What is the common name for the rigid stretcher used in technical and water rescues, which allows water to drain through holes in the bottom?

The common name for the rigid stretcher used in technical and water rescues that allows water to drain through holes in the bottom is indeed the basket stretcher. This type of stretcher is designed to provide optimal support and stability for patients in challenging environments, such as in water or rugged terrain. The design features openings or mesh that facilitate the drainage of water, preventing pooling, which is particularly important in rescue scenarios to ensure the patient remains as comfortable and dry as possible during transport. The basket stretcher's rigid structure ensures that the patient is securely held in place, which is critical for minimizing further injury during the rescue process. It is also versatile, allowing for use in a variety of rescue situations, including over rough ground, through narrow passages, or in water, thus making it a preferred choice among rescue professionals.
