Description

Technical Field

[0001] The utility model relates to a nursing bed, more specifically, to a multifunctional nursing bed with a tiltable bed surface. Background Art

[0002] Long-term bed rest can cause long-term pressure on parts of the body, resulting in obstructed blood circulation and prone to bedsores. Turning the patient over to move the body can not only effectively prevent the formation of bedsores, but also relieve the discomfort of patients lying in bed for a long time. However, for medical staff and patients' families, turning the patient over is a very arduous task. For this reason, more and more nursing bed manufacturers have begun to develop nursing beds with turning functions.

[0003] Most of the existing turning nursing beds use different bed surface rotation movements such as one-half or one-third to drive the human body to turn over sideways. The turning bed with a one-half bed surface design divides the bed surface into two parts, left and right, and uses one side of the bed surface to flip upward to push the patient to turn over to the other side. The turning bed with a one-third bed surface design divides the bed surface into three parts, left, middle and right. Generally, the turning method is to rotate the left and right sides of the bed surface, and there is also a method of turning over by rotating the middle bed surface. This kind of turning nursing bed can effectively assist patients in turning over, but the disadvantage is that the turning structure is complicated. While maintaining the original functions of the nursing bed such as back lifting and leg flexion, the bed board needs to be designed into several assembled structures, which increases the structural complexity and manufacturing cost of the nursing bed, and also increases the use cost of the nursing bed users (such as hospitals) and families. Summary of the invention

[0004] 1. Technical problems to be solved by the utility model

By making the bedridden patient's body tilt left and right, local body pressure is relieved, back blood circulation is improved, and bedsores are prevented. Turning over is assisted by the tilting of the bed surface, which can also make turning over nursing easier and reduce the labor intensity of medical staff and patients' families.

DETAILED DESCRIPTION

[0035] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0036] [Example]

[0037] Combination Figures 1 to 5As shown, a multifunctional nursing bed with a tiltable bed surface in this embodiment includes a lower bed frame 1, a lifting mechanism 2, an upper bed frame 3, a bed surface support frame 4, a tilting drive mechanism 5 and a bed board assembly 6. The upper bed frame 3 is arranged on the upper part of the lower bed frame 1 through the lifting mechanism 2. The height of the nursing bed can be controlled by the lifting mechanism 2. The above-mentioned lifting mechanism 2 preferably adopts an "X"-shaped connecting rod or a "y"-shaped connecting rod lifting structure, and the lifting control is realized by changing the connecting rod angle by an electric push rod. The specific structure is similar to the lifting mechanism of the existing nursing bed, and will not be described in detail here. Casters 1-1 are also provided at the four corners of the lower bed frame 1 to facilitate the movement of the nursing bed. The casters 1-1 preferably adopt casters with self-locking function, which can fix the nursing bed. The bed surface support frame 4 is installed on the upper bed frame 3, and the bed board assembly 6 is arranged on the bed surface support frame 4 to support the patient. The middle of the front and rear ends of the upper bed frame 3 are provided with a rotating shaft seat 3-1 respectively. The middle of the front and rear ends of the bed support frame 4 are respectively installed on the rotating shaft seat 3-1 at the corresponding end through the rotating shaft 4-1 to rotate coaxially, so that the bed support frame 4 can swing around the axis of the rotating shaft 4-1. The tilting drive mechanism 5 is arranged between the upper bed frame 3 and the bed support frame 4, and is used to drive the bed support frame 4 to rotate and tilt to the left or right relative to the upper bed frame 3. The formation of bedsores is due to the obstruction of blood circulation caused by long-term pressure on the body. By tilting the bed support frame 4 to the left and right, the patient can be placed in a tilted position, so that the pressure on the upper body is reduced, which can improve blood circulation. Switching the patient's tilted position every once in a while (such as 0.5 to 1 hour) can avoid long-term pressure on a part of the body and lack of blood circulation, thereby preventing the formation of bedsores. Moreover, turning over is assisted by tilting the bed surface, which can also make turning over nursing easier and reduce the labor intensity of medical staff and patients' families. Compared with the existing turning over nursing beds, it has a simpler structure, lower manufacturing cost, and is safer and more reliable to use.

[0038] In this embodiment, the maximum tilt angle of the bed support frame 4 relative to the upper bed frame 3 is preferably 15°, which can prevent the patient from rolling down due to excessive tilt angle, and is safer to use. By setting the time to switch the tilt direction of the bed surface, the patient can repeatedly maintain a left-right tilted position, which can share the pressure on one side of the body, promote blood circulation, and prevent the formation of bedsores. Furthermore, the front and rear ends of the bed support frame 4 are also provided with limit cross bars 4-2, and the limit cross bars 4-2 contact and limit the side frame of the upper bed frame 3 when the bed support frame 4 rotates and tilts to the maximum tilt angle, that is, when the bed support frame 4 rotates, the limit cross bars 4-2 rotate together, and the side of the limit cross bars 4-2 that swings downward can contact the side frame of the upper bed frame 3, at this time, the bed support frame 4 is restricted from continuing to rotate, and the maximum tilt angle is limited by the limit cross bars 4-2, which is safer to use. In addition, the front and rear rotating shafts 4-1 of the bed support frame 4 are respectively supported between the ends of the bed support frame 4 and the limiting cross bars 4-2 on the corresponding sides, supporting the rotating shaft 4-1 from both ends to ensure the stability of the rotating shaft installation and improve the bearing capacity of the bed support frame.

[0039] The above-mentioned tilting driving mechanism 5 can be an existing structure for driving the bed support frame 4 to rotate, such as a motor acting on the bed support frame 4 or the rotating shaft 4-1. Specifically in this embodiment, the tilting driving mechanism 5 is an electric push rod, one end of which is hinged to one side of the upper bed frame 3, and the other end is hinged to the connecting rod 4-3 of the bed support frame 4. The bed support frame 4 is driven to tilt by the telescopic movement of the electric push rod. The tilting driving mechanism 5 has a simple structure and is easy to control. The electric push rod has better support for the bed support frame 4. When the bed support frame 4 is subjected to unilateral force in a horizontal state, the structural stability of the bed support frame 4 can be maintained, thereby ensuring the bearing capacity of the bed support frame 4.

[0040] like Figure 2 and Figure 6As shown, a multifunctional nursing bed with a tiltable bed surface in this embodiment, the bed board assembly 6 includes a back bed board 6-1, a buttocks bed board 6-2, a thigh bed board 6-3 and a calf bed board 6-4, the buttocks bed board 6-2 is fixed to the middle of the bed support frame 4, and the back bed board 6-1 is close to the buttocks bed board 6-2.

During the leg bending process, the thigh bed board 6-3 can be appropriately moved toward the foot of the bed under the action of the four-bar mechanism during the upward flipping process, and at the same time, one side of the calf bed board 6-4 is lifted synchronously, thereby improving the comfort of leg bending.

One end of the back-lifting driver 7-1 is hinged on the bed support frame 4, and the other end is hinged with the back-lifting swing arm 7-3. The back-lifting driver 7-1 is preferably an electric push rod. The back-lifting driver 7-1 is telescopic and drives the back-lifting shaft 7-2 to rotate through the back-lifting swing arm 7-3, thereby driving the back-lifting support rod 7-4 and the back-lifting support roller 7-5 to lift upward. The leg-curling mechanism 8 includes a leg-curling driver 8-1, a leg-curling shaft 8-2, a leg-curling swing arm 8-3, a leg-curling support rod 8-4 and a leg-curling support roller 8-5.
