APPARATUS AND CONTINUOUS PROCESS FOR MAKING COAGULATION ASSAY DEVICE.

摘要

A ribbon-like flat web (16) having a plurality of side by side depressions (17) is fed through a horizontal slot having a downward facing surface (28) having an aperture (36) communicating with a reservoir of reagent containing solution. The web (16) is urged against the downward facing surface (28) to provide sealing as the solution is fed into the upward facing depressions (17). The aperture (36) communicating with the reservoir is profiled as a parallelogram having a leading edge (37) which is oblique to the direction of movement. After emerging from the dispensing apparatus (20) the exposed solution is dried in hot air, followed by spray application of a second solution, further drying in hot air, and application of a backing (18) to form capillary chambers. The method is especially useful for manufacturing coagulation assays having magnetic particles and thromboplastin.
