Product Safety

Electrical safety

Only trained service personnel are permitted to remove covers and panels from the x-ray equipment .

In the Federal Republic of Germany, the electrical installation of rooms used for medical purposes must conform to the provisions of the VDE Standard 0107. In all other countries, the provisions of the applicable local laws and regulations have priority. The unit is only prepared for solid installation with an all poled separation from the power (IEC 601, Kap. 57.1).

Mechanical safety

It is the responsibility of the operator to ensure safety of patient while the unit is in operation by visual check, proper patient positioning, and use of devices that are provided.

Rest risk:

During proper operation and in case that a first mistake may accur there will be no damage to patient and/or environment.

Danger of injury

The arrows in the illustration show areas which present potential Danger of Injury to operating personnal and patient from the equipment motion.

See next page.

X-Ray Protection.

The unit has no controls with which radiation could be triggerd. Exposure is triggerd only from the radiation-protected location of the generator. The general radiation-protection measures must be observed.

In addition, we recommend the following: 1 Set the tube current as low as possible .

2 Limit the radiation field to the maximum possible extent. 3 Keep as far away as possible. 4 Provide radiation protection for the patient.

07/98 - 5 of 24- 0628 7324

Explosion Protection

This equipment is not designed for use in areas where explosion hazard can take place.

Only skin cleaning agents may be used which form non-explosive mixtures with air.

Interference Suppression

The equipment complies with the EMC-requirements of the guideline 89/336 EWG.

Special board International Electronic Commission (IEC). This unit complies to EN 55011 and the reference value is according EN 55011 Group 1 Class B the international electrotechnical committee (IEC).

Classification of product

The equipment complies to the protection degree of Class 1 and for protection against electric shock Type B.

EC Conformity

The Combi Elevator Tomo-2 to which this declaration relates fulfills the essential requirements for safety of medical electrical equipment and follows the provisions of Medical Device Directive 93/42 EEC part 11 para. 3 according the procedure in

annex II. The CE-Mark is only applicable for the product without X-ray components and Bucky.

The declaration of EC-conformity can be sent to you by request: Write to: Hans Pausch Röntgengerätebau c/o Quality Assurance Sys. Mgr. Postfach 28 60 D-91016 Erlangen Fax #: ..49 9131 99 24 22

Enviroment Condition Surrounding temperatur range 10° C to 40° C Humidity 20% to 80% Atmospheric pressure 700 hPa to 1100 hPa

Disposal of equipment

Legal waste disposal regulations may apply to the disposal of this product. To

avoid causing damage to the environment and personal injury, we recommend

that you contact your Customer Services representative before permanently re-

moving this product from service.

General

Short description

The equipment consists of a motor-driven elevating Bucky table with coordinatus table top and Bucky carriage as well as a floor mounted column stand for X-ray tube unit, collimator and control arm including a totally integrated tomography device for linear blurring movement without mechanical coupling.

The solid, vibration-free table base and the rail stand with column form one unit.

The large and 2.20 m long, floating table top is manually movable and locks electromagnetically. The table top is provided for a maximum patient weight of 136 kg. For fast and easy positioning of the patient, it allows spacious lateral travel: 60 cm to the left, 50 cm to the right and ± 12 cm transversely.

Especially for patient comfort and easy cleaning, the table top offers a scratch-proof surface (Resopal) and trim-covered, smooth profile rails on both sides, which can accept accessories.

The Bucky carriage takes up cassette trays as supplied by any reknowned manufacturer. In longitudinal direction, it is manually moved and electromagnetically locked. The shortest possible OFD of 70 mm guarantees images of superior geometrical proportion. Low radiation absorption by the table top reduces the X-ray amount. The brake of the Bucky is released by a push-button on the operating handle.

The foot treadle along the table base allows the release of the elctromagnetic table top brakes.

The tube stand for the X-ray tube support arm and tube is moved on the rail stand parallel to the longitudinal table axis.

The X-ray tube with collimator and control handle for the tube stand is supported by a lateral arm fixed to the vertical carriage. Vertical movement and rotation of the tube around the longitudinal axis of the lateral arm permit vertical, horizontal or oblique beam projections. Each position is electromagnetically locked.

The X-ray tube with column stand rotates around the vertical column axis and catches mechanically at angles of 0° (basic position), ± 90° (for lateral exposures).

The standard tube support is intended for DIN 6836 flanged plate C. The max. weight of the X-ray tube and collimator must not exceed 40 kg.

For operating there are 3 operating methods from the control panel while pushing the key available:

Table mode - the automatic tube stand - Bucky linkage will adjust automatically the Bucky in their travel range to the middle of the column. Exact positioning of the tube at 0° and ± 90°.

Wall mode - while pushing the key two (adjustable while mounting) SIDs will be motorized positioned while the tube rotates in direction of wall stand. By manual movement of the column is an automaticly stop at the SID`s.
