Abstract
Abstract An improved system and method of analytical testing for medical purposes including reagent and sample measuring and dispensing by means and steps of forming matrixes of tubes or containers for specimens, applying the specimen to a spectrophotometer for quantitation, recording the results, then routing the chemicals and biological materials to an ion exchanger for final disposition for elimination of problems of pollutants and sediment collection.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
75 words
An improved system for analytical testing for medical purposes comprising a matrix of tubes for reception of serum serum and reagent reagent, means applying a portion of the mixture within the tubes to a spectrophotometer for quantitation, said spectrophotometer being linked to a digital readout device, means passing the mixture from said spectrophotometer through an ion exchanger and membrane filter for final disposition and elimination of pollutants and sediment collection to result in neutralization thereof.
Claim 2
Dependent Claim
75 words
An improved system for analytical testing for medical purposes comprising a matrix of tubes for reception of serum serum and reagent reagent, means applying a portion of the mixture within the tubes to a spectrophotometer for quantitation, said spectrophotometer being linked to a digital readout device, means passing the mixture from said spectrophotometer through an ion exchanger and membrane filter for final disposition and elimination of pollutants and sediment collection to result in neutralization thereof.
Claim 3
Dependent Claim
26 words
The system of claim 1 wherein said ion exchanger and membrane filter receives chemical and biological solutions after use and operation of said analytical testing system.
Claim 4
Dependent Claim
21 words
The system of claim 1 wherein said matrix of tubes is provided with samples of blood for multiple medical chemical testing.
Claim 5
Dependent Claim
55 words
The system of claim 1 wherein said matrix of tubes are positioned so that the tops thereof are adapted to receive fixed amounts of reagents dispensed by entry ports of a holder, said spectrophotometer is provided with a funnel leading into a flow-through cuvette, and said digital readout device provides a digital readout of concentration.
Claim 6
Dependent Claim
26 words
The system of claim 4 wherein said holder has a handle to assist in manually positioning the holder over a row of tubes in said matrix.
Claim 7
Dependent Claim
91 words
The system of claim 1 wherein a dispenser container has a selected and specific reagent, tubing connected to the container to a pump which causes the reagent in metered amounts to egress from the container, a syringe pump for receiving the reagent, and a crank arm connected to a motor to drive the pump, said tubing having a valve to prevent backflow of said reagent, and a bypass exit tube for the purpose of readmitting reagent into the container for those operations in which further reagent is not required for tests.
Claim 8
Dependent Claim
39 words
The system of claim 1 further comprising a row of syringes positioned over a corresponding row of said matrix of tubes, and means to dispense metered amounts of sera into said row of tubes from the row of syringes.
Claim 9
Dependent Claim
40 words
The system of claim 4 wherein said flow-through cuvette leads into a "Y" connection which terminates by emptying into said ion exchanger and membrane filter to purify the waste into a neutral solution for passage into acceptable environmental sewer connections.
Claim 10
Dependent Claim
61 words
Method of improved analytical testing for medical purposes comprising arranging a series of tubes into rows forming a matrix each for receiving sera and reagent, applying a portion of the mixture within the tubes to a spectrophotometer for quantitation, recording the result of the quantitation, passing the resultant mixture to an ion exchanger and membrane filter for final disposition and neutralization.
Claim 11
Dependent Claim
61 words
Method of improved analytical testing for medical purposes comprising arranging a series of tubes into rows forming a matrix each for receiving sera and reagent, applying a portion of the mixture within the tubes to a spectrophotometer for quantitation, recording the result of the quantitation, passing the resultant mixture to an ion exchanger and membrane filter for final disposition and neutralization.
