To provide a first aid treatment device especially for cars for accommodating a first aid treatment equipment having a elastic and/or refoldable mat.

The mat is essentially rectangular, and is constructed as a support for inventory of the first aid treatment equipment. For efficient utilization of a prepared stock space, and especially for maintaining a compact structural shape, the mat comprises a fastener 3 in its two longitudinal edge parts so that the mat is folded and forms a flexible container. The fastener 3 allows the mat 2 to combine the longitudinal edge parts and form a stable container.
