A mixing apparatus for mixing at least two components comprises a mixing chamber having a first component and at least one component chamber having a further component. The component chamber is connected to the mixing chamber by a feed line. A negative pressure device generates a negative pressure in the mixing chamber in the starting position. By activating the negative pressure device, the pressure is equalized, whereby the further component is transferred into the mixing chamber. A display apparatus is provided at the component chamber to display a pressure change in the component chamber. The display apparatus is preferably formed by elastic bellows provided at one end of the component chamber, which is disposed opposite of the end of the component chamber following the feed line.

Mixing apparatus having display for pressure change

A discharge apparatus for discharging a fluid product comprises a housing () having an outlet () at a front housing end, a discharge member () which is mounted movably in the housing and the rear end of which protrudes from the rear housing end, and a mixing device () for mixing the fluid product inside the housing. The fluid product is provided in a housing volume () formed between the outlet and the discharge member. The fluid product is discharged through the outlet out of the housing by advancing the discharge member inside the housing from a rear position into a front position in the direction of the outlet. The mixing device comprises a mixing tube (), which is mounted movably between the housing and the discharge member in the housing, and at least one mixing element (), which is provided at the front end of the mixing tube and disposed inside the housing volume.

Apparatus for mixing and discharging a fluid product and related system

A bone cement system () is provided having a mixing facility () for mixing and dispensing of bone cement, a reservoir container () for a monomer, and a conveyor (). The mixing facility () has a mixing cylinder (), which stores a bone cement powder. The monomer can be conveyed from the reservoir container () into the mixing cylinder () by the conveyor (). A sieve element is () is arranged between the reservoir container () and the mixing facility (), in order to prevent ingress of the bone cement powder from the mixing cylinder () into the conveyor (). The mixing device () included a dispensing opening () for dispensing a bone cement mixed from the bone cement powder and the monomer. The dispensing opening () includes a shield () having at least one through-opening (). The ratio of the area of the through-opening () to the area of the sieve element () is at least 1 to 3, and the distance between the shield () and the sieve element () is at least 1 mm.

Bone cement system

The invention relates to a teat for feeding bottles, including a receiving head, produced from a dimensionally stable material, and a rubber-elastic suction element. An entry channel leads to the bottle interior and channels lead from there to the outer surface of the receiving head. The suction element, in an initial position, elastically and sealingly rests on at least one section of an outer surface of the receiving head. Milk ducts are located in the contact area between the suction element and the receiving head and communicate with the channels of the receiving head which lead towards the outlet channel in the mouthpiece so that, when a vacuum is produced in the mouthpiece, milk can flow from the feeding bottle through the milk ducts to the outlet channel, the suction element being returnable to its initial position and the flow of milk being interrupted when there is no vacuum.
