[0032] Embodiment 1
[0033] As Figures 1 to 9As shown in the figure, the present invention provides a combined assisted convalescent bed, which includes a base 1. A moving device is arranged on the base 1, and the base 1 provides support for the moving device. The moving device includes two pairs of moving wheels 2. Each pair of moving wheels 2 is connected by a rotating rod 3, and the two pairs of moving wheels 2 are connected by a connecting plate 4, which facilitates the combined movement of the four moving wheels 2. First chutes 101 are opened on both sides of the base 1, and a second chute 102 is opened on the base 1 between the two first chutes 101. The four moving wheels 2 are respectively located in the two first chutes 101 in pairs, and the first chutes 101 can limit the moving directions of the four moving wheels 2. The middle parts of the two connecting plates 4 are connected by a rotating shaft, and a gear 8 and a worm gear 12 are arranged on the rotating shaft. The gear 8 and the worm gear 12 rotate coaxially. The gear 8 meshes with a first toothed plate 7, and the first toothed plate 7 is installed on the base 1 and fixedly connected in the second chute 102. When the gear 8 rotates, it meshes with the first toothed plate 7 to make the gear 8 reciprocate along the first toothed plate 7. The worm gear 12 is connected to a driving device, and the driving device can drive the worm gear 12 to rotate. Since the worm gear 12 and the gear 8 are coaxial, the gear 8 rotates.
[0034] The moving device is connected to the driving device, and the driving device provides power for the moving device. The driving device includes a motor, the motor is connected to a worm 11, and the worm 11 meshes with the worm gear 12. When the motor is started, the motor drives the worm 11 to rotate, and the rotation of the worm 11 drives the worm gear 12 to rotate, so that the gear 8 reciprocates on the first toothed plate 7. Both ends of the worm 11 penetrate through fixing blocks 10, and the fixing blocks 10 are installed on one side of a second toothed plate 13. The two fixing blocks 10 provide support for the worm 11 and the motor. Both ends of the rotating rod 3 penetrate through a U-shaped rod 9 respectively, and a bearing is arranged between the rotating rod 3 and the U-shaped rod 9. The rotating rod 3 can provide support for the U-shaped rod 9. A third chute 91 is provided on the U-shaped rod 9, and the second toothed plate 13 is located in the third chute 91. A through groove 92 is opened at the bottom of the third chute 91, and the through groove 92 corresponds to the gear 8. The gear 8 meshes with the second toothed plate 13, and the rotation of the gear 8 can drive the second toothed plate 13 to reciprocate along the third chute 91.
[0035] The top of the mobile device is connected to the adjusting device and the first bed board 6. The mobile device can drive the adjusting device and the first bed board 6 to move. At the top of the middle part of the connecting plate 4, a support rod 5 is fixedly connected. The top of the support rod 5 is connected to the first bed board 6. The support rod 5 connects the mobile device and the first bed board 6, facilitating the movement of the first bed board 6 with the mobile device, and the support rod 5 provides support for the first bed board 6. At both ends of the first bed board 6, a second bed board 14 and a third bed board 15 are respectively hinged. The bottoms of the second bed board 14 and the third bed board 15 are connected to the adjusting device. The adjusting device can adjust the angles between the second bed board 14 and the first bed board 6, and between the third bed board 15 and the first bed board 6. The adjusting device includes a cylindrical rod 16. The bottom of the cylindrical rod 16 is fixedly installed on the second toothed plate 13. The movement of the second toothed plate 13 can drive the movement of the cylindrical rod 16.
[0036] A sleeve rod 17 is sleeved on the cylindrical rod 16. The sleeve rod 17 can move up and down along the cylindrical rod 16. At the top of the sleeve rod 17, connecting rods 18 are symmetrically arranged. The ends of the connecting rods 18 are fixedly connected to the middle part of the adjusting rod 19. Both ends of the adjusting rod 19 are hinged to the bottom ends of the fixed rods 20. Both ends of the adjusting rod 19 are fixedly connected to the armrest frame 22. When the angles between the second bed board 14 and the first bed board 6, and between the third bed board 15 and the first bed board 6 change to adjust the patient to a sitting position, the patient can place their arms on the armrest frame 22. The fixed rods 20 are located between the adjusting rod 19 and the armrest frame 22. The top ends of the two fixed rods 20 are respectively fixedly connected to the second bed board 14 and the third bed board 15. When the adjusting rod 19 moves with the second toothed plate 13, the fixed rods 20 will rotate around their hinge joints with the adjusting rod 19, thereby adjusting the angles between the second bed board 14 and the first bed board 6, and between the third bed board 15 and the first bed board 6. On one side of the bottom end of the sleeve rod 17, a connecting block 26 is fixedly connected. On the top surface of the second toothed plate 13, a push-button switch 27 is fixedly connected. The push-button switch 27 is arranged corresponding to the connecting block 26. The push-button switch 27 is electrically connected to the air pump 25. When the cylindrical rod 16 moves with the second toothed plate 13, the sleeve rod 17 rises or falls along the cylindrical rod 16. At this time, the connecting plate 4 is separated from or connected to the push-button switch 27, thereby controlling the opening and closing of the air pump 25.
[0037] Airbags 24 are fixedly installed at the outer edge positions of the first bed board 6, the second bed board 14, and the third bed board 15. An air pump 25 is fixedly installed on the side of the second bed board 14 away from the first bed board 6. The air outlet pipe of the air pump 25 penetrates through the airbag 24 and is fixedly connected to the inner wall of the airbag 24. When the air pump 25 is started, the air pump 25 can blow air into the airbag 24, thereby protecting the patient with the airbag 24 and preventing the patient from falling. A handle 21 is fixedly installed at the bottom of the second bed board 14, facilitating the pushing and pulling by medical staff. A foot pad 23 is fixedly installed on the side of the third bed board 15 away from the first bed board 6. When the patient is in a sitting position, the foot pad 23 can provide support for the patient's feet and improve the comfort of the patient.
[0038] When the combined power-assisted convalescent bed provided by the present invention is in use, the worm 11 is driven by a motor to perform a fixed-axis reciprocating rotation. Through the gear 8 provided on the connecting plate 4 and the worm gear 12 provided on the gear 8, along with the meshing transmission between the worm gear 12 and the worm 11, the worm gear 12 drives the gear 8 to perform a fixed-axis reciprocating rotation synchronously under the action of the worm 11. A first toothed plate 7 is provided on the second chute 102, and the first toothed plate 7 can be in meshing transmission with the gear 8, so that the gear 8 reciprocates on the first toothed plate 7. A support rod 5 is provided on the connecting plate 4, and the support rod 5 supports the first bed plate 6. Along with the gear 8 reciprocating on the first toothed plate 7, the moving wheel 2 drives the first bed plate 6 to perform a horizontal reciprocating movement on the inner wall of the first chute 101.
[0039] Through the second toothed plate 13 provided on the third chute 91 and the through groove 92 opened on the third chute 91, the second toothed plate 13 is in meshing transmission with the gear 8, so that the second toothed plate 13 performs a horizontal reciprocating movement along the inner wall of the third chute 91 under the action of the gear 8.
[0040] The patient lies flat on the first bed plate 6, the second bed plate 14, and the third bed plate 15. When the first bed plate 6 moves towards the end close to the inclined surface of the base 1, the second toothed plate 13 moves horizontally in the same direction. Through the connecting rod 18 provided on the sleeve rod 17, and the connecting rod 18 is rotatably connected to the fixed rod 20 through a pin shaft, the connecting rod 18 is driven by the second toothed plate 13 to push the fixed rods 20 at both ends to rotate in the C direction. At the same time, the second bed plate 14 rotates away from the base 1 under the action of the fixed rod 20, and the third bed plate 15 rotates towards the base 1, which can adjust the patient to a sitting state, thus avoiding blood stasis caused by the patient lying flat for a long time and promoting blood return. Through the foot pad 23 provided on the third bed plate 15, the patient's feet can be placed on the foot pad 23, improving the comfort of the patient. Along with the fixed rod 20 rotating in the C direction, the sleeve rod 17 axially moves in the vertical direction away from the second toothed plate 13 on the first bed plate 6.
[0041] When the first bed plate 6 moves towards the end away from the inclined surface of the base 1, it is opposite to the above mechanism, so that the connecting rod 18 rotates in the D direction. At the same time, the second bed plate 14 rotates towards the base 1 under the action of the fixed rod 20, and the third bed plate 15 rotates away from the base 1, which can adjust the patient to a lying flat state. Along with the fixed rod 20 rotating in the D direction, the sleeve rod 17 axially moves in the vertical direction towards the second toothed plate 13.
[0042] When the patient is in a sitting position, the gear 8 moves to the limit distance at the inclined plane end of the first tooth plate 7 close to the base 1, and the gear 8 is disengaged from the first tooth plate 7. Through the handle 21 provided on the second bedplate 14 and the inclined plane provided on the fixed block 10, the medical staff can pull the handle 21 to move the convalescent bed out of the base 1. At the same time, the patient can be pushed outdoors to contact the natural scenery through the handle 21, which can further improve the body's resistance to external stimuli, increase the joy of life and relieve the psychological pressure of the patient. Through the armrest frame 22 provided on the adjusting rod 19, when the sleeve rod 17 moves away from the second tooth plate 13, the armrest frame 22 moves away from the base 1 under the action of the adjusting rod 19, enabling the patient to rest their arm on the armrest frame 22 in a sitting position, further improving the comfort of the patient.
[0043] Through the connecting block 26 provided on the sleeve rod 17 and the pressure switch 27 provided on the second tooth plate 13, when the sleeve rod 17 moves towards the second tooth plate 13 to the limit distance, the patient remains in a lying position. Thus, the connecting block 26 contacts and presses the pressure switch 27, and the pressure switch 27 is electrically connected to the air pump 25. Furthermore, the pressure switch 27 powers on the air pump 25, enabling the air pump 25 to inflate the airbag 24 to protect the patient from falling off the convalescent bed. When the sleeve rod 17 moves away from the second tooth plate 13, the connecting block 26 is disengaged from the pressure switch 27, enabling the air pump 25 to discharge the gas inside the airbag 24.
[0044] Therefore, the present invention adopts the above-mentioned combined assisted convalescent bed. The adjustment device can adjust the angles of the second bedplate and the third bedplate to adjust the patient to a sitting position, thus avoiding blood stasis caused by the patient lying flat for a long time and promoting blood return; a moving device is provided on the base, and an inclined plane is provided on one side of the base, which is convenient for medical staff to push the patient outdoors to contact the natural scenery through the handle, further improving the body's resistance to external stimuli, increasing the joy of life and relieving the psychological pressure of the patient; airbags are provided at the outer edge positions of the first bedplate, the second bedplate, and the third bedplate, and the air pump is electrically connected to the pressure switch at the top of the second tooth plate. The pressure switch powers on the air pump, enabling the air pump to inflate the airbags to protect the patient from falling off the convalescent bed.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
