Medical Accessory Lifecycle Tracking via Segmented Usage Data

Solution Overview

Problem

Medical devices with consumable components face challenges in ensuring timely replacement, as existing systems rely on rough estimates for accessory lifespan, leading to either premature or delayed replacement, affecting device performance and regulatory compliance.

Innovation Solution

A system that uses unique identifiers stored on memory chips in medical device accessories to track usage data across devices, allowing for accurate determination of the true end-of-life based on actual usage, enabling automatic reordering and ensuring compliance with regulatory standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If rough estimates are used for accessory lifespan, then device complexity is reduced, but measurement precision of accessory usage deteriorates

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system divides the accessory lifespan tracking into multiple independent components: a use counter on the accessory itself, a use counter in the medical device, and a central server database. Each component stores and manages a portion of the usage data, allowing precise tracking without requiring a single complex system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A central server acts as an intermediary between multiple medical devices and accessories. The server receives usage data from devices, aggregates it with data from other devices that have used the same accessory, and provides comprehensive lifespan information back to the devices, enabling accurate tracking without direct complex interactions between devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If actual usage data is tracked across multiple devices, then measurement precision of accessory end-of-life is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The tracking system is segmented into three distinct parts: (1) local use counters in each medical device that independently track usage, (2) a central server that aggregates data from multiple devices, and (3) a database storing the cumulative usage history. This segmentation allows precise end-of-life determination while keeping individual device complexity low.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The central server provides universal functionality by serving multiple medical devices and managing accessory lifecycle data for the entire system. Rather than each device having its own complex tracking system, the universal server handles data aggregation, calculation, and dissemination for all devices, reducing overall system complexity while improving measurement precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems and methods described herein relate to tracking indications of use for medical device accessories to track and determine end of life for the sensors as well as to enforce an end of life for various accessories. The indications of use may be tracked by a medical device to which the accessory is connected, with the accessory uniquely identified by an identifier that the medical device may associate with the indications of use. The indications of use and identity information for the accessory may be conveyed to a cloud-based system for tracking lifespan of accessories. The medical device and/or cloud-based system may determine an end-of-life based on the specific indications of use and communicate the lifespan, expiration, or expected expiration to an owner or user of the accessory.
