Methods, materials, articles, assemblies, systems, devices, kits and computer hardware/software for improving medical procedures, including, but not limited to, hemodialysis. Particular beneficial designs and uses of disinfecting patches, scab removal patches, hemostatic patches, healing patches and artificial scabs are included. For example, scab removal patches that avoid tenting, hemostatic patches with needle stabilizing elements, hemostatic patches applying pressure at a skin puncture site and a vessel puncture site, artificial scabs that release antimicrobial agents, etc.

A compression dressing includes an elastic bandage strip that is elongated, transparent and self-adhering, and has a first outer side and a second inner side, with a first unextended state and a second elastically extended state. A self-adhesive surface is provided on the first outer side of the elastic bandage strip. An absorbent pad at a terminal end of the elastic bandage strip is applied to a wound, and the remainder of the elastic bandage strip may be wrapped around the absorbent pad and a body part to hold the compression dressing in place and to exert a compressive force on the wound. An elastic bandage strip and/or the absorbent pad includes one or more of spaced apart blood migration markings, compression markings, and a skin adhesive. Methods for applying a compression dressing to a wound to both observe the status and treat the wound are also disclosed.

The present invention provides a hemostatic composite sponge comprising oxidized cellulose and an essentially gelatin-free bioadhesive material stably associated with said sponge and present in an organized pattern on said sponge.

A pressure bandage including an elastic sheet having a first coefficient of elasticity and an adhesive side. The pressure bandage may also include a resilient pad having a second coefficient of elasticity and affixed to the adhesive side of the elastic sheet. The elastic sheet has a first predetermined shape that is configured to be applied to a corresponding anatomical location on the body of a patient. The first coefficient of elasticity and the second coefficient of elasticity are related such that, when the elastic sheet is stretched and adhered to the body of the patient, the resilient pad applies a predetermined amount of pressure to the body of the patient.

Provided are a fibrous sheet having a stress relaxation rate defined by the following formula of less than or equal to 85%:

stress relaxation rate [%]=(stress S.sub.5 at extension after five minutes/stress S.sub.0 at initial extension)?100

when a stress at extension immediately after extension in an in-plane first direction at 50% elongation is defined as a stress S.sub.0 (N/50 mm) at initial extension, and a stress at extension at a time of extending in the first direction at 50% elongation for five minutes is defined as a stress S.sub.5 (N/50 mm) at extension after five minutes, and a bandage including the fibrous sheet.

The present invention provides a hemostatic composite sponge comprising oxidized cellulose and an essentially gelatin-free bioadhesive material stably associated with said sponge and present in an organized pattern on said sponge.

Embodiments herein provide hemostatic compositions comprising a plurality of liquid-expandable articles arranged on a backing material. In general, embodiments include methods for treating hemorrhagic injuries. More specifically, there is provided a method to effect rapid hemostatic response and control hemorrhage by introducing a hemostatic composition into a bleeding wound cavity. An embodiment also provides a method of preparing or manufacturing such a hemostatic composition.

The invention relates to a haemostatic bracelet (1) comprising: a clamp comprising two branches (11, 12) and a first strut (13), each branch (11, 12) being connected by one of its ends to the other branch by means of the first strut (13), a compression element (24) placed, when the bracelet is ready for use, inside the space defined by the branches (11, 12) and the first strut (13) of the clamp or inside a projection of this space, the compression element (24) protruding in the direction of the opening between the ends of the branches (11, 12) of the clamp opposite to the first strut (13), actuation elements (30, 40) fixed to the branches (11, 12) of the clamp so that the ends of the branches (11, 12) of the clamp opposite to the first strut (13) can be spread by moving the ends of the actuation elements towards each other.

The present invention provides a hemostatic composite sponge comprising a porous matrix of a biomaterial and a bioadhesive material stably associated with said sponge and present in an organized pattern on said sponge.

A unique multi-functional emergency bandage stops bleeding by: (1) optimizing mechanical properties and preventing ischemia and/or necrosis while applying enough pressure to help stop bleeding, and (2) incorporating inorganic anti-bleeding nano-structures (embedded within a gauze and/or microbial cellulose) with almost infinite life-time. Additionally, pathogen passage through the bandage is prohibited (via an intermediate filter layer). Together with the overall anti-microbial character of the bandage, the unique multi-functional bandage offers all these vital features within a single design. The unique bandage can be applied by using a single hand and bandaging direction can be changed using a unique binding apparatus. Visual aids, such as printed rectangles, on the final fabric provides the user with an indication of how to control the amount of stretch, as vertical rectangles would turn into horizontal rectangles when stretched too much, whereas rectangles turn to squares around the optimum region of the stress-strain curve.
