breast pump

pump (pump)

1. an apparatus for drawing or forcing liquids or gases.

2. to draw or force liquids or gases.

breast pump  a manual or electric pump for abstracting breast milk.

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 enzymatic hydrolysis of ATP.

intra-aortic balloon pump  (IABP) a pump used in intra-aortic balloon counterpulsation.

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 hydrolysis of ATP, by which sodium (Na+) is extruded from a cell and potassium (K+) is brought in, so as to maintain gradients of these ions across the cell membrane.

breast pump

n.

A suction device for withdrawing milk from the breast.

breast pump,

a mechanical or electronic device for withdrawing milk from the breast.

Breast Pump

A tubular mechanical device that provides gentle suction for milk extraction, used when breasts are engorged or when direct infant feeding is not possible for various physical—e.g., prematurity—or logistical reasons

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.

Na⁺-K⁺ pump sodium-potassium 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.
