Foam Head Protective Device for Supine Surgery Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During surgery, patients in a supine position are at risk of severe damage due to unintentional pressure on ocular structures and uneven pressure leading to decreased blood flow and potential nerve damage, as they cannot move to alleviate discomfort under general anesthesia.
Innovation Solution
A protective device comprising a face portion with apertures and flexible side portions made of foam, where the top layer is firmer and thicker than the base layer, designed to be wrapped around the head to direct forces away from sensitive areas, prevent head movement, and maintain blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective device is used to protect the face and head, then protection against pressure damage is improved, but the device may cause uneven pressure leading to decreased blood flow
Solution Approach 1:
The protective device incorporates a conformal design that adapts to the specific contours of the patient's face and head, creating locally optimized pressure distribution. The device includes adjustable positioning elements and contoured surfaces that match individual anatomical variations, ensuring uniform pressure application across different facial regions while maintaining protective coverage.
Solution Approach 2:
The device utilizes materials and structural design elements that can be adjusted to optimize pressure distribution parameters. This includes adjustable straps, modular components, and materials with specific pressure-distributing properties that can be tailored to the patient's anatomy, transforming the pressure profile from uneven to uniform while maintaining protective function.
2Productivity
If the patient is placed in supine position for surgery, then surgical access is improved, but the patient cannot move to alleviate discomfort from pressure on facial structures
Solution Approach 1:
The protective device is designed and positioned on the patient's face and head before the surgical procedure begins, establishing a protective barrier that prevents pressure damage throughout the entire surgery. The device includes pre-configured apertures for eyes, nose, and mouth, and is secured with adjustable elements that ensure proper positioning before the patient becomes fully anesthetized and immobile.
Solution Approach 2:
The device incorporates cushioning elements and pressure-distributing materials that are positioned in advance to protect vulnerable facial structures. These cushioning features are integrated into the protective device design, providing preemptive protection against pressure injuries to the eyes, nose, ears, cheeks, and mouth before any harmful pressure can occur during the prolonged supine surgical position.
3Reliability
If conventional protective methods are used, then some facial protection is provided, but the protection is insufficient against severe damage and blindness
Solution Approach 1:
The protective device serves multiple protective functions simultaneously: it shields the eyes, nose, ears, cheeks, and mouth from pressure damage; maintains proper head positioning; distributes pressure uniformly; and prevents facial nerve compression. This multi-functional design provides comprehensive protection that addresses all vulnerable facial structures in a single integrated device, significantly enhancing protection beyond conventional single-purpose methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively protects the patient's face and head by distributing forces away from sensitive areas, preventing injury and maintaining blood flow, thus providing increased protection compared to conventional methods.
Implementation Method 1
The top layer and base layer may be constructed of foam... the top layer may be constructed of a foam that is firmer or stiffer than the foam of the base layer

AI summary
A protective device for protecting the face and/or head of an individual receiving medical treatment in a face upward position includes a face portion having an exterior surface, an interior surface, and an aperture extending from the exterior surface to the interior surface, and includes a pair of opposed flexible side portions extending outwardly from the face portion. The face portion is configured to be positioned about the face of an individual with at least a portion of the individual's face exposed by the aperture, and the side portions are configured to be wrapped around and completely surround the head of the individual whereby the individual's head is supported on at least one of the side portions when the individual is receiving medical treatment in a face upward position.
