Solution Overview

Problem

Existing patient care devices (PCUs) face challenges in reducing medication errors due to complex administration rules and the lack of real-time verification of medication orders, especially in emergency situations where electronic medical records (EMRs) may be unavailable, leading to potential data entry errors.

Innovation Solution

A patient care unit (PCU) system that retrieves remote data from a healthcare server, determines the next medication order based on clinician history and context, and provides automated confirmation through a user interface, eliminating the need for manual scanning and ensuring correct administration parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If barcode labels or RFID tags are scanned for automatic entry into PCU, then data entry errors are reduced, but verification correctness with patient treatment regimen is not ensured

Engineering Contradiction:
Improvedata entry accuracyVSAvoidmedication order verification
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system retrieves the user's dispensing history from remote servers and uses it to generate suggested medication orders. The PCU then presents these suggestions to the user for confirmation, creating a feedback loop that verifies the medication order against the patient's treatment regimen. This feedback mechanism ensures both accurate data entry and verification of correctness.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by automatically retrieving dispensing history, analyzing it to determine suggested medication orders, and preparing confirmation prompts before the user actually enters medication orders manually. This preliminary preparation reduces the burden on users and minimizes data entry errors while ensuring verification against treatment regimens.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If manual entry of medication orders is performed in EMR-unavailable situations, then PCU can operate without EMR system, but data entry errors increase

Engineering Contradiction:
Improveoperational independence from EMRVSAvoiddata entry accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system uses an intermediary mechanism by storing and retrieving dispensing history from remote servers that act as a mediator between the PCU and the EMR system. When EMR is unavailable, the PCU can still access this intermediary storage to obtain accurate medication order information, maintaining operational independence while preserving data entry accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates copies of medication order data by storing dispensing history remotely. These copies can be retrieved and used at the PCU even when the original EMR system is unavailable, ensuring data entry accuracy is maintained through access to verified historical data.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If multiple medication orders with complex administration rules are managed, then comprehensive patient treatment is achieved, but risk of medication errors increases

Engineering Contradiction:
Improvetreatment regimen complexityVSAvoidmedication error reduction
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs self-service by automatically analyzing the user's dispensing history, determining suggested medication orders with appropriate administration rules, and presenting them for confirmation. This automated analysis reduces the complexity burden on users while maintaining comprehensive treatment regimen management, thereby reducing medication errors.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces the mechanical process of manual medication order entry and verification with an automated computational system that retrieves historical data, analyzes administration rules, and generates suggested orders. This substitution reduces errors associated with complex manual management of multiple medication orders.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If PCU has automated drug administration capability, then medication administration efficiency is improved, but information may become outdated or superseded

Engineering Contradiction:
Improvemedication administration efficiencyVSAvoidinformation currency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback by continuously retrieving updated dispensing history from remote servers and comparing it with the PCU's current medication order information. When superseding information is detected, the system updates the PCU accordingly, ensuring information currency while maintaining automated administration efficiency.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system introduces dynamics by making the medication order information in the PCU updateable and adaptable based on retrieved dispensing history. Rather than static automated administration, the system dynamically updates information when new data is available, ensuring both efficiency and information currency.

Inventive Principle:
Principle #15Dynamics
