A medical monitor is provided. The medical monitor may include a transparent display sheet providing spaced apart first and second conductive elements along a distal side of the display sheet. Electric ink marks may electrically connect to either the first or the second conductive element so as to form an open circuit having spaced apart first and second electric ink markings along said distal side. The display sheet may be sandwiched between two bandage sheets prior to placing the proximal side near or around a wound site the open circuit was tailored for. Wherein blood from the wound site would migrate through the two bandage sheets onto the distal side, bridging the open circuit of adjacent first and second ink markings, so that if the open circuit where electrically connected in series with a power supply and an alarm, the alarm would be powered.
