1. A wash-free reagent delivery system for introducing a volume of at least one reagent into a reaction containment device in a clinical analyzer, said system including:
- a patient sample supply;
at least one reagent supply;
at least one metering system including a metering head movable between said at least one reagent supply and said reaction containment device;
a first plurality of disposable fluid dispensing tips used to aspirate a volume of reagent from said at least one reagent supply for single-use dispensing into said reaction containment; and
a second plurality of disposable fluid dispensing tips, each of said second plurality of disposable fluid dispensing tips having a sealed dispense end wherein each of the dispense ends of said second plurality of disposable tips are sealed after a quantity of patient sample is initially aspirated therein using said at least one metering system, thereby forming a container.

Abstract
A clinical analyzer for determining the presence or amount of an analyte in a sample includes at least one reagent supply and at least one reaction containment device for containing a volume of sample and a volume of said at least one reagent from said at least one reagent supply. A wash-free delivery system introduces reagent into at least one reaction containment device without requiring washing of delivery components.

2. A clinical analyzer comprising:
-
at least one reagent supply; a patient sample supply; metering system including a metering head that is movable along a metering rail; at least one reaction vessel containing a volume of patient sample dispensed from said patient sample supply and a volume of at least one reagent dispensed from said at least one reagent supply; and a first plurality of disposable metering tips, said first plurality of disposable metering tips each being used by said metering system to aspirate said volume of at least one reagent from said at least one reagent supply and to dispense said volume into the confines of said at least one reaction vessel wherein each said tip of said first plurality of disposable tips includes a dispense end that is placed by said metering system into said at least one reaction vessel and directly into contact with said volume of patient sample contained therein, said patient sample supply further comprising a second plurality of disposable tips, each of said second plurality of disposable tips containing a quantity of patient sample initially aspirated therein using said metering system, each of said second plurality of disposable tips further including a sealed dispense end, thereby forming a container, said sealed dispense end being formed after initial aspiation of patient sample. - View Dependent Claims (3, 4, 11, 12, 13, 14, 15, 16, 17, 18)

5. A clinical analyzer comprising:
-
a sample supply including a first plurality of disposable tips, each of said first plurality of disposable tips having a sealed dispense end forming a container and further having a volume of a patient sample fluid initially contained therein; at least one reagent supply; at least one reaction containment device for containing a volume of patient sample fluid from said at least one sample supply and a volume of reagent from said at least one reagent supply; and reagent wash-free delivery means for aspirating said volume of reagent from said at least one reagent supply and dispensing same into said at least one reaction containment device, wherein said wash-free reagent delivery means includes a second plurality of disposable tips, each of said second plurality of disposable tips being attachable to a metering head movable between said second plurality of disposable tips and said at least one reagent supply for aspirating said volume of reagent from said at least one reagent supply and dispensing aspirated reagent into said at least one reaction containment device, said analyzer further including a third plurality of disposable tips for aspirating patient sample fluid from one of said second plurality of disposable sealed tips and aspirating said volume of patient sample fluid into said at least one reaction containment device. - View Dependent Claims (19, 20, 21, 22, 23)
