Movable Filter for Rapid Polyp Extraction in Sample Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sample collection devices are complex and time-consuming, wasting medical professionals' time due to the need to manually transfer polyp samples from a filtering screen to a collecting bottle.
Innovation Solution
A sample collecting device with a housing assembly featuring a collecting hole and a suction hole, where a filtering unit is positioned within the cavity, allowing for rapid separation of samples from impurities and easy removal of the filtering unit for quick transfer to a collecting bottle, eliminating the need to open the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional sample collection device with a separate filtering screen and collecting bottle is used, then the sample can be collected and separated, but the collection process becomes complicated and time-consuming requiring manual transfer of samples
Solution Approach 1:
The patent combines the filtering screen and collecting bottle into a single integrated device where the filtering structure is positioned within the bottle body. The suction hole communicates with the collecting hole through the filtering structure, allowing simultaneous filtration and collection in one device, eliminating the need for separate components and manual sample transfer between them.
Solution Approach 2:
The filtering structure is designed as a movable component that can be independently separated from the bottle body. This segmentation allows the filtering structure to be moved to a first position for sample collection and then to a second position for easy sample removal, enabling quick sample transfer without opening the device or manual manipulation of separate components.
2Ease of operation
If the filtering structure is fixed in position, then the sample collection is stable, but the sample removal process becomes complicated requiring device disassembly
Solution Approach 1:
The filtering structure is designed with movable capability, transitioning from a fixed position during sample collection to a different position during sample removal. This dynamic design allows the filtering structure to be moved between a first position (for collection) and a second position (for removal), enabling easy sample access without disassembling the device while maintaining structural integrity during operation.
3Loss of time
If the device is opened to remove samples, then the samples can be accessed, but the process becomes time-consuming and increases contamination risk
Solution Approach 1:
The patent extracts the filtering structure with the sample from the bottle body by moving it to a second position where it can be accessed through an opening in the bottle wall. This allows the filtering structure to be partially extracted or repositioned without opening the device, enabling quick sample removal through the side opening while maintaining the sealed environment and reducing contamination risk.

Function Achieved in This Case
This design significantly improves sample collection efficiency by allowing for rapid separation and transfer of samples, saving medical workers' time and simplifying the process.
Implementation Method 1
the bottle body is provided with a suction hole, and the filtering structure and the cover body are movably arranged, so that when the filtering structure is located between the cover body and the bottle body, the suction hole is communicated with the collecting hole through the filtering structure
