Abstract: A mesh nebulizer that nebulizes and ejects a medicinal liquid through a mesh portion, includes a main body including a vibration portion including a vibration surface, and a medicinal liquid pack to be detachably mounted on the main body. The medicinal liquid pack includes a lid in which the mesh portion is provided, and a medicinal liquid container that includes a recessed portion that is open toward the mesh portion and is covered by the lid, the medicinal liquid being contained in the recessed portion. At least a portion of a bottom surface of the recessed portion of the medicinal liquid container that is to oppose the vibration surface is made of a stretchable material. When the medicinal liquid pack is mounted on the main body, the stretchable material of the bottom surface stretches, allowing the vibration surface to approach the mesh portion of the lid.

Abstract: An exercise assist device transitively moves a sacroiliac joint in a lateral decubitus position. The following description is provided in the context of a left lateral decubitus position. The upper right leg is placed on a stand in the lateral decubitus position, and the upper right leg is then extended transitively backward with a sacral area supported by a sacrum support pad. Since a posterior side of a lower left sacroiliac joint is slightly opened, a sacrum slides backward via a right hip joint. This improves mobility of the lower left sacroiliac joint.
Abstract: A device is disclosed for the preparation of nebulised droplets, for inhalation. The device has: a surface acoustic wave (SAW) transmission surface; a SAW transducer adapted to generate and propagate SAWs along the SAW transmission surface; and an array of cavities opening at the SAW transmission surface for containing a liquid. In operation, SAWs propagating along the SAW transmission surface interact with the liquid in the cavities to produce nebulised droplets of the liquid. Operation of the device results in a nebulised plume of droplets of average diameter in the range 1-5 ?m.

Abstract: Various methods and systems are provided for performing nasal high flow therapy. In one example, a method for respiratory support includes: delivering an air and oxygen mixture for nasal high flow therapy to a patient at a flow setting, the flow setting determined based on a peak inspiratory flow obtained during a previous, spontaneous breathing mode during mechanical ventilation of the patient. The flow setting may be a flow rate of a heated and humidified mixture of air and oxygen delivered via a high flow nasal cannula.

Abstract: A novel clinical decision support system (CDS) helps the clinician setup, maintain, and interpret esophageal pressure measurement. The esophageal pressure CDS (Pes CDS) would remind the clinician to do an occlusion test whenever the balloon is first inserted or changes dramatically. It could monitor the occlusion test and provide feedback on the performance and success of the occlusion test. Changes in the patient or monitored data can be tracked by looking for changes in the balloon baseline pressure, changes in the amplitude of the pressure waveform, or changes in the pattern of the Pes waveform. Having information from the ventilator will further increase the ability of the system to determine when Pes is changing unexpectedly.
Abstract: Concurrent treatment of obstructive sleep apnea and hypertension in a patient, via a pressure generating device, includes providing a flow of treatment gas to an airway of a patient in accordance with an initial set of flow parameters with respect to an obstructive sleep apnea mode. Responsive to determining that the patient has achieved stable breathing while receiving the flow of treatment gas, the flow parameters are increased above the initial set of flow parameters with respect to a hyper-ventilation mode. The flow of treatment gas is then provided to the airway of the patient in accordance with the increased flow parameters for a predetermined period of time. The increased flow parameters are configured to bring the patient's breath into accordance with target patient breath parameters configured to inflate the patient's lungs beyond a threshold for activating pulmonary stretch receptors of the airway of the patient.

Abstract: Technologies (e.g., devices, systems and methods) for sanitizing positive airway pressure (PAP) systems are described. In some embodiments, the technologies include a PAP delivery system comprising a hose and a PAP mask, a positive pressure supply system configured to generate a flow of pressurized air which is delivered to a user through the hose to the PAP mask of the PAP delivery system, a sanitizing system configured to sanitize one or more components of the self-sanitizing PAP system, and a PAP base unit housing, wherein one or more components of the positive pressure supply system and the sanitizing system are disposed at least partially within the PAP base unit housing.
Abstract: Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or.
