Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.

A dressing for treating tissue with negative pressure is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

Devices and methods for encapsulating a portion of a wound dressing with a coating are disclosed. In some embodiments, a method can comprise positioning a substantially flexible wound contact layer of the wound dressing on a perforated plate. The wound contact layer can include a first side supporting a plurality of electronic components protruding from a surface of the first side and a second side opposite the first side. The second side can be substantially smooth. The method can further comprise applying a vacuum to the wound contact layer through perforations in the perforated plate to hold the wound contact layer against the perforated plate and coating the wound contact layer with a coating.

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

A wound packing material is provided, suitable for use in negative pressure wound therapy, including a body of a porous material, the body including frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. Methods of manufacturing the wound packing material, and methods of its use are also provided.

Dressings, systems and methods of treating a tissue site are described. A method of manufacturing the dressing can include providing a dressing material. The dressing material can have a surface configured to contact the tissue site. The dressing material can also have a plurality of pores. The method can further include applying a compressive force to the dressing material at an angle to the surface, the compressive force causing permanent deformation of the plurality of pores. Causing permanent deformation of the plurality of pores can comprise forming a plurality of compressed pores. Forming a plurality of compressed pores can include compressing the plurality of pores from a generally circular shape to a generally ovular shape.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

A method of making a bespoke knitted compression garment. The method comprises providing a representation of a body part on which the compression garment is to be worn (S102), the representation comprising a plurality of datapoints. A desired pressure configuration to be applied by the compression garment on the body part is determined (S104). Representation courses around the representation are defined (S106). Sets of datapoints for each representation course are selected (S107). A curve for each set of datapoints and a circumference value of each curve is calculated (S108, S109). A pressure to be applied by each course is determined (S111) and a material for knitting, and a number of needles for each representation course, is determined based on the course pressure of the associated material course, a strain characteristic of the material, and the circumference value of the associated curve (S112). A garment is knitted according to the number of needles and the material (S113, S114).

Methods and apparatuses are disclosed relating to the creation and use of bespoke wound fillers and other wound treatment apparatuses. Some embodiments provide for the creation of bespoke wound fillers based on characteristics of a wound. Certain embodiments also include the use of bespoke wound fillers in combination with negative pressure to treat a wound.
