Probes and Biopsy 13-9
13.1.5 Probe Cleaning, Disinfection and Sterilization
Before and after each examination, clean and disinfect (or sterilize) the probes as required.
When biopsy procedures have been performed, be sure to sterilize the needle-guided bracket.
Fail to do so may result in the probe and the needle-guided bracket to becoming sources of
infection. Please follow the instructions in the manual for cleaning.
WARNING:
Never immerse the probe connector into liquid such as water or
disinfectant. Immersion may cause electrical shock or
malfunction.
CAUTION:
When performing cleaning and
disinfection of the probe to prevent
infection, wear sterile gloves.
After disinfection, rinse the probe thoroughly with sterile
water to remove all chemical residues. Chemical residues on
the probe may be harmful to the human body.
No cleaning and disinfecting may result in the probe
becoming a source of infection.
Please follow the disinfectant manufacturer's manual for
performing cleaning and disinfection, including preparing
sterile water and cleaning and disinfection time.
1.
After the examination, wipe off the ultrasound gel thoroughly. Otherwise, the
ultrasound gel may solidify and degrade the image quality of the transducer.
DO NOT make the probe to become overheated (more than 55°C) during
cleaning and disinfections. High temperature may cause the probe to become
deformed or damaged.
Cleaning and Disinfection/sterilization Overview
Cleaning and disinfection refer to two distinct processes. According to the Centers for
Disease Control and Prevention (CDC) "Guideline for Disinfection and Sterilization in
Healthcare Facilities" (2008):
"Cleaning is the removal of visible soil (e.g. organic and inorganic material) from objects and
surfaces and normally is accomplished manually or mechanically using water with detergents
or enzymatic products. Thorough cleaning is essential before high-level disinfection and
sterilization because inorganic and organic material that remains on the surfaces of
instruments interfere with the effectiveness of these processes."
"Disinfection describes a process that eliminates many or all pathogenic microorganisms,
except bacterial spores."
Low-Level Disinfection—Destruction of most bacteria, some viruses, and some
fungi. Low-level disinfection will not necessarily inactivate Mycobacterium
tuberculosis or bacterial spores.
High-Level Disinfection (HLD)—Destruction/removal of all microorganisms except
bacterial spores.
