Having used this type of litter during exercises, I noted a key feature are the wooden/ bamboo slats in the backside. These are fitted so a patient can be strapped in the litter and be manhandled out of tight spaces, while keeping the patient straight.

Noteworthy is that these litters cannot be folded lengthwise, as it would defy their purpose. So this cannot be the same item as shown on Jakko's photos.
