Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The preparation of sterile compounded medications, such as chemotherapy drugs, requires a scale system with enhanced safety features and minimal footprint within a flow hood, while also ensuring user safety from toxic components, as existing systems lack efficient usability and safety measures.
Innovation Solution
A scale system with a platen and image capture device, integrated barcode scanner, and visual identifiers, which includes a disposable and absorbent surface for containment and visual indication of cytotoxic material exposure, ensuring compliance with sterility and safety protocols through image documentation and user interface guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scale is placed within a flow hood for sterile compounding, then sterility and safety are improved, but the available space is reduced due to the scale's footprint
Solution Approach 1:
The image capture device is integrated within the housing of the scale system, with the barcode scanner and other components nested within the same housing structure. This nested arrangement allows multiple functional components to occupy overlapping spatial volumes, significantly reducing the overall footprint of the scale system while maintaining all necessary functions for sterile compounding
Solution Approach 2:
The patent combines multiple functions into a single integrated scale system: weighing function, image capture function, barcode scanning function, and visual identification function are all merged into one compact unit. This consolidation eliminates the need for separate devices, reducing the total space required in the flow hood while ensuring sterility through the integrated design
2Reliability
If protective gear is worn during chemotherapy drug preparation, then user safety is improved, but ease of operation deteriorates due to bulky and cumbersome equipment
Solution Approach 1:
The system provides automated image capture and documentation without requiring manual intervention. The image capture device automatically captures images of the compounding process, and the system automatically tracks compliance parameters, reducing the operational burden on technicians wearing protective gear while maintaining safety protocols
Solution Approach 2:
The system incorporates real-time feedback through the user display that shows compliance status, captured images, and operational guidance. This feedback mechanism helps technicians operating with protective gear by providing clear visual information about system status and compliance requirements, improving ease of operation while maintaining safety
3Reliability
If a platen with disposable and absorbent surface is used, then sterility and contamination prevention are improved, but device complexity increases
Solution Approach 1:
The platen is designed as a separate, removable component that can be easily detached from the scale base. This segmentation allows the platen to be disposed of after single use, eliminating the need to dispose of or clean the entire scale system. The modular design maintains sterility while managing complexity through separable components
Solution Approach 2:
The platen is designed as a disposable component with an absorbent surface that can be discarded after a single use. This approach ensures sterility by eliminating cross-contamination risks between uses, while the relatively simple disposable nature of the platen (compared to sterilizing complex equipment) actually reduces overall system complexity management
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances user safety and sterility by preventing compounding until compliance is confirmed, providing visual and photographic documentation, and ensuring accurate drug preparation within specified tolerances, thus reducing exposure risks and improving operational efficiency in a compact and safe environment.
Implementation Method 1
at least a portion of the coating layer changes color in response to a cytotoxic material contacting the coating layer
Implementation Method 2
an absorbent material for absorbing any cytotoxic material on the platen

AI summary
A system for preparing and administering a prescribed fluidic pharmaceutical compound, such as a chemotherapy compound, includes a scale having a platen. The scale is in communication with a user display for displaying an output of the scale. An image capture device having a field of view for capturing at least one image of an object placed on the platen is provided in communication with the user display for displaying the captured image. The platen may include a visual identifier for identifying a portion of the field of view of the image capture device. The platen may also include a tackifier or absorbent material. The platen may be formed of a light-transmissible material.
