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).

Disclosed is a chest compression device. The chest compression device includes a back for supporting the back of a patient, a compression part for compressing the chest of the patient, a U-shaped support for supporting the compression part, a pair of driving parts for allowing the support and the compression part connected thereto to perform a vertical reciprocating movement, and a control part for controlling the operation of the pair of driving parts.

A device for cardiopulmonary massage and/or resuscitation of a patient, which has a massage device arranged on a support board and includes a reversibly drivable massage stamp that can be positioned at a desired contact area on the thoracic cage of the patient for performing cardiopulmonary massage, and further includes a retention plate element which can be positioned on the thoracic cage of the patient at the desired contact area and which, by using at least three clamping elements engaging on its circumference, can be fixed, in particular can be connected to and braced by the support board. This has the effect that the mechanical cardiopulmonary massage can be maintained upright even during difficult transport maneuvers, since the relative position of the patient with respect to the massage device is not appreciably changed by its being clamped between the support board and the retention plate element.

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.

The present invention relates to a multi-part device for generating a clearly audible sound when an external force is applied onto a first force-transmission means that acts, via a spring system, on a base plate in an apparatus for controlled cardiopulmonary resuscitation of the human body in the event of cardiac arrest, and is characterised in that the external geometric dimensions and shapes are adapted to the anatomical conditions of the pectoral-adjacent thorax, in particular the spring system generating a signal that acts on at least one oscillatable element, the spring system being arranged between the first force-transmission means and the base plate, which spring system consists substantially of at least one spring element and one planar spring element, in particular the spring element also being a conical spring element.

A compression device may include a compression plunger in operable communication with a fulcrum assembly and housing assembly in operable communication with a stepper assembly. The compression device may be constructed and arranged to allow a user to administer CPR to a patient by stepping on a portion of the stepper assembly to generate hydraulic power that may be utilized to move the compressor plunger to apply compressive force to the patient's chest. The compression device may include a housing assembly and fulcrum assembly constructed and arranged to provide for variable height and width such that patients of varying sizes can be accommodated and may receive CPR.

The device according to the invention is used for a cardiopulmonary massaging and/or resuscitation of a patient and is provided with a massage stamp (17) which can be reversibly driven by a drive device in an actuation direction (18) and which has a pressure surface (31) that can be positioned at a contact region on the chest (12) of a patient (11). In order to ensure that the chest compressions are interrupted upon reaching a specified compression force, the massage stamp (17) has a stamp upper part (19) and a stamp lower part (20) which is operatively connected to the stamp upper part (19). The stamp upper part (19) and the stamp lower part (20) can be adjusted relative to each other in the actuation direction (18) at least between a first position which defines a working length (L) and a second position in which an effective length (1) of the massage stamp (17) is shortened compared to the working length (L). In the first position, the stamp upper part (19) is locked with the stamp lower part (20) by means of a releasable locking mechanism (21) and the locking mechanism (21) is released upon reaching or exceeding a specified compression force transmitted by the massage stamp (17).

A defibrillation system may include a cardiac arrest detector detecting whether cardiac arrest of a passenger has occurred in a state of taking a seat of a self-driving vehicle and fastening a seatbelt of the vehicle; a passenger posture detection device detecting a posture of the passenger; a seat driving device changing the posture of the passenger into another posture in which the passenger lies down based on a detection signal of the passenger posture detection device when the cardiac arrest of the passenger occurs; a heart position detector configured to search for a position of a heart of the passenger; a defibrillation robot to perform a CPR method or a method using an AED on the heart of the passenger; and a controller controlling operation of the seat driving device, the heart position detector, and the defibrillation robot based on detection signals of the cardiac arrest detector and the passenger posture detection device.
