Abstract
Low-dosage syringes for use in administering small dosages of medicine are disclosed. An illustrative low-dosage syringe can include an elongate syringe barrel having an interior chamber adapted to receive a supply of fluid, a plunger member slidably disposed within the interior chamber, and a tip member defining an inner lumen in fluid communication with the interior chamber. The configuration of the syringe barrel, including the wall thickness of the barrel relative to the outer diameter and to the length of the barrel, may permit small dosages of medicine to be accurately administered while also allowing the user to easily manipulate the syringe barrel with their fingers.
