H&O Equipments CryoPen User Manual page 7

IMPORTANT NOTICE:
• When used correctly, the device does not come into contact with the lesion nor the skin.
• When used normally, there is no need to perform any maintenance, cleaning or disinfection.
• Never clean the thread of frontend and backend. The existing coating should be protected.
• Should the applicator touch the patient in case of misuse, the applicator can be cleaned (autoclaved: 134 °C/273 °F - 4 min
or 121 °C/250 °F – 20 min) and disinfected (use a non-corrosive disinfecting solution, follow the disinfecting solution
manufacturer's recommendations with regards to the concentration and time of application).
• Always gently manipulate all components of CryoPen instruments. Never use more than gentle hand force. Never use pliers
or other tools to manipulate the instrument.
• Please ensure to only use the cartridges and filter/openers supplied from H&O Equipments nv/sa. Any other cartridges and
filter/openers would damage the instrument.
• Incorrect placement of the filter/opener device into the loading cavity will cause irreversible damage to the instrument.
• Residual foreign matters in the loading cavity while placing a new filter/opener can cause instrument failure.
• When loaded, the instrument is under high pressure. Any change to the construction of the instrument may cause a potential risk.
• Never put your hand on the gas release opening at the end of the backend while removing the cartridge!
• All external parts can be wiped with a cloth soaked in any noncorrosive disinfecting solution. Never immerse the entire
instrument in a disinfecting solution.
• The applicators must be kept away from dust and the cartridges must be kept away from high temperatures (max
50°C/122°F). Leave the applicator cap on when not in use.
• The CryoPen should be handled with care. When storing the instrument with a loaded cartridge in its case, position the CryoPen
in such a way that the trigger cannot be pressed when closing the lid of the case. This would cause undesired gas flow.
• CryoPen instruments are intended for professional use only.
• The N O cartridges contain both a liquid and a gaseous phase in balance. The proportion of each phase depends on the room

temperature which affects the output flow. The best performances are achieved when the cartridge temperature is between
19°C and 22°C (66°F and 72°F). Lower and higher temperatures will give different values of pressure and density of the
cryogen. Over 25°C/77°F, the quantity of liquefied N
• Empty cartridges should be discarded as metal scrap.
O in the CryoPen jet will decrease.
