Abstract: The disclosed mechanical cardio-pulmonary resuscitation (CPR) apparatuses, systems, and devices have a plunger and a plunger displace sensor that can sense plunger displacement information during reciprocating cycles of the plunger. The disclosure CPR apparatuses, systems, and devices also have a microprocessor unit that can receive sensed plunger displacement information from the sensor and generate plunger driving instructions based on the plunger displacement information. The plunger driving instructions have one or both of a plunger driving force and a plunger amplitude for the reciprocating cycles.

Abstract: An alignment device for assisting a rescuer for correctly aligning a mechanical cardiopulmonary resuscitation (CPR) device. The alignment device can guide positioning of the backboard so that the backboard is correctly positioned prior to connecting an upper portion of the mechanical CPR device to the backboard. The alignment device can also include positioning the mechanical CPR device without a backboard or positioning the backboard and the upper portion of the mechanical CPR device nearly simultaneously.

Abstract: 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.

Abstract: A CPR machine (100) is configured to perform compressions on a patient's (182) chest that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A compression force may be sensed, and the driving is adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.

Abstract: A cardiopulmonary resuscitation (CPR) chest compression device, including a chest compression component structured to deliver chest compressions to a patient, and a controller electrically coupled to the chest compression component. The controller operates the chest compression component to switch between operating at least in a first mode for a first time period and a second mode for a second time period. The first mode includes compressing a chest of a patient at a first rate of compressions, at a first depth for each compression, and a first duty cycle, and the second mode includes compressing a chest of a patient at a second rate of compressions, at a second depth for each compression, and a second duty cycle, at least one of the second rate, the second depth, and the second duty cycle is different from the first rate, the first depth, and the first duty cycle.

Abstract: Techniques and devices for securing a medical device to a patient-carrying device, such as a mechanical CPR device to a stretcher, are described herein. In one aspect, a medical device stabilization strap may include a first removable attachment shackle connected to a first end of a first strap. An adjustable quick release buckle may be disposed between a second end of the first strap and a proximal end of a second strap. A second removable attachment shackle may be connected to a distal end of the second strap. The first and second removable attachment shackles may each include a U-shaped bracket for removably engaging a medical device. The adjustable quick release buckle may adjust a length of the second strap, for example, to secure the medical device to the patient-carrying device.

Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest.

Abstract: A CPR apparatus includes a chest compression unit and a means for mounting the chest compression unit on a patient. The chest compression unit includes a plunger disposed in a housing. At its one end extending from the housing the plunger has a compression member. The plunger is driven in a reciprocating manner by a reversible electromotor via a mechanism for translating rotational motion to linear motion or by a linear induction electromotor. The chest compression unit includes an electromotor control unit including a microprocessor, a first monitor for monitoring the position of the plunger in respect of the housing and a second monitor for monitoring the position of the plunger in respect of the mechanism for translating rotational motion to linear motion or the rotor of the linear induction electromotor. The monitored positions are communicated to the electromotor control unit. Also disclosed is a corresponding CPR method.

Or in situations where the patient may have improved enough to where the compressions are no longer needed.

Abstract: A cardiopulmonary resuscitation (“CPR”) device that includes a chest compression mechanism, a support structure, and a plurality of inflatable support pads. The chest compression mechanism is configured to deliver CPR chest compressions to a patient. The support structure includes a base member configured to be placed underneath a patient, and a leg configured to support the chest compression mechanism at a distance from the base member. The plurality of inflatable support pads are configured to provide lateral support to a patient's chest during use of the CPR device. Each support pad within the plurality of support pads includes a holder configured to retain and at least partially surround the adjacent support pad.
