Mitral valve prolapse, with significant regurgitation (abnormal backflow of blood).

A backflow preventer including a primary port, forward port, and return port supports bi¬ directional fluid transfer with the well.

Reflux is graded on a scale from I-V based on the degree of urine backflow.

A disconnector means (32) for the electric supply of electric members of the vehicle is actuated by the displacement of the support with respect to the body of the vehicle in case of an impact.

The arrival of water from the local preparation of the body is equipped with a system separator avoiding any contamination of public drinking water supply network.

The complete hose disconnector is then released from the fixation cylinder and ready to be re-used to install a new foundation.

The arrival of water from the local preparation of the body is equipped with a system separator avoiding any contamination of public drinking water supply network.

The arrival of water from the local preparation of the body is equipped with a system separator avoiding any contamination of public drinking water supply network.

The present invention relates to an unpowered small-volume heating boiler and to a backflow-preventing apparatus for the unpowered small-volume heating boiler.

The arrival of water from the local preparation of the body is equipped with a system separator avoiding any contamination of public drinking water supply network.

It comprises two, noninterchangeable, hose connections: one connector ensures oil flow to the fixation cylinder, the second one operates the disconnector itself.
