Syringe barrel and syringe-confirmation assembly

Abstract:

A syringe barrel includes a barrel body having a passage extending along a longitudinal axis between a tip opening and a load opening. The passage is configured to permit a plunger to advance therethrough along the longitudinal axis for driving a liquid through the tip opening. The barrel body includes a base portion that is configured to operably engage an injection system. The base portion has a body surface that is shaped to form a light-propagating space alongside the body surface. The light-propagating space extends to reflective ramps of the body surface. The reflective ramps have predetermined sizes and positions to reflect light signals radially away from the barrel body.
