Visual Catheter Position Markings for Vasculature Feedback

1Reliability

If a catheter is secured in the vasculature, then the catheter remains in place for fluid infusion and blood withdrawal, but the catheter may become dislodged due to patient movement or improper securement

Engineering Contradiction:

Improvecatheter position stabilityVSAvoidpatient comfort and mobility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by providing position indicators (markings) on the catheter tubing before insertion. These markings allow the clinician to pre-determine and pre-mark the insertion depth and securement position, ensuring the catheter is positioned correctly from the start. This prevents dislodgement by establishing proper positioning in advance rather than requiring adjustment later.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through visual position indicators (colored bands, tick marks, or graduated markings) on the catheter tubing. These indicators provide continuous visual feedback to clinicians and patients about the catheter's position relative to the insertion site. When the catheter moves or becomes dislodged, the position indicators change, immediately alerting users to the position change without requiring complex sensors or electronics.

Inventive Principle:

Principle #23Feedback

2Reliability

If the catheter is firmly secured to prevent dislodgement, then catheter position stability is improved, but the securement method must withstand greater forces which may cause tissue damage or patient discomfort

Engineering Contradiction:

Improvecatheter position stabilityVSAvoidtissue damage from securement forces

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

3Ease of operation

If catheter dislodgement occurs, then patient comfort is maintained through minimal securement, but line restart is required which increases risk of sharps injuries and blood exposure

Engineering Contradiction:

Improvepatient comfortVSAvoidsharps injury risk

4Device complexity

If the catheter uses simple markings for position indication, then device complexity is reduced, but the precision of position detection may be insufficient

Engineering Contradiction:

Improveposition indicator systemVSAvoidcatheter position detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent applies local quality by using different types of markings at different locations on the catheter tubing. For example, graduated markings with specific intervals provide precise measurement at the insertion site, while colored bands indicate general zones (e.g., proper depth vs. too deep). This allows the simple marking system to provide both coarse and fine position information without adding electronic complexity.
