Description

Technical Field

[0001] This utility model relates to the field of medical bed frames, and in particular to a turning device for elderly patients. Background Technology

[0002] Among hospitalized patients, some require prolonged bed rest. Maintaining one position for extended periods can compress blood vessels, affecting blood circulation and leading to bedsores and other adverse consequences, especially for larger and heavier patients. Furthermore, many patients require turning over for examinations, treatments, and changing clothes.

[0003] Traditional hospital bed frames typically rely on the rotation of the bed board to allow patients to turn at certain angles, such as turning to the left or right, lifting the head, or lifting the legs and bending them. However, this cannot meet the needs of patients who frequently need to turn over. To enable patients to turn over, multiple medical staff are usually required to work together, and certain operational training and technical skills are necessary, and the work is quite labor-intensive. Utility Model Content

The first sprocket is connected to a third sprocket via a first chain, and the second sprocket is connected to a fourth sprocket via a second chain. The third sprocket and the fourth sprocket are respectively located at the output ends of a first motor and a second motor. Both the first motor and the second motor are located on the bed frame.

[0007] A reset device is provided below both the first and second wrapping shafts. One end of the reset device is rotatably connected to the bed frame, and the other end abuts against the upper surface of the turning cloth.

[0008] Furthermore, the lifting device includes two V-shaped rods, the bottom ends of which are rotatably connected to the left and right ends of the chassis, respectively, and the top ends of which are rotatably connected to the bottom end of the bed frame. The middle positions of the two V-shaped rods are connected by a first connecting rod, and the middle position of the first connecting rod is rotatably connected to the telescopic end of the electric push rod, which is rotatably connected to the chassis.

[0009] Furthermore, the reset device includes a reset shaft that abuts against the upper surface of the turning cloth. Both ends of the reset shaft are provided with L-shaped support plates, which are rotatably connected to the reset shaft. The support plates are rotatably connected to the bed frame via a second connecting rod.

[0024] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 3 As shown, this embodiment discloses a geriatric nursing turning device, including a chassis 1. Lifting devices 2 are provided at both the front and rear ends of the chassis 1. A bed frame 3 is provided at the top of the two lifting devices 2. A bed board 4 is provided on the bed frame 3, and a mattress 5 is provided on the bed board 4. A turning device 6 is provided above the mattress 5. The turning device 6 includes a turning cloth 601. The turning cloth 601 is wrapped around both the left and right ends multiple times and then fixed to a first wrapping shaft 602 and a second wrapping shaft 603. The first wrapping shaft 602 and the second wrapping shaft 603... 3 are rotatably connected to the left and right ends of the bed frame 3 respectively. The first sprocket 604 and the second sprocket 605 are respectively provided on the first wrapping shaft 602 and the second wrapping shaft 603. The first sprocket 604 is connected to the third sprocket 607 through the first chain 606, and the second sprocket 605 is connected to the fourth sprocket 609 through the second chain 608. The third sprocket 607 and the fourth sprocket 609 are respectively located at the output ends of the first motor 610 and the second motor 611. The first motor 610 and the second motor are both located on the bed frame 3.

[0026] A reset device 7 is provided below both the first wrapping shaft 602 and the second wrapping shaft 603. One end of the reset device 7 is rotatably connected to the bed frame 3, and the other end rests against the upper surface of the turning cloth 601.

[0027] In this embodiment, the lifting device 2 includes two V-shaped rods 201. The bottom ends of the two V-shaped rods 201 are rotatably connected to the left and right ends of the chassis 1, respectively. The top ends of the V-shaped rods 201 are rotatably connected to the bottom end of the bed frame 3. The middle positions of the two V-shaped rods 201 are connected by a first connecting rod 202. The middle position of the first connecting rod 202 is rotatably connected to the telescopic end of the electric push rod 203. The electric push rod 203 is rotatably connected to the chassis 1.

[0028] like Figure 4 As shown, in this embodiment, the reset device 7 includes a reset shaft 701, which abuts against the upper surface of the turning cloth 601. Both ends of the reset shaft 701 are provided with L-shaped support plates 702, which are rotatably connected to the reset shaft 701. The support plates 702 are rotatably connected to the bed frame 3 via a second connecting rod 703. One end of the second connecting rod 703 is connected to the bed frame 3, and the other end is rotatably connected to the support plate 702. A torsion spring 704 is sleeved on the second connecting rod 703. One end of the torsion spring 704 is fixed to the bed frame 3, and the other end is fixed to the support plate 702.

[0029] like Figure 5 As shown, in this embodiment, the middle position of the support piece 702 abuts against the positioning pin 705, and the positioning pin 705 is inserted into the bed frame 3.

[0030] In this embodiment, both the first sprocket 604 and the second sprocket 605 are ratchet-type unidirectional sprockets, such as the freewheel of a bicycle. The first sprocket 604 can transmit torque only when it rotates counterclockwise, and the second sprocket 605 can transmit torque only when it rotates clockwise.

[0031] In this embodiment, a guardrail 8 is provided around the top of the bed frame 3 to prevent the patient from falling off the bed.

[0032] In this embodiment, the bottom of the chassis 1 is provided with casters 9 to facilitate moving the hospital bed to a different position.

[0033] The usage process of this utility model is as follows:

[0034] like Figure 6As shown, the electric push rod 203 on the lifting device 2 is activated to adjust the bed frame 3 to a suitable height. When it is necessary to turn the patient counterclockwise, the positioning pin 705 inserted into the right end of the bed frame 3 is pulled out, and the second motor 611 is started. The second motor 611 drives the second wrapping shaft 603 to rotate clockwise, causing the turning cloth 601 to tilt and move to the right. At this time, the caregiver pushes the upper side of the patient to the left. The patient turns over under the joint action of the caregiver and the turning cloth 601. After the turning is completed, the reset device 7 resets the turning cloth 601, so that the turning cloth 601 is laid flat on the mattress 5 again. After the reset is completed, the positioning pin 705 is inserted. When it is necessary to turn the patient clockwise, the same operation can be performed.

[0035] More specifically, the working process of the reset device 7 is as follows: When it is necessary to reset the turning cloth 601, the support plate 702 rotates downward under the action of the torsion spring 704, and the reset shaft 701 presses the turning cloth 601 onto the mattress 5.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
