摘要: An assembly method of an apparatus suitable for pressurized liquid transfusion is disclosed. In one step, a nozzle is to be inserted into the through hole of an elastomeric ring. Because the dimension of the nozzle is larger than the through hole, the internal wall of the elastomeric ring is tensioned and deformed so as to fit the nozzle. In one step, the elastomeric ring along with the nozzle is inserted into a receptacle. The dimension of the outer contour of the elastomeric ring needs to be decreased so as to be accommodated by the receptacle. Due to the flexibility of the elastomeric ring, it resumes at least partially to its original shape. Therefore, proper seal is created and maintained between the elastomeric ring and the nozzle such that leakage and pressure loss may be prevented. The foregoing is capable of working under high-pressured environment for prolonged use.

摘要: An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

摘要: A microstructured passage module for aerosolizer is disclosed. The module includes a plate overlaid by a cover, an entrance, an exit, a plurality of protrusions and a plurality of pillars. The protrusions and pillars project from and are integral parts of the plate. Further, the plate can be divided into a first zone proximate to the entrance and a second zone proximate to the exit. The protrusions are arranged into parallel rows in a direction from the entrance to the exit and form parallel passages therebetween in the first zone for the liquid to flow along. The protrusions in each column are spaced from one another by tunnels. The pillars are interposingly disposed in the second zone and define certain channels therebetween. Moreover, a plurality of pillars further disposed in the passages increase a flow resistance for the liquid flowing through the passages.
