US 2023/0414864 A1 · METHODS AND SYSTEMS FOR OPTICAL-BASED FLUID CONTROL IN A FLUID DELIVERY SYSTEM

Abstract

Disclosed are systems and processes for an optical monitoring system for monitoring the dispensing of fluid from a fluid delivery device For example, a fluid delivery device may include a reservoir storing a fluid, a pump fluidically coupled to the reservoir, the pump comprising a drive mechanism to force the fluid from the reservoir, and an optical monitoring system. The optical monitoring system may include at least one light source operative to emit light incident on at least one element of the drive mechanism, and at least one sensor configured to receive the light reflecting off of the at least one element, wherein the at least one light source and the at least one sensor are arranged on a same side of the at least one element. Other embodiments are described.
