Blood testing system and method

A cartridge for insertion into a measuring system, the cartridge comprising:

• measuring chambers comprising at least (i) a first measuring chamber for holding a first sample, and (ii) a second measuring chamber for holding a second sample;
• reagent chambers comprising at least (i) a first reagent chamber for holding at least one first reagent, and (ii) a second reagent chamber for holding at least one second reagent:
• testing chambers comprising at least (i) a first testing chamber for enabling viscoelastic testing to be performed using a first liquid that is based on a mixture of the first sample and the at least one first reagent, and (ii) a second testing chamber for enabling viscoelastic testing to be performed using a second liquid that is based on a mixture of the second sample and the at least one second reagent;
• a first conduit for moving the first sample from the first measuring chamber to the first reagent chamber to bring the first sample into contact with the at least one first reagent, the first conduit having a different three-dimensional structure than the first reagent chamber;
• a second conduit for moving the second sample from the second measuring chamber to the second reagent chamber to bring the second sample into contact with the at least one second agent, the second conduit having a different three-dimensional structure than the second reagent chamber;
• a port in fluid communication with both the first measuring chamber and the second measuring chamber, the port being configured for connection to a source of negative pressure;
• wherein the cartridge inserts into the measuring system at an orientation;
• wherein the first measuring chamber comprises a first opening to receive the first sample and a second opening connected to the first conduit, the first opening being at a first part of the first measuring chamber and the second opening being at a second part of the first measuring chamber, the first part of the first measuring chamber being above the second part of the first measuring chamber when the cartridge is at the orientation;
• and
• wherein the second measuring chamber comprises a third opening to receive the second sample and a fourth opening connected to the second conduit, the third opening being at a first part of the second measuring chamber and the fourth opening being at a second part of the second measuring chamber, the first part of the second measuring chamber being above the second part of the second measuring chamber when the cartridge is at the orientation.
