South Tees Hospitals NHS Foundation Trust Barometry App

The Baromery 2 (version 2.4) web app developed by Clinical Measurement in the Medical Physics Department at The James Cook University Hospital, replaces Barometry Version 1. Barometry 2 includes the ability to read the pressure from a Druck Pace 1001 directly over ethernet.

This readme is mainly only useful for staff at south tees. For an example of how to connect to a Druck Pace 1001 Barometer via ethernet in C#, click here.

What's New?

• A full re-design of the look and feel of the app, which utilise the NHS Digital Design Library.
• Complete re-write of the code in C# MVC .Net .
• Better webscraping of Barometer 1 (Medical Physics Department Barometer) using the htmlagilitypack.
• Ivi.Visa library interface with the new Druck Pace 1001 barometer for reading VX11.
• In-built change log.
• Display of calibration dates.

Key Technical Information

This section identifies some of the important technical information for Barometry 2.

Barometer 1 - Medical Physics Department

The app web scrapes the HTML from Barometer 1 by using the HtmlAgilityPack. Specifically, it reads the HTML div tags ‘pres_mbar’ and ‘pres_mmhg’ and populates the data into a view.

Barometer 2 - The Endeavour Unit

The web app utilises Ivi.Visa to connect to the Druck Pace 1001 via VXI-11 by using a Visa session TCPIP::10.115.46.84::inst0::INSTR. It then sends the command :SENSe:PRESsure? to the Druck Pace 1001 and receives the mBar payload.

Currently, the mBar is converted into mmHg by using mBar * 0.750061561306.
