The present invention relates methods and apparatuses for storing and dispensing adhesive bandages. More particularly, the present invention relates to methods and apparatuses for storing and dispensing a continuous feed of adhesive bandages which enable single-handed application of an adhesive bandage.
Adhesive bandages are a widely available and well known component of typical first aid care practices applied to safely and cleanly treat and protect common cuts and wounds. Persons wishing to be prepared for emergencies may store a supply of adhesive bandages in first aid kits or home medicine cabinets, and commercial, retail, or industrial facilities may desire or may be regulated to have a variety of emergency first aid products including adhesive bandages available for persons working in or visiting those facilities. Adhesive bandages are available in a wide variety of shapes including but not limited to strips, spots, patches, butterfly, and other shapes for specialty applications such as fingers or knuckles, each of which may be produced in a variety of sizes. Several manufacturers produce adhesive bandages, which are often sold in packages as a quantity of a specific shape and size, in variety packs which may include quantities of different shapes and sizes, or in combination with other emergency-related products as part of a first-aid kit.
Initially developed in the early twentieth century, a typical adhesive bandage may be formed from four basic components, including an adhesive strip or sheet, a non-adhesive pad which is typically absorbent, a removable backing which prevents the bandage from adhering to its packaging, and a bag or wrap surrounding the bandage which may also serve to keep the bandage sterile. In a common example, an adhesive bandage may be formed from a fabric strip having an adhesive material on one side, a cotton pad located about centrally on the adhesive side of the strip, a two-part, overlapping coated paper backing fully covering the cotton pad and adhesive side of the strip, and a coated paper bag surrounding the bandage which may be provided with one or more tabs which can be pulled in order to tear the bag open in order to expose the bandage. Adhesive bandages may also be formed from a range of materials, for example the adhesive strip or sheet may be formed from plastic, latex, foam, or tricot, the non-adhesive pad may be formed from other absorbent materials or may be configured to apply or release a topical or non-topical medicine, and the backing, bag, or wrap may be formed from a suitable coated or non-coated plastic material.
In a typical application, a person who may have sustained a wound may need to locate a package if individually wrapped adhesive bandages, remove a single wrapped bandage from the package, open the bag surrounding the bandage, remove each of the two overlapping backing strips, and then apply the adhesive bandage over the wound. In this typical application, the step of opening the bag may include pulling on two available tabs of the bag intended to assist in tearing the bag open, which commonly involves gripping each tab with a thumb and one or more fingers of each hand. Additionally, the step of removing the overlapping backing strips may involve holding the bandage with one hand while simultaneously manipulating the bandage into a semi-folded orientation with a second hand and locating, exposing, and pulling an exposed portion of the first of the two overlapping backing strips, and then changing the way in which the bandage is held in order to be able to locate, expose, and pull on a portion of the second of the two backing materials.
Indeed, such a typical application may necessitate the availability of two hands, which may be problematic for the person if the wound were sustained on an arm, wrist, hand, knuckle, or finger. Likewise, the process just described may be problematic where, for example, the person may have a need to apply pressure to the wound with one hand or otherwise not have two hands available to prepare the bandage for application to the wound. Consequently, there is a need for apparatuses and methods for storing and dispensing adhesive bandages which enable convenient, single-handed application of an adhesive bandage without interfering with the sterile nature of the adhesive bandage's packaging.
These and other needs in the art are addressed in one embodiment by a continuous-feed bandage dispenser which may principally comprise a housing, a cover, and a plurality of rotating elements which may comprise one or more spools and one or more rollers, wherein a continuous feed of bagged adhesive bandages may be dispensed from a spooled loading system.
These and other needs in the art are addressed in one embodiment by a continuous-feed bandage dispenser which may principally comprise a housing, a cover, a plurality of rotating elements which may comprise one or more spools and one or more rollers, and a bandage magazine, wherein a continuous feed of bagged adhesive bandages may be dispensed from a magazine loading system.
These and other needs in the art are addressed in one embodiment by a method of dispensing an individual adhesive bandage from a continuous feed of adhesive bandages, wherein a bagged adhesive bandage may be dispensed having its bag separated, removed, and collected internally within a continuous-feed bandage dispenser comprising a spooled loading system, with the dispensed adhesive bandage presented for single-handed application. The method may comprise individual steps of loading, storing, and dispensing a plurality of bagged adhesive bandages, wherein the dispensing may further comprise individual steps of separating, removing, and collecting a bag within which an adhesive bandage may be stored.

Cover 220 may be provided with one or more apertures for accommodating one or more rotating elements. For example, in embodiments, cover 220 may be provided with apertures for accommodating each of the spools 230, and apertures for accommodating each of two rollers 140, or a projection or axle each thereof. Cover 220 may be provided with additional apertures through which fasteners (not shown) may secure cover 220 to housing 210.
The rotating elements of bandage dispenser 200 may comprise one or more spools 230 and one or more rollers 240, each of which may be generally cylindrical in shape, having a central axis, a length 231, 241, and opposing planar surfaces 232a,b, 242a,b. In embodiments, spool 230 and roller 240 may be provided with a curved surface adjoining each of its opposing planar surfaces, and may be solid or hollow. In alternate embodiments, the curved surface of spool 230 and roller 240 may comprise one or more apertures, or may be formed as a frame of a curved surface. Length 231,241 may be any length suitable for rotatably disposing spool 230 and roller 240 between housing 210 and cover 220, and may correspond to one or more dimensions of an adhesive bandage, Each spool 230 may comprise a circumference defined by cross sectional diameter 233, and may be formed having, or may be provided with, a centrally located axle or projection 234 (not shown) on at least one of the opposing planar surfaces 232a,b which may be adapted to be received into aperture 214 of housing 210 or a corresponding aperture of cover 220, and about which spool 230 may rotate. Similarly, each roller 240 may comprise a circumference defined by cross sectional diameter 243, and may be formed having, or may be provided with, a centrally located axle or projection 244 (not shown) on at least one of the opposing planar surfaces 242a,b which may be adapted to be received into aperture 215 of housing 210 or a corresponding aperture of cover 220, and about which roller 240 may rotate. In alternate embodiments, in place of centrally located axel or projection 234,244, spool 230 or roller 240 may be provided with a centrally located bore suitable to receive a fastener through a corresponding aperture of housing 210 or cover 220, which may allow spool 230 or roller 240 to rotate about its central axis, Cross sectional diameter 233 of spool 230 may be any cross sectional diameter suitable for storing a capacity of spooled adhesive material within housing 210, or suitable for collecting a corresponding capacity of remnant peeled bandage bags within housing 210, and may correspond to one or more dimensions of an adhesive bandage.

Spool 230 and roller 240 may be formed through any known manufacturing process, for example an additive manufacturing process such as 3D printing, and from any material suitable for sterile storage of medical grade products, for example polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polyvinyl alcohol plastic (PVA), polycarbonate (PC), stainless-steel, aluminum, carbon fiber, or combinations thereof.
In embodiments, each of the one or more spools 230 may be caused to rotate manually, or by powered or automated form of rotation, or may be mechanically in communication with any of the one or more spools 230 such that a pulling force applied to an adhesive bandage at dispensing port 217 may at least one of the one or more spools 230 to rotate in synchronization with the rate at which the adhesive bandage is dispensed through dispensing port 217.
Bandage magazine 250 may be defined by a volume located within the volume formed by housing 220 and bandage magazine wall 256, and may be having internal height 251, internal width 252, and internal depth 253, each of which may correspond to one or more dimensions of an adhesive bandage. In embodiments, internal height 251, internal width 252, and internal depth 253 may be selected so as to volumetrically accommodate a stacked plurality of individual bagged adhesive bandages 254, each of which may be similarly oriented in space, such that an end of each bagged adhesive bandage which may be preferred to be opened first at dispensing port 217 may be located adjacent to a common internal surface of bandage magazine wall 256.
One or more biasing elements 255 (not shown) may be disposed within bandage magazine 250. In embodiments, biasing element 255 may be in contact with an internal surface of bandage magazine 250 and a surface of an individual bagged adhesive bandage located in a bottom-most position of stacked plurality of individual bagged adhesive bandages 254. In alternate embodiments, biasing element 255 may be in contact with an internal surface of bandage magazine 250 and a plate or shelf which may be in contact with a surface of an individual bagged adhesive bandage located in a bottom-most position of stacked plurality of individual bagged adhesive bandages 254. Biasing element 255 may function to bias stacked plurality of individual bagged adhesive bandages 254 toward and against the curved surface spool 230b such that spool 230b may contact an individual bagged adhesive bandage located in a top-most position of stacked plurality of individual bagged adhesive bandages 254. In this manner, as a top-most bagged adhesive bandage may be removed from the stacked plurality, biasing element 255 may cause the stacked plurality to rise in the internal magazine such that a next top-most may be biased toward and against the curved surface spool 230b. Biasing element 255 may thus be disposed within bandage magazine 250 in a compressed configuration, and provided with an effective biasing length which may allow a bottom-most bagged adhesive bandage of the stacked plurality to be biased against spool 230b after each of the preceding bagged adhesive bandages have been removed from the stacked plurality.
Referring now to
In the first embodiment illustrated by
Upon loading spool 130b into bandage dispenser 100, the initial feed of the continuous feed of adhesive bandages may be loaded into bandage dispenser 100 so as to be fed linearly along the directed pathway illustrated in
As illustrated by
Bandage dispenser 200 may be loaded with two spools of continuous feeds of adhesive material, for example a suitable form of tape, each of which may be initially disposed on spool 230b and spool 230c, such that an adhesive side of the material is oriented outward and away from a center the respective spool onto which it may be loaded. Spool 230b may be disposed in bandage dispenser 200 such that the adhesive side faces stacked plurality of individual bagged adhesive bandages 254 (downward as illustrated), and the continuous feed may be wound around roller 240a to be collected by spool 230a in the directional path illustrated. Spool 230e may be disposed in bandage dispenser 200 such that the adhesive side faces the continuous feed between spool 230b and 230a (upward as illustrated), and the continuous feed may be wound around roller 240b to be collected by spool 230d in the directional path illustrated.
Bandage dispenser 200 may also be loaded with a plurality of individual adhesive bandages arranged in a stacked configuration and disposed in bandage magazine 250 such that a preferred end of each of the plurality of individual adhesive bandages is aligned against a common internal surface of bandage magazine wall 256. In embodiments, the arrangement may be based upon an alignment of one or more pull tabs of the bag, or an alignment of one or more backings of each adhesive bandage, such that upon being ejected from dispensing port 217 a lip or tag of one of the backings may be caused to be initially or fully separated from the dispensed adhesive bandage by separating projection 218.
When stacked plurality of individual bagged adhesive bandages 254 are loaded into bandage dispenser 200, a top-most side of a top-most individual adhesive bandage of the stacked plurality may be brought into interference contact against the adhesive surface of the continuous feed between spools 230b and 230a. In operation, rotation of spool 230a in an anti-clockwise direction will serve to pull the continuous feed and in-turn “grab” the top-most adhesive bandage of the stacked plurality. Upon being fed away from the stack, the continuous feed may proceed to “grab” the next top-most adhesive bandage of the stacked plurality as a result of biasing element 255 biasing the stacked plurality upward and against spool 230b. Similarly, the continuous feed between spool 230c and 230d may be caused to adhere to a side of each individual adhesive bandage opposite of the side adhered to by the continuous feed between spool 230b and 230a. In this manner, a continuous feed of adhesive bandages may be formed by bandage dispenser 200 and prepared for dispensing through dispensing port 217.
The method by which bandage dispenser 200 dispenses an individual bandage may then proceed similarly to that of bandage dispenser 100, whereby the bag of the bagged adhesive bandages approaching rollers 240a,b may be caused to be torn open resulting from a pulling force generated as each of the continuous feeds of adhesive materials following separate paths to spools 230a,d. Upon being torn open, an individual adhesive bandage may be caused to be dispensed or ejected through dispensing port 217, free of its bag. As the individual adhesive bandage is dispensed, separating projection 218 may catch, and in turn cause to separate, fully or partially, at least one of the backings of the exposed individual adhesive bandage, thus presenting the individual adhesive bandage with a portion of its adhesive surface exposed in a manner where it may be both removed from bandage dispenser 200 and applied in a single-handed operation.
Each of the embodiments and methods just described allows single-handed removal and application of an adhesive bandage, with the adhesive bandage remaining in its sterile bag until dispensed. Additionally, each of the embodiments and methods provides for the collection if remnant bandage bags within the housing of bandage dispenser 100,200, with the size and capacity of bandage dispenser 100,200 and its constituent components correlating to a desired initial capacity of adhesive bandages.
Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations may be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
