Web-Based Medical Instrument Management via Intranet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems for point-of-care medical instruments are limited by their reliance on wired connections and are not adaptable to different connectivity scenarios, restricting user access and management to physical locations and requiring device-specific applications, which increases development costs and user experience variability.
Innovation Solution
A web-based data and instrument management system that allows users to manage patient and instrument data through a handheld or mobile wireless device with a web browser, providing a common user experience across devices and secure access within a hospital's intranet range, using a web server hosted on an intranet network that communicates with user devices and medical instruments via a secure intranet connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired connections and physical location-based data management are used, then system security and data integrity are maintained, but user accessibility and operational flexibility are restricted
Solution Approach 1:
A web server acts as an intermediary between the wireless user interface and the medical instrument. The server receives requests from wireless devices, processes them securely, and communicates with the instrument through established wired connections. This mediator architecture enables wireless accessibility while preserving the security and reliability of the core data management system.
Solution Approach 2:
The system is divided into distinct functional modules: a wireless user interface layer for accessibility, a web server layer for security and protocol handling, and the core instrument layer for data integrity. This segmentation allows each layer to be optimized independently - the wireless interface provides flexibility while the core instrument layer maintains strict data integrity controls.
2Adaptability or versatility
If device-specific applications are developed for each handheld device, then device functionality is optimized, but development costs and system complexity increase
Solution Approach 1:
The system implements a universal web-based interface that runs on any wireless device with a web browser. Instead of creating separate applications for different device types, a single HTML-based interface provides consistent functionality across smartphones, tablets, and other wireless devices. This universal approach reduces development complexity while maintaining broad device compatibility.
3Reliability
If wired computers with installed software are used, then data management functionality is provided, but physical location constraints and hardware requirements are imposed
Solution Approach 1:
The system replaces the mechanical requirement of physical computer workstations with wireless electronic devices. Instead of requiring users to be at fixed desks with installed software, the interface is delivered through wireless communication using standard web browser technology. This substitution maintains data management capability while providing mobility and connectivity flexibility.

AI summary
A data and instrument management and interface system comprises a web server hosted on an intranet network having a wireless range. The web server has a processor, and a non-transitory computer memory coupled with the processor and storing processor executable code. The web server can communicate over the intranet network with a web browser running on a handheld user device located within the wireless range of the intranet network, and with an instrument. The processor executable code causes the processor to: receive a first wireless signal over the intranet network, the first wireless signal transmitted by the web browser and indicative of request for data for the instrument; authenticate the handheld user device and a user of the web browser; and transmit a second wireless signal to the web browser indicative of data for the instrument responsive to the handheld user device and the user being authenticated.
