Technical Specifications - HEINE OPTOTECHNIK DELTA 20 Manual De Usario

• The size of the field of view depends on the size of the image sensor
in the camera. The field of view can vary from one digital camera to
another. (www.heine.com DELTA 20  Camera for DELTA 20)
Brightness Control
• The voltage-regulating electronics of the HEINE DELTA 20
Dermatoscope guarantee constant brightness.
• Pressing one of the two buttons on the instrument (2) will reduce the
brightness by 50% and will turn off 3 of the 6 LED's resulting in lateral
illumination for improved contrast when viewing the pigmented
structure.
• If the image is not bright enough, select a sensitivity of ISO 400 on the
camera.
Contact Plates
• The contact plate (1a) is attached by a bayonet connection. To remove
the contact plate turn it counterclockwise and pull it away from the
Dermatoscope. To attach, reverse the procedure.
• For examination of hard to reach lesions use the small contact plate
(1b) in place of the standard contact plate (1a). (See accessories)
• Both the standard contact plate (1a) and the small contact plate (1b)
can be used for direct visualization and digital photography.
Cleaning /disinfection and sterilization
The plastics used in the instrument do not react with the dermatoscopy
oil. If skin disinfectants are used, the risk of changes to the plastic, such
as discolouration, cannot be completely ruled out. It is recommended
that residues of this disinfectant be removed from the instrument imme-
diately after examination in order to minimize the contact time.
Manual cleaning
• Wipe down the DELTA 20 and the photo adapter with a damp cloth
(soaked in plain water, no added agents).
It must not be rinsed in running water or immersed in water.
• Clean the lens with a lens cleaning cloth.
Cleaning and disinfecting
• Disinfectants must have been approved for use with medical
equipment made of plastic in order to prevent material changes.
• Wipe down the surfaces of the DELTA 20 and photo adapter with
disinfectant.
• If you have used a spray device to disinfect the instrument, remove
any excess agent from the surface in order to prevent the liquid from
entering the instrument. Spray-type disinfection is only permitted with
the contact plate in place.
• The internal light guide must not be treated with solutions containing
alcohol.
• The contact plate can be immersed in disinfectant following removal-
from the instrument.
Important: The instrument must not be immersed in disinfectant.
Sterilization
®
Sterilize the contact plate once it has been removed from the instrument
(steam sterilization: 134 °C/ 5 min.)
