Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In clinical settings, such as intensive care units, medical devices are frequently connected and disconnected, leading to improper configuration and setup due to the lack of efficient interface systems that can adapt to various devices with or without plug-and-play capabilities.
Innovation Solution
A medical device interface system with a plug-and-play detector and serial agent that automatically detects medical devices, gathers information, selects appropriate device drivers, and enables communication between medical devices and clinical information systems, regardless of the device's plug-and-play capabilities, using a universal serial bus (USB) serial converter to facilitate dynamic and adaptive connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration and setup is required for each medical device, then device compatibility and control can be achieved, but clinician workload increases and configuration errors occur frequently
Solution Approach 1:
The system enables self-service through automatic device detection and configuration. The interface system automatically detects when a medical device is connected, retrieves device information, selects appropriate drivers, and configures communication parameters without requiring manual clinician intervention. This self-configuring capability resolves the contradiction by making device connection effortless while eliminating configuration time loss.
Solution Approach 2:
The system performs preliminary actions by pre-loading device drivers and communication protocols into the interface system. When a device connects, the system has already prepared the necessary software components and can immediately match them to the detected device type. This preliminary preparation eliminates the need for manual configuration during critical care moments.
2Adaptability or versatility
If a universal interface system is implemented to support multiple device types, then adaptability improves, but system complexity increases
Solution Approach 1:
The interface system implements universality by designing a single platform that can connect to and configure multiple types of medical devices through a common set of drivers and protocols. The system maintains a library of device-specific drivers that can be automatically selected based on the connected device type, providing multi-functionality without requiring separate dedicated interfaces for each device category.
Solution Approach 2:
The interface system acts as an intermediary layer between the clinical information system and various medical devices. This mediator contains the complexity of device-specific communications within itself, translating diverse device protocols into a unified interface. The intermediary approach allows the upper-level system to remain simple while handling device diversity at the interface level.
3Productivity
If automatic device detection is implemented, then setup time is reduced, but reliability of device identification may be compromised
Solution Approach 1:
The system implements feedback mechanisms where the automatic device detection process continuously verifies device identification. After initially detecting a device and selecting a driver, the system tests the communication connection and validates that the device responds correctly. If identification is incorrect, the feedback loop triggers re-detection and re-configuration, ensuring reliable device identification while maintaining rapid setup through automation.

AI summary
Certain examples provide systems, apparatus, and methods for adaptive, dynamic medical device connectivity. In an example, a medical device interface system includes a device interface connecting a medical device to a client system and enabling exchange of data between the medical device and the client system, the device interface includes a plug and play detector detecting a connection of the medical device to the device interface and a serial agent gathering information from the medical device via a connection between the medical device and the device interface and selecting an appropriate device driver to operate and interact with the medical device connected to the device interface regardless of a presence or absence of an existing plug and play capability of the medical device.
