CONTAINER FOR AN AUTOMATIC INJECTOR
A container for an automatic injector provides safe, quick, and easy access to an automatic injector stored therein. The container includes tactile features that allow a user to easily determine the orientation of the container by feel alone. A hinged cap with an automatic spring assist feature allows a user to single-handedly open the container quickly and easily to remove the injector from the container without interference from the cap. The container is structured to receive the automatic injector needle end first and has a puncture resistant bottom to prevent the needle of the injector from piercing through the body wall of the container. The container also provides safe storage of a discharged automatic injector, with the hinged cap spring assist feature automatically closing the cap enough to prevent the discharged injector from falling out of the container.
This claims the benefit of U.S. Provisional Application No. 60/925,283, filed Apr. 18, 2007, the entire contents of which are incorporated herein by reference thereto.
FIELD OF THE INVENTIONThe invention relates generally to containers for carrying, storing, and protecting automatic injectors. Specifically, the invention relates to containers that allow users to open and close the containers quickly and easily and to carry and store used and unused automatic injectors safely. The invention also relates to an attachment device for carrying two of the containers together.
BACKGROUND OF THE INVENTIONMany individuals unfortunately must carry medication with them at all times. In some cases, the medication is contained in an automatic injector. An automatic injector is a device that performs intramuscular or subcutaneous administration of a therapeutic agent. An advantage of automatic injectors is that they contain a measured dose of a therapeutic agent in a sealed sterile cartridge. Automatic injectors allow for quick and simple injection of the therapeutic agent in emergency situations without the user having to measure dosages or see the needle as the agent is being injected. Automatic injectors are used, for example, to treat anaphylactic (severe allergic) reactions and to administer antidotes for certain poisons, such as chemical nerve gas.
In those cases where an automatic injector is carried by an individual at all times, the injector is likely to be exposed to various physical and environmental stresses that may damage the injector or the therapeutic agent stored inside. For example, exposure to heat and light may cause the therapeutic agent stored inside the injector to degrade. Also, an automatic injector may inadvertently activate if dropped or jostled. And once the automatic injector has been discharged, exposure to the used needle is a risk that should be prevented in those injectors that do not have a needle cover to automatically extend over the used needle.
Many automatic injectors are therefore stored, before and after use, in a container referred to as a carry pack. In general, there are two types of automatic injector carry packs. The first type is a soft carry pack, usually made of neoprene or other soft material. These carry packs are usually large in size and attach to a belt or other item of clothing. To access the stored injector, the user must unzip the carry pack. Unfortunately, many soft carry packs are not puncture resistant and thus cannot be used to store a discharged automatic injector with an exposed needle.
The second type of carry pack is a smaller, tube-shaped container that can fit easily into an individual's pocket. The tube-shaped containers are usually made of a rigid material and are generally equipped with one of two types of caps. The first is a screw cap which requires the user to unscrew the cap, and the second is a push-cap which requires the user to remove the cap completely from the body of the container.
These known automatic injector carry packs have the disadvantage of requiring two hands to open the carry pack, whether to unzip the carry pack or to unscrew or pull off the cap of the carry pack. Such actions can be difficult or even impossible to perform when a user is suffering from an attack and needs to quickly access the automatic injector contained in the carry pack.
In view of the foregoing, there is a need for a container that safely accommodates an automatic injector before and, depending on the type of injector, after use and that allows a user to easily and immediately access the injector contained therein.
SUMMARY OF THE INVENTIONIn accordance with the invention, containers for automatic injectors store and protect the injectors from damage and protect the therapeutic agent stored inside the injector from degradation and contamination. Also, containers of the invention help prevent the automatic injector stored therein from accidentally activating. Furthermore, the containers allow the user or caregiver to quickly open the container and remove the automatic injector stored therein and then, depending on the type of automatic injector, safely store a used injector with an exposed needle after use until proper disposal can be made.
The automatic injector containers have a cylindrically-shaped, enclosed hollow body having an open end and a closed end opposite the open end. The closed end is preferably puncture resistant, and the open end is sized to receive an automatic injector there through. The body of the container includes a lower portion extending from the puncture resistant end that is preferably sized and shaped to receive only the needle end of the injector.
The containers of the invention include a cap that has a top portion, a bottom portion, and a hinge connecting the top and bottom portions. The bottom portion is affixed to the open end of the body and the top portion is sized and shaped to close the open end of the body. The cap also has a front and a back, with the hinge located on the back. The front bottom portion of the cap may extend farther along the body in a direction toward the closed end than the back bottom portion of the cap to facilitate tactile identification of the front of the container.
The hinged cap advantageously allows the user or caregiver to single-handedly open the container and access the automatic injector. The hinged cap has automatic spring assist features that help open and close the cap. When the user or caregiver applies sufficient force to initially open the cap (i.e., unsnap the cap from the container), the hinge causes the cap to automatically spring farther open to a position that creates a clear path unobstructed by the cap. This allows the automatic injector to be easily and quickly removed (as compared to known containers where unsnapping the cap only partially opens the cap, leaving the path at least partially blocked by the cap). Additionally, when the user or caregiver applies sufficient force to initially move an open cap towards closure, the hinge causes the cap to automatically spring farther to a partially-closed position that prevents the automatic injector from falling out of the container, such as, for example, when the container is tilted or held at an angle that would otherwise allow the injector to slide or drop out of the container.
Other advantageous features of the container include a body that has a shape to (1) prevent or inhibit the container from rolling on a slightly inclined surface and (2) receive the automatic injector in preferably only one orientation—needle end first. The body also has a puncture resistant bottom end to (1) prevent an unused automatic injector from piercing the container should it unintentionally activate while in the container and (2) ensure that discharged automatic injectors with exposed needles can be safely stored. In one embodiment, the puncture resistant end is contoured in such a way as to bias the needle end of the automatic injector off-center, thereby making the needle more likely to bend or cripple than to penetrate the bottom end of the container.
In some embodiments, the body includes contours and textures that make grasping and handling of the container easier and help the user or caregiver identify the orientation of the container by feel alone. The contours and textures may also help identify the type of automatic injector stored inside the container and may help differentiate between the packaging and the automatic injector itself.
In a preferred embodiment of the invention, the containers include a first pair of contoured areas and/or a second pair of contoured areas on the exterior surface of the body. The first pair of contoured areas are preferably positioned opposite each other on the body and are sized and shaped to facilitate attachment to an optional attachment device of the invention, which can be used to attach pairs of automatic injector containers together and/or one or more containers to an individual's belt, jacket, or other article of clothing or personal possession (e.g., a backpack). The second pair of contoured areas may also be positioned opposite each other on the body and are sized and shaped to facilitate grasping and/or orienting of the container by hand. Furthermore, the first and second pairs of contoured areas are positioned preferably opposite each on the body of the container.
The invention is also directed to automatic injector kits that include an automatic injector, a container for the automatic injector, and an attachment device.
The features and advantages of the invention will be apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
Automatic injector containers of the invention can store many types of automatic injectors, such as, for example, the EPIPEN® automatic injectors by Meridian Medical Technologies. Inc. Typical automatic injectors have a housing that contains a cartridge. The cartridge has one or more chambers containing a therapeutic agent. The housing has a needle end that usually contains a needle assembly attached to a chamber. The housing also has an activation end opposite the needle end that usually contains an activation assembly. The activation assembly includes a stored energy source such as a compressed spring. Activation of the activation assembly typically causes a sequence of internal movements within the housing that forces the needle into a user and the therapeutic agent through the needle.
Container 10 is sized to receive and enclose an automatic injector therein. In some embodiments, the container is longer in the longitudinal direction than an automatic injector received therein. A user is then encouraged to tip the automatic injector out of the container rather than reach into the container to grasp the automatic injector. This is preferred because some automatic injectors have a safety pin located at the end of the injector nearest the open end of the container (i.e., opposite the needle end). Thus by having the user or caregiver tip out the injector from the container instead of reaching into the container to grasp it, the chances of accidentally activating the automatic injector are less.
Cap 14 includes a top portion 30, a bottom portion 32, and a hinge 34. Hinge 34 connects top portion 30 to bottom portion 32. The cap has a front 16 and a back 18, and hinge 34 is located on back 18 of cap 14. In certain embodiments, the back of cap 14 is aligned longitudinally with one of the second pair of contoured areas 25/26, and the front of cap 14 is aligned longitudinally with the other of the second pair of contoured areas 25/26. Bottom portion 32 is affixed to the top, open end of container 10/10X (referred to collectively hereinafter as “the container” or just “container 10”). The cap can be any shape, provided it uses the hinge mechanism of the invention and securely attaches to (and in some cases provides an airtight seal with) the body of the container when closed. The front 16, bottom portion 32 of cap 14 preferably extends farther along body 12 in a direction toward puncture resistant end 20 than the back 18, bottom portion 32 of cap 14. Cap 14 also has a flap 35 located on the front 16, top portion 30 and has a contoured area 38 located on the front 16, bottom portion 32. Contoured area 38 allows the user to identify the front of the cap, as well as easily engage the flap to open the cap for easy access or disposal of an automatic injector. Also, such a feature advantageously allows the user to single-handedly open the container for access or disposal of an automatic injector.
In accordance with the invention, the spring assist feature of the hinge provides the cap with an automatic spring-open state and an automatic spring-almost-closed state. The spring-open state allows the automatic injector to be easily removed from the container. because the injector is not obstructed by the top portion of the cap when the cap is in the spring-open state. The spring-almost-closed state prevents the injector from falling out of the container, such as, for example, when the top of the container is tipped downward or while a person holding or carrying the container is running or otherwise moving. because the position of the cap in the almost-closed state blocks the exit path of the injector.
Additionally, in some embodiments, when the cap is closed (i.e., snapped shut), the container is not air tight (i.e., not hermetically sealed). In some of these embodiments, the cap includes a vent hole.
The cap preferably include features to prevent an automatic injector from rattling (i.e., moving freely) within the container. As shown in
Located on exterior surface 24 of body 12 is at least one contoured area. As shown in
As shown in
As also shown in
The overall “S” shape of the clip reduces the amount of force needed to remove a container from the clip, as compared to a more conventional double C-clip. The “S” shape of the clip allows the containers to act as levers, making removal of the containers easy. Additionally, texture on the outer surface of the attachment device makes the device easy to grip and preferably encourages users to replace the containers in the attachment device once the automatic injector has been used. The attachment device can also include a suitable attachment assembly for carrying the device on a belt or otherwise securing the device to an article of clothing or personal possession, such as a back or fanny pack.
As shown in
The containers of the invention can be made of any suitable material. Suitable materials include those that can form a container as described herein and that will safely contain an automatic injector before and, depending on the size and type of injector, after use. Suitable materials include, but are not limited to, polymers. Suitable polymers include, but are not limited to, polyurethanes, polyisobutylene and its copolymers, silicones, polyethylenes and polyesters. Other suitable polymers include polyolefins, polyisobutylene, ethylene-alphaolefin copolymers, acrylic polymers and copolymers, vinyl halide polymers and copolymers such as polyvinyl chloride, polyvinyl ethers such as polyvinyl methyl ether, polyvinylidene halides such as polyvinylidene fluoride and polyvinylidene chloride, polyacrylonitrile, polyvinyl ketones, polyvinyl aromatics such as polystyrene, polyvinyl esters such as polyvinyl acetate: copolymers of vinyl monomers, copolymers of vinyl monomers and olefins such as ethylene-methyl methacrylate copolymers, acrylonitrile-styrene copolymers, ABS resins, ethylene-vinyl acetate copolymers, polyamides such as Nylon 66 and polycaprolactone, alkyd resins, polycarbonates, polyoxyethylenes, polyimides, polyethers, epoxy resins, polyurethanes, rayon-triacetate, cellulose, cellulose acetate, cellulose butyrate, cellulose acetate butyrate, cellophane, cellulose nitrate, cellulose propionate, cellulose ethers, carboxymethyl cellulose, collagens, chitins, polylactic acid, polyglycolic acid, polylactic acid-polyethylene oxide copolymers and combinations of the foregoing.
The cap and body of the containers can be made of the same or different materials. For example, in some embodiments, the cap may be made of polypropylene and the container may be made of polyester or poly(ethylene terephthalate) (PET).
Additionally, the cap and body of the containers are preferably made of a material capable of blocking, absorbing or otherwise inhibiting the transmission of at least some wavelengths of ultraviolet (UV) light. For example, a UV absorbing agent can be added to the polymer from which the cap and the container are formed. UV blocking or absorbing capability helps to ensure that the therapeutic agent within the automatic injector is not degraded or otherwise compromised by exposure to UV light, even if the container is significantly light permeable.
The containers of the invention may also be made of a transparent, translucent or opaque material, or any combination thereof. For example, the caps of the containers can be made from an opaque, colored material. Using colored caps can help a user or caregiver easily identify which type of automatic injector is in which container. Additionally, the body can be a combination of transparent material and translucent material. Transparent material can form windows through the container so that the user can (1) identify what type of automatic injector is in the container, (2) determine whether it has been used and/or (3) read the instructions on the injector.
The containers of the invention may also serve as product packaging for an automatic injector and can thus be distributed with an automatic injector inside. Additionally, the exterior surfaces of the body of the containers, as well as the caps of the containers can be used for product labeling, usage directions, or other necessary indicia. Such labeling can be printed on labels and then affixed to the containers or printed or otherwise directly imposed on the surfaces of the containers during manufacture. For example, transparent windows can be used as branding areas to display trademarks or other branding materials.
Also, translucent textured material may be used to form particular portions of the container, such as, for example, the contoured areas where the user is most likely to grasp or hold the container. Using a textured surface on portions of the container increases the user's ability to grasp and hold on to the container.
Containers of the invention may have other useful features. As shown in
The invention has been described in connection with the preferred embodiments. These embodiments, however, are merely examples, and the invention is not limited to them. It will be understood by those skilled in the art that other variations and modifications can be easily made within the scope of the invention and that the invention is limited by only the following claims.
