The Biomedical Equipment Technician (BMET) Library is a digital library containing resources for BMETs working in the developing world. Our open-source collection provides information about repair and preventative maintenance of medical devices, healthcare technology management, Biomedical Equipment Technician’s Assistant skills, as well as resources on a variety of topics like mathematics, electronics, physiology and more!
Created by Engineering World Health (EWH) and Robert Malkin’s Developing World Healthcare Technologies Laboratory, the BMET Library supports EWH’s expanding BMET Training Program in Rwanda, Honduras, Ghana, Cambodia, and Nigeria. The goal of our library is to make useful resources available to technicians practicing in the clinical environment, as well as to instructors and students in the biomedical field.

How to search the BMET Library
This collection contains open source educational materials useful for biomedical equipment technicians (BMETs). How to find information in the library:
1. Search Box:
Use the Search option to enter keywords. You can search based on words that appear in the titles of a document or within the text of a document. The preferences page (located in the upper right corner) allows you to conduct an advanced search.
Three ways to search:

B. "Subjects" This allows you to search all of the subjects and topics on this website.
C. "Search All Fields" This allows you to search for author, publisher, source, and subject all at once
The Topics option can be used to browse list of topics included in this library such as: Anatomy and Physiology, the Biomedical Technician Assistant (BTA) skills, Electronics, Healthcare Technology Management (HTM), Mathematics, and Medical Equipment. These lists contain all information we have available on a topic...
3. Books and Publications
The Books and Publications by Chapter option can be used to browse individual chapters of a book. Each book is divided into various “chapters," each addressing a particular topic within the library.
4. Complete Books:
If you have a fast internet connection you can view and download each book in its entirety using the Complete Books option above.
For information regarding copyright and use of documents in the digital library see our Copyright and Use Guide.
How to Read Files
- Opens a html version of the chapter in the same tab. This option will be the fastest if bandwidth is an issue. Does not include pictures, diagrams, and rich text elements.
- Opens a pdf version in your browser that preserves all pictures and diagrams. To save a document for offline use, open as a pdf and then save the document.
Copyright and Use Information
This website is currently only available in English, if you need to access the website or its resources in another language Google Translate Google Translate (https://translate.google.com/) is very useful. Google Translate will allow you to type in text to translate, upload a document to be translated, or enter a web address and translate the entire site. Just like with most online translation services Google Translate is not perfect and also works better with small pieces of text. If a translation does not make sense translating a smaller phrase may help resolve the issue.
For the purposes of using this site, Google Translate is able to translate the page and allow you to navigate the translated page. However one must be careful when using Google Translate with PDF files, it can only handle files up to 1 MB, larger files must be split (http://www.splitpdf.com/). Additionally even if a PDF document is not over 1 MB translating it may scramble the content or remove the images.
Google Translate can translate HTML files too, and often it does not scramble the content like it does with PDFs, however HTML files do have some drawbacks. These types of files do not have the images or text formatting that the PDF files of the same resource may have.
The search function of the website currently only supports searches in English. If you need to search in a different language then go to Google Translate, select your language on the left and English on the right, then enter your desired search phrase and click translate. After translating the phrase copy it and then paste it back into the search bar, select your search preferences, and click “Begin Search”. It is especially important when searching by this method to use very short and simple phrases, the shorter the phrase the more likely it is translated correctly and will lead to the correct information.
Translation Step-by-Step Walkthrough:
- If you are using Google Chrome it can be configured to automatically offer to translate pages that are in different languages. This is done by going to advanced settings and checking the box labeled “Offer to translate pages that aren’t in a language you read”.
- If the previous step does not work or you are using a browser other than Google Chrome go to https://translate.google.com/ to open Google Translate
- Select English on the left and the desired language on the right
- In order to translate the main page copy the following link (http://library.ewh.org/greenstone/cgi-bin/library.cgi?site=localhost&a=p&p=about&c=osrc0122&l=en&w=utf-8) and paste it into Google Translate, for a specific page copy that link and paste it into the translator.
- In order to translate a file download it from the site and then return to https://translate.google.com/, click “translate a document” just below the textbox, then click choose file and select the document you have just downloaded. Alternatively if you are using the translated version of the site on Google Chrome when you click the link to download a resource it will automatically ask you if you want to have the file translated before you open it. It is important to remember that Google Translate will only accept files less than 1 MB and the translation may affect the readability of a PDF file.
This digital library is powered using Greenstone, an open source software for creating digital libraries. More information about how to use this library and execute searches with the MGPP search engine can be found on the "Help" page via the link above.
Contents of the Website
This digital library contains open source information from six major areas, Anatomy and Physiology, Biomedical Technician’s Assistant (BTA) Skills, Electronics, Healthcare Technology Management (HTM), Mathematics, and Medical Equipment.
The Anatomy and Physiology section can be used to learn more about the parts, systems, and functions of the human body and is broken down into chapters by the various organ systems in the human body.
The BTA Skills are a series of short articles developed by Robert Malkin’s Developing World Healthcare Technology (DHT) Laboratory at Duke University. Overall there are 113 of these skills and they cover five basic areas, Electrical Skills, Mechanical Skills, Motors Skills, Plumbing Skills, and Power Supply Skills.
The documents relating to Electronics cover the basics of electrical current and circuitry and the care and safe use of electrical equipment. This section contains a full textbook on electric circuits and articles that go over how to properly maintain and safely use electrical equipment; including batteries, electrodes, motors, power supplies, plugs, and sockets.
The Healthcare Technologies Management (HTM) section covers how to effectively manage a healthcare facility (hospital, clinic, or laboratory). It has a series of documents that give an overview of how to acquire, organize, operate, and maintain medical equipment. There are additional documents that cover finances and some basic hospital procedures such as sterilization.
The Mathematics section contains four documents covering algebra, trigonometry, geometry, and statistics and probability.
The Medical Equipment section has resources that provide information on specific pieces of medical equipment and for each piece of equipment that is included there is information on how the equipment is used, the principles behind its operation, how to maintain the equipment in safe working condition, and how to fix some common problems with the equipment.
