Cleaning Agents
A cleaning agent should be selected on basis of :
|
 |
|
| |
| ■ |
Compability with the device and the cleaning / washing method
selected (manual or mechanical); |
| ■ |
Type of soil present (protein soils are more easily removed with
alkaline detergents, mineral salts are more easily removed by
acidic detergents); |
| ■ |
Structure of device , a protein enzyme dissolving solution
should be used when cleaning medical devices that have lumens
or joints(eg.scopes) |
| |
|
|
|
| |
Pre-soaking / Pre-rinsing Methods
To remove the visible and invisible debris, after desassembling the
devices should be either:
|
|
| |
| ■ |
Soaked in cool (20 - 43°C) water and / or an enzyme product
that dissolves blood and other proteinaceous materials , or; |
| ■ |
Pre-rinsed with an abundant amount of running tap water in a
range of 20-43°C. |
| |

Cleaning Methods
The choice of methods and procedures used for cleaning depends
on the medical device being cleaned. Cleaning may be
accomplished manually or mechanically or by a combination of
these methods.
Manual Cleaning
Manual cleaning is required for certain dedicate or complex
medical devices.
To facilitate manual cleaning,medical devices
should be :
|
|
|
| |
| ■ |
Cleaned under water to prevent aerosolizing (if submersible); |
| ■ |
Cleaned with non-abstractive implements , to prevent damage
to instruments (devices with lumens or small holes should be
cleaned with brushes of appropriate diameter.Brushes should be
disinfected daily);
|
| ■ |
Rinsed with an abundant amount of running tap water in a
range of 50-65°C to remove detergents (de-ionized and distilled
water is preferred).
