Syringe and kit for administering predetermined specific epinephrine doses
View Patent ↗The present invention relates to a syringe and medical kit, which allow for doses of epinephrine of 0.15 mg or 0.15 mL, 0.3 mg or 0.3 mL, and 0.5 mg or 0.5 mL, the most commonly prescribed doses which are utilized today in treating anaphylaxis or other allergic reactions. Currently, existing syringes may include many markings of ten or more dosages. Although these prior art syringes are useful, it is difficult to use them for a patient who must quickly identify a correct dose level among many other marks. The above problem can be addressed by a syringe design which has only a few dosage markings, which correspond to commonly used standard dosages for children and adults. When used with a standard concentration of 1:1000 epinephrine solution, such a device can rapidly provide a known quantity of medicine to a patient who is in urgent need of it.
1. A single-use device for administering one or more predetermined doses of epinephrine, consisting of:
a barrel having an internal reservoir configured to contain a volume of epinephrine constituting a single dose according to a manufacturer's or prescriber's recommended dosage of epinephrine, the barrel formed from a translucent material that is configured to transmit light to the reservoir and to provide a visible indication of an amount of epinephrine to be distributed, wherein said markings on the barrel indicating volumetric dosage consist of numerals and decimal points, arranged to form indicators in the numerical forms of only 0.15, 0.3, and 0.5;
a plunger manufactured from an opaque material having a color configured to enhance visibility of the plunger and dosage volume through the translucent material of the barrel, the plunger configured to be received in the barrel and axially movable relative thereto, the barrel including markings on the barrel indicating volumetric dosage for a predetermined patient characteristic and corresponding dose of epinephrine of concentration 1 mg/mL calibrated to a manufacturer's or prescriber's recommended dosage; and
a leur lock at a distal end of the barrel and configured to receive a needle and place the needle in fluid communication with the barrel.
