Control system

A control system is provided for controlling blood gas values in blood processed by an oxygenator. The oxygenator generates arterial blood by exposing venous blood to oxygen from an oxygenation gas supply. A monitoring arrangement determines the blood gas values in the arterial blood and a controller responsive to the monitoring arrangement controls parameters of the oxygenation gas supplied to the oxygenator. This allows the blood gas values to be adjusted toward a pre-determined level. The oxygen supply may be altered via the flow rate or gas composition. The monitoring arrangement may continuously monitor the blood using non-contact methods. It may monitor the oxygen and carbon dioxide in the inlet gases, exhaust gases, and venous and arterial blood, in order to calculate the oxygen uptake and hence an expected blood gas level; it may also calculate a difference between the expected and actual blood gas levels and thus apply an offset to the change in gas supply to take into account ...

Maintenance notification for medical devices

A medical device includes a plurality of electromechanical components and a control unit, coupled to the electromechanical components, that actuates the electromechanical components. For each of the electromechanical components, the control unit maintains a count of a number of times a respective one of the electromechanical components is actuated and/or a run time duration of the respective one of the electromechanical components. The medical device also includes a table having observed values for each of the electromechanical components, where a maintenance alert is provided for at least one of the electromechanical components in response to the count and/or the run time for the at least one of the electromechanical components exceeding a corresponding maintenance limit for the electromechanical component. The maintenance limits are independent for different ones of the electromechanical components. The medical device may be a dialysis machine.
