Intended use

This washer-disinfector can be used to clean, rinse, intermediate-level thermally disinfect, and dry a wide range of reusable medical devices in hospitals, surgery centers, and clinics. Always follow the surgical instrument manufacturer’s instructions for machine-based cleaning. This washer-disinfector provides an automated process for the initial steps of cleaning and intermediate-level disinfection of re-useable surgical instruments prior to sterilization G 7899 is designed for applications such as:

General Surgical Instruments

^ Reusable, hard-surfaced surgical

instruments such as scissors, forceps, etc.

^ Stainless steel lumened instruments.

These can be processed but must be connected to Miele injection ports according to loading instructions provided with the specific Miele accessory.

Minimally Invasive Surgical (MIS) Instruments

. The

Microsurgical Instruments

Such as instruments used in eye

surgery

When processing instruments in the Miele washer-disinfector you must:

Follow the instrument manufacturer’s

instructions for cleaning and disinfection. Instruments must be disassembled according to the manufacturer’s instructions

Follow Miele instructions for proper

loading (included with specific accessories and in the “applications” section of this manual). Proper instrument loading and connection of lumened instruments to injection ports is required

^ This washer-disinfector is intended to

provide the initial step in reprocessing of soiled, re-usable medical devices. Any devices that

contact blood or compromised tissues must be sterilized prior to re-use following industry best practices such as AAMI ST79.

Rigid endoscopes

Note: The G 7899 is NOT intended for reprocessing of flexible endoscopes of any kind.

Containers and utensils

Such as kidney dishes, sterilization containers, trays, etc.

Intended use

Processing instruments by machine achieves reproducible results with less opportunity for human error when compared with to manual cleaning. Thermal disinfection can be carried out using the Vario TD program which meets the parameters to achieve intermediate-level disinfection.

The cleaning program as well as chemical agents must be chosen according to the type of soil and load being processed.

Medical devices are best processed using the Vario TD program. The final result will be instruments that are clean, free of residue, and ready for subsequent sterilization. Only then can the instruments be safely used.

The use of a suitable load carrier (basket, module, insert, etc.) is important to ensure the adequate cleaning of the load. Examples are given in the “Applications” section.

The washer-disinfector can be programmed to perform the final rinse with tap water, or with purified water of a quality to suit the application (de-ionized, de-mineralized, reverse osmosis (RO), distilled). We recommend the use of purified water.

All instruments and accessories cleaned in the washer-disinfector (with the exception of non-critical items) must be sterilized before use.

Water softener

Filling the salt reservoir

Only use reactivation salt with granules of approx.1-4mm.Donotuseother types of salt such as cooking salt, agricultural grade or road salt. These may contain insoluble additives which can impair the functioning of the water softener. If in doubt please contact Miele. Reactivation salt can be ordered directly from Miele.

The salt reservoir holds approx.

2.5 kg of salt.

Inadvertently filling the salt

reservoir with cleaning agent will damage the water softener. Before filling the salt reservoir make sure that there is no fluid covering the salt reservoir cap.

Remove the bottom basket from the

machine.

Unscrew the salt reservoir cap.

Before filling the salt reservoir with reactivation salt for the first time, you will have to fill the reservoir with approx. 2/3 gal (2.5 liters) of clean water to enable the salt to dissolve. Once the machine has been used, this will no longer be necessary.

Place the provided funnel in position.

Fill carefully with salt.

As it is poured in, displaced water will run out.

Remove the funnel and wipe any

residual salt off the seal and the screw threads.

^ Screw the cap back on firmly.

^ Run the “Rinse” program to remove

any traces of salt from the cabinet.

The program sequence may be delayed for a few minutes after the start of the “Rinse” program. This is normal as the water softener is being reactivated.

Water softener

Add salt indicator

Reactivation will take place automatically when needed prior to the start of your selected program. The “Recharging” indicator lamp a will be lit during this process.

^ Add salt when the “Recharge

Softener” indicator b lights up.

Applications

This washer-disinfector normally requires a top and bottom basket. Various inserts and special baskets are available for a wide variety of instruments and utensils.

Select baskets and inserts which are appropriate for the application.

Applications and loading examples are given on the following pages.

Before starting a program, visually check the following:

– Is everything correctly

loaded/connected?

– Are the lumen or necks of hollow

instruments positioned so that water can access them unhindered?

– Are the spray arms clean and do

they freely rotate?

– Are the filters clean? Remove any

coarse soils and clean them if necessary.

–

Is the adapter connecting the water supply to the spray arms/jets connected correctly?

–

Are all chemical containers sufficiently filled?

At the end of each program:

Visually check the load for

–

cleanliness.

Check that all hollow shafted

–

instruments are still securely positioned on their jets.

Any hollow instruments that have

become disconnected from their adapters during processing must be processed again.

Check that the lumen of hollow

–

instruments are free of obstruction.

– Check that jets and connectors are

securely in position in the baskets or inserts.

Verification testing

For verification of the cleaning process, periodic testing as outlined in current best practices documents such as AAMI ST79 is highly recommended. While Miele washers automatically monitor critical parameters such as time, temperature and dispensing, periodic verification to ensure proper soil removal should be part of your quality and safety program.

Miele also offers process documentation to support your periodic verification.

Loading the machine

For proper cleaning, arrange the

–

load so that water can access all surfaces.

Do not place items inside other

–

pieces where they may be concealed.

Hollow instruments must be

–

throughly cleaned, internally and externally.

Ensure that instruments with long

–

narrow hollow sections can be flushed through properly before placing them in inserts or connecting them to jets.

Applications

Only process instruments made of

–

surgical steel, as these are less susceptible to corrosion.

Nickel plated instruments, colored

–

anodized aluminum instruments, or disposable instruments are not suitable for machine reprocessing.

Preparing the load

Empty all containers before loading

them into the machine.

Ensure that acids and residual

solvents, especially those containing hydrochloric acid or chlorides, do not get into the wash cabinet.

– Hollow vessels should be inverted

and placed in the correct baskets or inserts to ensure that water can flow into and out of them unrestricted.

– Large or concave items should be

placed at an angle to make sure water runs off them freely.

–

Tall, narrow, hollow items should be placed in the center of the baskets to ensure better water coverage.

–

Lightweight items should be secured with a cover net (e.g. an A 6) and small items placed in a mesh tray to prevent them from bouncing around or blocking the spray arms.

–

The spring adapter of the mobile units or baskets must be correctly engaged.

–

The spray arms must not be blocked by items which are too tall or which hang down in their path.

Loading instruments

Contaminated instruments can be placed directly in the machine without pre-treatment (no soaking required). Always refer to the surgical instrument manufacturer’s instructions for cleaning.

Chemically pre-treated instruments must be thoroughly rinsed before placing them in the machine.

Applications

Water connector spring adapter
