Publication number: 20240082104Abstract: Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user.Type: ApplicationFiled: November 10, 2023Publication date: March 14, 2024Inventors: Michael Austin Johnson, Jason Adams, Jean-Pierre Delplanque, Justin Koos, Gregory Rehm

Publication number: 20230363374Abstract: An improved packaging assembly for storing, distributing, treating, mixing, and dispensing tissue and/or cellular material and/or implantable material. The packaging assembly may include pouches, tubes, and a bag made of a sealable, flexible polymeric material that is open at one end and a needle-free swabable connector attached to the pouch at the other end and acting as a port to allow for the introduction or discharge of biological solutions, rinsing solution, and/or preservation solutions into the packaging assembly. The designed thickness of the wall of the packaging assembly facilitates efficient heat/cold transfer, which is useful for successful controlled rate freezing, quick thawing, and resuscitation of viable cells or tissue. The packaging assembly is also useful for combining additional biological fluids with the cellular material or tissue, and for efficient mixing of the biological fluids with the tissue and/or cellular material in the assembly.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Applicant: LifeNet HealthInventors: Silvia Chen, Austin Johnson, Roberto Bracone
