Abstract

A medical apparatus is provided with a programmable medical device disposed at a first room location and a remote monitor and/or controller disposed at a second room location. The programmable medical device is used to administer a medical treatment to a patient, and the remote monitor/controller may be used to monitor the operation of the medical device, control the operation of the medical device, and/or to transfer data from the medical device to the remote monitor/controller. The apparatus may allow voice communication between the remote monitor/controller and the patient who is receiving treatment via the medical device while the medical device is being monitored and/or controlled from the remote location. The remote monitor/controller may also include means for determining the type of medical device to which it is connected.

wherein said controller responds to said interrupts in accordance with predetermined priorities and wherein said pump priority is assigned the highest priority.

2. An apparatus as defined in claim 1 wherein said means for transferring said data from said infusion pump to said remote monitor comprises means for transmitting said data in segmented, noncontinuous data portions.

3. An apparatus as defined in claim 1 wherein said means for transferring said data from said infusion pump to said remote monitor comprises:

means for repeatedly transmitting portions of said data from said infusion pump to said remote monitor; and

means for generating an interrupt when one of said data portions has been transmitted to said remote monitor, said interrupt causing said transmitting means to transmit another of said data portions from said infusion pump to said remote monitor.

4. An apparatus as defined in claim 1 wherein said means for transferring said data from said infusion pump to said remote monitor comprises:

means for loading a portion of said data into a transmit buffer coupled to said remote monitor via a communication link;

means for generating an interrupt when said data portion has been transmitted from said transmit buffer to said remote monitor via said communication link, said interrupt causing said loading means to transmit another of said data portions from said infusion pump to said remote monitor.

5. A medical apparatus, comprising:

a medical device for administering a medical treatment to a patient, said medical device being disposed at a first room location and comprising;

means for administering said medical treatment to said patient and for generating a signal indicative of the rate of administering of said medical treatment and for generating an administrating interrupt when said administrating signal is generated;

memory means for storing data regarding said medical treatment administered to said patient; and

a controller for controlling said administering means;

a remote monitor for monitoring said medical treatment administered to said patient, said remote monitor being disposed at a second room location remote from said first room location; and

means for transferring said data from said medical device to said remote monitor effective for transferring said data real-time while said medical device is administering said medical treatment to said patient and for generating a transfer interrupt when said data is to be transferred;

wherein said controller responds to said interrupts in accordance with predetermined priorities and wherein said administering priority is assigned the highest priority.

6. An apparatus as defined in claim 5 wherein said means for transferring said data from said medical device to said remote monitor comprises means for transmitting said data in segmented, noncontinuous data portions.

7. An apparatus as defined in claim 5 wherein said means for transferring said data from said medical device to said remote monitor comprises:

means for repeatedly transmitting portions of said data from said medical device to said remote monitor; and

means for generating an interrupt when one of said data portions has been transmitted to said remote monitor, said interrupt causing said transmitting means to transmit another of said data portions from said medical device to said remote monitor.

8. An apparatus as defined in claim 5 wherein said means for transferring said data from said medical device to said remote monitor comprises:

means for loading a portion of said data into a transmit buffer coupled to said remote monitor via a communication link;

means for generating an interrupt when said data portion has been transmitted from said transmit buffer to said remote monitor via said communication link, said interrupt causing said loading means to transmit another of said data portions from said medical device to said remote monitor.

9. An apparatus as defined in claim 5 wherein said medical device comprises an infusion pump and wherein said means for administering said medical treatment to said patient comprises:

a liquid injection device adapted to be connected to the patient;

a conduit connected to said liquid injection device; and

a pumping mechanism for pumping a liquid drug through said conduit and into said patient via said liquid injection devices.

10. A medical apparatus, comprising:

a medical device for administering a medical treatment to a patient, said medical device being disposed at a first room location and comprising;

means for administering said medical treatment to said patient and for generating a signal indicative of the rate of administering said medical treatment and for generating an administering interrupt when said administering signal is generated;

memory means for storing data regarding said medical treatment administered to said patient; and

a controller for controlling said administering means;
