A cartridge has test chamber (3); holding chamber (5); separating element (2) to seal fluid volume within holding chamber in airtight manner; measurement cell (8) disposed in upper portion of test chamber; and capillary tube (9) to connect measurement cell to fluid volume, in which air cushion (6) is disposed above the fluid volume and the fluid volume includes test fluid (4). - Independent claims are also included for: - (1) monitoring the function of a device for testing blood platelet function comprising providing a holding chamber, a test chamber, a separating element, a sealing element (15), a measurement cell, and a capillary tube connected to the measurement cell; introducing a fluid volume of a test fluid into the holding chamber; sealing the fluid volume in a substantially airtight manner via the separating element, an air cushion being disposed above the fluid volume; sealing the test chamber in a substantially airtight manner via the sealing element; introducing the measurement cell into the test chamber; moving the capillary tube within the test chamber in the direction of the separating element; piercing the separating element with the capillary tube such that the capillary tube comes into contact with the test fluid; generating underpressure in the measurement cell such that the test fluid flows through the capillary tube and into the measurement cell; measuring a time period associated with when the test fluid stops flowing into the measurement cell; and correlating the measured time period with a predetermined reference value; and - (2) using a test fluid for checking and monitoring the technical functionality of a measurement device comprising providing the test fluid; and measuring a pressure associated with the test fluid in a measurement chamber of the measurement device, in which the pressure measures a physiological process. |
