Abstract

Abstract Indicator device to study the phenomena of blood coagulation, concentration and aggregation of blood platelets and the like including support means (14) bearing test tubes (13) equipped in a plurality of upright hollows (114) provided with very narrow crosswise through holes (214), conveyor means (15) and withdrawal means (17) for said support means (14) to and from an indicator station (11) provided with loading discharging means (16) and including means (27) generating light, photosensor means (28), stirring means (29) and thermostat heating means characterized by the fact that said indicator station (11) comprises a length-wise lodgement (111) for said support means (14) bearing test tubes, whereby said lodgement (111) is equipped with a plurality of holes (226) to convey optical rays and said holes (226) correspond in number, position and advantageously also in diameter to the plurality of said crosswise holes (2147) provided in said support means (14) bearing test tubes positioned in an intermediate position in relation to said conveyor holes (226), and possibly comprising electronic means to coordinate and regulate the working of the conveyor means (15), withdrawal means (17), loading/discharging means (16) and means (18) injecting reagents.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 173 words
Indicator device for studying the phenomena of blood coagulation, concentration and aggregation of blood platelets including: an indicator station defining a lengthwise groove, a plurality of spaced coaxial holes extending crosswise of said groove, a light positioned on a line coaxially extending from each end of a hole on one side of said groove, a photosensor means positioned in an end of each hole on the other side of said groove, a support means defining a plurality of parallel upright hollows for bearing test tubes slidable within said groove and defining coaxial crosswise holes communicating with said hollows and coaxially corresponding to said holes extending crosswise of said groove, said support means also defining holes in the bottoms of said hollows, a conveyor to move said support means to and from said indicator station, loading and discharge means to insert into and remove said support means from said groove, stirring means positioned below each hole in the bottom of each hollow and an injector positioned above said support for loading said test tubes.
Claim 2
Dependent Claim 173 words
Indicator device for studying the phenomena of blood coagulation, concentration and aggregation of blood platelets including: an indicator station defining a lengthwise groove, a plurality of spaced coaxial holes extending crosswise of said groove, a light positioned on a line coaxially extending from each end of a hole on one side of said groove, a photosensor means positioned in an end of each hole on the other side of said groove, a support means defining a plurality of parallel upright hollows for bearing test tubes slidable within said groove and defining coaxial crosswise holes communicating with said hollows and coaxially corresponding to said holes extending crosswise of said groove, said support means also defining holes in the bottoms of said hollows, a conveyor to move said support means to and from said indicator station, loading and discharge means to insert into and remove said support means from said groove, stirring means positioned below each hole in the bottom of each hollow and an injector positioned above said support for loading said test tubes.
Claim 3
Dependent Claim 19 words
The device as in claim 1 wherein said indicator station further defined a substantially closed chamber for said light.
Claim 4
Dependent Claim 12 words
The device as in claim 2 wherein said chamber is substantially spherical.
Claim 5
Independent Claim 19 words
The device as in claims 1, 2 or 3 wherein said photosensor means is longitudinally positionable within the hole.
Claim 6
Independent Claim 28 words
The device as in claims 1, 2 or 3 including means to coordinate and regulate the working of the conveyor means, the loading and discharge means and injector.
