Now days locating and tracking equipment at
the hospitals is a major problem.
Hospital logistics became more complicated
during the last years through the progress of
medical science (i.e. biomedical engineering).
New and expensive equipment are purchased by
the hospitals, which need to be managed in an
efficient way.
Current hospital equipment management are
inefficient and require manual processes.
The situation of a nurse looking urgently for an
infusion pump or other medical device while a
multitude of those are lying “secretly” in a
neighboring section is a known picture.
Common used equipment is distributed
unevenly between various department with
different needs.
Hospital equipment theft \ Lost – awareness for
stolen hospital equipment is usually discovered
on critical times even though it could be
discovered earlier.
Labor costs - The hospital staff spends roughly
10% of shipment time looking for some sort of
critical equipment.
Time lost during medical procedures on
searching available equipment.
Increased inventory costs - purchase or rent
more equipment due to lack of availability caused by poor management tools.
Wrong Verification of a product - Use the wrong
equipment. (medicine etc).
High Equipment Wear due to unbalanced use.
i.e. one cart is traveling between rooms
numerous number of times, while other
available carts are laying unused.
Staff frustration with operational inefficiencies.
Loss - Of critical And\Or Expensive equipment.
In this era of severe budget constraints these
problems should receive increased attention
And implementation of efficient systems is
A System that will use the ScanTask mobile
solution of cellular bar-code readers to
accomplish an availability (inventory and
location) system for medical equipment in
hospital facilities.
Each Item will be coded with a unique barcode
and can be in one of the following status:
In Use
Each room will be coded with a unique barcode.
Each user will be equipped with barcode reader
glove and a mobile phone both wirelessly paired.
The mobile allows him to change item status or
i.e. scanning the room and the ECG cart when
entering the surgery room.
The system Tracks the location of each tagged item.
The system Tracks the tagged item current Status.
Each of the tagged items current Status & Location
are accessible to the users at all levels through the
mobile Or Desktop Clients.
Business Value Reports \ Data analysis - The system
will support the Hospital manger & administrator
decision making process by allowing them to produce
series of business reports from the data that was
gathered by the system. i.e.
Item Yearly Review Report
 Lookup failures for department Report
The system architecture is A client-server based on 4 layers:
Layer 1: Database
Layer 2:
Web Service\Application Server
Layer 3:
2 Types of UI clients
Layer 4:
Item Identification Device (barcode
Application Server
Mobile Client
Barcode Reader
Web Service
Database Server
Desktop Client
ScanTask Bar code reader
The barcode reader device which will be worn on the
nurse's hand.
The device has the ability to read barcode notes and
deliver them to the paired mobile client over
Bluetooth channel.
Mobile client
A regular cellular phone, with a client application
installed on it.
 The client application will serve as a gateway for the
barcode to communicate with the system.
 It will also be a mobile UI with a basic query engine
that will have the ability to generate queries and
receive answer from the web server.
Desktop Client
Second client application which is an extended
version of the mobile client with more advanced UI
and query engine capabilities such as BI Reports and
administrative abilities
The application will be deployed with ClickOnce
technology which simulates web Style application
with a normal "localhost" application.
Web Server\Application Server
The web server is an xml based web service.
 It is the main communication junction between the
client and database server.
 It is also contains the Business Logic Processing
Database Server
The database server will be a dedicated service that
will provide a database service to our system.
Loose coupling between layers That Allows More Business
i.e. The system UI implementation are separated from business logic
engine component which gives the ability to change system
orientation from hospitals to any other industry quite easily
 Database independence - DB can be changed from mySql to MS Sql
server \ Oracle etc due to Architecture and ORM usage at the Server
Data Layer.
 Another example is the item identification hardware - At the moment
the system works with barcode reader but easily can be changed to
any other hardware device such RFID etc.
Interoperability with other ERP Services
The system server can be consumed by clients on other platforms even
in different development languages (Support for any language) &
Anytime – Anywhere \ Internet friendliness
the system is highly accessible from any place at any time under
security limitations (Login, User validation etc...).
Ease of maintenance
{Must important aspect - Through maintainability, you can achieve
anything else at any time. Security , Performance , Usability , Testability
Maintaining High Availability By Minimizing downtime upon maintenance
Actions \ Version Upgrade With Strong update mechanism.
i.e. The desktop client is automatically updating upon launch, In cases of
maintenance or version upgrade one's only need to update the server and
the clients will be updated at launch without any manual intervention.
(With exception to changes made at the mobile client code itself).
Because each layer is independent of the other layers, updates or changes
can be carried out without affecting the application as a whole.
the system can scale Out and clients can work with more then one server
The Desktop Client was developed in .NET C#
 The Mobile Client was developed in Java Micro
Edition using Sprint Wireless Toolkit and
LWUIT library.
 The Web Service was developed in Java and
deployed over Apache tomcat with Axis2 package.
 The Web Service data layer is based on ORM
(object relational mapping) package - Hibernate.
 The Database platform is MySql.
