PRECAUTIONARY MEASURES

1.3.1

CHEMICAL RISKS

The individual operator is responsible for assuring that all possible precautionary measures are
taken against eventual risks associated with the use of the “Ellipse” instrument in clinical laboratory
settings. The manufacturer will provide the reagents kit and specific written information on the use
of each of the reagents.
It is important that the samples be well coagulated and then carefully centrifuged.
Samples which contain fibrinogen clots can obstruct the probe and lead to inexact sampling.
If blood samples containing gel are used, it is suggested that the manufacturer’s recommendations
be followed.
Immediately clean and remove any accidental leakage of reagent or other liquid.

1.3.2

ELECTRICAL RISKS

As with any electrical device, the risk of electric shock exists.
Is therefore necessary to take every precautionary measure possible when working with this, or any
other, electrical instrument to avoid contact with power supply wires, electrical components or
electronic boards.

1.3.3 MECHANICAL RISKS
Several precautionary measures should be taken when operating the analyzer:
avoid wearing very loose clothing or jewelry that could become tangled in the instrument’s moving
parts (e.g. the sample probe); whenever possible, operate the instrument with the main cover panel
lowered.
WARNING: Never attempt to service or substitute any part(s) of the analyzer when the
instrument is turned on.
Any and all technical repairs or servicing must be performed by specialized personnel only.

Chapter 02 – SYSTEM DESCRIPTION

2 DESCRIPTION OF THE SYSTEM
"Ellipse" is a random access, computer controlled, counter-top, clinical analysis instrument. The
system can perform 138 tests per hour and has a machine cycle of 26 seconds. Its execution time
ranges from a minimum of 18 seconds to a maximum of 1032, depending on the analysis method
chosen.
The first time the system is used for laboratory analyses, the operator must configure the system
based on the specific needs of that laboratory; i.e.: the chemistry parameters and the reagents racks,
along with the normal ranges, calibrated and control values, must all be defined.
The daily routine analyses will be carried out according to patient sample arrival in a sequential and
continuous, non-stop manner.
The work list is organized using a loading rack holding up to 8 patient samples. Rack loading is
non-stop.
The racks can accommodate both test tubes and micro cups. The bar code for primary tubes and
reagent containers is an optional feature.
When the system, the analytical unit and the computer, is turned on the color-meter lamp is supplied
with low voltage power (1.2 volts), the sampling arm pre-heater remains turned off, while instead
the reaction plate heater, the reagents refrigerating unit (optional module) and the electronic
components are turned on.
In this phase, the "Stand-by" light, placed on the front panel, will flash until the reaction plate
reaches a temperature of 36° C. When this temperature is reached, the "Stand-by" light will stop
flashing and will remain constantly lit.
In the case of system failure or malfunction, the "Ready" light, situated on the front panel of the
instrument, will light up red.
In order to access the main program, double click on the "Ellipse" icon on the computer desktop.
The main menu - "System Monitor" - will appear.
Whenever any system function is launched, the color-meter lamp and the sampling arm pre-heater
will receive regular power.

Chapter 02 – SYSTEM DESCRIPTION

2.1 ANALYSES CYCLE
2.1.1 REACTION PLATE
The reaction plate of the "Ellipse" system contains 6 disposable racks with 20 reaction cuvettes
each.
The racks can be removed individually.
The basic operating cycle of the reaction plate takes 26 seconds. This cycle includes: optic reading
of the cuvettes in incubation, aspiration and dispensing of the reagents and the samples by the arm,
along with the relative positioning of the plate .
The reactions take place at 37° C. This temperature is maintained constant by a controlled heating
unit placed under the reaction plate .
2.1.2

REACTION PLATE CYCLE

After reagents and samples have been placed in cuvette #1, the reaction plate will rotate 40
positions counter-clockwise, so as to bring the first cuvette to be analyzed in front of the colormeter for reading with either one or two wavelengths, as required.
The plate will then, moving counter-clockwise, carry out all the readings of any other prepared
cuvettes. After having effectuated all the readings, the plate will move counter-clockwise to its
initial position minus one cuvette, ready for a new dispensing.
In this manner, the reaction cuvettes move clockwise 1 - 2 - 3 – 4 for dispensing, washing and for
their relative readings.
2.2

SAMPLING ARM - OPERATIONAL SEQUENCE
1. The sampling arm lifts up from the wash well and carries out a wash cycle;
2. The arm moves toward the specific reagent container, while the diluter aspirates an air
bubble to separate the rinse column from the reagent;
3. The arm lowers itself into the reagent, below the level indicated by the sensor, and aspirates
the required quantity of reagent. If the method requires a Rinse (used in order to reduce the
possibility of negative contamination between the water column and the reagent) an extra
amount of reagent (not used in the analysis) will be aspirated before the quantity of reagent
necessary for the analysis, along with another air bubble for their separation;

Ellipse

Service Manual

Rev. 03

01 June 2009

Page 3

Chapter 02 – SYSTEM DESCRIPTION

4. While the diluter aspirates a second air bubble, the arm rises and then lowers into the wash
well so that it can be washed externally, to minimize cross contamination;
5. The arm moves to the specified sample and aspirates a third air bubble;
6. Once the level sensor has indicated the presence of the liquid, the arm stops and aspirates
the sample;
7. The arm once again is raised, while the diluter aspirates a fourth air bubble to prevent
sample loss;
8. At this point, the arm returns to the wash well in order to clean the outside of the probe and
aspirates a fifth air bubble;
9. The arm moves to the reaction PLATE , dispenses, and mixes the reagent and sample in the
reaction cuvette for incubation and reading;
10. The

2.3 WASH STATION
The reaction plate wash station is made up of a series of five small needles situated on one side of
the reaction PLATE . Said needles are opportunely connected to the valve and pump system for
emptying, washing and drying operations (please see the hydraulic diagram).
2.3.1 WASH STATION CYCLE
The wash station carries out its operations alternating upward and downward movement. In its
downward movement phase the needles are guided in such a manner as to carry out the following
operations:
•

The first needle, using the central cannula, removes the reaction mix while the external
cannula dispenses, shower-like fashion, the wash solution; after that the external
cannula dispenses wash solution and then the liquid is aspirated from the central
cannula;

•

The second needle operates exactly like the first but uses distilled water instead;

•

The third needle operates exactly like the first but dispenses rinse solution into the
cuvette so that an optics check can be performed (if the results are negative, the cuvette
is discarded);

•

The fourth needle aspirates the control water;

•

The fifth needles dries the sides.

All these operations are part of the routine operation of the instrument. Every reaction cuvette is
washed at the end of each round of analysis.
The reusability (optical integrity) of each reaction cuvette is always tested before the next round of
analysis.

the Analytical Control Board, by two distinct flat cables, for transmitting all the I/O signals. The
only difference between them is the R1 resistor value. On the boards, the (FD1) photodiode reveals
the signal arriving from the relevant reading channel; the Amplifier (U2) amplifies the signal, which
is then inputted in the serial converter ADS 1250 (U3) for its conversion A/D.
From the Analytical Control Board they receive also two continuous voltages (+VB and –VB).
All the components dedicated to the signal amplification or digital conversion are mounted on the
same boards.

3.1 UNPACKING
The ELLIPSE is packed and delivered in two separate wooden crates: one contains the
analyzer itself and the other the computer, along with its accessories. In the event that the order
not include the PC component, packing and delivery will involve one wooden crate plus a
corrugated cardboard box. The packing has been expressly studied and designed to insure
maximum protection of the contents during shipping and handling. It is therefore extremely
important that the crate(s)/box be carefully examined upon delivery in order to ascertain their
integrity. Special attention should be dedicated to examining the color of the “Shock Watch”
glued to the crates, which must show the color ‘white’. A ‘red’ “Shock Watch” indicates that
the crate(s) have experienced some sort of ‘shock’ during handling, transport and/or delivery.
This fact must be noted by the courier on the delivery note, as must any and all visible external
damage (for example: holes, dents, rips or tears, water marks, etc.) evident at the moment of
delivery. This will simplify matters in the event of any future claims for damages.

Upon arrival of the crate(s)/box, take out the
delivery note and make sure that all the items
on the packing list are included in the crates
and are undamaged. Make sure the series
number on the delivery note/packing list
corresponds to that impressed on the plate on
the right side of the instrument.

INSTALLATION

The ELLIPSE must only be installed by a qualified technician who has been authorised and
trained to do so. During its installation the system will be checked once again to ensure correct
functioning. The persons who are required to operate the ELLIPSE system must have received
the adequate training. This should also include the "know-how" of the normal maintenance for
the instrument. A description of the maintenance will be found in Chapter 7 of this manual.
ELLIPSE is a complex system, and it is therefore extremely important that it is correctly
installed in order to fully guarantee fine performance. If the installation and use directions,
given in this manual, are not correctly followed and/or security indications are not respected,
AMS cannot guarantee correct functioning of the instrument. Apart from this, the security of
the operator could be placed at risk.

Gap: defines the volume, in µL, of the air bubble that separates the Rinse (the liquid column into the
sampling arm tube) from the sampled reagent; this volume must be set in the range from 10 to 24
(Standard value 16).
For the correct setting of the gap volume it is necessary to apply the procedure of BIB (Precision
check of the Analytical plate) and BIC (Volume precision check of the Sampling line).
If BIC’s CV values should exceed the limit specified below, the GAP has to be increased by
steps of 2 µL (starting from 10 µL) until obtaining the expected BIC’s CV value

SAMPLING PROBE – CLEANING PROCEDURE
1)

Turn off the Analyzer

2)

Use only lint-free paper towelling or gauze

3)

Dampen the gauze or paper towelling with distilled water and clean the outside of the
sampling probe. Wipe the probe from the top downwards only! This is to avoid that
any bits of cloth, paper or lint fibres accidentally enter the probe itself.

4)

The manufacturer suggests that once weekly the above-described cleaning procedure
be performed using, instead of only simple distilled water, a 5% sodium hypochlorite
solution to dampen the gauze and then be repeated using distilled water.

WASH STATION CANNULAS – CLEANING PROCEDURE
1)

Turn off the Analyzer.

2)

Place a sheet of paper under the wash station cannulas in order to keep any extraneous
material from accidentally falling into the cuvettes.

3)

Use only lint-free paper towelling or gauze.

4)

Dampen the gauze or paper towelling with distilled water and clean the outside of the
cannulas. Wipe the cannulas from the top downwards only! This is to avoid that any
bits of cloth, paper or lint fibres accidentally enter the cannulas themselves.

5)

The manufacturer suggests that once weekly the above-described cleaning procedure
be performed using, instead of only simple distilled water, a 5% sodium hypochlorite
solution to dampen the gauze and then be repeated using distilled water.

WASH SOLUTION BOTTLES – CLEANING

During normal use and over time, mold and dust can build up inside the wash solution bottles.
For this reason, it is extremely important that they be periodically washed. Said cleaning must be
thorough and meticulous in order to insure that every trace of mold or residue be removed.
How often the bottles must be cleaned depends on their use and on the quality of the distilled water
used in that particular laboratory. However, the manufacturer recommends thorough washing at least
once every two weeks.
It is extremely important that the user not underestimate the risks associated with mold and dust
particles. They are to be regarded as a serious hazard as they can be the cause of instrument
malfunction.
The wash solution bottles are located on the right side of the analyzer.

Chapter 07 - MAINTENANCE

7.5.1 WASH SOLUTION BOTTLES - CLEANING PROCEDURE
1) Turn off the Analyzer.
2) Pull the level sensor connectors out from the bottle caps.
3) Take the caps off the bottles and empty them.
4) Fill each bottle with a 5% sodium hypochlorite solution.
5) Clean the inside of each bottle using a bottlebrush in order to remove all traces of mold
and/or residue.
6) Leave the sodium hypochlorite solution stand in the bottles for at least ten minutes.
7) Empty the bottles, rinse them repeatedly and well with tap water, and then twice more
using distilled water.
8) Dry the bottles.
9) Fill the bottles with their proper solutions.
10) Replace the bottles in their respective housings.
11) Close the bottles and reconnect the level sensors.
12) Carry out two ‘Wash Cuvettes’ cycles and two ‘WBL’ cycles. Check system efficiency
by comparing the WBL values and the test results obtained against the laboratory’s
quality control values.

7.6

TIP WASHING

The Tip is used to dry the cuvettes after they have been washed. This drying process is carried out via
aspiration and therefore, over time, the Tip will necessarily absorb various contaminating particles.
The manufacturer suggests that the Tip be replaced every six months. Said frequency may vary
depending on the workload of the individual laboratory and the operating conditions/environment of
the single instrument.
The Tip must be washed regularly in order to guarantee proper functioning and must be replaced with
a new Tip as necessary.

6.

Once the cannula has been removed, immerge it in a 5% solution of sodium hypochlorite for at
least 15 minutes (Fig. 5).

7.

Attach a 10 ml syringe to the cannula and aspirate and dispense the hypochlorite solution
through the cannula (and the Tip) until the latter is completely clean (Fig. 6). This aspirating
and dispensing forces the liquid through the Tip fibers in both directions

8.

Once the Tip is clean, repeat the aspirating and dispensing cycle 10 more times using distilled
water, then disconnect the syringe.

9.

Re-connect the aspiration tube to the cannula (Fig. 7).

HYDRAULIC CIRCUIT WASHING

During normal use and over time, mold and dust can build up inside the wash bottles and can have a
negative effect on the hydraulic circuit, compromising the correct functioning of the micro-pump and
valves. This, in turn, can lead to inefficiency in the sampling probe and cuvette washing system.
For this reason, it is extremely important that the hydraulic circuit be periodically washed. Said
cleaning must be thorough and meticulous in order to assure that every trace of mold or residue be
removed.
How often the hydraulic circuit must be washed depends on the operating conditions/environment of
the single instrument and the quality of the distilled water used in that particular laboratory. The
manufacturer recommends thorough washing at least once a month.
It is extremely important that the user not underestimate the risks associated with mold and dust
particles. They are to be regarded as a serious hazard as they can be the cause of instrument
malfunction.
The hydraulic circuit input cannulas are located inside the bottles on the left side of the Analyzer.

7.7.1 HYDRAULIC CIRCUIT - CLEANING PROCEDURE
1)

Turn on the Analyzer.

2)

Prepare a bottle containing 500 ml of a 5% sodium hypochlorite solution

3)

Insert the four aspiration cannulas, located inside the liquids bottles, into the bottle containing
the sodium hypochlorite solution.

4)

Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle.

5)

Wait for fifteen minutes. Clean and dry the three cannulas and then insert them into a bottle
containing distilled water.

6)

Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle.

7)

Insert the four aspiration cannulas back into their respective bottles. Said bottles should have,
in the meantime, been cleaned and filled with a fresh supply of the required solution.

8)

Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle. Check system
efficiency by comparing the WBL values and the test results obtained against the laboratory’s
quality control values.

CHANGING THE PERISTALTIC PUMP TUBES

The manufacturer recommends that the Peristaltic Pump tubes be replaced every six months. Said
frequency may vary depending on the workload of the individual laboratory. The quality and
reliability of these tubes is fundamental to a correct emptying of the cuvettes.

7.8.1 PROCEDURE FOR REPLACING THE PERISTALTIC PUMP TUBES
1. Open the panel located on the right side of the instrument pushing down the looking door(Fig. 1).
2. Unhook the hinged guide by pushing the pin toward to the left (Fig. 2).
3. Pull the tubes off their relative nipples and substitute with new ones (Fig. 2).
4. After having unlooked the hinged guide, disconnect the tubes from their nipples
5. Remount, repeating the above steps, 4 through 2, in reverse order. Turn clock wise the peristaltic
pump rotor, in manual way, in order to be sure that tubes are right positioned inside the guide.

8.2 PROTOCOL SPECIFICATIONS
This part of Help (Protocol Specifications) contains information for the laboratory computer and
analyzer. This exchange of data follows specific ASTM protocols:
E 1381-95 Standard Specification for Low-Level Protocol to Transfer Messages
between Clinical Laboratory Instruments and Computer Systems;
E 1394-97 Standard Specification for Transferring Information between Clinical
Instruments and Computer Systems.
ASTM uses a number of different terms to indicate the way it groups data.
•

Field: an individual piece of data often referred to as a data field or a data element.

•

Record: a number of logically related data fields grouped together to form one part of a
complete message.

•

Repeat field: a data field of the same type as the one immediately preceding it. A delimiter
separates one instance of a repeat field from the next.

•

Component field: part of data field that might contain more than one piece of data.

The default communication configuration for the Analyzer is the following: "9600,N, 8,1".
ASTM uses record types that are common and familiar to all laboratory personnel. It uses the
following record types:
•

Header Record (H): contains identifying information about the sending station,
conventions that the device uses for field recognition, and the date and time of send station
transmission.

Ellipse

Service Manual

Rev. 04

Chapter 08 – Host Communication

•

Patient Record (P): contains patient information and identification number.

•

Test Order Record (O): contains information about the assay or requests themselves and
includes other data.
Result Record (R): contains information about the outcome of individual tests for an

•

individual patient and follows a sample program record. The results contain the actual
measurements derived from the test and a comparison of the individual result to certain
ranges specified as norms for the laboratory.
Message Terminator Record (L): although the ASTM protocol supports three additional

•

record types - a Request for Information Record, a Scientific Record and a Manufacturer's
Information Record - the Analyzer is not implementing these in the first release and will
ignore them.
Request Information Record (Q): is used by either clinical instruments or computer

•

systems for a remote request for information from its reciprocal system.

9.1

ERROR SIGNALING

This chapter is dedicated to a description of the error signalling which may occur during the
programming or carrying out of the various operations. Error signals can be divided into the
following two groups:
➢

System Errors

➢

Result Flags

9.1.1 SYSTEM ERRORS
Whenever a system error is detected, it is signalled via the activation of the below-listed
warning lights/buttons:
➢ Warning Light: a triangle-shape located in the upper, right-hand portion of the System

Monitor screen. It lights up yellow when activated.
If this yellow triangle does light up, the operator need simply click on it to access the relative
visual text warning message indicating the cause of the signalled anomaly (said window will
open in that area dedicated to viewing data).
Following is a list of possible visual text “Warning!” messages:
•

Liquid Alarm I (Rinse Solution)

•

Liquid Alarm II (Distilled Water)

•

Liquid Alarm III (Cleaning Solution)

•

Liquid Alarm IV (Optional Solution)

•

Temperature Out-of-Range

•

Host Serial Port cannot be opened

➢ Fatal Error: an “X”-shape located in the upper, right-hand portion of the System Monitor

mask. It lights up red when activated.
If this red “X” lights up, the operator need simply click on it to access the relative visual text
message explaining the cause of the Fatal Error (said window will open in that area of the mask
dedicated to viewing data).
Following is a list of possible Fatal Error visual text messages:
•

Horizontal Arm Error

•

Sample Tray Error

•

Filter Error

PHYSICAL ERRORS

R

CONCENTRATION ERRORS

C

CALIBRATION ERRORS

A

OPTIC DENSITY ERRORS

E

RESULTS EDITED MANUALLY

?

PROGRAMMING ERRORS

Every Result Flag, signalling an error, is accompanied by a symbol representing the group it is
part of. The operator need only click on the small red square ( ) next to the Result Flag symbol
to access the visual text message explaining the cause(s) of the signalled error.
In the central column of the following tables, the user will find those symbols which signal the
type of error encounter, as used in the print-out of the final report. These symbols can be
modified by the operator, in the Parameters section, under print options.
