The present teachings generally relate to a bandage configured to bind a wound or to protect an injured appendage of the body. More specifically, the present teachings generally relate to a dispenser for a bandage manufactured on a continuous roll, allowing a user to cut a desired length of bandage based on a specific wound size. The bandage roll may include a self-adhesive that removably adheres to a portion of the bandage yet can be overlapped to form a sufficient bond to protect a wounded appendage.
Conventional self-adhesive bandages are typically packaged individually in a wrapper to avoid contamination of the bandage prior to application. The individual bandages are pre-cut to specific lengths, requiring a user to search for an appropriately sized bandage for a wound. Continuous rolls for self-adhesive bandages have been proposed to improve the convenience and customization of the bandages for users addressing wounds. However, continuous rolls often require special medical cutting tools (i.e., medical scissors) to cut a desired length of the bandage. Furthermore, continuous rolls are often difficult to cut, difficult to unroll manually, or both.
Additionally, a release paper adhered to the self-adhesive side of the bandage is often required so that the bandage can be rolled on itself without being contaminated. Further, without a release paper the bandage will adhere to itself, resulting in damage that renders the bandage unusable. Thus, a user is required to unroll a desired portion of the bandage, cut a desired length, and remove the release paper prior to application. Typically, a user will have difficulty removing the release paper without damaging the bandage piece or accidently adhering the bandage piece to itself.
Examples of such rolls may be found in the following potentially related documents: Published U.S. Patent Application 2007/0179466; U.S. Pat. Nos. 5,843,011; 6,362,388; 6,756,519; 8,851,284; and PCT Publication No. WO 97/17045, all of which are incorporated by reference herein in their entirety for all purposes.

The pivot may be a notch, cutout, or both. The pivot may be located near a terminal edge of the body portion, the moveable portion, or both. The pivot may be a connection point between the body portion and the moveable portion. The pivot may allow for the moveable portion to articulate between an open position (i.e., a direction moving away from the body portion), a closed position (i.e., a position where the body portion and the moveable portion are in contact), one or more positions between the open position and the closed position, or a combination thereof. The pivot may allow the moveable portion to articulate approximately 30 degrees or more relative to the body portion, about 60 degrees or more relative to the body portion, or about 90 degrees or more relative to the body portion. The pivot may allow the moveable portion to articulate about 180 degrees or less relative to the body portion, about 150 degrees or less relative to the body portion, or about 120 degrees or less relative to the body portion. The pivot may allow the moveable portion to articulate so that a cutter of the moveable portion may contact a portion of a continuous bandage roll.
The cutter may function to cut a desired length of the bandage roll. The cutter may be positioned anywhere on the body portion, the moveable portion, or both. The cutter may be any cutting member that cuts a portion of the bandage without damaging the cut portion of the bandage roll, the remaining bandage roll, or both. The cutter may be mounted on the moveable portion of the dispenser to articulate in an opening direction (i.e., away from the body portion), a cutting direction (i.e., towards the body portion and the bandage roll), or a combination thereof. The cutter may be fixedly mounted to the moveable portion, the body portion, or both. The cutter may be moveable mounted to the moveable portion, the body portion, or both. For example, the cutter may be retractable in the moveable portion so that the cutter may be extended for cutting the bandage roll and then retracted after use to prevented accidental injury or damage. The cutter may be any size and shape to sufficiently cut through any bandage roll varying in size and shape. The cutter may include one or more lubricants to ensure that the cutter does not adhere to an adhesive layer of the bandage roll during cutting. The cutter may be received by one or more recesses of the dispenser in a closed position to prevent accidental injury. The cutter may be a blade, tooth, edge, any sharp portion of the dispenser, or a combination thereof. The cutter may be structurally rigid. The cutter may be removably attached to the dispenser to allow for replacement once the cutter has dulled. The cutter may be positionable along the dispenser to accommodate different bandage rolls. The cutter may be sufficiently sharp to cut through a bandage roll without bending or compressing the bandage roll. A plurality of cutters may be located on the dispenser. For example, a first blade may be located on the moveable portion and oppose a second blade located on the body portion so that, during cutting, the first blade and the second blade sandwich the bandage. Alternatively, a first and second blade may be located adjacent to one another on the moveable portion.
The cutter may be protected by a shield. The shield may function to cover the cutter and prevent unwanted contact between the cutter and a user. The shield may function to shield the cutter from a user, debris, moisture, or a combination thereof. The shield may be mounted near the cutter anywhere along the dispenser.

The absorbent layer may be any sterile material that protects the one or more wounds from moisture, bacteria, or both. The absorbent layer may be a fabric, polymer, or both. The fabric may be woven or nonwoven. The fabric may cotton, wool, other fibrous material, or a combination thereof. The absorbent layer may be a gauze, plastic film, gel, foam, hydrocolloid, alginate, hydrogel, polysaccharide paste, or a combination thereof. The absorbent layer may include one or more coatings on a surface layer to prevent the absorbent layer from sticking to the one or more wounds. The one or more coatings may be a polymer coating. The absorbent layer may be a plurality of layers. For example, the absorbent layer may include a plurality of plies. The absorbent layer may be compressible. The absorbent layer may be nonabrasive. The absorbent layer may include one or more padding materials. The absorbent layer may be moisture wicking, moisture resistant, or both. A surface of the absorbent layer may be flush with the surface of the support layer having the adhesive layer. For example, the support layer may include a recessed portion that extends longitudinally along the support layer that receives the absorbent layer so that the surface of the support layer and the surface of the absorbent layer are coplanar.
The absorbent layer may include one or more reagents dispersed on a surface of the absorbent layer. The one or more reagents may be a medicament, antibiotic, anti-inflammatory, coagulator, disinfectant, scabicide, antifungal, or a combination thereof. The one or more reagents may be a liquid, a sold, a gel, or a combination thereof. The one or more reagents may include a release coating to promote long-term release of the one or more reagents.
The absorbent layer may be any size and shape to adhere to the support layer. The absorbent layer may have a width less than a width of the support layer so that the absorbent layer is fully supported and contained on a surface of the support layer. The absorbent layer may be sufficiently adhered to the support layer to prevent separation between the absorbent layer and the support layer. The absorbent layer may be positioned substantially along a longitudinal axis of the support layer. The absorbent layer may be positioned off centered from the longitudinal axis of the support layer. The absorbent layer may have a width less than the support layer. For example, the width of the absorbent layer may be about 100% or less, about 75% or less, or about 50% or less than a width of the support layer. The width of the absorbent layer may be about 10% or more, about 25% or more, or about 45% or more than a width of the support layer. The absorbent layer may vary in thickness. The absorbent layer may have a thickness of about 0.5 mm or more, about 1 mm or more, or about 5 mm or more. The absorbent layer may have a thickness of about 10 mm or less, about 8 mm or less, or about 6 mm or less.
The absorbent layer, the support layer, or both may be protected by a release material layer. The release material layer may function to cover the absorbent layer, the support layer, or both prior to application of the bandage roll to one or more wounds. The release material layer may be configured to release from the adhesive of the support layer without damaging the bandage roll. The release material layer may be removed prior to cutting the bandage, after cutting the bandage, or both. The release material layer may be any material, such as paper, plastic, or both. The release material layer may include one or more coating to decrease adherence between the release material layer and the support layer, the absorbent layer, or both. The release material layer may include one or more perforation, one or more lines, or both to aid in cutting the bandage roll to a desired length. The release material layer may allow a user to extend a portion of the bandage roll beneath the cutter to a desired length and maintain a force on the bandage roll to keep the bandage taught during cutting.
Turning now to the figures,
Furthermore, the body portion 22 of the bandage dispenser assembly 10 may include a support surface 76 adapted to maintain a position of the bandage dispenser assembly 10 during, before, or after use. That is, the support surface 76 may rest on a table surface or other surface during, before, or after operation to keep the bandage dispenser assembly 10 upright. Advantageously, the support surface 76 may be integrally (i.e., monolithically) formed with the body portion 22 to avoid additional components, thereby simplifying manufacturing and use of the bandage dispenser assembly 10. For example, the body portion 22 may be substantially arcuate along substantially all of an exterior surface of the body portion 22 transversely to an axis of the bandage 12 therein. However, the support surface 76 may be a planar region along the arcuate surface of the body portion 22 to prevent unwanted tipping of the bandage dispenser assembly 10 when resting on a surface such as a tabletop.
It should also be noted that the moveable portion 24, the body portion 22, or both may be any desired contour, shape, design, or a combination thereof. For example, any portion of the bandage dispenser assembly 10 may include a slot 40, an abrasive surface 44, additional features, or a combination thereof. The moveable portion 24, the body portion 22, or both may include an arcuate or contoured surface as illustrated or may be substantially planar in one or more locations. For example, the bandage dispenser assembly 10 may include one or more planar portions, one or more undulating portions, one or more linear segments, one or more arcuate segments, one or more fillets, one or more steps, one or more notches, one or more grooves, or a combination thereof.
As illustrated, the moveable portion 24 and the body portion may be separate, connected pieces of the dispenser and thus be manufactured separately, together, or both. To connect the moveable portion 24 to the body portion, the moveable portion 24 may include one or more ears 62 formed integrally with the moveable portion 24. Each ear 62 may include a projection 64 extending substantially transverse to an interior surface of the ear to mate with a channel of the body portion (see
The moveable portion 24 may also include a cavity 78 therein adapted to receive at least a portion of a bandage when connected to the body portion of the dispenser. It is envisioned that the cavity may be formed between or otherwise surrounded by a lip 74B of the moveable portion 24.
Advantageously, the lip 74B of moveable portion 24 may mate with a lip 74 of the body portion (see
Similarly, the lips 74 may include a seal so that compression of the moveable portion 24 and the body portion compresses the seal to create a substantially or entirely airtight cavity 78 within the dispenser. For example, the seal may be a thermosetting or thermoplastic material. The seal may be a rubber. The rubber may be natural or synthetic. The seal may be expandable, foamable, or both. The seal may be integrally formed with the moveable portion 24, the body portion, or both. The seal may be a secondary material secured to the lips 74. As such, it is envisioned that the seal may be a portion of or secured to a terminal surface of the lips 74 that mates with a complimentary lip 74.
Advantageously, it may be gleaned from the present teachings that the dispenser may provide a sterile storage means for the bandage roll located within the dispenser. That is, even throughout operation of the dispenser for cutting various portions of the bandage roll, the dispenser may beneficially seal any remaining portion of the bandage roll (e.g., an uncut portion) within the cavity 78, thereby preventing debris or contaminants from reaching the bandage roll. As a result, a user may be able to continuously use the bandage roll such that the bandage roll remains entirely sterile.
As mentioned above, the bandage roll (not shown) may be unreeled and cut to a desired portion by moving the moveable member 24 relative to the body portion. To do so, a user may unreel a desired length of the bandage roll such that the unreeled length extends beneath a cutter 28 of the moveable portion 24. The cutter 28 may then be pressed down onto the bandage to cut the desired length of the bandage. As shown, the cutter 28 may have a taper along its edge spanning along a width of the moveable portion 24. As a result, the bandage may gradually contact the entirety of the cutter 28 before fully cutting off a portion of the bandage.
Due to the tapering of the blade 28, a nub 30 located along the moveable portion 24 may contact the bandage and ensure that the uncut bandage not being removed from the dispenser is clamped down and sealed within the cavity 78. That is, the nub 30 may compress and seal the bandage roll in conjunction with the lips 74 to ensure a sterilized environment for the bandage roll. As such, the bandage roll remains sterile throughout use, even after cutting a portion of the bandage roll. Moreover, the nub 30 facilitates compression of the bandage to ensure that a user need not contact the uncut portion of the bandage, thereby even further preventing potential contamination.
Additionally, the moveable portion 24 may include one or more abrasive surfaces 44 to provide a user a contact region when using the dispenser. The abrasive surfaces 44 may be integrally (i.e., monolithically) formed with the moveable portion 24. The abrasive surfaces 44 may be secured (e.g., adhered, fastened, or both) to the moveable portion 24 as a secondary component. For example, the moveable portion 24 may be a plastic material while the abrasive surface 44 may be a rubber material.
Furthermore, a shield 38 my extend from the moveable portion 24 adjacent to the cutter 28 to prevent a user from accidentally contacting the cutter 28 during operation. The shield 38 may extend substantially parallel to an extension direction of the cutter 28 relative to the moveable portion 24. Moreover, the shield 38 may extend a greater distance from the moveable portion 24 such that an entirety of the cutter 28 is obstructed by the shield 28 to prevent unwanted or accidental contact with the cutter 28.
The body portion 22 may define a cavity 78 adapted to hold a bandage roll 12. An entirety of the cavity 78 may be formed when the moveable portion 24 mates with the body portion 22, thereby fully encapsulating the bandage roll 12 in a sterile environment. That is, lips 74A of the body portion 22 may mate with the lips 74B of the moveable portion 24 to form an entirely sealed cavity 78 therein. For example, as discussed above, the lips 74A of the body portion 22 and the lips 74B of the moveable portion 24 may both extend along an entirety of the perimeter of the complimentary cavity 78 portions. As a result, the lips 74 may contact one another to ensure no gap is present between the moveable portion 24 and the body portion 22 when the dispenser is fully closed. Thus, the bandage roll 22 may remain entirely sterile during, before, and after use. Advantageously, the unused portion of the bandage roll 22 may remain intact and sterile even after one or more cut portions are removed.
Moreover, as mentioned above, the moveable portion 24 and the body portion 22 may connect to each other in a moveable manner at a pivot 26. A barrel 56 having a channel 58 at least partially extending therethrough may receive the projections 64 located along ears 62 of the moveable portion 24. The barrel 56 may also include a depressed region 60 located on one or more end surfaces of the barrel 56. The depressed regions 60 may facilitate easier connection between the projections 64 of the moveable portion 24 and the channel 58 by guiding the projections 64 into the channel 58. Once connected, the moveable portion 24 may pivot relative to the body portion 22 to open the dispenser and allow for cutting of the bandage roll 12.
As discussed above, cutting of the bandage roll 12 may be done using the cutter 28. The cutter may extend through an unrolled portion of the bandage roll 12 during cutting and be received within a cutter recess 32B of the body portion. Similarly, as discussed above, the nub 30 of the moveable portion 24 may compress and seal the remaining portion of the bandage roll 12 by contact the bandage roll 12 and pressing it within a nub recess 32A of the body portion 22, thereby ensuring sterility of the remaining bandage roll. As such, even when the dispenser is closed, a user may se through a slot 40 on the body portion 22 how much bandage roll 12 remains within the dispenser.
Additionally, the body portion 22 may also include one or more abrasive surfaces 44. The abrasive surfaces 44 may be similar or different to those found on the moveable portion 44. Moreover, as mentioned above, the body portion 22 may include a support portion 76 that maintains a position of the dispenser during, before, and after use.
Additionally, as discussed above, a nub 30 of the moveable portion 24 may also compress the bandage during a cutting operation to seal a remaining portion of the bandage roll within the cavity of the dispenser. As such, the nub 30 may contact the bandage prior to the cutter 28, simultaneously to the cutter 28, or both to ensure a user need not contact the unused portion of the bandage, thereby maintaining sterility. For example, the nub 30 may seal the unused portion of the bandage within the cavity before cutting of the unrolled portion of the bandage is completed. The nub 30 may include one or more tapers 66 that converge towards a contact portion 68 of the nub 30. The contact portion 68 may be rounded, planar, tapered itself, or a combination thereof. However, it is envisioned that the contact portion 68 may seal the bandage within the nub recess 32A and the cavity of the dispenser by contacting a step 80 located within the nub recess 32A.
While a shape of the nub recess 32A may be complimentary to a shape of the nub 30, the nub recess 32A may alternatively or additional include one or more slopes 70 sloping down towards the step 80. When the dispenser is closed and the bandage roll is sealed within a cavity therein, an end of the bandage roll that is remaining unused may be located within a gap 72 formed between the nub 30 and the nub recess 32A. However, it should be noted that such a gap 72 may also be sealed within the dispenser when the dispenser is closed. As a result, a user may open the dispenser, contact only the portion of the bandage located within the gap 72, and unroll a desired amount for cutting.
