Medical Assistant Prep / Unit 9 MAS 203 short lesson, about 20 seconds
Friction and Fluid
Captions available
The idea
Manual cleaning relies on two things: friction and fluid.
In practice
Friction means scrubbing soiled areas with a brush; fluid under pressure flushes soil from channels a brush cannot reach; ultrasonic cleaners loosen soil with sound waves in water.
Where people slip
Open hinged instruments fully, so cleaning reaches every surface.
