The invention relates to an electrolysis cell (40, 41), in particular for producing an electrically chemically activated sodium chloride solution, comprising an anode chamber (44) provided with an anode and a cathode chamber (42) separated from the former by a membrane (46) and provided with a cathode, the membrane (46) being designed as a hollow ceramic cylinder (18) surrounded by an outer housing (84). The aim of the invention is to permit the production of a particularly high-quality electrically activated sodium chloride solution in a particularly beneficial and reliable manner by means of said electrolysis cell. To achieve said aim, the hollow ceramic cylinder (80) forming the membrane (46) and the outer housing (84) surrounding said cylinder are respectively mounted at the ends in a closure cap (86), which has a central bore (110) forming an entry channel to the interior of the hollow ceramic cylinder (80) that forms the membrane (46) and an annular chamber (112) that runs around said hollow ceramic cylinder and, on the media side, is connected to the interspace between membrane (46) and outer housing (84).
The aim is to specify a gel, more particularly for use in a wound treatment composition, that allows particularly high storage stability and long-term stability to be achieved in conjunction with high microbiocidal activity. For this purpose the gel in accordance with the invention comprises an inorganic silicate as thickener and an electrochemically activated aqueous sodium chloride solution, the electrochemically activated aqueous sodium chloride solution being obtainable by mixing electrochemically activated starting sodium chloride solution, having a free chlorine content of more than 300 mg/l, with distilled water, the conductivity of the electrochemically activated aqueous sodium chloride solution being not more than 12 mS/cm.
The invention relates to a method for generating an electrochemically activated solution by electrolysis of briny water, wherein particularly high shelf life of the anolytes is to be ensured. To this end, a carbonate of sodium is added to the anolytes as a stabilizer.
The aim of the invention is to provide a pharmaceutical composition containing an active ingredient and a carrier substance, wherein the carrier substance comprises an electrochemically activated aqueous sodium chloride solution and is present in a phase separated from the active ingredient, wherein said pharmaceutical composition guarantees an especially long storage life and especially high long-term stability of the composition without unacceptable impairment of the effectiveness of the active ingredient. For this purpose, the carrier substance has a content of free chlorine of more than 500 mg/l, preferably of more than 600 mg/l, according to the invention.
With an installation (1) for producing an electrochemically activated solution having an electrolytic module (2) comprising a plurality of electrolytic cells (40), in which module each electrolytic cell (40) comprises an anode space (44) and a cathode space (42) that is separated from said anode space by a membrane (46), it is intended that particularly high effectiveness of the solution, characterized by a particularly high content of free chlorines, should be achievable along with particularly high storage stability of the solution. For this purpose, according to the invention the cathode spaces (42) of the electrolytic cells (40) are connected in parallel on the media side and the anode spaces (44) of the electrolytic cells (40) are connected in series on the media side.
An electrochemically activated water-based solution obtainable by electrolysis of brine-containing water in an electrolysis module (2) comprising a multitude of electrolysis cells (40) should have a particularly high bactericidal or antibacterial effect combined with particularly long storage stability, i.e. more particularly even after comparatively long storage for, for example, more than two years. According to the invention, such a solution is obtainable by electrolysis of brine-containing water in an electrolysis module comprising a multitude of electrolysis cells (40), in which each electrolysis cell (40) comprises a first electrode space assigned to a first electrical polarity and a second electrode space which is separated therefrom by a membrane (46) and to which a second electrical polarity has been assigned, wherein the electrolyte is supplied to the first electrode spaces (40) of the electrolysis cells serially in the manner of a series circuit.
An electrolysis cell (40), especially for production of an electrochemically activated sodium chloride solution, comprising an anode space (44) provided with an anode and comprising a cathode space (42) which is separated therefrom by a membrane (46) and is provided with a cathode, should enable, in a particularly favourable manner, the production of an electrochemically activated salt solution for which a particularly high bactericidal or antibacterial action, characterized by a high content of free chlorine, coupled with high storage stability is ensured, and the pH should as far as possible allow good combinability with other substances or active ingredients or even be kept adjustable in the manner of a free parameter independently of the other parameters mentioned. For this purpose, the anode, in accordance with the invention, has a coating (92) comprising ruthenium oxide and iridium oxide on its surface. In a system (1) for production of an electrochemically activated solution with a multitude of such electrolysis cells (40, 41), the anode spaces (44) of the electrolysis cells (40, 41) are connected in series on the media side, the surface coating (92) of the anode of each electrolysis cell (40, 41) being selected in each case as a function of the position of the particular electrolysis cell (40, 41) in the series circuit.
A method for room disinfection, in which a disinfectant is nebulized into microscopic droplets, should have both particularly high efficacy of the disinfectant used and particularly high medical compatibility. For this purpose, the disinfectant is an electrochemically activated solution which is obtained by electrolysis of brine-containing water in an electrolysis module (2) comprising a multitude of electrolysis cells (40), in which each electrolysis cell (40) comprises a first electrode space and a second electrode space separated therefrom by a membrane (46), the electrolyte being supplied to the first electrode spaces of the electrolysis cells (40) in parallel and to the second electrode spaces of the electrolysis cells (40) in a series circuit.
