Abstract

A medical pump provides programming to assist a patient in complying with treatment schedules involving varying dosages of medicament(s). The pump includes stored treatment schedules and protocols that describe control of flow control device(s) for delivering different medicines according to the protocols and which may provide reminders and instructions to the patient.

Claims

1. A programmable medical pump comprising:

a housing holding;

a first and second metering pump wherein

the first metering pump is a syringe pump for receiving and activating a plunger providing delivery of a predetermined first volume of a first medicament from a syringe holding a first medicament;

the second metering pump is a peristaltic pump for receiving and activating actuators controlling delivery of a predetermined second volume of a second medicament through an IV tube attached to a medicament container, the syringe volume being smaller than the medicament container volume;

a controller independently controlling the syringe pump to deliver a first predetermined volume of the first medicament at a first predetermined flow rate and the peristaltic pump to deliver a second predetermined volume of the second medicament at a second predetermined flow rate;

an electronic memory holding a multi-session treatment schedule spanning multiple days describing different treatment sessions and treatment protocols for a delivery of liquid medicament through the syringe pump and peristaltic pump for each session;

an interface display;

a start control; and

an electronic computer communicating with the interface display, start control, syringe pump and peristaltic pump, and an electronic memory executing a stored program fixed in a non-transitory medium to;

(1) identify a current session of the treatment schedule;

(2) provide an alert to a patient indicating the current session is due;

(3) determine a treatment protocol for the current session; and

(4) activate, via the start control, the treatment protocol controlling a sequential delivery of the first medicament at the first predetermined flow rate followed by the second medicament at the second predetermined flow rate for the current session for both the first and second metering pumps;

wherein the interface display communicates with the electronic computer and wherein the electronic computer executes the stored program to display, via the interface display, (i) a calendar to identify a particular session based on a calendar day of the session, (ii) step by step instructions relative to the treatment protocol requiring user intervention, and (iii) a current session of the treatment protocol.

2. The programmable medical pump of claim 1 wherein the interface display displays the reminders.

3. The programmable medical pump of claim 1 wherein the interface display is selected from the group consisting of:

a text display and an image display.

4. The programmable medical pump of claim 1 wherein the current session identifies at least one medicament for the protocol.

5. The programmable medical pump of claim 1 further including a reader reading the treatment protocol from a storage element proximate to the reader.

6. The programmable medical pump of claim 5 wherein the reader is a near field communication reader.

7. The programmable medical pump of claim 1 further including a wireless interface for communicating with a remote electronic device and wherein the electronic computer further communicates with the wireless interface to transfer data related to one of the multi-session treatment sessions.

8. The programmable medical pump of claim 7 wherein the electronic computer further communicates with the wireless interface to report successful completion of each session.

9. The programmable medical pump of claim 1 further including an interface for receiving input from a patient.

10. The programmable medical pump of claim 1 wherein the treatment protocols include amounts of medicine delivery for different sessions.

11. The programmable medical pump of claim 1 wherein the treatment protocols include a sequence of medicament deliveries using the syringe pump and peristaltic pump.

12. The programmable medical pump of claim 1 wherein the treatment protocols provide treatment ranges that may be modified by a patient during treatment.

13. The programmable medical pump of claim 1 further including a code sensor for reading encoded information on an identification device assessable by a patient to confirm the proper patient for the treatment sessions.

14. The programmable medical pump of claim 1 wherein the electronic computer determines that treatment is skipped for the current session.

15. The programmable medical pump of claim 1 wherein the first medicament and second medicament are delivered through a common IV tube.
