Abstract

A method and apparatus for delivering intravenous drugs to a patient provides for remote loading and programming of IV pumps that may be shipped in a loaded and programmed configuration to a remote site for use with the patient. A special carrier may be provided for pneumatic delivery of the preloaded pump. Password enabled customizing of pump features according to specific user'"'"'s need may be provided to prevent undesired changing of the pump parameters at the remote site.

Claims

1. A method of managing patient drug infusions using a medical pump of a type having a housing;

a pump supported by the housing to receive an IV line therethrough;

at least one sensor supported by the housing to monitor a flow of material through the IV line when received within the medical pump, and an electronic computer supported by the housing and executing a stored program fixed in non-transitory media and communicating with the pump and at least one sensor to allow programming of at least a portion of the pump parameters controlling operation of the medical pump by a first user and to allow selectively restricting the programming of pump parameters by the first user from a second user;

the method comprising the steps of;

(a) receiving by a first individual, at a first work area, an order for a drug infusion providing a drug identification and infusion parameters;

(b) programming the medical pump with the pump parameters;

(c) programming the medical pump to restrict subsequent programming of selected pump parameters by a second user;

(d) transporting the programmed medical pump to a second individual at a second work area remote from the first work area; and

(e) activating the medical pump by the second individual according to its previous programming by the first individual.

2. The method of claim 1 wherein the restricting of subsequent programming parameters hides restricted pump parameters from the second user.

3. The method of claim 1 where the restricting of subsequent programming parameters requires that the restricted pump parameters lie in a range programmed by the first user and blocked from changing by the second user.

4. The method of claim 1 including the step of requiring validation by the second individual at the second work area of at least some pump parameters before activation of the medical pump.

5. The method of claim 4 wherein the pump parameters include patient identification, drug identification, and drug delivery rate.

6. The method of claim 4 wherein the step of validation inputs at least one of patient identification, drug identification, and pump identification using tags attached to at least one of the patient, drug container and pump, the tags selected from the group consisting of bar codes and RFID tags.

7. The method of claim 5 wherein the medical pump is an infusion pump and the drug is contained in an IV bag attached to an IV line and including the step of loading of the medical pump with the drug by threading the IV line through the pump and locking the line into the pump.

8. The method of claim 1 further including the step of loading the pump into a carrier configured to hold the pump and drug during the transporting.

9. The method of claim 8 wherein the medical pump and carrier are sized to fit within a pneumatic air tube delivery system providing a six inch internal diameter.

10. The method of claim 9 wherein the medical pump, drug container and carrier have a weight of less than 12 pounds.

11. The method of claim 1 wherein the medical pump provides a password locking of the programming and including the step of locking the programming performed at step (c) before step (d).

12. The method of claim 11 wherein the medical pump provides a password locking of rules describing a relationship between values of the programming and constraining a reprogramming of the pump by the second individual at the second work area.

13. The method of claim 1 wherein the medical pump includes a communication module and wherein the programming is performed using separate computing device communicating with the medical pump through the communication module through at least one of a wired or wireless connection.

14. A programmable medical pump comprising:

a housing;

a pump supported by the housing to receive an IV line therethrough;

at least one sensor supported by the housing to monitor a flow of material through the IV line when received within the pump;

an electronic computer supported by the housing and executing a stored program fixed in non-transitory media and communicating with the pump and at least one sensor to;

(a) receive from a first individual selectable pump parameters programming an operation of the medical pump;

(b) receive from the first individual permissions restricting subsequent programming of the selectable pump parameters by a second individual;

(c) receive an activation command from the second individual activating the pump to operate according to the pump parameters.

15. The programmable medical pump of claim 14 wherein the permissions hide restricted pump parameters from the second individual.

16. The programmable medical pump of claim 14 where the permissions require that the restricted pump parameters lie in a range programmed by the first individual and blocked from changing by the second individual.

17. The programmable medical pump of claim 14 wherein the electronic computer communicates with a programmable data table providing a listing of a portion of pump parameters controlling operation of the pump, and wherein the electronic computer further executes the stored program to allow programming of the portion of the pump parameters only if a password received from the first individual matches a predetermined password.

18. The programmable medical pump of claim 14 wherein the electronic computer communicates with a programmable data table providing a listing of a portion of pump parameters controlling operation of the pump, and wherein the electronic computer further executes the stored program to allow viewing of the portion of pump parameters only if the password received by the first individual matches a predetermined password.

19. The programmable medical pump of claim 18 wherein the electronic computer further executes the stored program to allow programming of the programmable data table only if the password received from the individual matches the predetermined password.

20. The programmable medical pump of claim 17 wherein the electronic computer further executes the stored program to allow operation of the pump only if entered data parameters are consistent with a set of stored rules describing relationship between parameters.

21. The programmable medical pump of claim 20 wherein the electronic computer communicates with a programmable data table holding the stored rules, and wherein the electronic computer further executes the stored program to allow changing of the rules of the programmable data table only if the password received from the individual matches the predetermined password.

22. A medical pump system comprising:

a medical pump providing a portion for receiving an IV line to pump fluid through the IV line while monitoring fluid pumping under computer control;

a carrier receiving the medical pump when loaded with an IV bag and IV tube for use, the carrier stably supporting the medical pump, IV bag and IV tube for enclosure fitting within a six-inch diameter cylinder.
