Patient Monitor User Manual

Indication for Use and Safety Guidance

Chapter 1 Indication for Use and Safety Guidance 1.1 Indication for Use M80: The monitor monitors parameters such as ECG (3-lead, 5-lead, 12-lead selectable), Respiration (RESP), Functional arterial oxygen saturation (SpO2), Invasive or noninvasive blood pressure (2/4 channels IBP NIBP), Cardiac Output (C.O.), Temperature (dual-TEMP), Expired CO2 and Anesthetic gas (AG). The monitor is equipped with alarms that indicate system faults (such as loose or defective electrodes), physiologic parameters that have exceeded the limits set by the operator, or both. M50: The monitor monitors parameters such as ECG (3-lead, 5-lead selectable), Respiration (RESP), Functional arterial oxygen saturation (SpO2), Invasive or noninvasive blood pressure (dual-IBP, NIBP), Temperature (dual-TEMP), Expired CO2 and Quick Temperature (Quick TEMP). The monitor is equipped with alarms that indicate system faults (such as loose or defective electrodes), physiologic parameters that have exceeded the limits set by the operator, or both. The arrhythmia detection and ST Segment analysis are not intended for neonatal patients.

1.2 Safety Guidance WARNING 1 Before using the device, the equipment, patient cable and electrodes etc. should be checked. Replacement should be taken if there is any evident defect or signs of aging which may impair the safety or performance. 2 Medical technical equipment such as these monitor/monitoring system must only be used by persons who have received adequate training in the use of such equipment and who are capable of applying it properly. 3 EXPLOSION HAZARD-Do not use the device in a flammable atmosphere where concentrations of flammable anesthetics or other materials may occur. 4 SHOCK HAZARD-The power receptacle must be a three-wire grounded outlet. A hospital grade outlet is required. Never adapt the three-prong plug from the monitor to fit a two-slot outlet. 5 Extreme care must be exercised when applying medical electrical equipment. Many parts of the human/machine circuit are conductive, such as the patient, connectors, electrodes, transducers. It is very important that these conductive parts do not come into contact with other grounded, conductive parts when connected to the isolated patient input of the device. Such contact would bridge the patient's isolation and cancel the protection provided by the isolated input. In particular, there must be no contact of the neutral electrode and ground.

WARNING 6 Magnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason make sure that all external devices operated in the vicinity of the monitor comply with the relevant EMC requirements. X-ray equipment or MRI devices are a possible source of interference as they may emit higher levels of electromagnetic radiation. 7 Route all cables away from patient’s throat to avoid possible strangulation. 8 Devices connecting with monitor should be equipotential. 9 Accessory equipment connected to the analog and digital interfaces must be certified according to the respective IEC/EN standards (e.g. IEC/EN 60950 for data processing equipment and IEC/EN 60601-1 for medical equipment). Furthermore all configurations shall comply with the valid version of the standard IEC/EN 60601-1-1. Therefore anybody, who connects additional equipment to the signal input or output connector to configure a medical system, must make sure that it complies with the requirements of the valid version of the system standard IEC/EN60601-1-1. If in doubt, consult our technical service department or your local distributor. 10 Only patient cable and other accessories supplied by EDAN can be used. Or else, the performance and electric shock protection can not be guaranteed, and the patient may be injuried. 11 Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a low level or off during patient monitoring may result in a hazard to the patient. Remember that the most reliable method of patient monitoring combines close personal surveillance with correct operation of monitoring equipment. 12 When interfacing with other equipment, a test for leakage current must be performed by qualified biomedical engineering personnel before using with patients. 13 During monitoring, if the power supply is off and there is no battery for standby, the monitor will be off, and only the patient information and alarm settings can be saved. After reconnecting the power supply, the user should turn on the monitor for monitoring. 14 Keep away from fire immediately when leakage or foul odor is detected. 15 The device and accessories are to be disposed of according to local regulations after their useful lives. Alternatively, they can be returned to the dealer or the manufacturer for recycling or proper disposal. Batteries are hazardous waste. Do NOT dispose them together with house-hold garbage. At the end of their life hand the batteries over to the applicable collection points for the recycling of waste batteries. For more detailed information about recycling of this product or battery, please contact your local Civic Office, or the shop where you purchased the product. 16 Dispose of the package material, observing the waste control regulations and keeping it out of children’s reach. 17 After defibrillation, the screen display recovers within 10 seconds if the correct electrodes are used and applied based on the manufacturers’ instructions. 18 This equipment is not intended for family usage.

CAUTION 1 Electromagnetic Interference - Ensure that the environment in which the patient monitor is installed is not subject to any sources of strong electromagnetic interference, such as radio transmitters, mobile telephones, etc. 2 Keep the environment clean. Avoid vibration. Keep it far away from corrosive medicine, dust area, high temperature and humid environment. 3 Do not immerse transducers in liquid. When using solutions, use sterile wipes to avoid pouring fluids directly on the transducer. 4 Do not use autoclave or gas to sterilize the monitor, recorder or any accessories. 5 The device and reusable accessories could be sent back to the manufacturer for recycling or proper disposal after their useful lives. 6 Disposable devices are intended for single use only. They should not be reused as performance could degrade or contamination could occur. 7 Remove a battery whose life cycle has expired from the monitor immediately. 8 Avoid liquid splash on the device. The temperature must be kept between 5°C and 40°C while working. And it should be kept between -20°C and 55°C during transportation and storage. 9 To ensure patient safety, use only parts and accessories manufactured or recommended by EDAN. 10 Federal law restricts this device to sale by or on the order of a physician.

NOTE： 1 Position the device in a location where the operator can easily see the screen and access the operating controls. 2 The monitor can only be used on one patient at a time. 3 If the monitor gets damp or liquid pours on the monitor, please contact the service personnel of EDAN. 4 This monitor is not a device for treatment purposes. 5 The pictures and interfaces in this manual are for reference only. 6 Regular preventive maintenance should be carried out every two years. You are responsible for any requirements specific to your country. 7 The monitor may not be compatible with all models of USB flash drives. Use the USB flash drives that are recommended by EDAN.
