Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a universal multifunctional auxiliary bed. Background Technology

[0002] Internal medicine includes respiratory medicine, gastroenterology, cardiology, neurology, oncology, endocrinology, hematology, infectious diseases, and pediatrics. Respiratory medicine consultations cover diseases such as the common cold, pneumonia, emphysema, tuberculosis, bronchiectasis, asthma, lung cancer, pulmonary heart disease, respiratory failure, chronic bronchitis, pneumothorax, lung abscess, pleural effusion, and interstitial lung disease. Patients requiring this care often need hospitalization, where auxiliary beds play a crucial role.

[0003] Compared to younger people, older people are more susceptible to internal medical conditions such as pneumonia, emphysema, tuberculosis, and asthma. Since older people are already less mobile, these kinds of internal medical conditions will make their mobility even more difficult.

[0004] Currently available medical assistive beds are primarily designed for sleeping, and their limited functionality no longer meets the needs of the elderly and patients. For example, the height of the side rails on existing medical assistive beds cannot be adjusted, which requires the elderly to exert considerable effort to get in and out of bed, making it inconvenient to get up at night to use the toilet. Furthermore, the non-lowerable side rails make it difficult for medical staff and caregivers to assist them in getting in, out of, and sitting up. Summary of the Invention

[0005] The purpose of this invention is to provide a universal multifunctional auxiliary bed that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a general-purpose multifunctional auxiliary bed, comprising a bed frame, wherein a headboard is hinged to the surface of the bed frame via a hinge rod one, and a footboard is hinged to the surface of the bed frame via a hinge rod two;

[0007] It also includes two connecting plates. The sides of the bed are fixedly connected to a fixed frame through the two connecting plates. Two telescopic rods are symmetrically arranged on the upper surface of the fixed frame. The ends of the two telescopic rods are fixedly connected to a movable frame.

[0008] The fixed frame is equipped with a drive component for driving the moving frame to descend.

[0009] The bed frame is provided with auxiliary components underneath to allow the head and foot of the bed to tilt.

[0010] Optionally, the driving component includes a threaded rod rotatably connected to the inner wall of the fixed frame on a fixed axis. The surface of the threaded rod has multiple oppositely arranged threaded grooves. The surface of the threaded rod is threadedly connected to multiple sets of symmetrically arranged movable blocks I. The upper surfaces of each pair of movable blocks I are respectively hinged to two telescopic frames. The two telescopic frames are hinged to each other. The upper ends of the two telescopic frames are respectively hinged to two symmetrically arranged movable blocks II. The surface of the movable frame has a sliding groove for the movable blocks II to slide and adapt to each other. The movable blocks II are slidably connected to the movable frame through the sliding groove.

[0011] Optionally, the driving component further includes a rotating rod, and a bevel gear transmission mechanism is provided between the rotating rod and the threaded rod. A fixing plate is fixedly connected to the side of the fixing frame. The rotating rod passes through the fixing plate and is rotatably connected to it on a fixed axis. A rotating plate is fixedly connected to the surface of the rotating rod, and a rotating column is fixedly connected to the surface of the rotating plate. The surface of the rotating column is provided with anti-slip texture.

[0012] Optionally, both the fixed frame and the movable frame are provided in two sets, and the two sets of fixed frames and the two sets of movable frames are symmetrically distributed about the axis of the bed. A belt pulley transmission mechanism is provided between the two threaded rods.

[0013] Optionally, the auxiliary component includes four connecting rods arranged in two groups. The ends of the two groups of connecting rods are respectively fixedly connected to the inner walls of the two movable frames. The ends of the two groups of connecting rods are respectively fixedly connected to two connecting blocks, and a fixing rod is fixedly connected between the two connecting blocks.

[0014] Optionally, the auxiliary component further includes a rack row, the fixing rod passes through the rack row and is fixedly connected to it, a support plate is fixedly connected to the side of the connected plate, a rotating shaft is rotatably connected to the surface of the support plate, and a gear that meshes with the rack row is fixedly connected to the surface of the rotating shaft.

[0015] The lower surface of the bed is fixedly connected to a limiting rod, and also includes a second rack. The limiting rod passes through the second rack and is slidably connected to it. The second rack meshes with the gear.

[0016] Optionally, it also includes hinge rod one and hinge rod two, wherein the lower surface of the foot of the bed is hinged to the rack row one via hinge rod one, and the lower surface of the head of the bed is hinged to the rack row two via hinge rod two.

[0017] Optionally, it also includes an auxiliary plate, wherein the surface of the foot of the bed has a slot one for inserting and fitting the auxiliary plate, and two symmetrically arranged protrusions are fixedly connected to the side of the auxiliary plate, and the surface of the foot of the bed has a slot two for sliding and fitting the protrusions.

[0018] A support rod is fixedly connected between the two fixed frames, and a baffle is fixedly connected to the surface of the support rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] I. This invention, through the combined use of a movable frame and a telescopic frame, can replace guardrails to protect patients with internal medicine diseases who are resting on the bed.

[0021] When a patient with an internal medicine condition needs to get out of bed, rotating the rotating column causes the two threaded rods to rotate. Under the action of the telescopic frame, the moving frame moves downward and the telescopic rods retract until the moving frame is level with the bed surface. At this point, rotating the rotating column stops, and the moving frame and telescopic frame no longer obstruct the sides of the bed. The patient can then easily get out of bed, solving the problem that existing auxiliary beds for internal medicine patients require considerable effort for the elderly to get in and out of bed and are inconvenient for getting up at night to use the toilet because the height of the side rails cannot be adjusted.

[0022] Second, this invention uses the descent of the movable frame to cause the foot of the bed to tilt downwards, while the head of the bed begins to tilt upwards. Once the movable frame has descended to the same height as the bed, the foot of the bed will tilt downwards and the head of the bed will tilt upwards. At this point, with the head and foot of the bed tilted, patients with internal medicine diseases lying on the bed can better use their strength to sit up from the bed, making it easier for them to get out of bed. It also makes it easier for medical staff and caregivers at the bedside to better assist patients, providing convenience for patients to get out of bed and get up.

[0023] Third, this invention causes the auxiliary board to protrude to the upper surface of the foot of the bed by tilting the foot of the bed downwards. At this time, patients with internal medicine diseases can place their feet on the auxiliary board. With the help of the auxiliary board, patients with internal medicine diseases can better use their strength when getting out of bed, making it more practical. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8 The present invention provides a technical solution: a general-purpose multi-functional auxiliary bed, including a bed body 3, a headboard 1 hinged to the surface of the bed body 3 by a hinge rod 2, and a footboard 4 hinged to the surface of the bed body 3 by a hinge rod 2.

[0035] It also includes two connecting plates 24. The side of the bed body 3 is fixedly connected to a fixed frame 7 through the two connecting plates 24. Two telescopic rods 6 are symmetrically arranged on the upper surface of the fixed frame 7. The ends of the two telescopic rods 6 are fixedly connected to a movable frame 8.

[0036] The fixed frame 7 is equipped with a drive component for driving the moving frame 8 to descend.

[0037] The bed frame 3 is equipped with auxiliary components for tilting the headboard 1 and footboard 4.

[0038] More specifically, in this embodiment, when in use, the patient with internal medicine disease lies on the bed 3, with the patient's head naturally resting on the bed 3 and the lower legs and feet naturally placed on the upper surface of the foot of the bed 4. The fixed frame 7 and the movable frame 8 on both sides of the bed 3 can replace the guardrail when the patient with internal medicine disease is resting on the bed 3, so as to protect the patient with internal medicine disease and prevent the patient from falling off the bed when turning over, causing unnecessary personal injury.

[0039] When a patient with internal medical conditions needs to get out of bed, the moving frame 8 can be lowered to a position level with the height of the bed 3 by controlling the drive component. At this time, the moving frames 8 on both sides of the bed 3 will no longer obstruct the patient with internal medical conditions.

[0040] At the same time, as the moving frame 8 descends, the headboard 1 tilts upward and the footboard 4 tilts downward under the action of the auxiliary components. With the tilting of the headboard 1 and the footboard 4, patients with internal medicine diseases lying on the bed 3 can better use their strength to sit up from the bed 3. With the descent of the moving frame 8, the patient can easily get out of bed, and the medical staff and caregivers at the bedside can also better support the patients with internal medicine diseases, making it easier for them to get out of bed and get up.

[0041] Similarly, after the patient gets back into bed, controlling the drive unit again will reset the moving frame 8, allowing it to once again shield the sides of the bed 3 to protect the patient with internal medicine conditions.

[0042] Example 2, based on the above examples,

[0043] Furthermore, the driving component in Embodiment 1 is disclosed. The driving component includes a threaded rod 9 that is rotatably connected to the inner wall of the fixed frame 7. The surface of the threaded rod 9 has multiple oppositely arranged threaded grooves. The surface of the threaded rod 9 is threadedly connected to multiple sets of symmetrically arranged movable blocks 14. The upper surfaces of each pair of movable blocks 14 are respectively hinged to two telescopic frames 15. The two telescopic frames 15 are hinged to each other. The upper ends of the two telescopic frames 15 are respectively hinged to two symmetrically arranged movable blocks 16. The surface of the movable frame 8 is provided with a sliding groove for the movable blocks 16 to slide and adapt to each other. The movable blocks 16 are slidably connected to the movable frame 8 through the sliding groove.

[0044] The driving component also includes a rotating rod 11, and a bevel gear transmission mechanism 13 is provided between the rotating rod 11 and the threaded rod 9. A fixing plate is fixedly connected to the side of the fixing frame 7. The rotating rod 11 passes through the fixing plate and is rotatably connected to it on a fixed axis. A rotating plate 12 is fixedly connected to the surface of the rotating rod 11. A rotating column is fixedly connected to the surface of the rotating plate 12. The surface of the rotating column is provided with anti-slip texture.

[0045] Two sets of fixed frames 7 and two sets of movable frames 8 are provided. The two sets of fixed frames 7 and the two sets of movable frames 8 are symmetrically distributed about the axis of the bed body 3. A belt pulley transmission mechanism 10 is provided between the two threaded rods 9.

[0046] More specifically, in this embodiment, when a patient with an internal medicine disease needs to get out of bed, the rotating column is rotated, which causes the rotating plate 12 to start rotating. The rotation of the rotating plate 12 will then cause the rotating rod 11 to start rotating. The anti-slip texture on the surface of the rotating column can prevent the user's hand from slipping on the rotating column when rotating it.

[0047] Under the action of the bevel gear transmission mechanism 13, the rotation of the rotating rod 11 will drive the threaded rod 9 in one fixed frame 7 to start rotating. Under the action of the belt pulley transmission mechanism 10, the rotation of one threaded rod 9 will drive the threaded rods 9 in two fixed frames 7 to rotate synchronously.

[0048] Because the threaded rod 9 has multiple oppositely arranged threaded grooves on its surface, the rotation of the threaded rod 9 will cause the two moving blocks 14 to move away from each other. Under the action of the two telescopic frames 15, the movement of the moving blocks 14 will cause the two moving blocks 16 to slide in the grooves on the surface of the moving frame 8, which will drive the moving frame 8 to move downward and cause the telescopic rod 6 to retract until the moving frame 8 drops to the same height as the surface of the bed 3, at which point the rotation of the rotating column will stop. At this time, the moving frame 8 and the telescopic frame 15 will no longer obstruct the side of the bed 3, and patients with internal diseases can easily get out of bed.

[0049] Similarly, after the patient gets back into bed, rotating the rotating column in the opposite direction will reset the moving frame 8, thus restoring protection to the bed body 3.

[0050] Example 3, based on the above examples,

[0051] Furthermore, the auxiliary components in Embodiment 1 are disclosed. The auxiliary components include four connecting rods 25 arranged in two groups. The ends of the two groups of connecting rods 25 are respectively fixedly connected to the inner walls of the two movable frames 8. The ends of the two groups of connecting rods 25 are respectively fixedly connected to two connecting blocks 28. A fixing rod is fixedly connected between the two connecting blocks 28.

[0052] It also includes a rack row 19, a fixing rod passing through the rack row 19 and fixedly connected to it, a support plate fixedly connected to the side of the connected plate 24, a rotating shaft rotatably connected to the surface of the support plate, and a gear 20 meshing with the rack row 19 fixedly connected to the surface of the rotating shaft.

[0053] The lower surface of the bed 3 is fixedly connected to a limiting rod 21, and also includes a rack 22. The limiting rod 21 passes through the rack 22 and is slidably connected to it. The rack 22 meshes with the gear 20.

[0054] It also includes hinge rod 18 and hinge rod 23. The lower surface of the foot of the bed 4 is hinged to rack 19 via hinge rod 18, and the lower surface of the head of the bed 1 is hinged to rack 22 via hinge rod 23.

[0055] More specifically, in this embodiment, when the rotating column is rotated, the moving frame 8 is lowered. The downward movement of the moving frame 8 will cause the connecting rod 25 to move downward. The downward movement of the connecting rod 25 will cause the two connecting blocks 28 to move downward synchronously, thereby causing the rack row 19 between the two connecting rods 25 to start moving downward.

[0056] Under the action of hinge rod 18, the downward movement of rack 19 will cause the tailstock 4 to begin to deflect downward with hinge rod 2 as the center.

[0057] The downward movement of rack 19 will also cause the gear 20 meshing with it to start rotating. The rotation of gear 20 will cause rack 22 meshing with it to start moving upward. Under the action of hinge rod 23, the upward movement of rack 22 will cause headstock 1 to start deflecting upward with the axis of hinge rod 2 as the center.

[0058] As the moving frame 8 moves downward, the foot of the bed 4 will tilt downward, and the head of the bed 1 will tilt upward. After the moving frame 8 descends to the same height as the bed 3, the foot of the bed 4 will tilt downward by 45 degrees and the head of the bed 1 will tilt upward by 45 degrees. At this time, with the tilt of the head of the bed 1 and the foot of the bed 4, patients with internal medicine diseases lying on the bed 3 can better use their strength to sit up from the bed 3, making it easier for them to get out of bed. It also makes it easier for medical staff and caregivers at the bedside to better support the patients, making it more convenient for them to get out of bed and get up.

[0059] Similarly, after the patient with internal medicine disease gets back into bed, the rotating column is reversed, and as the moving frame 8 moves upward, it will cause the head of the bed 1 and the foot of the bed 4 to reset.

[0060] Example 4, based on the above examples,

[0061] Furthermore, in order to enable patients with internal diseases to better leverage their strength when getting up, an auxiliary plate 5 is also included. The surface of the foot of the bed 4 has a slot 1 for the auxiliary plate 5 to be inserted and adapted. Two symmetrically arranged protrusions 26 are fixedly connected to the side of the auxiliary plate 5. The surface of the foot of the bed 4 has a slot 27 for the protrusions 26 to slide and adapt.

[0062] A support rod is fixedly connected between the two fixed frames 7, and a baffle 17 is fixedly connected to the surface of the support rod.

[0063] More specifically, in this embodiment, when the foot of the bed 4 begins to deflect downwards, it will also drive the auxiliary plate 5 to deflect synchronously. When the auxiliary plate 5 moves to a position that is in contact with the baffle 17, it will stop deflecting. At this time, the foot of the bed 4 will continue to deflect, that is, the foot of the bed 4 will start to move relative to the auxiliary plate 5. At the same time, the protrusion 26 will slide in the slot 27. After the foot of the bed 4 deflects downwards by 45 degrees, the auxiliary plate 5 will protrude to the upper surface of the foot of the bed 4. At this time, the size of the auxiliary plate 5 protruding is just enough for the patient with internal medicine disease to place two feet. Thus, under the action of the auxiliary plate 5, the patient with internal medicine disease can better use the support when getting up, making it more practical.

[0064] Working principle: This is a general-purpose multi-functional auxiliary bed. When in use, patients with internal medicine diseases lie on the bed body 3, with their heads naturally resting on the bed body 3 and their lower legs and feet naturally placed on the upper surface of the foot of the bed 4. The fixed frames 7 and movable frames 8 on both sides of the bed body 3 can replace guardrails, protecting patients with internal medicine diseases when they are resting on the bed body 3, and preventing them from falling off the bed and causing unnecessary personal injury when they turn over.

[0065] When a patient with an internal medicine condition needs to get out of bed, the rotating column is rotated, which causes the rotating plate 12 to start rotating, thereby causing the rotating rod 11 to start rotating. Under the action of the bevel gear transmission mechanism 13 and the belt pulley transmission mechanism 10, the rotation of the rotating rod 11 will cause the threaded rods 9 in the two fixed frames 7 to start rotating synchronously.

[0066] Because the threaded rod 9 has multiple oppositely arranged threaded grooves on its surface, the rotation of the threaded rod 9 will cause the two moving blocks 14 to move away from each other. Under the action of the two telescopic frames 15, the two moving blocks 16 slide in the grooves on the surface of the moving frame 8, which will drive the moving frame 8 to move downward and cause the telescopic rod 6 to retract until the moving frame 8 drops to the same height as the surface of the bed 3. At this time, the rotation of the rotating column will stop. The moving frame 8 and the telescopic frame 15 will no longer obstruct the side of the bed 3, and the patient with internal medicine disease can easily get out of bed.

[0067] During the descent of the moving frame 8, the downward movement of the moving frame 8 will cause the connecting rod 25 to move downward, thereby causing the two connecting blocks 28 to move downward synchronously. This will cause the rack row 19 between the two connecting rods 25 to start moving downward. Under the action of the hinge rod 18, the downward movement of the rack row 19 will cause the tailstock 4 to start deflecting downward with the hinge rod 2 as the center.

[0068] The downward movement of rack 19 will also cause the gear 20 meshing with it to start rotating. The rotation of gear 20 will cause rack 22 meshing with it to start moving upward. Under the action of hinge rod 23, the upward movement of rack 22 will cause headstock 1 to start deflecting upward with the axis of hinge rod 2 as the center.

[0069] As the moving frame 8 moves downward, the foot of the bed 4 will tilt downward, and the head of the bed 1 will tilt upward. After the moving frame 8 descends to the same height as the bed 3, the foot of the bed 4 will tilt downward by 45 degrees and the head of the bed 1 will tilt upward by 45 degrees. At this time, with the tilt of the head of the bed 1 and the foot of the bed 4, patients with internal medicine diseases lying on the bed 3 can better use their strength to sit up from the bed 3, making it easier for them to get out of bed. It also makes it easier for medical staff and caregivers at the bedside to better support the patients, making it more convenient for them to get out of bed and get up.

[0070] Furthermore, as the foot of the bed 4 begins to deflect downwards, the auxiliary plate 5 will also deflect synchronously. When the auxiliary plate 5 moves to a position where it is in contact with the baffle 17, it will stop deflecting. At this time, the foot of the bed 4 will continue to deflect, meaning that the auxiliary plate 5 will begin to move relative to the foot of the bed 4. Simultaneously, the protrusion 26 will slide within the slot 27. After the foot of the bed 4 deflects downwards by 45 degrees, the auxiliary plate 5 will protrude onto the upper surface of the foot of the bed 4. At this time, the size of the auxiliary plate 5 protruding is just enough for a patient with internal medicine disease to place their two feet. With the help of the auxiliary plate 5, patients with internal medicine disease can better leverage their strength when getting up, making it more practical.
