Shieldable Swab Assembly with Slidable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sampling swabs are prone to contamination and disease transmission due to exposure during specimen collection, leading to analytical errors and increased risk for healthcare personnel.
Innovation Solution
A shieldable swab assembly with a slidable cover assembly made of resilient material and strings that encloses and protects the collector tip, allowing it to be opened and closed along the elongated shaft to prevent contact with surrounding areas, reducing contamination and disease transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sampling swabs are used without protective covers, then the device complexity is low and ease of manufacture is high, but the collector tip is exposed to environmental and secondary contaminations leading to analytical errors
Solution Approach 1:
The swab assembly is divided into separate functional components: a collector tip, an elongated shaft, and a slidable cover assembly. The cover assembly itself is segmented into a hollow cover and a slider, allowing independent movement and protection of the collector tip while maintaining operational simplicity.
Solution Approach 2:
The collector tip is pre-enclosed within the hollow cover before the sampling procedure begins. This preliminary protective action prevents exposure to environmental contaminants during storage and transport, ensuring the collector tip is ready for immediate use in a sterile state without requiring complex sterilization procedures.
2Ease of operation
If the collector tip contacts surrounding areas during sampling, then the ease of operation is high, but secondary and environmental contamination occurs leading to analytical errors
Solution Approach 1:
The cover assembly is designed with sliding capability along the elongated shaft, transitioning between closed and open states. During sampling, the cover remains closed to protect the collector tip, then slides open to allow collection, and automatically or manually closes again to prevent contact with surrounding areas during withdrawal.
Solution Approach 2:
The hollow cover acts as an intermediary barrier between the collector tip and the external environment. It allows the collector tip to perform its sampling function while maintaining physical separation from contaminating surfaces, effectively mediating the interaction between the sampling tool and the patient's anatomy.
3Productivity
If sampling swabs are used for infectious diseases without protection, then productivity is high with disposable items, but disease transmission risk to healthcare personnel increases
Solution Approach 1:
The hollow cover provides preliminary protection to the collector tip before it contacts potentially infectious materials. This pre-established barrier reduces the risk of aerosol generation and direct contact with infectious agents during the sampling procedure, protecting healthcare personnel while maintaining efficient disposable swab usage.
Solution Approach 2:
The hollow cover is constructed as a flexible protective shell that encloses the collector tip. This thin-walled structure provides effective biological containment against infectious materials while allowing the swab to remain disposable and maintain its sampling functionality, thereby reducing disease transmission risk without compromising productivity.

AI summary
A shieldable swab assembly comprising an elongated shaft, a collector tip, and a slidable cover assembly. The slidable cover assembly may comprise a hollow cover and a plurality of strings extending through a central duct of the elongated shaft. The elongated shaft may pass through proximal and distal apertures of the hollow cover. The hollow cover may be capable of moving along a longitudinal axis of the elongated shaft. Each respective string of the plurality of strings may comprise a distal end that may extend outwardly from a distal opening of the elongated shaft and may be attached to an outer surface of a distal end of the hollow cover. The each respective string of the plurality of strings may further comprise a proximal end that may extend outwardly from a proximal opening of the elongated shaft. Proximal ends of the plurality of strings may be tied to one another.
