Solution Overview

Problem

Traditional therapeutic wraps experience inconsistent heat transfer due to fluid warming as it passes through the wrap, leading to fluctuations in temperature and discomfort for patients, with increased flow rates or lower inlet temperatures required to maintain effectiveness, which can cause discomfort or injury.

Innovation Solution

A therapy wrap with a variable thermal insulating layer positioned along the fluidic channels, featuring different insulating members with varying thickness and thermal resistivity to manage temperature deltas, ensuring consistent heat transfer and patient comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the inlet temperature is lowered to maintain heat transfer effectiveness, then cooling performance is improved, but patient comfort decreases and injury risk increases

Engineering Contradiction:
Improvecooling performanceVSAvoidpatient comfort and injury risk
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent implements localized thermal insulation at the inlet region and along fluidic channels, creating different thermal characteristics in different zones. This allows the inlet fluid to be maintained at a lower temperature for effective heat transfer while preventing excessive cooling at the body interface through strategic insulation placement.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The thermal insulating members are positioned in advance along the fluidic channels to prevent excessive heat transfer from occurring. This beforehand cushioning approach protects the patient from potential injury by ensuring that even if inlet fluid is very cold, the insulation prevents direct excessive cooling of the body tissue.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Stability of the object's composition

If thermal insulation is added to prevent fluid warming, then temperature consistency is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature consistencyVSAvoidwrap structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses flexible thermal insulating members that can conform to the wrap structure, maintaining temperature consistency without requiring rigid or complex insulation systems. These thin, flexible insulating layers integrate smoothly into the existing wrap design, minimizing added complexity.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The thermal insulating members are positioned within or alongside the existing fluidic channels and wrap layers, nesting the insulation function within the current structure. This nesting approach adds temperature stability functionality without significantly increasing overall device complexity or requiring separate independent systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

Temperature-controlled therapy wrap for treatment of at least a portion of an animate body including a fluid bladder including an inlet, an outlet, and at least one fluidic channel connecting the inlet to the outlet; and a thermal insulating member on the fluid bladder only directly adjacent the inlet and extending along the at least one fluidic channel. The therapy wrap may be adapted to compensate for a temperature delta in the wrap. The therapy wrap may include an insulating layer of one or more insulating members. The insulating layer is dimensioned and configured to have different coefficients of heat transfer. The insulating layer may have varying thicknesses and materials to achieve varying heat transfer rates. Also disclosed is a method of administering a temperature-controlled treatment to an anatomical body part.
