1 Introduction

1Introduction

1.1GENERAL

INSTRUMENTARIUM DENTAL® Orthopantomograph® OP200 panoramic unit is a software controlled diagnostic panoramic dental x- ray equipment for producing high quality images of dentition, TM-joints and skull. Anatomical details will be displayed on the film magnified nominally by 30%.

The Orthopantomograph® OP200 can perform the following procedures:

•Standard panoramic exposure

•Pediatric panoramic exposure

•Wide arch panoramic exposure

•Ortho Zone enhanced panoramic exposure

•Orthogonal panoramic exposure

•TMJ, lateral projection or

•Ortho TMJ axial corrected lateral projection (optional)

•TMJ, lateral projection jaw closed and open

•TMJ, PA projection

•TMJ, lateral and PA projection

•Maxillary sinus

Your Orthopantomograph® OP200, model OP200 OT or OP200 CR, can be field upgraded at a later time to the Orthoceph® OC200 model. With this addition, high quality cephalometric exposures can also be made.

NOTE!

OP200 must be installed according to the OP200 installation & Adjustments manual by a qualified technician. Only trained personnel should be allowed to operate OP200.

In addition to the above mentioned procedures Orthoceph® OC200 can perform the following cephalometric procedures:

•Lateral view

•Postero-anterior and Antero-posterior views

•Oblique projections

•Townes, Waters, Caldwell, SMV, Carpus

Orthopantomograph® OP200 or Orthoceph® OC200 can also be field upgraded to the OP/OC200 OT model. OP200 with the Ortho Trans option can do the following linear tomographic procedures:

•Maxillary imaging in longitudinal and transversal views

•Mandible imaging in longitudinal and transversal views

Digital imaging is possible with OP200 D and OC200 D models or by using phosphor image plates with OP200 CR, OC200 CR, OP200 OT/ CR and OC200 OT/CR models.

1.4OPTIONS, ACCESSORIES AND MANUALS

The options are listed in the appendices. The accessories are listed in sections 2.5 and 2.6. All standard items and approved accessories are suitable for use within the patient environment.

WARNING!

This product itself complies IEC601-1-1 medical safety standard but in order to the system incorporating also a PC to comply the standard, EITHER the PC has to be a medical PC OR the PC has to be located over 1,5 meters apart from the OP/OC200 unit. The installer and the user of the system shall confirm that at least one of the above requirements is fulfilled. A PC is a medical one if it complies IEC 6011standard and that is indicated in the accompanying documents of the PC.

NOTE!

To maintain safe and correct functioning of OP200, only the approved accessories may be used.

CAUTION!

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Following manuals and documents are shipped with the OP200:

1.5RADIATION PROTECTION GUIDELINES

X-ray equipment may cause injury if used improperly. The instructions contained in this manual must be read and followed when operating the Orthopantomograph® OP200. All government and local regulations pertaining to radiation safety must be observed.

NOTE!

For USA: Many provisions of these regulations are based on recommendations of the National Council on Radiation Protection and Measurements. Recommendations for dental x-ray protection are published in NCRP Report #35 available from NCRP Publications, 7910 Woodmont Avenue, Suite 1016, Bethesda, MD 20814.

Personal radiation monitoring and protective devices are available and recommended for staff members. It is also recommended to provide the patient with a protective apron. Consult the physician before taking images of pregnant patients.

WARNING!

Orthopantomograph® OP200 must not be used in rooms where an explosion hazard exists. Equipment not suitable for use in the presence of flammable mixtures.

OP200 with radiation protection in accordance with IEC601-1-3:1994.

1.5.1Protection by distance

In all examinations the user of the x-ray equipment should wear protective clothing. The operator does not need to be close to the patient during normal use. The protection against stray radiation can be achieved by using the hand switch not less than 2 m (7 ft.) from the focal spot and the x-ray beam. Operator should maintain visible contact with the patient and technique factors. This allows immediate termination of radiation by the release of the exposure button in the event of a malfunction or disturbance.

1.5.3Control from a protected area

The operator does not need to be close to the patient during normal use. Control panel hand switch or optional remote hand switch can be used from an area protected from the x-ray beam. The fully extended spiral cable length of the control panel hand switch is approx. 4 m / 13 ft. The cable length of the remote hand switch (part #69961) is approximately

10 m / 32 ft.

1 Introduction

1.5.4Emergency Stop Switch

In case of malfunction of the exposure button release or other protective devices of the unit, an emergency stop switch is provided on the right side of the unit so that the patient can reach it. If the emergency stop switch is pressed during the exposure, the exposure is terminated immediately and the x-ray unit is completely stopped. The exposure interrupted by emergency stop switch, cannot be continued later, but has to be retaken from the beginning.

3.1CARE INSTRUCTIONS

X-ray devices are sophisticated electronic products including advanced technologies. As such, they have to be handled with a high degree of care. This document gives the care instructions applicable to the Orthopantomograph® panoramic and cephalostat units.

As a standard recommendation, clean the unit regularly using nonagressive, mild, commercially available cleaning agents.

3.2CLEANING RECOMMENDATIONS

The unit should be cleaned after every usage between the patients. Items and surfaces that are not given special instructions for cleaning, disinfecting and sterilizing, can be cleaned with soft cloth moistured with disinfective after every usage.

WARNING!

Always disconnect OP200 from mains or switch off the power prior to cleaning or disinfecting the unit.

CAUTION!

Do not allow water or other cleaning liquids to enter the unit interior since these may cause short-circuits or corrosion.

3.2.1Cleaning

The purpose of cleaning and rinsing is to remove all adherent visible soil (eg. blood, protein substances and other debris), to reduce the number of particulate and micro-organisms, and to reduce the amount of pyrogenic and antigenic material.

Use a cloth moistened in cool-to-lukewarm, soapy water to clean the unit, and prevent coagulation and thus faciliate the removal of protein substances. Then wipe with a cloth moistened in clear water. Mild detergent solution can be used. Use cleaners or solvents, which are listed as allowed cleaning agents below. If you are uncertain of the nature of cleaning agent, do not use it.
