Abstract: The present invention provides an intravenous fluid flow regulator 10 for controlling the I.V. administration of medical fluid to a patient. The fluid flow regulator 10 provides a housing 12 having a top 18 and a bottom 20. A flexible diaphragm 14 is positioned within housing 12. A diaphragm holder 16 is provided inside housing 12 for holding a sealing edge 56 of flexible diaphragm 14 in fluid sealing engagement with diaphragm holder 16. The housing 12 and flexible diaphragm 14 define an inlet fluid reservoir 62 and an outlet fluid reservoir 64. The diaphragm holder 16 defines a by-pass fluid channel 54 from inlet fluid reservoir 62, around diaphragm 14, to outlet fluid reservoir 64. The flexible diaphragm 14 being flexible to alternatively move into inlet fluid reservoir 62 and outlet fluid reservoir 64 depending on a fluid pressure differential between inlet fluid reservoir 62 and outlet fluid reservoir 64. A fluid inlet 24 is connected to housing top 18 to provide an inlet fluid passage 27 from an I.V. bag containing medical fluid to inlet fluid reservoir 62. A fluid outlet 34 is connected to housing bottom 20 to provide an outlet fluid passage 44 from outlet fluid reservoir 64 to the patient. At least one rib 48 connected to bottom 20 is provided to prevent movement of flexible diaphragm 14 into outlet fluid reservoir 64 when flexible diaphragm 14 moves into outlet fluid reservoir 64 a predetermined distance.

Abstract: A container for housing a beneficial agent that can be removably coupled to a structure defining a fluid flow path. The container comprises a body defining a first and second interior area separated by a wall that terminates at an opening providing fluid communication between the first and second interior area. A cannula is provided that extends from the body for being removably received by the structure defining the fluid path. The cannula includes an inlet opening and inlet fluid flow path and an outlet opening and outlet fluid flow path. The inlet fluid flow path being in fluid communication with the first interior area, and the outlet fluid flow path being in fluid communication with the second interior area. The second interior area houses the solid beneficial agent and allows fluid that flows through the inlet fluid flow path to pass by at least a portion of the beneficial agent.
