Referring to fig. 1 to 3, the portable respiratory system provided in this embodiment includes a filtering device 1, an air outlet channel connector 2, and a portable ventilator 3;
the filtering device 1 is connected with an air inlet of the portable respirator 3; through filter equipment 1 to ensure the air quality of input breathing machine, improve the life-span of breathing machine, also can ensure the air quality of breathing machine output. Preferably, the filter layer of the filter device 1 can be replaced to select a proper filter layer according to the actual air quality of the time and place of using the breathing machine, so as to improve the service life of the filter device 1 and the stability of the air quality output by the breathing machine.
The air outlet channel connecting piece 2 is connected with the air outlet of the portable respirator 3. Alternatively, the gas outlet pipe 400 includes two gas outlet ends, i.e., a first gas outlet end 411 and a second gas outlet end 421, and the gas outlet pipe connector 2 includes two gas inlet ends, i.e., a first gas inlet end and a second gas inlet end, respectively. The two air inlet ends are converged into an air outlet end of the air outlet channel connecting piece 2; by combining the two air outlet pipelines outside the breathing machine, the volume of the breathing machine can be reduced, and the portability of the breathing machine can be improved.
The portable respiratory system of the present embodiment has the advantages of the portable ventilator 3 of embodiment one, and the advantages of the portable ventilator of embodiment one disclosed are not repeated here.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
