Abstract

A system for at least partial closed-loop control of a medical condition is disclosed. The system includes at least one medical fluid pump. The medical fluid pump including a sensor for determining the volume of fluid pumped by the pump. Also, at least one continuous analyte monitor, and a controller. The controller is in communication with the medical fluid pump and the at least one continuous analyte monitor. The controller includes a processor. The processor includes instructions for delivery of medical fluid based at least on data received from the at least one continuous analyte monitor.

Claims

1. A system for at least partial closed-loop control of a medical condition, the system comprising:

at least one medical fluid pump for infusing fluid into a user, the at least one medical fluid pump comprising;

a sensor for determining the volume of fluid infused into the user by the at least one medical fluid pump, wherein the sensor is located directly in an uninterrupted path to the user;

a pumping chamber having an inlet connectable to provide fluid communication with a fluid source, and a pump outlet; and

a force application assembly adapted to provide a compressive stroke to the pumping chamber,

wherein the compressive stroke causes a restriction of retrograde flow of fluid from the pumping chamber through the inlet while urging fluid from the pumping chamber to the pump outlet;

at least one continuous analyte monitor; and

a controller, the controller in communication with the medical fluid pump and the at least one continuous analyte monitor, the controller comprising a processor, the processor comprising instructions for delivery of medical fluid based at least on data received from the at least one continuous analyte monitor.

2. The system of claim 1 wherein the sensor further comprises an acoustic volume sensor.

3. The system of claim 1 further comprising a network operation center, the network operation center in communication with the processor.

4. The system of claim 1 further comprising wherein the force application assembly is coupled to an inlet valve actuator and to a pump actuator, so that the compressive stroke actuates an inlet valve coupled between the inlet and the fluid source to close the valve when the pump actuator causes fluid to be urged from the pumping chamber to the pump outlet.

5. The system of claim 4 further comprising wherein the force application assembly comprises a motor for coordinated operation of the valve actuator and the pump actuator, wherein the motor includes at least one shape-memory actuator.

6. The system of claim 1 wherein at least one of the continuous analyte monitors is a continuous glucose monitor.

7. The system of claim 1 further comprising at least one accelerometer.

8. The system of claim 1 further comprising at least one blood oxygen sensor.

9. The system of claim 1 further comprising at least one inertial measurement unit comprising at least one accelerometer and at least one gyroscope.

10. The system of claim 1 further comprising at least one temperature sensor.
