Sterilization

Instructions for sterilization of the Humeca D42 and D80 dermatomes

• Before sterilization the battery-/motor pack inside the handpiece of the dermatome is removed. These parts of the dermatome must never be sterilized!!
• The blade is removed from the dermatome.
• The remaining parts of the dermatome are placed in the autoclave case. This case is designed in such a way that accidental sterilization of the battery/motor cartridge cannot occur. That’s why we strongly advise to always use the special autoclave case. The dermatome is placed in the case with the cover open for optimum cleaning. The sterile funnel is put under the opened cover. The picture below shows how all parts are positioned in the case during washing and sterilization.

• To prevent stains on the surface of the instrument, preferably use pH-neutral disinfecting agents and detergents.
• Steam autoclaving is the preferred sterilization method. A temperature of 134 oC during at least 4 minutes is applied.
• If desired, the instrument can also be gas sterilized (ethyleneoxide).

Additional remarks regarding cleaning and sterilization

The dermatome consists of anodised aluminium and stainless steel. The least damage to coloured and non-coloured anodised aluminium is observed when neutral cleaning agents are used in combination with demineralised water. The quality of water in the cleaning process is of crucial importance. An unfavourable water composition can have a detrimental effect on the materials of surgical instruments. 

Strong alkaline cleaning agents will cause visible changes to the surface of the instrument, like stains and color fading. Hot air drying temperatures higher than 90^oC should be avoided to prevent crazing of the anodized surface. Do not use H₂O₂ (hydrogen peroxide) in the washing process, as it will damage the instrument.  

A recommended procedure for cleaning and sterilization and advisory on cleaning agents to be used is presented in a joint publication of Humeca and Johnson Diversey. It is available on request and can be downloaded from this site at the "Downloads" section.
