ABSTRACT:
A sub-miniature aerosolizer comprises a substantially elongated sleeve member, a substantially elongated insert and a substantially elongated body member. The sleeve member includes a threaded inner surface which is adapted to receive the insert which is a correspondingly threaded member. The threaded insert provides a substantially helical channel. The body member includes a cavity on its first end which terminates by an end wall at its second end. The end wall includes an orifice extending therethrough. The body member is connected with the sleeve member to provide the sub-miniature aerosolizer of the present invention. The sub-miniature aerosolizer is sized to accommodate insertion into the trachea of a subject for use of the device. For operation of the device, the sub-miniature aerosolizer is connected by a suitable tube with a liquid pressure driver apparatus. The liquid pressure driver apparatus is adapted to pass liquid material therefrom which is sprayed from the sub-miniature aerosolizer. Due to the location of the device deep within the trachea, the liquid material is sprayed in close proximity to the lungs, with resulting improved penetration and distribution of the sprayed material in the lungs.
