Infusion Consumable Identification via Mounting Hole Depth

Solution Overview

Problem

Existing infusion devices require multiple sensors to identify various models of infusion consumables, leading to a complex and costly pump structure.

Innovation Solution

The infusion consumable features a mounting portion with a mounting hole that includes an identification member, where the depth of the mounting hole is greater than or equal to the thickness of the identification member, allowing a single identification member to differentiate multiple models based on depth and orientation.
