This application relates generally to wound bandages and garments, and more specifically to a wound care bandage or garment that covers specific portions of a patient's body such as an arm, a leg, a foot, or an abdominal region.
The dressing, changing, and care of wounds may require the placement and securing of absorbent bandages covering the wound. This is true whether the wound or wounds are from a surgery, a sharp blade, a projectile, a burn, a blunt impact, an illness, infection, stitches, transplant, or other reason for covering the surface of a patient's body with a bandage. Currently, many surgeries are performed with lasers and/or robotics which require several small punctures instead of traditional surgery using larger incisions. These smaller punctures are usually farther apart than what can be accommodated by a single traditional bandage, and therefore require more than one traditional bandage which creates an added inconvenience. Known bandages require time, skill and precision for proper application, which if not properly applied, may result in slippage or leaking of excess fluids, or may even result in uncovering the wound or wounds when the patient moves. Known bandages can also result in discomfort when adhesive is both applied to and then removed from the patient's skin.
A bandage used for improved wound care is claimed, including a non-adherent, deformable inner layer, a leak-proof outer layer that is substantially coextensive with the inner layer, and an absorbent middle layer contacting both the inner and outer layers. An adhesive strip and two or more adhesive tabs along one side serve to attach and adjust the fit of the bandage to securely hold the absorbent layer in contact with the wound and allow substantial freedom of motion without slipping. The adhesive strip and tabs secure the bandage in place without any adhesive touching the skin, thereby providing convenience and causing no pain or discomfort upon removal or replacement of the bandage. Elastic cuffs on the top and bottom sides prevent excess fluids from leaking and help hold it in place. One embodiment includes elastic around leg holes.
The bandage or garment may be designed to wrap around a part of a body having a wound. The bandage may use a non-stick netting material layer to improve patient comfort, and elastic cuffs to improve fit and leakage. The fitted garment may appear similar to a sleeve having a tube shape, and may cover large areas to reduce the probability of the bandage slipping off of the wound area.
In one embodiment, the bandage comprises: an inner layer, a middle layer, an outer layer, a top edge, a bottom edge, a right edge and a left edge, the inner layer being deformable and non-adherent, the outer layer being substantially impermeable to liquid, and being substantially coextensive with the inner layer, the middle layer being disposed between and contacting both the inner and outer layers, the middle layer being absorbent; at least one attachment strip connected to the inner and/or outer layers along substantially the entire length of the right edge and/or the left edge; at least one adjustable tab connected to the right edge and/or the left edge; and at least one cuff connected to the outer layer and disposed at a selected distance from the top edge and/or the bottom edge.
In some embodiments, the inner layer includes a woven material. In other embodiments, the inner layer includes a netting material. In other embodiments, the inner layer is attached along at least one edge to the outer layer by a netting edge seal. In other embodiments, the outer layer includes an elastic leak-proof material. In other embodiments, the middle layer is connected to the inner layer and/or the outer layer. In other embodiments, the middle layer adheres to the inner layer and/or the outer layer.
In some embodiments, the attachment strip includes an adhesive and/or a hook and loop system. In other embodiments, the adjustable tab includes an adhesive and/or a hook and loop system. In other embodiments, at least one cuff includes a band of elastic material having a selected width. In other embodiments, the inner layer is a flat rectangular sheet having a selected width and a selected length. In still other embodiments, the inner layer includes two substantially circular elastic holes having a diameter and location disposed to enable insertion of a human leg into each hole of the two substantially circular elastic holes. In other embodiments, the right edge and/or the left edge, includes a plurality of attachment points on the outer side for connection with the at least one attachment strip and/or the at least one tab.
In one embodiment, the bandage comprises: an inner layer, a middle layer, an outer layer, a top edge, a bottom edge, a right edge and a left edge, the inner layer being deformable and non-adherent, the outer layer being substantially impermeable to liquid, and being substantially coextensive with the inner layer, the middle layer being disposed between and contacting both the inner and outer layers, the middle layer being absorbent; an adhesive attached to least one of the inner layer and the outer layer, along substantially the entire length of the right edge and/or the left edge; at least one adhesive tab attached the inner layer and/or the outer layer, along substantially the entire length of the right edge and/or the left edge; and two elastic cuffs connected to the outer layer and disposed at a selected distance from the top edge and/or at the bottom edge. In some embodiments, the inner layer includes a woven material, a non stick material, and/or a netting material.
In some embodiments, the deformable material is attached along at least one edge to the outer side by a netting edge seal. In other embodiments, the middle layer comprises an elastic leak-proof material. In other embodiments, the middle layer is connected to at least one of the inner layer and the outer layer. In some embodiments, the middle layer adheres to the inner layer and/or the outer layer. In other embodiments, the inner side includes a flat rectangular sheet having a selected width and a selected length.
The term “leak-proof” as used in the description may include material that substantially resists the movement of fluids such as water. Prepositions, such as “on”, “side”, “higher”, “lower”, “over” and “under”, “top” and “bottom”, “inner” and “outer” are defined with respect to the top of the bandage as laid out on a table, regardless of the orientation in use.
The detailed description refers to the accompanying drawings that show, by way of illustration, specific aspects and embodiments in which the present disclosed embodiments may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice aspects of the present invention. Other embodiments may be utilized, and changes may be made without departing from the scope of the disclosed embodiments. The various embodiments can be combined with one or more other embodiments to form new embodiments. The detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, with the full scope of equivalents to which they may be entitled.
