20120090606 | APPARATUS FOR THE AEROSOLIZATION OF LARGE VOLUMES OF DRY POWDER - The claimed subject matter relates to a device for dosing and aerosolization of aerosolizable material. The device comprises: a body with an aerosolization channel with a distal attachment portion connectable to a source of carrier gas which provides pressure pulses to the aerosolization channel; a proximal attachment portion for outputting aerosolized material and a reservoir for receiving aerosolizable material. The reservoir comprises walls and is connected in a gas-tight manner to the body and in fluid connection with the aerosolization channel. At least part of the walls of the device are self-exciting membranes that can be put into oscillation by the pressure pulses. | 04-19-2012 |

20150197719 | BIOREACTOR AND RACK FOR MOUNTING BIOREACTORS - A bioreactor for preferably three-dimensional cell culturing comprises a scaffold chamber, a first tube, a second tube and a first valve with a scaffold adapter, a tube adapter and a medium adapter. The first valve has a housing with a longitudinal female portion ending in an opening and a longitudinal actuator being arranged through the opening of the female portion of the housing such that the actuator is arranged partially inside the housing and partially outside the housing, wherein the actuator of the first valve is axially moveable relative to the housing of the first valve between a first position in which the first valve is in the operation position and a second position in which the first valve is in the medium change position. By providing the actuators in the first valve which is applied by axial movements, operation of the bioreactor can be comparably simple and safe. In particular, such arrangement allows for a comparably easy identification of the position of the first valve, i.e., e.g., if the valve is in the medium change position or in the operation position. Furthermore, it also allows for exactly adjusting the position of the actuator such that also positions in between the medium change position and the operation position can be conveniently applied if necessary. | 07-16-2015 |
