Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices often lack modern data exchange capabilities and security measures, limiting their integration into hospital networks and the internet, and are vulnerable to cyberattacks.
Innovation Solution
An interface device with integrated circuits and secure interfaces that facilitate data exchange between medical devices and remote devices via networks, ensuring data integrity and security by using software-controlled updates that do not affect existing data transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medical devices use restricted data exchange interfaces (e.g., serial interfaces), then device complexity is reduced, but adaptability to modern network standards deteriorates
Solution Approach 1:
The patent introduces an interface device as an intermediary component that bridges medical devices with modern network standards. This mediator device handles the complexity of network protocols and data format conversions, allowing medical devices to maintain simple serial interfaces while gaining connectivity to hospital networks and the internet through the interface device's sophisticated communication capabilities.
2Adaptability or versatility
If software updates are enabled for interface devices, then adaptability and security improve, but data integrity and security risk worsen
Solution Approach 1:
The patent segments the interface device into distinct functional zones: a first interface zone for secure data reception from medical devices, a second interface zone for network communication, and a processor zone for software execution. This segmentation isolates the software update mechanism to specific areas while protecting the data transfer paths, allowing software to be updated without compromising the integrity of data exchanged with medical devices.
Solution Approach 2:
The processor acts as an intermediary that manages software updates separately from data transfer operations. It receives update instructions, validates them against security criteria, and applies updates only when safe, thereby mediating between the need for software improvement and the need to maintain secure data transfer.
3Reliability
If interface devices are secured to prevent software influence on data transfers, then data security improves, but ease of operation deteriorates
Solution Approach 1:
The interface device implements self-service security mechanisms where the processor automatically receives security criteria, evaluates potential software updates against these criteria, and decides whether to apply updates without human intervention. This automated self-service approach maintains high security standards while simplifying the operation for users, as they simply need to connect to the network without managing complex security settings.

AI summary
An interface device for data exchange of medical devices with remote devices via networks ensures that the data transfer from the medical device to the interface device can be read out reliably and that the data exchange with the at least one remote device is robust with respect to undesired data exchange. The medical devices may include, for example, hemodialysis (HD) or peritoneal dialysis (PD) treatment devices.
