  • Publication number: 20220226161
    Abstract: Medical dressings including stiffening systems fixedly attached to backing layers are described herein along with methods of using the medical dressings. The stiffening system is fixedly secured to the backing to limit flexing and stretching of the backing layer. Typically, the medical dressing and stiffening system is applied over a medical device that is secured to skin. The stiffening system covers some of the medical device and also extends beyond the medical device. The stiffening system stabilizes the medical device over the skin.

  • Patent number: 11278453
    Abstract: A compression system for applying compression to a body part of a user. The compression system has a sleeve for substantially covering a portion of the body part of a user. The sleeve has two lateral side edges. In the transverse direction from the first lateral side edge to the second lateral side edge the sleeve has a first lateral side region, a central region and a second lateral side region. At least the central region of the sleeve has a material with elasticity in the transverse direction and longitudinal direction of the sleeve. The compression system has a releasable closure system. Upon closure of the closure system the sleeve is restrained and tightened about the body part of the user.

  • Patent number: 10888463
    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.

  • Publication number: 20200375804
    Abstract: A compression bandage for a human calf having a) a first engagement zone on a first major surface, comprising mechanical engagement means, b) a second engagement zone on the first major surface, comprising mechanical engagement means, c) a soft section between the first and the second engagement zone, having a reduced modulus of elasticity in length direction, and d) a stiff section having an elevated modulus of elasticity in length direction, and having a length greater than the length of the soft section. The stiff section comprises a third engagement zone on the second major surface, comprising mechanical engagement means, for engagement with the first and with the second engagement zone. When wrapping the bandage around the calf, the third engagement zone can engage, in a subsequent turn, with the first engagement zone, and with the second engagement zone, so that the stiff section bridges the soft section.

  • Patent number: 10779994
    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.

  • Publication number: 20190336351
    Abstract: Compression bandage for use as the only bandage in a single-bandage system for compression therapy, comprising an elastic compression layer and an elastic comfort layer, of which at least 50% is permanently attached to the compression layer. The compression bandage has a full-stretch elongation (FSE) of between 25% and 60% beyond its unstretched length. Full-stretch elongation is defined as the elongation at which the second derivative (130) of a curve (110) showing tensioning force over longitudinal elongation has its global maximum (140).
