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.

Adjustable covers, systems, and methods are presented that include an adjustable cover that may be adjusted to an appropriate size by hand without requiring cutting tools and without substantial leaks. In one instance, the adjustable covering includes a drape member with a plurality of non-leaking tear paths. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The adjustable covering may further include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path. The grains of the drape member, a backing layer, and support layer may also be in the same direction. Other adjustable covers, systems, and methods are presented.

A bandage for use at an aggressive bleeding site of a patient is disclosed. The bandage includes a stretchable wrap, an auxiliary strap, a primary absorbent body, and at plural secondary absorbent bodies. The primary absorbent body is located on the inner surface of the wrap. The wrap is arranged to be wrapped about and tightly encircle a portion of the body of a patient at which the bleeding site is located to cause the primary absorbent body to apply pressure thereto. The auxiliary strap is secured to the wrap and is normally held in stowed position on the wrap, but arranged to be moved to an extended position whereupon the secondary absorbent bodies overlies said primary absorbent body and apply pressure thereto and to the underlying aggressive bleeding site.

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.

An apparatus for keeping dry a portion of a person's skin, including a belt portion having an outer side and an inner side, configured for placement of the inner side against an abdominal area of a person's body to prevent water from passing between the inner side and the abdominal area, and also including a body portion configured to cover at least a portion of the abdominal area. The body portion may include a body top end forming a first opening sized to receive a portion of the abdominal area, and include a body bottom end having at least one second opening sized to receive a portion of the person's body, and a body middle connecting the body top end and the body bottom end. Also, a method for keeping dry a target portion of a person's skin using an apparatus having a belt portion and a body portion.

In accordance with an aspect of the present invention, there is provided a wound dressing with elastic properties for use with a human or an animal. The wound dressing includes a plurality of individual segments, each segment connected to at least one other segment by an elastic connector, and each segment having at least two perforated layers, with at least one layer having a plurality of protrusions. The wound dressing further includes a plurality of spacing elements, with each spacing element disposed between adjacent segments and retained by either the adjacent segments or the elastic connector.

Systems, assemblies, and methods for providing negative-pressure therapy to a tissue site are described. The system can include an absorbent and a sealing layer configured to cover the absorbent. The system can also include a blister fluidly coupled to the absorbent. The blister may have a collapsed position and an expanded position. A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.

Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

A device for treatment of an umbilical hernia includes a first section of flexible, elastic material including an adhesive layer on rearward side thereof. The first section includes an opening therein dimensioned to encompass the umbilical. The device further includes a plurality of extending sections of flexible, elastic material attached to and extending from the first section. Each of the extending sections includes an adhesive layer on a rearward side thereof. The first section is less elastic than each of the plurality of extending sections.

The invention relates to a primary dressing for moist wound healing with a reduced risk of inflammation. The elastic primary dressing according to the invention for moist wound healing is in the form of a lattice or a netting made of elongated elastic bodies, said lattice or netting containing non-resorbable elongated bodies that consist of silicone and optionally at least one additive selected from active pharmacological ingredients, collagens, hydrocolloids, and/or dyes. The lattice or netting preferably contains resorbable elongated bodies in addition to the non-resorbable elongated bodies, said resorbable elongated bodies containing at least one resorbable and bioactive organic compound, in particular selected from collagens and hydrocolloids. The invention also relates to a wound dressing that the primary dressing according to the invention contains in combination with a secondary dressing. The invention also relates to methods for producing primary dressings according to the invention.
