Abstract

A system for managing personal health device measurement data based on the HL7 CDA (Clinical Document Architecture) standard includes: a reception unit receiving a device CDA from a health gateway; a CDA analyzing unit analyzing the device CDA delivered from the reception unit to extract header information and health measurement information; a user/device database (DB) storing the header information which has been extracted by the CDA analyzing unit; and a personal health record (PHR) DB storing the health measurement information which has been extracted by the CDA analyzing unit.

Claims

1. A system for managing personal health device measurement data based on HL7 CDA standard, the system comprising:

a reception unit receiving a device CDA(Clinical Document Architecture) from a health gateway;

a CDA analyzing unit analyzing the device CDA delivered from the reception unit to extract header information and health measurement information;

a user/device database (DB) storing the header information which has been extracted by the CDA analyzing unit; and

a personal health record (PHR) DB storing the health measurement information which has been extracted by the CDA analyzing unit.

2. The system of claim 1, further comprising:

a health history check request processing unit searching the user/device DB and the PHR DB according to a health history request received from the exterior;

a CDA merging unit configuring a health history CDA document by using search results delivered from the health history check request processing unit; and

a transmission unit providing the health history CDA, which has been configured by the CDA merging unit, to the exterior.

3. The system of claim 1, wherein the device CDA is personal health data which has been measured according to an ISO/IEEE 11073 PHD (Personal Health Device) international standard by a personal health device and then converted into an HL7 CDA format, which includes data measured once by one personal health device.

4. The system of claim 1, wherein the CDA analyzing unit extracts header information from computer processing blocks of a header and an entry of the device CDA and then extracts the health measurement information.

5. The system of claim 1, wherein the header information comprises user information and device information.

6. The system of claim 1, wherein the health measurement information is divided into numeric data expressed as a numeric value, enumeration data expressing an event, and an RT-SA (RealTime-SampleArray) data expressing waveform data according to measurement data by a personal health device.

7. The system of claim 1, wherein the user/device DB stores the header information in the format of a user information table, a device information table, and a device attribute information table.

8. The system of claim 7, wherein the user information table comprises any one or more of a USER ID column storing a user ID, a GENDER column storing the gender of a user, a GIVENNAME column storing a user'"'"'s name, a FAMILYNAME column storing a user'"'"'s family name, an ADDRESS column storing a user'"'"'s address, a HOME_PHONE column storing a user'"'"'s phone number, a MOBILE_PHONE column storing a user'"'"'s mobile phone number, and a BIRTH_TIME column storing a user'"'"'s birth date.

9. The system of claim 1, wherein the device information table comprises any one or more of a DEVICE_ID column storing an ID of a personal health device, a MODEL_NAME column storing a model name of a maker of the personal health device, a SCOPING_ENTITY column storing a scoping entity tag, a DATE SUPPLY column storing an effective time tag, and a CODE column storing a code attribute of a code tag of the personal health device.

10. The system of claim 7, wherein the device attribute information table comprises any one or more of a DEV_ATTR_KEY column storing a key value of measurement data stored in the PHR DB, a CODE column storing a code attribute of a code tag of observation, a VALUE column storing measurement data, and a UNIT column storing the unit of the measurement data.

11. The system of claim 1, wherein the PHR DB stores the health measurement information in the format of a PHR information table.

12. The system of claim 1, wherein the PHR information table comprises any one or more of a USER_ID column storing a user ID of a device CDA, a DEVICE_ID column storing an ID of a personal health device, a CODE column storing the type of measurement data, an EFFECTIVE_TIME column storing a measurement time, a VALUE column storing measurement data, a UNIT column storing the unit of the measurement data, and a DEV_ATTR_KEY column storing a specific ID for a device attributer information table.

13. The system of claim 12, wherein, in the PHR information table, data of every column excluding the DEV_ATTR_KEY column is input as the numeric data among the health measurement information, data of the columns excluding the VALUE column, the UNIT column, and the DEV_ATTR_KEY column is input as the enumeration data, and data of every column excluding the UNIT column is input as the RT-SA data.

14. The system of claim 13, wherein, in the PHR information table, the accuracy and sampling frequency of the personal health device is expressed through the device attribute information table by using the DEV_ATTR_KEY column.

15. The system of claim 2, wherein the health history check request processing unit generates an SQL (Structured Query Language) statement on the basis of health history check request data received from an external source and search the user device DB and the PHR DB.

16. The system of claim 15, wherein the health history check request data comprises any one or more of a user ID, a device ID, a start time, an end time, and a measurement data type item.

17. The system of claim 2, wherein the CDA merging unit configures a recordTarget tag by using user information retrieved from the user/device DB, reconfigure a medical equipment block by using device information retrieved from the user/device DB, and dynamically generate a narrative block of the medical equipment block on the basis of the reconfigured content.

18. The system of claim 17, wherein when the health measurement information retrieved from the PHR DB has a value and unit value, the CDA merging unit reconfigures a numeric block, when the health measurement information retrieved from the PHR DB does not have the value and unit value, the CDA merging unit reconfigures an enumeration block, and when the value is an arrangement of values, the CDA merging unit reconfigures an RT-SA block.

19. The system of claim 18, wherein the health history CDA configured by the CDA merging unit comprises data measured several times by a plurality of personal health devices.

20. The system of claim 19, wherein the CDA merging unit collects data which has been measured at the same time by personal health devices to configure the same as a bundle of a plurality of components in a single entry, arranges a plurality of entries configured by collecting data measured at the same time with respect to respective personal health devices in order of measurement time to configure an entry column, arranges entry columns configured by personal health device in random order, and dynamically generates a narrative block with respect to a vital sign section on the basis of content of the entry column, thus configuring the health history CDA.
