Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of nursing beds, and particularly relates to an elderly care bed with an auxiliary turning function. Background Art
[0002] With the acceleration of the aging process of the population, the demand for long-term care services among the disabled and semi-disabled elderly groups is increasing day by day. Among them, the body position care of bedridden elderly people is an important part of daily care. Most traditional nursing beds use a rigid structure to achieve the turning function, and directly push the human body to tilt through mechanical devices, which is likely to cause the concentrated force on bones and joints, and may cause the risk of pressure sores in the long term. In recent years, the flexible turning technology has gradually become a research hotspot. It drives the user to slowly turn the body through the continuous deformation of the flexible material on the bed surface. For example, a movable flexible fabric layer is arranged on the bed, and the fabric layer is driven by a motor to move horizontally, so that the human body slides with the fabric to complete the turning action.
[0003] For example, in the prior art (patent application with publication number CN110115666B and patent name "A Flexible Turner"), the turning cloth is laid horizontally on the bed, and the patient lies longitudinally on the turning cloth. Single pulleys and double pulleys are respectively arranged at both ends of the upper part of the frame. The frame is provided with a zip to horizontally tighten the frame on both sides of the bed. The winder is arranged on the side of the frame. The long rope and the short rope are wound and released by the winder, and the turning cloth is pulled to rise on one side or at the head through the double pulley and the single pulley, so as to push the patient to turn over or sit up from both sides respectively. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art
[0004] In the above patent, the user can turn over by the movement of the flexible cloth subsequently. However, after turning over, since the user's arms will always be pressed under the body, it will cause blood circulation obstruction, resulting in problems such as limb numbness and nerve compression. And when lying face down after turning over, it will cause the user to have difficulty breathing. Therefore, this problem not only affects the use comfort, but may also induce other problems. Summary of the Invention

Teeth are provided on the surface of the push arms, and the teeth are meshed with a first gear. At the same time, a first motor is connected above the first gear.
[0007] Preferably, lifting cylinders are respectively fixed at four places on the outer surface of the bed frame. The interior of the lifting cylinder is provided with a hollow structure, and a hydraulic cylinder is fixed inside it.

[0010] Preferably, the interior of the support seat is provided with a hollow structure. A second motor is fixed on one side of the inner bottom surface of the support seat. A first rotating shaft is connected to the power output end of the second motor. Eccentric blocks for the rotation and vibration of the first rotating shaft are respectively fixed on both sides of the outer circumferential surface of the first rotating shaft.
[0011] Preferably, a reciprocating groove extends from the central part of the outer circumferential surface of the first rotating shaft to both sides. A sliding sleeve is sleeved on the outer circumferential surface of the reciprocating groove, and reciprocating holes are penetrated through both ends of the sliding sleeve.
[0012] Preferably, a moving arm extends from the outer circumferential surface of the sliding sleeve towards the support seat. At the same time, pressure rods are respectively fixed at both ends of the outer surface of the moving arm, and pressure pipes are respectively fixed on both sides of the inner cavity bottom surface of the support seat.
[0013] Preferably, an air pipe that is not interconnected in the middle is sleeved between the two pressure pipes. At the same time, a flexible film covers the surface of the support seat, and the flexible film is communicated with the air pipe through a communicating pipe at the bottom.
[0014] Preferably, an expansion groove is opened downward on the surface of the flexible film. The expansion groove is communicated with the air pipe through a through hole, and an expansion film covers the opening of the expansion groove.
[0015] Preferably, an exhaust hole is opened on one side of the outer surface of the support seat, an air inlet hole is opened at the other end of the support seat opposite to the exhaust hole, and crown gears are respectively fixed on both sides of the outer circumferential surface of the first rotating shaft.

[0016] One kind of nursing bed with an auxiliary turning function of the present invention has the following advantages:
[0017] 1. This elderly care bed with an auxiliary turning over function, while the flexible cloth is constantly moving, once the motor on one side is running, the push arm can be continuously moved, and then the support seat surface of the pressure surface is turned toward the user and contacts the user.

[0019] 3. This elderly care bed with an auxiliary turning over function, when the motor 2 is running, the rotating shaft 1 at the output end of the motor 2 continuously rotates at a high speed, and then the sliding sleeve can continuously move back and forth, and then the gas passes through the through hole to expand the expansion membrane on one side of the flexible membrane surface, while the expansion membrane on the other side shrinks due to the pressure rod extracting the gas inside the pressure tube, so that the user lying on the support seat can further achieve a massage effect as the expansion and shrinkage of the expansion membrane.

Detailed implementation manners
[0035] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0036] As Figures 1-6As shown in the figure, a nursing bed with an auxiliary turning function according to the present invention is composed of a bed frame 1. At the four corners of the bottom of the bed frame 1, rollers are respectively connected. Through these rollers, the nursing bed can be pushed and displaced. At the same time, baffles 11 are respectively fixed on both sides of the bed frame 1 when it is lying flat. These baffles 11 can prevent the user from falling. Angle plates 12 that can be turned at an angle are respectively connected to the surface of the lying area of the bed frame 1. The bottom surface of the angle plate 12 is pushed by an electric push rod. This is prior art and will not be elaborated here. The bedding for lying flat is laid on the surface of the angle plate 12.
[0037] Lifting cylinders 2 are respectively fixed at four places on the outer surface of the bed frame 1. The inside of the lifting cylinder 2 is arranged in a hollow structure, and a hydraulic cylinder 22 is fixed inside it. One end of the lifting rod 21 for telescopic displacement is placed at the power output end of the hydraulic cylinder 22. After the hydraulic cylinder 22 operates, the upper lifting rod 21 can be lifted and lowered. A motor sleeve 211 is sleeved on the top of the lifting rod 21. At the same time, the opposite surfaces of the two motor sleeves 211 are open, and a winding motor 32 is fixed inside. A winding shaft 3 is connected between the two winding motors 32, and the winding shaft 3 is respectively arranged on both sides of the bed frame 1. Flexible cloths 31 are respectively wound around the outer circumferential surfaces of the two winding shafts 3, and the flexible cloths 31 are placed above the angle plates 12. Therefore, when the user needs to turn over, the hydraulic cylinders 22 on both sides of the bed frame 1 can operate at this time. Then, by rising with the height difference of the lifting rods 21, the flexible cloths 31 can be in a tilted state, and the winding motors 32 above the lifting rods 21 at the high position and the low position keep running, so that the flexible cloths 31 can move. At this time, the user lying on the upper side can turn over.
[0038] As Figures 5-6 shown in the figure, a rotatable rotating seat 212 is coaxially arranged at one end of the motor sleeve 211. An expansion hole 213 for the telescopic movement of the push arm 41 is penetrated through the outer circumferential surface of the rotating seat 212. At the same time, teeth 45 are arranged on the surface of the push arm 41, and a first gear 215 is meshed and connected on one side of the teeth 45. The rotation of the first gear 215 is driven by a first motor 214 fixedly connected above the rotating seat 212. Therefore, after the first motor 214 operates, the first gear 215 can rotate. After the first gear 215 rotates, it can drive the push arm 41 to move telescopically along the expansion hole 213.
[0039] A support base 4 is connected between the free ends of the two push arms 41, and the support base 4 is arranged in a triangular structure. The two ends of the support base 4 are movably connected to the free ends of the push arms 41, and then the support base 4 can rotate with the connection of the push arms 41 as the axis. Therefore, when the user needs to turn over, the flexible cloth 31 is constantly moving, and then the motor 214 on one side is running, so that the push arm 41 can be continuously moved, and then the surface of the support base 4 on the pressure surface is turned toward the user and contacts the user. Therefore, after turning over, the support base 4 is cushioned under the user, thereby relieving the force of the body pressing the arm and preventing numbness, and the support base 4 located on the back of the user is against the back, thereby preventing the user from falling when turning over.
[0040] like Figure 7 As shown, the interior of the support seat 4 is a hollow structure, and a motor 2 6 is fixed on one side of the bottom surface of the interior thereof, and a rotating shaft 1 61 is connected to the power output end of the motor 2 6, and eccentric blocks 611 for rotating and vibrating the rotating shaft 1 61 are respectively fixed on both sides of the outer circumference of the rotating shaft 1 61. Therefore, after the user turns over and the center of the back part lies on the top of the support seat 4, the motor 2 6 inside the support seat 4 is operated, and after the motor 2 6 is operated, the rotating shaft 1 61 is continuously rotated, and after the rotating shaft 1 61 rotates, vibration can be generated through the eccentric block 611, thereby providing a certain degree of vibration relaxation to the person who uses it for a long time.
[0041] like Figures 7-13 As shown, a reciprocating groove 612 extends to both sides from the central part of the outer circumference of the rotating shaft 1 61. The reciprocating groove 612 is composed of two thread grooves with the same pitch and opposite rotation direction, and is connected at both ends by a transition curve. At the same time, a sliding sleeve 8 is sleeved on the outer circumference of the reciprocating groove 612, and reciprocating holes 85 are penetrated at both ends of the sliding sleeve 8. An insert is connected to the inner ring wall of the reciprocating hole 85, and one end of the insert extends to the reciprocating groove 612. As the rotating shaft 1 61 rotates, the sliding sleeve 8 can continuously reciprocate along the length direction of the reciprocating groove 612.
[0042] A moving arm 81 extends from the outer peripheral surface of the sliding sleeve 8 towards the direction with a smaller included angle with the support base 4. At the same time, pressure rods 82 are respectively fixed at both ends of the outer surface of the moving arm 81. Pressure tubes 5 are respectively fixed on both sides of the inner cavity bottom surface of the support base 4. The inside of the pressure tube 5 is long and hollow, and one end of the pressure rod 82 extends into the inside of the pressure tube 5. A non-interconnected trachea 422 is sleeved between the two pressure tubes 5. At the same time, a flexible membrane 42 covers the surface of the support base 4. The bottom of the flexible membrane 42 is communicated with the trachea 422 through a connecting pipe 423. An expansion groove 424 is opened downward on the surface of the flexible membrane 42. The expansion groove 424 is communicated with the trachea 422 through a through hole 425. An expansion membrane 421 covers the opening of the expansion groove 424. Therefore, when the second motor 6 operates, the rotating shaft 61 at the output end of the second motor 6 rotates continuously at a high speed. Subsequently, the sliding sleeve 8 can reciprocate continuously. When the sliding sleeve 8 reciprocates, the pressure rod 82 connected to the sliding sleeve 8 can continuously squeeze into the inside of the pressure tube 5 on the moving side. Since the inside of the trachea 422 is not interconnected in the center, after the pressure tube 5 on one side pressurizes the gas, the gas immediately enables the expansion membrane 421 on one side of the surface of the flexible membrane 42 to expand through the through hole 425, while the expansion membrane 421 on the other side retracts because the pressure rod 82 extracts the gas from the inside of the pressure tube 5. Thus, the user lying on the support base 4 can be further massaged as the expansion membrane 421 expands and retracts.
[0043] As Figures 7-10 shown, an exhaust hole 44 is opened at the acute angle of the support base 4, and an intake hole 43 is opened at the other end of the support base 4 opposite to the exhaust hole 44. Crown gears 63 are respectively fixed on both sides of the outer peripheral surface of the rotating shaft 61. A bracket is fixed on the inner cavity bottom surface of the support base 4. A second gear 631 is meshed and connected to one side of the crown gear 63. An impeller 632 is fixed on the surface of the second gear 631 facing the exhaust hole 44. One end of the rotation axis of the impeller 632 penetrates through the bracket, thereby providing a rotational support force for it. Therefore, when the rotating shaft 61 rotates through the second motor 6, the crown gear 63 on the rotating shaft 61 can drive the second gear 631 at this time. After the second gear 631 rotates, the impeller 632 can be rotated. Subsequently, the airflow discharged by the impeller 632 can be discharged from the exhaust hole 44, thereby performing a certain ventilation treatment for the user.
[0044] As Figure 7 and Figure 13As shown, when the user lies flat on the bed for a long time and turns over, the existing bed cannot perform a certain massage treatment on the lying chest area during turning over. A moving groove 46 is opened downward on the surface of the support base 4. An expansion cylinder 62 extends upward from the top of the outer peripheral surface of the sliding sleeve 8. At the same time, it is hollow and open downward from the top of the expansion cylinder 62. A reciprocating screw rod 83 is coaxially connected to the bottom of the inner cavity of the expansion cylinder 62. A top rod 7 is sleeved above the outer peripheral surface of the reciprocating screw rod 83. A first reciprocating hole 73 opened upward on the bottom surface of the top rod 7 is sleeved on the reciprocating screw rod 83. And an inlay block is also provided on the inner ring wall of the first reciprocating hole 73. One end of the inlay block extends into the path of the reciprocating screw rod 83. Therefore, after the reciprocating screw rod 83 rotates, the top rod 7 sleeved above can continuously expand and contract and displace.
[0045] Limiting rods 72 are respectively fixed on the outer peripheral surface of the top rod 7. One end of the limiting rod 72 extends into a limiting groove 622 opened downward at the top of the expansion cylinder 62. Through the limiting rod 72, the top rod 7 can be lifted and lowered along the vertical direction. A massage ball 71 is also fixed on the top of the top rod 7. The surface of the massage ball 71 abuts against the bottom surface of the flexible film 42. A third gear 84 is fixed below the outer peripheral surface of the reciprocating screw rod 83 inside the expansion cylinder 62. A rack groove 621 is opened on one side of the outer peripheral surface of the expansion cylinder 62. At the same time, a rack 9 meshed with the third gear 84 is arranged at the opening of the rack groove 621. The two ends above the rack 9 are connected to the top of the inner cavity of the support base 4 through connecting columns. Therefore, when the rotating shaft 61 rotates to make the sliding sleeve 8 continuously reciprocate, at this time, the expansion cylinder 62 on the sliding sleeve 8 also moves together. When the sliding sleeve 8 moves, the third gear 84 inside the sliding sleeve 8 meshes with the rack 9. Therefore, the reciprocating screw rod 83 can continuously rotate. After the reciprocating screw rod 83 rotates, the top rod 7 thereon continuously moves up and down. After the top rod 7 moves, the user can be continuously massaged through the massage ball 71 above.
[0046] Working principle of an elderly care bed with an auxiliary turning-over function: When the user needs to turn over, the hydraulic cylinders 22 on both sides of the bed frame 1 can operate at this time. Subsequently, through the height difference of the lifting rods 21 rising, the flexible cloth 31 can be made to be in a somewhat inclined state. And the winding motors 32 above the lifting rods 21 at the high position and the low position continuously operate, so that the flexible cloth 31 can move. At this time, the user lying flat above can turn over;
[0047] While the flexible cloth 31 is continuously moving, the motor 214 on one side is running, so that the push arm 41 is continuously moving, and then the surface of the support seat 4 on the compression surface is turned toward the user, and the surface is against the user. Therefore, after turning over, the support seat 4 is cushioned under the user, thereby relieving the force of the body pressing the arm and preventing numbness, and the support seat 4 located on the back of the user is against the back, thereby preventing the user from falling when turning over.
[0048] After the user turns over and the center of the back part lies on the support seat 4, the motor 2 6 inside the support seat 4 starts to operate, and the rotation shaft 1 61 is continuously rotated after the motor 2 6 is operated. After the rotation shaft 1 61 rotates, vibration is generated through the eccentric block 611, thereby providing a certain degree of vibration relaxation to the person who has been using the device for a long time;
[0049] When the motor 2 6 is running, the rotating shaft 1 61 at the output end of the motor 2 6 continuously rotates at a high speed, and then the sliding sleeve 8 can continuously reciprocate. When the sliding sleeve 8 reciprocates, the pressurizing rod 82 connected to the sliding sleeve 8 can continuously squeeze the inside of the pressurizing tube 5 on the moving side. Since the inner centers of the air pipe 422 are not interconnected, after the pressurizing tube 5 on one side pressurizes the gas, the gas immediately passes through the through hole 425 to expand the expansion membrane 421 on one side of the surface of the flexible membrane 42, while the expansion membrane 421 on the other side shrinks because the pressurizing rod 82 extracts the gas inside the pressurizing tube 5, so that the user lying on the support seat 4 can further achieve a massage effect as the expansion membrane 421 expands and shrinks;
[0050] When the rotating shaft 1 61 is rotated by the motor 2 6, the crown gear 63 on the rotating shaft 1 61 can drive the gear 2 631, and the impeller 632 can be rotated as the gear 2 631 rotates, and then the airflow discharged by the impeller 632 can be discharged from the exhaust hole 44, thereby providing a certain ventilation treatment for the user;
[0051] Finally, when the rotating shaft 1 61 rotates to make the sliding sleeve 8 continuously reciprocate, the telescopic cylinder 62 on the sliding sleeve 8 moves together. When the sliding sleeve 8 moves, the gear 3 84 inside the sliding sleeve 8 is meshed with the rack 9, so that the reciprocating screw 83 can rotate continuously. As the reciprocating screw 83 rotates, the push rod 7 on it continuously moves up and down. After the push rod 7 moves, the massage ball 71 above can continuously massage the user.
[0052] It should be noted that the specific models and specifications of the hydraulic cylinder 22, motor 1 214, winding motor 32 and motor 2 6 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
[0053] The power supply and its principle of the hydraulic cylinder 22, the first motor 214, the winding motor 32 and the second motor 6 are clear to those skilled in the art and will not be described in detail herein.
