Abstract

A conveyor apparatus and a method for supplying a medicine-solution mixture from a plurality of medicine-active ingredient solutions and additional solution constituents in a body by means of a plurality of feed devices is disclosed. The medicine-active ingredient solutions have different medicine-active ingredient parameters and constituents; the solution constituents have different parameters and constituents. The constituents of at least two medicine-active ingredient solutions and solution constituents are saved in at least one storage device; and are selected by means of one selection device for selection of at least one specific parameter and/or constituent of each medicine-active ingredient solution and/or the solution constituents. By means of a calculating device, at least one additional parameter from all selected parameters is calculated for the control and operation of at least one additional feed device for supplying at least one additional medicine-solution mixture to the body.

Claims

1. A conveyor apparatus for supplying a medicament solution mixture of a plurality of medicament active agent solutions and/or solution constituents to a body, wherein the medicament active agent solutions and/or solution constituents have different medicament active agent parameters and/or ingredients, the conveyor apparatus comprising:

a plurality of feed devices;

at least one storage unit for storing the medicament active agent parameters and/or ingredients of at least two medicament active agent solutions and/or solution constituents being supplied by a corresponding at least two of the plurality of feed devices;

a selection unit connected to the at least one storage unit for selecting at least one of the stored medicament active agent parameters and/or ingredients from each of the at least two medicament active agent solutions and/or solution constituents;

a calculation unit for calculating at least one additional parameter based on the selected medicament active agent parameters and/or ingredients from each of the at least two medicament active agent solutions and/or solution constituents;

a controller for controlling the operation of at least one other of the plurality of feed devices for supplying at least one additional medicament solution mixture to the body based on the calculated additional parameter.

2. The conveyor apparatus as claimed in claim 1, wherein the at least one additional medicament solution mixture is a solution mixture for an artificial feeding and the medicament active agent solutions are nutrient solutions.

3. The conveyor apparatus as claimed in claim 2, wherein the medicament active agent parameters are the nutrient energy content of the nutrient solution.

4. The conveyor apparatus as claimed in claim 2, wherein the artificial feeding used is parenteral, enteral or a combination of the two.

5. The conveyor apparatus as claimed in claim 1, wherein the solution constituents are carrier solutions and preservative solutions.

6. The conveyor apparatus as claimed in claim 1, wherein the ingredients are carbohydrates, proteins and fats.

7. The conveyor apparatus as claimed in claim 1, wherein the calculation unit is connected to a blood sugar measuring device for measuring the blood sugar level in the body and to an input device for inputting body-specific data.

8. A method for supplying a medicament solution mixture of a plurality of medicament active agent solutions and solution constituents to a body by means of a plurality of feed units, wherein the medicament active agent solutions have various medicament active agent parameters and ingredients and the solution constituents have various parameters and ingredients, comprising the steps of:

storing the parameters and/or the ingredients of at least two medicament active agent solutions and solution constituents in at least one storage unit,

selecting, at least one specific parameter and/or ingredient from each medicament active agent solution and/or the solution constituents by means of a selection unit, and

calculating at least one additional parameter from all of the selected parameters for the control of the operation of at least one additional feed unit by means of a calculation unit, in order to supply at least one additional medicament solution mixture to the body.

9. The method as claimed in claim 8, wherein as a medicament solution mixture, a solution mixture for the artificial feeding is used, and as medicament active agent solutions, nutrient solutions having different nutrient energy contents are used as medicament active agent parameters.

10. The method as claimed in claim 9, wherein for the calculation of the additional parameter which is an insulin rate, body-specific data such as weight, age and insulin sensitivity of a patient, blood sugar level values of the patient as measured by means of an input device and by means of a blood sugar measuring device, as well as the nutrient energy contents and the time curve of the supply of the nutrient solutions by a plurality of infusion pumps are used.

11. The method as claimed in claim 9, wherein the artificial feeding used is parenteral, enteral or a combination of the two.

12. The method as claimed in claim 8 in that a warning indication is given in the case of an over- or underdosing of the supplied medicament solution mixture.
