    Abstract: A medical article and methods of using same. The medical article can include a machine direction (MD) and a cross-machine direction (CMD); a support layer; and a viscoelastic layer. The viscoelastic layer can be coupled to the support layer, and the viscoelastic layer can be discontinuous in the MD and/or the CMD. The viscoelastic layer can recover at least 70% of its deformation after 48 hours at room temperature after being strained to 50% elongation, such that the medical article has a first tensile stiffness T1 at a first strain rate S1, and a second tensile stiffness T1 at a second strain rate S1. The ratio of S1/S2 can be at least 100, and the ratio of T1/T2 can be at least 1.5. The method can include wrapping the medical article around a body part; applying the first strain rate S1; and applying the second strain rate S2.

    Abstract: A compression device for applying compression to a body part of a user. The compression device has a sleeve with two lateral side regions and a central region in-between. The central region of the sleeve comprises a main material having elasticity in at least a transverse direction. A maximum elongation in the transverse direction is from 5% up to and including 30% under a load of 10 N per cm width and a difference quotient of tension in the transverse direction from 20% elongation to 25% elongation equal to or greater that 0.6 N per cm width per percent elongation. The device further includes a releasable closure system configured and arranged relative to the sleeve, such that, in use, upon closure of the closure system the sleeve is restrained and tightened about the body part of the user.

    Abstract: Disclosed is a monitoring system for determining the efficacy of at least one compression device for use in compression therapy. The monitoring system comprises at least one pressure sensor for measuring a pressure exerted onto a body part of a user by the compression device, at least one attitude sensor for acquiring at least one attitude information on at least one of a position, an orientation and a movement of the user, at least one measuring device having at least one evaluation unit. The measuring device is adapted to communicate with the pressure sensor and the attitude sensor. The evaluation unit is adapted to receive at least one attitude information acquired by the attitude sensor. The evaluation unit is adapted to automatically combine the pressure value and the attitude information in order to determine at least one key figure K indicating the efficacy of the compression device taking into account the attitude information.

    Abstract: A compression device for applying compression to a body part of a user. The compression device comprises a sleeve for substantially covering a portion of the body part of a user. The sleeve has an upper edge, a lower edge and an opening extending from its upper edge to its lower edge, said opening having two side edges. The first side edge is provided with one half of a zipper and the second side edge is provided with a complementary half of said zipper. The sleeve includes at least one expandable gusset provided with a releasable closure system extending along the length of said gusset, said gusset and releasable closure system being configured and arranged, such that when said releasable closure system is closed said gusset is prevented from expansion and when said releasable closure system is opened said gusset is allowed to expand.

    Abstract: Compression device (1) for application circumferentially around a patient's limb (10), comprising a) a first band portion (20a) and a second band portion (20b), both band portions (20) being arrangeable along at least a part of the circumference of the limb for creating radial pressure on the limb, b) a spine element (30), extending in axial direction (100) when the compression device is applied around the limb, and comprising a first and a second guide opening (40a, 40b) for guiding the first and the second band portions, respectively. The guide openings (40a, 40b) are arranged offset in axial direction with respect to each other such that, when the first band portion is arranged along at least a part of the circumference of the limb and guided through the first guide opening, and the second band portion is arranged along at least a part of the circumference of the limb, parallel to the first band portion, and guided through the second guide opening, the band portions overlap in an axial direction.
