Definitions

• the present invention relates to devices used in the medical field and in particular to devices for preventing or reducing medication errors such as Preventable Adverse Drug Reaction Events (ADE's).
• AD's Preventable Adverse Drug Reaction Events
• Medication errors are frequent events in hospitals and in emergency care situations and often have tragic consequences. Such errors include administration of the wrong drug, drug overdoses, and overlooked drug interactions and allergies. They occur for many reasons, including illegible handwritten prescriptions and decimal point errors.
• Medication errors result in approximately 250,000 non-fatal injuries each year (Harvard Medical Practice Study). More than one million serious medication errors occur every year in U.S. hospitals.
• Computer Information systems have been developed that claim to reduce medication errors significantly.
• Computer physician order entry (CPOE) systems are electronic prescribing systems that intercept errors when they most commonly occur - at the time medications are ordered. With CPOE, physicians enter orders into a computer rather than on paper. Orders are integrated with patient information, including laboratory and prescription data. The order is then automatically checked for potential errors or problems.
• CPOE systems do not prevent ADE's which are caused by poor identification of syringes in which medication has already been drawn-up.
• Prepared dosages, already drawn up into syringes are used often in medical emergency situations and also in timetabled events such as surgery, where trays of medication needed over the course of the surgery are prepared before the surgery begins and are laid out on trays.
• intravenous medications are one of the most difficult medications to identify once they have been drawn up into a syringe. Almost all intravenous medications appear as a clear liquid when viewed through a syringe sidewall with virtually no way of distinguishing between medications once drawn up.
• This clip consists of a single piece of durable yet flexible molded plastic with two semicircular c-shaped rings placed side by side a short distance apart.
• a syringe and vial can be easily placed in a beginning position by placing them parallel to the openings of the c-shaped rings. When gentle pressure is applied, the rings flex slightly outward around the circumference of the syringe or vial. The vial or syringe are in the final position when they have been pressed into the base of both c-shaped rings with the curved portions of the rings and endpoints holding them firmly into place.
• Both of these methods have the common disadvantage that the measurement indicators (dose markers) in the syringe body are often obscured, affecting the user's ability to read the dosage that has been drawn up into the prepared syringe.
• the other main disadvantage with using adhesive tape to attach a use ampoule to the syringe body portion is that the broken ampoule pose a risk of sharps injury to a user not taking absolute care when handling the syringe with the broken ampoule attached.
• a clip to secure a syringe to a medication ampoule said ampoule having a neck surrounding a neck passage
• said clip including: a base; an ampoule engaging portion projecting from the base, said ampoule engaging portion being a projection to be received within said passage and resiliently compressed by said neck so as to be resiliently urged into engagement with the neck to attach the ampoule to the clip; and a syringe engaging portion to releasably attach the syringe to the clip.
• said syringe engaging portion is a recess in said base within which a portion of the syringe is to be located so as to be releasably retained therein.
• said recess is located between a pair of resilient arms, the arms being resiliently urged apart to provide for location of the syringe in the recess.
• said recess is open in a direction away from said projection.
• said base has a first end adjacent which said projection is located, and a second end spaced from said first end, said second end having said recess.
• said base has a longitudinal axis, with said projection and recess being located on said longitudinal axis.
• said base has a longitudinal axis and said recess faces perpendicularly away from said longitudinal axis.
• said projection has a plurality of barbs to aid the projection to securely but releasably engage the neck.
• said projection is bifurcated longitudinally so as to provide two elongated arms that are resiliently deformed to move toward each other by engagement with the neck.
• said projection is provided by a plurality of elongated arms that are resiliently urged together by the neck.
• said syringe engaging portion is an arcuate socket within which a portion of the syringe is to be located.
• said socket is resiliently deformed by the syringe so as to be urged into contact with the syringe to aid in retaining the syringe releasably attached to the clip.
• said projection is a first projection
• said clip includes at least one further ampoule engaging projection.
• said recess is located between two projections of the clip.
• said clip includes a plurality of arms that engage externally of the neck.
• said arms are resiliently deformed when engaged with the neck so as to be urged into contact therewith to aid in releasably attaching the ampoule to the clip.
• said base is generally planar, and said projection extends generally normal to said base.

• Figure 5 is a schematic parts exploded isometric view of the syringe, ampoule and clip of Figure 1;
• Figure 6 is a schematic parts exploded isometric view of a modification of the clip of Figure 1 together with a syringe and two ampoules;
• a clip 10 that is used to secure an ampoule 13 to a syringe 11.
• the syringe 11 includes a hollow o cylindrical body 15 terminating at its forward end with a tip 16.
• the tip 16 frictionally engages the needle base 20 so that the needle 20 is secured thereto.
• a plunger 14 is slidably located in the body 15 and is movable relative thereto to draw liquid into the body 15 and to expel liquid through the needle 12.
• the syringe 11 would be operated to withdraw liquid from within the ampoule 11, and then inject the liquid. s Typically the clip 10 would be discarded.
• the ampoule 13 may be formed of glass or plastics and would include a neck 21 surrounding a neck opening 22 through which liquid passes with respect to the interior of the ampoule 13. Extending inwardly from the opening 22 through the neck 21 is a neck passage.
