A disposable filter (100), for use in a breathing circuit of a ventilator, includes a filter housing (110), which encloses a filter material (112) of the disposable filter. The filter housing has a first filter opening (118) and a second filter opening (119) for the respective connection of a gas-carrying (gas-guiding) component, especially of a respective tube, for a gas to be carried through the disposable filter. The filter material is arranged between the first filter opening and the second filter opening. The disposable filter has on the filter housing an imprint (120), which is arranged on the filter housing by a printing process, and which forms a structured surface (122). The structured surface can be written on and includes at least seven check (marking) areas (124).

An exhaust apparatus for connection to a personal protection respiratory device that defines a filtered air volume adjacent to the face of a wearer and comprises at least one exhalation, the apparatus comprising a blower in fluid connection with the at least one exhalation valve, the blower being responsive to the wearer's respiratory cycle to draw a substantial portion of the wearer's exhaled breath through the at least one exhalation valve wherein, in response to the wearer's respiratory cycle, the blower operates throughout the wearer's exhale breath, or a substantial period thereof, and does not operate throughout the wearer's inhale breath, or a substantial period thereof

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.

An emergency ventilator for artificially ventilating patients in the event of a medical emergency, including: - a housing with an ambient air suction opening and a ventilating gas outlet opening, - a fan which is designed and is arranged in the housing so as to convey ambient air from the ambient air suction opening to the ventilating gas outlet opening, - an air filter which is designed to purify suctioned ambient air and which is arranged in the housing downstream of the ambient air suction opening in the flow path of the ambient air, and - an energy storage device for supplying the fan with energy in order to operate same, wherein the air filter is received in the housing in an accessible manner through a housing opening, which is closed but can be opened by a housing cover, and so as to be replaceable in an intended manner, and the energy storage device is received in the housing in an accessible manner through the housing opening, which is closed but can be opened by the housing cover, and so as to be replaceable in an intended manner, the air filter and the energy storage device can be accessed through a common housing opening, the common housing opening being selectively closable and openable by a common housing cover.

An artificial ventilation system and relative control method, the ventilation system is suitable for application to CPAP (Continuous Positive Airway Pressure) breathing helmets to provide artificial ventilation to a patient with respiratory difficulties destined for so-called “sub-intensive” therapies. The artificial ventilation system provides a fully automated ventilation and does not require frequent checks by specialized medical personnel. The relative control method allows automatic control of the entire artificial ventilation system and implements innovative control strategies and techniques.

Systems and methods are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a housing defining a sump, the sump configured to hold a self-contained supply of liquid anesthetic agent, a heating element electrically coupled to an electrical mating component, a gas inlet passage and a gas outlet passage, a manifold fluidically coupled to the gas inlet passage and the gas outlet passage, the manifold coupled to the housing and forming a gas-tight seal with the sump, and a quick disconnect pneumatic system coupled to the gas inlet passage and the gas outlet passage, sealing the gas inlet passage and the gas outlet passage from atmosphere.

The present invention includes a device for hypoxia training comprising: one or more electrochemical cells each comprising: a cathode and an anode separated by a proton exchange membrane, each of the anode and cathode in communication with an input and an output, wherein the input of the cathode is in fluid communication with ambient air, and wherein the input of the anode is in fluid communication with a source of liquid water; a power supply connected to the one or more electrochemical cells; and a mask in fluid communication with the output from the cathode of the one or more electrochemical cells, wherein oxygen is removed from the ambient air during contact with the cathode when hydrogen ions separated from liquid water by a catalyst on the anode convert oxygen in the ambient air into water.

Respiratory diseases affect a large part of world population, especially in developing world. In this invention, we present a breathing support system to provide life-saving support to such patients. The system automates and regulates the use of a bag valve mask (commonly known as an ambu bag). The system uses mechanical actuators, sensors and a smart feedback control mechanism to automate and regulate the operation of the ambu bag to implement core functions of mechanical ventilation for life-saving applications. The system can also be used to provide better breathing support to newborns (e.g. to prevent hypoxia). The system can be used to save hundreds of thousands of lives in the developing world, in emergencies and during transportation globally.
