Abstract

Abstract A sample processor card for use with a centrifuge in which the direction of centrifugal force can be altered at will, wherein the card includes a supply of chemical reagent and inlet means for supplying a chemical sample to the card. The sample is advanced under centrifugal force through capillary means to sample measuring means, and the measured sample is then mixed with reagent to permit a chemical test to be carried out on the reagent, all under centrifugal force.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 114 words
A sample processor card for carrying out chemical tests under centrifugal force comprising a substantially closed card and a supply of reagent in the card, said card including inlet means for supplying a sample to the card, capillary means communicating with the inlet means to receive sample, overflow means communicating with the capillary means to receive excess sample under the effect of centrifugal force applied to the card, holding chamber means adapted to receive, in response to centrifugal force acting on the card, reagent and sample from the capillary means, and cuvette means communicating with the holding chamber means and adapted to permit measurement of the chemical reaction between the reagent and the sample.
Claim 2
Dependent Claim 114 words
A sample processor card for carrying out chemical tests under centrifugal force comprising a substantially closed card and a supply of reagent in the card, said card including inlet means for supplying a sample to the card, capillary means communicating with the inlet means to receive sample, overflow means communicating with the capillary means to receive excess sample under the effect of centrifugal force applied to the card, holding chamber means adapted to receive, in response to centrifugal force acting on the card, reagent and sample from the capillary means, and cuvette means communicating with the holding chamber means and adapted to permit measurement of the chemical reaction between the reagent and the sample.
Claim 3
Dependent Claim 29 words
A card as defined in claim 1 which includes sample separating chamber means communicating with the capillary means and adapted to separate, under centrifugal force, constituents of the sample.
Claim 4
Dependent Claim 42 words
A card as defined in claim 1 which includes sample measuring chamber means communicating with the capillary means and adapted to receive a measured quantity of sample from the capillary means in response to the application of centrifugal force to the card.
Claim 5
Dependent Claim 34 words
A card as defined in claim 3 which includes sample overflow chamber means positioned to receive sample in excess of that filling the sample measuring chamber means and adapted to retain such excess sample.
Claim 6
Dependent Claim 29 words
A card as defined in claim 1 wherein the supply of reagent in the card includes means for dispensing reagent in response to centrifugal force applied to the card.
Claim 7
Dependent Claim 26 words
A card as defined in claim 5 wherein the means for dispensing reagent includes means for dispensing reagent and means for dispensing diluent for the reagent.
Claim 8
Dependent Claim 62 words
A card as def ined in claim 5 wherein the means for dispensing reagent includes reagent chamber means adapted to contain the reagent and strippable sealing means closing the reagent chamber means whereby the sealing means is stripped from the reagent chamber means in response to the application of centrifugal force applied to the card to release reagent from the chamber means.
Claim 9
Dependent Claim 42 words
A card as defined in claim 7 which includes diluent chamber means positioned adjacent to the reagent chamber means, the sealing means closing the reagent chamber means and the diluent chamber means whereby the application of centrifugal force releases reagent and diluent.
Claim 10
Dependent Claim 39 words
A card as defined in claim 8 wherein the reagent chamber means is positioned forward of the diluent chamber means whereby the reagent is released prior to the release of diluent in response to the application of centrifugal force.
Claim 11
Dependent Claim 54 words
A card as defined in claim 7 which includes means for securing to the card the sealing means whereby the application of centrifugal force to the card displaces the reagent chamber means in the direction of the centrifugal force to strip the sealing means from the reagent chamber means to thereby release the reagent.
