Abstract

The invention relates to systems and methods for communicating with ambulatory medical devices, such as drug delivery devices, both locally and remotely. In one embodiment, a caregiver drug pump communicates with a remote patient drug pump for data gathering, trouble shooting, and operational program changes. The caregiver drug pump is substantially identical in configuration to the patient drug pump. The caregiver drug pump transmits caregiver key input signals to the remote patient drug pump. The patient drug pump receives the key input signals, accesses a desired program, and transmits information for display on the display of the caregiver drug pump. In another embodiment, a computer is provided for communicating locally and/or remotely with a drug pump. The computer may include a display with an image of a pump. The computer may be operated through the use of a mouse or touch screen with respect to the image of the pump, to simulate use of the pump while using the personal computer. The computer may also be used as a training aid for training a caregiver and/or patient how to use the drug pump.

Claims

1. A pump to pump communication system comprising:

(a) a local pump and a remote pump, each of the local and remote pumps including;

(i) a pumping mechanism;

(ii) processor means including means for controlling operation of the pumping mechanism;

(iii) operator input means for making an operator input of information to the processor means;

(iv) display means for displaying information from the processor means; and

(v) a communications cable sensor;

(b) local and remote modems, and local and remote modem cables connecting the respective local and remote modems to the respective local and remote pumps;

(c) modem connect means for connecting the local and remote modems;

(d) first input signal program means associated with the processor means of the local pump for sending an operator'"'"'s input signal from the operator input means of the local pump to the remote pump;

(e) second input signal program means associated with the processor means of the remote pump for receiving the operator'"'"'s input signal from the local pump;

(f) first display signal program means associated with the processor means of the remote pump for sending a display signal from the processor means of the remote pump to the local pump;

(g) second display signal program means associated with the processor means of the local pump for receiving the display signal from the remote pump;

(h) disabling program means associated with the processor means of the remote pump for disabling the pumping mechanism of the remote pump during communication between the local and remote pumps over the modem connect means;

(i) remote pump paging signal program means associated with the processor means of the remote pump for sending an operator'"'"'s input signal from the operator input means of the remote pump to the local pump;

(j) local pump paging signal program means associated with the processor means of the local pump for receiving the operator'"'"'s input signal from the remote pump;

(k) unlock program means associated with the processor means of the remote pump for unlocking access to the processor of the remote pump in response to the operator'"'"'s input signal received from the local pump;

(l) automatic lock program means associated with the processor means of the remote pump for locking access to the processor means of the remote pump after communication between the local and remote pumps over the modem connect means; and

(m) first pump operation program means associated with the processor means of the remote pump for operating the pumping mechanism of the remote pump when the remote pump is disconnected from the remote modem cable.

2. The communication system of claim 1, further comprising second pump operation program means associated with the processor means of the local pump for operating the pumping mechanism of the local pump in a different manner than the remote pump when the local pump is disconnected from the local modem cable.

3. A method of communicating with a remote pump comprising the steps of:

(a) providing a local pump having a keyboard and a display, a local modem, a local telephone, and a local communications cable;

(b) providing the remote pump having a keyboard and a display, a remote modem, a remote telephone, and a remote communications cable;

(c) connecting the local pump to the local modem with the local communications cable;

(d) connecting the remote pump to the remote modem with the remote communications cable;

(e) sending an audible signal from the local telephone to the remote telephone;

(f) sending a keyboard input signal from the local pump to the remote pump;

(g) in response to the keyboard input signal from the local pump in step (f), sending a display signal from the remote pump to the local pump;

(h) displaying the display signal from the remote pump in step (g) on the display of the local pump; and

(i) disconnecting the local and remote communications cables from the local and remote pumps, respectively.

4. The method of claim 3, after step (i), further comprising the step of sending a further audible signal from the local telephone to the remote telephone.

5. The method of claim 3, before step (i), further comprising the step of sending a keyboard input signal from the remote pump to the local pump.

6. The method of claim 3, before step (i), further comprising the step of sending a further keyboard input signal from the local pump to the remote pump, the further keyboard input signal changing an operating program in the remote pump.

7. The method of claim 3, further comprising the step of masking predetermined keys of the keyboard of the remote pump during pump to pump communication.

8. The method of claim 3, further comprising the steps of:

(a) unlocking an access code lock of the remote pump by sending an access unlock keyboard input signal from the local pump to the remote pump; and

(b) relocking the access code lock of the remote pump after pump to pump communication.

9. The method of claim 8, wherein the remote pump includes automatic relock program means for automatically relocking the access code lock, the method further comprising the step of automatically relocking the access code lock.

10. The method of claim 3, wherein the remote pump includes disabling program means for disabling a pumping mechanism of the remote pump, the method further comprising the step of disabling the pumping mechanism of the remote pump during pump to pump communication.

11. The method of claim 3, wherein each of the local and remote pumps includes a communications cable sensor, the method further comprising the steps of:

(a) sensing the remote communications cable with the cable sensor of the remote pump;

(b) sending a signal from the cable sensor of the remote pump to a controller of the remote pump that the remote cable has been sensed;

(c) sensing the local communications cable with the cable sensor of the local pump; and

(d) sending a signal from the cable sensor of the local pump to a controller of the local pump that the local cable has been sensed.

12. The method of claim 3, after step (i), further comprising the steps of pumping fluid to a first patient with the remote pump and pumping fluid to a different patient with the local pump.

13. The method of claim 12, wherein the local and remote pumps each include an operating program for pumping fluid, the operating program used to pump fluid with the local pump being different than the operating program used to pump fluid with the remote pump.
