Abstract
Description
Technical Field
[0001] This invention relates to the field of medical bed technology, specifically a medical bed with a caregiver module. Background Technology
[0002] In current medical and nursing practices, the care of hospitalized patients relies heavily on caregivers. However, the functional design of existing medical beds is almost entirely patient-centered, severely neglecting the actual rest needs of caregivers.
[0003] Currently, most wards have limited space, making it difficult to provide dedicated companion beds. Even when available, these are often individual folding beds or simple reclining chairs, which not only occupy valuable ward passageway space, hindering the movement of medical staff and emergency procedures, but are also difficult to store when not in use, causing management inconvenience. Furthermore, for postoperative patients, those with limited mobility, or those in agitated states, there is a high risk of falls when they turn over or move around in bed. Although some beds are equipped with traditional fixed guardrails, these primarily function on the sides of the bed, offering limited protection, and require repeated disassembly and removal when patients get in and out of bed, making the process cumbersome.
[0004] To address the aforementioned issues, we have made improvements by proposing a medical bed with a companion module. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention provides a medical bed with a caregiver module, comprising a first transverse support plate, both ends of which are equipped with braked universal wheels, a portal support plate fixedly connected to the top surface of the first transverse support plate, a bed board fixedly connected to the top surface of the two portal support plates, a horizontal sliding groove provided on the upper side of the portal support plate, and the same sliding plate slidably connected to the horizontal sliding groove of the two portal support plates, side guard plates fixedly connected to both sides of the sliding plate, two mounting plates symmetrically fixedly connected between the two portal support plates, a reciprocating threaded rod rotatably connected between the two mounting plates, a vertical plate threadedly connected to the outer wall of the reciprocating threaded rod, and the top of the vertical plate fixedly connected to the middle of the bottom surface of the sliding plate; Two second transverse support plates are symmetrically and fixedly connected between the two first transverse support plates. The top surface of the second transverse support plates is provided with a slide rail. The top surface of the two second transverse support plates is slidably connected to a companion bed board through the slide rail. The bottom surface of the two second transverse support plates is rotatably connected to a transmission rod through a bearing seat. A rope reel is coaxially and fixedly connected to the outer wall of the transmission rod. A rotating rod is rotatably connected to the middle of each of the two first transverse support plates. A guide rope reel and a release rope reel are rotatably connected to the outer wall of the two rotating rods, respectively. A connecting block is fixedly connected to the right side of the bottom surface of the companion bed board. A transmission mechanism is installed between the end of the transmission rod extending to the outside of the bearing seat and the end of the reciprocating threaded rod extending to the outside of the mounting plate.
[0006] As a preferred embodiment of the present invention, a horizontal slide rod is fixedly connected between the opposite sides of the horizontal slide groove, and the horizontal slide rod is slidably connected to the slide plate.
[0007] As a preferred embodiment of the present invention, a geared motor is mounted on the outer side of one of the mounting plates, and the output shaft of the geared motor is coaxially and fixedly connected to a reciprocating threaded rod.
[0008] As a preferred embodiment of the present invention, a first pull rope is fixedly connected to the right side of the connecting block, and the first pull rope is fixedly connected to the winding reel after being guided by the guide rope reel. A second pull rope is fixedly connected to the left side of the connecting block, and the second pull rope is fixedly connected to the unwinding reel.
[0009] As a preferred embodiment of the present invention, a bearing plate is fixedly connected between the middle of the two portal support plates, and two storage chambers are symmetrically installed on the top surface of the bearing plate. A sliding groove for the vertical plate to pass through is also provided in the middle of the top surface of the bearing plate.
[0010] As a preferred embodiment of the present invention, the transmission mechanism includes a driving belt pulley and a driven belt pulley. One end of the reciprocating threaded rod extending outside the mounting plate is coaxially and fixedly connected to the driving belt pulley. One end of the transmission rod extending outside the bearing seat is coaxially and fixedly connected to the driven belt pulley. The driving belt pulley and the driven belt pulley are driven by a transmission belt.
[0011] As a preferred embodiment of the present invention, an anti-reverse mechanism is installed on the driven pulley. The anti-reverse mechanism includes a circular groove coaxially formed on the side of the driven pulley. A right-angled triangular block is fixedly connected to the side of the circular groove. A spring rod is fixedly connected to the outer wall of the transmission rod extending into the circular groove.

[0013] The beneficial effects of this invention are as follows: When a caregiver needs to rest, this medical bed with a companion module only requires starting the geared motor. The geared motor drives the reciprocating threaded rod to rotate counterclockwise, which in turn drives the active belt pulley to rotate counterclockwise. The active belt pulley drives the driven belt pulley to rotate counterclockwise via the transmission belt, and then drives the transmission rod to rotate via the anti-reverse mechanism. The transmission rod drives the rope winding reel to wind up the first pull rope, which pulls out the companion bed board. The second pull rope is then pulled out from the rope unwinding reel. The caregiver only needs to rotate the adjusting bolt to allow the caregiver to rest nearby, making it convenient to respond to the patient's needs at any time. When folded up, it can be perfectly stored under the bed board without occupying extra floor space, greatly optimizing the ward environment. Attached Figure Description

[0016] Example: Figures 1-7 As shown, a medical bed with a companion module includes a first transverse support plate 1. Both ends of the first transverse support plate 1 are equipped with brake casters. A portal support plate 2 is fixedly connected to the top surface of the first transverse support plate 1. A bed board 3 is fixedly connected to the top surface of the two portal support plates 2. A horizontal sliding groove is opened on the upper side of the portal support plate 2. The same sliding plate 4 is slidably connected to the horizontal sliding groove of the two portal support plates 2. Side guard plates 5 are fixedly connected to both sides of the sliding plate 4. Two mounting plates 7 are symmetrically fixedly connected between the two portal support plates 2. A reciprocating threaded rod 8 is rotatably connected between the two mounting plates 7. A vertical plate 9 is threadedly connected to the outer wall of the reciprocating threaded rod 8. The top of the vertical plate 9 is fixedly connected to the middle of the bottom surface of the sliding plate 4. Two second transverse support plates 11 are symmetrically and fixedly connected between the two first transverse support plates 1. The top surface of the second transverse support plate 11 is provided with a slide rail. The top surface of the two second transverse support plates 11 is slidably connected to the companion bed board 14 through the slide rail. The bottom center of the two second transverse support plates 11 is rotatably connected to the transmission rod 12 through the bearing seat. The outer wall of the transmission rod 12 is coaxially fixedly connected to the rope reel 13. The middle of the two first transverse support plates 1 is rotatably connected to the rotating rod. The outer wall of the two rotating rods is rotatably connected to the guide rope reel 15 and the release rope reel 16, respectively. The bottom right side of the companion bed board 14 is fixedly connected to the connecting block 17. It should be noted that a spring is installed at the rotating rod of the release rope reel 16.
[0017] A transmission mechanism is installed between the end of the transmission rod 12 extending to the outside of the bearing housing and the end of the reciprocating threaded rod 8 extending to the outside of the mounting plate 7.
[0018] A horizontal slide bar 6 is fixedly connected between the opposite sides of the horizontal slide groove, and the horizontal slide bar 6 is slidably connected to the slide plate 4.
[0019] A geared motor 10 is mounted on the outer side of one of the mounting plates 7, and the output shaft of the geared motor 10 is coaxially and fixedly connected to the reciprocating threaded rod 8.
[0020] A first pull rope 18 is fixedly connected to the right side of the connecting block 17. After being guided by the guide rope reel 15, the first pull rope 18 is fixedly connected to the winding rope reel 13. A second pull rope 19 is fixedly connected to the left side of the connecting block 17. The second pull rope 19 is fixedly connected to the unwinding rope reel 16.
[0021] A bearing plate 20 is fixedly connected between the middle of the two portal support plates 2. Two storage chambers 21 are symmetrically installed on the top surface of the bearing plate 20. A sliding groove for the vertical plate 9 to pass through is also provided in the middle of the top surface of the bearing plate 20. Figure 4As shown, storage room 21 can store care supplies.
[0022] The transmission mechanism includes a driving belt pulley 22 and a driven belt pulley 23. One end of the reciprocating threaded rod 8 extending to the outside of the mounting plate 7 is coaxially and fixedly connected to the driving belt pulley 22. One end of the transmission rod 12 extending to the outside of the bearing housing is coaxially and fixedly connected to the driven belt pulley 23. The driving belt pulley 22 and the driven belt pulley 23 are driven by a transmission belt.
[0023] An anti-reverse mechanism is installed on the driven pulley 23. The anti-reverse mechanism includes a circular groove 24 coaxially formed on the side of the driven pulley 23. A right-angled triangular block 25 is fixedly connected to the side of the circular groove 24. A spring rod 26 is fixedly connected to the outer wall inside the circular groove 24 where the transmission rod 12 extends. One end of the movable end of the spring rod 26 is provided with a chamfer that cooperates with the right-angled triangular block 25.
[0024] like Figure 6 and Figure 7 As shown, when the driven belt pulley 23 rotates clockwise, the hypotenuse of the right-angled triangle block 25 will abut against the spring rod 26, causing the spring rod 26 to be compressed. That is, the clockwise rotation of the driven belt pulley 23 will not drive the transmission rod 12 to rotate. When the driven belt pulley 23 rotates counterclockwise, the straight side of the right-angled triangle block 25 will abut against the spring rod 26, and the spring rod 26 will not be compressed. That is, the counterclockwise rotation of the driven belt pulley 23 will drive the transmission rod 12 to rotate.
[0025] A folding plate 27 is bolted to the left side of the bottom surface of the accompanying bed board 14. An adjusting bolt 28 is threaded to the bottom of the folding plate 27, and a support foot is coaxially fixed to the bottom end of the adjusting bolt 28. Figure 1 As shown, when the bed board 14 is removed, the height of the support feet can be adjusted by rotating the adjusting bolt 28 to make it flush with the ground.
[0026] Working principle: This type of medical bed with a patient companion module requires checking its functionality before use. When the patient is on the bed, the side guard plate 5 should be positioned as follows: Figure 1 As shown, when a patient needs to be transferred, the geared motor 10 is started. The geared motor 10 drives the reciprocating threaded rod 8 to rotate clockwise. The reciprocating threaded rod 8 drives the vertical plate 9 to move, and the sliding plate 4 moves synchronously with the vertical plate 9. Finally, it moves the side guard plate 5 from the middle position of the bed board 3 to both sides, making it convenient for medical staff to transfer the patient.
[0027] When the caregiver needs to rest, simply start the geared motor 10. The geared motor 10 drives the reciprocating threaded rod 8 to rotate counterclockwise, which in turn drives the active belt pulley 22 to rotate counterclockwise. The active belt pulley 22 drives the driven belt pulley 23 to rotate counterclockwise via the transmission belt, and then drives the transmission rod 12 to rotate via the anti-reverse mechanism. The transmission rod 12 drives the rope winding disc 13 to rotate and wind up the first pull rope 18. The first pull rope 18 pulls out the caregiver bed board 14, and the second pull rope 19 is pulled out from the rope release disc 16. The caregiver only needs to rotate the adjusting bolt 28 to rest on the caregiver bed board.
[0028] When it is necessary to retract the companion bed board 14, simply rotate the reciprocating threaded rod 8 clockwise. Under the action of the spring, the rope release disc 16 retracts the companion bed board 14 through the second pull rope 19.
[0029] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
