Medical pump

A medical pump for dispensing a liquid, the medical pump comprising:

• a housing comprising an inlet for receiving the liquid and a first outlet for dispensing the liquid;
• a receptacle comprising a chamber and a passage that is in fluid communication with the chamber, wherein the receptacle is received in the housing and is axially movable relative to the housing from a filling position in which the passage fluidly communicates the chamber with the inlet to a first dispensing position in which the passage fluidly communicates the chamber with the first outlet;
• and
• a piston that is received in the chamber and is configured such that, when the receptacle is in the filling position, the piston is axially moveable relative to the receptacle to draw the liquid from the inlet into the chamber, and when the receptacle is in the first dispensing position, the piston is axially moveable relative to the receptacle to dispense the liquid in the chamber through the first outlet,
• wherein the housing further comprises a second outlet, wherein the receptacle is axially movable relative to the housing to a second dispensing position in which the passage fluidly communicates the chamber with the second outlet,
• wherein the piston is configured such that when the receptacle is in the second dispensing position, the piston is axially moveable relative to the receptacle to dispense the liquid contained in the chamber through the second outlet, and
• wherein the medical pump further comprises a detection mechanism configured to:
• determine whether contents of the chamber fulfill a predetermined compression property requirement,
• move the receptacle to the second dispensing position, and then
• move the receptacle and the piston relative to each other to dispense the liquid in the chamber through the second outlet if the predetermined compression property requirement is not fulfilled.
