Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electric nursing bed with anti-slip function, which is suitable for hospital, nursing home and home care scenarios, especially for patients with limited mobility and long-term bed rest, and can effectively avoid the risk of patients slipping and falling during bed movement, turning over or nursing operations. Background Technology

[0002] Currently, electric nursing beds are widely used in nursing settings because they allow for adjustable bed board angles (such as backrest elevation and leg flexion), greatly facilitating daily positioning adjustments for patients and operations for caregivers. Their electric drive enables multi-angle bed board adjustment (such as backrest elevation to assist with eating and leg flexion to promote blood circulation), significantly reducing the physical burden on caregivers and improving the comfort of bedridden patients. However, existing electric nursing beds generally suffer from insufficient anti-slip functionality.

[0003] 1. Different patients have different heights, weights, and bed rest postures. Existing anti-slip structures cannot dynamically adjust the protection intensity according to the actual condition of the patient. For example, when the patient lifts their foot, the lateral force increases, and the anti-slip requirement is higher, but traditional structures cannot respond in real time.

[0004] 2. Most nursing beds only prevent side slipping by fixing the guardrails. The guardrails are fixed in height and need to be folded manually, which is not only cumbersome to operate, but also prone to slipping due to the guardrails not matching the patient's body shape, the bed frame being close to the bed surface or sheets, etc., when the lying position is adjusted. The squeezing or through-fixing method is also cumbersome to use. Utility Model Content

[0005] In view of the shortcomings of existing bed technology, such as the tendency for bed boards to slip sideways and the risk of patients slipping off the bed when lying down after adjusting the bed board at multiple angles, this utility model provides an electric nursing bed with anti-slip function, which has the advantages of effectively avoiding the risk of side slippage when patients turn over and adjust their body position, and improving the success rate of protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a bed frame, an electrically connected bed board assembly, a height-adjustable side rail anti-slip assembly, a bed surface anti-slip structure, and a control system. A buttock board is fixedly installed at the middle position of the upper part of the bed frame. A backrest board is hinged to one side of the buttock board via a hinge shaft, and a legrest board is hinged to the other side of the buttock board via a hinge shaft. Height-adjustable side rail anti-slip assemblies are fixedly installed on the front and rear sides of the upper part of the bed frame. A bed surface anti-slip structure is provided on the top of both the backrest board and the legrest board. The height-adjustable side rail anti-slip assembly includes an arc-shaped side rail, an electric lifting rod, and a pressure sensing module.

[0007] A base support is provided at the bottom of the buttocks bed board. A first electric telescopic rod is fixedly connected to the right side of the base support. A second electric telescopic rod is hinged to the connecting end of the first electric telescopic rod. A slider is slidably connected to the bottom of the leg bed board. The connecting end of the slider is hinged to the output end of the second electric telescopic rod. The output end of the second electric telescopic rod is slidably connected after being limited by an extension plate on the base support. Two sets of third electric telescopic rods are hinged to the left side of the base support. The connecting end of the crossbeam at the bottom of the back bed board is hinged to the output end of the third electric telescopic rod.

[0008] Preferably, two sets of the adjustable side guard anti-slip components are symmetrically arranged along the length of the bed, located on the two sides of the buttocks board and the back board, respectively. The arc-shaped side guard is made of medical ABS material and has an arc-shaped cross-section. The electric lifting rod drives the arc-shaped side guard to rise and fall through the control system. The pressure sensing module is embedded in the arc-shaped side guard and the two sides of the bed frame.

[0009] Preferably, the anti-slip structure of the bed surface includes a medical silicone anti-slip layer, an electric raised plate is fixedly installed on the side of the medical silicone anti-slip layer, and a linear brake is arranged and installed at the lower part of the electric raised plate. The electric raised plate is directly rigidly connected, and the bottom of the electric raised plate is directly connected through the telescopic end flange of the linear brake. The emergency lifting function is fixedly connected through the grooved piston rod and lifting ring on the linear brake. The electric raised plate is a uniformly distributed hemispherical raised plate.

[0010] Preferably, the control system includes an internally installed microcontroller and an externally installed control panel. An emergency stop button is installed on one side of the control panel. The control panel is located near the leg bed board, and the microcontroller is electrically connected to the electric lifting rod of the adjustable side rail anti-slip assembly and the pressure sensing module. The control system also has a battery installed inside, which is electrically connected to the first electric telescopic rod, the second electric telescopic rod, and the third electric telescopic rod in conjunction with the microcontroller.

[0011] Preferably, four rubber pads are fixedly installed on the support column at the bottom of the bed frame. Each rubber pad has a side opening, and the inside of the side opening has a threaded hole.

[0012] Preferably, the extension plate of the base bracket is slidably connected to the output end of the first electric telescopic rod, which helps to ensure the stability of the sliding stroke. The telescopic length of the second electric telescopic rod is less than that of the first electric telescopic rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the side rails can be dynamically raised and lowered according to the patient's position, and the anti-slip layer increases the friction, effectively avoiding the risk of side slippage when the patient turns over or adjusts their position. The anti-slip layer and the electric protrusion plate limit the bed board from slipping due to large tilt.

[0015] 2. In this utility model, the backrest bed board is tilted and adjusted by the tilting support of the two third electric telescopic rods. When the backrest bed board is tilted, it can distribute the force to bear a large reaction force. The leg bed board can be tilted in an unfolded state to help the patient lift their feet. The swing and telescopic functions of the two electric telescopic rods can also help adjust the tilt height when the patient lifts their feet. When the patient bends their knees, the bending degree setting is set to keep the feet suspended. Attached Figure Description

[0022] 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.

[0023] Example:

[0024] Please see Figures 1-5 An electric nursing bed with anti-slip function includes a bed frame 1, an electric connecting bed board assembly, a height-adjustable side rail anti-slip assembly, a bed surface anti-slip structure, and a control system 2. The bed frame 1 is a rectangular frame made of 304 stainless steel. The bottom of the frame is equipped with universal wheels with brakes to facilitate the movement and fixation of the bed. The top of the frame has a reserved mounting groove for fixing the electric adjustable bed board assembly and the height-adjustable side rail anti-slip assembly. A buttock bed board 3 is fixedly installed in the middle of the upper part of the bed frame 1. A back bed board 4 is hinged to one side of the buttock bed board 3, and a leg bed board 5 is hinged to the other side of the buttock bed board 3. Each area is connected to the bed frame 1 by a corresponding electric telescopic rod to meet the patient's requirements for sitting up, bending knees, and raising legs. The front and rear sides of the upper part of the bed frame 1 are fixedly equipped with height-adjustable side rail anti-slip assembly. The back bed board 4 and the leg bed board 5 are both equipped with a bed surface anti-slip structure. The height-adjustable side rail anti-slip assembly includes an arc-shaped side rail 6, an electric lifting rod 7, and a pressure sensing module 8.

[0025] A base support 16 is located at the bottom of the buttocks bed board 3. A first electric telescopic rod 17 is fixedly connected to the right side of the base support 16. A second electric telescopic rod 18 is hinged to the connecting end of the first electric telescopic rod 17. A slider 19 is slidably connected to the bottom of the leg bed board 5. The connecting end of the slider 19 is hinged to the output end of the second electric telescopic rod 18. The output end of the second electric telescopic rod 18 is limited by an extension plate on the base support 16 and then slidably connected. The lateral movement of the first electric telescopic rod 17 and the swinging and telescopic functions of the second electric telescopic rod 18 facilitate the adjustment of the tilt height when the patient lifts their legs. The bending degree setting can also be set when the patient bends their knees to maintain the suspension of the feet. To prevent slippage during manual adjustments that could affect the posture adjustment and nursing operations of the electric nursing bed, and to effectively prevent instability caused by personnel sliding sideways, two sets of third electric telescopic rods 20 are hinged on the left side of the base support 16. The crossbeam connection end at the bottom of the backrest 4 is hinged to the output end of the third electric telescopic rod 20, so that the backrest 4 can distribute the force to withstand a larger reaction force when tilted. The force intensity is dynamically adjusted according to the patient's condition by the distribution of the third electric telescopic rods 20 on both sides, so that the electric drive structure can maintain stable movement during sitting up, leg raising, and knee bending, avoiding the instability caused by the slippage of the mechanical structure.

[0026] Two sets of adjustable side guard anti-slip components are symmetrically arranged along the length of the bed, located on the sides of the buttocks board 3 and the back board 4, respectively. The arc-shaped side guard 6 is made of medical-grade ABS material and has an arc-shaped cross-section. The electric lifting rod 7 drives the arc-shaped side guard 6 to rise and fall through the control system 2. Pressure sensing modules 8 are embedded in the arc-shaped side guard 6 and the sides of the bed surface of the bed frame 1, respectively. The pressure sensing modules 8 are used to detect the contact pressure between the patient's body and the side guard and the distance of the patient from the side of the bed. The side guard is raised and lowered through the control system 2. The arc-shaped side guard 6 is adjustable and forms an effective protective barrier when it is at its lowest position and at its highest position, achieving the effect of dynamically adjusting the protective state of the arc-shaped side guard 6. The anti-slip structure of the bed surface includes a medical-grade silicone anti-slip layer 9. An electric convex plate 10 is fixedly installed on the side of the sliding layer 9. Linear brakes are arranged and installed at the lower part of the electric convex plate 10. The electric convex plate 10 is directly rigidly connected, and the bottom of the electric convex plate 10 is directly connected to the extension flange of the linear brake. The linear brake is fixed by bolt connection embedded in the bed plate slot. This method is suitable for short-stroke convex plates. When the linear brake extends or retracts, it directly pushes or pulls the convex plate to move vertically. The linear brake connector uses a medical-grade M12 round connector to prevent liquid (such as disinfectant) from entering. The connection between the linear brake and the control system 2 adopts closed-loop control. The core structure is a control layer with the control system 2 as the main component and built-in control logic switches. The drive layer is the dedicated starting module Linak built into the linear brake. The CA40 control box converts control signals into motor drive current. The linear brake itself receives the drive signal and performs the extension / retraction action, while simultaneously transmitting the position status back to the control system 2 via feedback signals. The final display is shown as an image on the control panel 2. Emergency lifting is achieved through a grooved piston rod and lifting ring fixed to the linear brake. The linear brake, model LA31 and manufactured by Karin, is a medical device specifically designed for hospital beds in home care, nursing homes, or hospital environments. The electric raised plate 10 consists of evenly distributed hemispherical protrusions. A medical-grade silicone anti-slip layer 9 increases the friction between the bed surface and the patient's clothing and skin. The anti-slip layer is fixed to the bed board with Velcro. The electric raised plate 10 directly limits and fixes the protrusions of the bed board downwards as the tilt surface changes. This allows for easy disassembly and replacement of the bed board while preventing slippage during tilting.

[0027] The control system 2 includes an internally installed microcontroller and an externally installed control panel 11. An emergency stop button 12 is installed on one side of the control panel 11. The control panel 11 is located near the leg bed board 15, and the microcontroller is electrically connected to the electric lifting rod 7 of the adjustable side guard anti-slip assembly and the pressure sensing module 8. The control system 2 also has a battery installed inside, which is electrically connected to the first electric telescopic rod 17, the second electric telescopic rod 18, and the third electric telescopic rod 20 in conjunction with the microcontroller. The side guard height can be manually set, and the automatic protection mode can be turned on or off. The system also displays the effect of the angle of each bed board and the status of the side guard. Four rubber pads 13 are fixedly installed on the support columns at the bottom of the bed frame 1. The rubber pads 13 have side openings 14. The side opening 14 has a threaded hole 15 inside; by setting a rubber pad 13, it can directly contact the ground to provide stable support for the bed, and can also be fixedly installed with universal casters to ensure compatibility, further improving the adaptability of the electric nursing bed; the extension plate of the base support 16 is slidably connected to the output end of the first electric telescopic rod 17, which helps to ensure the stability of the sliding stroke; the telescopic length of the second electric telescopic rod 18 is less than the telescopic length of the first electric telescopic rod 17; by setting the tilting support of the second electric telescopic rod 18 outward tilting angle, it is beneficial to help the patient lift their feet after the bed board is tilted; the inward tilting angle of the second electric telescopic rod 18 is beneficial to make the bed board tilted into a triangular shape after folding, which is beneficial for the patient to lie on the bed with their knees bent.

[0028] Working principle:

[0029] Step 1: Nurses can select "Manual Adjustment" on the touch control panel 11 to independently control the raising and lowering of the backrest 4 or the legrest 5. They can also manually set the height of the adjustable side rail anti-slip components. For example, when the patient needs to turn over, the side rail can be lowered to 5cm or raised to 20cm.

[0030] Step 2: After "automatic protection" is activated, the pressure sensing module 8 monitors the patient's status in real time. When the patient's body is close to the side of the bed or unconsciously leans against the side rail, the microcontroller immediately drives the arc-shaped side rail 6 to rise to the default height.

[0031] Step 3: When the patient needs to sit up, the control system 2 drives the two sets of third electric telescopic rods 20 to change the tilt angle of the backrest bed board 4, drive the first electric telescopic rod 17 to move laterally and the second electric telescopic rod 18 to swing and extend, which is beneficial for adjusting the tilt height when the patient lifts his feet. It can also set the degree of bending when the patient bends his knees to keep the feet suspended.

[0032] Step 4: In case of electrical failure or sudden discomfort of the patient, the nursing staff can press the emergency stop button 12 on the bed. All electric components will be immediately de-energized, the side rails will remain at their current height, and the bed board will stop adjusting. The system can be restarted after the fault is cleared.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
