Description

Technical Field

[0001] This invention relates to the field of medical devices and rehabilitation nursing equipment, specifically to an integrated self-care assistive nursing bed system for people with mobility impairments. Background Technology

[0002] For users who are bedridden for extended periods, elderly, or recovering from surgery and have limited mobility, daily bed care is a demanding task. It not only requires immense physical exertion from caregivers but also significantly impacts the user's dignity and quality of life. Traditional nursing beds are relatively limited in function, typically only providing basic features such as back support and leg flexion, making it difficult to meet users' deeper needs for self-care.

[0003] In actual nursing care, issues such as helping users turn over to prevent bedsores, assisting users to sit up for eating or reading, and handling users' bowel and bladder hygiene are the core and challenging aspects of nursing work. Currently, these functions often require multiple separate devices or manual operation by caregivers. For example, turning over requires caregivers to expend a lot of physical effort to move the user, posing a high safety risk; bowel and bladder care requires the use of a bedpan, a cumbersome process that can easily cause embarrassment and discomfort for the user, while also increasing the workload of caregivers. Furthermore, cleaning after bowel movements usually requires transferring the user to the toilet or using separate cleaning equipment, a process that is extremely inconvenient.

[0004] While some multifunctional nursing beds have emerged in the existing technology, such as beds with turning or defecation functions, these functions are usually simply stacked rather than organically integrated, resulting in the following drawbacks: 1. In the field of medical devices and rehabilitation nursing equipment, functional isolation of modules such as turning over, sitting up, defecation, and cleaning is independent and lacks coordination, making it impossible to form a smooth and humane nursing process.

[0005] In the field of medical devices and rehabilitation equipment technology, the user experience is often poor. For example, the design of the defecation port often requires the user to be moved significantly or the mattress has a large opening, which affects the comfort of lying in bed; the cleaning function is also mostly external, which is inconvenient to use.

[0006] In the field of medical devices and rehabilitation nursing equipment technology, automation and integration are low. Most nursing beds fail to integrate functions such as defecation and cleaning into the bed body, still requiring a lot of manual intervention, which fails to effectively reduce the nursing burden and improve the user's self-care dignity.

[0007] Therefore, there is an urgent need for a highly integrated, automated nursing bed system that can effectively assist users in completing a series of self-care activities such as turning over, sitting up, defecating, and cleaning, so as to effectively reduce nursing pressure and significantly improve the quality of life and personal dignity of people with limited mobility. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated self-care assistive nursing bed system for people with mobility impairments. Through ingenious mechanical structure design, multiple functional modules, such as automatic turning, sitting up, leg raising, defecation assistance, and cleaning / dressing assistance, are highly integrated into a single nursing bed. This system not only effectively reduces the workload of caregivers but, more importantly, significantly improves the self-care ability, personal dignity, and quality of life of users with mobility impairments. Its various functions can operate independently or work collaboratively, achieving intelligent and humanized nursing support.

[0009] To achieve the above objectives, this invention employs the following technical solution: an integrated self-care assistive nursing bed system for people with mobility impairments. Its core innovation lies in decomposing the traditional single-function nursing bed into three distinct and collaborative independent bed modules: a diaper bed, a transfer bed, and a living bed. This "three-bedroom" layout is the fundamental feature of this system. The diaper bed is specifically designed for the user's personal hygiene. Its lower half features horizontal strip support bars and defecation holes at the ends of these bars, forming an openable defecation channel. Guide rails at the lower ends of the support bars ensure precise movement for operation. Particularly noteworthy is the design of the trouser ring, which cleverly utilizes the space between the bed frame and the horizontal strip support bars. This mechanical assistance helps people with mobility impairments put on and take off their trousers without significantly raising their bodies, greatly reducing the difficulty of care and protecting user privacy. A washer positioned on the side of the bed corresponding to the diaper bed creates a complete cleaning loop, ensuring timely and thorough hygiene.

[0010] Furthermore, turning pivots A and B serve as the main rotational fulcrums of the system, respectively supporting the overall rotation of the diaper bed and the living bed. Turning pivots C, D, and E act as auxiliary fulcrums, controlling localized posture adjustments of the diaper bed and the living bed, such as raising the back or bending the legs. This collaborative design of multiple pivots enables the system to perform complex compound movements. For example, by controlling the rotation of the diaper bed or the living bed around turning pivot A or B, the user can be lifted to turn to the side; simultaneously, combined with the movement of turning pivots C or D, the upper body angle can be adjusted during turning to prevent the user from slipping and ensure comfort. This precise pivot layout is the physical basis for achieving automated and humanized nursing movements.

[0011] Furthermore, the first degree of freedom is the rotation of the entire sitz bed around the turning axis A. This action is usually used in conjunction with a transfer bed to transfer the user between the transfer bed and the sitz bed, or to assist the user in turning over to the side. The second degree of freedom is the ability of the upper body to rotate upwards by nearly 90 degrees around the turning axis C, which is an extremely important function. When the user needs to be washed, wiped down, or have their clothes changed, raising the upper back to an angle close to a sitting position not only facilitates the operation for caregivers, but more importantly, gives the user a more autonomous and dignified posture to cooperate with care or perform short activities, such as eating or reading. This breaks the limitation of traditional nursing beds where users can only lie flat for long periods of time, effectively improving the user experience.

[0012] Furthermore, the transfer bed is not a single flat surface, but rather composed of two independent interdigitated structures. This design allows it to act as a "bridge" and "transfer platform" between the diaper bed and the living bed. One part of the interdigitated structure is linked to the movement of the diaper bed, rotating around the turning axis A; the other part is linked to the movement of the living bed, rotating around the turning axis B. When it is necessary to transfer the user from the living bed to the diaper bed, the two interdigitated structures can move in coordination, smoothly "catching" the user and "transferring" them. The entire process is smooth and continuous, avoiding the bumps and discomfort caused to the user by manual handling in traditional care, and significantly reducing the physical burden on caregivers. The interlaced design of the interdigitated structure ensures the continuity and safety of support for the user's body during transfer.

[0013] Furthermore, the multi-functional transformation capability of the living bed transcends the concept of a typical bed. The living bed can rotate as a whole around its turning axis B, primarily for use with a transfer bed to facilitate user transfer and assisted turning. Its core function lies in the fact that by rotating the upper body nearly 90 degrees upwards around the turning axis D, while simultaneously rotating the legrests nearly 90 degrees downwards around the turning axis E, the entire living bed can quickly transform into a comfortable chair. This function is of great significance, allowing users to transition from a lying to a sitting position without leaving the bed. This not only greatly facilitates daily activities such as eating, watching TV, and communicating with family while sitting in bed, but also helps promote blood circulation and respiratory function, playing a positive auxiliary role in preventing complications of prolonged bed rest such as bedsores and lung infections, significantly improving the user's quality of life.

[0014] Furthermore, the defecation hole is not simply a fixed opening, but rather achieved through precise relative movement of the strip support bars controlled by the lower guide rail assembly. In the non-use state, all the strip supports are closely aligned, forming a complete and flat bed surface, ensuring user comfort. When defecation is needed, the control system instructs the guide rail assembly to move, causing some of the strip supports to separate or sink, thus forming a sufficiently large hole (i.e., the defecation hole) in the center of the support surface. After use, the support bars close again. This dynamic opening and closing design ensures functionality while maximizing the normal usability of the bed surface, avoiding the discomfort and safety hazards that a fixed defecation hole might cause, reflecting meticulous attention to detail in the design.

[0015] Furthermore, the ring frame is designed to move horizontally within a specific track between the bed frame and the transverse support strips. Its working path is from the user's feet towards their waist, or vice versa. When the user needs to put on trousers, the trousers can be pre-attached to the ring frame, which then moves from the feet to the waist, thus "putting on" the trousers. Removing trousers is the reverse process. This mechanized process replaces the laborious step of lifting the user's hips or legs in traditional care, which is especially important for heavier users or less physically capable caregivers. It directly addresses the challenge of putting on and taking off trousers in daily care, providing a labor-saving, efficient, and dignified solution.

[0016] Furthermore, in addition to coordinating movement to form the drainage hole, these strip supports are also endowed with the ability to sink independently. This means the control system can instruct one or more support strips to descend individually, creating a localized, controllable recessed area on the commode bed's support surface. This feature has multiple uses: for example, when washing the buttocks, the slight recess helps to collect water, improving washing efficiency and preventing splashing; when providing care for users at risk of pressure sores, the controllable recess can temporarily relieve pressure on specific body parts and promote blood circulation. This programmable ability to adjust the local shape allows the commode bed to adapt to more complex and personalized care needs.

[0017] Furthermore, the washer is not placed arbitrarily, but is fixedly installed on the side of the bed frame, and its position must precisely correspond to the area above or to the side of the sitz bed. This layout ensures that once the user is transferred to the sitz bed and the toilet opening is opened, the washer can immediately begin operation, with its nozzle or cleaning arm able to unobstructedly rinse, dry, and even disinfect the user with warm water. This integrated design guarantees the timeliness and privacy of the cleaning process, eliminating the need for the user to be moved to a separate bathing facility, achieving "bedtime cleanup" and creating an efficient and hygienic personal care space.

[0018] Furthermore, by controlling the rotation of the commode bed around turning axis A and the living bed around turning axis B at specific angles, the system can support the user's body and smoothly complete leftward or rightward turning movements. This is crucial for the health care of long-term bedridden individuals. Regular and standardized turning can effectively distribute body pressure and is one of the most effective measures to prevent pressure sores. The automated turning function frees caregivers from heavy physical labor and ensures that the frequency and angle of turning are more scientific and accurate, thereby greatly improving the professionalism and reliability of care and protecting the user's health.

[0019] This invention provides an integrated self-care assistive nursing bed system for people with mobility impairments, which has the following beneficial effects: 1. This nursing bed system integrates a three-bed design—a bed-washing bed, a transfer bed, and a living bed—achieving functional zoning and seamless connection, significantly improving the self-care efficiency of individuals with mobility impairments. The bed-washing bed is specifically for defecation and cleaning, the transfer bed assists with body transfer, and the living bed provides daily rest and activity support. This zoning design allows users to quickly switch between different needs without frequent movement or reliance on caregivers, such as directly transitioning from a resting state to a defecation procedure, reducing physical burden and waiting time. Simultaneously, the collaborative operation of the three beds reduces the risk of cross-infection, as the bed-washing area is relatively isolated from other areas, maintaining an overall hygienic environment. Furthermore, this integrated layout optimizes space utilization, enabling the nursing bed to be multifunctional within a limited area, enhancing user autonomy and quality of life.

[0020] The horizontal support strips and guide rails beneath the commode bed, combined with the drainage hole, provide a safe and comfortable defecation experience. The support strips can be controlled to sink and create localized recesses, which, combined with the relative movement of the guide rails, allow the drainage hole to be flexibly adjusted in size and position to precisely adapt to the user's body contours. This avoids the inconvenience of using a bedpan or manually moving the user, as required by traditional nursing beds, reducing friction and discomfort. Simultaneously, this design allows users to defecate without changing their position, reducing the risk of falls or injury. The side-mounted washer further enables instant cleaning, maintaining personal hygiene and enhancing the user's dignity and mental well-being, as the user can handle their bodily needs more privately and independently.

[0021] The circular trouser holder greatly simplifies the process of changing trousers, especially for those with limited mobility. This holder moves horizontally from the feet to the waist, operating within the space between the bed frame and the transverse support bars, allowing users to easily put on and take off trousers while lying down. This design avoids the physical exertion and potential dangers of frequent turning over or sitting up, reducing the need for caregiver intervention. Users can change clothes with simple controls, enhancing self-care ability and reducing clothing wear and tear or physical injury caused by limited mobility. Furthermore, the circular structure of the holder ensures a smooth fit for trousers, improving comfort and enhancing user confidence and convenience during daily care.

[0022] The configuration of multiple turning axes (such as turning axes A, B, C, D, and E) allows the bed to rotate at multiple angles, effectively assisting users in side-turning and sitting-up movements. For example, the commode bed and living bed can rotate around their axes, turning the user's body to the left or right, preventing bedsores and muscle atrophy; the living bed can also be converted into a chair, promoting blood circulation and lung expansion. This active turning function reduces complications from prolonged bed rest, enhances physical mobility, and can be performed by the user without external assistance, reducing the intensity of care. At the same time, the interdigital structure of the transfer bed further optimizes the smoothness of body transfer, avoiding discomfort caused by sudden movements, thereby improving safety and comfort.

[0023] The bed's design allows it to transform into a chair-like position. Through the coordinated rotation of pivots D and E, the upper body tilts upwards by nearly 90 degrees and the legs downwards by nearly 90 degrees, mimicking a seated posture. This facilitates the transition from a lying to a sitting position for eating, reading, or social activities, promoting physical recovery and psychological well-being. The transformation is smooth and controllable, reducing dizziness or discomfort caused by changes in posture, while the bed frame provides stable support to prevent slippage. This multifunctional design extends the user's activity time, reduces the feeling of confinement from prolonged bed rest, and encourages light exercise, thereby improving overall quality of life and self-care ability.

Detailed Implementation

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Overall Structure and Basic Operation of Integrated Self-Care Assisted Nursing Bed System This embodiment details the overall configuration and workflow of an integrated self-care assistive care bed system for people with mobility impairments. The system is based on a bed frame 1, whose lower end is stably supported on the ground by support columns 2, ensuring overall structural stability. The bed frame 1 integrates three independent bed sections: a diaper bed 3, a transfer bed 4, and a living bed 5. The diaper bed 3 is located on one side, and its lower half is equipped with a transverse strip support group 6. This support group consists of multiple movable strip components, with a defecation hole 7 at each end for waste disposal. A guide rail group 8 is installed at the lower end of the transverse strip support group 6, allowing the support strips to slide relative to each other to adjust the size and position of the defecation hole 7. A trouser ring frame 9 is located between the bed frame 1 and the transverse strip support group 6. This ring frame can move horizontally to assist the user in changing clothes. A washer 10 is fixed to the side of the bed frame 1, corresponding to the position of the diaper bed 3, for cleaning operations. In practical use, users can select different modes via the controller (not mentioned in the claims, but necessary for the function): for example, when defecation is needed, the user moves to the commode bed 3, and the transverse strip support group 6 is adjusted via the guide rail group 8 to form the defecation hole 7, while the washer 10 automatically rinses and dries; when transfer is needed, the interdigitated structure of the transfer bed 4 works in concert to smoothly transfer the user to the living bed 5 for rest. The entire system achieves seamless switching through mechanical linkage, significantly reducing the burden of care and improving the user's self-care ability.

[0029] Example 2: Realization of defecation and cleaning functions of the bidet bed This embodiment focuses on the specific operation of the commode bed 3, aiming to help people with mobility impairments independently complete the defecation and cleaning process. As one of three bed units, the key structural feature of the commode bed 3 is the transverse strip support group 6, which consists of multiple high-strength strip components arranged in parallel. These components can move relative to each other via the lower guide rail group 8. When the user needs to defecate, the system activates the commode mode: some of the strip components in the transverse strip support group 6 slide in a controlled manner, forming a defecation hole 7 in the center of the bed surface. The size of this hole is adjustable to accommodate different user needs. Simultaneously, the commode bed 3 can rotate as a whole around the turning axis column A11, or its upper body can rotate upwards by nearly 90 degrees around the turning axis column C13, placing the user in a semi-sitting position for easier defecation. A collection device can be connected below the defecation hole 7, not mentioned in the claims, but commonly used in practice. After completion, the washer 10 automatically starts. This washer, installed on the side of the bed frame 1, includes water spraying and drying functions and can be aimed at cleaning the user's buttocks. Furthermore, the horizontal support strips in strip group 6 can sink independently, creating localized recessed areas to prevent pressure on the user's skin and enhance comfort. The entire process requires no manual intervention; users can control it via bedside buttons or a remote control, effectively protecting personal privacy and dignity.

[0030] Example 3: Side-rolling assistance mechanism based on a rollover pivot post This embodiment details how the system enables a user to turn to the side via multiple turning pivots, preventing bedsores and improving comfort. Turning pivots A11 and B12 are located at the inner end of the bed frame 1. Additionally, a turning pivot C13 is located between the bed frame 1 and the washroom bed 3, and turning pivots D14 and E15 are located between the bed frame 1 and the living bed 5. When the user needs to turn to the left, the washroom bed 3 rotates around turning pivot A11, while the interdigitated structure of the transfer bed 4 intervenes: the transfer bed 4 consists of two independent interdigitated parts; one part supports the user's upper body and rotates around turning pivot A11, while the other part supports the lower body and rotates around turning pivot B12, working together to smoothly turn the user to the side. Similarly, the living bed 5 can rotate around turning pivot B12, adjusting its angle in conjunction with turning pivots D14 and E15. For example, when a user is lying on the living bed 5, they can control the turning pivot D14 to rotate their upper body upwards, or use the turning pivot E15 to bend their legs downwards, assisting in the turning process. The movement is smooth and adjustable, and users can trigger turning with simple commands, reducing the health risks associated with prolonged bed rest. This mechanism emphasizes safety, with the pivots designed with a locking function to prevent accidental movement.

[0031] Example 4: Pants changing operation aided by a trouser ring rack on a washstand This embodiment describes the application of a trouser ring frame 9 on a washbed 3, specifically designed to help people with mobility impairments easily change their trousers. The trouser ring frame 9 is positioned within the space between the bed frame 1 and the transverse strip support group 6. Its structure is a ring frame that can move horizontally from the user's feet towards their waist. When the user needs to change trousers, they first adjust the washbed 3 to a suitable posture, for example, by slightly raising their upper body using the turning pivot C13. Then, the trouser ring frame 9 starts moving, slowly sliding from the foot of the bed to the head. During this process, its ring structure supports the trouser opening, allowing the user to easily remove or put on the trousers by slightly lifting their hips or cooperating with the frame's movement. The strip supports of the transverse strip support group 6 can be independently lowered, creating a localized recess to provide the user with extra space to prevent jamming. The entire operation is performed on the washbed 3 without interfering with the function of the defecation hole 7; for example, cleaning can be performed before changing trousers to ensure hygiene. The movement of the trouser ring frame 9 is controlled by a guide rail and a motor, as implied in the claims, and its speed is adjustable to accommodate different user abilities. This design significantly reduces the difficulty of changing clothes, making it especially suitable for people with limb weakness and promoting self-care ability. At the same time, caregivers can assist rather than do it entirely, improving efficiency.

[0032] Example 5: Conversion of a living bed into a chair and its daily use This embodiment illustrates how the living bed 5 transforms into a chair-like form via a rotating pivot, meeting the user's sitting posture needs, such as for eating or reading. The living bed 5, serving as the resting area among the three bed sections, can rotate as a whole around the turning pivot B12. Its key function lies in modular adjustment: the upper body can rotate upwards nearly 90 degrees around the turning pivot D14, raising the back; simultaneously, the legs can rotate downwards nearly 90 degrees around the turning pivot E15, allowing the lower legs to hang naturally, thus transforming the entire living bed 5 from a lying position into a comfortable chair-like form. During the transformation, the bed surface material possesses a certain degree of resilience, ensuring a natural and pressure-free user posture. For example, when the user triggers the transformation via a controller, pivots D14 and E15 move synchronously, gradually adjusting the angle. The interdigitated structure of the intermediate bed 4 provides support when needed, preventing slippage. After the transformation, the user is in a stable sitting posture, facilitating daily activities; the supporting pillars 2 of the bed frame 1 ensure overall stability. Furthermore, this chair-like form can be combined with other functions; for example, after cleaning the washroom bed 3, the user can move to the living bed 5 to sit and rest. This design enhances the user experience, reduces reliance on additional wheelchairs, and promotes freedom of movement indoors.

[0033] Example 6: The patient takes a bath while on the sitz bed. When it is necessary to clean the body of a bedridden person with limited mobility, the caregiver or the patient can activate the "bathing" mode of the nursing bed through the control system. First, the patient lies on the bedpan 3. The system controls the upper part of the bedpan 3 to rotate and rise nearly 90 degrees around the turning axis C13, changing the patient from a supine position to a comfortable sitting position, preparing for the subsequent bathing.

[0034] When bathing begins, the horizontal strip support group 6 located below the commode bed 3 starts to work. The guide rail group 8 below it moves relative to each other, causing some of the strip supports to sink in a controlled manner, thereby forming a localized, body-fitting concave area on the bed surface corresponding to the patient's buttocks and back. The center of this concave area is aligned with the defecation hole 7, together forming a temporary "bathtub" structure for accumulating water.

[0035] Simultaneously, the washer 10, installed on the side of the bed frame 1 corresponding to the position of the commode bed, is activated. The washer extends its spray arm, spraying hot water at a suitable temperature and mild bath liquid. Nursing staff can hold the spray arm or set an automatic program to give the patient a full-body rinse. Used wastewater flows into the pre-set wastewater collection system under the bed through the gaps between the strip supports and the defecation hole 7.

[0036] After washing, the washer 10 can be switched to warm air function, blowing comfortable warm air to dry the patient's body, ensuring the skin is dry and preventing chills. During the bathing process, if changing clothes is necessary, the trouser loop 9 can be moved horizontally from the foot of the bed to the patient's waist, assisting the patient in easily putting on and taking off trousers, greatly improving the convenience and humanization of the bathing process. This integrated design allows people with limited mobility to complete a thorough personal cleaning without leaving the bed, significantly reducing the burden of care and maintaining the patient's dignity.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
