Solution Overview

Problem

Anesthetic gases often leak from breathing tubes during surgical procedures, contaminating the operating room environment and exposing personnel to health risks, while current securing methods can lead to hand contamination with infectious organisms.

Innovation Solution

A sanitary breathing tube securing device with radially perforated tear lines and adhesive tabs, combined with suction tubing attached to the anesthesia machine, effectively secures the tube and evacuates leaking anesthetic gases and aerosolized particles, preventing their dispersal into the room.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive surgical tape is used to secure the breathing tube, then the tube is secured to the patient's airway, but the gloved hand becomes contaminated with infectious organisms from oral secretions

Engineering Contradiction:
Improvetube securing effectivenessVSAvoidhand contamination with infectious organisms
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a barrier device (oral secretions barrier) as an intermediary between the patient's oral secretions and the anesthesiologist's gloved hand. This barrier prevents direct contact and contamination while allowing the tube securing procedure to proceed effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs disposable adhesive tape segments that are used once and then discarded, preventing the spread of infectious organisms from one patient to another and eliminating the need to sterilize reusable tape rolls between procedures.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Object-generated harmful factors

If the breathing tube cuff is inflated to higher pressures to prevent gas leakage, then anesthetic gas leakage is reduced, but patient discomfort and potential tissue damage increase

Engineering Contradiction:
Improveanesthetic gas leakageVSAvoidpatient discomfort and tissue damage
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a scavenging system as an intermediary component that captures anesthetic gases at the source (around the breathing tube cuff) and redirects them away from the operating room environment, allowing the cuff to maintain lower, more comfortable pressures while still preventing harmful gas leakage.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the harmful anesthetic gases from the operating room environment by using a scavenging system to remove and redirect the gases away from personnel, thereby preventing exposure without requiring higher cuff pressures.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If adhesive tape is reused across multiple patients, then productivity increases, but the risk of transmitting infectious organisms increases

Engineering Contradiction:
Improvetube securing efficiencyVSAvoidtransmission of infectious organisms
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs disposable adhesive tape segments that are used once and then discarded, preventing the spread of infectious organisms from one patient to another. Although this increases material consumption, it eliminates the risk of cross-contamination and the need for complex sterilization protocols.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent divides the adhesive tape into individual segments or segments that can be easily separated and discarded after single use, making the transition from reusable to disposable format practical and efficient.

Inventive Principle:
Principle #1Segmentation
