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.

Catheter anchoring device and method

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.
