Prehospital Mobile Telemedicine Videoconference for Stroke Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and treating stroke patients in ambulances are plagued by delays and lack accuracy, especially in rural areas, due to limited diagnostic capabilities during transit, leading to potential worsening of the patient's condition.
Innovation Solution
Implementing a prehospital mobile telemedicine videoconference system that enables real-time evaluation of stroke symptoms via videoconference between ambulance personnel and qualified clinicians, using mobile devices connected via cellular networks, allowing for secure transmission of patient information and potential initiation of medical alerts before the patient reaches the hospital.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional ambulance transport methods are used, then the patient can be transported to the hospital, but the diagnosis and treatment time is delayed due to limited diagnostic capabilities during transit
Solution Approach 1:
The patent extends the diagnostic process from the hospital dimension to the ambulance transport dimension by enabling videoconferencing during transit. This allows stroke assessment to occur in the previously inaccessible dimension of prehospital transport, transforming wasted transit time into productive diagnostic time without adding complex equipment to the ambulance itself.
Solution Approach 2:
The patent introduces a videoconferencing system as an intermediary between the ambulance and the hospital stroke team. This intermediary enables real-time communication and diagnostic evaluation during transport, allowing the hospital team to assess the patient remotely without requiring the ambulance to be equipped with full diagnostic capabilities.
2Measurement precision
If advanced diagnostic equipment is installed in ambulances, then stroke recognition accuracy can be improved, but the cost becomes prohibitively high especially for rural areas
Solution Approach 1:
The patent uses videoconferencing technology to create a visual copy of the patient and their symptoms that can be transmitted to the hospital for assessment. Instead of transporting expensive diagnostic equipment to the ambulance, the system captures visual information (the 'copy' of the patient's condition) and transmits it remotely, achieving accurate stroke recognition at low cost.
Solution Approach 2:
The patent leverages the universal applicability of videoconferencing technology, which can be implemented in any ambulance regardless of location or budget. This multi-functional approach allows the same low-cost videoconferencing system to serve both communication and diagnostic functions, making advanced stroke assessment accessible to rural areas without requiring specialized expensive equipment.
3Productivity
If comprehensive stroke assessment is performed during ambulance transit, then treatment can commence sooner, but the complexity of conducting assessment during movement increases
Solution Approach 1:
The patent extracts the complex diagnostic assessment function from the ambulance environment and relocates it to the hospital environment. By taking out the assessment complexity from the moving ambulance and performing it remotely at the stationary hospital, the system enables comprehensive stroke evaluation during transit without actually increasing the complexity within the ambulance itself.

AI summary
A method for facilitating mobile telemedicine for a suspected stroke case can include initiating, with an evaluation device, a prehospital mobile telemedicine videoconference with a remote device when a projected amount of time exceeds a threshold. The method can include determining for presentation, a set of specified symptoms of a stroke, the specified symptoms obtained remotely using the prehospital mobile telemedicine videoconference, obtaining input from a user, including information indicative as to whether a patient is exhibiting symptoms of a stroke, and in response to obtaining input, transmitting, from the evaluation device to the remote device, the information indicative as to whether the patient is exhibiting symptoms of a stroke. The method can include generating a medical alert, at the evaluation device, the medical alert including patient information and the information indicative as to whether the patient is exhibiting symptoms of a stroke.
