摘要:
A device for determining the concentration of analytes in bodily fluids, saiddevicecomprising: a controller module comprising an actuator; a fluid handlingmodule,comprising: a skin piercing fluid collection channel comprising a needle; aninlet chamberconnected to a first end of said skin piercing fluid collection channel; apumping chamber; aconnecting channel connecting said inlet chamber to an inlet end of saidpumping chamber; amembrane connected to said actuator, said membrane forming at least a portionof one wallof said pumping chamber opposite said inlet end of said pumping chamber, saidmembranegel being deflectable in response to movement of said actuator; a sensorchamber including asensor for detecting said analyte; an inlet channel connecting an outlet endof said pumpingchamber to an inlet end of said sensor chamber; a waste channel connected toan outlet endof said sensor chamber; and a vent connected to an outlet end of said wastechannel, such thatsaid pumping chamber is capable of transporting a volume of fluid collected insaid pumpingchamber from said skin piercing fluid collection channel, to said at least onesensor chamberupon deflection of said membrane.
