Abstract: A stand-alone continuous cardiac Doppler or acoustic pulse monitoring patch provides visual and auditory signals that a pulse or heartbeat is detected or not detected in a human subject. The invention is a small patch with a peel-away adhesive surface that is applied to the skin of the subject, preferably near a large artery. For the Doppler monitor, the patch includes a pad formed of a conductive medium to enhance transmission and reception of ultrasonic waves. For the acoustic monitor, the pad has a sound focusing portion that permits entry of sounds and focuses the sounds toward a microphone, and the pad also has a sound insulating portion surround the sound focusing portion. The patch includes an integral power source. The Doppler patch has transmitters and receivers to send and detect reflected ultrasonic waves and a transducer to convert the reflected waves into an electrical signal.

The patch includes an integral power source, transmitters and receivers to send and detect reflected ultrasonic waves, a transducer to convert the reflected waves into an electrical signal, a processor to analyze the signal, a light to indicate the presence and strength of a pulse, and a speaker also to indicate the presence and strength of a pulse. The Doppler effect of waves reflecting from blood pumped from a heart is used to detect a pulse in the subject. The presence of a pulse is analyzed by the processor to determine the frequency and strength of blood flow.

Abstract: The present invention discloses a ring cutter and ring cracker intended for use by medical personnel. The ring cutter employs a tissue guard that slips under the ring to protect the patient's finger or other appendage. A clipper head is inserted into the tissue guard. The tissue guard does not move and prevents the jaws of the clipper from injuring the patient. The tissue guard may be constructed of plastic that will break away after use to prevent contamination between patients. The invention also incorporates a ring cracker for breaking tungsten or ceramic rings. A recess in a ring base in one of the arms of the ring clipper retains a part of a ring. In the other arm, a threaded bolt with a hardened tip extends toward the ring. The arms of the clipper can be locked by a bar in a fixed position. A knob on the bolt allows a hardened tip at the end of the bolt to exert pressure on the tungsten or ceramic ring until it cracks, without injury to the patient.
