A portable early warning device for use in detection of breaches in protective garments such as gloves, during surgical procedures and the like. The device embodies a central process and source unit containing sensing wave generator, indicators, driving circuitry, digital analyzing and monitoring circuitry and a power source. The central process and source unit is separately directly connected to the object, e.g. skin of the patient, and to the device carrier, e.g. skin of the surgeon, via standard wires and EKG type terminal connectors. A conductive breach of protective garments such as surgical gloves with in vivo patient fluids, such as blood (of a possibly hazardous nature), completes a circuit and triggers a warning (either visible, audible, or mechanical) of the breach. The driving and monitoring circuitry, which generates a pulse specific current, prevents spurious signals despite the heightened sensitivity required by the device for triggering and the presence of numerous electronic devices, with emitting electrical discharges, which are present in operating rooms. The device is provided with self diagnostic monitoring means to ensure proper over-all hook-up; separate proper connection to each of the surgeon and patient; sufficient battery power; and proper operation.

An early warning portable, battery powered device for use in detection of a breach in at least one protective barrier between an object and at least one carrier, during surgical and health care procedures, wherein the device contains a battery power source and is separately electrically connected, with individual connections, to the object and at least one carrier by dual electrode cables, said device comprising central processing means having discrimination means, connection integrity alarm means, breach alarm means, and means to constantly monitor integrity of each connection during use of the device, with said connection integrity alarm means, said breach alarm means, and said means to constantly monitor integrity of each connection, each being electrically connected to said central processing means, wherein any failed connection condition causes the connection integrity alarm means to generate an alarm as to such condition to enable the failed connection condition to be corrected, and wherein, with a breach in said protective barrier, and establishment of a conductive connection between the object and said at least one carrier, a circuit is completed through the breach with a current generation from said battery power source, and a warning alarm is triggered by the breach alarm means; said discrimination means, being electrically connected to said breach alarm means and said current generation, wherein said warning alarm is only triggered when the discrimination means determines that the generated current is of a specific predetermined type, wherein said device further comprises electrical pulse generation means whereby electrical pulses, continually generated by the electrical pulse generation means, are separately directed to the object and the at least one carrier respectively, to monitor integrity of each connection during use of the device, wherein the electrical pulses, separately directed to the object and the at least one carrier respectively, differ such that they provide said generated current of specific predetermined type, identifiable by said discrimination means.
