Subcutaneous and intravenous administration of many types of medication is accomplished with the hypospray. This device employs a pinpoint high-pressure low-volume microscopic aerosuspension stream, which permits low-viscosity medication to be administered through the epidermis without mechanical penetration. Certain types of medications can be formulated for a somewhat wider spray pattern, resulting in lesser penetration into the epidermis, but yielding a higher rate of absorption due to the greater skin area exposed to the drug.
Standard hyposprays are designed to accept a standard medication vial, which can be changed as required. Field hyposprays are normally loaded with an inert saline solution that serves as a vehicle fluid for any of five user-selectable concentrated emergency medication ampules.

Hypospray.
Medical instrument used by Starfleet medical personnel for subcutaneous and intramuscular administration of medication for many humanoid patients. The hypospray uses an extremely fine, high-pressure aerosuspension delivery system, eliminating the need for a needle to physically penetrate the skin.
