Description

Technical Field

[0001] The utility model relates to the technical field of stretcher beds, and more specifically, to a detachable stretcher bed. Background Art

[0002] In current technology, stretcher beds are an important medical device and are often used in hospitals, emergency centers, and other places where patients need to be moved quickly. The design of a stretcher bed usually includes a bed body, legs, and rollers, among which the legs and rollers are the key parts to ensure the flexibility and stability of the stretcher bed. However, in the prior art, the lower legs and rollers of the stretcher bed are often not designed to be flexible enough and cannot be easily disassembled and adjusted.

[0003] First, the non-adjustability of the legs limits the height adaptability of the stretcher. In different rescue or treatment scenarios, the height of the stretcher may need to be adjusted to suit different environments and patient needs. For example, in emergency medical rescue, the stretcher may need to be lowered to make it easier to move the patient, or the height may need to be adjusted during treatment to facilitate the operation of medical staff. However, this flexibility is limited because the legs of existing stretchers are not easy to adjust.

[0004] Secondly, the fixed design of the rollers affects the storage convenience of the stretcher. When not in use, the stretcher needs to be stored in a suitable location for quick access. However, since the rollers cannot be easily removed, these stretchers take up a large storage space, which not only increases the demand for storage space, but may also affect the space utilization efficiency of hospitals or emergency centers.
