  • Publication number: 20260144703
    Abstract: Examples of the disclosure are directed to mechanical compression devices that can adjust a location of a compression position relative to a patient. One or more of the mechanical compression devices can adjust the compression position in an adjustment plane that is generally perpendicular to a patient. Some of the mechanical compression include support columns that have actuators that can be set asymmetrically to adjust the compression position and/or can be tilted relative to the backboard to adjust the compression position. Other examples includes mechanical compression devices that have multiple actuators that can be used to adjust the compression position as well as provide compressions.

  • Publication number: 20260137589
    Abstract: A mechanical cardiopulmonary resuscitation (CPR) device that includes a central housing, a telescoping piston, and a driving component. The telescoping piston includes an outer piston sleeve structured to move toward and away from the patient's torso and toward and away from the central housing. The proximal end of the outer piston sleeve is configured to remain within the central housing when the telescoping piston extends from the central housing. The telescoping piston includes an inner piston sleeve within the outer piston sleeve that is structured to move relative to the outer piston sleeve toward and away from the patient's torso. The proximal end of the inner piston sleeve is configured extend beyond the central housing when the telescoping piston extends from the central housing. The driving component is configured to drive the telescoping piston to extend toward the patient's torso and retract the telescoping piston from the patient's torso.

  • Publication number: 20260041605
    Abstract: A backboard for a mechanical cardiopulmonary resuscitation (CPR) device having a first connector, a second connector, an elongated portion, and a position adjustment mechanism. The first connector is structured to couple to a first leg of the mechanical CPR device. The second connector structured to couple to a second leg of the mechanical CPR device. The elongated portion extends along an axis between the first connector and the second connector. The position adjustment mechanism is structured to adjust a patient position on the elongated portion in an adjustment direction that is perpendicular to the axis between the first connector and the second connector.

  • Patent number: 12533291
    Abstract: Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

  • Publication number: 20250375348
    Abstract: An adjustable-size backboard for a chest compressions device having a first connector, a second connector, and an adjustable elongated portion extending between the first connector and the second connector. The first connector is structured to attach to a first leg of a chest compression device. The second connector is structured to attach to a second leg of the chest compression device. The adjustable elongated portion includes a first portion that extends from the first connector and a second portion. The second portion is between the first connector and the second connector and is structured to slide relative to the first portion.

  • Patent number: 12485065
    Abstract: An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.

  • Patent number: 12409102
    Abstract: Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes.

  • Patent number: 12257206
    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: 20240374472
    Abstract: A piston assembly with a transversely removable suction cup, the piston assembly having a piston rod, a flange at an end of the piston rod, and a suction cup removably secured to the end of the piston rod. The piston rod has a longitudinal axis defining a longitudinal direction and a transverse direction that is substantially perpendicular to the longitudinal direction. The flange has a width in the transverse direction that is greater than a width of the piston rod in the transverse direction. The suction cup includes a receptacle configured to accept and secure the flange within the receptacle. The receptacle has an opening allowing the flange to be accepted into the receptacle in the transverse direction and to be removed from the receptacle in the transverse direction.

  • Publication number: 20240065935
    Abstract: Techniques for pairing medical devices are described. An example method includes detecting a signal indicating a physiological parameter of a subject and determining, by analyzing the signal, that a second medical device is administering a treatment to the subject. In response to determining that the second medical device is administering the treatment to the subject, the method further includes pairing a first medical device with the second medical device. In response to pairing the first medical device with the second medical device, the method further includes transmitting data to the second medical device over a wireless channel.

  • Publication number: 20240066309
    Abstract: Techniques for administering therapy and monitoring a subject based on communication between medical devices are described. An example method includes receiving, by an external defibrillator, data from a mechanical chest compression device that is administering chest compressions to a subject, determining, by the external defibrillator analyzing the data, a control parameter for controlling administration of a therapy to the subject by the external defibrillator, and administering, by the external defibrillator, the therapy to the subject in accordance with the control parameter.
