CLEANING AND DISINFECTION:

CARE AND MAINTENANCE

Care and maintenance are vital to keep the attachments in good condition and fully functional!

Causes of corrosion with stainless steel used for instruments.

Corrosion is damage or wear that can be caused by a chemical reaction, e.g. due to:

1.) Damaged surfaces

2.) The effect of surgical exudates: blood, suppuration or bodily secretions in prolonged contact with instruments.

3.) Excessive exposure to certain solutions: saline and iodine solutions, chloride and strong acids, alkaline solutions and incorrectly

used disinfectants

4.) Poor water quality when cleaning, steam-sterilising or rinsing instruments and attachments: e.g. due to rusty water pipes or

pene tration of rust and metal particles into steam sterilisers.

5.) Inadequate maintenance of instruments and accessories: If rust forms, it may be transferred to other instruments and

attachments (avoid contact at all costs because it is very dangerous for sterilisation).

Constant use of instruments and attachments constitutes natural wear, which shortens the service life correspondingly.

Instruments and attachments that are used often should be replaced at regular intervals.

MEASURES TO PREVENT CORROSION:

1.) Careful laying out of correctly packaged and sterilised instruments before the operation: selection according to the type of i n -

tervention. Always ensure that the outer packaging is intact and the expiry date has not elapsed.

2.) Check the sterilisation indicator inside the tray to ensure that the contents have been sterilised.

3.) Arrange the instruments and attachments according to the sequence of use during the operation: if any instruments are not

needed, leave them in the tray; only prepare instruments and attachments a short time before the operation.

4.) Remove blood and other exudates from instruments and attachments during the operation: replace instruments and attach-

ments. in their assigned place after use.

5.) Flush through cannulated instruments to prevent blood and bone powder from drying on.

6.) Use Ringer‘s lactate solution or saline solution to clean instruments and accessories, but do not immerse them in solutions.

7.) Start cleaning immediately after the operation: instruments and attachments used during the operation are regarded as conta-

minated. Instruments used on patients with possible infections must be similarly disposed of; wipe off any blood, bone powder and

tissue remnants.

8.) Clean instruments in a designated place within the surgery department. If the instruments are sent directly to the central ste-

rilisation area, rst cover them up to prevent any risk of contamination for staff or the environment. Wear protective clothing when

disposing of contaminated instruments and attachments!

DISMANTLING FOR CLEANING:

Instruments and attachments with removable parts should be dismantled. Keep all screws, nuts, bolts and other small parts together,

ensuring it is clear which instrument they belong to. The persons responsible for dismantling and reassembling instruments should

be appropriately trained. Clean the individual parts to remove any remaining blood or bone powder and prevent drying on during

sterilisation and consequent irreparable damage.

DISINFECTION:

When using chemical disinfectants, the manufacturer’s instructions must be strictly followed: but always dilute solutions before use.

For thermal disinfection with hot water, the water must be free of foreign bodies.

Please note: Instruments and attachments made of anodized aluminium should not come into contact with certain disinfectant so-

lutions or cleaning agents, so always check the solution before use to avoid subjecting the metal to a chemical reaction.

CLEANING:

Whether cleaning mechanically or manually, check carefully which cleaning agent is used with which

method. Always observe the instructions for dilution and use. Recommended pH: between 7.0 and 8.5.
