Stretcher hospital beds are primarily designed for transporting patients who require medical attention. They are equipped with features that ensure the patient is secure and stable during transit. For instance, these beds often come with adjustable side rails that can be raised to prevent accidental falls, and sturdy straps that help secure the patient safely. This is particularly important for patients who may be unconscious, immobile, or in significant pain, as any sudden movement can exacerbate their condition.
