August 20, 2014



By a News Reporter-Staff News Editor at Biotech Week -- A patent by the inventors Khuon, Pisit (Johnston, RI); Totman, Mark (Winchester, MA), filed on March 4, 2013, was published online on August 5, 2014, according to news reporting originating from Alexandria, Virginia, by NewsRx correspondents (see also Medical Device Companies).

Patent number 8798743 is assigned to ZOLL Medical Corporation (Chelmsford, MA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "Sudden health problems such as sudden cardiac arrest and injuries caused by accidents kill thousands of people and cause permanent injury every year. Fast and competent care to resuscitate such victims of these problems can be essential to positive outcomes in such situations. For example, it is said that the chance of surviving a sudden cardiac arrest falls by ten percent for every minute of delay in providing effective treatment.

"Resuscitation treatments for patients suffering from cardiac arrest generally include clearing and opening the patient's airway, providing rescue breathing for the patient, and applying chest compressions to provide blood flow to the victim's heart, brain, and other vital organs. If the patient has a shockable heart rhythm (ventricular fibrillation or pulseless ventricular tachycardia), resuscitation also may include defibrillation therapy. Along with such action, an electrocardiogram (ECG) signal for the patient may be electronically captured, displayed, and monitored, so that rescuers can determine when the patient's heart has returned to normal or near-normal operation, and determine when the heart exhibits a shockable rhythm."

In addition to the background information obtained for this patent, NewsRx journalists also obtained the inventors' summary information for this patent: "A self-contained response unit for use by a caregiver providing resuscitation to a victim of cardiac arrest includes one or more defibrillator electrode pads and one or more sensors contained within a compartment of the response unit. The electrode pads can be removed from the compartment of the response unit and positioned on the chest of the victim such that a defibrillator can provide defibrillation to the victim through the pads. The sensors are integrated into a bottom side of the response unit and sense physical movement, such as the movement of chest compressions being applied to the victim when the caregiver delivers cardiopulmonary resuscitation (CPR) to the victim. The containment of both defibrillator electrode pads and sensors in a single unit helps the caregiver to provide treatment to the victim more efficiently.

"In a general aspect, an apparatus includes a housing comprising a first side and a second side; a chest compression sensor coupled with the second side of the housing; at least one compartment partially formed by one of the first side and the second side of the housing; and at least one removable defibrillator electrode pad contained in the at least one compartment partially formed by one of the first side and the second side of the housing.

"Embodiments may include one or more of the following.

"The apparatus includes a dispenser disposed in the at least one compartment and configured to facilitate removal of the at least one removable defibrillator electrode pad. In some cases, the at least one removable defibrillator electrode pad is arranged on the dispenser. In some cases, the dispenser is a roller. In some cases, the dispenser is coated with a release liner.

"At least a portion of the at least one removable defibrillator electrode pad is rolled around a roller disposed between the first side and the second side of the housing. In some cases, the at least one removable defibrillator electrode pad is configured to be unrolled during removal of the removable defibrillator electrode pad from between the first side and the second side of the housing.

"The apparatus includes two removable defibrillator electrode pads configured to be placed on a chest of a victim of cardiac arrest, the removable defibrillator electrode pads for use with a defibrillator. In some cases, each removable defibrillator electrode pad is arranged on a corresponding dispenser disposed between the first side and the second side of the housing.

"The chest compression sensor includes a motion detection device, such as an accelerometer.

"The apparatus includes a cover configured to enclose the at least one removable defibrillator electrode pad within the compartment partially formed by one of the first side and the second side of the housing. In some cases, the cover is at least one of airtight and watertight. In some cases, the cover includes a hermetic seal disposed at least around the sides of the housing. In some cases, the cover is configured to enclose the housing.

"The housing is configured to be placed on a chest of a victim of cardiac arrest such that the chest compression sensor can measure parameters associated with chest compressions applied to the victim.

"The apparatus includes a cable in electrical communication with the chest compression sensor and configured to be connected to a defibrillator.

"The apparatus includes a cable port in electrical communication with the chest compression sensor and configured to receive a cable connected to a defibrillator.

"In a general aspect, a method includes providing a housing comprising a first side and a second side. A chest compression sensor is coupled with the second side of the housing. The method includes removing at least one removable defibrillator electrode pad from a compartment partially formed by one of the first side and the second side of the housing.

"Embodiments may include one or more of the following.

"Removing the at least one removable defibrillator electrode pad includes removing the at least one removable defibrillator electrode pad from a dispenser disposed in the compartment.

"Removing the at least one removable defibrillator electrode pad includes removing the at least one removable defibrillator electrode pad from a roller disposed in the compartment. In some cases, removing the at least one removable defibrillator electrode pad includes unrolling the at least one removable defibrillator electrode pad.

"The method includes opening a cover enclosing the at least one removable defibrillator electrode pad within the compartment.

"The method includes positioning the housing on a chest of a victim of cardiac arrest.

"The method includes positioning the at least one removable defibrillator electrode pad on a chest of a cardiac arrest victim.

"The method includes removing two removable defibrillator electrode pads from corresponding compartments. In some cases, the method includes positioning the two removable defibrillator electrode pads on a chest of a cardiac arrest victim. In some cases, the method includes electrically connecting each of the two removable defibrillator electrode pads with a component of a defibrillator.

"The method includes electrically connecting the chest compression sensor to a defibrillator.

"In a general aspect, an apparatus includes a housing comprising a first side and a second side; a chest compression sensor coupled with the second side of the housing; a compartment partially formed by one of the first side and the second side of the housing; at least two rollers disposed in the compartment, the at least two rollers coated with a release liner; and at least two removable defibrillator electrode pads, each removable defibrillator pad arranged on a corresponding one or more of the two rollers.

"Embodiments may include one or more of the following.

"The at least two removable defibrillator electrode pads are configured to be unrolled during removal of the removable defibrillator electrode pads from between the first side and the second side of the housing.

"The chest compression sensor comprises an accelerometer.

"The apparatus includes a cover configured to enclose the at least two removable defibrillator electrode pads within the compartment partially formed by one of the first side and the second side of the housing.

"The housing is configured to be placed on a chest of a victim of cardiac arrest such that the chest compression sensor can measure parameters associated with chest compressions applied to the victim.

"The self-contained response unit described herein may have one or more of the following advantages. Containment of both defibrillator electrode pads and sensors in a single unit helps the caregiver to provide treatment to the victim more efficiently, improving treatment outcomes. Handling of the defibrillator electrode pads by the caregiver is reduced, thus contributing to improved performance of the electrode pads and enabling the caregiver to deploy the electrode pads efficiently. The deployment of the self-contained response unit is straightforward and layered visual cues on the components of the response unit help the caregiver to understand the operation of the response unit.

"Other features and advantages are apparent from the following description and from the claims."
