| insulin pump | A device that delivers a continuous supply of insulin into the body. The insulin flows from the pump through a plastic tube that is connected to a needle inserted into the body and taped in place. Insulin is delivered at two rates: a low, steady rate (called the basal rate) for continuous day-long coverage, and extra boosts of insulin (called bolus doses) to cover meals or when extra insulin is needed. The pump runs on batteries and can be worn clipped to a belt or carried in a pocket. It is used by people with insulin-dependent diabetes. (09 Oct 1997) |
| intra-aortic balloon pump | <cardiology, equipment> A device which is threaded into the aorta that augments the strength of the hearts contraction. The counter pulsation, produced by the inflation of a balloon within the aorta, provides an rhythmic increase in aortic pressures. The net effect is an increase in coronary artery blood flow. Intra-aortic balloon pump is a temporary lifesaving measure that is used to treat severe cardiac damage due to a massive heart attack. (27 Sep 1997) |
| ion pump | A membranal complex of proteins that is capable of transporting ions against a concentration gradient using the energy from ATP. (05 Mar 2000) |
| electrogenic pump | <physiology> Ion pump that generates net charge flow as a result of its activity. The sodium potassium exchange pump transports two potassium ions inward across the cell membrane for each three sodiums transported outward. This produces a net outward current that contributes to the internal negativity of the cell. (05 Jan 1998) |
| jet ejector pump | A suction pump in which fluid under high pressure is forced through a nozzle into an abruptly larger tube where a high velocity jet, at a low pressure in accordance with Bernoulli's law, entrains gas or liquid from a side tube opening just beyond the end of the nozzle to create suction; e.g., the pump by which steam is used to evacuate an autoclave, a water aspirator. (05 Mar 2000) |
| force pump | <machinery> A pump having a solid piston, or plunger, for drawing and forcing a liquid, as water, through the valves; in distinction from a pump having a bucket, or valved piston. A pump adapted for delivering water at a considerable height above the pump, or under a considerable pressure; in distinction from one which lifts the water only to the top of the pump or delivers it through a spout.
