Slidable Tray Specimen Collector for Continuous Polyp Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional polyp traps require disassembly and interruption of the polypectomy procedure to collect multiple specimens, as they typically have single chambers or require manual handling of specimens, leading to inefficiencies and delays.
Innovation Solution
A specimen collector with a slidable tray and multiple chambers, allowing continuous suction and specimen collection without pausing the procedure, by positioning the tray to alternate specimen wells within the suction pathway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-chamber polyp trap is used, then the device structure is simple, but the procedure must be interrupted to remove specimens before collecting more
Solution Approach 1:
The device is divided into multiple chambers (first chamber, second chamber, third chamber) that can be independently filled with specimens. Each chamber has its own well positioned in the suction pathway, allowing simultaneous collection of multiple specimens without requiring device disassembly or procedural interruption.
2Productivity
If multiple chambers are used in a polyp trap, then multiple specimens can be collected, but the device complexity increases and requires rotatable caps or replacement assemblies
Solution Approach 1:
The device incorporates a movable tray that can be slid between different positions to selectively place different chambers into the suction pathway. This dynamic positioning mechanism allows the operator to access any chamber without rotating caps or replacing entire assemblies, maintaining simple device structure while enabling continuous multi-specimen collection.
3Reliability
If chambers are filled sequentially without tray movement, then the suction pathway remains continuous, but all specimens must be removed before collecting additional ones
Solution Approach 1:
Multiple chambers are pre-loaded with specimens during the procedure. The movable tray allows the operator to slide between chambers to remove specimens as needed while maintaining continuous suction. This preliminary preparation of multiple chambers eliminates the need to stop the procedure for specimen removal and replacement, preventing procedural delays while maintaining suction continuity.
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
Enables continuous polypectomy procedures with minimal interruption, allowing multiple specimens to be collected efficiently without stopping the process, maintaining consistent suction and reducing procedural delays.
Implementation Method 1
suction is applied to the outlet port and the inlet port is placed into fluidic connection with bodily matter to thereby draw the bodily matter into the specimen collector

AI summary
A specimen collector includes a sleeve with one or more interior walls defining a substantially hollow interior cavity. The sleeve further includes an inlet port in fluid communication with the interior cavity and an outlet port in fluid communication with the interior cavity. The sleeve further includes a first side aperture and a second side aperture. The specimen collector also includes a tray slidable within the interior cavity of the sleeve. The tray includes a first specimen well and a second specimen well that alternately may be placed into fluidic communication with the inlet and outlet ports.
