Manufacture of test strips for e.g. blood glucose determination, comprises transferring test fields from prepared test strip band comprising detection film and adhesive tape, onto carrier tape

摘要

Manufacture of test strips comprises preparing a test strip band (32), comprising a detection film (18) and an adhesive tape (16). Test fields are transferred as self-adhesive test strips (14) from the band (32) onto a carrier tape (12). Manufacture of test strips comprises preparing a test strip band (32), comprising a detection film (18) and an adhesive tape (16). Test fields are transferred as self-adhesive test strips (14) from the band (32) onto a carrier tape (12). A double-sided adhesive tape (16) is used. One side sticks to the film, the other to the carrier tape. The adhesive tape is stabilized by an intermediate film (36) coated on each side with adhesive. The detection film is applied, leaving adhesive side-strips clear on the adhesive tape. A covering layer (20) of woven fabric or fleece forms a planar sample acceptor. It is wider than the test film and sticks to the exposed adhesive edges. The absorbent covering layer is impregnated with a water-repellent outside the detection zone. Impregnation agent is printed on the sides of the detection film, in strip form. The filament structure forming the covering layer is coated by an impregnant. The adhesive tape is processed from roll to roll by a conveyor belt. Various forms of division of the test strips are elaborated. Test strips are stamped or cut out, optionally using a laser cutter. Independent claims are included for: (1) a test strip produced by the method; and (2) equipment for manufacturing the test strip.
