Abstract: The present invention describes a transparent gel containing at least one gelling agent and an aqueous sulfuric acid solution containing 10 mg to 50 mg zinc and 5 mg to 35 mg iron, each based on 1 kg gel. The aqueous solution has a pH between 3.0 and 2.0 and contains 100 mg to 1000 mg polyhexamethylene biguanide (PHMB) based on 1 kg gel.

Abstract: The invention relates to a treatment solution for treating wounds, preferably for liquid wound treatment of acute and chronic wounds, made of an aqueous solution including zinc, iron, and acid, wherein the per liter proportion of zinc is 10 to 100 mg, the proportion of iron is 6.5 to 60 mg, and the proportion of acid is selected such that the pH value of the treatment solution is 2.5 to 3.5.

Abstract: The invention relates to a medical hand-held measuring device for measuring the pH value and/or the temperature of wounds, including a housing (2) having at least one display (6) for displaying the particular measured value, operating elements, and a probe (10) provided at an end of the housing, the probe having a probe arrangement (9) for producing electrical measurement signals that correspond to the pH value to be measured and/or the temperature to be measured . The probe (3) is electrically and mechanically connected to the housing (2) in a removable manner by means of a probe-sided coupling section (10) and a housing-sided coupling section (11).
