Abstract
An apparatus for mixing a fluid including a storage vessel including a hollow portion for holding the fluid, the hollow portion including at least one access port, the at least one access port adapted to at least one of receive and expel fluid and a diaphragm pump in fluid communication with and removeably coupled to the vessel, the pump adapted to move fluid into and/or out of the hollow portion. Either the vessel or the pump can be disposable. Also, at least one portion of the vessel can be made of a flexible material that takes shape in relation to the contents of the hollow portion. Also, the fluid can be moved between the vessel and the pump by natural or artificial pressure.
Claims23
An apparatus for mixing a fluid comprising:
- a storage vessel including a hollow portion for holding said fluid, said hollow portion including a tapered portion narrowing toward an access port at a bottom of said storage vessel, said access port for receiving and expelling said fluid;
- and
- a disposable diaphragm pump in fluid communication with and removeably coupled to said vessel, said pump for moving fluid at least one of into and out of said hollow portion through said access port, wherein said pump includes a fluid chamber housing, a secondary chamber housing, and a flexible membrane disposed between said fluid chamber housing and said secondary chamber housing, said fluid chamber housing being in fluid communication with said hollow portion, said fluid chamber housing including a radially protruding first flange, said secondary chamber housing including a radially protruding second flange, said first flange being secured to said second flange.
An assembly for mixing a fluid comprising:
- (a) a vessel for holding a fluid, said vessel including at least one flexible portion adapted to change shape to conform to at least a portion of said fluid, said vessel including an access port for receiving and expelling said fluid from a bottom of said vessel;
- and
- (b) a diaphragm pump in fluid communication with said vessel, said pump operable to alternatively
- i) draw fluid from at least one of said vessel and another source of fluid, and
- ii) expel fluid to at least one of said vessel and another destination, said diaphragm pump including a fluid chamber housing, a secondary chamber housing, and a flexible membrane disposed between said fluid chamber housing and said secondary chamber housing, said fluid chamber housing being in fluid communication an inner hollow portion of said vessel.
A system for mixing fluid comprising:
- a storage vessel capable of holding said fluid mixture, wherein at least one portion of said vessel is made of a flexible material that takes shape in relation to the contents of said vessel, said vessel including an access port for receiving and expelling said fluid from a bottom of said vessel;
- and
- a diaphragm pump in fluid communication with said vessel for moving at least a portion of said fluid mixture, wherein said pump includes
- a housing formed by a first portion and a second portion, said first portion including a radially protruding first flange, said second portion including a radially protruding second flange, said first and second flanges secured by a collar,
- a flexible barrier disposed between said first and second portions, and
- at least one chamber inside said pump, said chamber in fluid communication with said vessel.
A method for mixing a fluid comprising:
- providing a storage vessel including a hollow portion for holding fluid, said hollow portion including a tapered portion narrowing toward an access port at a bottom of said storage vessel, said access port for receiving and expelling said fluid,
- providing a diaphragm pump, wherein said pump includes
- a housing formed by a first portion and a second portion, said first portion including a radially protruding first flange, said second portion including a radially protruding second flange, said first and second flanges secured by a collar, said collar threadedly engaged with at least one of said first and second flanges,
- a flexible barrier disposed between said first and second portions, and
- at least one chamber inside said pump,
- coupling said pump to said vessel, said chamber being in fluid communication with said hollow portion,
- filling at least a portion of said hollow portion with a fluid to be mixed,
- initiating said pump to move at least a portion of said fluid to be mixed at least one of into and out of said hollow portion, and
- removing said pump from said vessel.
