Publication number: 20260107945Abstract: The present invention provides new storable and stable disinfectant compositions comprising use of a solid precursor of an oxidized state of chlorine. The component in the device is devoid of stability issues, since the solid precursors are instantly to be dissolved in a pharmaceutically-acceptable diluent, adjuvant, or carrier, and combined with an activator (e.g. acetic acid or its salts), optionally combined with a viscosity enhancer, optionally combined with a dye. The main product is generated by breaking or opening seals, barriers or ports between an optional number of compartments in a multi-compartment device to mix the contents in the compartments, followed by gently squeezing or shaking the device to generate the disinfectant solution, wherein the resulting solutions can be taken out through a cap, port or opening on the multi-compartment device.Type: ApplicationFiled: December 18, 2025Publication date: April 23, 2026Inventors: Geir Hermod Almås, Pål Rongved, Thomas Bjarnsholt

Publication number: 20210228818Abstract: The present invention relates to a pre-filled disposable injection device and a needle cannula in combination. The prefilled disposable injection device (1) is made from a housing (2) containing a non-exchangeable cartridge (10) for storing a liquid drug sufficient for a number of injections. The proximal end of the pre-filled injection device (1) carries the dose setting button (3) and the distal end carries the needle cannula (20) having a lumen (21) through which the settable dose is expelled. The distal end (23) of the needle cannula (20) is covered by a telescopic needle covering shield (30) which shield (30) can operate between a first position covering the tip (24) of the needle cannula (20) and a second retracted position allowing an injection to be performed.Type: ApplicationFiled: April 12, 2021Publication date: July 29, 2021Inventors: Henrik Bengtsson, Mads Schenstroem Stefansen, Lars Eilertsen, Henning Graaskov, Claus Moser, Thomas Bjarnsholt
