| knee cap dislocation | <orthopaedics> A dislocation of the knee cap most often occurs with the knee cap moving laterally (toward the outer aspect of the leg). Features include a partially flexed knee joint with obvious displacement of the knee cap laterally. Reduction is accomplished with knee joint extension and gently coaxing the knee cap back to the midline. (17 Dec 1997) |

| adrenal cortex injection | An obsolete treatment involving the parenteral administration of extract of the adrenal cortex; formerly used in treatment of Addison's disease. (05 Mar 2000) |
| bolus injection | <procedure> The injection of a drug (or drugs) in a high quantity (called a bolus) at once, the opposite of gradual administration (as in intravenous infusion). (18 Nov 1997) |
| regular insulin injection | A preparation that may contain 20, 40, 80, 100, or 500 USP insulin units per ml, although the trend is toward standardizing all insulin preparations at 100 units per ml; it is administered subcutaneously, occasionally intravenously, and has a rapid onset of action, has a brief duration (5 to 7 hours), and is compatible for mixing with long-acting insulin preparations; used in the treatment of diabetic acidosis and insulin coma. Synonym: regular insulin injection. (05 Mar 2000) |
| Ringer's injection | A sterile solution of sodium chloride, potassium chloride, and calcium chloride, containing in each 100 ml between 820 and 900 mg of sodium chloride, between 25 and 35 mg of potassium chloride, and between 30 and 37 mg of calcium chloride; used intravenously as a fluid and electrolyte replenisher. (05 Mar 2000) |
| water for injection | Water purified by distillation for the preparation of products for parenteral use. (05 Mar 2000) |
| collagen injection | Correction of superficial soft tissue deformities, acne scars, or age-related skin changes by injection (implantation) of collagen; bovine collagen preparations are commonly used. Prior intradermal testing is necessary to exclude hypersensitivity. (05 Mar 2000) |
| selective injection | Injection of contrast medium following selective catheterization of a branch artery or vein for angiography. (05 Mar 2000) |
| sensitizing injection | An injection that sensitises a person so that subsequent exposure to the antigen (allergen) evokes an allergic response. (05 Mar 2000) |
| hypodermic injection | The administration of a remedy in liquid form by injection into the subcutaneous tissues. Synonym: hypodermic. (05 Mar 2000) |
| neutral beam injection | <radiobiology> This is one of the fundamental plasma heating methods. A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV), the ion beam is then passed through a neutral gas region, where the ions neutralise via charge-exchange reactions with the neutral gas. The neutralised beam is then injected into a magnetically confined plasma. The neutral atoms are unaffected (not confined) by the magnetic field, but ionize as they penetrate into the plasma. The high-energy ions then transfer some of their energy to the plasma particles in repeated collisions, and heat the plasma. (09 Oct 1997) |
| subcutaneous injection | The delivery of a medication into the subcutaneous tissues via injection (for example insulin). (27 Sep 1997) |
| depot injection | An injection of a substance in a vehicle that tends to keep it at the site of injection so that absorption occurs over a prolonged period. (05 Mar 2000) |
| injection | <procedure> The act of forcing a liquid into a part, as into the subcutaneous tissues, the vascular tree or an organ. Compare: infusion. Origin: L. Injectio, from inicere = to throw into (18 Nov 1997) |
| injection flask | A denture flask designed so as to permit the forced flow of denture base material from a reservoir into the mold after the flask is closed and during curing. (05 Mar 2000) |
