Storage and supply system for clinical solutions used in an automatic analyzer
A fluid handling system adapted to provide storage and supply of a number of liquid solutions to an automatic clinical analyzer having three different bottle-like containers, a collapsible plastic-metal-plastic pouch having a mouth-like opening, a fitment to be sealed within mouth-like opening a septum within the fitment, and open meal band or cap to seal the septum into the fitment.
1. An automatic clinical analyzer having a fluid handling system for storing and supplying a number of liquid solutions consumed therein, the analyzer comprising:
a reaction carousel supporting reaction cuvettes for containing assay mixtures;
a plurality of probes for supplying sample and reagent mixtures into the cuvettes;
a plurality of assay operational devices that operate on the sample and reagent mixtures in the cuvettes;
a plurality of detector units to perform clinical analytical measurements on the sample and reagent mixtures in the cuvettes;
a plurality of different containers that contain sample and reagent probe cleaners, a system diluent, or a reaction cuvette wash solution, each container having opposed top and a bottom surfaces, the bottom surface includes a front tapered portion with a mounting fin and an opening depending therefrom, each of the mounting fins having a different pattern of at least one open notch therein, each container further including opposed side surfaces and opposed front and back surfaces, the opposed side surfaces having alignment ridges extending therefrom and positioned between a centerline of the side surfaces and the front surface; and
a plurality of container mounting brackets, each bracket having a mating key with a pattern of closed and open sections that match only one of the open notch patterns in the mounting fins so that only one of the different containers can be mounted in each of the container mounting brackets.
2. The clinical analyzer of claim 1 , wherein the alignment ridges are sized to fit into corresponding grooves formed in a mounting bracket.
3. The clinical analyzer of claim 1 , wherein the pattern of at least one open notch comprises a number of overlapping notches.
4. The clinical analyzer of claim 1 , further comprising a collapsible plastic-foil-plastic pouch contained within at least one of the containers.
5. The clinical analyzer of claim 4 , wherein the pouch comprises an opening, a fitment to be sealed within the opening, a septum within the fitment, and a metal cap to seal the septum into the fitment.
6. The clinical analyzer of claim 5 , wherein the fitment comprises a generally cylindrical body having a central bore therethrough, a number of parallel, spaced apart weld sealing foils extending outwardly at a top portion of the body, and a pair of seating ridges extending outwardly at a bottom portion of the body and having a groove formed therein.
7. The clinical analyzer of claim 6 , wherein the weld sealing foils flare outwardly and are tapered to a fin on opposed ends of the weld sealing foils in order to facilitate the integrity of a heat-induced seal within the mouth-like opening of the pouch.
8. The clinical analyzer of claim 5 , wherein the fitment is sized to fit within the opening of the container.
