Abstract
The invention relates to a surgical drape (1) comprising a main sheet (10), characterized in that it comprises a drape attachment (20) composed of: a separable film (22) having at least one internal layer (22a) and one external layer (22b), the internal layer (22a) having less mechanical resistance than the external layer (22b), and a layer of adhesive (24), fixed to the internal layer (22a) of the separable film (22), the drape attachment being fixed to the main sheet (10) by means of the layer of adhesive (24).
Claims18
An operating drape comprising:
- a main sheet;
- and
- a drape attachment, wherein the drape attachment comprises:
- a separable multilayer film having at least one internal layer and an external layer, the at least one internal layer having lower mechanical resistance than that of the external layer such that the at least one internal layer breaks or tears before the external layer during traction force exerted on the separable multilayer film, wherein internal cohesion of the at least one internal layer is less than internal cohesion of the external layer, the material of the at least one internal layer being distinct from the material of the external layer, and
- a layer of adhesive fixed to the at least one internal layer of the separable multilayer film, the drape attachment being fixable to the main sheet by the layer of adhesive,
- wherein the layer of adhesive has a greater mechanical resistance to peeling than that of the at least one internal layer of the separable multilayer film, such that when traction force is applied to the drape attachment, the at least one internal layer of the separable multilayer film breaks or tears before the layer of adhesive unsticks from the main sheet or the drape attachment.
3 more elements
An attachment for an operating drape, the attachment comprising:
- a separable multilayer film extending longitudinally in a direction, having at least one internal layer and one external layer, the at least one internal layer having less mechanical resistance than that of the external layer such that the at least one internal layer breaks or tears before the external layer during traction force exerted on the separable multilayer film, wherein internal cohesion of the at least one internal layer is less than internal cohesion of the external layer the material of the at least one internal layer being distinct from the material of the external layer, and
- a layer of adhesive extending longitudinally in said direction, fixed to the at least one internal layer of the separable multilayer film,
- wherein the layer of adhesive has a greater mechanical resistance to peeling than that of the at least one internal layer of the separable multilayer film, such that when traction force is applied to the attachment, the at least one internal layer of the separable multilayer film breaks or tears before the layer of adhesive unsticks from the attachment.
