Sep 29, 2015

Appl. No.:

14/868963

Inventors:

- Baltimore MD, US
Julie Campbell - Westerly RI, US
Elizabeth Hunt - Stevensville MD, US

International Classification:

G09B 5/06
G06F 3/16
G06F 3/14
H04N 5/225

Abstract:

An embodiment in accordance with the present invention is directed to an electronic training tool having one or more sensor components. The sensor components include a single depth camera and accelerometer or force sensor. The training tool also includes a software component for signal processing of sensor data and analysis of user performance. The user is given feedback based on quality of chest compressions, which is determined using data related to depth of compressions, rate of compressions, and recoil of compressions. Feedback is presented to the user and/or the trainer of the user via a user interface governed by a software program that can be run on a computing device such as a pc, laptop, tablet, smartphone, etc. The user interface imitates the user interface of a clinical monitor/defibrillator, specifically a defibrillator with a built-in QCPR feedback functionality.

US Classification:

12820222, 434265

Abstract:

A manual ventilation feedback sensor for use in clinical and training settings is disclosed. Namely, a manual resuscitator device is disclosed that comprises a bag valve mask, a one-way valve, a manual ventilation bag, and a sensing module, wherein the sensing module can comprise a pressure sensor and/or flow transducer. Sensing module may further comprise a controller for processing information from the pressure sensor and/or flow transducer; namely for determining and indicating a ventilation rate. Indicators are provided to guide the user with respect to a target or desired ventilation rate.

US Classification:

434265, 434262, 434267

Abstract:

The present invention is directed to systems for interfacing between sensors and sensor simulators and clinical monitors and devices. The present invention is used to incorporate sensors and sensor simulators into training and clinical demonstrations. A system in accordance with the present invention includes a hardware component configured to transmit an output signal associated with a typical clinical sensor such as sensors for end-tidal CO, pulse oximetry, temperature, blood pressure, near-infrared spectroscopy (NIRS) sensors, and CPR sensors to a clinical monitor or similar device. The system of the present invention also provides a software component to produce and transmit or to receive and make use of the simulated or actual sensor; the system also provides a hardware component to interface the software component to the clinical monitor, defibrillator, and/or sensor.

International Classification:

G09B 23/28

US Classification:

434262

Abstract:

The present invention takes the form of a device for training a user in defibrillation technique. The device includes a non-conductive belt that encircles a chest of a typical training simulator. The device includes conductive studs disposed in the AP or AL position, and therefore allows for training of the AP or AL defibrillation technique, respectively. The device can be used in conjunction with a high-technology simulator. In such a case the conductive studs redirect simulated cardiac rhythm signals and defibrillator electricity, allowing for the simulation of defibrillation in the AP position. The device can also be used in conjunction with a low-technology simulator or a pillow to provide AP and/or AL defibrillation functionality. In such a case, a rhythm simulator is used to simulate heart rhythm and dissipate defibrillation energy.
