Soniciad Team Service Manual April 1996

1

General Introduction Two generations of the Sonicaid Team fetal monitor have been produced. This Service Manual has been written for the second generation. See section 1.1.1 “Identifying your system”, to identify the generation of your Team unit.

Note:

A Service Manual is available for the first generation of Sonicaid Teams - please contact Huntleigh Healthcare for details.

1.1 Introduction The Sonicaid Team fetal monitor consists of a base unit which collects the monitored information and a printer unit. This Service manual is applicable to the following base unit models:

Team Single fetal heart rate monitoring with an ultrasound transducer, and uterine activity with an external toco transducer.

Team Duo As Team, above, but with a second ultrasound transducer for monitoring twin fetal heart rates.

Team FECG Twin fetal heart rate monitoring by ultrasound transducers and invasively by a fetal ECG scalp electrode. Uterine activity can be measured either with an external toco transducer or an intra-uterine catheter pressure transducer.

Team IP Twin fetal heart rate monitoring either by two ultrasound transducers, or invasively by a fetal ECG scalp electrode and an ultrasound transducer. Uterine activity can be measured either with an external toco transducer or an intra-uterine catheter pressure transducer. Team IP can also measure the maternal heart rate (this feature is not currently available in the USA).

Team DM For use in a remote clinic or the patient’s home, Team DM provides the same facilities as Team, but includes a modem for transmitting stored CTG data.

This Service manual is applicable to the following printer unit models:

Standard Thermal printer for a continuous paper record of monitored CTG data.

Team Care Incorporates CTG analysis for use during the antepartum period.

IP Trend This printer incorporates a CTG analysis system for use during the intrapartum period. 2

1.1.1 Identifying your system The second generation of Sonicaid Team has the following distinguishing features compared to the first generation: 1 2 3 4

The base unit display is backlit The base unit keypad has tactile buttons The toco zero button is on the base unit keypad The symbols and other markings on the base unit and printer are on labels, rather than being silkscreened onto the case

1.1.2 Product description For a full description of the function and operation of the Sonicaid Team fetal monitor please refer to the Sonicaid Team User Manual.

1.1.3 Standards compliance Team is designed to comply with: • • •

IEC601-1 (1988) BS5724 Part 1 (1989) EN60601-1

Servicing MOD STATE The Mod State label on the underside indicates the modification state of the instrument i.e. the changes which have been made. A figure is struck through when the changes for that Mod. State have been done. Information in this manual which is applicable to certain Mod. States is indicated as such.

IMPORTANT: Servicing policy Due to the complexity of the electronics in the Team fetal monitor, the servicing policy is to locate, and return, the printed circuit board which is causing the problem. Huntleigh Healthcare does not supply surface mount components for the Team PCBs. For this reason, circuit diagrams are not included in this manual. Block diagrams and fault finding sections are included to make fault finding to leaded component level possible. If the problem cannot be located with absolute certainty, return the Team unit with full details of the symptoms. Boards which have been mutilated due to attempts at repair, or incorrectly packaged will not qualify for an allowance against the cost of a good board. The following procedure should be used: 1 2 3 4

Check and make a note of all the visible and/or audible symptoms of the problem. Check the power supply circuit, and the power supplies to each board. Check the clock and gating signals, and other waveforms, where indicated. Check the input and output signals or logic conditions where indicated.

Units within the warranty period must not be dismantled and should be returned to Huntleigh Healthcare Ltd for repair. Any units returned showing signs of tampering or accidental damage will not be covered under the warranty (refer to user manual for further details Antistatic Handling, Electro Static Discharge (ESD) The Sonicaid Team Series uses Electrostatic Discharge Sensistive Devices ESD’s) in its manufacture. The damage they suffer when handled incorrectly can be catastrophic. More often and potentially even worse, the damage may be partial or latent, seriously impairing the reliability of the unit. Due to the nature of the components used within the unit, special precautions must be taken to avoid damage to the circuitry. Static damage may not be immediately evident but could cause premature failure. The Sonicaid Team series must only be dismantled and serviced within an ESD protected area (EPA) as defined by CECC00015 (published by CENELEC) to avoid damage to the assembles.

3. Transducers Monitor must be serviced by Huntleigh Healthcare Ltd. Information is supplied here on the cable and connections for the transducers.

3.1

Ultrasound transducers These multi-crystal, wide-angle ultrasound transducers are used for monitoring fetal heart rate. The ultrasound transducers operate at a frequency of either 2 MHz (colour-coded blue), or 1.5 MHz (colourcoded yellow), and have a maximum ultrasonic power output density of 12mW/cm2 (2 MHz) or 4mW/cm2 (1.5 MHz). The following simple procedures will enable you to test the operation of the ultrasound transducer. The tests are performed with the ultrasound transducer connected to the fetal monitor, and the monitor switched on, as for normal use. Holding the ultrasound transducer in one hand, with the transducer face against the palm, stroke the back of the hand repeatedly with one finger. See diagrams below. Note the audio output, pulse indicator, FHR display and recorder trace on the fetal monitor is in synchronism with the finger movement. Water or gel may be necessary to obtain good contact between the palm and transducer.

The crystal elements in a transducer can be damaged if the transducer is dropped. If one or more crystals have been damaged, this can leave non-receptive areas on the transducer face, reducing the beam coverage. The positions of the crystals behind the transducer face are shown below:

To test the integrity of a suspect transducer: 1.

Squeeze a small amount of Aquasonic gel on to the transducer face over each crystal.

2.

Move the gel tube rapidly up and down over each crystal, keeping the tip of the gel tube in contact with the transducer. Check that you get an audio signal synchronised with the tube movement.

If a transducer problem is confirmed, contact Huntleigh Healthcare Ltd, Service department for advice. 8

3.2

External contractions transducers This transducer is a tocodynamometer whose central section is depressed by the patient’s abdominal muscles during a contraction. To check the operation, connect the external toco transducer to the Team unit. Press the ‘Toco Zero’ pushbutton on the Team unit keypad. The display should show 10% +/- 1%.

3.2.1 Field repair and calibration 1. Remove the stud to release the case back. 2. Refer to the following diagram. Adjust the 20k potentiometer to minimum resistance. + EXCITATION 200R

STRAIN GAUGE OUTPUT STRAIN GAUGE

20K

100R - EXCITATION

3. Set the 200R potentiometer to mid-position. 4. Check the resistance between output and negative excitation and make a note of the reading. 5. Measure the resistance between the output and positive excitation and make a note of the reading. 6. Adjust the 200R potentiometer so that the reading equals that recorded in 3 above.

3.2.2 Test 1. Plug the transducer into the Team unit and press the ‘Toco Zero’ key (10% deflection). 2. With the transducer face-up and horizontal, place a 100g weight on the centre of the plunger. Note he reading on the display. Take the weight off. Adjust the 20k potentiometer slightly. Re- zero the transducer. Place the 100g weight on the button and note the reading. 3. Repeat as above until a reading of 80% ±5% is obtained with the 100g weight. 4. Fit the case back. Fit the membrane. 5. Re-check the transducer with the 100g weight on the button. Make sure the reading is now 70–90%.

3.4

IUP transducer The TeamIP model is designed to make internal IUP measurements with the Intran disposable cathetertransducer. This transducer is connected to the Team unit by the Intran Extension Lead. Transducer sensitivity is 5mV/V/mmHg.

3.5

Patient-held event marker The event marker is operated by a patient operated hand-held push switch. The event mark (a solid sharp triangle) is printed at the top end of the fetal heart rate scale on the chart. When the event marker is operated, the Team unit bleeps and the words “FETAL EVENT NOTED” are displayed for a short time. The audio bleep is selectable in the Setup/Alarm menu.
