Embodiment Construction

[0050] The schematic diagram in FIG. 1 shows that the breathing mask 3 is fixed on the user 1 via a headgear device 2 . The respirator 3 in this example is implemented in such a way that it covers the nose area, but does not cover the mouth. It is also possible to implement the breathing mask 3 in such a way that the mouth opening is also covered. Breathing gas may also be delivered via other kinds of structures, such as mouth inserts, or simply nasal pads secured to the ambient area around the nostrils.

[0051] The breathing mask 3 is connected via a hose connection plug 4 and a flexible tube 5 to a device 6 for delivering breathing gas (in this case filtered ambient air). The device 6 includes a feed device, here embodied as a blower 7 , which communicates on the suction side with the environment via a suction line 8 and a suction filter device 9 .

[0052] On the pressure side, the blower 7 is connected to a pressure line part 10 . The pressure line part 10 leads via a ...

Abstract

The invention is directed to a device (6) for furnishing a breathing gas at alternating pressure levels having a feeding device (7) for feeding the breathing gas, a pressure adjusting device (14) for triggering the feeding device set-point breathing gas pressure signal, furnishes the breathing gas at a set-point, a pressure specification device (14) for generating a pressure signal, and parameter-determination means (12) for furnishing parameters representative of at least of the instantaneous pressure (p), the progression of time (t), and the instantaneous breathing gas flow (v), wherein the pressure specification device includes a computer circuit configured such at least in the expiratory phase, an adjustment of the pressure is effected on the basis of a dynamic or nonlinear pressure guidance function, which takes parameters into account that are indicative of the breathing gas flow and the progression of time and as a result, the tendency to lowering the breathing gas pressure in conjunction with the extent of the breathing gas flow decreases with increasing progression of time.

Description

technical field [0001] The invention relates to a device for supplying breathing gas to a user. The invention also relates to a method commonly used among users for adjusting the static pressure of the breathing gas so that the breathing gas pressure is higher than that of the surrounding environment during at least some phases. Alternate the stress level while stressing. Background technique [0002] Especially for the treatment of sleep-related breathing problems, it is known to raise breathing gas, such as filtered ambient air, above A pressure level of ambient air pressure is supplied to a patient. [0003] By raising the breathing gas pressure above the ambient pressure, typically in the range between 4-18 mbar, it is possible to prevent blockages in the upstream region of the airway. The reduction in the likelihood of blockages occurring in the upstream region of the airway when breathing gas is supplied at elevated pressure levels is based on an effect known as pneu...
