Patents by Inventor Richard J. Enroth

Richard J. Enroth has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7058438
    Abstract: A portable apparatus which allows a user to perform self-diagnostic evaluation of nerve sensory latency between a pair of epidermal locations proximal to nerve conduction paths. The device provides a simple and low-cost self-diagnostic apparatus which may be used for the detection and ongoing monitoring of sensory latency, such as sensory latency which is the result of carpal tunnel syndrome. The apparatus is powered by a single battery which provides power to all circuitry of the apparatus. Upon power activation, the device generates a series of high voltage stimulus pulses at an electrode in epidermal contact with the user/operator. The nerve response voltage is detected by a second electrode located along nerve pathway and the time delay between stimulus and response is displayed and periodically updated as each new response is detected.
