## Background
BACKGROUND OF THE INVENTION
Medical emergencies pose a serious and prevalent threat to society. According to the Centers for Disease Control and Prevention (CDC), Americans suffered 29.6 million non-fatal injuries in 2009 and 31.5 million non-fatal injuries in 2010. Over 2.3 million non-fatal injuries each year are cuts or punctures. Emergency departments in the United States average approximately 400 visits for each 1000 people every year. The CDC further reports that injuries in the home result in about 30% of all injury-related emergency department visits. The National Institutes of Health and the Mayo Clinic recommend immediately covering wounds such as cuts, scrapes, and punctures with a sterile bandage.
SUMMARY OF THE INVENTION
Effective first aid requires easy and rapid access to sterile dressings appropriate to cover, protect, and help stop bleeding from a variety of wounds such as cuts, scrapes, and punctures. Consumers should have ready, ubiquitous access to dressings, such as sterile bandages. Moreover, bandages should be dispensed in a way that allows uncomplicated application with one hand. Because many injuries occur in the home, bandage dispensers should be inexpensive, yet attractive to encourage consumers to place them in multiple, easily accessed locations throughout their homes. Accordingly, we have identified a long-felt and unmet need for a consumer bandage dispenser with an inexpensive to manufacture design effective to retain a variety of bandage packs such that individual bandages are dispensed clean and ready to apply. Such a dispenser should also be easily refilled when bandage packs are depleted.
In one aspect, disclosed herein are systems for dispensing bandages comprising: a dispenser body comprising a receiving surface with a first retention element and a hinged flap with a second retention element, wherein the hinged flap is foldable to overlay at least a portion of the receiving surface; and at least one bandage pack disposed on said receiving surface, wherein said bandage pack comprises at least one individually wrapped bandage; provided that when the hinged flap is folded to overlay said receiving surface, a first retention element reversibly interlocks with a second retention element thus securely retaining said at least one bandage pack. In some embodiments, a first retention element, a second retention element, or both pass through at least one bandage pack. In some embodiments, the interlocking results from a first retention element fitting into a second retention element or vice versa. In some embodiments, the dispenser body comprises one or more pairs of opposing retention elements such that when a hinged flap is folded to overlay the receiving surface, each first retention element aligns with and opposes a second retention element.

EXAMPLES
The following illustrative examples are representative of embodiments of the methods, devices, and systems for dispensing individual bandages described herein and are not meant to be limiting in any way.
Example 1
Manufacture of a Bandage Dispenser
The inventor of the instant application created a low cost bandage dispensing system design. The design included a bandage dispenser body and a plurality of disposable bandage packs, which each included individually wrapped bandages.
The dispenser body design specified a rectangular dispenser body with a substantially flat back wall forming a surface for receiving disposable bandage packs and four side walls. The walls of the dispenser were designed to be 1.7 mm thick. The back wall and side walls of the dispenser body defined an open box shaped interior space that was rectangular having dimensions of 91.6 mm width, 104.6 mm height, and 10.0 mm depth. The design of the dispenser body included a receiving surface with two integral first retention elements. The first retention elements were hollow and tubular in shape. The design of the dispenser body also included a flap attached to one edge of the body by a thin, flexible strip of material forming a hinge. The flap was designed to fold about the hinge to overlay the receiving surface. The hinged flap was designed to include two integral second retention elements positioned to align with the first retention elements when the flap was folded to overlay the receiving surface. The second retention elements were designed to fit snugly within the hollow of the first retention elements forming a reversible interlocking mechanism. When interlocked, the retention elements held the flap in a folded configuration. The design of the dispenser body also included two third retention elements on the wall of the dispenser body opposite the hinged flap. The third retention elements were designed as tabs of material extending from the dispenser body wall parallel to the receiving surface. The third retention elements were offset from the receiving surface by 2.0 mm. The back wall of the dispenser body was designed with two mounting holes to facilitate mounting the dispenser on a surface.
The bandage dispensing system also included several types of bandage packs. The bandage pack design included a rigid cover folded to enclose a plurality of individually wrapped bandages. The individual bandages were designed to extend vertically beyond the upper edge of the cover such that the individual bandages are available to grasp and remove from the pack. The design of the packs included individually wrapped bandages bound to each other and to the cover, such that removal of an individual bandage from the pack causes the bound portion of the wrapper to be retained, thus freeing and partially exposing a bandage for application. The packs were designed to fit into the interior space of the dispenser body in contact with the receiving surface. Each bandage pack was designed with a circular, pre-formed hole. The design specified that when a bandage pack was disposed on the receiving surface of the dispenser body, the first and second retention elements passed through the pre-formed hole when the hinged flap was folded to overlay the receiving surface. When the first and second retention elements were interlocked with each other, the bandage pack was secured within the dispenser body. The cover of each bandage pack slid under a third retention element, thus securing the opposite end of the pack as well.
The bandage dispenser was injection molded of nylon material according to the specifications of the design. Two bandage packs were secured within each bandage dispenser to form the assembled system.
Example 2
Use of a Bandage Dispenser
A 39-year-old male cuts the thumb of his left hand while chopping vegetables in his home kitchen. He has previously placed three separate bandage dispensers in his home, one in his garage, one in his bathroom, and another in his kitchen pantry. When he realizes that he his injured, he uses a clean paper towel to apply pressure for one minute in order to slow the bleeding. Subsequently, he reaches for a bandage to cover and protect the wound as well as to further control bleeding. He grasps an individually wrapped strip bandage, which is bound in a bandage pack. Each individually wrapped bandage is bound to the others in the pack and to a moderately rigid bandage pack cover. The wrapper of each bandage is scored such that removal of an individual bandage from the pack causes the bound portion of the wrapper to be retained, freeing and partially exposing the bandage. The pack is further secured within a nylon bandage dispenser (manufactured as described in Example 1), which is mounted to the wall of his pantry.
When the man pulls upward on the individual, wrapped bandage, the mounted dispenser retains the bandage pack. The resulting force separates the bandage wrapper, freeing a partially unwrapped bandage, cleanly and ready for application. The bound portion of the wrapper is retained in the bandage pack. He applies the bandage to his injured thumb.
Example 3
Refilling of a Bandage Dispenser
Three days after the events described in Example 2, the injured man decides to replace the partially depleted bandage pack which he and other members of his family have used several times. To refill the bandage dispenser (manufactured as described in Example 1), he grasps the folded, hinged flap on the front of the mounted dispenser and pulls outward (e.g., toward himself) and downward. The first and second retention elements disengage and the flap folds (e.g., rotates about the hinge) downward, away from the receiving surface of the dispenser. The man next pulls the depleted bandage pack outward, away from the receiving surface, which removes the first retention element from the pre-formed opening in the bandage pack. He finally pulls the cover of the depleted bandage pack downward and outward to free it from under the third retention element.
He places a new bandage pack into the bandage dispenser, thus refilling the system. To do this, he slips the top edge of the bandage pack cover under the tab of the third retention element and pushes the hollow tube of the first retention element through the pre-formed opening at the bottom of the bandage pack. He then folds (e.g., rotates) the flap about the hinge so that it overlays the bandage pack and the receiving surface of the dispenser. He presses firmly on the folded flap to force the second retention elements on the hinged flap into the hollows of the first retention elements on the receiving surface, securing the bandage pack within the bandage dispenser.
