DEXTMEDI User Manual

1. Introduction

DEXTMEDI is a Solution that collects data transmitted from various medical devices and converts it into a standardized format. This document serves as a guide for using DEXTMEDI. It explains how to install the software and provides instructions for the basic settings required to collect data from medical devices. It introduces methods for utilizing the collected data and integrating the solution with external systems.

2. Screen Layout

The interface of DEXTMEDI is primarily composed of two main screens. The GATE screen, where integration modules are configured, and the LOG screen, which displays logs. The GATE main screen displays the operational status of currently integrated modules, actual operations can be configured through the settings screen of each integrated module. Users can switch between screens using the tabs at the top. and you can perform batch operations on registered modules or change DEXTMEDI’s default settings.

8. Settings by Parsing Method

These are the settings to configure how the collected data is parsed.

1) Script Parser

This option is available when the collected data is in XML format. Most ECG data falls into this category. Data is converted using an XSLT script, and a basic conversion script is installed along with the product. You can modify this script to process the data into your desired format.

[Image 18] XML Transformation Engine Schema Panel

A. Script : Configure the XSLT script for conversion. By default, the script provided by DEXTMEDI is automatically selected. If modifications are required, you may directly edit and use a custom XSLT script.

2) Name Parser

In the case of file polling, you can extract metadata using the file name. This method can be used when can be distinguished through delimiters within the file name.

[Image 19] String Token Index Extractor Setup

A. Delimeter : Set the delimiter.
B. Item Set the metadata item. If the value is extracted correctly the extracted information will be used as each item when generating XML. In the numeric field on the right, enter the index (starting from 0) where the item is located when separated by the delimiter.
