Remote Healthcare Device Diagnostics via Protocol Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare devices, such as patient support systems, often require preventative or responsive service or replacement based on monitored data, but this information is typically only accessible locally and not remotely, leading to potential failures before diagnostic insights can be acted upon.
Innovation Solution
A remote diagnostic monitoring system that includes a sensor system generating data on patient support system parameters, a communication adapter for protocol conversion, and a monitoring device geographically distant, capable of determining diagnostic status and initiating service or replacement orders via telecommunication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diagnostic information is made accessible remotely, then maintenance efficiency and reliability are improved, but device complexity and communication infrastructure requirements increase
Solution Approach 1:
A communication adapter is introduced as an intermediary device between the sensor system and remote monitoring systems. This adapter handles protocol conversion and data transmission, isolating the complexity from both the sensor system and remote endpoints. The adapter translates internal device protocols into standard communication protocols (XML, TCP/IP), enabling remote access without complicating the core device architecture.
Solution Approach 2:
The system is divided into distinct functional modules: sensor systems for data collection, communication adapters for protocol conversion and transmission, and remote monitoring devices for analysis. This segmentation allows each component to be optimized independently and simplifies the integration of remote monitoring capabilities into existing healthcare devices.
2Measurement precision
If sensor data is transmitted continuously for remote monitoring, then diagnostic accuracy is improved, but data transmission volume and network bandwidth requirements increase
Solution Approach 1:
The communication adapter extracts and transmits only the essential diagnostic parameters and status information needed for remote monitoring. Rather than transmitting all raw sensor data continuously, the system identifies and transmits key metrics (temperature, pressure, operational status, error codes) that are sufficient for diagnostic purposes, reducing overall data volume while maintaining diagnostic accuracy.
Solution Approach 2:
The system transmits data at selective intervals and only when changes occur, rather than continuous transmission. This partial action approach ensures critical diagnostic information is captured without the overhead of constant data streaming, optimizing the balance between monitoring accuracy and network resource consumption.
Data Source
AI summary
A method and system for remote diagnostic monitoring of a healthcare device, for example, a patient support system. The system includes a communication device configured to transmit sensor data received from a sensor system coupled to the patient support system and configured to generate sensor data relating to diagnostic information of the healthcare device. The communication device can also be configured to receive configuration data for configuring at least one of the healthcare device and the sensor system. The monitoring device is located geographically distant from the healthcare device, is coupled to the communication adapter by a datalink, for example, a telecommunication network, and is configured to receive the sensor data. The monitoring device is configured to determine, based on the received data, whether service or replacement of the healthcare device or a portion thereof is indicated.
