20130197324 | METHOD AND SYSTEM TO MONITOR, DETECT, DIAGNOSE AND PREDICT THE SEPARATION/RUPTURE OF THE UTERINE SCAR ASSOCIATED WITH VAGINAL BIRTH AFTER CESAREAN PROCEDURES - A system and method of acquiring and transmitting uterine EMG signals is disclosed, where a signal processing module processes incoming uterine EMG signals from a patient and wirelessly transmits a processed signal to an information relaying device. The information relaying device is then configured to download the processed signal and transmit the signal to a call center or health care facility for physician evaluation. The system is ambulatory, thus allowing the patient to record and transmit uterine EMG signals anywhere a satisfactory transmission may be made. Additionally, a system and method of using electromyography for monitoring and diagnosis of uterine rupturing is disclosed, where incoming electrical signals from the lower uterine segment muscle fibers demonstrate an attenuated signal as the lower uterine segment thins and separates during the dilatation and effacement process of labor identifying those patients at increased risk for rupture. | 08-01-2013 |
20110270118 | MEASURING AND DISPLAYING THE PROPAGATION VELOCITY OF UTERINE ACTION POTENTIALS TO DETERMINE THE ONSET OF LABOR - A method and system to examine and measure the propagation velocity of electrical activity in pregnant patients, labor and non-labor patients at term and preterm, and non-pregnant patients, thereby providing valuable information regarding the state of a patient's uterus. The method can include obtaining uterine EMG signals from a series electrodes, processing the raw uterine EMG signal in a signal processing module and assessing the temporal interval between adjacent electrodes. The propagation velocity can then be estimated by averaging the time required for the uterine EMG signal to traverse a distance between adjacent electrodes. | 11-03-2011 |
20080275316 | SKIN IMPEDANCE MATCHING SYSTEM AND METHOD FOR SKIN/ELECTRODE INTERFACE - The present invention relates to a system for measuring the input impedance of a skin/electrode interface and selectively modifying the input impedance of the monitoring circuit to match the measured input impedance. More particularly, a simplified method for correcting for input impedance mismatch between electronic monitoring circuitry and the skin/electrode interface. In accordance with one embodiment of the invention, an input impedance measuring circuit will interface with a microprocessor and a reconfigurable switch network to select the input impedance of the electronic monitoring circuitry, thus eliminating the impedance sensitivity of EMG or EKG instruments. | 11-06-2008 |
