Abstract

The invention relates to a system and method for monitoring at least one blood parameter of the blood of various patients by means of a plurality of access devices for in each case setting up at least one access to the blood of each patient through his skin, a plurality of extraction devices for extraction of an amount of blood from each patient in order to obtain at least one blood sample in each case, blood analysis devices, which are used jointly for a plurality of blood samples, for analysis of predeterminable parameters of the blood from the blood sample, a common calculation device for calculation of medicament parameters for the medicaments to be prescribed to the respective patient on the basis of data records of the determined parameters of the analyzed blood, and a plurality of feed devices for feeding in the respective medicament with the calculated medicament parameters.

Claims

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

a plurality of access devices for establishing respectively at least one access to the blood of each patient through his or her skin;

a plurality of sampling devices for respectively taking an amount of blood from each patient, in order to obtain respectively at least one blood sample;

a blood analysis device that can be commonly used for a plurality of blood samples from different patients, for analysing the blood sample with respect to specifiable parameters of the blood;

a common calculation device for calculating medicament parameters of the medicaments to be administered to the respective patients, on the basis of data records of the determined parameters of the analysed blood; and

a plurality of feeding devices for feeding the respective medicament with the calculated medicament parameters, and

an association device for associating respectively one identification label for identifying a patient and/or a time period label for indicating a time period during which the blood was taken, to each data record of the parameters of the analysed blood of a patient, which were determined by the blood analysis device.

2. The system as claimed in claim 1, wherein the association device is provided within the blood analysis device.

3. The system as claimed in claim 1, wherein each data record of the determined parameters of the analysed blood can be transferred in a wired or wireless manner respectively as a common data record from the blood analysis device to one or more feeding devices together with the patient-specific identification label and the time period label.

4. The system as claimed in claim 1, further comprising at least one identification element generation device, by means of which the identification label and/or the time unit label can be associated with each blood sample on the sampling device containing the blood sample immediately after the amount of blood has been taken and prior to it having been fed to the blood analysis device, in the form of a barcode, a data matrix code and/or a transponder.

5. The system as claimed in claim 1, wherein the blood analysis device includes a reading unit for reading the barcode, the data matrix code and/or the transponder.

6. The system as claimed in claim 5, wherein the blood analysis device is connected to the calculation device and the calculation device is connected with all of the feeding devices for a data transfer.

7. The system as claimed in claim 1, wherein the identification label and the time period label and/or the determined parameter data are encrypted.

8. The system as claimed in claim 1, wherein the sampling device is a syringe or a blood sampling tube, the blood collection container of which or a blood collection container coupled therewith is linked on the outside thereof with the barcode, the data matrix code and/or a transponder.

9. The system as claimed in claim 3, wherein within the common data record, the data record of the determined parameters is frequency and/or amplitude modulated with the data of the identification label and the time period label.

10. The system as claimed in claim 3, wherein the common data record is present in a binary-coded form.

11. A method for monitoring respectively at least one blood parameter for blood of various patients, comprising the following steps:

establishing respectively at least one access to the blood of each patient by means of a plurality of access devices;

taking an amount of blood from each patient, in order to obtain respectively at least one blood sample, by means of a plurality of sampling devices;

analysing the blood sample with regard to the specifiable parameters of the blood by means of blood analysis devices that can be commonly used for a plurality of blood samples from different patients;

calculating medicament parameters of the medicaments to be administered to the respective patients on the basis of data records of the determined parameters of the analysed blood by means of a common calculation device; and

feeding the respective medicament with the calculated medicament parameters by means of a plurality of feeding devices;

wherein by means of an association device, respectively one identification label for identifying a patient and/or a time period label for indicating a time period during which the blood was taken, are associated with each data record of the parameters of the analysed blood, which were determined by the blood analysis device, of a patient.

12. The method as claimed in claim 11, wherein each data record of the determined parameters of the analysed blood is transferred in a wired or wireless manner respectively as a common data record from the blood analysis device to one or more of the feeding devices together with the identification label and the time period label.
