Abstract

A system and a method for monitoring at least one blood parameter of blood of different patients, comprising a plurality of access devices for establishing at least one access to the blood of each patient through skin, a plurality of removal devices for removing a quantity of the blood from each patient in order to obtain at least one blood sample, at least one blood analysis device for analyzing the at least one blood sample with respect to predeterminable blood parameters and for generating individual blood parameter data sets, a calculation device which can be used jointly for a plurality of blood parameter data sets of the different patients for calculating data sets of drug parameters of drugs to be administered to a respective patient on the basis of the individual blood parameter data sets, and a plurality of supply devices for supplying a respective drug having the calculated data sets of the drug parameters.

Claims

1. A system for monitoring at least one blood parameter of blood of different patients, the system comprising:

a multiplicity of access devices each to create at least one access to the blood of each patient through his or her skin;

a multiplicity of extraction devices each to extract a blood quantity from each patient to obtain in each case at least one blood specimen;

at least one blood analysis device to analyse the at least one blood specimen in relation to predefinable parameters of the blood and to generate individual blood parameter datasets;

a calculation device which can be used in common for a multiplicity of blood parameter data sets of the different patients to calculate data sets of medicament parameters of medicaments to be administered to a respective patient on the basis of the individual blood parameter data sets;

a multiplicity of supply devices to supply the respective medicaments to the respective different patients in accordance with the calculated data sets of the medicament parameters for each of the different patients, and

an association device configured to;

allocate in each case an identification code to identify a patient and a period of time code to specify a period of time in which the at least one blood specimen was taken, to each data set of the medicament parameters calculated by the calculation device, such that a common data set is created for each respective patient; and

transmit each common data set including a respective data set of the calculated data sets of the medicament parameters for each of the different patients together with the identification code and the period of time code, from the calculation device by a hard-wired link or a wireless link to a respective supply device, wherein each respective supply device is selected based on the identification code and the period of time code; and

each respective supply device supplies a corresponding amount of a respective medicament according to the common data set for each respective patient.

2. The system according to claim 1, wherein the association device is arranged in the calculation device.

3. The system according to claim 1, further comprising at least one identification element generating device, by means of which, immediately after taking of the blood quantity and before supply to the at least one blood analysis device, each at least one blood specimen can be associated with the identification code and the period of time code in the form of a barcode, a data matrix code and/or a transponder on an extraction device containing the at least one blood specimen.

4. The system according to claim 3 wherein the at least one blood analysis device comprises a read unit to read the barcode, the data matrix code and/or the transponder.

5. The system according to claim 4, wherein the at least one blood analysis device is connected with the calculation device which is connected with the supply devices for data transfers.

6. The system according to claim 3, wherein the extraction device is a syringe or a blood extraction tube, wherein a blood receiving container of the extraction device, or a blood receiving container connected to the extraction device, is connected with the barcode, the data matrix code and/or the transponder.

7. The system according to claim 1, wherein the data sets of the medicament parameters are encrypted.

8. The system according to claim 1, wherein within the common dataset, a data set of the medicament parameters with data of the identification code and the period of time code is frequency- and or amplitude-modulated.

9. The system according to claim 1, wherein the common data set is present in binary code.

10. A method for monitoring in each case at least one blood parameter of the blood of different patients, said method comprising the steps of:

creating in each case, with a multiplicity of access devices, at least one access to the blood of each patient through his or her skin;

extracting, with a multiplicity of extraction devices, a blood quantity from each patient to obtain in each case at least one blood specimen;

analyzing, with at least one blood, analysis device, the blood specimen in relation to predefinable parameters of the blood;

generating, with the at least one blood analysis device, individual blood parameter data sets;

calculating, with a calculation device which can be used in common for a multiplicity of blood parameter data sets of the different patients, data sets of medicament parameters of medicaments to be administered to a respective patient on the basis of the individual blood parameter data sets;

supplying, with a multiplicity of supply devices, the respective medicaments to the respective different patients in accordance with the calculated data sets of the medicament parameters for each of the different patients; and

allocating in each case, with an association device, an identification code to identify a patient and a period of time code to specify a period of time in which the at least one blood specimen was taken, to each data set of the medicament parameters calculated by the calculation device, such that a common data set is created for each respective patient; and

transmitting, with the association device, each common data set including a respective data set of the calculated data sets of the medicament parameters for each of the different patients from the calculation device, together with the identification code and the period of time code, by a hard-wired link or a wireless link to a respective supply device, wherein each respective supply device is selected based on the identification code and the period of time code; and

supplying, with each respective supply device, a corresponding amount of a respective medicament according to the common data set for each respective patient.
