General Introduction

1. General Introduction

CardioServ Semi-Automatic and Manual

There are 2 CardioServ models: the semi-automatic and the manual defibrillator. Both models are available with a pacemaker and SpO2.

The manual CardioServ is a defibrillator designed to deliver synchronized and unsynchronized shocks. This requires the user to trigger capacitor charging and shock delivery manually.

The semi-automatic defibrillator is equipped with analysis software, which monitors the ECG for arrhythmias (fibrillation and ventricular tachycardia). When the analysis is started by pressing a key the ECG is analyzed. If the result of the analysis is positive, the capacitor is charged to the preselected energy level. The semi-automatic operating mode can be terminated by pressing a key or inserting the dongle.

Functional Description

3. Functional Description

The Therapy System CardioServ comprises a defibrillator, a monitor ( LC display 240 * 320 pixels ), a printer and a power supply unit. These components are arranged in a casing. It is a compact unit, which can also be implemented using a 230-V power supply system, even without a battery. The unit has a pulsed 140-mA standard charge for the battery. Additional versions available have an external pacemaker and an SpO2 module, separately or combined. The Defi is switched on by turning the rotary switch to position ECG or energy levels automatic sequence 2 ... 360 J. Following a self-test, which tests

- RAM data store

- ROM program memory

- Watchdog / Reset

- EEPROM permanent memory

- Display all Pixels on / off

- Time base of internal quartz crystal

- Energy charge from last shock

- Defective charge or Defib keys

- Position of energy selector switch

- Connected electrodes

- Pacemaker

- SpO2

the Defi is ready for operation. If an error arises, depending on the severity of the error, the Defi is either on standby or not. Serious errors are watchdog, ROM or RAM errors. In the case of minor errors, an error message appears, but the instrument can be rendered operative by pressing a key.

The Defi shock is delivered via exchangeable paddles. This permits the use of different electrodes. In addition to conventional electrodes, large-surface adhesive electrodes or internal electrodes, for example. Adhesive electrodes are used for the pacemaker. The CardioServ also has Charge and Trigger buttons on the instrument.

The charge operation is actuated with the Charge key on the apex electrode (for internal and adhesive electrodes on the instrument). During the charge operation, the accumulation of energy is shown on the display. When the selected energy level has been reached, the energy to be released appears on the display. An acoustic tone sequence and a message on the monitor indicate that the selected energy level has been reached. When the battery is fully charged or with line-power operation, charge time to 360 J should be about 8 s.

Version 4.x CardioServ - 11 Revision J 227 483 02

Functional Description

The buttons on both electrodes are pressed to trigger the defibrillation pulse (safety two-hand operation). This means that the button on the apex electrode (or the corresponding one on the instrument) has two functions:

- start the charge operation

- trigger defibrillation (together with the Trigger button)

The type of electrodes connected are identified and, in the case of internal electrodes, the energy is automatically limited to 50 joules.

Following defibrillation, the energy released is displayed on the screen for 6 seconds. Documentation output is by the printer.

The defibrillator has three operating modes:

* synchronized defibrillation (cardioversion) * unsynchronized defibrillation (emergency therapy) * semi-automatic (emergency service)

Cardioversion (operating mode Sync) can proceed either via the paddles or a patient cable. The operating mode Sync appears on the display and Sync marks are superimposed on the display. Following cardioversion, for safety reasons, the CardioServ switches automatically back to the unsynchronized operating mode. Before each cardioversion the instrument must be switched over to Sync mode. The Defi can be configured for semi-automatic operation in three ways: * As a semi-automatic instrument only (defibrillation only possible via analysis) * Semi-automatic instrument which can be toggled to manual mode by pressing a key * Semi-automatic instrument which can be reset into manual mode using a dongle

ECG signal pick-up is possible via the paddles or ECG cable. ECG is output on the LCD display or by the built-in 50-mm printer.

A safety device ensures the discharge of the storage capacitor in the following situations:

- when defibrillation is not triggered 30 seconds after storage operation is complete,

- 0.2 seconds after triggering defibrillation,

- immediately after switching back the energy selector switch during or after storage,

- when the battery voltage drops below a certain level,

- when the selected energy level still has not been reached after 32 seconds.

When switching to a higher energy level, the energy deficit is supplied by recharging.

- 12 - CardioServ Version 4.x 227 483 02 Revision J

Functional Description

Pacemaker

The pacemaker is a transthoracic pacemaker operating in the Demand and Fix mode.

- Pulse width 40ms (20 ms)

- The frequency is between 0...180 P/min (> 150 P/min only 20ms pulse width)

- The current is between 0...200 mA

- Adjustment is in 5-unit intervals.

The pacemaker is operated using 6 keys on the control panel. One key switches the pacemaker on, one key changes the operating mode, the other keys are used to adjust the frequency and current. The defibrillator cannot be disabled as long as the pacemaker is switched on. The adhesive electrodes of the Defi are used to release a pulse. This ensures a rapid switch from defibrillator to pacemaker and back again.

SpO

2

SpO2 is based on a module manufactured by Nellcor. This module is located on the PCB Analog and receives its power from the latter. Measurement of the oxygen saturation level and pulse frequency is made by this PCB. Pulse frequency from 0...250 P/min Saturation from 0...100% We display the plethysmogram, saturation level and, when selected, the pulse frequency instead of the HR.

Control options:

A battery charge check is performed under load application. The message “charge battery” on the display means the battery needs recharging. At least five discharges at maximum energy are still possible. (Possibly even considerably more)

Performance check of defibrillation is performed by discharging into the integrated 50-Ohm resistor.

Battery charge via the power cord connector can be monitored by the yellow LED. If the battery is fully charged after 16 h, trickle charging ensues, the yellow LED is permanently lit up.

The monitoring function of the CardioServ records and monitors the ECG and oxygen saturation level. The cardiac-action potentials are fed to the ECG preamplifier via a 5-wire patient cable. Selection can be made from 12 leads. The ECG curve is displayed on the LC screen with an illuminated background. The heart rate obtained from the ECG signal is continuously displayed on the screen.

Communication between the user and the instrument occurs via the keyboard and the LC screen. These also serve to configure the default settings and functions (see User’s Manual for further details).

Version 4.x CardioServ - 13 Revision J 227 483 02

3.2 Important Servicing Note:

Replacing CardioServ PCBs

When CardioServ PCBs are replaced the technician must call up the self-test screen after replacing the PCB. The new components are reported automatically in the software configuration. After restarting CardioServ recognizes the new components. This is important in the case of SpO2 and Pacemaker. Further the Performance Check (see section 10.4) needs to be accomplished.

Replacing PCB Digital

The identification numbers 0000 and 1111 are stored in the Eeprom of the PCB Digital for CardioServ Manual and CardioServ VF, respectively.

The replacement PCB always has the identification number 0000 stored in the Eeprom for CardioServ Manual.

If during servicing the replacement PCB Digital is inserted into a CardioServ VF, when it is switched on the CardioServ is in the manual mode. The following combinations of keys are required to switch the CardioServ from manual to semi-automatic operation.

1. Press F1 and F5 keys simultaneously: The function Configuration appears on the screen.

2. Press F3 and F4 keys simultaneously: The function Key Test appears on the screen.

3. Press the Analysis key.

4. Press F3 and F4 keys simultaneously.

The identification code for the CardioServ VF stored in the Eeprom of the PCB Digital is now 1111 and the CardioServ operates in the semi-automatic mode.

6. Assembly Instructions

General Information:

Before opening the CardioServ switch the instrument off, disconnect power cord plug, remove battery and implement ESD protection measures. Return replacement PCB in ESD packaging only.

Opening the instrument: Undo the 9 screws on the bottom of the device, place upper case shell to the left next to the instrument.

Removing the PCB Digital:

The PCB Digital is located in the upper shell. Disconnect the 50-pin flat strip cable and the 2pin 12-V power supply cord. The recorder, plugged into the lower case shell, can be removed and the flat strip cable connected to the thermal-array printhead and motor disconnected. Lay the upper shell “face down”, remove the screening plate fixed in place by a screw and 5 plastic catches. Remove the insulating card. Undo the 8 PCB Digital fastening screws (leave the 4 display screws in place) and remove the rotating knob of the energy selector switch. Carefully lift up the PCB and pull out the membrane keypad connector on the left. The PCB Digital can now be removed along with the display screen.

Removing the display screen:

-Disconnect plug-in connector to display illumination.

-Carefully pull the zero power connector safety catch of the display-membrane keypad

connector upwards and disconnect membrane keypad lead.

-Remove the 4 display fastening screws.

Removing the PCB Analog:

Disconnect 50-pin flat strip cable, connection cable to the battery, power supply unit and PCB Digital. Detach connector to the ECG socket and disconnect connections to Defi socket. Remove ECG amplifier cover with 3 screws and 2 plastic catches. Unscrew the 10 screws on the PCB Analog (4 capacitors, 2 high-voltage oscillators) and 3 hexagonal columns.

Assembly Instructions

Removing Recorder

Recorder can be removed by disconnecting the ribbon cable and take out the complete recorder.

Recorder Installation

It has to be prevented that any pressure to the print head or PCB print Head Adapter is applied if the upper housing shell is installed.

Situation 1: New print head assembly 2031154-001 in connection with PCB Digital with long print head ribbon cable

• Connect the motor and print head ribbon cable

• Lift the recorder unit ca. 2cm from it’s support

• Position the 4-wire motor ribbon cable beneath the PCB Print Head Adapter (1)

• Press the 30-wire print head ribbon cable onto the recorder housing and shift the recorder back into it’s

support

• Check that the cables are properly positioned

Assembly Instructions

Situation 2: Old print head assembly 30343976 without PCB Print Head Adapter in connection with PCB Digital with long print head ribbon cable

Proper recorder installation

Situation 3: New print head assembly 2031154-001 in connection with older version of PCB Digital with short print head ribbon cable.

• Enlarge the cut in of the 4-pol motor ribbon cable to ca. 4cm

- 36 - CardioServ Version 4.x 227 483 02 Revision J

Assembly Instructions

• Put the PCB print head adapter to the print head

• Connect the motor and print head ribbon cable

• Fold the print head ribbon cable into the gap between the recorder and the lower housing shell before

drop the upper housing shell. This prevents that the upper housing shell drags the print head cable down together with the print head. If this is ignored a bad print out can be occur.

Version 4.x CardioServ - 37 Revision J 227 483 02

Assembly Instructions

For final test please start a print out and verify the correctness. The test has to be done after the CardioServ’s upper and lower housing shell is closed and screwed together.

If the print head ribbon cable is not accurate mounted parts of the print out are not or not accurate printed.

If the ribbon cable is accurate mounted the print intensity is good and homogeneous.

Maintenance and Technical Inspection

10.5 Battery

A battery charge check can only be performed in the battery service unit Part No. 701 279 01. This tests takes at least 2 hours, max. 3 hours. The service manual for the battery service unit can be ordered under Part No. 227 494 11.

If no battery service unit is available, the battery should be replaced every 2 years.

Battery Maintenance

Proper maintenance of NiCd batteries is essential and considerably promotes their proper performance. Routine preventive maintenance should be carried out by qualified service technicians on a regular basis (recommended interval: 30 days). If batteries are repeatedly partially discharged, the resulting "memory effect" max dramaticaly reduce the battery capacity. This effect can be efficiently minimzied by regular conditioning. If the capacity of a relatively new battery is drastically reduced, the battery max be reconditioned by repeated charging and discharging.

Monthly Battery Maintenance (Conditioning) and Checks

1. Disconnect CardioServ from the power line and discharge fully charged battery in the monitoring mode. To do so, set energy selector switch to (SpO2 sensor not connected)

and wait until device switches off.

2. Check how long it takes before battery is depleted. If the time is less than 1.8 hours, the battery is too old or improperly maintained and should be replaced.

3. Recharge the battery. This will take 16 hours.

Rechargeable batteries require special maintenance and continued checks to assure they function in emergency situations. It is normal for batteries of this type to selfdischarge when not in use.

11. Safety Analysis Test

11.1. General introduction

The suggested Safety Analysis Tests refer to the international standard IEC 601-1. The tests are generally performed with Safety Testers, on most of them, the measuring circuits according IEC 601 are already implemented. The following is a general description of the tests to be performed. For the handling of your Safety Tester follow the user manual.

- 66 - CardioServ Version 4.x 227 483 02 Revision J

Safety Analysis Test

The tests may be performed under normal ambient conditions of temperature, humidity and pressure and with line voltage. The leakage currents correspond to 110 % of rated voltage for the tested unit. Most Safety Testers take this into account, otherwise the measured values have to be calculated.

11.2 Recommended Test Equipment

- Safety Tester for measurements according to IEC 601.

- Testing connector according to the following description.

11.3 Protective Earth Resistance Test

The protective earth resistance from power connector to any protective earth connected exposed conductive part is measured.

Because the protected earth is not connected to other touchable conductive parts (contacts to battery, contacts to car holder) “as a protected earth connection”, the protected earth resistance test is not necessary. These other touchable conductive parts are grounded just for EMC reasons. The protected earth begins at CardioServ AC connector and ends inside the CardioServ power supply on the left mounting screw, near the power supply line connector.

Notes to check this protected earth connection:

- Specification of test circuit:

- AC current source 50Hz/60Hz of at least 10A up to 25A with limited output voltage of 6V.

- If resistance is greater than 100 mOhm, the unit fails this test.

Version 4.x CardioServ - 67 Revision J 227 483 02

11.3.1 Leakage Current Measurement

To perform the suggested measurements, the unit under test has to be separated from any interconnection to a system. If the unit is part of a system, extended tests according to IEC 601-1-1 have to be performed. The following diagram shows the Measuring Circuit [M] required for leakage current. The reading in mV corresponds to μA (leakage current). The Safety Testers generally work with this Measuring Circuit [M] and the displayed values are already converted to leakage current.

Installation Instructions for the CardioServ Mounting System 202 307 01

* First of all, connect the mounting system to the

12-V power supply system of the ambulance (cable aperture on the underside of the mounting system, see terminal diagram).

* Connect the positive terminal (+12 V) to the free

contact of the fuse holder (4.8-mm sleeve enclosed). Connect earth (0 V) to the corresponding contact of the terminal block (4.8-mm sleeve enclosed). Please use the enclosed adhesive fastening base and the cable tie to fix the connection cables.

Observe the following points when connecting the mounting system:

- the negative terminal of the ambulance power supply must be connected to earth,

- the positive lead must be protected with a 10 Amp fuse (slow blow) and

- the lead diameter must be adequate.

* The mounting system has 4 bore holes both at the

top and bottom edges, allowing it to be mounted to the ambulance in a vertical or horizontal position (take care that the mounting system is flush against the wall of ambulance; in the vertical position the wider part with the cable aperture must face down!) (see Fig. 1).

* Replace the 4 rubber feet of CardioServ with the

metal feet enclosed. When screwing down the metal feet, please note that they have a recess on one side for the screw head.

* Use the appropriate type of screws for attachment

of the metal feet: If the CardioServ unit is equipped with metal bushings, please use the fillister head screws DIN 912 M 4 x 12; if there is no metal bushing but only a hole, please use Plastite screws 4 x 16.

* Please be sure to use the red feet (angular groove)

at the bottom, i.e., on the side with the contacts. (See Fig. 2).

* If required, you may attach the enclosed rubber feet

on top of the metal feet.

* Mount the CardioServ by first inserting the feet at

the bottom, then by introducing the feet at the top.

* To remove the device press on the latches (top

center).
