ATOMIZING DISPENSER FOR ENDONASAL DRUG SPRAY ADMINISTRATION

摘要

distributor for dosing atomizer which endonasale drug solutions. it consists of a main body or the sliding element (1), a piston (12) capable of pumping is introduced by axial sliding in a drug container (5), and a housing and actuator (3).the stem (4) of the pump piston (12) is provided with two grooves and seats (6, 7), each of which contains elastic rings (e) trigger (8, 9) for opposing the pumping stroke of the piston (12) and to regulate it.this control is carried out as the user is required to accumulate enough energy in her hand so as to cause the expansion of the elastic rings (8, 9) to leave, suddenly one after another of the grooves and seats (6, 7), and that they have the run of p iston (12).thus, the variable dose administration is divided into two halves, each of which can be used to separate one of the nostrils of the user. the output is a sudden outburst of the ring energy accumulated and communicated to the pump piston (5), which provides enhanced atomization and perfect the medicated solution.
