Description

Technical Field

[0001] The utility model belongs to the technical field of nursing equipment, and in particular relates to a dual-purpose bed for wheelchair and nursing. Background Art

[0002] When caring for elderly patients and patients with limited mobility, it is often necessary to transfer the patients to other places. When using common nursing equipment such as nursing beds and wheelchairs, the patients cannot complete the transfer smoothly by their own ability and need the additional help of caregivers to complete the transfer.

[0003] In response to these problems encountered in clinical nursing, there are already related technologies to assist patients in transferring between beds and wheelchairs and improve reliability. For example, the Chinese patent application number 202120196120.9 published on March 25, 2022, records a wheelchair and nursing bed with bed-chair alignment and automatic locking structure. When transferring patients from wheelchairs to nursing beds, the wheelchair and nursing beds are docked and fixed to ensure the stability between the wheelchair and nursing beds during the patient transfer process. However, this technical solution takes up a lot of space and is inconvenient to store; on the other hand, the bed-chair alignment and automatic locking structure used to connect the nursing bed and wheelchair only ensures a temporary connection, and does not guarantee the stability of the connection under stress.
