Device for the recovery of cell-free serum from whole blood, comprising a blood bag for the reception and the coagulation of the whole blood into a solid fraction and into a fluid containing a serum, wherein the blood bag has an outlet and a barrier in the area of the outlet which is suitable for retaining at least a major portion of the solid fraction and for the passage of said fluid, a filter module which is fluidically connected to the blood bag via the outlet, comprising an interior in which a semi-permeable membrane is arranged which subdivides the interior into a retentate space and a permeate space and allows the separation of the fluid into a serum as a permeate and into a retentate in which possible particulate components contained in the fluid remain, wherein the filter module has an inlet device for introducing the fluid into the retentate space and a permeate outlet for discharging the serum from the permeate space, and at least one receiving container for serum, comprising an inlet opening which is connected to the permeate outlet of the filter module via a connecting line.

Method for the recovery of cell-free serum from whole blood, wherein the method can be carried out by means of the described device.

A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.

The invention discloses a medical bandage, and relates to the technical field of medical supplies. One specific implementation mode of the medical bandage comprises: a bandage body and an adhesive layer provided on the surface of the bandage body; the bandage body including: a non-woven fabric base and a plurality of elastic reinforcing filaments that are sewn into the non-woven fabric base and extend in the warp direction of the non-woven fabric base; wherein the non-woven fabric base is provided with a plurality of cutting positions that are arranged at equal intervals in the warp direction; each cutting position is provided with at least one linear cutting opening that extends in the weft direction of the non-woven fabric base; and each elastic reinforcing filament punctures the non-woven fabric base up and down to form continuous coils surrounding the non-woven fabric base. The implementation mode enables easily tearing apart the bandage with bare hands in the weft direction, and has a certain strength and a certain elasticity in the warp direction.

A water resistant light compression and/or retention bandage for retaining an orthopedic splint, padding or medical device against a body part, includes a knitted fabric formed of synthetic yarns having a moisture vapor transmission rate from an inner face of the bandage to an outer face of the bandage of at least 500 g/m.sup.2 per 24 hours.

According to the invention, a wound dressing may be further developed, whereby a wound dressing made from a planar structure with a first main direction of extension and at least one further main direction of extension, whereby the textile planar structure, at least along the main directions of extension comprises extensibility properties which differ by less than 80%, preferably less than 50%.

Antimicrobial dressings for prevention and mitigation of biofilm and bacterial infection by an applied electric current are provided. Methods of making the dressings and methods of applying an electric current to promote the wound healing process are also disclosed.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

A knit hemostatic bandage provided herein can include a continuous rayon fiber and a continuous glass fiber. The knit hemostatic bandage can have a gauge of between 10 and 30 stitches per inch. The knit hemostatic bandage can have a Young's modulus of elasticity of less than 50 MPa.

This invention relates to a hybrid fabric comprising at least one structural fiber having a first melting temperature range and at least one thermo-formable fiber of having a second melting temperature range which is lower than the first melting temperature range to such an extent that the structural fiber does not melt in the second melting temperature range of the thermo-formable fiber. The hybrid fabric comprises (1) a first network comprising the structural fibers, (2) a second network comprising the thermo-formable fibers, the thermo-formable fibers comprising non-relaxed fibers made of a thermoplastic material, and (3) a plurality of openings between the fibers of the first and second network. The structural and thermo-formable fibers of respectively the first and second network interpenetrate one another and are connected to each other over at least part of the first and second network at a plurality of knot positions in the fabric where the structural and thermo-formable fibers are interwoven.

Disclosed herein are antimicrobial elastic support bandages including a plurality of warp threads extending along at least a portion of the length thereof and including non-antimicrobial warp regions and antimicrobial warp regions arranged in an alternating fashion across the width thereof, wherein (a) a non-antimicrobial warp region comprises an elastic material that is stretchable in the direction of the length, (b) an antimicrobial warp region comprises (i) a flexible fiber coupled to an antimicrobial metal, and (ii) an elastic material that is stretchable in the direction of the length, wherein the flexible fiber is coupled to the elastic material, and (c) at least a portion of the warp threads are separated by about 3 microns to about 20 microns; and further including a plurality of weft threads extending across at least a portion of the width and comprising a biocompatible material, wherein at least some of the weft threads are separated by about 3 microns to about 20 microns, wherein at least a portion of the warp threads are interwoven with at least a portion of the weft threads.
