Abstract

A medical pump for delivering medicament through an IV line to a patient may provide for awareness of the operator and operator authority limiting access by any individual to particular tasks of procedure review, pump programming, pump loading, patient set up, pump operation, and the like associated with the treatment provided by the medical pump. Identifying the operator allows the assignment of particular authority levels to the operators to ensure proper operation of the medical pump, and/or proper operators have made the necessary review to perform the necessary set up of the medical pump facilitating collaborative healthcare delivery. A record of operator intervention and authority levels may be logged to permit an automatic checklist process by the medical pump. Authentication process and pump operation parameters can be communicated through Near Field Communication (NFC).

Claims

1. A programmable medical pump comprising:

a housing;

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

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

a short range communication device configured to not operate wirelessly at distances greater than one meter; and

a mobile device with a user interface including a screen and a keypad communicating through short range communication with the pump to deliver a flow rate and delivery volume of the medicament to operate the pump;

wherein the pump further receives an indication of authorization level associated with a subset of permitted operations of the pump and accepts commands through the mobile device only if those commands are within the subset of permitted operations of the pump associated with the received indication of authorization level; and

wherein pump commands and indication of authorization level must be received from the same, single mobile device.

2. The programmable medical pump of claim 1 wherein the mobile device communicates configuration information for controlling operation of the pump that is selected from a group consisting of operator identity, medicament identity, operating parameter data, and pump configuration data.

3. The programmable medical pump of claim 1 wherein the mobile device is selected from a group consisting of a cellular phone and a tablet computer.

4. The programmable medical pump of claim 1 wherein the mobile device receives configuration information for controlling operation of the pump from a remote electronic database through a wireless network.

5. The programmable medical pump of claim 1 wherein the short range communication device establishes a connection through optical communication between the mobile device and the pump.

6. The programmable medical pump of claim 1 wherein the short range communication device establishes a connection through electromagnetic waves between the mobile device and the pump.

7. The programmable medical pump of claim 1 wherein the short range communication device establishes a connection through radiofrequency waves between the mobile device and the pump.

8. The programmable medical pump of claim 1 further comprising:

a wireless network communication device communicating with a remote electronic database via a wireless network; and

an electronic computer communicating with the mobile device, the at least one sensor, the short range communication device, and the wireless network communication device and executing a stored program fixed in non-transitory media of a computer memory to;

receive through the wireless network communication device electronically readable infusion data comprising prescribed drug data linked to patient identification data and authorization data identifying permitted operation of the pump linked to operator identification data;

receive through the short range communication device electronically readable local drug data from a drug container proximate to the programmable medical pump;

receive local operator identification data identifying an operator proximate to the medical pump;

receive electronically readable local patient identification data identifying a patient proximate to the medical pump;

compare the prescribed drug data with the local drug data and the linked patient identification data with the local patient identification data;

compare the authorization data linked to the operator identification data with the local operator identification data to determine a permitted operation of the pump; and

permit further operation of the pump if the prescribed drug data matches the local drug data and the linked patient identification data matches the local patient identification data and if the operation is permitted.

9. The programmable medical pump of claim 8 wherein the electronic computer further executes the stored program to receive from the short range communication device, electronically readable data comprised of at least one of:

configuration information describing parameters for operating the pump;

route of administration; and

pump status information indicating an operating state of the pump including but not limited to actual sensor reading, actual flow rate, alarm status, volume infused;

pump setup information including but not limited to alarm threshold, sensor enable/disable status, wireless communication enable/disable status, language option, display parameters not limited to contrast and brightness, audio volume level.

10. The programmable medical pump of claim 9 wherein the electronic computer further executes the stored program to:

(a) receive from the short range communication device, data for operation of the programmable medical pump selected from the group consisting of operator identity, medicament identity, operating parameter data, and pump configuration data; and

(b) operate the pump according to information received from at least one sensor and the data received from the short range communication device.

11. The programmable medical pump of claim 9 wherein the electronic computer further executes the stored program to:

(a) receive an input indicating service of the programmable medical pump indicating at least one of inspection of the pump components and repair of the pump components;

(b) monitor at least one sensor to store a reading indicating cumulative flow of material by the pump after receipt of the input indicating service of the programmable medical pump; and

(c) output at least one of a reading indicating cumulative flow of material by the pump and a service indication reminder based on the cumulative flow of material.

12. The programmable medical pump of claim 8 wherein the electronically readable local patient identification data is received from a patient marker proximate to the medical pump through the short range communication device.

13. The programmable medical pump of claim 8 wherein the electronically readable infusion data further comprises an infusion protocol for drug delivery received through the wireless network communication device.

14. The programmable medical pump of claim 8 wherein the linked patient identification data includes but is not limited to a patient ID, Date of Birth, and Name.

15. The programmable medical pump of claim 8 wherein the electronic computer further executes the stored program to:

record the identity of the local operator and at least one of a time of accepting commands from the local operator and the commands accepted from the local operator.
