pump

 [pump]
1. an apparatus for drawing or forcing liquid or gas.
2. to draw or force liquids or gases.
blood pump a machine used to propel blood through the tubing of extracorporeal circulation devices.
breast pump a pump for taking milk from the breast.
calcium pump the mechanism of active transport of calcium (Ca2+) across a membrane, as of the sarcoplasmic reticulum of muscle cells, against a concentration gradient; the mechanism is driven by hydrolysis of ATP.
enteral feeding pump an infusion pump specifically designed for administration of a solution through a feeding tube.
insulin pump see insulin pump.
intra-aortic balloon pump see intra-aortic balloon pump.
muscle pump compression of veins by the contraction of skeletal muscles, forcing blood towards the heart against the flow of gravity; seen particularly in the deep veins of the lower limbs. Called also venous pump.
proton pump a system for transporting protons across cell membranes, often exchanging them for other positively charged ions.
sodium pump (sodium-potassium pump) the mechanism of active transport driven by the energy generated by Na+,K+-ATPase, by which sodium (Na+) is extruded from a cell and potassium (K+) is brought in, so as to maintain the low concentration of sodium and the high concentration of potassium within the cell with respect to the surrounding medium. A high concentration of intracellular potassium is necessary for vital processes such as protein biosynthesis, certain enzyme activities, and maintenance of the membrane potential of excitable cells. Called also Na+-K+ pump.
stomach pump see stomach pump.
venous pump muscle pump.

blood pump

1 a device for regulating the flow of blood into a blood vessel during transfusion.
2 a component of a heart-lung machine that pumps the blood through the machine for oxygenation and then through the peripheral circulatory system of the body. Also called mechanical heart-lung. See also cardiopulmonary bypass, oxygenation.

blood pump

1. A device for pumping blood. It is attached to an extracorporeal circulation system.
2. A compression sleeve placed about a plastic transfusion bag.

2. to draw or force liquids or gases.
3. a mechanism or structure that mediates active transport of ions or molecules across a biological membrane.

blood pump
a machine used to propel blood through the tubing of extracorporeal circulation devices.
calcium pump
the mechanism of active transport of calcium (Ca2+) across a membrane, as of the sarcoplasmic reticulum of muscle cells, against a concentration gradient; the mechanism is driven by hydrolysis of ATP.
infusion pump
an electronic device used to control the administration of intravenous fluids in very small amounts and at a carefully regulated rate over long periods.
pump oxygenator
heart-lung machine. See extracorporeal circulatory support unit.
sodium pump, sodium-potassium pump
the mechanism of active transport driven by hydrolysis of ATP, by which sodium (Na+) is extruded from a cell and potassium (K+) is brought in, so as to maintain the low concentration of Na+ and the high concentration of K+ within the cell with respect to the surrounding medium. See also na+,k+-atpase.
stomach pump
an apparatus used to remove material from the stomach. It consists of a rubber stomach tube to which a bulb syringe is attached. The tube is inserted into the mouth or nose and passed down the esophagus into the stomach. Suction from the syringe brings the contents of the stomach up through the tube. For cattle and horses a reversible metal pump adapted from a yachting bilge pump is most suitable. In small animals, gravity is the usual method of moving fluid into and out of the stomach during lavage.
