Description

Technical Field

[0001] This invention belongs to the field of medical bed technology, and in particular relates to a fall-prevention alarm bed rail. Background Art

[0002] Hospital beds generally refer to nursing beds, which are designed according to the patient's treatment needs and bedridden lifestyle. They are designed to allow family members to accompany the patient and have multiple nursing functions and operation buttons.

[0003] Patient falls and bed falls have a huge impact on both hospitals and patients. Statistics show that most falls and bed falls occur at night. Analysis of the causes shows that patients fall and bed falls at night because they need to get up to use the toilet, and family members and nurses do not know in time to assist them, leading to the fall.

[0004] A fall-prevention alarm nursing bed is disclosed in invention patent CN 112426293 A, mainly addressing the problems of existing beds lacking fall-prevention warning devices or having devices that hinder patient exit from bed, and the inconvenience of changing nursing pads and detecting wetness. This fall-prevention alarm nursing bed includes a bed frame and an alarm device installed at the nurses' station. The bed frame has a headboard and a footboard at each end; folding guardrails are installed on both sides of the bed frame, and electromagnetic switches are installed on the opposite surfaces of the two folding guardrails and the opposite footboard; the electromagnetic switches are connected to the alarm device at the nurses' station. Through this solution, the invention achieves the purpose of notifying nurses to assist patients and prevent falls, possessing high practical and promotional value.

[0005] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0006] 1. The side rails of the hospital bed cannot be adjusted, which makes it difficult for patients to get in and out of bed and inconvenient to use, especially for heavier patients who may require assistance from multiple people.

[0007] Therefore, it is necessary to provide a new fall-prevention alarm bed rail to solve the above-mentioned technical problems. Summary of the Invention

One end of the movable rod 28 passes through the sealing ring 21 and is fixedly connected to the impact ball 32. The sealing ring 21 is adapted to the movable rod 28.

[0051] The control box 33 is installed at the bottom of the bed frame 2. The call bell 34 is installed on one side of the outer wall of the control box 33. One end of the connecting pipe 35 is connected to the bottom of the housing 18, and the other end of the connecting pipe 35 extends into the housing 26 and is connected to the housing 26. The foot rail 5 is equipped with a mounting block 36, and the mounting block 36 is equipped with a camera 37. The space on the left side of the sealing piston 29 is filled with gas. The gas filling the space on the left side of the sealing piston 29 is balanced with the gas filling the space below the sealing piston 21 and the gas in the connecting pipe 35, so that the telescopic spring 23 and the telescopic spring 30 are in normal state (not in a stretched or compressed state). One side of the outer wall of the bed frame 2 is equipped with a switch 38. The control box 33 is equipped with a battery module, a control module and a wireless transmission module. The battery module is connected to the call bell 34 through the switch 38. The call bell 34 is connected to the control module. The control module is connected to the call system at the patient's bedside through the wireless transmission module.

[0052] The bottom of the bed frame 2 is equipped with mounting block 39. An electric telescopic rod 40 is installed on one outer wall of mounting block 39. A connecting rod 41 is installed on the output shaft of the electric telescopic rod 40. A concave rod 42 is installed at one end of the connecting rod 41. Both ends of the concave rod 42 are in contact with the lower side guardrail 7.

[0053] The working principle of the fall-prevention alarm bed rail provided by this invention is as follows:

[0054] First step: When someone is watching the patient, the call bell 34 is turned off by switch 38. Therefore, when the patient needs to get out of bed, the side upper guardrail 8 can be pressed down. The side upper guardrail 8 will drive the side lower guardrail 7 and the connecting rod 15 to move downward. The connecting rod 15 will compress the mounting round rod 16, so that the side upper guardrail 8 is at the same level as the bed board 4 and lower than the top of the bed board 4, which makes it easier for the patient to get out of bed or get in bed to rest, thus reducing the difficulty for the patient to get in and out of bed.

[0055] Step Two: When the patient is unattended at night and needs to get out of bed, activate the electric telescopic rod 40 via switch 2 (43). The electric telescopic rod 40 moves the connecting rod 3 (41) and the concave rod 42 away from the lower side rail 7 (the installation positions of switches 2 (43) and 1 (38) are not limited; they can be installed where the patient can reach them). Activate the call bell 34 via switch 1 (38). Therefore, when the patient needs to get out of bed, they can press down the upper side rail 8. The upper side rail 8 moves the lower side rail 7 and the connecting rod 2 (24) downwards. The connecting rod 2 (24) will move the sliding plate 22, the moving rod 1 (20), and the sealing piston 1 (21) downwards. The downward movement of the sliding plate 22 will compress... The second telescopic spring 23, along with the downward movement of the first sealing piston 21, will release the gas in the space below the first sealing piston 21 into the second housing 26 through the connecting pipe 35, causing the air pressure in the second housing 26 to increase. This will cause the second sealing piston 29 to drive the second moving rod 28 and the impact ball 32 to move. The second sealing piston 29 will compress the third telescopic spring 30, and the impact ball 32 will come into contact with the call bell 34, causing the call bell 34 to remind the medical staff on duty, thus facilitating the nurses' assistance and allowing them to check the time the patient has been away from the bed through the camera 37. At the same time, if the patient has been away from the bed for too long, it will also remind the nurses to check and find the patient in time, thus preventing the patient from falling outside without anyone knowing.

[0056] Third step: If it is necessary to increase the height of the side rails, the height of the rails can be increased by rotating the two internal threaded swivels 9, causing the two threaded rods 10 to drive the side rails 8 to move upward. The bed board 4 can be lifted and moved away from the bed frame 2 by the four L-shaped handles 14, so that the bed board 4 can be replaced, which can save costs and eliminate the need to replace the entire hospital bed.

[0057] Fourth step: When the patient is unattended at night, activate the electric telescopic rod 40 by switching on switch 2 43. The electric telescopic rod 40 will drive the connecting rod 3 41 and the concave rod 42 to move, so that the concave rod 42 contacts the lower side railing 7, thus supporting the lower side railing 7 and preventing the patient from falling off the bed.

[0058] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
