Peritoneal Dialysis Machine USB Interface Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peritoneal dialysis machines lack efficient data communication capabilities, making it difficult for patients and healthcare providers to manage and monitor treatment data, patient profiles, and prescription changes, which hinders the convenience and effectiveness of home-based dialysis therapy.
Innovation Solution
A peritoneal dialysis machine equipped with a USB data communications interface, including a USB port and a USB interface control system, allows for the uploading and downloading of treatment data, patient profiles, and the playback of training videos using a USB flash drive and built-in media player.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a peritoneal dialysis machine is equipped with data communication capabilities, then data management and monitoring convenience is improved, but device complexity increases
Solution Approach 1:
The USB interface control system serves multiple functions: transferring patient profile data, treatment prescription data, treatment delivery data, and training video data. This multi-functional approach improves data management convenience while avoiding the need for separate communication interfaces for each data type, thereby limiting the increase in device complexity.
Solution Approach 2:
A USB flash drive acts as an intermediary storage device between the peritoneal dialysis machine and external systems. The machine communicates data to and from the flash drive, which then serves as a portable repository that can be easily transferred to other systems for further processing or storage, simplifying the machine's communication requirements.
2Loss of information
If treatment data is stored locally in the machine, then data availability is improved, but loss of information risk increases
Solution Approach 1:
The system creates copies of treatment data, patient profiles, and prescriptions by transferring them to a USB flash drive. This copying mechanism ensures that data exists in multiple locations (both in the machine and on the portable drive), preventing information loss if one storage medium fails, while maintaining data availability through easy access to copies.
Solution Approach 2:
The system performs preliminary data backup by transferring treatment data to the USB flash drive during or after treatment cycles. This preliminary action of creating external copies before potential data loss scenarios ensures data preservation and maintains reliability while keeping data readily accessible.
