Embodiment Construction

[0086] Embodiments set forth herein may include infusion systems, covers for such systems, system cartridges, and methods of making and using the same. These embodiments may be used when a prescribed fluid, such as contrast media or saline, is injected into a patient before and / or during a medical procedure (eg, a CT scan). These embodiments may include a syringe barrel (eg, a 200ml syringe barrel) having a base portion and a main portion that are manufactured separately and then assembled together. In some embodiments, the base portion includes surfaces having a refractive index configured to reflect optical signals propagating from the light source. The base portion may comprise an opaque material. Unlike prior known systems that rely on refraction, the syringe barrel is configured to activate a light sensor circuit in the injector head through reflection.

[0087] The cover may be a multipurpose cover. In the illustrated embodiment, the cover plate is configured to (a) p...

Abstract

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 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.
