(19) Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

(20) The presently disclosed subject matter is directed to an apparatus that allows individual adhesive strips to be easily and efficiently accessed by a medical professional. Specifically, FIG. 1 illustrates one embodiment of apparatus 5 defined by a series of pre-formed adhesive strips 10. As shown, the strips are offset and overlayed, providing for easy access by a user. In addition, each strip includes fold 15 that allows a medical professional to grasp an individual adhesive strip, remove it from the adjacent strip, and use it for a particular application. When an additional adhesive strip is needed, the medical professional can repeat the process with the next (e.g., topmost) adhesive strip until all of the strips have been used.

(21) FIG. 2a illustrates one embodiment of adhesive strip 10. As illustrated, each strip includes non-adhesive top side 20 and opposed adhesive bottom side 25. Each strip also includes first end 30 and opposed second end 35 that includes fold 15. The fold is formed by joining two portions of the adhesive side 25 together to form a non-adhesive section (e.g., a portion of the non-adhesive top side on the top and bottom surface) that can easily be grasped by a user to remove a single adhesive strip from the adjacent adhesive strip using an upward pulling motion, as discussed below. In some embodiments, the fold is permanent and cannot be unfolded.

(22) Alternatively, the fold can include liner 31 or any other non-adhesive material positioned at one end of the strip, as shown in FIG. 2b. The liner comprises a flexible, thin, elongated backing layer in the shape of a long strip. Any suitable type of backing layer can be used, including those that are commercially available. Examples of backing layers (also sometimes referred to as backing laminates, backing films, etc.) that could be used include polymeric films of polyester, polypropylene, polyethylene, ethylene/vinyl acetate copolymers, polyvinyl chloride, polyvinyl acetate, polyurethane, paper, foams, non-woven fabric, or woven cloth. However, the folded embodiment of FIG. 2a may be advantageous over embodiments comprising liner 31. For example, strips comprising a fold can be immediately used without having to remove the liner. In addition, there is no chance of the liner being prematurely removed and interfering with proper positioning with fold 15. Further, the fold is more secure than a liner.

(23) As set forth above, each adhesive strip includes adhesive bottom side 25. The term adhesive refers to any material that unites or bonds two surfaces together. Suitable adhesive materials can include (but are not limited to) pressure sensitive adhesives, heat activated adhesives, and the like. Thus, the adhesive can be selected from acrylic adhesive, hot melt adhesive, a structural adhesive, a silicone based adhesive, polyvinylmethyl ether and/or its copolymers, polyacrylates and/or their copolymers, polymethacrylates and/or their copolymers, polyacrylic acid and/or its copolymers, styrenic rubbers, polyvinylpyrrolidone and/or its copolymers, polyvinyl alcohol and/or its copolymers, polyurethanes, polyolefins, and combinations thereof. Any adhesive material or combination of materials can be used.

(24) In some embodiments, the adhesive can be configured as a skin-adhering adhesive. Examples of adhesive materials can include (but are not limited to) acrylic adhesives, silicone adhesives, elastomeric (rubber-based) adhesives, block copolymer adhesives, polyisobutene adhesives, urethane adhesives, polybutadiene adhesives, poly(ethylene-vinyl acetate) (PEVA) adhesives, polyvinyl ether adhesives, and hydrocolloids and gelatins such as karaya gum, guar gum, collagen, polysaccharide gum, locust bean gum, powdered pectin, gelatin, carboxymethyl cellulose, etc. In some embodiments, the adhesive material provides a fluid-resistant seal for the adhesive strip. A skin-adhering adhesive is configured to easily attach and remain attached to the skin of a patient, but can be removed with the application of light pressure without injuring or tearing the skin.

(25) As set forth above, the disclosed adhesive strip also includes non-adhesive top side 20. The term non-adhesive refers to a material that has low or no affinity for binding or adhering to another surface (e.g., the user's skin, medical tubing, medical devices, etc.). Suitable non-adhesive materials can include (but are not limited to) any of a wide variety of materials, such as polyester, nylon, carbon, polyolefin, fabric, polypropylene, paper, or combinations thereof.

(26) In some embodiments, adhesive material can be sprayed or fused onto the bottom side of the adhesive strip to confer the adhesive quality.

(27) In some embodiments, the top side, bottom side, or both the top and bottom sides of adhesive strip 10 are sterile. The term sterile refers to the characteristic of being free from infectious agents including bacteria, viruses, and bioactive RNA or DNA. For example, the sterile strip can be about 90-100% free from the cited infectious agents (e.g., at least/no more than about 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 99.9, or 100%). In other embodiments, the adhesive strip is not sterile.

(28) As shown in FIG. 2c, each adhesive strip 10 includes length 40 of about 0.5-6 inches (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, or 6 inches). The term length refers to the longest straight line distance from first end 30 to second end 35. Each adhesive strip can further include thickness 45 of about 0.01 to 0.5 inches in some embodiments. Thus, adhesive strip 10 can include thickness of at least about (or no more than about) 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, or 0.5 inches. The term thickness refers to the longest straight-line distance between the top and bottom sides 20, 25. As shown in FIG. 2c, adhesive strip 10 can further include width 50 of about 0.5-6 inches (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, or 6 inches). The term width refers to the longest straight line distance between side edges 60, 61. It should be appreciated that adhesive strip 60 can be configured with any desired dimensions and are not limited to the ranges given above.

(29) Each adhesive strip can be configured in any desired shape, such as (but not limited to) square, rectangular, triangular, diamond, pentagonal, hexagonal, heart-shaped, abstract, and the like. It should be appreciated that any shape can be used.

(30) As noted above, each adhesive strip includes fold 15. The fold facilitates removal of the adhesive strip from the adjacent adhesive strip so that it can be used. The fold also can help a medical professional easily remove an adhesive strip after use (e.g., from a patient's skin, tubing, and the like). In some embodiments, the fold can include a visible indication that visibly differentiates it from the main body of the adhesive strip. For example, the fold can be in a different color, pattern, or texture compared to the remainder of strip 10.

(31) In some embodiments, the fold makes up about 1-50 percent of the total surface area of the strip (e.g., at least/no more than about 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 percent), as shown in the embodiments of FIGS. 3a-3c.

(32) In some embodiments, the fold is configured with the same width as the rest of the strip (e.g., as shown in FIGS. 3a-3c). However, the presently disclosed subject matter is not limited and fold 15 can be configured to cover only a portion of the width of the strip, as illustrated in FIGS. 4a and 4b. In these embodiments, the strip can include a corner or other portion of the strip that is folded over upon itself as described above.

(33) As set forth above, bottom side 25 of the adhesive strip comprises an adhesive material. In some embodiments, about 100 percent of the surface area of bottom side 25 comprises adhesive material, as shown in FIG. 5a. Alternatively, the bottom side can comprise a portion of adhesive material 41 and a portion of non-adhesive material 42, as shown in FIG. 5b. The surface area of the bottom side of strip 10 can therefore comprise about 10-100 percent adhesive material.

(34) To form apparatus 5, a plurality of adhesive strips 10 are overlayed on top of the previous adhesive strip. The adhesive material on the bottom side of each strip functions to temporarily adhere that particular strip to the top non-adhesive top side of the previous strip as shown in FIGS. 6a and 6b. Thus, each adhesive strip is separated from adjacent strips by fold 15 which are not attached or joined to other strips. The process is repeated for a desired number of adhesive strips 10. In some embodiments, the disclosed apparatus can include about 5-50 strips or more (e.g., at least/no more than about 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 strips).

(35) After a desired number of adhesive strips are positioned together to form apparatus 5, the device can be adhered to any desired surface, allowing the medical professional access to the individual strips. For example, the first strip (the bottom-most strip of the apparatus) can be adhered to a work surface (e.g., a desk, patient bed, the wall), to the body of the medical professional (e.g., their arm or leg), or to any other desired surface. As strips are needed for a particular patient, the medical professional can easily grasp fold 15 of the top-most strip. The user can then peel the upper strip 10a from the adjacent adhesive strip 10b using a light upward pulling motion. In response to the pulling motion, the bottom adhesive surface 25 of strip 10a separates from the top non-adhesive surface 20 of adjacent strip 10b, as shown in FIG. 7. The process is repeated with successive strips until all the strips are needed.

(36) In some embodiments, the bottom-most strip can be adhered to support 100 that can be used on a particular surface. For example, as shown in FIG. 8, the support can include a double-sided adhesive (e.g., the top and bottom surfaces 101, 102 are adhesive allowing the adhesive strips to remain secured to the support and allow the bottom surface of the support to attach to a surface). The adhesive used on the bottom surface of the support can be stronger than the adhesive used on the strips to ensure that the apparatus remains stationary. Thus, the bottom surface of the support can be attached to a wall, a desk, table, or other item. The medical professional then has the plurality of strips readily accessible.

(37) When a strip is ready to be removed, it is peeled off the patient's skin or other surface by lifting up the fold and peeling the adhesive strip away. It can then be discarded using normal methods.

(38) The term medical professional refers to a person that is involved in the practice of medicine. Suitable medical professionals can include (but are not limited to) nurses, nurse's aides, doctors, surgeons, nursing home nurses, home healthcare workers, and the like. In some embodiments, the medical professional can be associated with human healthcare and/or veterinary care. It should be appreciated that the instant disclosure describes use of apparatus 5 in the medical field, the presently disclosed subject matter is not limited and the disclosed apparatus can be used in any field.

(39) The term patient as used herein can refer to a human. Specific examples of patients include (but are not limited to) individuals requiring medical assistance, individuals with limited function, individuals that have undergone or will undergo surgery, individuals that have undergone or will undergo a medical procedure, individuals that are being treated for a disease or disorder, individuals that have an injury that they are being treated for, and the like. In some embodiments, the patient can be an animal, such as a dog, cat, horse, etc.

(40) In some embodiments, each strip is overlayed to match the shape of the preceding strip, as shown in FIG. 6b. In other embodiments, the strips are offset (as shown in the embodiment of FIG. 1) to make grasping of fold 15 easier. The area of overlap can be about 0.1-1 inch (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1 inch).

(41) The disclosed apparatus provides many advantages over prior art devices. For example, apparatus 5 allows medical professionals to access adhesive strips easily and conveniently as needed during patient care. Instead of having to locate a source of tape, remove a desired amount of tape, and then avoid the sticky side from touching undesired surfaces, the user can quickly pull of an adhesive strip and use it directly.

(42) Apparatus 5 also saves valuable time of the medical professional, allowing them to spend more time with patients.

(43) The disclosed apparatus prevents the sticky side of an adhesive strip from being prematurely adhered to an undesired surface. In comparison, the disclosed apparatus allows the adhesive side to be covered by the adjacent adhesive strip, preventing premature sticking to a surface.

(44) Folded edge 15 allows the adhesive strip to be easily removed from apparatus 5. The folded edge also enables the medical professional to easily remove the strip when it is no longer needed (e.g., after a procedure has been performed).

(45) The foregoing description and examples have been set forth merely to illustrate the invention and are not intended to be limiting. Each of the disclosed aspects and embodiments of the invention may be considered individually or in combination with other aspects, embodiments, and variations of the invention. In addition, unless otherwise specified, the steps of the methods of the invention are not confined to any particular order of performance. Modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, and such modifications are within the scope of the invention.
