Abstract: A pneumatic device (1) has at least one venting path (10) for venting the pneumatic device (1) in an outflow direction (R1). The venting path (10) includes a first volume (12), through which a flow can pass, a first compressed-air passage (14), and a sealing mechanism (18). The first compressed-air passage (14) pneumatically connects the first volume (12) to a pressurized part (16) of the pneumatic device (1). The sealing mechanism (18) changes between a normal state (Z1) and a sealing state (Z2). In the normal state (Z1) a flow can pass through the first compressed-air passage (14) both in the outflow direction (R1) and in an oppositely directed inflow direction (R2). In the sealing state (Z2) a flow can pass through the first compressed-air passage (14) only in the outflow direction (R1).

Abstract: A cartridge for holding and ejecting fluid test strips and a test-strip metering device for use with such a cartridge. The cartridge holds the test strips in a sheet-like configuration. The metering device is able to extract test strips from the cartridge in response to an actuation of a single user-interface element. The metering device may test the fluids as each is extracted.

Abstract: Apparatus having a wall and a button arranged in an area of the wall, button actuating means, a switch which is remote from the button actuating means, switch actuating means, and transmission means arranged between the button actuating means and the switch actuating means. The button actuating means is formed by a bell-crank lever which is pivotable about a pivot which is displaced toward the switch in a direction parallel to the wall of the apparatus. The transmission means is formed by a transmission bar supported so as to be movable at least substantially in a direction parallel to the wall and which extends substantially in that direction.
