Description

Technical Field

[0001] The present invention relates to the technical field of turning-over care, and particularly to a convenient turning-over auxiliary device for elderly rehabilitation care. Background Art

[0002] In the field of elderly rehabilitation care, regularly turning over bedridden elderly people is a crucial nursing procedure. This operation can not only effectively prevent the occurrence of pressure sores, but also is of great significance for promoting blood circulation and assisting in pulmonary expectoration, playing a decisive role in improving the rehabilitation effect and quality of life of the elderly. However, in the actual nursing process, many thorny problems are faced. Currently, the proportion of female nurses in the group of elderly rehabilitation care personnel is relatively large, and the elderly patients under care often have a large body weight and lack the ability of independent limb movement due to reasons such as age growth and physical function decline. In this case, it is extremely difficult for nurses to manually help the elderly turn over, and it also requires a lot of physical strength, which is likely to cause occupational injuries such as muscle strain for nurses. At the same time, it is difficult to ensure the standardization and safety of the turning-over operation, and there is a risk of secondary injuries such as muscle strain and joint sprain for the elderly due to improper operation.

[0003] In order to reduce the labor intensity of nurses helping the elderly turn over, there are some nursing turning-over devices on the market. For example, a portable fully automatic turning-over nursing mattress disclosed in a Chinese patent with the publication number CN211271804U is composed of a bottom pad, an independent turning-over frame, a turning-over air chamber, a supporting pad, an air duct, an air pump and a control system. The bottom pad has a flexible and anti-slip reverse side, and there are several independent turning-over frames arranged along the surface of the bottom pad on the front side; the independent turning-over frame is composed of a bottom plate, a supporting plate hinged at one end and a turning-over air chamber therebetween. The length direction of the bottom plate of each independent turning-over frame is parallel to the width direction of the bottom pad, and the hinged ends of adjacent independent turning-over frames are reversed. The turning-over air chambers of odd-numbered independent turning-over frames and the turning-over air chambers of even-numbered independent turning-over frames are respectively connected in parallel by different air ducts and then communicated with the air pump through corresponding valves; there is a flexible supporting pad on the turning-over frame group composed of all independent turning-over frames, and the bottom of the supporting pad is elastically connected to the central part and the unhinged end of the supporting plate of each independent turning-over frame.

[0004] Although the turning-over nursing mattress disclosed in the above patent can effectively realize the turning-over treatment of the elderly, for nursing institutions, using the above turning-over nursing mattress will significantly increase their operating costs and at the same time increase the fees paid for the care of the elderly. Because, if one wants to use the turning-over nursing mattress to assist nurses in turning over the elderly, it is necessary to equip each elderly person with a turning-over nursing mattress, and the number is still relatively large.

For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] The following is further described in conjunction with the accompanying drawings and specific embodiments:

[0031] Embodiment 1

[0032] In order to reduce the labor intensity of nursing staff for turning over and nursing the elderly, this embodiment provides a turning-over assistance device, which can be carried by the staff to a certain bed, that is, it is not necessary to be equipped for each bed where the elderly are nursed, relatively reducing the cost of turning-over nursing.

[0033] Such as Figure 1 , Figure 2 , Figure 7As shown in the figure, specifically, the turning-over assisting device includes a support frame 2, a winding mechanism 5, a winding rod 3, etc. The bottom of the support frame 2 is detachably installed on the edge of the bed body 1, and it presses the bedsheet to fit and rest on the edge of the bed body 1. At the same time, it can adjust its own height under the action of an external force, thereby adjusting the position of the winding mechanism 5. In the case of adapting to the elderly of different body types, the flexibility of the assisting device is improved, which is convenient for the nursing staff to carry. A rope is wound on the winding mechanism 5 installed on the top of the support frame 2. The free end of the rope is tied with a connecting device, and the connecting device is clamped on the winding rod 3. The extending length of the rope can be changed by the operation of the winding mechanism 5, thereby adjusting the position of the winding rod 3. When the position of the winding rod 3 can be adjusted, the edge of the bedsheet far from the support frame 2 can be wound on the winding rod 3, and then the edge of the bedsheet is pulled to move under the action of the winding mechanism 5. During the movement of the bedsheet, one side of the elderly can be pried to realize the turning-over of the elderly, thereby reducing the nursing intensity of the nursing staff.

[0034] As Figure 2 , Figure 5 shown, in order to control the movement of the winding rod 3 through the operation of the winding mechanism 5, the winding mechanism 5 includes a motor 51 (which can be set as a stepping motor, a servo motor, etc.) and a winding disc 52. The central axis of the winding disc 52 is connected to the power output shaft of the motor 51 through a coupling. And the end of the central axis of the winding disc 52 is sleeved with a bearing seat 53. The bearing seat 53 is installed on the support frame 2. At the same time, the motor 51 is installed on the top of the support frame 2. In addition, the motor 51 is connected to the electrical control box 4. In addition, the power cord of the electrical control box 4 can be inserted into the socket in the nursing room. Therefore, after the support frame 2, the winding rod 3, and the connecting device enter their working states, the nursing staff can operate the electrical control box 4 to start the motor 51, forcing the winding disc 52 to rotate, thereby reducing the extending length of the rope and driving the winding rod 3 to move to realize the movement processing of the bedsheet.

[0035] In order to control the operation of the motor 51, at least a power supply module, a microcontroller, a motor driver, a relay, a push-button switch, etc. are equipped in the electrical control box 4, which is convenient for the staff to press the push-button switch to control the operation of the motor 51, the power supply module and the microcontroller of the electrical control box 4.

[0036] As Figure 7 , Figure 8As shown in the figure, in order to keep the bedsheet wound around the upper end of the winding rod 3 stationary relative to the winding rod 3, the connecting device includes a first clamping plate 31 and a second clamping plate 32, both of which are arc-shaped structures. The first clamping plate 31 and the second clamping plate 32 are spliced to form an arc-shaped space with a central angle greater than 180°. The winding rod 3 is arranged through the arc-shaped space. Thus, the bedsheet and the winding rod 3 are firmly clamped under the cooperation of the first clamping plate 31 and the second clamping plate 32, providing support for pulling the bedsheet to move. Similarly, when the first clamping plate 31 and the second clamping plate 32 move away from each other, the restriction on the bedsheet and the winding rod 3 is released, facilitating the turning care of the next elderly person.

[0037] As Figure 8 shown in the figure, in order to achieve the detachable connection between the first clamping plate 31 and the second clamping plate 32, plates are fixedly arranged on the tops of the first clamping plate 31 and the second clamping plate 32. The height of the plate on the top of the first clamping plate 31 is less than that of the plate on the top of the second clamping plate 32, and an installation groove 35 is arranged on the plate on the top of the second clamping plate 32. The plate of the first clamping plate 31 is arranged in the installation groove 35, and the top surface of the plate is in close contact with the top of the installation groove 35. A fastening bolt 34 is arranged through the top plate of the second clamping plate 32 in a bearing connection. The fastening bolt 34 is threaded through a threaded hole 33 above the first clamping plate 31. Therefore, when the fastening bolt 34 is rotated, the movement of the first clamping plate 31 relative to the second clamping plate 32 can be controlled, realizing the disassembly and assembly of the connecting device and the winding rod 3.

[0038] As Figure 3 、 Figure 4 shown in the figure, in order to detachably install the support frame 2 on the edge of the bed body 1, a pressure-receiving plate 26 is arranged at the bottom of the support frame 2.
