Abstract: A needle tip protector (80) includes a needle gripping U-shaped clip (81).

Abstract: A needle tip protector (10, 10?) including a pair of apertured members (28, 30 or 28?, 30?) with spring arms (22, 24) urging the apertured members (28, 30 or 28?, 30?) out of alignment to create a barrier to a needle tip (16). A needle gripping U-shaped clip (81) may also provide a needle tip protector (80).

Abstract: A drug-formulating method, a drug commercial-distribution method, and a drug formulation improve safety of a drug that is at risk for abuse—such as methylphenidate, or amphetamine, or an amphetamine-like central-nervous-system stimulant. The drug is formulated into a form (not a transdermal patch) that tends to deter conversion to powder; and in this form commercially distributed, e. g. wholesale or retail. Preferably that form is enclosed in a nontoxic capsule. Preferably the formulating includes dissolving or dispersing the drug into or onto a nontoxic carrier—for example a gel, e. g., methylcellulose, hydroxymethylcellulose, carbomer polymer, or other gelatinous pharmaceutical agent that is FDA-acceptable. Preferably the carrier is water-insoluble, to deter dissolving in water for injection. The carrier may be an oil or a solid—for example paper or other thin medium broadly extended in two dimensions, or a sponge or other medium having generally coarse cellular structure.

Abstract: A drug dosage calculation system includes a hand held, battery operated computing device for use by nurses and other clinical personnel to make calculations pertaining to the drug administration rate and the corresponding flow rate settings of IV systems that are used for intravenous administration of fluids to a patient. Flow rate setting, drug dose rate, drug amount and the amount of IV solution into which the drug is diluted are the primary variables used in such calculations. A keyboard is used to supply data to a computation device that computes the unknown quantity. A display device displays the data input to the computer and also displays data calculated for the unknown variable.
