A Venturi device for introducing a second fluid into a first fluid includes a T-joint, a converging component, and a diverging component. The T-joint component includes a first elongated tube extending along a first direction and a second elongated tube extending along a second direction. The converging component is shaped and dimensioned to slip fit within a first through-opening of the first elongated tube through a first inlet port and has a cross-section that decreases along the first direction from the first inlet port to an inner section of the first though-opening. The diverging component is shaped and dimensioned to slip fit within the first through-opening of the first elongated tube through an outlet port and has a cross-section that increases along the first direction from the inner section of the first though-opening to the outlet port. The converging component is coaxially aligned with the diverging component along the first direction.

The embodiments disclosed herein provide a check valve aspirator including a venturi pipe having a converging section with a converging inlet and a converging outlet, and a diverging section with a diverging inlet and a diverging outlet. The converging outlet is in fluid communication with the diverging inlet. An outlet channel is in fluid communication with the venturi pipe and has an outlet port.

A fluid mixer of the present invention has an element (1) and a chassis (2) that accommodates the element therein and that is engaged with at least both ends of the element, the element having: a first-flow-path forming section (13) at an end of which a fluid inlet (3) is formed and in which a first flow path (4) is formed; and a body section (12) at an end of which a fluid outlet (8) is formed, in which a second flow path (5) is formed, and on an outer circumferential surface of which a plurality of communicating holes (11) are formed so as to allow the second flow path to communicate with the outside. A plurality of delay members (9) are discontinuously formed in a flow-path axial direction on at least one of an inner circumferential surface of the chassis and the outer circumferential surface of the body section, a single continuous space is formed between the inner circumferential surface of the chassis and the outer circumferential surface of the body section, the space serves as a third flow path (6), and the communicating holes serve as branch flow paths (7).

The invention comprises a novel modular, generalizable meso-micro-nano-fluidic platform apparatus, design and methodology which in exemplary embodiments may be applied in conjunction with a novel external triggering and automation/feedback loop control mechanism deployed via computer to explore the phase space of single or double emulsification for applications including the encapsulation of hydrophilic active pharmacological ingredients (APIs). End use applications include the mass production of particulate encapsulation of hydrophobic or hydrophilic APIs with automatic or user-supervised feedback methodology to control and discover mass production or per-drug customized settings of interest for the manufacture of novel or extant therapeutics. This invention allows for a process to produce monodispersed particles of varying sizes and may be used to rapidly screen for optimal size for maximal bioavailability of API particles either on lab bench for in vitro dissolution or in vivo studies, and patient-specific handhelds for maximal drug inhalation.
