Wound Therapy Communications Controller Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current negative pressure wound therapy systems face communication delays and errors due to reliance on a single main controller for communication between electronic devices and other controllers, which can interrupt therapy and complicate testing and troubleshooting.
Innovation Solution
The system includes a separate communications controller that can directly communicate with electronic devices via wired or wireless communication, allowing executable commands to be executed without relying on the main controller, enabling independent operation and facilitating faster testing and troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single main controller is used for communication between electronic devices and other controllers, then the system structure is simplified, but communication delays and errors increase
Solution Approach 1:
The patent divides the communication control function into two separate controllers: a main controller for therapy control and a communications controller for communication operations. This segmentation allows each controller to specialize in its function, reducing communication delays and errors while maintaining system reliability.
2Device complexity
If all commands must be processed by the main controller, then centralized control is maintained, but therapy interruption occurs during communication operations
Solution Approach 1:
The patent separates command processing responsibilities between the main controller and communications controller. The communications controller can execute communication commands independently without requiring main controller intervention, allowing therapy to continue uninterrupted during communication operations.
3Device complexity
If a single controller handles all operations, then device complexity is reduced, but testing and troubleshooting become more difficult
Solution Approach 1:
The patent implements separate controller assemblies that can be independently tested and troubleshooted. The communications controller assembly can be tested independently of the main controller, simplifying diagnostic procedures and repair operations.
4Device complexity
If communication operations are handled by the main controller, then system coordination is simplified, but communication delays increase
Solution Approach 1:
The patent assigns communication operations to a dedicated communications controller that operates independently from the main controller. This eliminates the time required for the main controller to process communication commands, significantly reducing communication delays.

AI summary
Embodiments of negative pressure wound therapy systems and methods are disclosed. In some embodiments, a wound therapy system includes a negative pressure source configured to provide negative pressure via a fluid flow path to a wound dressing, a first circuit board assembly including a first controller configured to control a wound therapy with the wound dressing by activation and deactivation of the negative pressure source, and a second circuit board assembly in communication with the first circuit board assembly, the second circuit board assembly separate from the first circuit board assembly. The second circuit board assembly can include a second controller configured to wirelessly communicate therapy data via a communication network, receive an executable command from an electronic device, and execute the executable command without providing the executable command to the first controller.
