1. A mixing apparatus for mixing at least two components, the mixing apparatus comprising:
a mixing chamber with a first component, at least one component chamber, a feed line connecting the component chamber and the mixing chamber, a closure device that is movable between a closed state in which the closure device blocks the feed line between the mixing chamber and the component chamber, and an open state in which the closure device opens the feed line between the mixing chamber and the component chamber, an ampule containing a second component, the ampule being received in said component chamber, wherein the closure device is coupled to the ampule in the component chamber so as to open the ampule when the closure device is moved from the closed state to the open state, a negative pressure device in order to generate a negative pressure in the mixing chamber so as to transport the second component from the component chamber through the feed line into the mixing chamber, and a display apparatus which is provided on the component chamber in order to indicate a pressure change in the component chamber, the display apparatus comprising an elastic element connected to an opening of the component chamber. |
