摘要:
A breathing device, comprising a mouthpiece forming a breathing channel, to form a connection between a first end and a second end of the mouthpiece; the first end being configured for a user breathing into the mouthpiece through a breathing opening; an at least partly flexible rebreathing air chamber attached to the second end of the mouthpiece, thereby being in fluid connection with the breathing channel; the rebreathing air chamber being formed by at least partly flexible wall section(s), the at least partly flexible rebreathing chamber having at a first wall section, being permeable to gas by a plurality of pores provided in said wall section and/or the mouth piece comprising one or more though going openings.

The invention relates to an apparatus for supplying breathing air to a person, comprising a rebreathing system arranged in the air supply circuit, which removes CO 2 at least in part present in the person's expiration air by means of a CO 2 absorber, and treats the expiration air such that the treated air can be supplied to the person again as inhalation air, and comprising a condensate collection container (9), in which the water forming in the air supply circuit can be collected. The described technical solution is characterized in that the condensate collection container (9) is arranged at least in part below a reaction zone (17) of the CO 2 absorber (1), and in that at least one heat exchanger (10, 14) is provided in the CO 2 absorber, via which heat from the air, which flows through the CO 2 absorber and is heated as a result of the exothermic CO 2 absorption reaction occurring in the reaction zone of the CO 2 absorber, is dissipated.

A nasal delivery device can include air-receiving section that has a first passageway therethrough to allow air to pass through the air-receiving section, a powder-reservoir receiving section sized to receive a powder reservoir, and a powder-delivery section that has a second passageway therethrough to allow aerosolized powder from the powder reservoir to pass through the powder-delivery section. The first passageway can have a first end and a second end, with the first end being further from the powder-reservoir receiving section and the second end being at or near the powder-reservoir receiving area. The second end of the air-receiving section can include a flattened region so that air exiting the air-receiving section has a generally flattened profile.

High flow therapy is used to treat Cheyne-Stokes respiration and other types of periodic respiration disorders by periodic application of high flow therapy, adjustment of high flow therapy flow rates and/or periodic additions of CO2 or O2 into the air flow provided to the patient.

The present invention relates to a method and apparatus for facilitating anaesthesia, particularly in Re-Breather anaesthetic circuits. A problem with Re-Breather circuits is that their dynamic response can be relatively slow. The dynamic response is the response of the circuit to delivering changes of anaesthetic concentration. In current circuits, Fresh Gas containing anaesthetic is delivered into the circuit and may be substantially diluted by the gas already present in the circuit. It is therefore difficult to achieve a rapid increase of anaesthetic concentration for delivery to the patient. In the present invention, an accumulator is placed in the Re-Breather circuit to accumulate Fresh Gas containing anaesthetic as it is introduced into the circuit, adjacent an inhalation conduit to the patient. Fresh Gas containing high concentrations of anaesthetic is therefore immediately available to the patient.

An anesthetic breathing apparatus and system having a patient circle system (7) for re-breathing exhaled gases by a patient is disclosed having a volume reflector (26), a fresh gas delivery line (18), and a gas sensor unit (640) arranged to measure a gas stream upstream a fresh gas connection (19) and downstream said reflector unit (26) and provides a signal for detection of a reflector driving gas (RDG) crossing over said volume reflector (26) during inspiration based on said at least one property of said gas stream measured by said gas sensor unit (640). Appropriate action may be taken based on this measurement, for instance in disclosed methods.
摘要:
A device, system (10) and method for isolating a ventilator from one or more patients in which the delivery conditions of gas delivered to an isolation device from a ventilator may drive the delivery of breathing-gas delivered to one or more patients, the breathing-gas having the same or different delivery conditions. In one embodiment, an isolation device (10) may have a housing (13) and a movable partition (16). The movable partition (16) may be joined to the housing (13). The movable partition (16) may have a patient side (22) on a first side of the partition (16) and an actuating side (25) on a second side of the partition (16). The isolation device (10) may include an inlet pressure regulator (82) on the actuating side (25) and/or an exhaust pressure regulator (84) on the patient side (22). These regulators (82,84) may alter the delivery conditions (including, but not limited to, pressure and volume) of breathing-gas delivered to a patient.
