A compression bandage in the form of a knit obtained with warp knit technology, formed of synthetic yarns and composed of two textile surfaces having the same or different textile structure, linked together by spacer threads, each surface has elastic yarns, and the spacer threads of the knit are multifilaments. The knit has longitudinal elongation measured as per standard EN 14704-1 of between 30 and 160% and threshold shear stress equal to or higher than 2800 Pa and/or conformability equal to or lower than 65 mm.

Optimized support bandage

A compression bandage in the form of a knit obtained by warp stitch technology on the basis of synthetic yarns and comprising two textile surfaces of respective textile structures that may be identical or different, the surfaces being interconnected by spacer yarns, each surface including elastic yarns, the bandage being characterized in that said knit presents:

Optimized compression bandage and kit using said bandage

The present invention relates to an adherent interface dressing intended for application directly to a wound. Said adherent interface dressing includes a non-adherent cohesive gel formed from a hydrophobic elastomeric matrix consisting of a styrene-(ethylene/butylene)-styrene or styrene-(ethylene/propylene)-styrene triblock elastomer optionally associated with a styrene-(ethylene/butylene) or styrene-(ethylene/propylene) diblock copolymer; said elastomer plasticized by means of a mineral oil, and containing dispersed therein a small quantity of hydrophilic particles of a hydrocolloid; and a flexible open-mesh fabric, said fabric including threads coated with the non-adherent cohesive gel such as to leave the meshes substantially unsealed, The fabric is a heat-set knit with weft yarns, said yarns being continuous multifilament yarns with non-elastic filaments, whereof the extensibility in the transverse direction measured in accordance with standard EN 13726-4 is between 0.01 and 0.5 N/cm.

Adhesive interface bandage

A compression bandage that is formed by the assembling of a self-adhesive nonwoven based on short conjugate fibers which have been crimped and of an elastic material, the effectiveness of which increases over time. The bandage can be used, alone or in a bilayer compression system, for the prevention or treatment of venous pathologies or lymphedema.

Elastic bandage having improved compression properties

A compression bandage formed by the assembling of a nonwoven based on short conjugate fibers which have been crimped and of a nonelastic material. The compression bandage can be used in a bilayer compression system, in particular for the prevention or treatment of venous pathologies.

Elastic bandage that can be used, in particular, for the treatment and prevention of vein diseases

A self-adhesive compression bandage, in particular for the treatment and prevention of pathologies of venous origin and lymphedema. This bandage is manufactured by the assembling of two self-adhesive nonwovens based on short conjugate fibers which have been crimped. The fibers are preferably made of polyester. The bandage can in addition comprise a supplementary layer.

Self-adhesive elastic bandage that can be used, in particular, for the treatment and prevention of diseases of the veins

The present invention relates to an item () having liquid (L) storage and/or discharge properties, in particular a bandage, comprising: &#x2014;a liquid-permeable proximal structure (), consisting of a material capable of inflating in the presence of liquid (L), &#x2014;a distal structure () capable of draining a liquid (L), &#x2014;a hydrophobic and non-absorbent spacer structure () extending between the distal () and proximal () structures, and being capable of locally limiting, when said material is not inflated, the exchange of liquid between the distal and proximal structures by maintaining a gap between said structures, and of authorizing a local expansion of the proximal structure in at least one zone (P) where said material is inflated in response to coming into contact with a liquid, said expansion causing the proximal and distal structure to move together locally and the transfer of said liquid from the zone of the proximal structure () having undergone expansion to the distal structure ().

Item intended to come into contact with a liquid, in particular a bandage

The subject matter of the present invention is a system for measuring interface pressure exerted on the skin, that is in particular of use in compression therapy, characterized in that it comprises: &#x2014;a supporting member bearing sensors, including at least two pressure sensors spaced out on the supporting member in order to make it possible to measure the pressure exerted at two predetermined positions; &#x2014;an electronic system connected to the sensors and capable of acquiring the values simultaneously measured by these sensors; and in that each pressure sensor comprises a transducer element, which is preferably substantially flat, said transducer element having a surface intended to come into contact with the skin in the operating position, either directly or by means of a layer of a material covering said surface of the transducer, the elastic modulus of compression of said transducer or of said intermediate layer, measured at the surface intended to come into contact with the skin, being between 30 and 500 kPa, preferably between 80 and 400 kPa and more preferably between 200 and 400 kPa. Use: compression therapy.

Interface pressure measurement system

The present invention relates to a support system particularly intended for treatment and prevention of diseases of venous origin, characterized in that it comprises a first support layer, which is composed of an elastic band attached across its entire surface to an absorbent layer, and a second support layer, which is a self-adhesive elastic band. This support system has a dynamic coefficient of elasticity of between 5 and 55 Newton/cm.
