Abstract

A medical device, such as an infusion pump, obtains a contextual awareness of its operation by communicating with centralized patient records and or other medical equipment communicating with a common patient, and/or provides real time advisory information, at care point or remotely. A protocol obtained by the medical device from a protocol server provides context-aware protocols and necessary predicate information for those protocols. This predicate information may be discovered by the medical device communicating with electronic medical records and the associated medical equipment.

Claims

1. A medical device comprising:

an interventional element communicating with a patient to perform a medical procedure on the patient;

a data input device for receiving data related to an interventional task performed by the interventional element;

a data communication link for electronic data communication with external devices; and

an electronic controller communicating with the interventional element, the data input device, and a data communication link and executing a stored program to;

(a) transmit the data related to the interventional task to an external data serving device to receive an operation protocol related to the interventional task and an identification of required predicate data;

(b) discover predicate data of the required predicate data from at least one external predicate data device; and

(c) monitor execution of the interventional task according to the received operation protocol and predicate data from the at least one external data serving device and external predicate data device.

2. The medical device of claim 1 wherein the interventional element is a pump for the delivery of a liquid medicament and interventional task is the delivery of liquid medicament

3. The medical device of claim 2 wherein the data related to interventional task includes drug information identifying the liquid medicament and delivery information identifying at least one of the delivery rate and volume for the liquid medicament.

4. The medical device of claim 3 wherein the data related to the interventional task includes patient identification information.

5. The medical device of claim 4 wherein the external predicate data device is a hospital database providing clinical information about the patient based on the patient identification information.

6. The medical device of claim 5 wherein the external predicate data device is a medical monitoring system proximate to the medical pump providing real-time medical data for the patient based on the patient identification information.

7. The medical device of claim 6 wherein the medical monitoring system is selected from the group consisting of:

a blood pressure monitor, a blood oximeter, a glucose monitor; and

a respiration monitor.

8. The medical device of claim 2 wherein the data input device is selected from the group consisting of:

a keyboard, RFID tag reader, and a barcode scanner.

9. The medical device of claim 2 wherein the pump is selected from the group consisting of a large volume infusion pump, a syringe pump, and an ambulatory pump

10. The medical device of claim 2 wherein the data communication link is a wireless communication link.

11. The medical device of claim 2 further including an alarm providing an alarm to a user of the medical pump and wherein the electronic controller further executes the stored program to activate the alarm according to the rules of the protocol.

12. The medical device of claim 2 wherein the protocol identifies blood pressure as predicate data and a protocol that provides a range of blood pressure during which the pump may operate and causes termination of pump operation when blood pressure moves out of this range and wherein blood pressure is obtained through a separate blood pressure monitor operating as the external monitoring device.

13. The medical device of claim 2 wherein the protocol identifies blood glucose as predicate data and a protocol that provides a range of blood glucose during which the pump may operate and causes termination of pump operation when blood glucose moves out of this range and wherein blood glucose is obtained through a separate blood glucose monitor operating as the external monitoring device.

14. The medical device of claim 1 wherein the data communication link is selected from one or more of the group consisting of:

a Bluetooth radio link; and

infrared data link;

a Near Field Communication (NFC); and

a Wi-Fi datalink.

15. A medical pump delivery system comprising:

a medical sensor system providing;

(a) at least one sensor with a patient to obtain medical information on a real-time basis

(b) a first data communication link for electronic data communication with external devices; and

a medical pump system providing;

(a) a pump for the delivery of a liquid medicament;

(b) a data input device for receiving data related to a pump task in delivery of the liquid medicament.

(c) a second data communication link for electronic data communication with external devices; and

(d) an electronic controller communicating with the pump, the data input device, and a data communication link and executing a stored program to;

(i) transmit the data related to the pump task to an external data serving device to receive an operation protocol related to the pump task and an identification of required predicate data;

(ii) discover predicate data of the required predicate data from at least one external predicate data device; and

(iii) monitor execution of the pump task according to the received operation protocol and predicate data from the at least one external data serving device and external predicate data device.

16. The medical pump delivery system of claim 15 further including:

the external data serving device providing a database linking pump task data to protocols and required predicate data for the protocols.

17. A medical device having patient context awareness and/or provides real time advisory information at care point and/or remotely.
