Probe handling and infection control
This information is intended to increase user awareness of the 
risks of disease transmission associated with using this 
equipment and provide guidance in making decisions directly 
affecting the safety of the patient as well as the equipment user.
Diagnostic ultrasound systems utilize ultrasound energy that 
must be coupled to the patient by direct physical contact.  
Depending on the type of examination, this contact occurs with a 
variety of tissues ranging from intact skin in a routine exam to 
recirculating blood in a surgical procedure.  The level of risk of 
infection varies greatly with the type of contact.
One of the most effective ways to prevent transmission between 
patients is with single use or disposable devices.  However, 
ultrasound transducers are complex and expensive devices that 
must be reused between patients.  It is very important, therefore, 
to minimize the risk of disease transmission by using barriers 
and through proper processing between patients. 
Risk of Infection. ALWAYS clean and disinfect the probe 
between patients to the level appropriate for the type of 
examination and use FDA-cleared probe sheaths where 
appropriate.  
Adequate cleaning and disinfection are necessary to prevent 
disease transmission.  It is the responsibility of the equipment 
user to verify and maintain the effectiveness of the infection 
control procedures in use.  Always use sterile, legally marketed 
probe sheaths for intra-cavitary and intra-operative procedures.
For neurological intra-operative procedures, use of a legally 
marketed, sterile, pyrogen free probe sheath is REQUIRED.  
Probes for neuro surgical use must not be sterilized with liquid 
chemical sterilants because of the possibility of neuro toxic 
residues remaining on the probe.
