Description

Technical Field

[0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a folding structure of a household nursing bed. Background Art

[0002] A home nursing bed is an auxiliary device designed for home environments, mainly serving the elderly, the disabled or patients who need long-term bed rest for recovery. It provides comfortable and convenient nursing services, aiming to meet the special needs of these people in daily life and rehabilitation. Home nursing beds usually have multiple functions, such as back lifting, leg lifting, toilet opening lifting, turning over, etc. These functions are achieved through electronic control components, which greatly improves the patient's quality of life and reduces the burden on family members during the nursing process. With the intensification of population aging and the increase in home care needs, the market demand for home nursing beds is growing. For patients who need long-term care, this type of bed not only provides the necessary support and comfort, but also facilitates the transfer of patients when conducting outdoor activities or receiving medical care, thereby improving the patient's quality of life and convenience.

[0003] Although traditional home nursing beds have met the basic needs of home nursing to a certain extent, they are insufficient in functionality. For the elderly, disabled people and other people who need long-term or short-term bed rest for recovery, a single turning method is far from meeting their needs. In particular, it may increase the risk of complications for patients who are at risk of pressure sores or require drainage in a specific position. Moreover, traditional nursing beds lack delicate control and cannot perform personalized angle adjustments according to the patient's specific rehabilitation needs. For patients who need to stay in bed for a long time and have limited lower limb function, it not only affects their comfort, but also limits the effectiveness of rehabilitation exercises and delays the recovery process. For this reason, the present invention proposes a folding structure for a home nursing bed. Summary of the invention

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a folding structure for a household nursing bed, which has the following beneficial effects: The folding structure of the home nursing bed can adjust the height of the bed according to the actual needs of the patient, making it convenient for the patient to get in and out of bed and reducing the trouble caused by height discomfort. The toilet hole lifting device automatically opens and closes the toilet hole, making it convenient for the patient to use the toilet and avoiding the tedious and inconvenient manual operation. The turning device reduces the workload of nursing staff through automatic turning assistance, and effectively prevents the occurrence of complications such as bedsores. The leg lifting and back lifting devices adjust the height of the patient's legs and back respectively, providing nursing staff with more operating space, facilitating leg and back care or treatment, thereby improving the overall care effect. The integration of these functions makes the nursing bed more humane and meets the personalized needs of different patients.

[0016] The folding structure of the home nursing bed significantly improves the nursing efficiency and quality. Traditional nursing beds often require nursing staff to manually adjust various functions, which is not only time-consuming and laborious, but also difficult to ensure the accuracy and consistency of the adjustment. The nursing bed of the present invention realizes the automatic adjustment of various functions through mechanical structures such as motor drive and threaded lifting rods. This adjustment method is not only fast and accurate, but also can maintain the consistency of each adjustment, thereby improving the nursing efficiency. At the same time, automated operation also reduces the impact of human factors on the nursing effect, making the nursing process more standardized and normalized, thereby improving the quality of nursing. This is undoubtedly a blessing for patients who need to stay in bed for a long time, allowing them to enjoy more professional and efficient nursing services.

[0017] The folding structure of the home care bed adopts auxiliary structures such as stable lifting rods and buffer springs to ensure the stability of the bed during the lifting process and avoid safety hazards such as shaking and tilting. The toilet hole lifting device, turning device, leg lifting device and back lifting device also adopt stable structures such as hinged connectors and rotating mounting rods to ensure the stability and reliability of various functions during the automated operation process.

[0018] The folding structure of the home nursing bed can regularly assist patients in turning over and avoiding complications such as bedsores caused by long-term bed rest. The leg lifting device and back lifting device adjust the height of the patient's legs and back respectively, which helps to improve the patient's blood circulation and respiratory function and prevent complications such as muscle atrophy and lung infection. At the same time, the automated operation of these functions also reduces the workload of nursing staff, allowing them to devote more energy to the patient's rehabilitation care, thereby improving the rehabilitation effect.

[0019] The folding structural components of the home nursing bed are all designed to be detachable, which is convenient for users to clean and disinfect. At the same time, the internal structure of the nursing bed also adopts a modular design, allowing maintenance personnel to easily disassemble and replace damaged parts, reducing maintenance costs.

[0033] Working principle: The present invention provides a folding structure for a home nursing bed, which integrates multiple functions and aims to provide a comprehensive nursing experience for patients, specifically: The bed lifting device makes it convenient for patients to get on and off the bed and reduces the burden on nursing staff by adjusting the height of the bed. Specifically, when the height of the bed needs to be adjusted, the lifting motor 17 is started, driving the threaded lifting rod 18 to rotate. Since the threaded lifting rod 18 is threadedly connected to the inner cavity of the lifting leg 13, the rotation of the threaded lifting rod 18 will drive the lifting leg 13 to move up and down in the lifting support column 3, thereby realizing the lifting and lowering of the bed height. When the lifting motor 17 rotates clockwise, the threaded lifting rod 18 moves upward, pushing the lifting leg 13 to rise, and the bed rises accordingly. When the lifting motor 17 rotates counterclockwise, the threaded lifting rod 18 moves downward, the lifting leg 13 drops under the action of gravity, and the bed lowers accordingly. During the lifting process, the stabilizing lifting rod 15 and the buffer spring 16 play a stabilizing support and buffering role to ensure that the bed is lifted and lowered smoothly to meet the nursing needs of different patients and improve the applicability of the nursing bed.

[0034] The toilet hole lifting device is convenient for patients to go to the toilet and improves the convenience of the nursing bed. When the toilet hole needs to be opened, the toilet hole motor 26 is started to drive the threaded rotating rod to rotate. The threaded rotating rod 1 is threadedly connected to the inner cavity of the bedpan pulling rod 22, so the rotation of the threaded rotating rod 1 will drive the bedpan pulling rod 22 to move, and the bedpan pulling rod 22 is connected to the hip support frame 23 and the bedpan support plate 28 through the hinged connecting piece 1 21 and the hinged connecting piece 25, thereby driving the movement of the hip support frame 23 and the bedpan support plate 28 to realize the opening and closing of the toilet hole. Specifically, when the toilet hole motor 26 is started, the threaded rotating rod 1 rotates to drive the bedpan pulling rod 22 to move to one side. The movement of the bedpan pulling rod 22 drives one end of the hip support frame 23 to descend to form a toilet hole space. At the same time, the toilet pull plate 24 moves with the movement of the hip support frame 23, pushing the bedpan support plate 28 and the bedpan placement frame 29 to flip downward, so that the bedpan is in a suitable position. When the toilet hole motor 26 rotates in the opposite direction, each component returns to its original position and the toilet hole is closed. The automatic opening and closing of the toilet hole is realized through a mechanical structure, which reduces the workload of nursing staff.

[0035] The turning device is used to assist the patient in turning over and prevent complications such as bedsores. When the patient needs to be turned over, the turning motor 37 is started to drive the threaded rotating rod 2 35 to rotate. The threaded rotating rod 2 35 is threadedly connected to the inner cavity of the turning driving rod 34, so the rotation of the threaded rotating rod 2 35 drives the turning driving rod 34 to move. The turning driving rod 34 is connected to the turning support plate 31 through the connecting plate 33 and the hinged connecting member 30, thereby driving the movement of the turning support plate 31 to realize the turning of the patient. Specifically, when the turning motor 37 is started, the threaded rotating rod 2 35 rotates to drive the turning driving rod 34 to move to one side; the movement of the turning driving rod 34 drives one end of the connecting plate 33 and the turning support plate 31 to rise or fall; the support plate support roller 1 32 rolls with the movement of the turning support plate 31 to reduce friction resistance; when the turning motor 37 rotates in the reverse direction, each component returns to its original position, and the patient completes the turning action. The automation of turning is realized through the mechanical structure, which reduces the workload of the nursing staff.

[0036] The leg lifting device adjusts the height of the patient's legs to facilitate nursing staff to perform leg care or treatment. When the height of the patient's legs needs to be adjusted, the leg lifting motor 40 is started to drive the threaded rotating rod 3 41 to rotate. The threaded rotating rod 3 41 is threadedly connected to the inner cavity of the leg lifting drive rod 42, so the rotation of the threaded rotating rod 3 41 will drive the leg lifting drive rod 42 to move. The leg lifting drive rod 42 is connected to the leg lifting support frame 1 45 through the lifting connection 43 and the hinged connection 6 44, thereby driving the movement of the leg lifting support frame 1 45 to achieve the lifting and lowering of the patient's legs. Specifically, when the leg lifting motor 40 is started, the threaded rotating rod 3 41 rotates to drive the leg lifting drive rod 42 to move to one side; the leg lifting drive rod 42 The movement drives the lifting and lowering connecting piece 43 and one end of the leg lifting and lowering support frame 45 to rise or fall; the inclined plate 46 tilts with the movement of the leg lifting and lowering support frame 45 to keep the leg support stable; the leg lifting and lowering support frame 48 is connected to the leg support frame 62 through the hinged connection plug plate 47, and moves with the movement of the leg lifting and lowering support frame 45; when the leg lifting motor 40 rotates in the opposite direction, each component returns to its original position and the patient's leg height is restored to improve the patient's comfort and prevent leg muscle atrophy caused by long-term bed rest.

[0037] The back lifting device adjusts the height of the patient's back to facilitate nursing staff to perform back care or treatment. When the height of the patient's back needs to be adjusted, the back lifting motor 50 is started to drive the threaded rotating rod 4 51 to rotate. The threaded rotating rod 4 51 is threadedly connected to the inner cavity of the back lifting and lowering driving rod 52, so the rotation of the threaded rotating rod 4 51 drives the back lifting and lowering driving rod 52 to move. The back lifting and lowering driving rod 52 is connected to the back connecting support rod 53 through the hinged connecting piece 8 57 and the transfer connecting rod 56, thereby driving the movement of the back connecting support rod 53 to realize the lifting and lowering of the patient's back. Specifically, when the back lifting motor 50 is started, the threaded rotating rod 4 51 rotates to drive the back lifting and lowering driving rod 52 to move to one side. The movement of the back lifting and lowering driving rod 52 drives the hinged connecting piece 8 57 and one end of the transfer connecting rod 56 to rise or fall. The rotation of the transfer connecting rod 56 drives one end of the back connecting support rod 53 to rise or fall, thereby adjusting the height of the patient's back. The support plate supporting roller 2 54 rolls with the movement of the back connecting support rod 53 to reduce friction resistance. When the back lifting motor 50 rotates in the opposite direction, each component returns to its original position and the patient's back height is restored, thereby improving the patient's comfort and preventing back pressure sores caused by long-term bed rest.
