A reinforcing member is provided inside the injector body, formed by a metal member to be a tubular member, and extends in an axial direction of the injector body while surrounding at least the igniter and the combustion chamber, the reinforcing member being disposed to be sandwiched between parts of the injector body in a radial direction of the injector body.

A blood treatment device for extracorporeal blood treatment and a method for monitoring the fill level of blood with the blood treatment device. The device includes at least one blood conducting system and at least one chamber container for separating bubbles from the blood to be treated. The device further includes a blood pumping device designed to pump the blood and generate pressure pulses with a predefined frequency in the blood conducting system. The blood treatment device additionally has at least one pressure detection sensor for capturing the pressure pulse introduced by the blood pumping device and a data processing unit designed to derive a fill level parameter from the pressure pulse captured and to modify the state of an information signal as a function of the fill level parameter. At least one alarm device is activated as a function of the state of the information signal.

Disclosed is a cartridge for storing pressurized gas, including a main body with an internal volume for storing a gaseous mixture NO/N.sub.2, and a distribution valve for controlling the output of the gas.
