Solution Overview

Problem

Current blood collection methods are prone to contamination due to variability and human error in skin preparation, leading to potential bacterial contamination and non-compliance with standardized scrub times, which can result in infectious diseases and costly regulatory issues.

Innovation Solution

The development of blood collection devices equipped with integrated timers and display/audible output systems to guide phlebotomists through standardized skin preparation, ensuring proper cleaning and drying times, with automated restart functions to maintain compliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual timing methods (watch or wall clock) are used to monitor scrubbing procedures, then phlebotomists can perform skin preparation, but timing accuracy and compliance with standardized scrub times deteriorate due to human error and lack of synchronization between time pieces

Engineering Contradiction:
Improvetiming accuracyVSAvoidcompliance with standardized scrub times
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system performs timing automatically without requiring the phlebotomist to manually track time. The timer monitors and alerts the user when scrubbing duration is insufficient, making the system self-regulating and eliminating reliance on human timing accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to the user about scrubbing duration through visual and audible alerts. This feedback mechanism ensures the user is immediately informed when the standardized scrub time has been met or exceeded, enabling compliance verification.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If standardized scrubbing procedures are implemented, then blood contamination risk is reduced, but the complexity of the blood collection process increases due to additional timing and monitoring requirements

Engineering Contradiction:
Improveblood contamination riskVSAvoidblood collection process complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The timing and monitoring functions are integrated directly into the blood collection device itself, combining multiple functions (timing, alerting, compliance monitoring) into a single unified system rather than requiring separate external tools.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device automatically performs timing and compliance monitoring without requiring external timing tools or additional manual steps from the phlebotomist, making the standardized procedure self-executing through the device's built-in capabilities.

Inventive Principle:
Principle #25Self-service

3Loss of time

If multiple time pieces are used to initiate and monitor scrubbing procedures, then phlebotomists can track time intervals, but synchronization errors and non-compliance increase due to lack of time coordination between devices

Engineering Contradiction:
Improvescrubbing time trackingVSAvoidtime synchronization
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The single integrated timer performs both initiation and monitoring of scrubbing time automatically, eliminating the need for multiple time pieces and their associated synchronization problems. The system self-manages the entire timing process.

Inventive Principle:
Principle #25Self-service

AI summary

Apparatuses and methods of using them to collect blood, are provided, by first ensuring that the patient's skin is properly cleaned, to prevent contamination of the collected blood. One feature is a blood collection device configured to collect blood from a patient. Another feature is a scrub timer integrated into the device and configured to indicate to a user a scrub time period prior to beginning a blood draw process. The scrub timer can be configured to audibly and/or visually indicate to a user the start and stop times of a scrub cleaning process. In one embodiment, the scrub timer can be restarted, either manually or automatically, if the scrub cleaning process is not followed properly.
