The present invention relates to a breathing assistance device for a patient.
More precisely, the invention relates to a breathing assistance device for a patient breathing in successive respiratory cycles, each respiratory cycle being defined by at least an inspiration phase and at least an expiration phase.
A variety of breathing assistance devices, which we will also generally refer to as “respirators” in this text, are available today.
Other features and advantages of the invention will become clear from the following description which is only given for illustrative purposes and is in no way limitating and should be read with reference to the attached drawings on which, in addition to FIGS. 1a to 1d and 2a to 2d which have already been commented above:
FIG. 3 is a schematic representation of a breathing assistance device according to the invention;
FIG. 4a is a three-dimensional exploded view of a gas regulating valve according to a first embodiment of the invention;
