SPRAY DISPENSER FOR SPRAY ADMINISTRATION OF NASAL CAVITY INTERNAL MEDICINE

摘要

PURPOSE: To provide a spray dispenser capable of dividing the dosage of nasal cavity internal medicine into halves to be sprayed and administrated. ;CONSTITUTION: A spray dispenser has a body or a slider 1, a piston/pump 12 axially slidable in a medicine vessel 5, and a push button/housing 3, the piston/ pump 12 comprises two grooves/sheets 6, 7 on its stem 4, the grooves/sheets respectively retain the elastic detent rings 8, 9, and these elastic detent rings 8, 9 resist against the stroke of the piston/pump 12 to control the same. The stroke of the piston 12 is divided to generate the separated medicine spraying supply to each nasal cavity of an user for each time, and the snap action instantaneously releases the accumulated energy to the piston/pump 5 to generate the complete servo support spraying of the chemical solution.;COPYRIGHT: (C)1994,JPO
