Claim 1
Independent Claim
219 words
A device for mechanically spraying a dosage unit of liquid pharmaceuticals or liquid compositions thereof into a body cavity or onto the skin, comprising a valve of a dosage metering pump, an adapter positioned with respect to the said valve in a pressure-tight manner, said adapter having a channel therein, a stem abutting said channel walls with a pressure-tight seal and connecting said channel with the valve of the dosage metering pump so as to prevent a loss of pressure, an adapter vortex spray nozzle connected to said channel for producing an exact and equal distribution of the spray, and a pressure application surface on the adapter for manual operation of the device, said dosage metering pump comprising a first wall of diameter greater than the diameter of said valve of said dosage metering pump, and said adapter comprising a second wall of diameter greater than the diameter of said first wall, said first wall being placed in such a spaced relationship to said second wall that said walls overlap, and a spring means held between and abutting against the inside surface of said second wall and the top surface of said first wall, said spring means being prevented from contacting said stem of the valve of the dosage metering pump by said first wall and said second wall.
