Safety Test
A safety test is to be completed within the framework of the annual inspection by qualified personnel. 1 .
Perform a visual inspection of the device. Of particular importance is:
•
The fuses are in accordance with the specifications of the manufacturer. The text and labels on the device are legible. The mechanical condition of the device allows for safe use. No safety relevant contamination of the device exists.
• • • 2.
3.
4.
2-2
Perform the measurement of the leakage current in accordance with DIN EN 60601-1 / IEC 601-1. Perform the measurement of the protective conductor resistance in accordance with DIN EN 60601-1 / IEC 601-1. The protective conductor resistance should be measured with the power cord connected. The maximum value should reflect 0.2 Ω. Perform the measurement of the insulation (resistance) with 500-700 V DC. The minimum value should reflect 50 MΩ. The measurement of rigging strength should not be performed using high voltage.
Deficiencies Caused by Disinfectants, Ultra Violet Rays and Others
Since disinfectants used in the operating room as well as nascent ozone from ultra violet radiators can change the surface of the device and the following checks should be performed: Cabling: Check for correct condition and location of the cables. If insufficient insulation, fragility and faulty contacts are suspected, the corresponding cables should be replaced. Electronic PC boards: If the PC boards show corrosion or other deficiencies at the contacts or soldered joints they should be replaced for safety reasons (see chap. directions for components interchange). Front panel and the cover: Check for the correct condition of the front panel and cover. Make sure that there are no deficiencies that influence the operation or safety. Check the correct functions of the digital displays, control panels and LEDs.
Tubing Fluid may penetrate the device through the insufflation tube connection. You can recognize this from the residue that appears in the area of the tube spots in the transparent tubes. Every part that has come into contact with fluid must be replaced. If the pressure sensors come into contact with fluid, you must replace the corresponding PCB.
