Legal Notice
This page is intended to serve as notice under 35 U.S.C. § 287(a). The DPNCheck device and DPNCheck biosensor are covered by the following U.S. patents: U.S. Pat. Nos. 9,014,798; 9,173,581; 10,004,445; 10,881,311.
Automated Stimulus Artifact Removal for Nerve Conduction Studies
A method for the automated removal of a stimulus artifact from an electrophysiological signal waveform. The novel method comprises providing a model of the stimulus artifact that is physically derived and based on known properties of the electrophysiological signal waveform acquisition hardware and stimulator, and filtering the stimulus artifact out of the electrophysiological signal waveform using the model.
Apparatus and Method for the Automated Measurement of Sural Nerve Conduction Velocity and Amplitude
Apparatus for measuring sural nerve conduction velocity and amplitude, including a housing, stimulation means for electrically stimulating a human sural nerve, a biosensor comprising electrodes for detecting sural nerve responses, and processing means for calculating conduction velocity and amplitude. The device is designed to be placed on a patient's anatomy in the vicinity of a sural nerve.
Apparatus and Method for Stimulator On-Skin Short Detection
The invention relates to apparatus and methods for stimulating living tissues to determine nerve conduction properties. The invention overcomes the problem of reporting potentially inaccurate nerve conduction results by detecting a stimulator probe short or shunt condition during nerve conduction tests, accomplished by monitoring the magnitude of stimulus artifact waveform and voltage difference between stimulator probes.
Apparatus and Method for the Automated Measurement of Sural Nerve Conduction Velocity and Amplitude
A continuation patent for apparatus measuring sural nerve conduction velocity and amplitude. The apparatus includes a housing, stimulation means for electrically stimulating a human sural nerve, a biosensor comprising electrodes for detecting sural nerve responses, and processing means for calculating conduction velocity and amplitude. The device provides automated measurement capabilities for diabetic peripheral neuropathy testing.
