Abstract
An in-line drug delivery pack that connects in-line with an intravenous (IV) line and allows for the mixing of diluent with a drug reagent to be delivered to the patient. An internal drug bed bypass mechanism is tailored to apportion diluent flow between the bypass and the drug bed. The apportionment is selected to achieve a solution concentration suitable for IV administration as the dried reagent is dissolved. Thus, both dissolution and precisely tailored dilution are performed in the same simple device.
Claims20
A drug delivery apparatus comprising:
- a housing having an inlet port, an outlet port, and at least one terminal frit;
- a drug reagent bed within the housing, the drug reagent bed in communication with a first fluid flow path between the inlet port and the outlet, wherein the drug reagent bed comprises reagents for the preparation of a solution suitable for intravenous administration;
- and
- a second fluid flow path within the housing between the inlet port and the outlet port, wherein the second fluid flow path bypasses the drug reagent bed.

A drug delivery apparatus comprising:
- a housing having an inlet port and an outlet port, wherein a plurality of elements housed within the housing are selected to tailor relative flow rates along the first and second paths to control a concentration of solution formed from diluent and the drug reagent bed;
- a drug reagent bed within the housing, the drug reagent bed in communication with a first fluid flow path between the inlet port and the outlet;
- a second fluid flow path within the housing between the inlet port and the outlet port, the second fluid flow path bypassing the drug reagent bed.
A drug delivery apparatus comprising:
- a housing having an inlet port, an outlet port, and at least one terminal frit, and at least one compression component;
- a drug reagent bed within the housing, the drug reagent bed in communication with a first fluid flow path between the inlet port and the outlet, wherein the drug reagent bed comprises reagents for the preparation of a solution suitable for intravenous administration, and the compression component is positioned within the housing to exert pressure on the reagent bed;
- and
- a second fluid flow path within the housing between the inlet port and the outlet port, wherein the second fluid flow path bypasses the drug reagent bed.
