A chest compression device includes a piston to apply compression to the sternum and incorporates leaf springs simultaneously driven by the piston to apply lateral compression to the thorax during chest compressions. A motor in the chest compression device provides motive power to cyclically extend and contract the piston to provide therapeutic chest compressions. One end of each leaf spring is operably connected to the piston and the other end of each leaf spring is secured to the backboard/base or to a support leg of the chest compression device such that during extension of the piston, each leaf spring is compressed against the device base or leg which causes the springs to flex and provide lateral compression of the patient's thorax in addition to the sternal compression of the piston.

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. The system includes an applicator device configured to provide ACD CPR treatment to a patient's chest according to a plurality of phases at least one sensor configured to be coupled to the patient's chest and to measure at least one parameter related to the ACD CPR treatment and information for determining whether at least one transition point of the ACD CPR treatment has been reached; and one or more processors configured to provide a feedback signal based on a parameter for administering ACD CPR treatment to the patient's chest according to a desired treatment protocol.

A method for cardiopulmonary resuscitation (CPR) includes supplying an inflation gas at an operative pressure to an inflation actuated soft gripper device to change form from an undeployed state to a deployed grip state that accommodates and grips a human torso. The inflation actuated soft gripper device includes a first inflatable gripper arm having a first distal end and a second inflatable gripper arm having a second distal end. The first distal end and the second distal end approach one another from the undeployed state to the deployed grip state. The first and second distal ends are spaced apart from one another further in the undeployed state than in the deployed grip state. An actuator power and a CPR control signal are delivered to a CPR pressure application device to cyclically extend and retract a pressure applicator along an axis in alignment with a sternum of the human torso.

An automated cardiac massage device has two dynamic, multilayered compressive units oriented to compress the heart using an outer, non-compliant layer which supports an inner layer made of expandable and compressive material configured to contract and expand to facilitate cardiac filling and ejection. The compressive units are attached to a flexible apex member which modulates the shape and position of the two compressive units to provide maximal apposition to the heart while the device remains in use. Barometric pressure sensors may be incorporated on the inner layer of the compressive unit to measure the systolic and filling diastolic pressure within the heart. A third, detachable, phalange arises from the flexible apex member to provide a third station of support for the heart should the configuration of the compressive units require an additional point of support to secure the heart within the apparatus.

Various embodiments of systems, devices, components, and methods for providing external therapeutic vibration stimulation to a patient are disclosed and described. Therapeutic vibration stimulation is provided to at least one location on or adjacent to a patient's skin (such as through clothing or a layer disposed next to the patient's skin), and is configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient. Inducing such resonance can aid in training autonomic reflexes and improve their functioning.

A portable medical triage kit and interactive application that leads a user through a medically acceptable triage protocol for treating medical emergencies. The interactive application leads the user to treat major life threats of all nearby victims before treating minor threats of anyone.

A system for assisting a rescuer with treatment of a patient is described. An example system includes a mobile computing device that includes a user interface and a processor coupled to memory. The processor is configured to cause the user interface to prompt the rescuer to select a proficiency level from among multiple proficiency levels including a basic proficiency level and at least one non-basic proficiency level. The basic proficiency level includes basic resuscitation instructions for the rescuer. The system is further configured to receive an input from the rescuer of the selected proficiency level. The system provides, if the rescuer selects the basic proficiency level, the basic resuscitation instructions to the rescuer, and provides, if the rescuer selects the at least one non-basic proficiency level, non-basic instructions to the rescuer. The system transmits signals to control a defibrillator according to the selected proficiency level.

The invention disclosed here relates in general to the field of medical devices. In particular, to devices and methods for improving the clinical outcome of patients suffering from cardiac dysrhythmias without cardiac arrest. This method and/or device integrates mechanical, pneumatic, acoustic and/or electrophysiologic capabilities with electrical countershock or pacing capabilities such that the probability of successful cardioversion or pacing is increased. The sequence, forces, and electrical properties of the subsystems can be computer controlled and adjusted in response to biomarker inputs.

A system and method for integrating and synchronizing an automated mechanical cardiopulmonary resuscitation (CPR) device with components of cardiac catheterization laboratories so as to enhance the efficacy of each intervention. Synchronization can include image gating so that a monitor shows real time images during relaxation of the CPR, and a static image during compression of the CPR.

A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16).
