The aerosol formation porous film which possesses the hole structure of specification

摘要

(57) Abstract The nozzle (302) which is formed with the film material of the thin flexibiility where it possesses the multiple holes is disclosed. With one feature, as for the hole, exit aperture diameter in a state where you have not deflected is the range of approximately 2 microns (to be desirable, approximately 1 microns) from approximately 0.5 microns, the material substantial evenly, desirably, making the interval of approximately 50 microns, it is laid out. As for the nozzle (302) desirably, it possesses the profile of conical condition or trumpet condition. In the other aspect of this invention, as for the exit opening of the nozzle (302), in the tubercle field (81) where in order to prevent the fact that the liquid returns to the nozzle (302) the film the outlet side of plane compared to has extended substantially on it is surrounded. When the pharmacy constituent was pushed in into the entrance side of the nozzle (302) mandatorily by using the nozzle (302), it is possible from the outlet side (38) of the nozzle (302) to form the aerosol which includes this constituent. Using this aerosol, it is possible to prescribe the pharmacy constituent to the part where for example the eye or breath organ is chosen. As for the nozzle (302) desirably, containment the medicine formulation the container (5) (1) it is the formative.
