Catheter Tray Layout and Drainage System for CAUTI Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current urinary drainage systems face challenges with suboptimal drainage performance due to lower profile hospital beds and changes in venting systems, leading to urine pooling in tubing, which affects accurate urine output and flow rate measurements. Additionally, there is a need for a more reliable and safe method for inserting urinary catheters to reduce catheter-associated urinary tract infections (CAUTI).
Innovation Solution
The development of an improved catheterization package and tray with a layout and components optimized for ease of use and aseptic technique, including a drainage system designed to improve drainage performance by breaking surface tension, and the inclusion of povidone iodine swabs, hand sanitizer, and intuitive instructions to facilitate proper catheterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If lower profile hospital beds are used to reduce fall injuries, then patient safety is improved, but drainage performance deteriorates due to decreased height for urine drainage
Solution Approach 1:
The drainage system incorporates dynamic positioning capabilities where the collection bag and tubing can be adjusted to optimal heights and angles. The system allows for movement and repositioning to maintain effective drainage gradients even when the bed profile is lowered, ensuring urine flows efficiently without pooling in the tubing.
Solution Approach 2:
The invention introduces vertical dimension optimization by positioning the collection bag below the level of the catheter insertion point and using tubing with sufficient length and routing to maintain a downward slope. This dimensional arrangement ensures gravitational drainage works effectively regardless of bed height, solving the contradiction between low-profile beds and drainage performance.
2Ease of manufacture
If changes are made to venting systems in drainage tubing, then system design is improved, but urine pooling occurs leading to inaccurate measurements
Solution Approach 1:
The invention extracts the venting function from the main drainage pathway by incorporating a separate, dedicated venting tube that is distinct from the urine drainage tube. This separation ensures that venting adjustments do not interfere with urine flow, preventing pooling and maintaining accurate measurement capabilities in the collection bag.
Solution Approach 2:
The venting system acts as an intermediary component that regulates air pressure in the closed drainage system without directly contacting or mixing with urine. This mediator function allows for system pressure equalization and prevents backflow while keeping the urine drainage pathway clear and measurement-accurate.
3Reliability
If catheterization trays with optimized layout and instructions are implemented, then aseptic technique compliance is improved, but device complexity increases
Solution Approach 1:
The catheterization tray merges multiple functions into a single integrated unit: sterile component storage, step-by-step instructional guides, waste disposal containers, and cleaning supplies are all combined in one organized tray. This consolidation provides comprehensive aseptic support without requiring multiple separate devices, managing complexity through unified design.
Solution Approach 2:
The tray is pre-configured with all necessary components in their optimal positions before use. Instructions are pre-printed on the tray itself, and sterile items are pre-packaged and arranged for logical access during the procedure. This preliminary preparation reduces complexity during actual use by eliminating the need for assembly or searching for components.
