotating rod 5 so that it can be fixed on the outside of the linkage tube 10 to achieve linkage with the linkage tube 10. The linkage tube 10 is also linked with the bed rail 9, that is, when the bed rail 9 rotates, it can drive the rotating rod 5 to rotate synchronously. When the bed rail 9 is lowered, the hook-shaped end of the rotating rod 5 rotates to the horizontal position and triggers the limit switch 2. The limit switch 2 is connected to the rechargeable battery 4 and the alarm 3 circuit. If the patient lowers the bed rail 9 by himself, the limit switch 2 is triggered to activate the alarm 3 to issue an alarm prompt, so as to attract the attention of medical staff or their accompanying family members and prevent them from falling off the bed, thereby preventing patient falls and providing good monitoring effect. The rear side of the fixed frame 1 is provided with a fixing structure for fixing the fixed frame 1 to the support rod 12 at the bottom of the hospital bed. When this device is needed, the fixed frame 1 can be fixed to the bottom of the hospital bed using the fixing structure. It can also be easily removed when not needed, making it convenient to install and flexible to use. Furthermore, the limit switch 2 is a Delixi LXJMS-8107.
[0027] Existing hospital beds such as Figure 7As shown, the basic frame of the bed is formed by the headboard, footboard, and side rails 8 on the left and right sides. Multiple bed bottom support rods 12 are set in the horizontal and vertical directions of the frame to support the bed board. Multiple bed rails 9 are hinged to the side rails 8 on both sides. Each bed rail 9 is provided with a linkage tube 10 at the hinge point between it and the side rail 8. One end of the linkage tube 10 passes through the side rail 8 and is fixedly connected to the bed rail 9, while the other end extends out of the side rail 8 on the side facing the support rod 12. The bed rail monitoring and alarm device of this utility model can be fixed on the bed bottom support rod 12 adjacent to and parallel to one of the bed bottom side rails 8. During installation, the extension tube 7 needs to be aligned with the linkage tube 10 of one of the bed rails 9. After aligning the position, the fixing bracket 1 is fixed to the bed bottom support rod 12 using the fixing structure. Loosen the anti-top screws 11 at both ends of the extension tube 7. Adjust the position of the extension tube 7 according to the distance between the linkage tube 10 and the rotating rod 5 so that the outer end of the extension tube 7 is fixed to the outside of the linkage tube 10. After adjusting the position of the extension tube 7, lower the bed rail 9. Use one hand to rotate the rotating rod 5 to the horizontal position to trigger the limit switch 2, and use the other hand to tighten the anti-top screws 11 at both ends of the extension tube 7.
[0028] Furthermore, the fixing structure includes a pair of U-shaped rods 13. The front side of the pair of U-shaped rods 13 is fixedly connected to the fixing frame 1. The rear side of the U-shaped rods 13 is threaded with a reverse screw 11. In use, the bed bottom support rod 12 can be inserted into the groove of the pair of U-shaped rods 13, and then the fixing bracket 1 can be fixed to the bed bottom support rod 12 by the reverse screw 11.
[0029] Furthermore, the inner walls of the pair of U-shaped rods 13 are provided with anti-slip rubber pads 14 to increase the friction of the bed bottom support rods 12 and make them more securely installed.
[0030] Furthermore, the opening distance of the U-shaped rod 13 is greater than the width of the bed bottom support rod 12, so as to ensure that the bed bottom support rod 12 can be inserted into the groove of the U-shaped rod 13.
[0031] Furthermore, a self-locking switch 15 is installed on the fixed frame 1, and the limit switch 2 is connected to the alarm 3 circuit through the self-locking switch 15. When the patient has a family member accompanying them, the alarm 3 can be temporarily turned off by using the self-locking switch 15 to prevent the alarm from disturbing the patient's rest.
[0032] Furthermore, one end of the linkage pipe 10 passes through the bottom side rail 8 of the hospital bed and is fixedly connected to the bed rail 9, while the other end of the linkage pipe 10 extends out of the bottom side rail 8 of the hospital bed to extend the length of the bed rail 9 and facilitate its fixed connection with the rotating rod 5.
[0033] The above description is only a preferred embodiment of the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
