Implemented directly at the “point of care”, the cobas b 123 POC system analyses various blood parameters, from blood gases to blood glucose. The design concept is marked by functionality and user-friendliness. Fluids and tubes that accumulate during use are kept in a sealed, exchangeable container within the maintenance-free blood gas analysis system. This protects users against infections at all times. An easy-access lid on the front of the device allows for the safe exchange of the waste container.
