Abstract:
The function of a respiration system, with a patient port (1) with connected inspiration branch (3) and expiration branch, is checked. A rebreathing line (9) connects the inspiration branch to the expiration branch. A reservoir (25) is connected to a reservoir port (27) in the rebreathing line. An actuatable control valve (29) is provided in the rebreathing line between the expiration branch and the reservoir port. A pressure sensor (33) is connected to the rebreathing line. A control unit (39) is connected to the control valve and to pressure sensor. The process includes closing the control valve for a preset inspiration time and opening it for a preset expiration time. The value sent by the pressure sensor is detected with the control valve opened during the expiration time and compared with a preset first threshold valve. An error message is generated when the value sent exceeds the first threshold value.
Abstract:
A portable, compact closed circuit ventilation device for manual ventilation of a patient undergoing a surgical or medical procedure that requires sedation as well as emergency management of respiratory failure. One example embodiment includes a closed breathing circuit having a manually squeezable bag, a carbon dioxide absorption canister, a plurality of valves, a gas port and a plurality of sensors for measuring Tidal Volume (TV), Peak Airway Pressure (PAP) and End Tidal CO2 (ETCO2). Another example embodiment includes an open breathing circuit having a bag, valves and sensors. A monitor displays the sensor measurements during the respiratory phases. In a spontaneously breathing patient the device may be used to assess the adequacy of patient's respiratory efforts. During manual or assisted ventilation, the monitor assures safe and efficacious ventilation by the closed breathing circuit.
Abstract:
The present disclosure pertains to a ventilation therapy system configured to control a pressure or flow generator to apply an intra-pulmonary percussive ventilation therapy regime to a pressurized flow of breathable gas during baseline ventilation therapy. The ventilation therapy system is configured to automatically control the pressurized flow of breathable gas. The system may automatically control an extent of hyperinflation during IPPV in a subject. The system is configured such that therapy set points, alarm settings, and/or other factors are automatically adjusted during the application of IPPV relative to the set points and alarm settings during baseline ventilation therapy. In some embodiments, the system comprises one or more of a pressure or flow generator, a subject interface, one or more sensors, one or more processors, a user interface, electronic storage, and/or other components.
Abstract:
The present invention relates to an electrically operable resuscitation device comprising a pump including a rigid cylinder including at least one gas inlet and at least one gas outlet, a piston to travel in said cylinder, and at least one valve, the or each valve configured to allow gas to be displaced into said cylinder through said at least one gas inlet during at least one of a first stroke direction and second stroke direction of said piston in said cylinder, and for allowing gas to displaced through said at least one gas outlet during an opposite of said at least one of the first stroke direction and second stroke direction of said piston in said cylinder; a motor, selected from one of a stepper motor and feedback motor and stepper motor with feedback and linear motor, operatively connected to said piston to move said piston in said cylinder; a patient interface in ducted fluid connection with said pump to receive gas via said at least one gas outlet and to deliver said gas to said patient.
Abstract:
A pressure relief device comprising a valve configured to resiliently deform in response to a predetermined pressure; and a sound dampener configured to dampen a sound generated by the valve when the valve resiliently deforms in response to said predetermined pressure.

The present invention further provides a combination of pharmacologically active agents and a pharmaceutical composition.
Abstract:
A medication delivery apparatus and system for the application of a local anesthetic to a treatment site, such as an airway, and method for use of same are disclosed. In one embodiment of the medication delivery apparatus and system, a reservoir supplies a local anesthetic to a lower chamber of a housing wherein an ultrasonic transducer applies ultrasonic energy thereto, thereby nebulizing the local anesthetic. A control valve is interposed between a source of positive pressure air and an upper chamber of the housing to selectively apply positive air pressure to the upper chamber. Upon the application of positive air pressure, the airflow delivers the nebulized anesthetic to a patient's airway by way of a laryngoscope side port coupling, laryngoscope vacuum port coupling, or catheter coupling, for example. The application of local anesthetic, itself, in this nebulized manner mitigates gaging, chocking, aspirating, bucking and laryngospasms.
Abstract:
An inhalation device having a base unit, a mouthpiece, and an aerosol head is provided. The base unit has an air inlet, an air outlet opening, a groove for receiving the mouthpiece, and key lock member(s). The mouthpiece has two segments: a first segment which is insertable into the groove of the base unit and has an air inlet opening and a lateral opening for receiving an aerosol generator and a second segment with an aerosol outlet. The aerosol head has an aerosol generator, a liquid reservoir, and key lock member(s) complementary to those of the base unit. The base unit, mouthpiece and aerosol head are connectable with one another such that when engaging the members of the key lock with the complementary members, the aerosol generator is inserted into the lateral opening of the mouthpiece.
Abstract:
A treatment system includes a delivery device which delivers a combination of a breathing gas and frozen ice or other particles to a patient in order to induce hypothermia. The treatment system also includes a temperature system for measuring the temperature of exhaled gases and a controller which can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured exhalation gas temperature.
Abstract:
The invention concerns a connector for connecting respiratory ducts together such that they are placed in fluid communication. The connector comprises a first conduit having a female connector end and a second conduit having a male connector end adapted to be received within the female connector end of the first conduit such that the male and female connector ends form a common conduit having an inner surface formed at least in part by the male connector end. The male connector has a retaining formation which is adapted to abut a corresponding formation of the female connector so as to resist separation of the first and second conduits whilst permitting relative rotation there-between when connected. The inner surface of the male connector may comprise a gas washed surface in use. The engagement formation is preferably a recessed area of the female connector, which may be generally annular in shape. In one embodiment, the member(s) may comprise a valve seat. The invention also concerns a breathing circuit comprising the connector.
