Solution Overview

Problem

Traditional pharmacy management techniques face challenges in ensuring the quality and safety of medical dose preparation, including reliance on physical labels that can lead to errors, inefficiencies, and potential for unprepared or duplicate doses, as well as labor-intensive record-keeping that may result in errors and inefficiencies.

Innovation Solution

A medical dose preparation management system that includes work stations equipped with imaging devices and metadata capture capabilities to guide technicians, track, and organize medical dose orders, reducing the need for physical labels and improving record-keeping through digital documentation and verification processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical labels are used to track medical dose orders, then the system is simple and easy to operate, but errors such as lost or damaged labels can lead to unprepared or duplicate doses

Engineering Contradiction:
Improvedose tracking accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical labels with digital copies stored in a database. Each medical dose order is represented by a digital record that can be accessed and tracked electronically, eliminating the risks associated with physical labels while maintaining the tracking function.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical system of physical labels and manual tracking with an electronic information system. The work station computer manages dose orders digitally, replacing the physical manipulation of labels with electronic data processing and storage.

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

2Productivity

If pharmacy technicians manually create and transcribe records for prepared doses, then the system requires minimal equipment, but labor-intensive practices result in errors and inefficiencies

Engineering Contradiction:
Improverecord-keeping efficiencyVSAvoidrecord accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The work station system automatically generates and manages dose preparation records without requiring manual transcription by pharmacy technicians. The system self-updates the dose order status and maintains accurate records through automated data capture and processing.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual record-keeping practices with an electronic system that automatically captures, stores, and manages dose preparation data. This substitution eliminates manual transcription errors and improves both efficiency and accuracy.

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

3Reliability

If pharmacists physically check doses by entering the clean room and observing materials, then verification is thorough, but it requires protective clothing and additional time

Engineering Contradiction:
Improvedose verification accuracyVSAvoidverification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates digital copies of dose preparation records and makes them accessible to pharmacists outside the clean room. Pharmacists can review electronic dose verification records without physically entering the controlled environment, maintaining verification accuracy while reducing time and resource requirements.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The work station system acts as an intermediary between the dose preparation process and pharmacist verification. It captures and transmits dose preparation data electronically, allowing pharmacists to verify doses remotely without direct physical presence in the clean room.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the label printer is the only source of work order information, then the system is simple, but prioritizing work becomes difficult and duplicate labels must be produced

Engineering Contradiction:
Improvework prioritizationVSAvoidtracking system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The work station system provides real-time feedback on dose order status, allowing pharmacists to see which doses have been prepared, are in progress, or are pending. This feedback mechanism enables effective work prioritization and eliminates the need to produce duplicate labels by providing up-to-date information on the current state of all dose orders.

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of work stations for use in medical dose preparation management system. A work station may include a camera stand. The camera stand may include a housing enclosing a camera and one or more light sources therein. As such, the camera and light sources may be directed at a medical dose preparation staging region to capture medical dose preparation images of the medical dose preparation staging region. The camera stand may include an adjustable support positionable in a plurality of positions to dispose the camera and light source relative to the medical dose preparation staging region. A base with a removable tray may be provided that include medical receptacle engagement features. The work stations may facilitate improved image quality, efficiency of work flows carried out at the work station, and administrative tasks such as cleaning.
