Infusion Pump Apparatus, Method and System

Abstract

A system is disclosed. The system includes a fill adapter device including a heat exchanger which includes a heating element and a fluid pathway, the fluid pathway fluidly connected to a filling needle input, whereby fluid enters the heat exchanger through the filling needle input and flows through the fluid pathway and whereby the fluid is heated by the heating element. The system also includes a reservoir including a plunger and a plunger rod and a filling needle configured to be removably attached to the reservoir, wherein the fill adapter is configured to be attached to a vial of fluid and wherein fluid from the vial flows through the fluid pathway and is heated and loaded into the reservoir through the filling needle.

         2 . The system of  claim 1 , further comprising a reservoir including a plunger and a plunger rod. 
     
     
         3 . The system of  claim 1 , wherein the fluid pathway fluidly connected to a filling needle input, whereby fluid enters the heat exchanger through the filling needle input. 
     
     
         4 . The system of  claim 2 , further comprising a filling needle configured to be removably attached to the reservoir. 
     
     
         5 . The system of  claim 4 , wherein fluid flows through the fluid pathway and is heated and loaded into the reservoir through the filling needle. 
     
     
         6 . The fill adapter of  claim 1  further comprising a pump to pump fluid into the fluid pathway at a predetermined rate. 
     
     
         7 . The fill adapter of  claim 1  further comprising a check valve for metering fluid into the fluid pathway whereby the rate of flow of fluid through the heat exchanger is controller. 
     
     
         8 . The fill adapter of  claim 1  further comprising a processor for controlling the heating of the fluid according to one or more preprogrammed profiles. 
     
     
         9 . The fill adapter of  claim 1  wherein the filling needle input is a septum. 
     
     
         10 . The fill adapter of  claim 1  further comprising an air trap whereby the air trap allows air to flow out of the heat exchanger. 
     
     
         11 . The fill adapter of  claim 10  wherein the air trap comprising a hydrophobic filter. 
     
     
         12 . A fill adapter device comprising:
 a heat exchanger comprising:
 a pump; 
 a heating element; and 
 a fluid pathway, the fluid pathway fluidly connected to a filling needle input and a vial, whereby fluid from the vial is pumped into the fluid pathway at a predetermined rate and wherein fluid enters the heat exchanger and flows through the fluid pathway and whereby the fluid is heated by the heating element. 
   
     
     
         13 . The fill adapter of  claim 12  further comprising a check valve for metering fluid into the fluid pathway whereby the rate of flow of fluid through the heat exchanger is controller. 
     
     
         14 . The fill adapter of  claim 12  further comprising a processor for controlling the heating of the fluid according to one or more preprogrammed profiles. 
     
     
         15 . The fill adapter of  claim 12  further comprising wherein the fill adapter is configured to be attached to a vial of fluid. 
     
     
         16 . The fill adapter of  claim 12  wherein the filling needle input is a septum. 
     
     
         17 . The fill adapter of  claim 12  further comprising an air trap whereby the air trap allows air to flow out of the heat exchanger. 
     
     
         18 . The fill adapter of  claim 12  wherein the air trap comprising a hydrophobic filter. 
     
     
         19 . A method for atmospheric mitigation in an infusion pump comprising:
 a pressure sensor sending data to a pump processor at a predetermined interval;   determining if the data exceeds an alarm threshold;   if the data exceeds a predetermined alarm threshold, the processor indicating to the user to disconnect from a cannula;   determining if the data meets a pre-determined safe threshold; and   indicating to the user to re-connect to the cannula.
