Problems solved by technology

However, a disadvantage of the prior art is that, in use, the flutter valve may become blocked by blood, resulting in a reduced ability of the dressing to provide an outlet for air and bodily fluids
Also, due to the number of layers present, dressings can be bulky, which is a disadvantage, for example, for military personnel who may need to wear the dressing under body armor

Embodiment Construction

[0101] Figure 1 to Figure 3 A wound dressing 1 is shown in , comprising a base layer 2 , a top layer 3 and an island of adhesive 4 connecting the top layer 3 to the base layer 2 . Such as image 3 As shown, the wound dressing also includes a removable protective layer 5 and a skin contact layer 6 . The wound dressing 1 also comprises tabs 7 .

[0102] The base layer 2 comprises an upper surface 8 facing away from the wound and a lower surface 9 facing the wound. The base layer 2 comprises an orifice 10 located generally in the center of the base layer 2 .

[0103] The skin contact layer 6 comprises apertures 11 corresponding to the apertures 10 located in the base layer 2 . The skin contact layer 6 is made of a hydrogel adhesive, so that once the removable protective layer 5 is removed, the skin contact layer 6 can stick to the skin, the wound is located in the orifice 11, thereby forming a wound around the wound. Hermetic seal.

[0104] A removable protective layer 5 i...

Abstract

The present invention relates to wound dressings for use in cases of a patient suffering a penetrating chest trauma. The wound dressing comprises a base layer having a lower surface facing the wound and an upper surface facing away from the wound, and an aperture therethrough for locating over the wound, and a top layer extending over the aperture and at least a part of the upper surface. The baselayer is connected to the top layer such that the wound dressing can transition from an open configuration in which the aperture and an area external to the wound dressing are in fluid communicationvia at least one opening at a perimeter between the base layer and the top layer, to a closed configuration in which the top layer forms a seal over the aperture.

Description

technical field [0001] The present invention relates to wound dressings. More specifically, the present invention relates to wound dressings for use in the context of patients suffering from penetrating thoracic trauma. Background technique [0002] An open chest wound can refer to a wound in the chest wall that enters the lung cavity. A penetrating chest injury can be caused by an object, such as a bullet, shrapnel, or knife, that enters the chest of a human or animal body and penetrates the chest wall. Persons at risk of penetrating chest injuries include those handling weapons, such as law enforcement personnel, military personnel, and other occupational personnel at risk of sustaining open chest wounds. [0003] Penetrating chest injuries can result in a variety of conditions, including tension pneumothorax, open pneumothorax, and hemothorax. [0004] In a tension pneumothorax, air enters the pleural space of the patient's lungs and is not expelled by exhalation, ther...
