HYPOSPRAY
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. It allows medication to be
given through the skin or clothing without mechanical penetration. It
takes one second to remove and one to replace a medicine vial. The air
cartridge is good for 100 injections. It takes one second to remove and
one second to replace the air cartridge. Weight is 1/2 lb. 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 hypsprays 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.
