Package deployment of data between a server and a medical device

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.

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.

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.

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 deploying information to a medical device is disclosed. The method includes storing information in a data package on a server, the information intended to be delivered to a medical device. The method also includes receiving a message from the medical device, and in response to receiving the message, indicating to the medical device that information intended for the medical device resides on the server. The method further includes receiving a request for the information, and upon receiving the request, delivering the data package to the medical device.

In a second aspect, a data package delivered from a server to a medical device for affecting operation of the medical device is disclosed. The data package includes information including data for changing the operation of a medical device, the information having a data structure. The data package also includes a server-readable header including size information and lacking information regarding the contents of the data package. The data package further includes a vendor-defined header including data structure information related to the information.

In a third aspect, a system for deploying information to a medical device is disclosed. The system includes a memory configured to store a data package and a programmable circuit interfaced with the memory. The programmable circuit is configured to execute program instructions to store information in the data package, the information intended to be delivered to a medical device. The programmable circuit is also configured to execute program instructions to receive a message from the medical device, and to indicate to the medical device that information intended for the medical device resides in memory. The programmable circuit is further configured to execute program instructions to receive a request for the information and deliver the data package to the medical device.

In a fourth aspect, a method of receiving information by a medical device is disclosed. The method includes initiating a communication session with a medical device server. The method further includes receiving an indication that the medical device server has stored a data package intended for delivery to the medical device. The method also includes requesting the data package and receiving the data package.
