Disposable Liner Assembly for Hygienic Urine Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine collection systems are uncomfortable, prone to spills, and hygiene issues, and are limited in use for individuals with mobility impairments or restricted travel conditions, requiring improved methods for efficient and hygienic urine collection.
Innovation Solution
A urine collection system with a liner assembly that includes a lid with a vacuum port and collection port, allowing for easy disposal and reducing contact between urine and container surfaces, featuring a removable and disposable liner that can withstand vacuum pressures, and optional urine-solidifying agents to enhance cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional urine collection devices are used, then urine collection is achieved, but hygiene issues and spills occur due to direct contact between urine and container surfaces
Solution Approach 1:
The collection container is divided into two distinct parts: a reusable outer container and a disposable inner liner. The liner is inserted into the container, creating a barrier that prevents urine contact with the container surface. After use, only the liner needs to be disposed of, eliminating hygiene issues while keeping the container reusable.
Solution Approach 2:
The disposable liner acts as an intermediary barrier between the urine and the collection container. This intermediate layer prevents direct contact, solving the hygiene problem by allowing easy removal and disposal of the contaminated liner while the clean container remains reusable.
2Ease of operation
If bed pans are used for urine collection, then collection is achieved, but discomfort and spills occur
Solution Approach 1:
The liner is made from flexible material that can conform to the container shape and accommodate urine collection. The flexible nature provides user comfort while the sealed construction prevents spills, resolving the contradiction between comfort and reliability.
3Productivity
If urinary catheters are used, then urine collection is achieved, but discomfort, pain, and infections occur
Solution Approach 1:
The disposable liner is used for single-purpose urine collection and then discarded. This eliminates the risk of infections associated with reusable catheters, as each new liner is sterile and single-use, maintaining collection efficiency while preventing infections.
4Ease of manufacture
If conventional collection containers are used, then urine collection is achieved, but cleaning frequency and workload are high
Solution Approach 1:
The system separates the disposable liner from the reusable container. After use, the contaminated liner is discarded while the clean container is recovered and reused. This eliminates the need to clean the entire container, reducing cleaning frequency and time while maintaining collection functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system simplifies urine collection and disposal, reduces cleaning frequency and odors, and minimizes user and caregiver workload by preventing urine contact with container surfaces and allowing for easy liner replacement, improving hygiene and convenience.
Implementation Method 1
a pump configured to draw urine from the urine collection device by applying at least a partial suction force to a reservoir within the urine collection device
