Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems lack bidirectional communication capabilities, limiting their ability to receive and respond to data from remote sources for controlling ventilator settings and patient care adjustments.
Innovation Solution
A ventilation management system that enables two-way communication between ventilators and a management system, allowing for the exchange of patient data, configuration profiles, and clinical protocols, and the ability to modify operating parameters based on received data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If common ventilation systems are configured to provide information for display only, then the system complexity is reduced and ease of operation is improved, but the adaptability and ability to receive remote control data is limited
Solution Approach 1:
The ventilation system incorporates bidirectional communication capabilities that allow it to not only display information but also receive and process data from remote sources. The system can receive patient data, order data, configuration data, user data, and rules/protocols over a network, enabling feedback loops that improve adaptability while maintaining manageable complexity through structured data processing architecture.
2Adaptability or versatility
If the ventilation system receives and processes multiple types of data from remote sources, then the adaptability and patient care quality improve, but the device complexity and data processing requirements increase
Solution Approach 1:
The system segments data processing by receiving different types of data (patient data, order data, configuration data, user data, rules/protocols) through structured communication protocols. Each data type is processed according to its specific requirements, with the processor configured to handle each category systematically, reducing overall processing complexity while maintaining comprehensive data reception capabilities.
Solution Approach 2:
The communication module acts as an intermediary between remote data sources and the ventilation device's processing systems. It manages the reception, validation, and routing of various data types, shielding the internal processing architecture from the complexity of external data interfaces and enabling adaptable data integration without proportionally increasing internal system complexity.
3Productivity
If real-time data exchange is enabled between ventilator and management system, then the productivity and patient care quality improve, but the energy consumption and network requirements increase
Solution Approach 1:
The system implements periodic data exchange mechanisms where the ventilation device communicates with the management system at scheduled intervals rather than continuously. This allows real-time adjustments to be made when needed while reducing energy consumption by maintaining communication only during necessary periods, balancing productivity improvements with energy efficiency.
Data Source
AI summary
A ventilation management system communicatively couples a remote device such as a mobile device to one or more ventilators for monitoring of ventilator data, including ventilator configuration data, patient physiological statistics, and notifications. When a command to modify a configuration parameter of the ventilator is received while the ventilator is unavailable for communication, the command is cached and provided when the ventilator becomes available. When ventilator becomes available, the system receives an indication that the configuration parameter was modified at the ventilator, an operating condition of the ventilator, and a physiological statistic of a patient associated with the ventilator, the operating condition and physiological statistic having been cached by the ventilator while the ventilator is unavailable. The operating condition of the ventilator, the physiological statistic of the patient, and the indication that the configuration parameter was modified is provided to the remote computing device for display.
