Abstract

A method and apparatus is provided, employing a wound meter, for assessing the progress of healing of a wound. A wound is washed with water (or any appropriate solvent), left moist for a predetermined time set by a timer (7) for analytes (in this case, lactate and glucose) to equilibriate with extracellular fluid. The wound meter also permits use of endogenous wound fluid in moist wounds. A dipstick is then applied to the extracellular fluid. The dipstick has active regions (1, 2 )each sensitive to just a respective one of the analytes. The dipstick is inserted into a sheath which individually exposes active regions. The sheath is inserted 11 into the wound meter and the concentrations of the analytes measured and calculated. The ratio between the concentrations of the analytes is calculated and displayed as a result. The dipstick is of known dimensions and the wound meter also comprises a colour camera so that a photograph of the wound can be taken with the dipstick adjacent the wound. The wound meter comprises a memory for storing patient data, all results, the coloured photograph and wound healing time algorithms, the memory being removable and/or down-loadable to a allow retention and/or provision to a central facility. Data can also be up-loaded to the memory. For accurate calculation after sampling and measurement, the wound meter also employs access to algorithms permitting output of predicted 'time to healing'.
