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.

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.

A defibrillator (30) with an automatic self-test system (42) that includes a test signal generator and a defibrillator status indicator. The test system (42) preferably performs functional tests and calibration verification tests automatically in response to test signals generated periodically and/or in response to predetermined conditions or events and indicates the test results visually and audibly. The invention also relates to a method for automatically determining and indicating a defibrillator's status without human intervention.
摘要:
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.
摘要:
An ECG monitoring system for ambulatory patients includes a small multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. The processor also analyzes the received ECG signals for predefined arrhythmia. If an arrhythmia is detected, a wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a cellphone handset. The cellphone handset automatically relays the event information and ECG strip to a monitoring center for further diagnosis and necessary intervention.
摘要:
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.
摘要:
A system and method for synchronizing delivery of shock therapy to a patient from a defibrillator. The period for a patient ECG waveform exhibiting a threshold periodicity is calculated and a time reference during the period of the ECG waveform is determined for delivery of shock therapy to the patient. The defibrillator is prepared for delivery of the shock therapy at the time reference during a subsequent period of the ECG waveform.
摘要:
Handling or removal of a pair of pre-connected defibrillator electrode pads from their package, or a compartment in the defibrillator, is detected in order to effectively time the issuance of prompts to guide the user. Detection occurs when an impedance level between the electrode pads varies sufficiently over time to indicate occurrence of the handling or removal event. The pads are preferably configured to leverage variability in the impedance that results from bending of pads during handling or removal.
