is damaged in this manner and then used to continue therapy, vascular 

injury or tissue burns could occur. 

 

WARNING

! 

Avoid spilling fluids on the cables and Control Unit.  Do not immerse any 

portion of the cables or Control Unit in water or other fluids.  Fluids may 

cause the equipment to perform inaccurately or fail, which could result in 

vascular injury.  Additionally, fluids could result in fire or electric shock. 

 

WARNING

! 

The Control Unit is intended for use with the EkoSonic™ Device, 

approved cables and electronic devices.  Do not connect non-EKOS 

devices, cables (e.g., power cord) or electronic equipment to the Control 

Unit.  Use of non-approved devices, cables and electronic equipment 

could result in electric shock or burn, increased electromagnetic 

interference (EMI) emissions, decreased immunity to EMI from other 

sources, or delay of therapy. 

 

WARNING

! 

The reusable Connector Interface Cable and Control Unit are NOT 

STERILE.  Use caution if maintaining a sterile operating field after 

connecting to the EkoSonic™ Device.  Failure to do so could result in 

patient infection. 

 

WARNING

! 

Inspect all connectors, cables and the Control Unit for damage prior to 

use.  If damaged (e.g., exposed wires), do not use and replace 

immediately. 

 

 

WARNING

! 

Ensure all connectors are dry before connecting the Connector Interface 

Cable to the Control Unit or the Connector Interface Cable to the 

EkoSonic™ Device.  If connectors do become wet, thoroughly dry prior 

to use.  Fluid in the connectors may affect sensor accuracy and result in 

vascular injury. 

 

WARNING

! 

Connect system cables only to their proper connectors as marked and 

ensure connections are secure.  Failure to do so could result in electric 

shock or burn. 

 

WARNING

! 

Secure device cables and the Connector Interface Cable using standard 

practices to preserve the integrity of the device, minimize device 

movement at the insertion site, and prevent device dislodgement.  If the 

Connector Interface Cable is dropped, it has sufficient weight to pull on 

the device and possibly dislodge it from where it has been inserted into 

the patient. 

 

WARNING

! 

The Control Unit should be placed on a flat table or attached to the 

EKOS™ CU 4.0 Cart or an

 

infusion stand during use.  If attached to an
