Abstract: Various intraoral gastrointestinal access devices, systems, and methods are disclosed herein to deliver substance directly to a target gastrointestinal tract site of a user while bypassing other portions of the gastrointestinal tract. The intraoral gastrointestinal access devices can be anchored within a mouth of a user and are generally concealed when not in use.

Abstract: 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.
