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.

CPR chest compression system

A CPR machine () is configured to perform, on a patient's () chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (), and a driver system () configured to drive the compression mechanism. A force sensing system () 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 (). An optional chest-lifting device () 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.

The present disclosure includes various examples for cooling electronics within a medical device while preventing or reducing the risk of an interior of the medical device being contaminated with a pathogen. The present disclosure includes a medical device having an air deflector to deflect potentially contaminated air from infecting a patient or caregiver. The present disclosure also includes medical devices with disinfectant devices installed to disinfect air either before entering the medical device or before exiting the device. Other examples of the present disclosure include medical devices that are sealed from outside air and fluids, and which may include a cooling device on an exterior surface which may be cleaned and/or removed after each use.

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 also includes a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. An advantage can be when the attendant checks in situations where the condition of the patient might have changed, and an adjustment is needed. Or in situations where the patient may have improved enough to where the compressions are no longer needed.

The disclosed CPR devices, systems, and methods adjust a compression depth of a compression mechanism to account for chest collapse of the patient receiving CPR. Compression depth can be adjusted up to a maximum depth in some examples. The compression depth can also be adjusted linearly or non-linearly as the zero point or starting position of the patient's chest changes due to chest collapse. Other factors can also be used to adjust the compression depth such as patient parameters that can be observed by a rescuer or sensed by sensors wirelessly connected to or integrated into the system. CPR devices that include active decompression can also use the disclosed techniques for adjusting the chest compression depth as the patient's chest collapses.

Mechanical CPR with selective zero-position and compression depth adjustment

A CPR chest compression system includes a retention structure that retains the body of a patient, and a motor and a compressor that can perform CPR compressions to the chest of the patient. The motor is powered by a battery that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires. Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in example configurations where the components are transparent to X-Rays.

In embodiments, a Cardio-Pulmonary Resuscitation (CPR) system includes a retention structure, a compression mechanism coupled to the retention structure and a backboard. The retention structure and the backboard can be assembled together so as to form a closed loop that surrounds the patient's torso, and a piston of the compression mechanism is movable towards and away from a chest of a patient. In addition, the CPR system has a stabilizing member, and a coupler configured to couple the stabilizing member to the backboard. The stabilizing member can prevent the retention structure from tilting while the CPR system delivers chest compressions to the patient.

Chest compression machine systems and methods adjust the administration of patient treatment based on received physiological parameter measurements, such as a CO2 measurement. Adjustment of the administered chest compressions can include adjusting one or more chest compression parameters, such as the depth of the administered compressions, the administration of active decompressions, adjusting the height of active decompression, adjusting the rate of compressions and/or active decompressions and/or other changes to one or more properties, or characteristics, of the administered chest compressions and/or active decompressions.

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.
