tubes of the equipment away from matches, lit cigarettes and
inflammable material, such as anaesthetic gases and/or so
urces of
heat.
•
Do not connect the anaesthesia unit to the patient by flexible
connectors, and antistatic or conductive tubes to prevent patient
burnings during the use of high frequency surgical equipment, specially
dangerous with antistatic tubes. The use
of flexible connectors,
antistatic or conductive tube is never permitted with MORPHEUS
anaesthesia unit.
•
Do not use worn and consumed tubes or tubes contaminated by
flammable substances like grease or oil to deliver oxygen; (fabrics, oil
and other fuels c

Introduction
User’s Manual, DU3310103-MRI / rev. 3 - 02.05.2019 1-1
1 PRESENTATION
SIARE ENGINEERING INTERNATIONAL GROUP s.r.l. is glad to introduce this new
product, result of 40 years of experience and investment in technological innovation
that we are implementing in recent years.
Siare has focused heavily on innovation of materials, ergonomics and ease of use. All
routine operations have been simplified and the operational procedures are
“foolproof”, in this way there is no margin for the user to make incorrect or inadequate
manoeuvres.
Even the maintenance procedures have been simplified and the parts subject to wear
or deterioration have substantially decreased. Siare invested much on this project
because we firmly believe that it will be a winning product.
1.1 Foreseen use
The MORPHEUS LT/MRI is an anaesthesia unit that can be used on adult, children
and newborn patients. The MORPHEUS LT/MRI is an anaesthesia machine
compatible for Magnetic Resonance rooms from 1,5 T (15000 G) and from 3 T (30000
G) and positionable at a min. distance from the magnet corresponding to a field of 20
mT (200 G).
The MORPHEUS LT/MRI is suitable for administration of Oxygen - Air - Nitrous Oxide
- Halothane - Enflurane - Isoflurane - Sevoflurane - Desflurane mixtures. The fraction
of inspired oxygen can vary from 21% to 99%.
1.2 Versions
To respond to the several requirements and market requirements, the MORPHEUS
LT/MRI anaesthesia unit foresees a unique trolley configurable for MRI.
The basic trolley is composed by the following modules:
•mechanic structure of the trolley,
•work-shelf,
•valves group,
•electric power supply module,
•electronic lung ventilator with DISPLAY,
•flowmeter box at 3 gas and 5 rotameters.

Introduction
1-2 MORPHEUS MRI
1.3 Main technical characteristics
1.3.1 Trolley
The mechanic structure of the trolley is made of completely non-magnetic materials.
The pedestal base is made of a shockproof ABS and polyester coated. This ensures
an excellent impact resistance thanks to its flexibility and excellent abrasion
resistance.
Its dimensions and weight are very reduced and allow its installation also in small
rooms or small working areas or combined with pendant lifting systems.
The work-shelf is mono-bloc, made of a unit PUR mould. The shelf also includes the
housing for the valves group and the manual ventilation controls. The shelf is very
wide and the large handle below the perimeter allows to hold and easily move the
unit.
On the left side a steel rod at full height is provided for fixing the patient monitor and
other accessories like for example the supporting arm for patient circuit, infusion
pumps, etc.
The lateral uprights are provided with a vertical guide for fixing the accessories or
lateral devices, e.g. the pendant lifting system, lateral lectern or PC support for
medical record writing.
On the back side are the medical gas intakes, which are positioned in a rational and
easily visible way. The intake for main supply system and pressure reducer-cylinder
are also provided, with a non return valve and automatic change. In case of main gas
failure just open the cylinder and the gas will be immediately available for use without
additional manoeuvres.
1.3.2 Valves group
Completely renewed and performing, it presents the following definite advantages.
•Extraction from above and perfect integration with the work-shelf.
•Automatic connections with double seal gaskets against accidental leaks.
•Mono-bloc, fully sterilizable in autoclave
•Automatic flow sensor and oxygen sensors calibration procedure activated by
operator
•The access to flow sensor and O2sensor is simple and immediate.

Introduction
User’s Manual, DU3310103-MRI / rev. 3 - 02.05.2019 1-3
•The CO2absorber canister is located in the upper side and it easy to disconnect
by apposite unlock lever. With canister inserted the system makes automatic
configuration in rebreathing modality; with taken off canister, the system makes
automatic configuration in non rebreathing modality (real open circuit). It is
possible to put and take off the canister during intervention. The canister is
available in version for reuse and disposable version including soda lime
granules.
•Low periodic and extraordinary maintenance operations; easy training of
technical personnel thanks to the extreme rationality of the system and to the
drastic reduction of accidental leaks.
1.3.3 Flowmeter box
The flowmeter box is available at five rotameters; it is characterized by the complete
absence of mechanical controls; replaced by a small control panel located on the left
side of the work-shelf to manage all manual ventilation operations. This solution
allows the presence of audible and visual alarms of strong impact and without
duration limits.
1.3.4 Lung ventilator module - DISPLAY
The lung ventilator module, through user’s interface, allows to set and display the
main respiratory parameters useful for the operator to use the MORPHEUS LT/MRI
anaesthesia unit.
The lung ventilator module foresees the following operative modes: MANUAL, VC-
VAC, PCV-APCV. This ventilator type is characterized by a very simple user’s
interface and by an important novelty relevant to the presence of PRESET programs
for adults, children and newborns.
The passage from MANUAL to AUTOMATIC ventilation is made by simple pressure
on the push-button on the keyboard alongside the DISPLAY.
The valves group is automatically configured for the selected modality without any
manual procedures, avoiding errors or inadequate manoeuvres.
The lung ventilator module, foresees the possibility to ad just the end expiration
positive pressure (PEEP), the trigger sensitivity and is equipped with the FiO2
monitoring with automatic calibration and leak test.

Introduction
1-4 MORPHEUS MRI
For the controlled ventilation of newborn patients, make reference to
the chapter 7.4, about use with premature patients.
For a correct comprehension of MORPHEUS LT/MRI anaesthesia
unit operation and for a correct and safe use both for the patient and
user, the knowledge of recommendations and instructions indicated
in the present User’s Manual is required.
For anyone who already has basic knowledge of anaesthesia unit
functioning and of lung ventilation in general, the use of the user
interface is intuitive and it will be sufficient to consult this user’
s
manual
in order to use the MORPHEUS LT/MRI anaesthesia unit
correctly.
The lung ventilator module, incorporate a series of sensors for continuous patient
monitoring, the most important of which are:
•the flow sensor on the expiratory line, used to measure the expiratory volumes of
the patient;
•the pressure sensors, used to control the pressure of the airways or of the
medical gases;
•the oxygen sensor, used to measure the concentration of oxygen in the gas
inspired by the patient.
The operator must check the functioning of all these sensors before
using the device in order to prevent incorrect assessments of the
patient’s condition.
