MULTILAYER STERILISING ENVELOPE Russian patent published in 2010 - IPC A61L2/26 A61B9/00 

FIELD: medicine.

SUBSTANCE: invention refers to disinfection and sterilisation of products, e.g. of medical devices. A multilayer sterilising system contains three sheets. Property sets of the first and second sheets contain one or more properties specified from the group including strength, barrier properties, abrasive resistance, cutting resistance, sliding resistance, hydrophilic nature, capillarity, absorbency, marking ability, printing ability, sterility indication, fastener reception and adhesive attachment. The third property set contains at least one complementary property found neither in the first property set, nor in the second one, or has a property of essentially higher level than those of the first or second property sets. The first and second sheets consist of a multilayer material, namely the first propylene layer of spinning blow and the second propylene layer of spinning. The third sheet contains nylon or polyester fibres. The sheets are connected by the fasteners.

EFFECT: use of the multilayer sterilising envelope allows reducing necessity of resterilisation due to improved properties of the sterilising system and packing a product.
