Abstract: Method and apparatus to determine the speed of sedimentation of blood and other parameters connected thereto, said method being carried out by detecting the development over time of the optical density, or absorbance, of a sample of blood, said sample being sent in the form of a flow inside a capillary container, said detection being made in correspondence with a point of said capillary container and the relative data acquired being processed to obtain said speed of sedimentation and said connected parameters, said method providing to instantly interrupt the flow of the blood sample flowing inside said capillary container, in order to determine a thickening of the red cells in said blood sample and their consequent sedimentation, said detection being made substantially simultaneously with said instant interruption.

Abstract: Method and apparatus to determine the speed of sedimentation of blood and other parameters connected thereto, said method being carried out by detecting the development over time of the optical density, or absorbance, of a sample of blood, said sample being sent in the form of a flow inside a capillary container (12), said detection being made in correspondence with a point of said capillary container (12) and the relative data acquired being processed to obtain said speed of sedimentation and said connected parameters, said method providing to instantly interrupt the flow of the blood sample flowing inside said capillary container (12), in order to determine a thickening of the red cells in said blood sample and their consequent sedimentation, said detection being made substantially simultaneously with said instant interruption.

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 posi
