Patent ID: 11439760

Abstract:
Embodiments of this invention provide syringes calibrated for use with a predetermined liquid medication having an active pharmaceutical ingredient (API) at a particular weight per unit volume (w/v) concentration. Such syringes comprising a plunger and a barrel are configured such that the plunger, and/or an end portion of the plunger, is sealingly receivable through an opening at one end the barrel and within the barrel and slidingly moveable lengthwise within the barrel. This configuration allows formation of a reservoir inside the barrel into which the liquid medication may be loaded through an intake opening for the liquid medication at the other end of the barrel. Syringe barrels according to this invention possess line increments that form two or more graduated scales of API weight dosages extending lengthwise along the barrels. The increment lines provide for highly precise and accurate measurement of fine-increment weight dosages of the API.
