Abstract

A system for priming an infusion pump is disclosed. The system includes a priming cap including a septum and configured to matably connect with a male part comprising a needle and attached to a length of tubing for fluid, wherein when matably connected with the male part, the priming cap occludes the tubing.

Claims

1. A system for priming an infusion pump comprising:

a priming cap comprising a septum and configured to matably connect with a male part comprising a needle and attached to a length of tubing for fluid, wherein when matably connected with the male part, the priming cap occludes the tubing.

2. The system of claim 1 further comprising a reservoir, wherein the tubing is removably connected to the reservoir wherein fluid from the reservoir is in fluid connection with the tubing.

4. A method for priming an infusion pump assembly comprising:

connecting a male part comprising a needle attached to a length of tubing to a priming cap comprising a septum;

instructing the infusion pump to prime; and

priming the infusion pump into the priming cap.

5. A method for performing an occlusion alarm check comprising:

connecting a male part comprising a needle attached to a length of tubing to a priming cap comprising a septum;

instructing the infusion pump to prime;

priming the infusion pump for a predetermined time into the priming cap;

removing the male part from the priming cap once an occlusion alarm occurs; and

determining an occlusion alarm failure if an occlusion alarm does not occur after the predetermined amount of time.

6. A system for determining a connection to a cannula comprising:

a male part connected to a length of tubing;

a female part fluidly connected to a cannula;

electrical contacts on the male part and the female part wherein, when the male part is connected to the female part, the electrical contacts complete a circuit.

7. The system of claim 6 wherein the length of tubing further comprising one or more wires in electrical connection with the circuit and to an infusion pump and whereby electrical signals are sent to the infusion pump using the wires.

8. The system of claim 7 wherein the infusion pump further comprising a pump processor whereby the pump processor receives the electrical signals.

9. The system of claim 6 further comprising a reservoir in fluid communication with the length of tubing.

10. A system for determining a connection to a cannula comprising:

a male part connected to a length of tubing;

a female part fluidly connected to the cannula;

an RPM chip located on the male part; and

an antenna located on the female part in communication with the MD chip wherein the antenna is in wireless communication with a medical device for indicating whether the male part and the female part are connected.

11. A system for priming an infusion pump comprising:

a male part connected to a length of tubing;

a female part fluidly connected to a cannula;

an RFID chip located on the male part;

an antenna located on the female part in communication with the RFID chip wherein the antenna is in wireless communication with the infusion pump for indicating whether the male part and the female part are connected; and

a pump processor configured to alarm the infusion pump when an instruction prime is received and the male part and female part are connected.

12. A method for preventing prime where a user is connected to an infusion pump comprising:

a pump processor receiving instruction to prime;

a pump processor confirming whether the male part and female part are connected;

where the male part and female part are connected, alarming the user and preventing prime; and

where the male part and female part are not connected, allowing prime.

13. The method claim 12 wherein the alarm is a visual alarm.

14. The method of claim 13 further comprising wherein the alarm is an audio alarm.

15. The method of claim 14 further comprising wherein the alarm is a vibration alarm.

16. The method of claim 12 wherein the alarm is sent to a remote control.
