Abstract

The present invention relates to the field of non-invasive blood pressure (NIBP) monitoring systems and particularly to a system that allows the identification of other components of the system via coding elements that are readable without the need for placement of this system components to the body of a patient.

Claims

1. A method for the identification of a plurality of system components of a non-invasive blood pressure system, the method comprising:

wirelessly identifying a plurality of system components that include unique coding elements that encode information with a reading unit of a monitor including reading-out the information encoded by the coding element of the system components without attaching the identified system components to a body of a patient;

wherein the plurality of identified system components includes a hose and at least one of a cuff and a rack; and

checking, with the monitor, a compatibility of the identified hose component with each other identified system component based on the information encoded by the respective coding elements.

2. The method according to claim 1, wherein the wireless identification of the system components is read by the reading unit via at least one of electromagnetic radiation, high frequency transmission and infrared transmission.

3. The method according to claim 1, further including:

reading a patient identifier from the coding elements of the system components;

automatically correlating an outcome of a blood pressure measurement with patient data by linking of the information encoded by the coding element with outcome of a blood pressure measurement and a patient record.

4. The method according to claim 1, further including:

reading a patient identification from the coding elements of the system components;

determining if the system components are a correct assembly for the patient identification;

automatically starting a blood pressure measurement in response to the system components being in a correct assembly for the patient identification; and

suggesting a correct assembly for the patient identification in response to the system components being in an incorrect assembly for the patient identification.

5. A non-invasive blood pressure measuring system, the system comprising:

a monitor;

a plurality of further system components including a hose and at least one of a cuff and a rack, each of the plurality of further system components including a coding element encoding information; and

a reading unit configured to wirelessly identify at least two of the further system components by reading the information encoded by the coding element of each of the further system components;

wherein the monitor is configured to check a compatibility of the identified hose component with each other identified further system component based on the information encoded by the respective coding elements.

6. The non-invasive blood pressure system according to claim 5, wherein each coding element is configured to be read by the reading unit without attaching the further system components to a body of a patient.

7. The non-invasive blood pressure system according to claim 5, wherein each coding element encodes information that is readable using the monitor via at least one of electromagnetic radiation, high frequency transmission, or infrared transmission.

8. The non-invasive blood pressure system according to claim 5, wherein at least one coding element includes a patient identification.

9. The non-invasive blood pressure system according to claim 8, wherein the monitor is configured to automatically correlate an outcome of a blood pressure measurement with the patient identification by linking the information encoded by the coding element with measurement data and storing the measurement data in a patient record of the identified patient.

10. The non-invasive blood pressure system according to claim 8, wherein the monitor is configured to automatically adjust operational characteristics of the system based on the identified further system components and the patient identification.

11. The non-invasive blood pressure system according to claim 8, wherein the monitor is configured to compare the identified further system components with assembly information corresponding to the patient identification to ensure a correct assembly of the further system components for the identified patient.

12. The non-invasive blood pressure system according to claim 11, wherein in response to an incorrect assembly of the system being used for the patient identification, the monitor is configured to suggest a correct assembly.

13. A non-invasive blood pressure monitoring system comprising:

a pressure cuff configured to be fitted over a limb of a patient;

a cuff coding element attached to the pressure cuff and configured to store encoded information including at least an identification of characteristics of the pressure cuff;

a hose configured to be attached to the pressure cuff;

a hose coding element attached to the hose and configured to store encoding information including at least an identification of characteristics of the hose; and

,

a monitor configured to be attached to the hose and being configured to;

read the cuff coding element and the hose coding element, and

determine the compatibility of the pressure cuff and hose.

14. The non-invasive blood pressure monitoring system according to claim 13, wherein at least one of the coding elements is configured to store patient specific data and the monitor is further configured to:

access patient electronic files based on the stored patient specific data,

determine if the pressure cuff and hose are compatible with the patient.

15. The non-invasive blood pressure measuring system according to claim 14, wherein the monitor is configured to automatically correlate an outcome of a blood pressure measurement with the patient by linking with the patient electronic files.

16. The non-invasive blood pressure system according to claim 14, wherein, in response to the pressure cuff and hose being determined to be compatible with the identified patient, the monitor is further configured to automatically compute and adjust a blood pressure measurement based on the identified pressure cuff and hose with linked information encoded by the coding elements.

17. The non-invasive blood pressure monitoring system according to claim 13, further including:

a rack configured to be connected with the pressure cuff;

a rack coding element attached to the rack and configured to store encoded information including at least one of an identification of characteristics of the cuff or a patient identifier.

18. The non-invasive blood pressure measuring system according to claim 13, wherein each of the coding elements encodes information that is readable at the monitor by receipt of at least one of electromagnetic radiation, high frequency transmission, and infrared transmission.

19. The non-invasive blood pressure measuring system according to claim 13, wherein each of the coding elements is a radiofrequency identity (RFID) tag or a bar code.
