Abstract: Methods and apparatus for anchoring a catheter to a patient's skin using a catheter anchoring device are described. The catheter anchoring device includes one or more pairs of sharps with a sharpened end configured to pierce the surface of the skin. A locking mechanism for the sharps is used as a failsafe mechanism. The catheter anchoring device further includes a catheter clamp for securing a catheter to the catheter anchoring device. Releasing the clamp allows an operator to reposition and secure the catheter at the new position without moving the catheter anchoring device.

Abstract: A template sheet is provided for use in the application of a medical grade adhesive to the skin of a user. In one preferred embodiment, the template is fabricated of a flexible plastic material having one or more openings in the sheet and marker openings are provided about the periphery of the one or more openings and through which the skin can be marked with a marking implement. By use of such markers on the skin, the template can be removed after placing the markings on the skin so that adhesive can be applied to the skin within the marked area without need for the template to remain in place during adhesive application. Alternatively, the template may be employed as a mask and the skin adhesive may be applied to the skin while the template is appropriately positioned on the skin of the user.

Abstract: An electronic stethoscope having several modes of operation to process acoustic signals to provide filtered signals useful for diagnosis. In one mode of operation the stethoscope substantially provides only acoustic signals generated by biological activity of the heart. In another mode of operation, the acoustic stethoscope substantially provides only acoustic signals generated by biological activity of the lungs. In another mode of operation, the electronic stethoscope disproportionately amplifies abnormal heart sounds and normal heart sounds to enhance diagnosis of heart abnormalities. The electronic stethoscope is operated in a manner similar to a conventional acoustic stethoscope and has similar spectral characteristics, thus allowing a user with acoustic stethoscope experience to easily use the electronic stethoscope.

Abstract: An apparatus and method for transmitting a signal having a first bandwidth through a telephone line having a second bandwidth, wherein the first bandwidth includes frequencies outside the second bandwidth is disclosed. The invention also provides a method and apparatus for demodulating the transmitted signal. The system also includes a mobile unit coupled to an electronic stethoscope that communicates with a base unit using a wireless communication link. In combination with the method and apparatus for transmitting signal through a conventional telephone line, the invention allows data representative of heart and lung sounds from an electronic stethoscope that is outside the passband of a conventional telephone line to be transmitted through the telephone system for remote diagnosis and analysis.
