Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home treatment of chronic ailments like renal failure poses risks due to the absence of trained staff, necessitating creative solutions to ensure that medical devices are used safely and only under proper supervision.
Innovation Solution
A home treatment system that authenticates authorized personnel using biometric indicators and continuously monitors their presence through video classification, ensuring that a trained assistant is present during treatment by implementing warning procedures and failsafe modes if the assistant is not available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If home treatment is provided without trained staff present, then patient convenience and accessibility are improved, but safety and reliability deteriorate due to potential adverse reactions and misuse
Solution Approach 1:
The system enables patients to perform treatments independently at home through automated authentication and monitoring features. The device can verify the patient's identity, check for the presence of authorized assistants, and automatically adjust treatment parameters without requiring constant human intervention, thus maintaining safety while improving convenience
Solution Approach 2:
The system continuously monitors treatment conditions and provides real-time feedback through multiple mechanisms. Sensors detect patient vital signs and device operational status, while communication systems provide feedback to remote healthcare providers. This closed-loop feedback ensures safety constraints are maintained even when trained staff are not physically present
2Reliability
If authentication and monitoring systems are implemented, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single unified platform. The authentication module handles both patient and assistant verification, the monitoring system tracks both device operational status and patient vital signs, and the communication interface serves multiple purposes including alerts, data transmission, and remote supervision. This multi-functionality reduces overall system complexity despite the comprehensive safety features
Solution Approach 2:
The patent combines authentication, monitoring, communication, and control functions into an integrated system architecture. Rather than separate independent systems, these functions are merged into a cohesive unit where components share hardware resources and software protocols, reducing the overall complexity burden while maintaining comprehensive safety
3Reliability
If continuous monitoring of assistant presence is implemented, then safety is improved, but use of energy increases
Solution Approach 1:
The system employs periodic sampling rather than truly continuous monitoring. The assistant presence detection and treatment parameter verification occur at predetermined intervals during the treatment cycle. Communication with remote providers and system status checks are performed periodically, allowing the system to maintain safety while reducing energy consumption compared to constant real-time monitoring
Solution Approach 2:
The monitoring intensity dynamically adjusts based on treatment phase and risk level. During critical treatment phases or when adverse reactions are detected, monitoring frequency increases. During stable phases, monitoring intensity decreases. This dynamic adaptation optimizes energy usage while maintaining safety throughout the treatment process

AI summary
A medical treatment device is configured to be used during a treatment session at a first location and includes a medical treatment component configured to perform at least one of hemodialysis, hemofiltration, and peritoneal dialysis on a patient during the treatment session at the first location. The device also includes a monitoring system configured to receive data from one or more sensors connected to the monitoring system, and to confirm a presence of an authorized helper at the first location. A user interface permits an operator to control functions of the medical treatment component and the monitoring system is configured to perform the presence confirmation automatically and at the predefined time intervals during the treatment session. The monitoring system is also configured to generate an alarm and to cause the medical treatment component to go into a failsafe operational mode.
