Abstract

A medical device system (10) including a distributed database (10a to 10f); a plurality of medical devices (12) operating with the distributed database (10a to 10f); and a logic implementer (20) associated with each medical device (12), wherein each logic implementer (20) is programmed to access the distributed database (10a to 10f), so that each medical device (12) of system (10) periodically (i) delivers at least one of prescription input parameters or treatment output data to and (ii) retrieves at least one of prescription input parameters or treatment output data from each of the other medical devices (12).

First claim

The invention is claimed as follows:

1. A medical device system comprising:
a plurality of medical devices each including a memory, the plurality of medical devices communicatively coupled such that the memories collectively form a distributed database;
and
a logic implementer associated with each medical device, wherein each logic implementer is programmed to automatically access the distributed database, so that each medical device of the system periodically (i) delivers at least one selected from the group consisting of prescription input parameters and treatment output data to at least one of the other medical devices and (ii) retrieves at least one selected from the group consisting of prescription input parameters and treatment output data from at least one of the other medical devices,
wherein the medical devices are configured to communicate directly with at least one of the other medical devices via the distributed database,
wherein at least one of the logic implementers is configured to periodically push at least one of the prescription input parameters or the treatment output data to at least one of the other medical devices without instruction from a centralized server,
wherein at least one of the logic implementers is configured to periodically pull at least one of the prescription input parameters or the treatment output data from at least one of the other medical devices without instruction from a centralized server by
after receiving a request to perform a renal failure treatment for a patient in a logic implementer of a selected one of the medical devices, compare, via the logic implementer a most recent time stamp of prescription input parameters related to the patient at the selected medical device to time stamps of prescription input parameters related to the same patient at the other medical devices,
determine a most recent time stamp in one of the other medical devices,
select the prescription input parameters corresponding to the most recent time stamp from the other medical device, and
locally store in the selected medical device the prescription input parameters corresponding to the most recent time stamp to perform the renal failure treatment for the patient, and

wherein the medical devices are renal failure therapy machines.

2. The medical device system of claim 1 , wherein the medical devices are in data communication with each other via a local area network used in connection with the distributed database.

3. The medical device system according to claim 1 , wherein each of the medical devices is updated to store the same at least one of the prescription input parameters or the treatment output data for each of a plurality of patients.

4. The medical device system according to claim 1 , wherein the medical devices and the distributed database do not interact with a centralized server.

5. The medical device system according to claim 1 , wherein the medical devices are provided by first and second manufacturers, and which includes an interface enabling the medical devices of the first and second manufacturers to communicate with one another.

6. The medical device system according to claim 1 , wherein at least one selected from the group consisting of the (i) prescription input parameters and (ii) treatment output data is shared via the distributed database along with at least one other selected from the group consisting of (iii) technical input data, (iv) technical output data, and (v) administrative data.

7. The medical device system according to claim 1 , wherein the distributed database also shares information from at least one medical equipment selected from the group consisting of: a weight scale, a blood pressure measurement device, a glucose sensor, a physiological sensor, an electrocardiogram device, water treatment equipment, a bed scale, an access disconnection device, a bioimpedance measurement device, a pH sensor, lab testing equipment, a blood sample analyzer, and an access flow measurement device.

8. The medical device system according to claim 1 , wherein the distributed database is a first distributed database, and which includes a second distributed database that shares information from at least one medical equipment selected from the group consisting of: a weight scale, a blood pressure measurement device, a glucose sensor, a physiological sensor, an electrocardiogram device, water treatment equipment, a bed scale, an access disconnection device, a bioimpedance measurement device, a pH sensor, lab testing equipment, a blood sample analyzer, and an access flow measurement device.

9. The medical device system according to claim 1 , wherein periodically delivering and retrieving prescription input parameters or treatment output data includes doing so in at least one selected from the group consisting of: real time, a matter of seconds, a matter of minutes, hourly, daily, weekly, monthly, at an end of a treatment, at an end of a treatment day, and at an end of a treatment shift.

10. The medical device system according to claim 1 , which is configured to share operating software between the medical devices via the distributed database.

11. The medical device system according to claim 1 , wherein the distributed database is a first distributed database, and which includes a second distributed database, wherein the logic implementer of at least one of the plurality of the medical devices is programmed to access the second distributed database.

12. The medical device system according to claim 11 , wherein one of the distributed databases is a real time data database.

13. The medical device system according to claim 11 , wherein one of the distributed databases is an administrative data database.

14. The medical device system according to claim 1 , wherein each medical device is programmed to periodically verify the at least one of the prescription input parameters or the treatment output data.

15. The medical device system according to claim 14 , wherein verification is performed via a comparison of hash sums.

16. The medical device system according to claim 1 , wherein the plurality of medical devices are programmed to periodically synchronize the at least one of the prescription input parameters or the treatment output data.

17. The medical device system according to claim 16 , wherein synchronization is performed via a comparison of at least one selected from the group consisting of record identifications, hash sums, and time stamps.

18. The medical device system according to claim 1 , wherein at least one of the medical devices is programmed to display at least one summary screen showing at least one of the prescription input parameters and treatment output data for different medical devices of the system.

19. A medical device distributed database system comprising:
a plurality of medical devices each including a memory, the medical devices including renal failure therapy machines for preforming renal failure treatments;
a first distributed database automatically sharing first data generated or used by a plurality of first medical devices amongst the plurality of medical devices, the memories of the plurality of first medical devices collectively forming the first distributed database; and
a second distributed database automatically sharing (i) second data generated or used by the plurality of first medical devices amongst the plurality of medical devices, (ii) second data generated or used by a plurality of second medical devices amongst the plurality of medical devices, or (iii) second data gene
