First Responder, Portable Neurodiagnostic Device

The primary challenge was miniaturizing the technology to ensure both functionality and portability. This process involved overcoming technical, ergonomic, and usability constraints while ensuring the device did not compromise paramedics' workflow in their daily operations or sacrifice aesthetic and functional value. Key considerations included the environment and user cohorts in which the device would be used and regulatory requirements for road and air ambulances. Balancing these factors while maintaining diagnostic accuracy and compliance with medical standards was critical to the device’s development.

The design team focused on integrating user needs and technical performance while maintaining a strong emphasis on size, weight, and access for users and patients, meeting paramedics' and clinicians' workflow demands during callouts and treatment. Miniaturization of core modules (proprietary antenna and signal analysis) and an integrated fluidics system were key. User observations, journey mapping, and challenges like developing a flexible cap for diverse head sizes and avoiding wrinkles during liquid filling, along with keeping the device under 14 kilograms, led to a balanced, portable, and accurate diagnostic solution.

Stroke has a devastating economic impact, both direct and indirect. Significant savings for health systems can be achieved by bringing neurodiagnostic tools to the patient rather than waiting for hospital arrival. The EMVision First Responder allows paramedics to scan patients on-site, identify and characterize strokes, and communicate results to neurologists via telehealth. Unlike costly Mobile Stroke Units (A$1.7M and specialist crews), the EMVision device costs around A$90K and is operated by trained personnel. Its cost per DALY averted is A$5,000, compared to A$30,982 for MSUs.

The First Responder device incorporates several innovative design features that ensure optimal performance in high-pressure emergency situations. Its compact, portable structure enables rapid deployment and seamless integration into existing paramedic workflows. A proprietary AI engine analyzes signals acquired by the EMVision First Responder, which, via the GUI and telehealth connectivity, presents real-time analysis of the patient’s brain to show whether they have a stroke, its type, and location. That information supports specialists' and paramedics’ decision-making. The device integrates seamlessly with telehealth networks for remote-assisted diagnostics, especially in underserved or remote areas. Key design considerations include its ergonomic form for easy handling in ambulances and outdoor environments, with durable materials selected for impact resistance and easy cleaning. The device's low weight, at just 14 kilograms, enhances mobility, and the flexible coupling cap accommodates a wide range of head sizes. Designed to meet both technical and regulatory requirements, the First Responder is a cost-effective alternative to Mobile Stroke Units, providing a scalable solution and integration with telehealth networks. The EMVision First Responder is positioned to transform pre-hospital care, filling a critical gap in stroke and TBI diagnostics.
