Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a multifunctional detachable nursing bed chair. Background Technology

[0002] With the increasing aging of the population, the aging problem has become a serious challenge that my country cannot ignore. According to data from the Seventh National Population Census, in 2020, the proportion of people aged 65 and above in China reached 13.5%, with a total elderly population of 190 million. Addressing the aging population has become part of China's development strategy. It is projected that by 2053, the elderly population will reach a peak of approximately 487 million, accounting for 34.9% of the total population at that time, making my country a super-aged society. According to my country's population census results and UN data, the aging of the population will continue, and home-based elderly care and rehabilitation nursing will become common needs for many families. Daily care for disabled elderly and people with disabilities faces many difficulties, especially in transferring them from bed and using the toilet, which leads to a growing demand for nursing beds and transfer equipment.

[0003] Existing technologies include integrated nursing devices that combine a nursing bed and a wheelchair. These devices can take the form of a bed, allowing patients to lie down and recuperate; they can also transform into a wheelchair, facilitating patient transfer and toileting, thus achieving multiple functions.

[0004] The nursing bed is designed to allow for wheelchair transfer from either the side or the middle. Since the user is primarily lying in the middle of the bed, a wheelchair transfer from the side requires a second transfer by the caregiver, increasing their workload and potentially causing further injury. A wheelchair transfer from the middle requires a larger turning space. Summary of the Invention

The limiting support frame 86 can play a limiting support role for the deflection seat 81.

[0048] As a preferred embodiment, the roller shaft 84 includes an inner shaft and an outer cylinder. The outer cylinder is rotatably mounted on the inner shaft, and one end of the inner shaft is hinged to the rotating ring 82. When not in use, the roller shaft 84 can be bent toward the end face of the rotating ring 82 to reduce its volume. More preferably, a groove for accommodating the roller shaft 84 can be formed on the end face of the rotating ring 82.

[0049] In addition, the leg plate drive mechanism 62 in this embodiment can be replaced by a linkage drive assembly. One end of the linkage drive assembly is hinged to the frame 3, and the other end of the linkage drive assembly is hinged to the leg plate 24. There are two sets of linkage drive assemblies, which are assembled in parallel and symmetrically. Each set of linkage drive assemblies includes two links. When the two links are collinear, they can provide stable support for the leg plate 24.

[0050] Example 3

[0051] This embodiment is basically the same as Embodiment 1, except that, as Figure 8 As shown, a toilet board 232 can be installed inside the toilet hole 231. The toilet board 232 can be hinged. When there is no need to use the toilet, the toilet board 232 is embedded in the toilet hole 231 to support the user. When it is necessary to use the toilet, the toilet board 232 can be tilted open to facilitate toilet use.

[0052] As a preferred embodiment, the toilet seat 232 opens and closes under the action of the toilet seat opening and closing mechanism 9. The toilet seat opening and closing mechanism 9 is assembled on the lower surfaces of the toilet seat 232 and the seat 23. The mechanism includes an opening / closing electric actuator 91, a flipping actuator 92, a transmission connecting rod 93, a support rod 94, and a support frame 95. The opening / closing electric actuator 91 is assembled on the lower surface of the seat 23. The flipping actuator 92 is arranged parallel to the hinge axis of the toilet seat 232, and both ends of the flipping actuator 92 are connected to the hinge axis of the toilet seat 232 via connecting plates. The support rod 94 is slidably assembled on the lower surface of the toilet seat 232, and the support frame 95 is fixedly assembled. On the lower surface of the seat 23, a support groove is formed between the upper surface of the support frame 95 and the lower surface of the toilet 232. The support rod 94 can slide into the support groove of the support frame 95 to be supported by the support frame 95. The telescopic end of the opening and closing electric push rod 91 is hinged to one end of the transmission link 93 through the connecting block 96. The other end of the transmission link is hinged to the support rod 94. An elongated hole is provided on the connecting block 96. The flip push rod 92 passes through the elongated hole. An elastic element 97 is provided in the elongated hole. The elastic element 97 acts on the flip push rod 92. When the toilet seat 232 needs to be opened, the opening / closing electric actuator 91 retracts. The actuator 91, through the connecting block 96 and the transmission link 93, drives the support rod 94 to slide away from the support frame 95, causing the toilet seat 232 to disengage from the support frame 95. The actuator 91 further retracts, driving the tilting actuator 92 downwards through the connecting block 96. The tilting actuator 92 rotates the hinge shaft of the toilet seat 232, causing the toilet seat 232 to tilt downwards and open. When the toilet seat 232 needs to be closed, the actuator 91 extends. The actuator 91, through the connecting block 96, pushes the tilting actuator 92 upwards, causing the hinge shaft of the toilet seat 232 to rotate, causing the toilet seat 232 to tilt upwards and close. The actuator 91, through the connecting block 96 and the transmission link 93, drives the support rod 94 to slide towards the support frame 95. The support rod 94 extends into the support groove of the support frame 95, and the toilet seat 232 is stably supported by the support frame 95. Preferably, there are two support rods 94 arranged in parallel, connected at the middle by a crossbar. A transmission link 93 is hinged to the middle of the crossbar, allowing the two support rods 94 to slide synchronously. More preferably, a limiting protrusion may be provided on the support rod 94 to limit its sliding range. The elastic element 97 may be, but is not limited to, a spring.
