Abstract: There is disclosed a heater unit (1600) for conductively heating a removable heat exchanger unit (1602) via a heat transfer surface of the heat exchanger unit, the heater unit comprising: a body portion (1610) for receiving the heat exchanger unit (1602); a flexible heating element (1604) which, in use, makes thermal contact with the heat transfer surface of the heat exchanger unit; a compressible portion (1606) disposed on the distal side of the flexible heating element (1604) relative to the heat exchanger unit (1602) when received; and a biasing arrangement (1608) operable, in use, to distribute a transverse compression force across the arrangement formed from the compressible portion (1606), the heating element (1604) and the heat exchanger unit (1602), whereby the compression force causes the heating element (1604) to be urged towards the heat transfer surface of the heat exchanger unit (1602) and the compressible portion, in conjunction with the compression force, causes the heating element (1604) to co

Abstract: The invention relates to a coupling device for coupling with a tube, comprising at least one pressure element for exerting a clamping force on the tube, wherein the said at least one pressure element is one of a series of correspondingly embodied neighboring pressure elements, wherein each pressure element of said series comprises a first pressure element segment and a second pressure element segment, and wherein the first pressure element segment is placed proximally and the second pressure element segment distally with respect to the tube, and that of each pressure element the first pressure element segment is provided with a protrusion extending transversely to the longitudinal direction of the tube, and that said protrusion extends into a slot that is provided in a directly neighboring second pressure element segment that forms part of a neighboring pressure element.

Abstract: A device for dispensing a fluid comprises a sealed container for the fluid, a carrier for a cartridge with pressurized propellant gas, pressure reducing means, a dip tube for transporting fluid upward out of the container under the influence of the propellant, which dip tube connects to a dispensing channel via a first valve, which can be opened from outside for the purpose of pressing fluid, with the overpressure from the propellant, to the outlet of a dispensing channel, and there dispensing it. A second valve is present between the pressure reducing means and the container for allowing passage of propellant gas to the container in the opened position. An operating handle serves to operate the valve unit, wherein there are three stable positions, i.e. a rest position in which both valves are closed, a standby position in which the first valve is closed and the second valve is opened, and an operative position in which both valves are opened.
