Sterility procedure recommended for NON-STRILE medical devices

Sterilize the 3-Way syringe Nozzle provided by Osstem in its container with water vapor in an

autoclave in accordance with standard hospital procedure. The sterilization method suggested has

been validated according to the AAMI ST 79 in order to obtain a Sterility Assurance Level (SAL) of

10-6.

Sterilization method: steam, Cycle: Saturated steam with forced air removal AUTOCLAVE:

porous load or gravity, Temperature: 132℃, Exposure time: 7 minutes, Dry time : 15min and

Pressure for gravity autoclave: 2,5Bars/ 36-PSIG.

Other sterilization methods are possible but must be validated beforehand.

The autoclave must be validated by the hospital and regularly checked to guarantee the

recommended sterilization temperature is reached for the entire exposure time.

If sterilization containers with paper filter are used, it is advisable to use new filter for each

sterilization.

If after having following this sterilization method there is still water in the sterilization contains or

on/inside the device, the device must be dried and sterilization repeated.

■ “Blue cut” feature

• The Lamp has a “blue cut” or “non-curing” feature. This feature is intended to reduce the intensity of

blue light wavelengths and therefore reduce premature curing of light-cured resins and

composites during dental procedures.

• The blue-cut feature is implemented using a yellow absorption filter which is manually moved into

position by the user as shown in [Fig. 55]

13. Cleaning and Maintenance

13-1. Barrier Protection

• Osstem recommends barrier protection for all applicable touch and transfer surfaces.

Touch surfaces are areas that come into contact with hands and become potential cross-contamination

points during dental procedures. Transfer surfaces are areas that come

into contact with instruments and other inanimate objects.

Barriers must be produced as the medical device regulations specific to your location.

Caution

If you use barriers, always replace the barrier film after each patient.

13-2. Upholstery

To preserve the quality of your Osstem upholstery, use barrier covers

instead of relying on chemicals. Barriers significantly extend the life of the upholstery and will

help to preserve its luxurious look and soft feel. To clean the upholstery, use a solution of mild detergent

and water. Use surface disinfectants only when the barriers have been compromised or if there is visible

spatter on the upholstery.

Caution

Minimize the use of surface disinfectants on the upholstery.

Chemicals can cause deterioration and shorten the life of upholstered surfaces.

Caution

• Disposal

- Any waste which is generated must be recycled or disposed of in strict compliance with all

applicable national regulations in a manner which is safe both for people and the environment.

• Disposal of electronic and electrical devices

- According to EC directive 2002/96 concerning used electrical and electronic devices, this product

is subject to the cited directive and must be disposed of accordingly within Europe.

UNIT CHAIR [OS-UM-C002 Ver.2]

Page 74

13-3. Cleaning the Unit

• Use a solution of mild, non-ionic detergent and water, or commercially available cleaners

containing no alcohol, bleach, or ammonia. Dishwashing detergent is usually non-ionic.

Because the hardness of water varies from locale to locale, you should experiment to

determine the best mix of detergent to water. Mix just enough detergent to allow for good

cleaning without leaving a soapy film on the surface. Never use abrasive cleansers,

scrubbing pads, or other abrasive applicators because they can permanently scratch or otherwise

damage equipment surfaces. Be careful using recycled paper products, such as paper

towels, that may be abrasive.

• The Spittoon and Spittoon Filter should be detached and cleansed once a day. As for the

cleaning method, separate the Cup Holder from the water cleaning pipe, detach the Spittoon, lift the

Spittoon Filter Stopper, first, and then take out the Spittoon Filter, and remove solid

waste and cleanse the Spittoon.

• After many uses, suctioning capacity may be compromised when suction filter is blocked

with solid waste. Thus, waste must be removed once every two days by taking out the filter

stopper. To clean take out the stopper from filter and remove waste from the net.

■ Method of Cleaning

To disconnect the nozzle from the 3-Way Syringe,

press down on the nozzle connection point and

pull the nozzle out.

Disinfect the disconnected nozzle in an

Autoclave at 132°C for more than 7 minutes.

Additionally, to clean the 3-Way Syringe, use a

solution of mild detergent and water. Use surface

disinfectants only when the barriers have been

compromised or if there is visible spatter on the

3-Way Syringe

Reference

The 3-Way syringe Nozzle provided by Osstem is not sterilized.

Before using for the first time, sterilize according to the information below.
