A face mask (also called full face) for respiratory therapy, in particular for non-invasive mechanical ventilation, has a low value of CO.sub.2 rebreathing. The mask includes a shaped shell to cover at least the mouth, the nose and the eyes of a patient when the mask is worn, and includes, on said shaped shell an inlet fitting for the connection to a pipe through which a ventilation apparatus supplies the mask with a mixture of air and oxygen, and an outlet fitting, separate from said inlet fitting, for the discharge of air exhaled by the patient. With this arrangement, the mask allows drastically reducing the phenomenon of carbon dioxide rebreathing, which is very harmful for the patient subjected to ventilation.

The present invention relates to a method for controlling a thermoregulated ventilation circuit (100) equipped with a control unit (40) and comprising an active humidifier (10). The active humidifier (10) further comprises, in turn, a cartridge (20) equipped with a humidification chamber (21) adapted to contain water to be heated for the humidification of the air through a heating element (30), and the thermoregulated circuit (100) further comprising at least one intake tube (120) for conveying the air exiting said cartridge and provided with heating means (123) for heating the air exiting said cartridge (20). The method according to the present invention is characterised in that said control unit (40) receives in input the patient's temperature data (Tp) detected by a patient's temperature probe (132) and regulates the operation of said heating element (30) of said cartridge (20) and the operation of said heating means (123) of the air exiting said cartridge (20) as a function of said patient's temperature (Tp).

This disclosure relates to a mask which delivers pressurized airflow to a patient. The mask includes a central portion and a wing projecting from the central portion. The wing is configured to adhere to a patient's cheek.

A clamp (1) releases or blocks a fluid connection as desired. A clamping tube (3, 4, 5.1, 5.2, 7.1) of the clamp (1) includes a blocking fluid guide element (7.1) and two connecting fluid guide elements (3, 4). The blocking fluid guide element (7.1) is connected in a fluid-tight manner to the two connecting fluid guide elements (3, 4). A clamping unit of the clamp (1) includes two clamping components (8.1, 10.1, 8.2, 10.2). The blocking fluid guide element (7.1) is located between the two clamping components (8.1, 10.1, 8.2, 10.2). In a releasing state of the clamping unit, the blocking fluid guide element (7.1) establishes a fluid connection between the two connecting fluid guide elements (3, 4). In a blocking state, the two clamping components (8.1, 10.1, 8.2, 10.2) prevent a flow of fluid through the blocking fluid guide element (7.1).

A patient interface includes a plenum chamber, a seal-forming structure, and a positioning and stabilising structure to provide a force to hold the seal-forming structure in a therapeutically effective position on a patient's head. The positioning and stabilizing structure includes a superior strap portion, an inferior strap portion, and a posterior connecting strap portion connected to or formed integrally with the superior strap portion and the inferior strap portion. The posterior connecting strap portion is constructed from a mesh material that is different than the material used to construct the superior strap portion and the inferior strap portion. The posterior connecting strap portion has a greater stretch capability than the superior strap portion and a lesser stretch capability than the inferior strap portion. The stretch capabilities allow the positioning and stabilizing structure to be removable from the patient's head when the loop engages the connection portion.

The invention relates to providing novel functions to the coaxial breathing circuits which at present do not comprise water traps, by adding a closed system water trap designed to have an inkwell shape and a lung pressure measurement port to said circuits wherein the fluid collected in the bottle section can be discharged without having to open the bottle by means of a drainage luer port located at the base of the bottle and a needleless apparatus that has been inserted into the port, and an injector.

A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

A neck strap, a crown strap assembly and a headgear for a breathing mask. The neck strap for a headgear includes a one-piece main body adapted to engage a patient's neck, first and second lower connection portions adapted to connect to first and second lower mask connection straps, and first and second upper connection portions adapted to connect to respective first and second lateral crown straps.

A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.

An attachment for a tracheal cannula, the attachment surrounding a cavity, the attachment being open both in a coupling area of the attachment as well as in an orifice area of the attachment, differing in location from the coupling area, for providing an access to the cavity, the attachment having in the coupling area a latching formation, which is designed for the releasable connection to a mating latching formation of the tracheal cannula, the coupling area surrounding a section of the cavity, the section of the cavity surrounded by the coupling area being centrally penetrated by a virtual coupling axis, the coupling axis defining an axial direction along its path, defining a plurality of radial directions orthogonally to its path and defining a circumferential direction running around it, the coupling area having at least one support section, on which the latching formation and a force application area are situated in such a way that by exerting an actuating force on the force application area in the radial direction toward the coupling axis, the support section is displaceable between two positions of different radial distance of the latching formation situated on the support section from the coupling axis; the force application area and the latching formation displaceable by an exertion of force on the force application area of the same support section are situated along the coupling axis at an axial distance from each other.
