  2. Diaphragm (structural system) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(structural_system)

    The diaphragm of a structure often does double duty as the floor system or roof system in a building, or the deck of a bridge, which simultaneously supports gravity loads. [1] Parts of a diaphragm include: [2] the collector (or membrane), used as a shear panel to carry in-plane shear

  3. Diaphragm valve - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_valve

    Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic , metal or other materials depending on the intended use.

  4. Thoracic diaphragm - Wikipedia

    en.wikipedia.org/wiki/Thoracic_diaphragm

    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 ...

  5. Diaphragm (mechanical device) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(mechanical_device)

    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.

  6. Negative pressure ventilator - Wikipedia

    en.wikipedia.org/wiki/Negative_pressure_ventilator

    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 ...

  7. Surface tension biomimetics - Wikipedia

    en.wikipedia.org/wiki/Surface_tension_biomimetics

    An extracellular matrix of gel, human alveolar epithelial cells, and human pulmonary microvascular endothelial cells were cultured on a polydimethylsiloxane membrane that was bound in a flexible vacuum diaphragm. Pressurization cycles of the vacuum diaphragm, which simulated breathing, showed similar form and function to an actual lung.

  8. Diaphragm pump - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_pump

    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 ...

  9. Muscles of respiration - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_respiration

    The diaphragm is the major muscle responsible for breathing.It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward).
