Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an integrated dual-purpose wheelchair stretcher. Background Technology

[0002] In time-sensitive scenarios such as pre-hospital emergency care, in-hospital transport, and special rescues, the rapid, safe, and stable movement of the injured and sick is not only crucial for ensuring treatment efficiency but also a key factor in determining treatment outcomes. Currently, emergency transport equipment mainly relies on traditional stretchers and flatbeds. However, these conventional devices have many significant shortcomings in practical applications, especially in transporting patients in complex environments.

[0003] Most existing emergency stretchers are fixed-frame structures, large in size, and cannot be folded or deformed. In confined spaces such as narrow residential building corridors, elevator cars, and high-rise apartment building corridors, heavy stretchers often cannot pass smoothly or even enter the area, requiring a lot of manpower and time to move them or adjust their position multiple times, seriously delaying precious rescue time and increasing the risk of secondary injury. Traditional stretchers usually only provide a single supine position and cannot be flexibly adjusted according to the patient's specific injury or condition, making it difficult to meet the comfort and therapeutic positioning needs of different patients at different stages of treatment. Traditional stretchers cannot provide a sitting position similar to a wheelchair, and the process of transferring patients from stretchers to wheelchairs or hospital beds is inconvenient and risky. Furthermore, they lack integrated assistive function platforms and safety call systems that allow patients to actively send out help signals during transport, posing safety hazards when no one is present or when medical staff are temporarily absent.
