Hygienic manufacturing and development / scanning of X-rays

 

It is very important to keep all equipment for radiographs and for the process of imaging clean. This applies to both the X-ray tube, the timer button, computers and scanners, as well as to traditional development machines.

 

For the manufacture of the radiographs, strict hand hygiene must be applied when manipulating the X-ray tube. During setting, not only the X-ray head but also one of the folding arms is moved. It is therefore never possible to find out where exactly the X-ray tube and the articulated arms are contaminated. This means that the entire X-ray tube, including the entire articulated arm, should be disinfected after a single shot.

 

The rule here also applies: cleaning is better than cleaning!

 

After putting the photo in the mouth with adjusting equipment, proper hygiene (shoe) is taken care of before (!) Grasping the X-ray tube.

 

Aiming the tube and printing the timer is done with clean hands. The X-ray tube is then turned away to the fixed parking position. The photo is then taken out of the mouth by grasping the adjustment equipment and placing the photo on the dirty work field.

 

For a follow-up recording, the X-ray tube is moved around the head of the patient in the direction where the next X-ray should be taken. When placing the image carrier for the next image, one of the hands is usually dirty again. Then apply good hand (shoe) hygiene again before the X-ray tube is aimed and can be printed.

 

After that the photos can be processed as described below.

 

CCD-sensor

  • Pre-setting the computer to receive the recording must be done with a clean hand (shoe)!
  • After recording (s), grasp the sensor cable with a clean hand, just below the protective cover.
  • Pull the protective cover of the sensor with the other (dirty) hand and throw it directly into a handsfree trash can (or temporarily in the sink).
  • Carefully place the sensor on a clean work area.
  • Apply hand hygiene.
  • Place a clean sleeve around the sensor and hang the sensor back in the holder for the next recording. If the sensor is in the treatment room and aerosol can descend on the sensor, it is wise to apply a new sleeve or use double sleeves only when the next use. The outer protective sleeve can then easily be removed at the time of use.

 

Analog x-rays with protective film

  • Let the photo fall from the protective film hands free on a clean surface.
  • Deposit the case directly into a hands-free trash can.
  • Pull out the gloves and take the photos to the development machine.
  • Enter the photos in the development machine.

 

Drop the photo onto a clean work area, remove gloves, disinfect the hands and develop the photo

 

Analogue photos without protective film and phosphor plates

  • Rinse the image carriers under the tap after recording and / or clean them with a wet disinfectant wipe.
  • Let the cleaned photos fall on a clean work area.
  • Pull out the gloves and disinfect the hands.
  • Take the photos of the clean work area and transport them to the scanner or the development machine.
  • Process the photos according to instructions.

 

A separate method is possible for the processing of phosphor plates using cardboard inner sleeves as well. The case of the phosphor plate is torn open by the dentist and the image is handled by the assistant with a clean hand, directly from the packaging.

 

Hands-free scanning of phosphor plate, see text for explanation

 

  • Transport to the scanner is now immediately possible without additional cleaning. The image is inserted into the scanner from the cardboard box and then 'collected' again in the cardboard box.
  • After scanning the phosphor plates, a new cover can be applied immediately or immediately before the next use.
