Proning Face Pack With Moisture Vapor Removal Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an improved face support pack that controls moisture and friction-induced skin breakdown during prone therapy.
Innovation Solution
A proning head pack with a facial interface layer that is liquid vapor permeable but liquid and air impermeable, a boundary layer that is air impermeable, and a spacer layer configured for air flow, designed to expose the eyes, mouth, and nose, with a moisture vapor removal layer to transmit moisture vapor away from the patient's face while supporting the patient with fluid pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional face support pack is used during prone therapy, then the patient receives support, but moisture accumulates causing skin breakdown
Solution Approach 1:
The face pack is divided into multiple functional layers: a moisture-wicking layer to absorb and transport moisture away from the face, a spacer layer to maintain air circulation and prevent direct contact between moisture and skin, and a support layer to provide structural support. This segmentation allows each layer to address specific aspects of moisture management and skin protection independently.
Solution Approach 2:
The spacer layer acts as an intermediary between the moisture-wicking layer and the patient's face, creating a physical barrier that prevents direct contact between accumulated moisture and the skin. This intermediary layer facilitates air circulation while protecting the skin from harmful moisture effects.
2Object-affected harmful factors
If the face pack seals completely to prevent moisture ingress, then moisture control improves, but air flow is blocked causing discomfort
Solution Approach 1:
Different regions of the face pack have different permeability characteristics. The boundary layer is air impermeable to prevent moisture ingress, while the spacer layer contains air-permeable regions that allow controlled air circulation. This local differentiation of properties enables simultaneous moisture control and air flow where needed.
Solution Approach 2:
The face pack utilizes composite material construction with layers having different permeability properties. The combination of moisture-wicking materials, air-permeable spacer materials, and air-impermeable boundary materials creates a composite structure that achieves both moisture control and selective air flow functionality.

If fluid pressure is applied to provide support, then patient support improves, but pressure loss compromises support effectiveness
Solution Approach 1:
The support layer is designed to provide baseline support even before fluid pressure is applied, and continues to provide support if pressure is lost. This redundant support mechanism ensures that patient safety is maintained regardless of pressure system failures, providing beforehand cushioning against support loss.
Solution Approach 2:
The face pack system allows for dynamic adjustment of fluid pressure parameters to optimize support levels. The boundary layer can be adjusted to be substantially impermeable to water vapor when high support is needed, while the spacer layer maintains air permeability for comfort, enabling parameter changes to balance support and comfort requirements.
