GENERALINTRODUCTION

ELETTRONICA VENETA S.p.A. has been designing

and manufacturing educational equipment since 1963.

This equipment, covering the different fields of technology,

fulfils two important educational objectives:

• to facilitate the learning process of the student by

means of real systems which illustrate practically the

important aspects of the theory learned in the classroom.

• to simplify the work of the teacher enabling the demonstration

of the real, practical applications of the theory learned.

Increasing the efficiency of the didactic process improves and

simplifies the integration of young students into the world of

employment and justifies the material and human investments

made in schools throughout the world.

ELETTRONICA VENETA S.p.A. operates on an

international level and takes into consideration the

training programmes and cultures of each specific country.

In order to meet different requirements, we offer flexible

systems which ensure maximum compliance with the latest

technologies, technological advances and the professional

profile requirements of local industry.

The proposed laboratories and training equipment are suitable

for regular school education as well as ongoing post-diploma

training courses and professional re-qualification.

Our training equipment covers most of the technological

sectors included in the training programmes of vocational

schools, technical institutes and universities, both national

and international.

ELETTRONICA VENETA S.p.A. headquarters is located in the

green fields of the Veneto region, not far from Venice, and

constitute a centre for equipment design and development

suited to the training needs of all professional and technical

profiles. The modern premises integrates R&D laboratories, a

production plant and a fully equipped teacher training centre.

The integration of these efficient training systems into local

school structures ensures high-quality, state-of-the-art

training programmes which meet the diverse professional

expectations of the student and the technological requirements

of industry and research within their specific local contexts.

The ISO 9001 (Quality System Certification) obtained in

1998 and updated in application of the latest edition of the

International Standard, is further testament to the quality-

driven organisation of ELETTRONICA VENETA S.p.A. aimed at

providing top standard equipment, training and service.

1

The important technological development of electronics in

recent years has led to a large scale diffusion of a new concept

of systems including more and more sophisticated electronic

components.

Even in the medical field the evolution of technology has

introduced various innovations on the equipment used in the

treatment methods of different types of pathologies.

At present, more and more sophisticated equipment and

techniques are applied in MEDICINE to facilitate both

diagnosis and therapy. The recording of physiological electrical

signals (EEG, ECG, EMG…) or the diagnostic method through

images (CAT…) that reproduces body sections of patients with

tridimensional graphic processing, detect pathologies that

would not be recognized by traditional instruments, showing

thus to be a reliable and essential instrument for the doctor.

This situation leads to the need of new professionals with an

adequate education in basic electronics and a good knowledge

of applications in specific sectors such as biomedical

equipment. The in-depth knowledge of a biomedical apparatus

is necessary to carry out the correct installation, safety check,

control of performance and routine/extraordinary maintenance;

consequently this requires a basic theoretical-practical training

in the electronic field.

Consequently, the issue of basic training of technicians for the

maintenance of biomedical systems has a strategic importance

for the medical centres using electromedical equipment.

After a in-depth international survey and thanks to an

experience of many years in the fields of electronics and

automation, Elettronica Veneta S.p.A., has developed a

specific training programme for the “Biomedical” sector to train

technicians with an adequate and versatile preparation.

The different topics are organized to build an educational

programme including both theoretical introduction and

practical experiments:

• study of BASIC ELECTRONICS as introduction to biomedical

applications (optional preliminary step) and basic training in

the ELECTROMEDICAL Sector • VOCATIONAL TRAINING with some examples of

instruments in the sectors of Pathophysiology and

Diagnosis, Rehabilitation, Analysis Laboratory, and Software

for the maintenance of biomedical equipment.

The study of basic electronics and of the biomedical sector

is dealt with the setting of an Electromedical Laboratory consisting of some stand-alone workstations for students and

one for the teacher. The basic parts of the system are indicated

here below:

• Individual control unit for managing the interaction between

user and automated control system

• Testing modules of electronics and electromedical equipment

• Personal computer used by students for study and guide to

exercises, and by teacher to collect and process the results

• Educational software for individual study and acquisition of

biomedical signals

Vocational training aims at giving a set of knowledges and skills

sufficient:

- to know the general operation of existing equipment

- to install, calibrate and repair the instruments that do not

require the supplier’s intervention

- to maintain and test the electrical safety of the equipment

- to cooperate with medical personnel both in everyday use

and in the technical assessment of new required equipment

The equipment for Vocational Training includes some

examples of real biomedical systems, a system to test electrical

safety devices and a multimedia software to study preventive

and periodic maintenance procedures.

• INTERACTIVE PRACTICAL LABORATORY FOR STUDYING GENERAL AND BIOMEDICAL ELECTRONICS - I.P.E.S. system with modules of Electronics and Biomedical Equipment

• PROFESSIONAL INSTRUMENTS, ELECTRICAL SAFETY DEVICES AND SOFTWARE FOR MAINTENANCE OF BIOMEDICAL EQUIPMENT - Instruments for Pathophysiology, Analysis and Rehabilitation - Equipment to study electrical safety devices - Software for preventive and periodic maintenance of instruments for Pathophysiology and Diagnostics, Analysis, Rehabilitation and Radiology

The range of equipment produced by ELETTRONICA VENETA S.p.A. for the creation of Laboratories for maintenance technicians of BIOMEDICAL equipment is divided into two sections:

requirements: in fact it enables to carry out theoretical-

practical-experimental courses in very short times, manually

or with the aid of a computer. Courses will start from the

study of basic electronics and then they will deal with other

technological sectors depending on this subject: autotronics,

industrial electronics, telecommunications, biomedicals,

consumer electronics, hydronics, etc...

INTRODUCTION

Using a Personal Computer via USB interface enables to load the

desired specific biological waveform each time.

This function shows to be flexible and useful for the fact that the

biological waveform can be loaded from the Personal Computer,

and each waveform can be specifically plotted by a simple text

editor. Thus waveforms customized with anomalies (ECG with

cardiac anomaly, anomalous tracing…) can be output.

This production function of the unit is used for all exercises

with acquisition, processing and display of biomedical signals.

SIGNALS:The biological waveforms that can be selected are: ECG1, ECG2,

ECG3, EEG, EMG, US1, US2 and US3 (waveforms created by the

user).

FREQUENCY: 40 / 80 / 160 events/min

AUX: to adjust the value of AUX input of the generator; each

signal can be adjusted between –5V and +5V.

Every waveform other than the three or more main forms can

be included in the generator as a file by the mere definition of its

graphical form through points at regular intervals (time samples),

either for standard waveforms and for those with pathologies.

• EEG signal (output 0.1mV)

• EMG signal (output 0.4mV)

• AUXILIARY signal for adjustment

• Pathological waveforms (output 0.1mV)

SIGNAL GENERATOR SOFTWARE

The controls of software instruments are the following:

• Selection of signal to be output: ECG1, ECG2, ECG3, EEG,

EMG, US1, US2, US3

• Frequency: 40,80,160 Hz

• Offset of displayed waveform

The SIGNAL GENERATOR/ACQUISITION and FAULT INSERTION UNIT mod. GAU/EV is an essential element

enabling to use biomedical modules.

It ensures the following functions:

1. production of physiological signals such as ECG, EEG and EMG, required by module EB-B1/EV

2. Acquisition and display of the signals detected and processed by module EB-B1/EV

3. Interface with module EB-B2/EV (Printer)4. USB interface with the Personal Computer5. Fault insertion or circuit variations in biomedical

modules

This unit will output electrical signals with waveforms

equivalent to the biological ones (ECG, EMG and EEG) that

are properly processed and normalized to replace an actual

patient.

The output signals enable to perform the experiments with

modules more rapidly; they also solve the problem of the

noises appearing during actual signal acquisition (ARTEFACTS),

which should otherwise be identified and removed.

1. PRODUCTION OF PHYSIOLOGICAL AND CONTROL SIGNALS FOR MODULE EB-B1/EV

This section of unit GAU/EV enables to produce electrical

signals with waveforms equivalent to the biological ones (ECG,

EMG and EEG) that are properly processed and normalized

to replace an actual patient. It is used in tests requiring the

production of simulated signals coming from the human body.

This section can output the three following types of signals:

• Electrocardiogram ECG signal

• Electroencephalogram EEG signal

• Electromyogram EMG signal

SOFTWARE FOR DISPLAY OF BIOMEDICAL SIGNALS

The controls of software instruments are the following:

• CONT: for continuous display of signal. The signal is acquired

and displayed. Every new display replaces the previous one.

• SING: to control the display of each signal. The signal is

acquired and displayed. The previous signal is not canceled.

Different colors are used to distinguish the subsequent

displays.

• CANCEL: to cancel (eraser icon) the signal displayed by the

instrument.

• TRIG: to enable or disable the trigger. It is possible to specify

a value delay (Del cursor) referred to the trigger moment

when acquisition starts.

• STP: to set the acquisition start and therefore the duration of

the signal having to be displayed.

• TRG: to set the trigger value.

• DEL: to set a delay after trigger level where the signal

acquisition should be made.

Moreover this section includes Analog Outputs and ON/OFF

Inputs/Outputs so that unit GAU/EV can also be used in other

EXPERIMENT BOARDTesting modules are the main devices of IPES system; they

enable students to carry out all the programmed exercises

including the insertion of faults and variations of circuit

parameters, for an efficient educational worthiness.

These modules include a set of circuits already assembled and

they are connected with the Personal Computer via interface

mod. GAU/EV. These testing modules are directly powered by

unit mod. PS1-PSU/EV via a unique connector.

Each module is supplied with a handbook which guides students

in theoretical study, in practical tests and in troubleshooting.

It consists of a set of lessons for the modules of Electronics

MCMXX/EV and for the modules of Biomedical Equipment EB-

BX/EV; each set of lessons includes:

• a series of screens with theoretical explanation of the topic

under examination, and a sequence of simulations;

• a guide to exercises that shows circuits, questions, practical

exercises, automatic insertion of faults and variations of

circuit parameters.

Using this software, students can study and carry out practical

tests by themselves, without any additional literature.

The structure of this software, designed for use in Windows

environment, is provided with a multimedia graphical interface

enabling an easier use of the software, as well as the use of high-

definition images and charts with hypertext organization of the

topics under examination; before passing to the experimental

section students are favoured in understanding concepts by

proper simulations included in the theoretical section.

In the subsequent practical section, students will simply select

the various functions and answer to the questions appearing

in the section concerning exercises, by using the mouse; they

can also draw up reports or produce documentary information

on laboratory tests that are assessed by the teacher.

All the results are stored in students’ PCs, in self-learning mode,

and they are automatically sent to teacher’s workstation, in

laboratory mode.

Software

CLASS CONTROLmod. SW-X/EV

This software includes two sections:

• assignment of lessons and acquisition of results

• control of classes of students, processing and saving the

results

The first section of this software deals with the control of data

connection network.

It is used with the network software installed with an Ethernet

card, for a classroom of networked PCs.

This software enables the teacher:

• to assign a specific lesson or group of lessons having to be

carried out by each student. Different lessons or groups of

lessons can be assigned to each student according to his/her

learning level;

• to assign a lesson to be carried out by the whole class;

• to display the current state of the lessons completed, or

having to be carried out, for each student;

• to check the answers of each student, in real time.

The second section of this software is used by the teacher to

process the results of students’ answers.

Using this software, a teacher can manage various classes

and check the learning level of each student constantly, either

in a laboratory with microprocessor control unit and in a

multimedia laboratory.

Main functions:• Control of 90 classes;

• Control of 32 students per class;

• Entering students’ names;

• Automatic data gathering from control units;

• Progressive saving of the results from students’ workstations;

• Display of the temporary results concerning previous

lesson developments. The teacher can store the last lesson

completed as historical result, after a series of previous

attempts for completing the same lesson.

• Detailed and summarizing display and printout of students’

results. The results of each student or of each class attained

for any lesson developed can be displayed and printed.

• Graphic display of the scores for students’ answers for an

instantaneous overall view of the situation in each class.

• Detailed and summarizing printout of students’ results.

Recording the last temporary results as historical record for

each student or for each class. Different solutions of the same

lesson can be acquired for each student or for each class.

Using this option, a teacher can decide when the last result

must be saved as the most significant historical result for the

student or for the class.

EL.VE. EDUCATIONALAUTHOR SOFTWAREAUTHORING SOFTWARE FOR CREATING NEW LESSONS OR MODIFYING THE EXISTING ONES

The software consists of a set of programs that enables to

modify the various lessons for modules mod. MCMXX/EV and

EB-XX/EV.

New sections regarding theory and new exercises can also be

created.

This software consists of an editor for adding:

• theory pages

• testing pages

• footnotes to these pages

The formatting and general appearance of pages are determined

by special markers (tags) that include the information of text

layout and style, of the images to be placed in the overall layout

of pages, of the content of tables / boxes for data introduction,

of links with other pages, of colours of texts and backgrounds.

This program includes a Preview of the page being created

or edited. A simple command enables to display the page as

it would appear to students during the lesson. This enables

to speed up the process of creating educational material

considerably.

EDITOR of DRAWINGS, DIAGRAMS AND IMAGESThis program is used to plot drawings having to be inserted

into the pages of educational material. This tool simplifies

the creation of some types of drawings and wiring diagrams;

moreover it enables to touch up the images having to be

inserted into the pages of the lessons. Images in BMP and JPG

format are managed.

Z1/EVThe Z1/EV 8-bit microprocessor board is an educational system

based on the Z80 version of a microprocessor. It is designed for

an introductory study of microprocessor and of 8-bit systems

in particular.

The module includes all the components characteristic of

this kind of system (Z80 microprocessor, RAM and E²PROM,

keyboard and display, serial and parallel interfaces, analog

inputs and outputs and a fault control system).

The system is equipped with a considerable number of digital

and analog interfaces, thus enabling its application to different

sectors.

The machine code instructions, representing the program to be

developed, are usually inserted from the keyboard and shown

on the module display.

When the applications to be developed are too complex to be

performed with the on board peripherals, the system can be

connected to a Personal Computer by creating a Development

system with the following phases:

• Program writing into the PC in Assembler using a text Editor;

• Program compiling and linking for the machine code

transformation made by microprocessor;

• Program downloading, via serial or parallel interface, into the

RAM of the microprocessor system;

• Program debugging directly on the microprocessor module

with the module hardware interfaces;

• Transfer of the perfectly operating and completely PC

tested program to an E²PROM programmer for the definitive

programming of the E²PROM and its insertion into the proper

base of the microprocessor system.

Among these instruments, sensors and transducers of temperature, flow and of pressure have become particularly important; they provide an analog electric input that indicates the physical variables detected in different physiological instruments. But the effective use of this electrical information requires some system of electronic interface for connecting transducers with instruments: these circuits are commonly defined “signal conditioners” and they provide an output with voltage variable value in standard ranges not depending on sensor type.The first part of the circuit enables to measure the different sensors, whereas the second part provides a standard output voltage in a variable range, usually between 0 and +8 Vdc or 10 Vdc, that is the best range to be used by the corresponding process instruments.The module enables to study and apply the basics of transducers used in biomedical equipment.

INTRODUCTIONThis section contains a complete set of software packages.

These packages deal with all topics developed in previous

educational trainings, and guide users through video pages

in order to simplify the learning of the operating principles of

equipment and of the basics of maintenance of electromedical

equipment.

VOCATIONAL LEARNING SOFTWARE

The package consists of:

• Educational software for equipment of PATHOPHYSIOLOGY Mod. SB-F/EV

• Educational software for equipment of REHABILITATION Mod. SB-R/EV

• Educational software for equipment of ANALYSIS Mod. SB-A/EV

• Educational software for equipment of RADIOLOGY Mod. SB-D/EV

At the end of this section of educational training, students

will have completed their learning. As a matter of fact, this

integration of the instruments normally used in biomedical

fields enables students to attain a complete learning allowing

them to face the specific characteristics and the slightly

different functions of the various instruments produced and

offered by suppliers, easily. The instrument choice depends

on the specific learning needs. However, it is better to use a

range of instruments that constitute a limited but significant

subgroup, choosing among the wide range of electronic

instruments available in the biomedical field, in order to give

a basic training on medical equipment.

Each software consists of a set of multimedia classes that explain the topics indicated here below for each instrument: • Clinical use• Operating principles• Block diagrams• Safety rules• Preventive and periodical maintenance
