Chapter 1: Safety Guide
Chapter 1 Safety Guide NOTE: For Operator and Patient safety, please read through this instruction manual before using the Wallach Fetal2EMR Fetal Monitor.
1.1 Intended Use The Wallach Fetal2EMR (Model F3) Fetal Monitor (hereinafter called Fetal2EMR) is intended for non-invasive monitoring of a single or twin fetuses during antepartum examination, labor and delivery. It is intended to be used only by trained and qualified personnel in antepartum examination rooms, labor and delivery rooms. The Fetal2EMR provides fetal monitoring. It can externally monitor the Fetal Heart Rates (FHRs) using ultrasound and uterine activity via a TOCO transducer. Contraindications: The Fetal2EMR Monitor is not intended for use in intensive care units, operating rooms or for home use.
1.2 Instruction for Safe Operation The Fetal2EMR Monitor is designed to comply with the international safety requirements IEC/EN 60601-1 for medical electrical equipment. It is class I equipment. The Fetal2EMR Monitor operates within specifications at ambient temperatures between +5ºC (+41ºF) and +40ºC (+104ºF). Ambient temperatures that exceed these limits could affect the accuracy of the instrument and cause damage to the modules and circuits. Allow at least 5 cm (2 inches) clearance around the instrument for proper air circulation. You must check that the equipment, cables and transducers do not have visible evidence of damage that may affect patient safety or monitoring capability before use. If damage is evident, replacement is recommended. The Fetal2EMR Monitor must be serviced only by authorized and qualified personnel. Wallach Surgical Devices does not accept responsibility for safety compliance, reliability and performance if modifications or repairs are carried out by unauthorized personnel. Identical replacement parts must be used. Perform periodic safety testing to ensure proper patient safety. This should include leakage current measurement and insulation testing. The recommended testing interval is once per year. The protective categories against electric shock of the patient connections are: -1-
Chapter 1: Safety Guide
1) Ultrasound (FHR1, FHR2)
2) External TOCO
3) Intrauterine Pressure (IUP)
4) Fetal Movement Mark (FM)
This symbol indicates that the electric shock defend grade of this applied part is Type BF.
DECG (Direct Electrocardiography) (Not available in this model) This symbol indicates that the protection against electric shock of this applied part is Type CF. The monitor described in this User Manual is not protected against: a) The effects of defibrillator shocks b) The effects of defibrillator discharge c) The effects of high frequency currents d) The interference of electrosurgery equipment
1.3 Ultrasound Safety Guide Fetal Use The monitor is designed for continuous fetal heart rate monitoring during pregnancy and labor. Clinical interpretation of fetal heart rate traces may be helpful in the diagnoses of fetal and/or maternal problems and complications. Instructions for Use in Minimizing Patient Exposure The acoustic output of the Fetal2EMR Monitor is internally controlled and cannot be varied by the operator in the course of the examination. The duration of exposure is, however, fully under the control of the operator. Mastery of the examination techniques described in the User Manual will facilitate obtaining the maximum amount of diagnostic information with the minimum amount of exposure. Exercising clinical judgment in monitoring low risk patients will avoid unnecessary insonation.
1.4 Safety Precautions WARNING and CAUTION messages must be observed. To avoid the possibility of injury, observe the following precautions during the operation of the instrument.
