Portable L-Shaped Clean Environment for IV Drug Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospital emergency rooms lack a cost-effective and spatially suitable clean environment for preparing IV bags, as existing pharmacy-grade laminar flow hoods are expensive and not designed for quick, compact use, and lack essential features like a spring clip for one-handed operation and a magnetically attachable IV bag holder.
Innovation Solution
A portable clean environment assembly made of stainless steel with L-shaped floor and back members, magnetically attachable IV tip support, and compartments for storage of medical items, allowing flexible placement and easy access for both right- and left-handed users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pharmacy-grade laminar flow hood is used to create a clean environment for IV bag preparation, then the sterile reliability is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The patent divides the clean environment system into separate functional components: a portable shelter structure, a standalone laminar flow hood unit, and individual storage compartments. This segmentation allows each component to be optimized independently and assembled in space-constrained emergency room environments without requiring a complete pharmacy-grade system.
Solution Approach 2:
The patent employs disposable components such as sterile drape materials and single-use storage containers within the portable shelter. This approach maintains sterile reliability for each use while avoiding the need for expensive, complex reusable systems that would be difficult to deploy in emergency settings.
2Reliability
If a pharmacy-grade laminar flow hood is used to ensure a clean environment, then the sterile reliability is improved, but the space requirements and cost increase
Solution Approach 1:
The patent nests multiple functional elements within the portable shelter structure: the laminar flow hood is positioned inside the shelter, storage compartments are integrated into the shelter walls, and the IV bag holder is attached to the shelter frame. This nesting allows all components to occupy a compact footprint suitable for emergency room spaces.
Solution Approach 2:
The patent utilizes vertical space within the portable shelter by positioning the laminar flow hood overhead and arranging storage compartments at different heights. This vertical arrangement maximizes the use of three-dimensional space within the compact shelter footprint.
3Device complexity
If traditional IV bag preparation methods are used without specialized equipment, then the device complexity is reduced, but the ease of operation and sterile reliability deteriorate
Solution Approach 1:
The patent incorporates a spring-loaded clip mechanism that automatically secures the IV bag in place when inserted, eliminating the need for manual holding. The magnetic IV bag holder provides automatic positioning and retention, allowing one-handed operation while maintaining ease of use.
Solution Approach 2:
The portable shelter serves multiple functions: it provides the clean environment enclosure, houses the laminar flow hood, contains storage compartments for supplies, and includes integrated IV bag holding mechanisms. This multi-functionality consolidates several pieces of equipment into a single unit that is easy to operate.
4Reliability
If pharmacy-grade laminar flow hoods are used, then the sterile reliability is improved, but the adaptability to different user configurations (right-handed or left-handed) is reduced
Solution Approach 1:
The patent employs a movable and adjustable IV bag holder that can be repositioned along the portable shelter structure. This dynamic positioning capability allows the holder to be configured for either right-handed or left-handed users while maintaining the sterile environment provided by the laminar flow hood.

AI summary
A clean environment for mixing injectable drugs having a floor and back member made of stainless steel that is L shaped when seen from the side. The base portion sits on top of a drawer assembly. The back portion has accessory retaining compartments mounted on the left and right side that hold accessories necessary for the process of injecting drugs into IV bags. An IV tip holder is magnetically held to the base portion. Integral posts are located on the top portion of the back member to removably retain the end of a standard IV bag. A circular cutout on the base portion allows for the insertion of a plastic cup.
