Abstract: A portable diagnostic instrument for use by medical professionals. The portable diagnostic instrument can comprise a control unit that can maintain the frequency of sound or vibration produced by the device constant, even when battery power is reduced. The control unit can also comprise a warning unit to provide information about remaining battery life to the user. Furthermore, the portable diagnostic instrument can comprise a unit capable of producing vibration and a unit capable of producing sound at differing frequencies. The device can produce both the sound and vibration at the same time or each can be operated individually. Moreover, the device is capable of being attached to other medical equipment that is carried by a medical professional or can be easily kept in a pocket, so that it is readily available when needed.

Abstract: A portable diagnostic instrument for use by medical professionals. The portable diagnostic instrument can comprise a circuit control that can maintain the output of the light intensity constant, even when battery power is reduced. The circuit control system can also comprise a warning system to provide information about remaining battery life to the user. Furthermore, the portable diagnostic instrument can comprise an otoscope further comprising a separate, folding magnifying lens assembly and a separate, folding specula assembly.

Abstract: The present otoscope attachment, when used with a cellular phone comprising a light source, provides a powerful otoscope that is both lightweight and portable. This otoscope is powered by one or more light sources comprising the cellular phone, which provides the light necessary to conduct a medical examination with the otoscope. A further feature of this device is its ability to be folded flat making it easy to carry in one's pocket.

Abstract: A combined diagnostic device for use by medical professionals, which can function as both a stethoscope and a reflex hammer. The combined diagnostic device can function as a stethoscope and a reflex hammer. The diaphragm housing of the stethoscope can be modified so as to act as the head of the reflex hammer and a telescoping handle can connect to and be extend from the diaphragm housing. This design would allow for two instruments to be available to the medical professional without the inconvenience of needing to carry two instruments. The combined diagnostic device would have approximately the same mass and dimensions as a typical stethoscope allowing it to be stored and transported as if it were a typical stethoscope.
