Oxford Instruments Medical has been certified by Lloyd's Register Quality Assurance as an approved medical devices manufacturer as meeting the requirements of BS EN ISO 9001, BS EN 46001 and the Medical Devices Directive (93/42/EEC). The Sonicaid FM800 range has been independently tested and successfully approved to the following medical safety standards EN 60601-1, EN60601-1-2, IEC 601-1, IEC 601-1-2, UL 2601-1, CAN/CSA-C22.2 No. 601.1-M90, JIS T1001, JIS T1002. The Sonicaid FM800 range is CE Marked in accordance with the European Council Directive (93/42/EEC) concerning medical devices. The Sonicaid FM800 range also bears the ETL Listing Mark, which is a nationally Recognised Testing Laboratory (NRTL Mark) in United States and Canada.

fåëí~ää~íáçå=`çãéäá~åÅÉ When connecting the FM800 Monitor to external equipment: 1

Non-medical equipment must comply with the relevant IEC or ISO safety standard. For Information Technology equipment, this standard is IEC950/EN60950.

2

Medical equipment must comply with IEC601-1/EN60601-1.

3

The configured system must comply with the system standard IEC601-11/EN60601-1-1.

4

If non-medical equipment (e.g. the PC or printer) with enclosure leakage currents greater than those allowed by IEC601-1/EN60601-1 is to be used in the patient environment (within 1.5m of the patient), you must bring the enclosure leakage currents within the limits laid down by IEC601-1/EN60601-1. This may be done by using a suitable isolating transformer which meets the IEC601-1/EN60601-1 standards.

5

Anybody who connects additional equipment to signal input or signal output parts of the system is configuring a medical system, and is therefore responsible for ensuring that the system complies with IEC601-1-1/EN60601-1-1. If you are in any doubt whether your system does comply, consult the technical service department of your local Oxford Instruments representative.

The connection of extra equipment to the patient or FM800 could lead to the summation of leakage currents. In such circumstances the user must ensure that safe leakage currents are not exceeded.

`~äáÄê~íáçå

There is no special procedure for calibrating FM800.

t~êåáåÖ=çå=Ä~ííÉêó=~åÇ=ë~ÑÉ=Çáëéçë~ä The Digital board is fitted with a lithium backup battery. Should this battery need replacing it MUST be disposed of as per local regulations. The lithium battery MUST only be replaced by a battery of the same type. (SL350) Size ½ AA Fire , Explosion and server burn hazard . Do not recharge. Do not disassemble. Do not heat above 100 oC or incinerate Do not expose contents to water.

ix

bäÉÅíêçã~ÖåÉíáÅ=`çãé~íáÄáäáíó Make sure the environment in which FM800 is installed is not subject to strong sources of electromagnetic interference (e.g. radio transmitters, mobile phones). This equipment generates and uses radio frequency energy. If not installed and used properly, in strict accordance with the manufacturer's instructions, it may cause or be subject to interference. Type-tested in a fully configured system, it has been found to comply with IEC601-12/EN60601-1-2, the standard intended to provide reasonable protection against such interference. Whether the equipment causes interference may be determined by turning the equipment off and on. If it does cause or is affected by interference, one or more of the following measures may correct the interference: •

Reorienting the equipment

•

Relocating the equipment with respect to the source of interference

•

Moving the equipment away from the device with which it is interfering

•

Plugging the equipment into a different outlet so that the devices are on different branch circuits

Adding accessories or components to a system, or modifying a medical device or system, may degrade the immunity performance. Consult qualified personnel before making changes to the system configuration.

Chapter 1 General Information

NKO mêçÇìÅí=aÉëÅêáéíáçå The pçåáÅ~áÇFM800 range of monitors is designed to provide flexible solutions for intrapartum monitoring needs, both for today and in the future. A choice of models allows for the selection of the facilities required, from standard intrapartum fetal monitoring capabilities to high-risk fetal or maternal care. Because the range is modular, each monitor can be upgraded as and when the need arises.

NKOKN pçåáÅ~áÇcjUOM Designed to help with the management and care of all pregnancies, where comprehensive and adaptable fetal monitoring facilities are needed, the pçåáÅ~áÇFM820 offers twin ultrasound, separate fetal and Maternal ECG channels, external and internal uterine activity monitoring, and maternally sensed fetal movements.

NKOKO pçåáÅ~áÇcjUPM To closely monitor the mother as well as the fetus, the pçåáÅ~áÇFM830 is a fully integrated fetal/maternal monitor with the facilities for simultaneous monitoring of pulse oximetry, blood pressure and temperature without the need for additional stand-alone devices.

NKOKP pçåáÅ~áÇcjUQM Fetal pulse oximetry provides direct measurement of fetal oxygen saturation during labour and delivery. The pçåáÅ~áÇFM840 integrates Nellcor Puritan BennettTM technology to provide the clinician with this additional parameter for assessing the fetal condition.

NKOKQ pçåáÅ~áÇcjURM The pçåáÅ~áÇFM850 is the complete solution for high-risk intrapartum cases combining intrapartum fetal monitoring, maternal vital signs and fetal pulse oximetry facilities. Note FM840 and FM850 are not currently available for sale in the USA.
