Description

Technical Field

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

[0002] With the growth of age, affected by the aging of physical functions or diseases, some elderly people need to stay in bed for a long time. However, long-term bed rest can make the elderly's back stiff and uncomfortable, and even cause pressure sores in severe cases. Therefore, it is necessary to help the bedridden elderly turn over regularly, from lying flat to a side-lying position. Traditionally, people turn the elderly over manually, which requires a lot of manpower, and the elderly may be injured due to uneven force control during turning. For this reason, turning devices have been introduced to assist in turning over.

[0003] Existing auxiliary turning devices include a nursing bed and a pair of turning boards arranged on the nursing bed. The pair of turning boards are driven externally to rotate in different directions to assist the elderly lying on the turning boards to turn over. Although the above solution can assist the elderly in turning over, it still has certain problems. Since there is no corresponding support on the pair of turning boards, when one side of the turning board rotates to lift the elderly to one side, the elderly will slide down due to their body weight, which will not only affect the turning of the elderly, but also easily cause the elderly's body to fall and bump into the bed when they slide. Since the elderly's physical functions are relatively weak, the downward slide may cause the elderly's back to be bruised. Therefore, it is very necessary to design a reasonable turning device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problems in the prior art, and provide a turning device for elderly care, which can better assist the elderly in turning over and prevent the elderly from sliding due to their body weight during turning, which may cause harm to the elderly.

[0005] The present invention provides a turning device for the care of the elderly, which includes a bed frame and a set of turning components arranged in the bed frame for assisting the elderly to turn over. Each of the turning components includes a turning board and a driving component for driving the turning board to rotate. One side of each of the two turning boards close to each other is rotatably connected to the bed frame. A support component is arranged on each of the turning boards. A through groove is formed in the turning board in the vertical direction. The support component includes a support block and a lifting rod. The support block is slidably arranged in the through groove, and the lifting rod is vertically and fixedly connected to the bottom of the support block. A connecting component is arranged under each of the turning boards. The connecting component includes a first wedge block, a second wedge block and a connecting rod. The first wedge block is fixedly connected to the bottom of the lifting rod. The first wedge block fits with the second wedge block. One side of the second wedge block is fixedly connected to the connecting rod. The connecting rod under one side turning board is connected to the corresponding driving component of the other side turning board.

[0006] Preferably, the driving component includes a pair of horizontally arranged support grooves. The pair of support grooves are arranged along the width direction of the bed frame. Sliders are slidably arranged in each of the pair of support grooves. The top of the slider is hinged to the bottom of the turning board through a hinge rod. One end of the slider is fixedly connected to a driving rod. One end of the driving rod slidably penetrates through the bed frame and is fixedly connected to a horizontal thruster. The connecting rod is fixedly connected to the slider. When the slider moves, the second wedge block will be moved through the connecting rod. When the second wedge block moves, the first wedge block will move upward so as to push the support block out of the through groove.

[0007] Preferably, a plurality of grooves are formed on one side of the support block close to the edge of the bed. A flexible pad is sleeved outside the support block, and the top corners of the support block are smoothly transitioned through a radian angle.

[0008] Preferably, a cavity is arranged in the turning board. A limiting plate is fixedly sleeved outside the support block. The limiting plate is located in the cavity. The limiting plate is set as a magnetic plate. A magnet is fixedly arranged at the top inside of the cavity. When the magnetic plate adsorbs to the magnet, it is sufficient to carry and support the position of the support block.

[0009] Preferably, a first support plate is vertically and fixedly connected to the bottom of the bed frame. The connecting rod horizontally slides through the first support plate.

[0010] Preferably, a massage component is provided inside the turning board. The massage component includes a moving rod, a massage head, a contact plate, a return spring, and an airbag. A plurality of the moving rods are provided. A plurality of through holes are correspondingly provided on the turning board. The plurality of moving rods are slidably arranged through the through holes one by one. One ends of the plurality of moving rods are fixedly connected with the massage heads respectively, and the other ends are fixedly connected with the contact plates respectively. Return springs are sleeved on the plurality of moving rods. One end of each return spring is fixedly connected with the turning board, and the other end is fixedly connected with the contact plate. When the airbag expands, it is used to squeeze the contact plate to push out the massage head through the moving rod to massage the back of the elderly.

[0011] Preferably, a sealing box is provided inside the cavity. The sealing box seals the massage component. An air supply component for supplying gas to the airbag is provided inside the sealing box. The air supply component includes an inflation pipe, a pushing block, a push rod, and an air supply pipe. The inflation pipe is horizontally arranged in the support groove. The pushing block is slidably embedded in the support groove. The push rod is horizontally arranged. One end of the push rod is fixedly connected with the pushing block, and the other end is fixedly connected with the slider. The inside of the hinge shaft is hollow. One end of the air supply pipe is connected to the air outlet of the inflation pipe, and the other end is connected and communicated with the hinge shaft. An air outlet hole is provided in the cavity where the hinge shaft is located. The air inlet pipe of the airbag is communicated with the air outlet hole.

[0012] Preferably, the bed frame includes a bedstead and four support columns installed at the bottom of the bedstead. The support column is composed of a first support rod and a second support rod. The second support rod is slidably arranged inside the first support rod. A brake wheel is provided at the bottom of the first support rod. A horizontally arranged second support plate is provided. The second support plate is fixedly connected with the first support rod. A cylinder is vertically and fixedly connected to the middle position of the second support plate. The advancing end of the cylinder is fixedly connected with a connecting plate. The connecting plate is fixedly connected with the second support rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: when the elderly lying on the turning board needs to be turned over, the turning board is driven by an external force and rotates with the assistance of a hinge shaft, giving a thrust to one side of the elderly's body. At this time, the elderly's body will tilt toward the turning board that is turning over on the other side. While the turning board is turning over, the support block embedded in the turning board rises upward under the action of the lifting rod, and the support block is pushed out of the turning board to provide a support point for the elderly who are turning over. The elderly can hold the support block tightly with their palms and cooperate with the turning board to slowly turn over. The elderly person can flip over after the flip is completed, and the support block can also play a role of temporary support. Because the elderly person is prone to unstable center of gravity and will fall to the side when lying on his side, in the present invention, the elderly person only needs to cling to the support block with his arms to temporarily support his body. The above scheme can assist the elderly person to turn over better and safely, and prevent the elderly person from slipping due to his body weight, which will not only affect the elderly person's turning over, but also cause the elderly person's body to fall and hit the bed when he slips. Because the elderly person's body function is weak, the elderly person's back may be injured when falling.

[0014] The present invention cleverly utilizes the fit between the first wedge block and the second wedge block. When the slider is pushed by the horizontal thruster, the turning plate is turned around the hinge axis under the action of the hinge rod. At the same time, the second wedge block is moved toward the side of the first wedge block through the provided connecting rod. As the slider moves, the first wedge block moves upward under the push of the second wedge block, thereby pushing the support block out of the turning plate. The turning assembly 3 is cleverly combined with the support assembly so that the two can operate synchronously. The design is clever and cost-effective.

[0015] The present invention takes into account that the elderly will feel uncomfortable due to insufficient blood circulation in the back when lying on the hospital bed for a long time. Therefore, a massage component is arranged in the turning board, and the massage component is powered by an air supply component. When the arranged air bag is inflated, the arranged abutment plate is pressed, so that the arranged moving rod is pushed to push the massage head out of the turning board to massage the elderly's back, thereby alleviating the discomfort of the elderly's back.

The drawings in this invention are not strictly drawn to actual scale, and the specific dimensions and quantities of each structure can be determined according to actual needs. The drawings described in this invention are only schematic diagrams of the structures.

[0026] The turning-over device for the care of the elderly provided by the present invention, as Figures 1 to 4 shown, the present invention provides a turning-over device for the care of the elderly, including a bed frame 1 and a set of turning-over components 3 arranged inside the bed frame 1 for assisting the elderly to turn over. Each turning-over component 3 includes a turning-over plate 31 and a driving component for driving the turning-over plate 31 to rotate. One side of the two turning-over plates 31 close to each other is rotatably connected to the bed frame 1. A support component 4 is arranged on each turning-over plate 31. A through groove 41 is formed in the turning-over plate 31 in the vertical direction. The support component 4 includes a support block 42 and a lifting rod 43. The support block 42 is slidably arranged in the through groove 41, and the lifting rod 43 is vertically and fixedly connected to the bottom of the support block 42. A connecting component is arranged under each turning-over plate 31. The connecting component includes a first wedge block 5, a second wedge block 6 and a connecting rod 7. The first wedge block 5 is fixedly connected to the bottom of the lifting rod 43. The first wedge block 5 fits with the second wedge block 6. One side of the second wedge block 6 is fixedly connected to the connecting rod 7. The connecting rod 7 under one side of the turning-over plate 31 is connected to the driving component corresponding to the other turning-over plate 31.

[0027] When the elderly person lying on the turning board 31 needs to turn over, the turning board 31 is driven by an external force and assisted by the hinge shaft 32 to rotate, giving a thrust to one side of the elderly person's body, and the elderly person's body will tilt to the turning board 31 on the other side. When the turning board 31 is turned over, the support block 42 embedded in the turning board 31 rises upward under the action of the lifting rod 43, and the support block 42 is pushed out from the turning board 31 to provide a support point for the elderly person who is turning over. The elderly person can slowly turn over by holding the support block 42 with the turning board 31 by the palm of his hand. After the turning over is completed, the support block 42 can also play a temporary support role. Because the elderly person is prone to unstable center of gravity and will tilt to the side when lying on his side, the elderly person only needs to cling to the support block 42 with his arms to temporarily support his body. The above scheme helps the elderly person to turn over better and more safely, and prevents slippage due to the weight of the elderly person's body. The present invention ingeniously utilizes the fit between the first wedge block 5 and the second wedge block 6. When the slider 33 is pushed by the horizontal propeller 36, the turning plate 31 is turned around the hinge shaft 32 under the action of the hinge rod 34. At the same time, the second wedge block 6 is moved toward the side of the first wedge block 5 through the provided connecting rod 7. As the slider 33 moves, the first wedge block 5 is pushed upward by the second wedge block 6, thereby pushing the support block 42 out of the turning plate 31. The turning assembly 3 and the support assembly 4 are ingeniously combined to make the two run synchronously. The design is ingenious and saves energy.

[0028] Preferably, Figures 1 to 4 As shown, the driving assembly includes a pair of horizontally arranged support grooves 37, and the pair of support grooves 37 are arranged along the width direction of the bed frame 1. Sliders 33 are slidably arranged in the pair of support grooves 37. The top of the slide block 33 is hinged to the bottom of the turning board 31 through a hinge rod 34. One end of the slide block 33 is fixedly connected to a driving rod 35. One end of the driving rod 35 slides through the bed frame 1 and is fixedly connected to a horizontal propeller 36. The connecting rod 7 is fixedly connected to the slide block 33. When the slide block 33 moves, the second wedge block 6 will be moved through the connecting rod 7. When the second wedge block 6 moves, the first wedge block 5 will move up, thereby pushing the support block 42 out of the through groove 41.

[0029] When the elderly lying on the turning board 31 needs to be turned over, the driving rod 35 is pushed by the horizontal propeller 36, and the driving rod 35 pushes the slider 33. Since the slider 33 and the turning board 31 are hinged by the hinge rod 34, the turning board 31 rotates around the hinge shaft 32 as the slider 33 moves, and then the force is applied to one side of the elderly's body, thereby realizing the change of the turning position of the elderly's body.

[0030] Further, such asFigure 1 As shown, a plurality of grooves 8 are formed on one side of the support block 42 close to the edge of the bed frame 1. A flexible pad is sleeved outside the support block 42, and the top corners of the support block 42 are smoothly transitioned through arc angles.

[0031] In the present invention, a plurality of grooves 8 are formed on one side of the support block 42, which is convenient for the elderly to grasp with their hands. A flexible pad is arranged outside the support block 42 to prevent the rigid support block 42 from bumping the elderly. The top corners of the support block 42 are smoothly transitioned through arc angles. On the one hand, it makes the elderly more comfortable when holding the support block 42, and on the other hand, it prevents the edges and corners of the support block 42 from bumping the elderly.

[0032] Furthermore, as Figure 6 shown, a cavity is arranged inside the turnover plate 31. A limiting plate 9 is fixedly sleeved outside the support block 42. The limiting plate 9 is located inside the cavity. The limiting plate 9 is set as a magnetic plate. A magnet 10 is fixedly arranged at the top inside the cavity. When the magnetic plate is adsorbed to the magnet 10, it is sufficient to support and carry the position of the support block 42. A first support plate 11 is vertically and fixedly connected to the bottom of the bed frame 1. The connecting rod 7 horizontally slides through the first support plate 11.

[0033] In the present invention, the limiting plate 9 is sleeved on the support block 42 to prevent the support block 42 from sliding out of the through groove 41. When the first wedge block 5 moves upward to push the lifting rod 43, the sleeved limiting plate 9 will move together. When the limiting plate 9 is tightly attracted to the set magnet 10, the support block 42 moves to the highest position. At this time, the turnover work of the elderly is completed. After the turnover work of the elderly is completed, the slider 33 is pulled back through the horizontal thruster 36 to level the rotating turnover plate 31 again. Although there is no support at the bottom of the first wedge block 5 after the second wedge block 6 moves, because the limiting plate 9 is set as a magnetic plate, under the action of the magnet 10, it still provides support force for the support block 42, playing a role of temporary support to prevent the elderly from being prone to unstable center of gravity and toppling to the side when lying on their sides.

[0034] Furthermore, as Figures 5 to 6As shown in the figure, a massage component 12 is provided inside the turning board 31. The massage component 12 includes a moving rod 121, a massage head 122, an abutting plate 123, a return spring 124 and an airbag 125. A number of moving rods 121 are provided. A number of through holes are correspondingly provided on the turning board 31. The number of moving rods 121 are slidably arranged in the through holes one by one. One ends of the number of moving rods 121 are fixedly connected with massage heads 122, and the other ends are fixedly connected with abutting plates 123. Return springs 124 are sleeved on the number of moving rods 121. One end of the return spring 124 is fixedly connected with the turning board 31, and the other end is fixedly connected with the abutting plate 123. When the airbag 125 expands, it is used to squeeze the abutting plate 123 to push out the massage head 122 through the moving rod 121 to massage the back of the elderly. A sealing box 13 is provided in the cavity. The sealing box 13 seals the massage component 12. An air supply component 14 for supplying gas to the airbag 125 is provided in the sealing box 13. The air supply component 14 includes an inflation pipe 141, a push block 142, a push rod 143 and an air supply pipe 144. The inflation pipe 141 is horizontally arranged in the support groove 37. The push block 142 is slidably embedded in the support groove 37. One end of the horizontally arranged push rod 143 is fixedly connected with the push block 142, and the other end is fixedly connected with the slider 33. The turning board 31 is hinged to the bed frame 1 through a hinge shaft 32. The inside of the hinge shaft 32 is hollow. One end of the air supply pipe 144 is connected to the air outlet of the inflation pipe 141, and the other end is connected and communicated with the hinge shaft 32. An air outlet hole is provided in the hinge shaft 32 placed in the cavity. The airbag 125 is communicated with the air outlet hole through an air inlet pipe 145.

[0035] In the present invention, since the elderly lie on the hospital bed for a long time and the blood circulation in the back is insufficient, they will feel uncomfortable. Therefore, a massage component 12 is provided in the turning board 31. When the provided airbag 125 expands, it will push the provided abutting plate 123, so as to push out the massage head 122 from the turning board 31 through the moving rod 121 to massage the back of the elderly, relieving the discomfort of the elderly's back. An air supply component 14 is also provided in the present invention, and the power source of the air supply component 14 is associated with the turning component 3. When the slider 33 is pushed by the horizontal thruster 36 to rotate the turning board 31, the slider 33 will push the provided push rod 143, and the push rod 143 will push the provided push block 142, so as to press the air in the inflation pipe 141 into the hinge shaft 32 through the air supply pipe 144, and convey the gas to the airbag 125 through the air outlet hole provided on the hinge shaft 32 through the air inlet pipe 145, causing the airbag 125 to expand, skillfully synchronizing the power of the massage component 12 with the turning component 3, and massaging the back of the elderly while turning the elderly.

[0036] Further, as Figure 7As shown in the figure, the bed frame 1 includes a bedstead and four support columns 15 installed at the bottom of the bedstead. The support column 15 is composed of a first rod 151 and a second rod 152. The second rod 152 is slidably arranged inside the first rod 151. A braking wheel is provided at the bottom of the first rod 151. In addition, a horizontally arranged second support plate 16 is provided. The second support plate 16 is fixedly connected to the first rod 151. A cylinder 17 is vertically and fixedly connected to the middle position of the second support plate 16. A connecting plate 18 is fixedly connected to the advancing end of the cylinder 17. The connecting plate 18 is fixedly connected to the second rod 152.

[0037] The braking wheel provided at the bottom of the first rod 151 facilitates adjusting the position of the set bed frame 1 at any time. By setting the cylinder 17 to push the connecting plate 18, at this time the connecting plate 18 will drive the second rod 152 to move upward inside the first rod 151 to lift the bed frame 1 to a suitable height. Considering that the elderly are often inconvenient in their bodies, the bed frame 1 of the present invention is set to be liftable, which is convenient for timely adjusting the height of the bed frame 1 according to the situation.

[0038] The usage method of the turning device for the elderly care of the present invention is as follows: The elderly lie flat on a pair of turning plates 31, and the body is located in the middle of the bed frame 1. Generally, one half of the body is on one turning plate 31, and the other half is on the other turning plate 31. When it is necessary to turn the body of the elderly, at this time, only need to push the set driving rod 35 through the set horizontal thruster 36. At this time, the push rod will push the set slider 33. Since the slider 33 is hinged to the turning plate 31 through the set hinge rod 34, as the slider 33 moves, the turning plate 31 will rotate around the hinge shaft 32, and then the acting force will act on one side of the elderly's body, realizing the change of the turning position of the elderly's body.

[0039] When the slider 33 slides in the support groove 37, it will push the second wedge block 6 through the connecting rod 7. When the second wedge block 6 fits with the first wedge block 5, as the slider 33 further moves, the first wedge block 5 will move upward under the push of the second wedge block 6, thereby pushing the lifting rod 43. The support block 42 is pushed out of the turning plate 31 through the lifting rod 43, which cleverly combines the turning assembly 3 and the support assembly 4, so that the two operate synchronously.

[0040] Meanwhile, the moving slider 33 also pushes the push rod 143, which in turn pushes the set push block 142, thereby pressing the air in the inflatable tube 141 through the supply tube 144 into the hinge shaft 32. The gas is then transported through the air outlet provided on the hinge shaft 32 to the airbag 125 through the intake pipe 145, causing the airbag 125 to expand. When the airbag 125 expands, it pushes the set abutment plate 123, and then the massage head 122 is pushed out of the turning plate 31 through the moving rod 121 to massage the back of the elderly, alleviating the discomfort in the elderly's back.

[0041] When the first wedge block 5 moves upward to push the lifting rod 43, the sleeved limit plate 9 moves along with it. When the limit plate 9 is attracted tightly to the set magnet 10, the support block 42 moves to the highest position, and at this time, the turning work of the elderly is completed. After the turning work of the elderly is completed, the slider 33 is pulled back by the horizontal thruster 36 to level the rotating turning plate 31 again. Although there is no support at the bottom of the first wedge block 5 after the second wedge block 6 moves, since the limit plate 9 is a magnetic plate, it still provides support for the support block 42 under the action of the magnet 10, playing a role of temporary support to prevent the elderly from losing balance and toppling to the side when lying on their side. One turning action is completed. When the elderly need to lie flat, just make the turning plate 31 turn again to bear the back of the elderly, and the elderly move slowly along with the turning plate 31 to complete lying flat.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
