IN-LINE IV DRUG DELIVERY PACK WITH CONTROLLABLE DILUTION
First Claim
Patent Images
1. 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;
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.

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.

8. A method for creating a dilute solution from a drug reagent bed, comprising:
-
introducing fluid into a fluid inlet of a housing;
distributing a first part of the fluid through a drug reagent bed and a terminal frit within the housing;
distributing a second part of the fluid throughout a fluid bypass pathway excluding the drug reagent bed; and
directing both parts of the fluid through a fluid outlet of a housing. - View Dependent Claims (9, 10)
