Catheterization Package Tray for Standardized Aseptic Urine Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheterization procedures lead to increased risks of catheter-associated urinary tract infections (CAUTIs) due to variations in urine sampling techniques, resulting in false-positive diagnoses and inappropriate antibiotic treatments.
Innovation Solution
A catheterization package and tray system that includes compartments for a urinary catheter, drainage bag, sampling-port access device, and swabsticks, with integrated instructions for aseptic urine sampling and catheterization, ensuring standardized and contamination-free procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional urine sampling procedures are used, then flexibility and ease of operation are improved, but contamination risk and diagnostic accuracy deteriorate
Solution Approach 1:
A sterile adapter is introduced as an intermediary component between the catheter sampling port and collection container. This adapter maintains the sterile field while enabling urine collection, thereby preventing contamination without compromising procedural flexibility.
Solution Approach 2:
The sterile adapter is pre-assembled and prepared before the catheterization procedure. By having the sterile barrier ready in advance, the risk of contamination during the sampling process is eliminated while maintaining ease of operation during the actual procedure.
2Ease of operation
If traditional catheterization procedures are used, then ease of operation is improved, but contamination risk increases
Solution Approach 1:
A sterile adapter serves as a mediator between the catheter and external environment, creating a sterile barrier that prevents contamination while allowing urine flow and sampling. This maintains procedural simplicity by requiring no additional complex steps.
Solution Approach 2:
The sterile adapter is designed as a disposable component that is discarded after single use. This eliminates cross-contamination risks between patients while keeping the system simple and easy to operate, as no sterilization or complex setup is required.
3Measurement precision
If standardized sampling procedures are implemented, then diagnostic accuracy is improved, but device complexity increases
Solution Approach 1:
The sterile adapter acts as a simple intermediary device that standardizes the sampling interface without adding significant complexity. It provides a consistent, sterile connection point that improves sample accuracy while maintaining device simplicity through its straightforward design.

AI summary
An intermittent catheter package including a plurality of components and a catheterization tray configured to facilitate a catheterization procedure. The plurality of components include a urinary catheter fluidly connected to a urine-drainage bag and a sampling-port access device configured to fluidly connect to a urine-sampling port of the urinary catheter or the urine-drainage bag for aseptic collection of one or more urine samples.The catheterization tray includes at least a first compartment, a second compartment, a third compartment, and a fourth compartment. The second compartment is connected to the third compartment Step-by-step surface instructions for performing the catheterization procedure are incorporated into the catheterization tray.
