  • Page 3: Introduction And Indications For Use

    1. INTRODUCTION AND INDICATIONS FOR USE ZEN-X / ZEN-Xi are digital intraoral sensors intended for acquiring intraoral digital images when exposed to X-rays, for diagnostic radiographic examination of the human dentition (teeth, maxillary area and oral structures). The produced digital images are automatically transmitted via digital connection to a PC.
  • Page 4: General Warnings

    In order to use the ZEN-X / ZEN-Xi sensor, software for capturing and saving the images is needed that is not part of the ZEN-X / ZEN-Xi sensor. Consult the relative manual for information about installation and use of the image management software.
  • Page 5: Stylistic Conventions

    The sensor has been manufactured in compliance with the IEC standards on safety of electro-medical devices of similar type and particularly with the following technical standards: IEC 60601-1:2005 + A1:2012 - General requirements for basic safety and essential performance. IEC 60601-1-2:2014 (4th Ed.) - General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests.

    (“drivers” installed in computer and “firmware” in the devices) are compatible with other commercial devices. Therefore use of the ZEN-X / ZEN-Xi sensor and relevant software in conjunction with other commercial devices is not assured or recommended.
  • Page 7: General Safety Warnings

    necessary to install the sensor with longer cables, a USB repeater must be compulsorily installed every ® 4.5m, and for a maximum of three cable sections (two repeaters). WARNING: The sensor used to capture images is fragile and bothered by electrostatic discharges.

  • Page 13: Protection Against Radiation

    1.6.6. PROTECTION AGAINST RADIATION The digital sensor must be used together with an intraoral x-ray system. As such, the system exposes the patient and the operators to the risks deriving from radiation. It must be used in compliance with the safety regulations set out in the radiation protection standards in force in the country of use.
  • Page 14 Centre for any reason, completely disinfect the outside of the apparatus with a specific product (see paragraph “Cleaning and disinfecting”) and send it back preferably in its original box. No electronic parts of the sensor require maintenance. If the sensor or interface casings are opened to reach the circuits inside, devices may be broken, the protective means for electric safety may be disabled and the warranty will become null and void.
  • Page 15: Cleaning And Disinfection

    Scrapping At the end of its lifetime, dispose of the device in accordance with the regulations in force. It is also advisable to disinfect all the external parts of the device before disposal and to separate the materials for differentiated waste collection.

  • Page 17: Cleaning And Disinfection Of The Sensor And Its Power Cable

    Cleaning and disinfecting instructions. Clean and disinfect with disposable non-abrasive paper (avoid using recycled paper) or sterile gauze. Do not use sponge cloths or, in any case, any material that can be reused. WARNING: In order to clean equipment connected to the power mains, shut off the devices and disconnect the power supply from the outlet before attempting to clean and disinfect the outside.
  • Page 18: Applied Parts

    WARNING: Disposable hygienic protections are the main protection means against cross contamination between patients. In order to prevent the transmission of infectious diseases between patients, it is essential to always use disposable protections. Disposable protections are class I medical equipment and cannot be replaced with other protections having lower specifications.

    Take X-ray picture. The image will appear on the computer screen after a few seconds, and, if enabled, it can be seen in the MyRay® Monitor preview window and right-hand column next to the main window. No other steps are required to capture further images after the first x-ray picture has been taken.
  • Page 25 A green box indicates that the sensor is enabled and ready to acquire an image. Make an acquisition only when the sensor is in this status. The software also indicates the remaining time before the sensor goes into stand-by mode. WARNING: Always check system status before attempting to take x-rays on a patient.

    If edentulous areas are irradiated, the device may provide images that are too blackened in the missing areas of the irradiated radiographic subject. In these cases, reduce the time indicated in the table by about 1/4. The best results are achieved with a high frequency generator with square collimator and 30cm focus-to-skin distance (refer to the relevant table).
