摘要：
A disposable fluid infusion cartridge (100) comprising a heat exchanger (101) comprising upper and lower faces and an internal heat exchange zone defined by a first and second plurality of overlapping fins (302, 303), which create a substantially uniform tortuous flow path depth, in which each fin has a height ratio with respect to the width of at least 1: 2, whereby the fluid enters the lower face of the heat exchanger (101) through a lower access (106) and fills a lower flow cavity (304) through the width of the heat exchange zone before at least partially flowing through the width of each rear superimposed fin and through the heat exchange zone and outside an upper access (107) on the upper face of the heat exchanger, in which the fluid flowing through the heat exchanger (101) creates a fluid tape, larger in width that in the segments of the linear flow length, for an improved exposure to the inner surface of the heat exchanger (101), characterized in that the disposable fluid infusion cartridge (100) further comprises an air trap (110) comprising upper faces and lower (501, 502) defining a longitudinal axis that extends centrally therebetween, an upper fluid inlet port (503) to receive the fluid from the heat exchanger (101), a lower fluid outlet port (505 ) positioned outside the center of the longitudinal axis, an upper air outlet (504), and a fluid flow disruptor (601) positioned outside the center of the longitudinal axis and next lower fluid outlet access (505), in the that the upper fluid inlet port (503) is positioned outside the center of the longitudinal axis of the air trap (110) to create a vortex of fluid flowing along the longitudinal length of the ai trap re (110) extracting the air downwardly to the lower fluid outlet access (505), and further comprising a purge mechanism for purging the air from the air trap (110) and preventing the air from passing beyond the air trap air (110).Un cartucho de infusión de fluido desechable (100) que comprende un
