Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for securing IV lines, such as tape and elastic bands, can cause displacement, allergic reactions, skin irritation, and tissue damage due to tightness, especially in delicate skin or burn patients.

Innovation Solution

An IV line clasp with a contoured recess to hold the IV equipment and adjustable cotton straps that secure via fasteners, eliminating the need for tape and ensuring a comfortable, non-restrictive fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tape is used to hold IV line, then IV line is secured to patient body, but IV line can shift and become dislodged, and tape can cause allergic reactions and skin irritation

Engineering Contradiction:

ImproveIV line securityVSAvoidskin irritation and allergic reactions

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the harmful tape element from the IV securing system entirely, replacing it with a clasp mechanism that holds the IV line through mechanical engagement with the patient's clothing or skin, eliminating contact between tape adhesives and sensitive skin surfaces

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The clasp acts as an intermediary device between the IV line and the patient's body, providing a secure hold through a contoured recess that cradles the IV hub, while the adjustable straps provide indirect securing through clothing or skin without direct adhesive contact

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If elastic band is used to secure IV, then IV line is held in place, but circulation can be cut off and tissue damage can occur

Engineering Contradiction:

ImproveIV line positioningVSAvoidcirculation restriction and tissue damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs adjustable straps with fasteners that allow dynamic adjustment of the securing force, enabling the caregiver to tighten or loosen the straps as needed to maintain IV security while preserving blood flow, unlike fixed elastic bands that continuously apply restrictive force

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The clasp concentrates the securing force locally at the IV hub through its contoured recess, while the adjustable straps distribute the remaining force across a broader area of clothing or skin, preventing the concentrated pressure that causes tissue damage with elastic bands

Inventive Principle:

Principle #3Local quality

3Reliability

If tape is used to secure IV, then IV line is attached to patient body, but IV line can become dislodged when patient moves

Engineering Contradiction:

ImproveIV line attachmentVSAvoidIV line position stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent combines multiple securing mechanisms into one integrated clasp device: the contoured recess that cradles the IV hub, the adjustable straps that wrap around the limb, and the fasteners that lock the straps in place, creating a multi-point attachment system that resists dislodgement from patient movement

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present invention is an IV line clasp that has a contoured recessed channel provided in a head that is designed to receive and hold the IV equipment securely and has adjustable cotton straps attached on either side of the head that secure together on their ends via hook and loop fasteners to hold the IV in place on the patient's body without the use of tape.
