DEFIGARD 5000
Organisational Measures V Before using the unit, ensure that an introduction regarding the unit functions and the safety precautions has been provided and understood. V Always store the user guide handy near the device. Make sure that the user guide is always complete and readable. V In addition to this user guide, also legal and other binding regulations for the prevention of accidents and for environment protection must be observed.
1.4
Operational Precautions
Art. no.: 0-48-0060 Rev.: a
V This user guide, and especially these safety notes, must be read and observed. V Danger of electric shock! The energy applied to the patient can be conducted through the patient to other persons, who may suffer a lethal electric shock. For this reason: – Do not touch the patient, the electrodes or other conducting objects during a defibrillation – Do not defibrillate the patient in a puddle of water or on other conducting surfaces. – Switch the device off when it is no longer used. V To grant the patient's safety, it must be ensured that neither the electrodes, including the neutral electrode, nor the patient, or persons touching the patient, come into contact with conducting objects (e.g. RS-232 interface - see Fig. 3.1 on page 15), even if these are earthed. V Changes, including concerning operational behaviour, affecting safety must be immediately reported to the responsible. V Only connect original SCHILLER accessories to the device. V Before switching on, check if the unit's casing and electrode connection are undamaged. V Do not expose the device to great temperature variations over a long period of time. Too great temperature variances can cause condensation water on the unit. If condensing water should occur nevertheless, dry the unit, the defibrillation electrodes and all connections. V Special caution must always be taken on intracardiac application of medical equipment. Especially make sure that no conducting parts connected to the isolated patient input (patient, plug, electrodes, sensor) come into contact with other, earthed conductive objects, as this might short-out the patient's isolation and remove the protection of the isolated input. V Position the device so that there is no possibility of it falling on the patient or floor.

Maintenance V
Art. no.: 0-48-0060 Rev.: a
Accessory equipment connected to the analogue and digital interfaces must be certified according to the respective IEC 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 system standard IEC/EN 60601-1-1. Everyone who connects additional equipment to the signal input part or signal output part configures a medical system, and is therefore responsible that the system complies with the requirements of the valid version of the system standard IEC/EN 60601-1-1. If in doubt, consult the technical service department or your local representative. Magnetic and electrical fields of X-ray equipment, tomographs, radio systems, cellular phones etc. can disturb the unit's function. Avoid using such devices and keep a sufficient distance from them. The charging of energy and the release of the defibrillation impulse can disturb other devices. Check these devices before their further use. Sensors and devices that are not defibrillation proof must be disconnected from the patient before a shock is triggered. If the patient has a pacemaker implanted, do not position the electrode directly onto the pacemaker. Check the pacemaker after the defibrillation. The input terminals of the DEFIGARD® 5000 are protected against the influences of high-frequency electrosurgical equipment. Nevertheless, precautions must be observed when high-frequency devices are used at the same time. To reduce the risk of burns in the case of a failure of the neutral HF electrode, a distance of at least 15 cm must always be kept between the defibrillation electrodes and the HF surgical electrodes. If in doubt, disconnect the electrodes and sensors from the unit during use of a HF surgical device.
V V V V
Danger of electric shock! Do not open the device. No serviceable parts inside. Refer servicing to qualified personnel only. Before cleaning, switch the unit off and remove the battery. Do not use high temperature sterilisation processes (such as autoclaving). Do not use e-beam or gamma radiation sterilisation. Do not use aggressive or abrasive cleaners. Do not, under any circumstances, immerse the device or cable assemblies in liquid.
