Infusion system disposable alignment system

Abstract

A medical infusion pump pressure plate alignment system and components that include a chassis, a sensor module, and a pressure plate in various embodiments. The pressure plate has a first end pivotally mounted to the chassis of the control module for pivotal retention and a second end selectively mounted to chassis of the control module. The pressure plate, hooks or rail contain recessed or projection features configured for receipt of the complementary features of the sensor module. Additional alignment features can include a retaining component incorporated with the hook, a guide feature on the outer surface of the pressure plate, and a kickstand feature attached to the rail.

1 . A medical infusion pump pressure plate alignment system, comprising:
 a control module including a chassis, the chassis having a first end and a second end;   at least one hinge pin disposed on and adjacent to the first end of the chassis;   a sensor module on the chassis, the sensor module including a planar top surface, with the planar top surface including a sensor channel defining at least two legs; and   a pressure plate having at least one hook and a floor adjacent the at least one hook, wherein the at least one hook is configured to pivotally mount to the at least one hinge pin so that the at least two legs of the planar top surface of the sensor module aligns with and contactingly engages the floor.   
     
     
         2 . The pressure plate alignment system of  claim 1 , wherein the at least one hook comprises a recess and a side wall of the sensor module comprises at least one projection, wherein the recess of the hook is configured to fittingly engage with the projection. 
     
     
         3 . The pressure plate alignment system of  claim 1 , wherein:
 the pressure plate includes a rail substantially surrounding the pressure plate;   the rail includes an inner wall, with the inner wall including at least one male key type projection; and   the sensor module includes an end wall, with the end wall including at least one female key type projection configured to fittingly engage with the male key type projection.   
     
     
         4 . The pressure plate alignment system of  claim 1 , wherein the pressure plate comprises at least one retaining component, the at least one retaining component configured below an underside of the at least one hook forming a void between the underside of the hook and the retaining component, the void dimensioned to complement the at least one hinge pin, wherein one side of the void is open and dimensioned to be slightly smaller than the diameter of the hinge pin.
