A milking machine teat cup is commonly used in the dairy industry for milk extraction.

The teat cup liner is usually formed of rubber or any another elastomeric substance, The liner mouth is sized to receive the cow's teat.

During milking, the cow's teat is inserted into the liner mouth to extend down the liner barrel. A vacuum force is applied to the liner interior via the milk line, and also to a pulsation chamber via the pressure supply connection nipple. Milk is thereby extracted from the teat owing to the pressure difference across the orifice of the cow's teat, and the milk is collected through the milk line. The pulsation chamber is usually periodically opened to atmospheric pressure to cause the liner barrel to collapse, thereby generating a massaging action on the teat from the contracting liner barrel.

The teat cup liner will wear in use and also will become unsanitary. Hence, it is provided as a removable/disposable component of the teat cup. For ease of fitting and removal within the teat cup shell.

When using a typical milking machine which includes teat cups , dairy producers are faced with the challenge of preventing the transmission of organisms that cause bovine mastitis, an inflammation of a cow's mammary glands. A mild case of mastitis in a cow can merely reduce milk production, while in a severe case, it may result in the death of the cow. Some of the organisms which cause mastitis are highly contagious, and are easily spread from cow to cow when a milking machine is transferred from one cow to another during milking. Thus, a mastitis outbreak can rapidly spread through a herd and devastate its milk production.

Proper sanitation of milking machines is therefore critical to mastitis control. Milking machines are typically cleaned using hot water, detergents, and disinfectants two or three times per day, corresponding to the milking frequency of the herd, so that the machines will theoretically be free of the organisms that cause mastitis. However, since milking machines are rarely cleaned between milking individual cows, mastitis-causing organisms can be easily transferred between cows during a milking session.

Devices which clean teat cups between the milking of individual cows require "backflush" rinsing systems. These have not been widely adopted because they are expensive to install and maintain, and they require large amounts of water and disinfectants for operation. Additionally, they are not always effective in removing bacteria populations from the teat cup line.

The atmosphere air intake end of pulsation chamber is connected to the Hydodrive Synthesizer wave guide and the other end of the wave guide exposed to the atmosphere.

As the air is drawn into the pulsation chamber, the air is excited and the cold plasma destroy common mastitis-causing bacteria, such as Streptococcus agalactiae, Staphylococcus aureus, and Corynebacterium bovis, as well as common environmental bacteria (e.g., those commonly found in bedding material and feces, such as streptococci, enterococci, and coliforms) which may contaminate milk, or which may also cause mastitis or other conditions.

It is expected that the milking machine may be particularly useful in destroying hardy organisms that are resistant to antibiotics and other treatments, such as Pseudomonas aeruginosa, Actinomyces pyogenes, and Mycoplasma bovis, which at this time can usually only be eliminated by culling infected cows from the herd.

The milk extracted from the cows could also be passed through a Hydrodrive Synthesizer before shipment fpr destroying the bacteria in the milk .

The Hydrodrive Synthesizer could also be used to treat the water used for back wash of the teat cups for destroying the E-Coli and other bacteria in the water as per details at:
