Abstract
Abstract A reactor device includes a receptacle having a lower controlled orifice provided by an imperforate disclike member forming a narrow annular passage which confines materials to the receptacle and passes a liquid from the receptacle at a controlled, uniform rate. The device is applicable to the treatment of human matter such as whole blood or its derivatives and urine, to be analyzed in clinical or industrial laboratories.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
45 words
In a reactor device according to claim 1 wherein one said receptacle and said flow control means includes an imperforate disc member having downwardly and inwardly projecting spaced ribs to hold said flow control disc member closely spaced to said receptacle to define said passage.
Claim 2
Dependent Claim
47 words
In a reactor device according to claim 1 wherein said receptacle has an inturned shoulder with circumferentially arranged ribs extending along its upper surface and upwardly along the sidewall of the receptacle to seat the flow control means closely spaced to the receptacle to define said passage.
Claim 3
Dependent Claim
28 words
In a reactor device according to claim 1 wherein said imperforate control means is generally disclike in shape having a recessed portion along its underside above the orifice.
Claim 4
Dependent Claim
30 words
In a reactor device according to claim 1 wherein said control means is in the form of a generally disclike member removably insertable through the feed inlet into the receptacle.
Claim 5
Dependent Claim
22 words
In a reactor device according to claim 1 including a removable cap to close and seal the feed end of the receptacle.
Claim 6
Dependent Claim
38 words
In a reactor device according to claim 1 including a hollow severable tip portion closed at one end in flow communication with the discharge orifice to permit flow through the orifice upon the severance of the tip portion.
Claim 7
Dependent Claim
32 words
In a reactor device according to claim 7 wherein said receptacle and tip portion are formed as an integral unit, said unit and control member being made of a chemically inert plastic.
Claim 8
Dependent Claim
116 words
A reactor device for ion exchange reactions and the like comprising a tubular receptacle having an upper feed inlet and a lower restricted discharge orifice, said receptacle containing an exchange material for reaction with a liquid delivered into the feed inlet, an imperforate reaction and flow control member in the bottom of the receptacle above the discharge orifice to confine the solid and semisolid portions of the exchange material to the receptacle and defining with the receptacle a narrow annular passage along the inner wall of the receptacle for controlling reaction time in the column and the flow rate of liquid phase reaction products passing by gravity flow past said control member through said discharge orifice.
Claim 9
Dependent Claim
37 words
A reactor device according to claim 9 including a funnel in the feed inlet to pass a feed liquid to the receptacle and a vessel in a flow-receiving relation to the orifice to receive the reaction products.
Claim 10
Dependent Claim
149 words
A reactor device to treat samples of whole blood and the like for laboratory analysis comprising a tubular receptacle having an upper feed inlet and a lower shoulder portion with a restricted discharge orifice, said receptacle containing an ion exchange material for reaction with whole blood delivered into the feed inlet, an imperforate generally disclike reaction and flow control member in the bottom of the receptacle above the discharge orifice to confine the ion exchange material to the receptacle and defining with the receptacle a narrow annular passage along the inner wall of the receptacle for controlling the reaction time in the column and the flow rate of the liquid phase reaction products passing by gravity past said control member through said discharge orifice, said receptacle having downwardly projecting circumferentially arranged ribs on the shoulder portion above the orifice to seat and space the control member in the receptacle.
