Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a nursing bed that can prevent side slipping and sliding. Background Technology

[0002] Nursing beds are commonly used in hospitals or homes, primarily for patients with limited mobility. They facilitate caregivers in providing care for patients and allow users to sit up, lie down, and turn over.

[0003] Utility model patent CN 221331705 U discloses an electric nursing bed, including a bed frame and a movable base. The movable base has a movable groove at its upper end, with two threaded sliders slidably connected inside the groove. Each of the two threaded sliders has a movable slide plate fixedly connected to its upper end, slidably connected to the upper end of the movable base. Two hinge seats are fixedly connected to the upper end of the movable slide plates. A hinge plate is hinged to the upper end of each hinge seat, and a hinge seat is hinged to the upper end of the hinge plate and fixedly connected to the lower end of the bed frame. A moving mechanism is provided inside the movable groove. Two limiting plates are fixedly connected to both sides of the bed frame, and each limiting plate has a limiting circular plate at its upper end. This electric nursing bed allows for height adjustment between the bed frame and the ground, making it easier for patients to get onto the bed and improving its practicality.

[0004] When paralyzed patients or those unable to care for themselves use a nursing bed, the backrest frame of the bed is raised, causing them to tend to tilt to either side. Furthermore, when the backrest frame is raised, the user is in a sitting position, which makes them prone to sliding downwards, creating a safety hazard. Consequently, the nursing bed offers poor protection for the user. Therefore, this invention provides a nursing bed that can prevent side slipping and sliding down to meet this need.

[0024] The following is a detailed description of a nursing bed with anti-slip and anti-fall capabilities provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] like Figures 1 to 4As shown, this embodiment of the present invention provides a nursing bed that can prevent side slipping and sliding, including a bed frame 1. A first support pad 2 is rotatably connected to the middle of the top of the bed frame 1. A second support pad 3 is rotatably connected to the bottom of one side of the first support pad 2. A third support pad 4 is rotatably connected to the top of one side of the first support pad 2. Fourth support pads 5 are rotatably connected to the top of both sides of the third support pad 4. An anti-side slip component is used to prevent the patient from sliding sideways when sitting up. The anti-side slip component is connected to the bed frame 1 and includes a mounting plate fixedly connected to the back of the third support pad 4. A double-threaded screw 16 is rotatably connected inside the mounting plate. A set of third transmission blocks 17 are symmetrically threaded on the outside of the double-threaded screw 16. A third connecting rod 19 is rotatably connected to the top of the third transmission block 17. The other end of the third connecting rod 19 is connected to the bottom of the fourth support pad 5 away from the third support pad. One side of the support pad 4 is rotatably connected, and the other end of the center plate is rotatably connected to the second transmission screw 10. The external thread of the second transmission screw 10 is connected to the second transmission block 11. The top of the second transmission block 11 is rotatably connected to the second connecting rod 12. The other end of the second connecting rod 12 is rotatably connected to the bottom of the third support pad 4 away from the first support pad 2. One end of the second transmission screw 10, one end of the first transmission screw 6, and both ends of the double-threaded screw 16 are fixedly connected to the rotating disk 9. The bed frame 1 is fixedly connected to the reinforcing plate 13 below the connection between the first support pad 2 and the third support pad 4. The bed frame 1 is fixedly connected to the connecting column 14 below the anti-slip component. When the patient needs to sit up after lying flat on the nursing bed, the rotating disk 9 at one end of the second transmission screw 10 can be rotated. When the rotating disk 9 is rotated clockwise or counterclockwise, the second transmission screw 10 rotates accordingly. Since the second transmission screw 10 and the second transmission block 11 are connected by threads, rotating the screw will push or pull the second transmission block 11 to move along the screw axis. The movement of the second transmission block 11 is converted into the rotational motion of the third support pad 4 through the second connecting rod 12. Specifically, the top of the second connecting rod 12 is rotatably connected to the bottom of the third support pad 4 on the side away from the first support pad 2. Therefore, when the second transmission block 11 moves, it will drive the third support pad 4 to rotate around its connection point with the first support pad 2, thereby changing the tilt angle of the third support pad 4 and supporting the back of the bedridden patient. When the rotating disk 9 at one end of the double-threaded screw 16 is rotated, since a set of third transmission blocks 17 are connected to the external symmetrical threads of the double-threaded screw 16, the rotation will cause these two third transmission blocks 17 to move relative to or towards each other along the axis of the double-threaded screw 16.Because the top of the third transmission block 17 is rotatably connected to the bottom of the fourth support pad 5 via the third connecting rod 19, the movement of the third transmission block 17 will cause the fourth support pad 5 to move inward or outward along both sides of the nursing bed, thereby providing diagonal support to the patient's sides and preventing the patient from slipping. By rotating the rotating disk 9 of the double-threaded screw 16, the user can finely adjust the position of the fourth support pad 5 according to the patient's specific body shape and needs, ensuring that the patient receives optimal lateral support when sitting up and avoiding lateral slippage. This personalized adjustment function enhances the adaptability and flexibility of the nursing bed. When the fourth support pad 5 is adjusted to the appropriate position according to the patient's needs, it can provide the patient with solid lateral support, effectively preventing the patient from slipping due to loss of balance during sitting up or moving. This enhanced stability not only improves patients' sense of security but also reduces the burden on caregivers. By reasonably adjusting the tilt angle and position of support pads 4 (number three) and 5 (number four), it ensures that the patient's back and sides receive adequate support when sitting up, reducing discomfort and pain caused by prolonged bed rest or improper sitting posture, thus improving patient comfort. The entire adjustment process can be completed simply by using the rotating disc 9, making it simple and quick to operate without requiring complicated tools or specialized knowledge. This allows caregivers to easily adjust the nursing bed for patients, improving work efficiency and patient satisfaction.

[0026] In this embodiment, as Figures 1 to 4As shown, the anti-slip component is used to prevent the patient from sliding down when sitting up. The anti-slip component is connected to the bed frame 1. A center plate is fixedly connected inside the bed frame 1. The center plate is located below the connection between the first support pad 2 and the third support pad 4. The anti-slip component includes a first transmission screw 6 rotatably connected to the center plate. A first transmission block 7 is threadedly connected to the outside of the first transmission screw 6. A first connecting rod 8 is rotatably connected to the top of the first transmission block 7. The top of the first connecting rod 8 is rotatably connected to the bottom of the first support pad 2 near the second support pad 3. A limit post 20 is fixedly connected inside the bed frame 1. A sliding sleeve 21 is slidably connected to the outside of the limit post 20. The top of the sliding sleeve 21 is rotatably connected to the bottom of the second support pad 3 away from the first support pad 2. When it is necessary to adjust the position of the first support pad 2 to raise the patient's knee, the rotating disk 9 at one end of the first transmission screw 6 can be rotated. Since the first transmission screw 6 and the first transmission block 7 are connected by a thread, rotating the screw will cause the first transmission block 7 to move along the screw axis. The movement of the first transmission block 7 is converted into the rotational motion of the first support pad 2 through the first connecting rod 8. Specifically, the top of the first connecting rod 8 is rotatably connected to the bottom of the first support pad 2 near the second support pad 3. Therefore, when the first transmission block 7 moves, it will drive the first support pad 2 to rotate around its connection point with the bed frame 1 or other fixed points, thereby changing the tilt angle of the first support pad 2. At the same time, the second support pad 3 is slidably connected to the limiting post 20 through the sliding sleeve 21, providing additional support for the patient's knee. When the first support pad 2 is raised, the patient's knee will naturally be pushed towards the second support pad 3, forming a bending point. At this point, the buttocks naturally sink to the "lower point" formed by the first support pad 2, the second support pad 3, and the bed surface due to gravity, effectively preventing slippage. Through the above adjustments, the first support pad 2 and the second support pad 3 together form a stable lifting system that can adjust the height and angle according to the patient's needs, ensuring the patient maintains a stable posture during sitting up and preventing slippage. The anti-slip component provides a stable support environment for the patient by precisely adjusting the position of the first support pad 2 and the second support pad 3, effectively preventing slippage during sitting up or moving, improving the safety and comfort of the nursing bed. Users can adjust the position according to the patient's needs. The tilt angle and height of the support pad are adjusted by rotating the transmission screw according to the patient's specific body shape and needs, achieving personalized care and meeting the needs of different patients. The reasonable layout and adjustment mechanism of the support pad ensure that the patient receives sufficient support when sitting up, reducing physical discomfort and pain caused by improper posture or insufficient support, and improving patient comfort. The adjustment process is simple and quick, requiring no complicated tools or professional knowledge. Nursing staff can easily complete the operation, improving work efficiency and patient satisfaction. The setting of structural components such as the limiting column 20 and the sliding sleeve 21 enhances the structural stability of the nursing bed, ensuring the stability and reliability of the support pad during the adjustment process.

[0027] The working principle provided by this utility model is as follows: when it is necessary to sit up, the rotating disk 9 at one end of the second transmission screw 10 can be rotated. When the rotating disk 9 is rotated clockwise or counterclockwise, the second transmission screw 10 rotates accordingly. Since the second transmission screw 10 and the second transmission block 11 are connected by threads, rotating the screw will push or pull the second transmission block 11 to move along the screw axis. The movement of the second transmission block 11 is converted into the rotational motion of the third support pad 4 through the second connecting rod 12. Specifically, the top of the second connecting rod 12 is rotatably connected to the bottom of the third support pad 4 on the side away from the first support pad 2. Therefore, when the second transmission block 11 moves, it will drive the third support pad 4 to rotate around its connection point with the first support pad 2, thereby changing the tilt angle of the third support pad 4 and supporting the back of the bedridden patient. When the rotating disk 9 at one end of the double-threaded screw 16 is rotated, since a set of third transmission blocks 17 are connected to the external symmetrical threads of the double-threaded screw 16, the rotation will cause these two third transmission blocks 17 to move relative to or towards each other along the axial direction of the double-threaded screw 16. Since the top of the third transmission block 17 is rotatably connected to the bottom of the fourth support pad 5 through the third connecting rod 19, the movement of the third transmission block 17 will drive the fourth support pad 5 to move inward or outward along both sides of the nursing bed, thereby providing diagonal support for the patient's sides and preventing the patient from slipping. When it is necessary to adjust the position of the first support pad 2 to lift the patient's knees, the rotating disk 9 at one end of the first transmission screw 6 can be rotated. Since the first transmission screw 6 and the first transmission block 7 are connected by a thread, rotating the screw will cause the first transmission block 7 to move along the screw axis. The movement of the first transmission block 7 is converted into the rotational motion of the first support pad 2 through the first connecting rod 8. Specifically, the top of the first connecting rod 8 is rotatably connected to the bottom of the first support pad 2 near the second support pad 3. Therefore, when the first transmission block 7 moves, it will drive the first support pad 2 to rotate around its connection point with the bed frame 1 or other fixed points, thereby changing the tilt angle of the first support pad 2. At the same time, the second support pad 3 is slidably connected to the limiting post 20 through the sliding sleeve 21, providing additional support for the patient's knee. When the first support pad 2 is raised, the patient's knee will naturally be pushed towards the second support pad 3, forming a bending point. At this time, the buttocks will naturally sink to the "valley" formed by the first support pad 2, the second support pad 3, and the bed surface due to gravity, thereby effectively preventing slippage.
