Patent number: 5156589Abstract: A cohesive bandage fabricated according to a method comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacryate ester and alkyphenyl polyethylene glycol ether to at least one fabric face is disclosed. In one embodiment, the coating is applied by an airless method microselectively in statistical distribution where the quantity of coating is controlled by pump pressure. Alternatively, an aqueous dispersion of polybutyl acrylate ester and carboxymethyl cellulose is microselectively and cohesively coated on both sides of the fabric by screen printing to produce a regular dot pattern on both faces of the fabric.Type: GrantFiled: October 24, 1991Date of Patent: October 20, 1992Assignee: Karl Otto Braun KGInventors: Gunter Langen, Harald Jung

Patent number: 4984570Abstract: The textile fabric is used as a wound dressing in much the same way as dressing gauze with improved characteristics compared with the latter and comprises a central web portion of man-made fibers having a high surface tension, and on either side thereof web portions formed from absorbent, cellulosic yarns. The central web portion is connected by looping to the outer web portions so that after folding, a nonstick wound dressing is obtained in which the hydrophobic man-made fibers functioning as the wound covering, come to rest on the wound, while the folded layers of cellulosic fibers behind it, act as an absorbent layer.Type: GrantFiled: September 14, 1989Date of Patent: January 15, 1991Assignee: Karl Otto Braun KGInventors: Gunter Langen, Harald Jung

Patent number: 4699133Abstract: The invention relates to a cohesive, self-adhesive, rigid or elastic bandage for fixing, compression and support dressings and permanent elastic compression and support dressings for medical purposes and a process for the manufacture thereof. The bandage comprises a web of warp and weft threads or warp threads in the form of a woven fabric having a porous structure and an amount of ultra fine particles of an adhesive, such as a rubber adhesive, distributed over and bonded to both the exposed surfaces of the warp and weft threads to provide adhesive particles bonded to the threads on both sides of the fabric. The adhesive particles are uniformly distributed over both bandage surfaces without the fiber groups adhering to one another or to the projecting fiber ends of the two surfaces, the particles being of a size distribution and amount sufficient to provide adhesion between overlying bandage surfaces without substantially reducing the porosity and elasticity of the fabric.Type: GrantFiled: May 23, 1985Date of Patent: October 13, 1987Assignee: Firma Karl Otto Braun KGInventors: Ewald Schafer, Harald Jung

Patent number: 4542739Abstract: An elastic, non-sticking wound textile formed of a highly elastic knitted fabric with a mesh-forming thread of a completely synthetic material facing the wound and highly absorbent yarns incorporated as the weft.Type: GrantFiled: January 18, 1983Date of Patent: September 24, 1985Assignee: Firma Karl Otto Braun KgInventors: Ewald Schafer, Harald Jung

Patent number: 4476697Abstract: The invention relates to a wound dressing which prevents or at least reduces sticking of the dressing to the surface of the wound due to contact with moisture from the wound and which without the use of over twisted threads has a controllable lifting action and an excellent secretion-absorbing action, whereby cutting of the dressing into strips does not lead to lateral fraying due to the cutting of the mesh as is the case with known knitted fabrics and in which the further use leads to complication. The present wound dressing comprises a knitted fabric formed with a basic stitch construction and with a plurality of inlay threads having a Z or S twist, the yarns of the inlay threads having the same thickness and twist, and being inserted as slightly or greatly displaced wefts.Type: GrantFiled: May 26, 1983Date of Patent: October 16, 1984Assignee: Karl Otto Braun KGInventors: Ewald Schafer, Harald Jung

Patent number: 4424808Abstract: The invention relates to a fabric which is highly longitudinally elastic in the warp direction and easily tearable in the weft direction, or highly longitudinally elastic in the weft direction and easily tearable in the warp direction, or highly longitudinally elastic and easily tearable in both the warp and weft directions, which is adhesively or self-adhesively coatable and has a crepe structure, whereby in bandage form it can be used as a fixing and compression bandage after distortions, luxations, fractures and similar injuries, as well as preventatively against injuries liable to occur when playing sports.Type: GrantFiled: April 30, 1980Date of Patent: January 10, 1984Assignee: Karl Otto Braun KGInventors: Ewald Schafer, Harald Jung

Patent number: 4236550Abstract: The invention relates to an elastic muslin bandage with in part elastic and non-elastic threads and with non-elastic weft threads which can be used elastically and as a fixing dressing having a high elastic behavior, permits an easy application to conical extremities and joints, is conductive to moisture and heat so that no moisture and heat chambers form, and in which slipping of the individual bandage layers is prevented, whereby the bandage is constructed in such a way that in the warp the web has textured polyfilic polyamide threads of thickness Td 70/13/2 or a lighter or heavier titre varying therefrom as the elastic element and threads of 17 tex staple fibre and/or bleached cotton of size Nm 60 or the like as the rigid element in a ratio 1:1, 1:2, 1:3, 2:1, 2:2, 2:3, 2:4 or the like, and in the case of a ratio of 1:1 in a number of 59 textured polyfilic polyamide fibres and 58 staple fibres based on the web width of 10 cm, and in the weft threads of 17 tex bleached cotton and/or staple fibre or a blendeType: GrantFiled: February 1, 1978Date of Patent: December 2, 1980Assignee: Karl Otto Braun KGInventors: Franz Braun, Ewald Schafer
