  • Patent number: 10123764
    Abstract: In various embodiments, vibro-acoustic transducer arrangements in accordance herewith are optimized for sensing and transducing acoustic phenomena occurring within a patient's body, and manifesting themselves at the skin surface with frequencies ranging from 0.001 Hz to 10 kHz. Strategies for effectively coupling to the skin include judicious mismatching of mechanical impedance, the use of impedance-matching gels or liquids, a shaped (e.g., domed) pickup, material selection, and/or a peripheral leaf-spring arrangement permitting relative movement between inner and peripheral diaphragm portions. The spring stiffness or spring compliance of the leaf springs may be selectively chosen to optimize the frequency response of the sensor.

    Abstract: An ear piece assembly (10, 100, 200, 300, 500, 600, 700, 800, 900, 1000) designed for a stethoscope or other headpiece, and configured to allow rotation of an ear tip (20, 120, 220, 320, 420, 520, 620) of the assembly about a central axis (relative to the rest of the assembly) and to allow limited off axis movement of the ear tip (relative to the rest of the assembly). In typical embodiments, the ear piece assembly is designed to fit a user's ear canal and stay in place during typical use without rotational or off axis movement of the ear tip relative to the ear canal, and to provide substantially more comfort to the user than would a headpiece with a conventional ear tip assembly, particularly for prolonged wearing by the user. Other aspects of the invention are a headpiece (e.g.

  • Patent number: 8447043
    Abstract: A stethoscope chest piece has a chest piece housing containing a piezoelectric (piezo) element mounted within a housing. The piezo element converts body signals to an electrical representation that is processed by circuitry on a circuit board. A back stop is affixed to the circuit board to prevent excess excursion by the piezo element and may be one of the circuit elements on the circuit board. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Patent number: 8396228
    Abstract: An active stethoscope or other sound detection device, including a diaphragm, at least one floating mass mounted to the diaphragm (at at least one coupling point of the diaphragm), and an acoustic transducer mounted to the floating mass. Preferably, each floating mass is configured and mounted so that as each floating mass and each coupling point of the diaphragm move in sympathy with acoustic waves (to be detected) that impinge on the diaphragm, the acoustic transducer rides with and is stabilized by the floating mass to which it is mounted and the diaphragm is stabilized by each floating mass. The acoustic transducer can be of any of many different types. For example, it can be a microphone, or an optical, capacitive, or inductive transducer. The diaphragm can have an isolating portion which absorbs acoustic surface wave energy incident thereon, or otherwise prevents or reduces transmission of acoustic surface waves through the isolating portion between regions of the diaphragm.

  • Patent number: 8387745
    Abstract: A cover for a stethoscope to prevent microbes from transferring from a patient to a stethoscope is disclosed. In one embodiment, a stethoscope cover comprises an antimicrobial barrier having a first and second surface, image forming material disposed on the antimicrobial barrier first surface, and an adhesive layer disposed on the second surface of the antimicrobial barrier to attach the antimicrobial barrier to a stethoscope. In some embodiments, the image forming material is configured to depict an image of a product. In some embodiments, the image forming material is configured to depict an image of an animal or character, to evoke feelings of happiness in a young patient.

  • Patent number: 8333718
    Abstract: A sensor for sensing bioacoustic energy includes a housing comprising an interfacing portion configured to establish coupling with a body part during use. The sensor includes a transducer element coupled to the interfacing portion of the housing and configured to sense sounds produced by matter of biological origin. One or more conductors are coupled to the transducer element. A mass element is compliantly coupled to a surface of the transducer element. Intervening material is disposed between the transducer element surface and the mass element, and allows for differential motion between the transducer element surface and the mass element during excitation of the transducer element.

  • Patent number: 8307942
    Abstract: A flat earplug and flat earplug package assembly is provided and a method of forming a flat earplug. The flat earplug includes a flat, rectangular foam sheet having a first surface and second surface, and adapted to be rolled up upon itself to form a coiled earplug for insertion into a user's ear. An inner coil is compressed to form a rigid coil when rolled up upon itself and an outer coil expands after the coiled earplug is inserted into the user's ear. The flat earplug package assembly includes a tray container for retaining the foam sheet therein and a wrapping for enclosing the flat earplug and tray container therein.

  • Patent number: 8275140
    Abstract: A transducer system is disclosed for detecting actual or simulated body sounds. An audio signal generation and detection system is disclosed for the purposes of simulating the medical examination of a patient or simulating the listening of sounds seeming to emanate from a live or inanimate body. A signal generator sets up a voltage potential at an electrode physically attached to the body, or electrically connected to a body, thereby setting up a voltage potential on a surface area of the body. An electric field potential sensor or a capacitive electrical sensor placed in proximity to the electrode or body surface then detects the voltage potential. The signals produced by the signal generator can represent heart, lung, bowel or other sounds and the electrical sensor can take the physical form of a listening device such as a stethoscope, thereby creating a simulation of listening to body sounds for medical diagnostic purposes.
