| 20080312524 | Medical Sensor Having Electrodes and a Motion Sensor - A medical sensor having at least one electrode configured to be placed on a patient for medical monitoring and a motion sensor integrated in the medical sensor with the electrode, the motion sensor configured to detect patient motion and provide electrical signals in response thereto. | 12-18-2008 |
| 20090105602 | Staged life-threatening arrhythmia detection algorithm for minimizing power consumption - A two-stage digital algorithm uses a highly sensitive low power digital first stage to detect one or more alarm conditions, and one or more complex digital subsequent stages that identify the detected alarm condition with more specificity. The one or more complex digital subsequent stages are not activated, and consume no power, until an alarm condition is sensed by the low power consumption digital first stage. Given that the second stage will process the data more rigorously, the low power first stage can be set to be more sensitive and generate what would otherwise be excessive alarms, which are ultimately filtered out by the subsequent stages. By staging the digital analysis algorithms, the present invention achieves high sensitivity for alarm conditions with low computational throughput and low power consumption, and achieves high specificity with more computationally intensive algorithms that only run occasionally. | 04-23-2009 |
| 20100198044 | SHIELDED BIOMEDICAL ELECTRODE PATCH - A biomedical electrode patch having improved resistance to capacitive coupling to extraneous electric fields. The patch includes a conductive shield and a contact portion formed on an upper surface thereof. The contact portion extends through the film layer and contacts an electrode formed of a material suitable for conducting electrical signals from a patient. Conductive traces formed on the lower surface of the tab extend to contact pads. A nonconductive layer is printed over the traces and can have a shield formed thereon. | 08-05-2010 |

| 20080288011 | Method and Article for Storing an Automatic External Defibrillator for Use Without a Prescription - A method and article for storing an automatic external defibrillator for use without a prescription are described. The hermetically sealed electrode pads of the OTC AED are electrically coupled to the OTC AED base unit where they are constantly accessible to self-test circuitry inside the base unit for periodic, automatic self-test. In one embodiment the self-test is designed to determine whether the conductive gel of the electrode pads has dried out. In another embodiment self-test circuitry also tests the battery while the OTC AED is being stored prior to use. | 11-20-2008 |
| 20100076510 | AED HAVING CPR PERIOD WITH PAUSE FOR ECG ACQUISITION - A defibrillator is described which executes a resuscitation protocol having a CPR pause period. The CPR pause period may be interrupted for the acquisition of ECG signal data which is not contaminated by chest compression artifacts. Following the acquisition of ECG signal data, the CPR period resumes and continues for its full period. The ECG signal data acquired during the interruption of the CPR period is analyzed and, if a shockable rhythm is identified, a shock sequence is initiated immediately upon conclusion of the CPR period. | 03-25-2010 |
| 20100081913 | HANDHELD, REPOSITIONABLE ECG DETECTOR - An ECG monitoring device comprises an integral handheld device including a ECG electronic module and an electrode patch having a plurality of electrodes which contact a subject by conductive hydrogel. A release liner covers and protects the hydrogel prior to use and is removed to expose the hydrogel. A second release liner is removed to expose a pressure sensitive adhesive by means of which the device is attached to a subject. The first and second release liners may be parts of a single release liner layer. After use the electrode patch is disposable and the ECG electronic module is detached from the patch for reuse. | 04-01-2010 |
