Abstract: A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.

Abstract: A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

The device includes: an all-polymer humidification chamber; a heating element positioned independently and proximate to the humidification chamber; a base unit supporting the humidification chamber; a computer that sends adjustment instructions to a water filling valve coupled with the humidification chamber; a plurality of sensors determining light within the humidification chamber and coupled with the base unit; an airflow conduit coupled with the humidification chamber; a heater wire within the airflow conduit; and an insulation material with grooves thereon surrounding the heater wire. The adjustment instructions instruct the water filling valve to self-adjust to meet a predetermined water level objective. The airflow conduit delivers gas to the patient. The heater wire heats the gas being delivered. The grooves on the insulation wire wick water within the humidification chamber away to re-evaporation regions.

Abstract: The present invention provides a chamber having at least one operator hand access port; the port comprising a port aperture located within the chamber wall; and at least two flexible non-resilient lightweight sealing gas-tight flaps (SFs), disposed the same plane of the port aperture in an overlapping manner, entirely enclosing the port aperture; each of the SFs is defined by a port aperture edge and chamber edges; the chamber edges are anchored to the chamber wall along more than half of the perimeter of the flap, at a distance from the center of the port greater than the radius of the port and beyond its perimeter; the port aperture edge of each flap is stretched across an entire chord of the port aperture; stretched port apertures edges define an interior access zone, disposed the same plane of the port aperture, characterized solely by the port aperture edges.

Abstract: An apparatus (e.g., nebulizer) for aerosol delivery of a substance (e.g., a drug to a patient) has a mouthpiece (36); a chamber (34) holding a substance; a flexible membrane (38) having a plurality of apertures; and a vibrator (44) for vibrating the flexible membrane to form a flow of aerosol droplets of the substance that are ejected through the apertures and to the mouthpiece. The vibrator may be a piezoelectric element. A magnetic member (54) is provided on the flexible membrane and is configured to magnetically couple the flexible membrane to the vibrator. The magnetic member allows replacement of the membrane, without wasting the piezoelectric element.

Abstract: This disclosure describes systems and methods for monitoring and evaluating ventilatory data to provide useful notifications and/or recommendations. Indeed, many clinicians may not easily identify or recognize data patterns and correlations indicative of certain patient conditions or the effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate adjustments that may address certain patient conditions or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the occurrence of high-delivered VT, during various types of ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect an occurrence of and potential causes for high-delivered VT, and may subsequently issue suitable notifications and/or recommendations.

The receptacle includes a support block having a well shaped to receive a valve stem extending from a container of medicament and an actuator finger extending upwardly in the receptacle adjacent the support block. The actuator finger is adapted to actuate a dose counter coupled to the container.

Abstract: A filtering face mask 10 that has a harness 14 and a mask body 12. The mask body 12 includes a filtering structure 18 and a cup-shaped shaping layer 20 where the latter comprises a closed cell foam layer that has a plurality of fluid permeable openings 22 located in it. The openings 22 are surrounded by recessed regions 31. The filtering structure 18 does not make substantial contact with the shaping layer 20 at the recessed regions. The shaping layer 20 makes contact with the wearer's face at the mask body perimeter 19 when the respirator is being worn. The use of a foam shaping layer that has openings surrounded by recessed regions provides sufficient structural integrity or stiffness to prevent mask body collapse during respirator use while also exhibiting a low pressure drop and rapid fluid distribution of air within the mask to allow for low breathing resistance and extended wearer comfort.
