Abstract
A monitor for detecting external bleeding from a puncture site on a patient. The monitor is provided with a self-sticking bandage portion on one end connected by means of a flexible connecting strip to a self-sticking holder portion on an opposite end. The bandage portion is applied so the puncture site is visible through a transparent window provided over a central opening in the bandage portion. A pair of spaced apart wires encircles the central opening, extends across the connecting strip and removably secures to a portable alarm device containing a battery and alarm connected in series by means of the wires. When the puncture site hemorrhages, blood contacts the wires, allowing electrical current to flow between the wires via the electrically conductive blood and thus supplying electricity to the alarm in order to activate it.
