Solution Overview

Problem

Current methods for isolating healthcare practitioners from contagious patients during orotracheal interventions lack effective, portable, and easily adjustable barriers that can control aerosol transmission, especially in situations without negative pressure facilities or proper equipment.

Innovation Solution

A clear plastic protective barrier with circumferentially and cross-sectionally arranged fastening means, including sleeves with internal adhesive strips, providing a flexible and transparent isolation system that can be easily applied and adjusted for orotracheal maneuvers, along with an elastomeric stopper to seal endotracheal tubes, ensuring containment of aerosols and saliva microparticles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If simple means like boxes or blankets are used for separating patients from practitioners, then portability and simplicity are improved, but protection effectiveness and aerosol control deteriorate

Engineering Contradiction:
ImprovesimplicityVSAvoidprotection effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent employs a flexible transparent sheet made of plastic material that forms a barrier between patient and practitioner. This thin film provides effective aerosol containment while maintaining portability and ease of use, resolving the contradiction between simple construction and effective protection.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The transparent barrier sheet acts as an intermediary element between the patient and the practitioner, allowing visual contact and procedural visibility while physically blocking aerosol transmission. This mediator provides both protection and operational capability simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If complex means like negative pressure facilities are used, then aerosol control and protection effectiveness are improved, but device complexity and portability deteriorate

Engineering Contradiction:
Improveaerosol controlVSAvoidfacility complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential protective function from complex negative pressure facilities and implements it through a simple portable barrier system. By removing unnecessary complexity while retaining the core aerosol containment capability, the solution achieves effective protection without requiring sophisticated equipment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A flexible transparent sheet serves as the primary containment barrier, replacing complex mechanical ventilation systems with a simple physical barrier that effectively controls aerosol dispersion during orotracheal procedures.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If barriers are not properly adjusted and customized, then ease of operation is improved, but protection effectiveness and reliability deteriorate

Engineering Contradiction:
Improveease of adjustmentVSAvoidprotection effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The barrier system incorporates adjustable components including detachable fastening elements and flexible positioning capabilities that allow real-time adaptation to different procedural requirements and patient sizes, ensuring both ease of adjustment and effective protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The barrier is divided into functional sections with separate fastening mechanisms that can be independently adjusted and positioned, allowing flexible customization for different procedures while maintaining overall system integrity and protection effectiveness.

Inventive Principle:
Principle #1Segmentation
