- Devices, devices and methods for the computer-controlled infusion of drugs with the regulation in humans can be made to scientific and clinical issues are well known, the known devices and methods are adapted to the equipment and performance profile of each task.
- devices and methods for the regulation of, for example, glucose are known, whose devices consist essentially of the components infusion pump for insulin, infusion pump for glucose, a measuring device for determining the blood glucose level and a computer unit for implementing the method for glucose regulation.
- Such devices are available for use as a controlled insulin pump for the administration of insulin or as combined infusion devices for the administration of insulin and glucose.
- the blood glucose is measured either non-invasively spectroscopically, minimally invasive via the glucose determination of the interstitial fluid or via an implanted sensor minimally invasive or directly bloody.
- these known devices have the disadvantage that problems and inaccurate results can occur if the integrated measuring devices fail to determine the blood glucose level or the measurement accuracy is impaired by drift or other factors, since the accuracy of the measured values determined directly affects the quality the regulation of blood glucose levels.

- This solution describes the manual venous blood glucose value generation integrated in an open-loop system with computer-controlled, automated control for insulin and glucose infusion for quasi-continuous blood glucose control.
- the device is only suitable for regulating insulin and glucose infusion, a further determination of intensive medical parameters, such as sodium and potassium and their regulation in the context of intensive care and intensive care are not possible with this solution presented.
- the device should be designed in such a way that an additional, short-term available determination of further parameters for the intensive monitoring is available within the scope of an intensive monitoring or therapy.
- the state of development of blood sugar and blood mineral measurement technology allows the use of high-precision measuring instruments, which are validated by laboratory use and interlaboratory tests and provide higher measurement accuracy and greater stability of the expected measurement results.
- a discrete-time determination of blood sodium and blood potassium is carried out in combination with high-precision measuring instruments which calibrate themselves for the determination of glucose and irisulm. This is done at certain measurement intervals, which are adapted to the experimental conditions such that there are short measurement intervals in a first time range and subsequently, after modeling could be validated, the measurement intervals by the accumulation of data and modeling of the current sodium potassium -Regulation system can be extended.
- a recovery of the necessary parameters is time-discrete in short quasi-equivalent time intervals, but they may be different according to the respective test requirements and conditions. Also, not all of the mentioned measured values need to be determined at the same time intervals.
- the intervals for obtaining the measured value of the individual parameters are specified by the experimenter or physician and can be adapted to the current requirements during the examination.
- the data are accumulated, rules for the description of the individual control systems for sodium and potassium are derived and the necessary parameters are estimated, as they are used for the regulation of the parameters. a certain level over a longer period are necessary.
- the necessary parameters are obtained at longer intervals and their regulation then takes place according to the model for regulation created in the first time range.

- the computer unit a standard computer unit, consists of an industrial PC, a laptop, pocket PC, industrial workstation or panel computer. Whenever a new measured value has been determined with the external sensor continuously connected to the patient, the automatic transmission to the computer unit and to the process sequence software takes place.
- the procedural software evaluates the received measured value in conjunction with the history of the already stored measured values, and for the period between the real measured value readings, measured values are determined which are fed to the control algorithm for calculating the necessary infusion quantities.
- the program system allows the integration of new software modules to apply new scientific methods for sodium and potassium regulation.
- the program on which the computer unit operates is variably configurable so that the attached device and measurements taken by it are used to determine and regulate the values for the sodium and potassium potassium.
- the device created is for use in the intensive care application for the regulation of sodium and potassium levels at a presettable level for the treatment of disorders of the mineral balance after intensive care operations and therapy in emergency situations (eg cardiac arrhythmia, severe exciscose, the water and mineral balance relevant hormone / regulatory disorders), further for computer-aided, automated glucose regulation with a similar field of application for the regulation to a presettable level for the therapy of disorders of the glucose balance after intensive care interventions and therapy in emergency situations (eg diabetic coma).
- emergency situations eg cardiac arrhythmia, severe exciscose, the water and mineral balance relevant hormone / regulatory disorders
