Description

Technical Field

[0001] The present invention relates to the technical field of nursing bed equipment, and in particular to an intelligent nursing wheelchair bed with cleaning and sanitation functions and a nursing method. Background Art

[0002] A wheelchair bed is a medical assistive device that combines the functions of a wheelchair and a bed. It is primarily used by people with limited mobility, such as the elderly, the disabled, those recovering from surgery, and those with paralysis. It can easily convert from a bed to a wheelchair, or vice versa, allowing users to switch between bed and wheelchair, enabling free movement and rest. The wheelchair bed also accommodates urination and defecation needs and features hygienic cleaning functions such as heating, flushing, and drying.

[0003] Existing wheelchair beds combine the functions of beds and wheelchairs. The overall structure is usually more complex and the volume is significantly larger than that of ordinary hospital beds or wheelchairs, which makes it difficult to flexibly place them in small spaces (such as family bedrooms and old wards). At the same time, the wheelchair and bed are mostly separated, which cannot effectively increase the connectivity between the wheelchair and the bed and the support for the bed. When converting the wheelchair bed into a bed-chair, the caregiver needs to manually operate multiple parts (such as folding the bed board and adjusting the wheelchair wheel group). The process is cumbersome and time-consuming. If the operation is improper, it may cause the user to shake or feel uncomfortable. At the same time, the force point on one side of the wheelchair bed is located on the electric wheelchair, which makes it difficult to support the electric wheelchair when the wheelchair is converted into a bed. In addition, most wheelchair beds only have basic bed-chair conversion functions and lack additional nursing functions. For this reason, we propose an intelligent nursing wheelchair bed with cleaning and sanitation functions and a nursing method. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent nursing wheelchair bed and nursing method with cleaning and sanitation functions, so as to solve the many limitations of some existing wheelchair beds in use as mentioned in the above background technology: because the wheelchair and the bed are mostly split, it is difficult to support the bed with the wheelchair when connecting the wheelchair and the bed. At the same time, when the wheelchair bed is converted from a bed to a chair, it needs to rely on manual operation of the nursing staff, which makes it difficult for the patient to use it by himself. At the same time, the wheelchair does have additional nursing functions.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent nursing wheelchair bed with cleaning and sanitation functions and a nursing method, comprising a bed head, a bed board, a connecting block, and a wheelchair body, wherein a support column is installed at the bottom of the connecting block and a mattress is installed at the top of the bed board; and further comprising: The support assembly is arranged at the bottom of the bed board and provides auxiliary support to the bed board through the support assembly; The anti-dumping component is arranged on the right side of the wheelchair body, and supports the bottom of the wheelchair body through the anti-dumping component; The back rotating assembly is arranged on the left side of the top of the wheelchair body and supports the user's back through the back rotating assembly; The leg rotation assembly is arranged on the right side of the top of the wheelchair body and supports the user's legs through the leg rotation assembly; The opening and closing component and the nursing component are arranged on the top middle side of the wheelchair body and are opened and closed by the opening and closing component.

[0012] Among them, the nursing component includes a limit block, the top of the limit block is slidably connected to a collection frame, and a pulling handle is installed on the outside of the collection frame.

[0013] Among them, the flushing component includes a water pump, and a flushing ring is arranged inside the care component.

[0014] Among them, the jacking component includes a screw motor, and the output end of the screw motor is fixedly connected to a rotating screw, the jacking component is internally slidably connected to a limit rod, and the bottom of the limit rod is fixedly connected to a fixed seat, and a moving wheel is installed at the bottom of the fixed seat.

[0015] The present invention also aims to provide a method for caring for an intelligent nursing wheelchair bed with a cleaning and sanitation function, using any of the above-described intelligent nursing wheelchair beds with a cleaning and sanitation function, and the specific steps are as follows: S1: When the user needs to perform excretion care, operate the controller to rotate the rotating plate of the opening and closing component through the damping shaft, driving the bottom connecting rod and the toilet cover to open, exposing the excretion area below. The damping shaft can keep the rotating plate stable at any angle, which is convenient for users to use.

[0016] S2: After the user defecates, the waste falls into the collection box, completing the waste collection. Pull the handle of the collection box to pull it out for cleaning, replace the garbage bag, and clean the collection box.

[0017] S3: Start the water pump of the flushing component. The water pump delivers water to the flushing ring inside the care component. The water outlet on the flushing ring sprays water to the excretion area to flush away residual dirt. The water pressure of the water pump is adjusted through the controller to achieve the best flushing effect and maintain hygiene.

[0018] S4: If the wheelchair is converted into a bed, the support assembly will provide auxiliary support for the bed board. At the same time, the back and leg rotation assemblies will drive the angle adjuster through the angle motor to synchronously adjust the angle of the fixed plate and the cushion, quickly completing the form conversion from bed to wheelchair, reducing operation time and the risk of shaking for the user.

[0019] S5: If the wheelchair bed needs to be stationary, operate the controller to start the jacking assembly, the screw motor drives the rotating screw to rotate, and the limit rod slides inside the jacking assembly, driving the fixed seat and the movable wheel to descend and lift up, so that the rotating wheel is off the ground to prevent the tire from being deformed or the wheel from being damaged by debris on the ground due to long-term stationary. When the wheelchair bed needs to be moved, operate the controller to reverse the screw motor, the fixed seat descends, the movable wheel is off the ground, the rotating wheel contacts the ground, and the movement of the wheelchair bed is restored.

[0020] The present invention has at least the following beneficial effects: When the present invention is in use, the back and leg rotating components drive the angle adjuster through the angle motor to synchronously adjust the angle of the fixed plate and the cushion, quickly completing the form conversion from bed to wheelchair, without the need for caregivers to manually fold or adjust, reducing operation time and the risk of user shaking. At the same time, the reinforcement plate and support block of the support component provide central support during conversion, cooperating with the support of the handle to avoid instability of the bed body caused by the middle part being suspended in the air, thereby enhancing structural reliability. The rotating plate of the opening and closing component controls the opening and closing of the toilet lid through a damping shaft. The collection frame of the nursing component can be pulled out to replace the garbage bag. The water pump of the flushing component drives the flushing ring to spray water, forming an integrated nursing process of waste collection and automatic flushing, reducing the workload of nursing staff for manual cleaning. At the same time, the medical universal wheels automatically contact the ground to form a support point to prevent the wheelchair from tipping over backwards. The jacking component lifts the rotating wheels off the ground when stationary and supports them with moving wheels, which not only protects the tires but also improves static stability, adapting to the safety needs of different scenarios. Finally, the user's urination and defecation needs can be met on the wheelchair bed, and it also has hygienic cleaning functions such as heating, flushing and drying. This can reduce the burden on caregivers and allow caregivers to go to the bathroom at night without accompanying the user. At the same time, the user does not need to go back and forth to the bathroom at night, allowing most users to take care of themselves. BRIEF DESCRIPTION OF THE DRAWINGS

The damping shaft 802 can be used to keep the rotating plate 801 stable at any angle, which is convenient for users to use.

[0028] S2: After the user defecates, the waste falls into the collection box 902, completing the waste collection. Pull the pull handle 903 of the collection box 902 to pull it out for cleaning, replace the garbage bag, and clean the collection box 902.

[0029] S3: Start the water pump 1101 of the flushing component 11. The water pump 1101 transports water to the flushing ring 1102 inside the care component 9. The water outlet on the flushing ring 1102 sprays water into the excretion area to flush away residual dirt. The water pressure of the water pump 1101 is adjusted through the controller 1003 to achieve the best flushing effect and maintain hygiene.

[0030] S4: If the wheelchair is converted into a bed, the bed board 101 is auxiliary supported by the support component 3. At the same time, the back and leg rotation component 7 drives the angle adjuster through the angle motor to synchronously adjust the angle of the fixed plate and the cushion, quickly completing the form conversion from bed to wheelchair, reducing operation time and the risk of user shaking.

[0031] S5: If the wheelchair bed needs to be stationary, the operation controller 1003 starts the jacking assembly 12, the screw motor 1201 drives the rotating screw 1202 to rotate, and the limit rod 1203 slides inside the jacking assembly 12, driving the fixed seat 1204 and the movable wheel 1205 to descend and lift up, so that the rotating wheel 503 is off the ground to prevent long-term static conditions from causing tire deformation or ground debris to damage the wheel. When the wheel 1205 chair bed needs to be moved, the operation controller 1003 reverses the screw motor 1201, the fixed seat 1204 descends, the movable wheel 1205 is off the ground, and the rotating wheel 503 contacts the ground to resume the movement of the wheelchair bed.

[0032] Example 2 In the second embodiment, other structures remain unchanged.

11. A method for caring for an intelligent nursing wheelchair bed with cleaning and sanitation functions, characterized by: The specific steps of using the intelligent nursing wheelchair bed with cleaning and sanitation functions as described in any one of claims 1 to 10 are as follows: S1: When the user needs to perform excretion care, operate the controller to rotate the rotating plate of the opening and closing component through the damping shaft, driving the bottom connecting rod and the toilet cover to open, exposing the excretion area below. The damping shaft can keep the rotating plate stable at any angle, which is convenient for users to use. S2: After the user defecates, the waste falls into the collection box, completing the waste collection. Pull the handle of the collection box to pull it out for cleaning, replace the garbage bag, and clean the collection box. S3: Start the water pump of the flushing component. The water pump delivers water to the flushing ring inside the care component. The water outlet on the flushing ring sprays water to the excretion area to flush away residual dirt. The water pressure of the water pump is adjusted through the controller to achieve the best flushing effect and maintain hygiene. S4: If the wheelchair is converted into a bed, the support assembly will provide auxiliary support for the bed board. At the same time, the back and leg rotation assemblies will drive the angle adjuster through the angle motor to synchronously adjust the angle of the fixed plate and the cushion, quickly completing the form conversion from bed to wheelchair, reducing operation time and the risk of shaking for the user. S5: If the wheelchair bed needs to be stationary, operate the controller to start the jacking assembly, the screw motor drives the rotating screw to rotate, and the limit rod slides inside the jacking assembly, driving the fixed seat and the movable wheel to descend and lift up, so that the rotating wheel is off the ground to prevent the tire from being deformed or the wheel from being damaged by debris on the ground due to long-term stationary. When the wheelchair bed needs to be moved, operate the controller to reverse the screw motor, the fixed seat descends, the movable wheel is off the ground, the rotating wheel contacts the ground, and the movement of the wheelchair bed is restored.
