Rubidium atoms are stimulated with a second laser beam, a second transmitted reference laser intensity is detected and second reference absorption lines are determined from the second transmitted reference laser intensity. Finally, at least one parameter of the gas or plasma flow is determined from the comparison of the first absorption lines and the second reference absorption lines of the Rubidium atoms.

    • A method and apparatus for aspirating secreted fluids from a wound is disclosed which involves the placement of a drain into a wound via the tissue adjacent the wound. After the wound is closed, a secretion aspiration and collection device, which is connected to the drain via a tube, is placed into operation. The device is designed to have a suction effect controlled between a minimum value and a maximum value according to the quantity of secreted fluid to be aspirated. This is achieved by one or more sensors which control a tube pump. When a second sensor is used, the pump will not be shut off by a passing air bubble in the fluid. A sleeve may also be provided to facilitate introduction of the drain into the wound. Additionally, a needle may be detachably connected to the sleeve to aid the insertion of the sleeve.
