摘要： A fluid passage/stop body, component, housing and apparatus, a ventilation treatment device, and an oxygen supply control method. The fluid passage/stop body comprises a sliding plate and a flexible connecting member; the flexible connecting member is connected to the sliding plate; the flexible connecting member is used for connecting to a first channel wall of a first fluid channel of a fluid passage/stop apparatus; and the sliding plate is used for moving, driven by the pressure of a fluid in the first fluid channel, to drive the flexible connecting member to flexibly deform. The fluid passage/stop body is simple in structure, can drive, in actual use, a passage/stop member to safely and reliably achieve the passage/stop of a fluid, and can significantly improve, in a ventilation treatment device, the safety of oxygen supply of the ventilation treatment device.

摘要： An emergency ventilation system ventilates a patient and includes a chamber housing defining a breathing chamber; a piston; and a motor operably connected to the piston. The motor applies an exhalation force to move the piston in an exhalation direction applies an inhalation force to move the piston in an inhalation direction. The piston increases air in the breathing chamber as the exhalation force is applied and decreases air in the breathing chamber as the inhalation force is applied. An exhalation check valve allows airflow from the air source to the breathing chamber and not to allow airflow from the breathing chamber to the air source as the inhalation force is applied. An inhalation check valve allows airflow from the breathing chamber to the air output and not to allow airflow from the air output to the breathing chamber as the exhalation force is applied.

摘要： In accordance with the present invention, there is provided an adaptor or attachment which is suitable for integration into the patient circuit of a ventilation system, such as a non-invasive open ventilation system, is configured for attachment to any standard ventilation mask, and is outfitted with a jet pump which creates pressure and flow by facilitating the entrainment of ambient air. The adaptor comprises a base element and a nozzle element which are operatively coupled to each other. The base element further defines a throat and at least one entrainment port facilitating a path of fluid communication between the throat and ambient air. The nozzle element includes a jet nozzle, and a connector which is adapted to facilitate the fluid coupling of the nozzle element to a bi-lumen tube of the patient circuit. The connector includes both a delivery port and a sensing port. The jet nozzle and the delivery port collectively define a delivery line or lumen which fluidly communicates with the throat of the base element, and is placeable into fluid communication with the delivery lumen of the bi-lumen tube.

摘要： Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

摘要： A gas-washout vent includes a housing with a first wall with one or more passages through the wall configured to provide fluid communication with a portion of the patient interface system exposed to a therapy pressure. The passages include respective first openings on a first surface of the first wall. The housing at least partially defines a second opening in communication with ambient atmosphere. A diffusing material is located at least partially within the housing to be adjacent the first surface. A surface of the diffusing material facing the first surface is spaced away from the first surface by a gap that extends to provide a fluid communication between all of the first openings and between all of the first openings and the second opening. The housing is configured so that air is prevented from flowing out of the housing at all areas directly opposite each of the first openings.

摘要： Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patient's respiratory cycle in use. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads.

摘要： A portable ventilator module is provided and includes a data module capable of artificial intelligence (AI) and/or machine learning (ML). The ventilator module is detachably attachable to an anaesthesia module to enable a single device to collect data from a patient in critical care and theatre environments. Also provided is a system for the unbroken acquisition of data from the entire patient stay in critical care, emergency areas and theatres in a single device by including a data module capable of AI or ML within a portable ventilator module, wherein the portable ventilator module can provide life-sustaining ventilation support to a patient in critical care and wherein the portable ventilator can dock with an anaesthesia module to provide anaesthesia during operations in theatre so that a machine change from an ICU ventilator to a separate anaesthesia machine and back again is not required, thereby avoiding data loss.

摘要： A high-flow respiratory therapy system includes a blender arranged to receive a first gas and a second gas and to output a combination thereof as a delivered gas to a patient respiratory interface, an airflow source for providing a flow of air to the blender as the first gas, a valve operable to provide oxygen gas from an oxygen gas source to the blender as the second gas, a heater operable to heat the delivered gas at the patient respiratory interface, a pulse oximeter, and a controller configured to execute a learning procedure in response to a trigger. The learning procedure may include varying a parameter of the airflow source, a parameter of the valve, and a parameter of the heater and determining a recommended parameter based on one or more measurements of the pulse oximeter. The controller may output a recommendation to adjust the recommended parameter.

摘要： In one embodiment, a method for accurate leak estimation in a flow generation system includes measuring a total flow through the flow generation system, measuring a pressure in in the primary flow circuit of the flow generation system, determining when the measured pressure is within a predetermined threshold of EPAP, and calculating an intentional leak flowrate and an unintentional leak flowrate based on the relationship QFS(t)=QIL(t)+QUL(t) when the measured pressure is within the predetermined threshold. In another embodiment, a flow generation system includes in one embodiment an airflow generator connected in-line to a flow sensor, a pressure sensor and a patient interface connection by a first gas flow circuit, and a controller electrically coupled to the airflow generator, the flow sensor and the pressure sensor.
