Abstract: The present invention relates to device for quantitative and/or qualitative determination of the presence/absence of a substance in a body liquid comprising a rotatably arranged magazine containing a number of test electrodes intended to be brought into contact with a body liquid to be determined, an arm arranged to influence a test electrode to a relative movement relative to said magazine, whereby the arm comprises contact sheet metals arranged to releasably be fixed to said test electrode and arranged to return said test electrode to the magazine after a finished testing, as well as an arm contained in said device.

Abstract: The present invention relates to a disassemble injection syringe, in particularly suited for diabetics for the administration of insulin, whereby an ampoule part containing a pre-filled amount of injection solution between an injection needle and a plunger, and a dosage of injection solution and mechanism bringing the plunger rod forward, are arranged releasably side-by-side parallel to each other in a first inactive position, and are arranged to be moved parallel axially relative each other adjustment into a coaxial position for an injection cooperation.

Abstract: Apparatus for automatically manufacturing an annular ribbon from stock as, for example, from a reel or roll of such ribbon. A feeding device cuts a length of ribbon dependent upon the preselected size of the annular ribbon, and the apparatus includes a pair of grip members which selectively hold the ends of the ribbon both during the formation of the loop and while the ribbon is being cut from the stock. The grip member rotates so as to cause the two free ends of the ribbon to overlap, thereby permitting the free ends to be secured together as by sewing.
