Abstract
A suction applying device (10) for applying suction to a sampling unit (50) for sampling bodily fluid, wherein the suction applying device comprises a syringe body (12) with a hollow interior (14) and a piston (20) movable inside the hollow interior of the syringe body. The syringe body has a rear end (16) through which a piston rod (21) connected to the piston extends outside of the syringe body and by means of which the piston can be moved, and a front end (18) opposite the rear end. The suction applying device further comprises a connection arrangement (130) configured for connection of a sampling unit, wherein the connection arrangement is located at the front end of the syringe body. The suction applying device also comprises a first conduit (40) having a rear opening (41) connecting the first conduit to a rear portion (14b) of the hollow interior, in which rear portion a sub-pressure is created when the piston is moved forward inside the hollow interior, and a front opening (42) by means of which the first conduit is connectable to a sampling unit. The suction applying device also comprises a second conduit (46) that connects a front portion (14a) of the hollow interior with …
