Rotatable Panel Resuscitator Shield for Fluid Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield devices do not effectively protect caregivers from bodily fluids during CPR, as they fail to prevent fluid contact between the patient and the caregiver.
Innovation Solution
A resuscitation bag with a hose and a rotatably coupled panel that positions between the patient's face and the caregiver, inhibiting fluid contact by blocking expelled bodily fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional resuscitation setup is used without a shield, then the device complexity is low and ease of operation is high, but the caregiver is exposed to bodily fluids during CPR
Solution Approach 1:
The patent introduces a panel as an intermediary barrier between the patient's face and the caregiver. This panel is rotatably coupled to the coupler and can be positioned to block bodily fluids from reaching the caregiver while allowing the resuscitation procedure to continue. The panel acts as a mediator that protects the caregiver without interfering with the CPR process.
Solution Approach 2:
The panel is designed to be rotatably coupled to the coupler rather than being fixed, allowing it to be dynamically adjusted and positioned as needed. This dynamic configuration enables the panel to be moved into position to block fluids and then rotated out of the way when not needed, maintaining flexibility in the resuscitation process while providing protection when required.
2Object-affected harmful factors
If a fixed shield is used to block bodily fluids, then protection is provided, but the ease of operation decreases due to restricted movement and positioning
Solution Approach 1:
The panel's rotational coupling to the coupler allows it to be dynamically positioned. It can be rotated into place to block fluids and then rotated away when not needed, providing protection without permanently obstructing the resuscitation area. This dynamic adjustment maintains ease of operation while providing fluid barriers when required.
Solution Approach 2:
The shield assembly is segmented into separate components: the coupler that attaches to the resuscitation bag and the panel that rotates from the coupler. This segmentation allows the panel to be independently positioned and adjusted without affecting the attachment of the resuscitation bag, maintaining operational flexibility while providing fluid protection.
3Object-affected harmful factors
If a rotatably coupled panel is added to the resuscitator, then bodily fluid protection is improved, but the device complexity increases
Solution Approach 1:
The assembly is divided into modular components: a coupler that attaches to the resuscitation bag and a separately rotatable panel. This segmentation allows the complex protective function to be added as a distinct module rather than integrating it into the basic resuscitation device, making the complexity manageable and the protective function independently adjustable.
Solution Approach 2:
The coupler serves multiple functions: it attaches the resuscitation bag and simultaneously provides the mounting structure for the rotatable panel. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while still providing the fluid protection capability.

AI summary
A resuscitator mouth shield assembly for protecting a caregiver from bodily fluids during CPR includes a resuscitation bag that has a hose extending toward a face cup. A coupler releasably engages the resuscitation bag and a panel is rotatably coupled to the coupler. The panel is spaced from the resuscitation bag when the coupler is positioned on the resuscitation bag. Moreover, the panel is positioned between a patient's face and a caregiver when the resuscitation bag is positioned on the user's face. In this way the panel inhibits bodily fluids that are expelled from the patient from contacting the caregiver.
