| constant infusion pump | An electrically driven device for delivery from a reservoir of a constant, often very small, volume of solution over a prolonged period of time. (05 Mar 2000) |
|---|---|
| brain-heart infusion agar | A medium used for the isolation of fastidious microorganisms, especially fungi. (05 Mar 2000) |
| home infusion therapy | Use of any infusion therapy on an ambulatory, outpatient, or other non-institutionalised basis. (12 Dec 1998) |
| infusion | The therapeutic introduction of a fluid other than blood, as saline solution, solution, into a vein. (18 Nov 1997) |
| infusion-aspiration drainage | A type of drainage in which antibiotics are continuously infused into a cavity at the same time fluid is being drained (aspirated) from the cavity. Synonym: drip-suck irrigation. (05 Mar 2000) |
| infusion graft | Transplantation by injection of a suspension of cells. (05 Mar 2000) |
| infusion pumps | Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agent and other drugs in thromboembolism, heart disease, diabetes mellitus (insulin infusion systems is also available), and other disorders. (12 Dec 1998) |
| infusion pumps, implantable | Implanted fluid propulsion systems with self-contained power source for providing long-term controlled-rate delivery of drugs such as chemotherapeutic agents or analgesics. Delivery rate may be externally controlled or osmotically or peristaltically controlled with the aid of transcutaneous monitoring. (12 Dec 1998) |
| insulin infusion systems | Portable or implantable devices for infusion of insulin. Includes open-loop systems which may be patient-operated or controlled by a pre-set program and are designed for constant delivery of small quantities of insulin, increased during food ingestion, and closed-loop systems which deliver quantities of insulin automatically based on an electronic glucose sensor. (12 Dec 1998) |
| intravenous infusion | <pharmacology> The giving of antibiotics, blood products, anti-cancer drugs or nutrients into a patients vein over a prolonged period of time. (30 Mar 1998) |
| acid dissociation constant | <chemistry> This is the equilibrium constant for the breaking apart of a weak acid into its hydrogen and conjugate base in a water solution. (09 Oct 1997) |
| Ambard's constant | <physiology> Obsolete law's for output of urea: 1. With the urinary urea concentration constant, urea output varies directly as the square of the concentration of the blood urea. 2. With the blood urea concentration constant, urea output varies inversely as the square root of its urinary concentration. (05 Mar 2000) |
| association constant | <chemistry> Reciprocal of dissociation constant. A measure of the extent of a reversible association between two molecular species at equilibrium. (18 Nov 1997) |
| Avogadro's constant | <physics> The number of molecules in a mole (gram molecular weight) of a substance, equals 6.02 x 1023 molecules. (09 Oct 1997) |
| base dissociation constant | <chemistry> This is the equilibrium constant for the reaction in which a weak base breaks apart in water to form its conjugate acid and hydroxide ion. (09 Oct 1997) |
