Determining online status of a medical device

USPTO Application #: 20090177769
Title: Determining online status of a medical device
Abstract: Methods and systems of patient treatment are disclosed. The methods and systems include use of medical device informatics to modify and validate therapies and drugs used in those therapies. In certain embodiments, a medical device, such as a medical infusion pump, interfaces with a server to administer the patient treatments. In one aspect, a method of determining the on-line status of a medical device is disclosed. The method includes expecting communication from the medical device within a predetermined period, and determining whether a message has been received from the medical device within the predetermined period. The method further includes establishing an on-line status for the medical device based on the determining step. (end of abstract)

The present application claims priority to U.S. Provisional Patent Application No. 60/964,444, entitled “Patient Treatment Systems Employing Medical Device Informatics”, and filed Aug. 10, 2007. That application is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

In general, the present disclosure relates to treatment of patients via systems for use and control of medical devices. More specifically, the present disclosure relates to software for treatment of patients using medical devices.

BACKGROUND

Patients at hospitals and other care centers require controlled therapy administration and monitoring. Hospitals and care centers use a variety of types and brands of medical devices to assist in monitoring and therapy administration. For example, medical devices used to assist in therapy administration may include medical infusion pumps, pulse oximeters, cardiopulmonary monitors, and other therapy delivery and patient monitoring equipment. The various types and brands of medical devices each generally use differing, proprietary communication standards.

The proprietary standards employed by the different devices limit interoperability among the devices, making therapy administration difficult. During use of one or more of the medical devices, a caregiver may want to perform a number of actions related to the medical device. For example, a caregiver may wish to set parameters in a medical device based on the observed characteristics of the patient. Or, the caregiver may wish to view data gathered by a monitor. Due to the proprietary standards used by various medical devices, the caregiver may use a number of types of software and hardware to access the information gathered by the medical device needed to treat the patient.

Coordinating usage of medical devices also can be difficult. A single medical device can be programmed for administering different therapies and in different locations within a hospital. Usage records of multiple medical devices of varying types and in different hospitals may need to be compared. Similarly, the status of a medical device can be difficult to monitor because the devices are often in locations other than where the caregiver is located.

SUMMARY

Methods and systems of patient treatment are disclosed. The methods and systems include use of medical device informatics to modify and validate therapies and drugs used in those therapies. In the various aspects of the present disclosure, a medical device, such as a medical infusion pump, interfaces with a server to administer treatments to patients.

In certain aspects, medical device metadata is used to define a medical device within a medical device network. In further aspects, messages are communicated between a medical device and server to define treatments and other operations to the medical device. In still other aspects, operational and historical data is communicated from medical devices to a medical device server to allow remote monitoring of the administration of a therapy to a patient. In further aspects, timing parameters dictate communication and tracking of events between a medical device and a medical device server.

In a particular aspect, a method of determining the on-line status of a medical device is disclosed. The method includes expecting communication from the medical device within a predetermined period, and determining whether a message has been received from the medical device within the predetermined period. The method further includes establishing an on-line status for the medical device based on the determining step.

In a second aspect, a medical device server is disclosed which includes a memory configured to store on-line status information regarding a medical device and a programmable circuit operatively connected to the memory. The programmable circuit is configured to execute program instructions to expect communication from the medical device within a predetermined period and determine whether a message has been received from the medical device within the predetermined period. The programmable circuit is further configured to execute program instructions to establish an on-line status for the medical device based on the determining step.

In a third aspect, a method of communicating an on-line status of a medical device is disclosed. The method includes initiating communication with a medical device server at a first time, and establishing an on-line status by initiating communication with the medical device server at a second time, the second time within a predetermined period from the first time.
