Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional medical tubing stabilization methods allow for lateral, longitudinal, and internal movement of medical tubing relative to the patient, leading to trauma, contamination, and infection, particularly in urinary catheters, due to pistoning and lateral motion, which are not effectively addressed by existing solutions.

Innovation Solution

A medical tubing stabilization device comprising a tube stabilization patch with a tube engaging element and a patient attachment element, integrated into an adjustable medical garment, provides direct physical contact and equal pressure around the tubing perimeter to stabilize and immobilize the catheter, accommodating varying patient anatomies and sizes, reducing pistoning and lateral motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional medical tubing stabilization methods are used, then the device complexity is low, but the tubing movement and patient trauma increase

Engineering Contradiction:

Improvestabilization device structureVSAvoidtubing movement causing trauma and infection

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The stabilization device is divided into distinct functional segments: a stabilizing member with engagement features that contacts the tubing, a support surface that distributes pressure, and optional adjustable components. This segmentation allows each element to perform its specific function effectively while keeping the overall device relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stabilizing device acts as an intermediary element positioned between the medical tubing and the patient's body. It provides a stable interface that prevents direct movement of the tubing against the patient, thereby reducing trauma and infection risk without requiring complex integration into the catheter system itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the tubing is made more rigid to reduce movement, then the tubing stability improves, but the patient comfort and tissue damage worsen

Engineering Contradiction:

Improvetubing stabilityVSAvoidtissue damage from rigid tubing

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The stabilizing device provides localized stability at the specific point where the tubing exits or contacts the patient's body. The support surface is positioned to distribute pressure locally, preventing the tubing from moving against tissues while maintaining flexibility elsewhere in the tubing system, thus avoiding tissue damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The stabilizing device incorporates flexible components including a support surface that can conform to the patient's body contours and flexible engagement features that adapt to the tubing diameter. This flexibility allows the device to stabilize the tubing without exerting excessive rigid force on the patient's tissues.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If the stabilization device is made adjustable to accommodate varying patient anatomies, then the adaptability improves, but the device complexity increases

Engineering Contradiction:

Improveaccommodation of varying patient anatomiesVSAvoidadjustability mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stabilizing device incorporates adjustable elements that can be modified to match different patient anatomies and tubing configurations. The adjustability features allow the device to adapt its position, size, or configuration dynamically, ensuring proper fit and stabilization across various patient populations without requiring multiple different device designs.

Inventive Principle:

Principle #15Dynamics

AI summary

Devices, systems, and methods for stabilizing medical tubing protruding from a patient. In various embodiments of the present disclosure, a medical tubing stabilization device is provided that may include a tube stabilization patch and a complementary medical garment. The tube stabilization patch may be applied to a patient who has medical tubing or a catheter protruding from their body to reduce or dampen movement on the body from the medical tubing in relation to the patient. The medical garment may be worn by the patient and placed in combination with the tube stabilization patch to further reduce the relative movement of the medical tubing. The present disclosure may be directed to reducing the level of medical tubing movement, both externally and internally, that a patient may experience, which decreases the risk of infection caused by catheterization of patients.
