In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.
The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...
A diaphragm micropump uses the repeated actuation of a diaphragm to drive a fluid. The membrane is positioned above a main pump valve, which is centered between inlet and outlet microvalves. When the membrane is deflected upwards through some driving force, fluid is pulled into the inlet valve into the main pump valve.
Structure of diaphragm shown using a 3D medical animation still shot. The thoracic diaphragm, or simply the diaphragm (/ ˈ d aɪ ə f r æ m /; [1] Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle [2] in humans and other mammals that extends across the bottom of the thoracic ...
Examples of the device include the Drinker respirator, the Emerson respirator, and the Both respirator. Iron lungs can be either manually or mechanically powered, but are normally powered by an electric motor linked to a flexible pumping diaphragm (commonly opposite the end of the cylinder from the patient's head).

For children who have GHD, synthetic HGH supports organ development and can help get kids back on a reasonable trajectory of linear growth, says Eisenberg. Taking growth hormone has the potential ...
It is a large, sealed horizontal cylinder (or "tank") in which the patient lies, with their head protruding from a sealed opening at one end of the tank. An air pump or a flexible diaphragm (usually motor-driven) varies the air pressure inside the tank, in continuous alternations, lowering and raising the air pressure in the cylinder. This ...
An example heading into this year's first-round games is SMU traveling from Dallas to State College, Pennsylvania to face Penn State, where it is notoriously known to be cold in December.
