Estimating the term…
A fluid processing apparatus for use in conjunction with a prepackaged disposable fluid processing module of the type which includes an integral housing wherein fluid containers, tubing segments, and other components required in processing a fluid are contained, and wherein fluid communication between the containers, components and tubing segments is provided by a fluid circuit formed within the housing by a first relatively inflexible fluid-impervious sheet member and a second relatively flexible fluid-impermeable sheet member. The fluid circuit includes pump and valve elements which operate in response to pressures applied to the second sheet member. Upon installation of the system in the processing apparatus pneumatic actuator ports apply pressures to the second sheet member through access apertures in the housing to circulate fluid through the fluid circuit.
Fluid processing apparatus for use in conjunction with a fluid module of the type including a housing having an access port in a panel thereof;
Fluid processing apparatus for use in conjunction with a disposable flow module of the type including a housing having a bottom panel with an access aperture therein and at least one side panel, a first relatively inflexible fluid-impermeable sheet member positioned within the housing, the first sheet member having an outwardly depressed portion therein which faces the bottom panel, and a second relatively flexible fluid-impervious sheet member positioned within the housing between the first sheet member and the bottom panel and forming in conjunction with the first sheet member a fluid circuit, said fluid processing apparatus comprising:
Fluid processing apparatus for use in conjunction with a fluid module of the type including a housing having an access port in a panel thereof, a first relatively-inflexible fluid-impermeable sheet member positioned within the housing, the first sheet member including an outwardly depressed portion therein which faces the housing panel, and a second relatively flexible fluid-impermeable sheet member positioned within the housing between the first sheet member and the housing panel, the second sheet member forming in conjunction with the depressed portion of the first sheet member a fluid circuit including an element actuable by pressure applied to the second sheet member through the panel access port, said fluid processing apparatus comprising:
