  • Patent number: 4345591
    Abstract: A wound dressing for use in first aid is described comprising a bandage to which is secured, by two parallel seams, a compress. The compress has flaps which can be folded over the region between the two seams, or which can be opened out. An open mouthed pocket is defined between the two seams which can accommodate a rigid body, such as a rolled bandage, to enable the wound dressing to be utilised to staunch a flow of blood. With the rolled bandage removed from the pocket and the flaps opened out, the wound dressing may be utilised to dress a large wound, such as a burn.
