Solution Overview

Problem

Conventional convective blankets are designed for specific patient positions, requiring multiple blankets with different designs to effectively accommodate and cover patients in various positions, and often fail to provide adequate securement during medical procedures.

Innovation Solution

A warming blanket with a first and second sheet forming inflatable portions, an adhesive layer with release liners for securement, and air-permeable materials to allow warm air to communicate with the patient, enabling coverage in multiple positions and secure adherence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional convective blankets are designed for specific patient positions, then they can provide effective coverage for that position, but multiple different blanket designs are required for different patient positions

Engineering Contradiction:

Improvecoverage for different patient positionsVSAvoidnumber of different blanket designs required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The blanket is designed with a single universal configuration that can accommodate multiple patient positions (supine, lateral, prone, sitting) through the use of adjustable adhesive portions and release liners, eliminating the need for multiple position-specific blanket designs

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adhesive layer is divided into multiple separate adhesive portions with associated release liners that can be independently applied or removed, allowing the blanket to be adapted to different patient positions and body contours without requiring multiple complete blanket designs

Inventive Principle:

Principle #1Segmentation

2Reliability

If conventional convective blankets are used, then they can provide warming coverage, but they fail to provide adequate securement to the patient during medical procedures

Engineering Contradiction:

Improvesecurement to patientVSAvoidapplication and adjustment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Release liners are pre-positioned on the adhesive portions before the blanket is applied to the patient, allowing for controlled and easy application by simply removing the liners to expose the adhesive, which then securely adheres the blanket to the patient's body

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Release liners act as an intermediary layer between the adhesive portions and the patient's skin during application, protecting the adhesive until needed and facilitating easy, clean application without direct handling of the adhesive itself

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A warming blanket for warming a patient includes a first sheet including a first major surface of the warming blanket, and a second sheet including a second major surface of the warming blanket. The second sheet is sealingly joined to the first sheet to form one or more inflatable portions between the first and second sheets. An adhesive layer is disposed on the first major surface of the first sheet. A liner assembly is disposed on the adhesive layer opposite to the first major surface and fully covers the adhesive layer. The liner assembly includes a plurality of release liners delimited from each other and releasably bonded to the adhesive layer, such that each release liner is independently removable from the liner assembly to expose a corresponding portion of the adhesive layer. Each of the first sheet, the adhesive layer, and the plurality of release liners is air-permeable.
