SYSTEMS FOR IMMUNOASSAY TESTS

This invention relates to an apparatus for conducting immunoassay test. The apparatus includes a groove unit having a groove along a vertical direction configured to hold a rod-shaped portion of a probe along the vertical direction, and a push pin configured to move along a horizontal direction, the push pin being capable of residing at a first position and a second position. A tip of the push pin is capable of pressing the rod-shaped portion of the probe against the groove when the push pin resides at the first position. The distance between the tip of the push pin and the groove is larger than a diameter of the rod-shaped portion of the probe when the push pin resides at the second position.

POINT OF CARE TEST CARTRIDGE

A test cartridge for evaluating biological fluids can have a sensor flow cell defining a flow path for selectively passing a test fluid or biological fluid across a sensor to evaluate the sensor or the biological fluid. The test cartridge can include a sample port and at least one deformable reservoir, both formed as part of the test cartridge and fluidly connected to the flow path upstream of the sensor. A biological fluid can be manually fed into the flow path through the sample port for evaluation by the sensor. Before the biological fluid is fed through the sample port, the deformable reservoir can be manually ruptured to pass the test fluid contained within the reservoir across the sensor to first evaluate the sensor. In an example, the deformable reservoir can include a first reservoir containing a liquid quality control (LQC) fluid and a second reservoir containing a calibration fluid.

THERMALLY DRAWN SENSOR DEVICE AND A METHOD OF FABRICATION THEREOF

One aspect of the present invention relates to a method of fabricating a chemically active fibre device (1) by thermal drawing. The method comprises the steps of providing a preform, the preform comprising a support element (3) at least partially made of a first polymeric material; and carrying out a thermal drawing process of the preform to produce a thermally drawn fibre. The preform comprises one or more chemically active agents and/or biological materials configured to react with a fluid sample when the one or more chemically active agents and/or biological materials are in contact with the fluid sample. In this manner miniaturised lab-in-fibre devices can be fabricated.

ADAPTER FOR BLOOD DISPENSING

A medicine-holding body is disposed in a flow path of a nozzle portion of an adapter for blood dispensing. The medicine-holding body is formed of a plurality of fibers which is made of polyester and is bundled by aligning a longitudinal direction thereof in a flowing direction which is a direction in which blood flows. The medicine-holding body holds an anticoagulant for suppressing coagulation of blood, as a medicine to be mixed into blood. The surface area of the medicine-holding body is greater than or equal to 10 mm.sup.2 and less than 600 mm.sup.2. In a case where the surface area of the medicine-holding body is greater than or equal to 10 mm.sup.2, the concentration of the anticoagulant becomes greater than or equal to a lower limit value of 10 U/mL even under most severe conditions such as a dispensing speed of 500 L/second. In a case where the surface area of the medicine-holding body is less than 600 mm.sup.2, it is possible to maintain the occurrence rate of hemolysis to be less than or equal to 10%.
