Control Vessel for Integrated Fluid Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical testing devices for bodily fluids, such as blood, require complex procedures and precise handling, often leading to inaccurate or compromised test results due to uncontrolled and rapid fluid release, which can be challenging for infrequent users, especially in point-of-care settings.
Innovation Solution
An integrated testing device with a reservoir for test fluid and a control vessel that allows for a controlled discharge of the fluid onto the test material, using a fluid delivery actuator to manage the flow rate, ensuring accurate and reliable fluid delivery through varying orifice sizes and shapes in the vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a reservoir is used to store test fluid, then the device can provide immediate testing capability, but the fluid may be released too quickly and uncontrolled onto the test material
Solution Approach 1:
The patent introduces a control vessel as an intermediary component between the reservoir and the test material. The control vessel receives fluid from the reservoir and provides controlled discharge onto the test material, acting as a mediator that regulates fluid flow rate and timing to ensure accurate test results while maintaining immediate testing capability
2Adaptability or versatility
If multiple separate components are used for testing, then the device can provide comprehensive testing functionality, but the procedure becomes complex and requires precise handling
Solution Approach 1:
The patent combines multiple testing components into an integrated device structure where the reservoir, control vessel, and test material are unified in a single device. This merging reduces procedural complexity and the number of separate handling steps required while maintaining comprehensive testing functionality
3Speed
If rapid fluid release is used, then the test can be completed quickly, but the fluid delivery becomes uncontrolled and may compromise test results
Solution Approach 1:
The control vessel is designed with dynamic flow control characteristics, allowing rapid initial fluid release followed by controlled discharge. The vessel's geometry and opening characteristics enable the system to transition from fast filling to precise, controlled delivery, maintaining both speed and measurement precision

AI summary
An integrated testing device is described, for example for testing bodily fluids. The device has a test component, a reservoir containing a test fluid, and a control vessel. The reservoir discharges test fluid into the control vessel, which discharges the test fluid in a controlled way to the test component.
