Sterilizable Camera Rail for Pharmacy Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In pharmacy settings, especially in institutions like hospitals and correctional facilities, there is a challenge in effectively supervising and verifying the preparation of medications due to the need for direct oversight by a pharmacist, which can be hindered by the inability to sterilize conventional cameras and the complexity of managing image data in sterile environments, particularly when multiple preparations are occurring simultaneously.
Innovation Solution
A system and method that includes a camera mounted on a rail above the preparation surface, allowing it to be movable and sterilizable, with a wireless transmitter for data communication and external triggers for controlling camera functions, along with the use of identifier codes for verifying ingredients and workflow management, facilitating remote supervision and verification by a pharmacist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional camera is used for monitoring medication preparation, then image acquisition is possible, but the camera cannot be sterilized in a sterile environment
Solution Approach 1:
The system divides the imaging function from the sterile environment by using a camera positioned outside the sterile field, connected via a sterile barrier (such as a sterile drape with integrated camera or a sterile adapter). This allows the camera to remain non-sterile while still capturing images within the sterile preparation area, resolving the contradiction between needing image acquisition and maintaining sterility.
Solution Approach 2:
A sterile barrier or intermediary interface is introduced between the non-sterile camera and the sterile preparation area. This intermediary allows optical transmission while maintaining the sterile boundary, enabling image capture without compromising the sterility of the medication preparation environment.
2Reliability
If multiple cameras are positioned to monitor all preparation areas, then complete coverage is achieved, but the system becomes cumbersome and complex to manage
Solution Approach 1:
The system uses a single multi-functional camera or imaging system that can capture images across multiple preparation areas through strategic positioning, use of mirrors, or software-based pan-tilt-zoom capabilities. This single device performs the function of multiple fixed cameras, reducing system complexity while maintaining comprehensive monitoring coverage.
Solution Approach 2:
Multiple imaging functions (monitoring different preparation areas, capturing various angles, and managing image data) are merged into a single integrated system. The system combines hardware positioning mechanisms with software control to provide comprehensive coverage without requiring multiple separate camera systems, thereby reducing overall complexity.
3Measurement precision
If a pharmacist directly supervises each medication preparation, then verification accuracy is ensured, but the process is time-consuming and inefficient for high-volume preparations
Solution Approach 1:
The system enables self-verification through automated image capture and analysis. The camera system automatically captures images of the preparation process and compares them against the prescription requirements using image recognition and data processing algorithms. This allows the preparation system to verify its own work without constant pharmacist intervention, maintaining accuracy while increasing throughput.
Solution Approach 2:
The system implements automated feedback loops where captured images are immediately analyzed and compared against the prescribed medication parameters. The system provides real-time feedback on whether the preparation matches the prescription, allowing for rapid verification without requiring continuous pharmacist oversight, thus maintaining precision while improving productivity.

AI summary
A system for holding a camera for acquiring images of preparations includes a rail that can be mounted above a preparation surface. A camera carrier couples a camera with the rail such that the camera is movable relative to the rail and such that the camera can acquire images of preparations on the preparation surface.
