  • Patent number: 12127999
    Abstract: 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.

  • Publication number: 20240065934
    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.

  • Publication number: 20230355468
    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. 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.

  • Publication number: 20230320928
    Abstract: 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.

  • Publication number: 20220280379
    Abstract: Embodiments of a Cardio-Pulmonary Resuscitation (“CPR”) device are disclosed. A CPR device can include a compression mechanism configured to perform successive CPR compressions on a chest of a patient, the compression mechanism including a support portion configured to be placed underneath a patient, a piston, and a contact surface configured to make contact with the chest at a first orientation with respect to the support portion; and a controller communicatively coupled with the compression mechanism. The controller can be configured to receive at least one input and determine whether the first orientation of the contact surface should be adjusted based on the at least one input. The controller can further, responsive to a determination that the first orientation of the contact surface should be adjusted, cause the contact surface to move so that the contact surface makes contact with the chest at a second orientation with respect to the support portion.

  • Patent number: 10849820
    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.

  • Publication number: 20200330325
    Abstract: A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is varied based on feedback gathered from physiological sensors that detect physiological characteristics of the patient during treatment.

  • Patent number: 10792215
    Abstract: A mechanism attached to a mechanical CPR device can be automatically attached to the patient's torso. The mechanical CPR device can extend the mechanism to a first position at which the mechanism comes into contact with the patient's torso. The mechanism can be further extended until a first threshold is reached. The mechanism can be retracted to the first position. The mechanism can be further retracted from the first position until a second threshold is exceeded. The mechanism can then be extended to a second point at which the second threshold is no longer exceeded. The mechanism may comprise a suction cup or sticker plate, and may be attached to an end of a piston of the mechanical CPR device.

  • Patent number: 10695264
    Abstract: A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is purposely sub-optimal for circulation at least some of the time, and especially when it is detected that the patient has regained consciousness. An advantage can be that the patient may thus faint again, and therefore perceive less of the unpleasant experience of the mechanical chest compressions that the CPR system continues to perform on them as it preserves them alive.
