Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A luminescence detection device for quan- tiatively detecting an analyte in a liquid sample, which device comprises (1) a reaction compartment having, along a primary axis, opposite end portions, a first of which is for introduction of fluid reagents and sample into the compartment and the other of which forms a light transmission aperture of predetermined size, the compartment being suitable to hold a composition wnich luminesces in response to contact with analyte-containing sample; (2) closure means in said first end portion for admitting a cannula, whereby fluid is introduced into said compartment, and for closing the reaction compartment; (3) a photoresponsive imaging layer; (4) means for associating the photoresponsive imaging layer and the reaction compartment such that the photoresponsive imaging layer is positioned at a predetermined distance from the end portion forming the aperture so as to be exposed to light emanating therefrom; and (5) means for blocking the photoresponsive imaging layer from exposure to ambient light.
Claim 2
Dependent Claim
158 words
A luminescence detection device for quan- tiatively detecting an analyte in a liquid sample, which device comprises (1) a reaction compartment having, along a primary axis, opposite end portions, a first of which is for introduction of fluid reagents and sample into the compartment and the other of which forms a light transmission aperture of predetermined size, the compartment being suitable to hold a composition wnich luminesces in response to contact with analyte-containing sample; (2) closure means in said first end portion for admitting a cannula, whereby fluid is introduced into said compartment, and for closing the reaction compartment; (3) a photoresponsive imaging layer; (4) means for associating the photoresponsive imaging layer and the reaction compartment such that the photoresponsive imaging layer is positioned at a predetermined distance from the end portion forming the aperture so as to be exposed to light emanating therefrom; and (5) means for blocking the photoresponsive imaging layer from exposure to ambient light.
Claim 3
Dependent Claim
19 words
The device of claim 1 wherein the reaction compartment comprises a reaction vessel housing and a reaction vessel therein.
Claim 4
Dependent Claim
12 words
The device of claim 2 wherein the reaction vessel housing is opaque.
Claim 5
Dependent Claim
11 words
The device of claim 2 wherein the reaction vessel is transparent.
Claim 6
Dependent Claim
16 words
The device of claim 1 wherein the closure means is an integral portion of the compartment.
Claim 7
Dependent Claim
12 words
The device of claim 1 wherein the closure means is a septum.
Claim 8
Dependent Claim
13 words
The device of claim 1 wherein the photoresponsive imaging layer is photographic film.
Claim 9
Dependent Claim
14 words
The device of claim 1 wherein the photoresponsive imaging layer is self-developing photographic film.
Claim 10
Dependent Claim
40 words
The device of claim 1 wherein the means for associating the photoresponsive imaging layer and reaction compartment comprises a base having a horizontal chamber for accepting the photoresponsive imaging layer and, thereabove, a carriage for vertically holding the reaction compartment.
Claim 11
Dependent Claim
23 words
The device of claim 9 wherein the base further comprises a shutter assembly positioned between the reaction compartment and the photoresponsive imaging layer.
