Sealed Urine Collection Assembly for Sterile Sampling and Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for draining urine from non-ambulatory patients, such as indwelling catheters and standard intermittent catheter trays, are inefficient and pose risks like catheter-acquired urinary tract infections (CAUTIs) and exposure to bodily fluids, lacking a seamless and sterile urine collection system.
Innovation Solution
A collection assembly with a vessel having two external layers, a movement control device, and a connector device, designed to efficiently collect and sample urine while minimizing infection risk, featuring a sealed design and a controlled fluid release mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indwelling catheters are used to drain urine from non-ambulatory patients, then urine drainage is achieved, but the risk of catheter-acquired urinary tract infections (CAUTIs) increases
Solution Approach 1:
The collection assembly is divided into separate functional components: a collection receptacle for urine accumulation, a sampling port for sterile sample collection, and a drainage mechanism. This segmentation allows sterile sampling without compromising the closed system, thereby reducing infection risk while maintaining drainage effectiveness
Solution Approach 2:
The patent introduces a closed collection assembly as an intermediary system between the patient's bladder and the external environment. This closed system acts as a mediator that enables urine drainage and sampling without direct exposure to contaminants, eliminating the infection pathway associated with traditional indwelling catheters
2Reliability
If standard intermittent catheter trays are used, then urine collection is possible, but exposure to patient urine and bodily fluids increases
Solution Approach 1:
The closed collection assembly serves as a protective intermediary barrier between the healthcare practitioner and the patient's bodily fluids. The assembly includes sealed components and a controlled sampling mechanism that allows fluid collection without direct exposure, thereby maintaining collection capability while eliminating exposure risks
Solution Approach 2:
The collection assembly utilizes sealed flexible membranes and closed-system construction to contain bodily fluids. This sealed barrier system allows for sterile sampling and complete drainage while preventing contact between the practitioner and infectious materials
3Reliability
If intermittent catheterization is performed, then urine drainage is achieved, but the need to gather supplies for sterile procedure increases complexity
Solution Approach 1:
The patent combines multiple functions into a single integrated collection assembly: the collection receptacle, sampling port with sterile barrier, drainage mechanism, and measurement markings are all merged into one device. This eliminates the need to gather separate supplies for catheterization, sampling, and measurement, reducing procedural complexity while maintaining drainage effectiveness
Solution Approach 2:
The collection assembly is designed as a multi-functional device that performs urine collection, sterile sampling, volume measurement, and complete drainage all through one system. This universal design eliminates the need for multiple separate supplies and procedures, simplifying the overall process while maintaining clinical effectiveness
