Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the drawings.
As shown in fig. 1, an offline collection device for expired air comprises a three-way collection tube 1 and a filter cartridge 2.
Specifically, the three-way collecting tube 1 includes a tube body 11, an exhalation nozzle 12, an air outlet nozzle 13 and an air inlet nozzle 14, which are located at three ends of the tube body 11 and are communicated with each other. Wherein, the pipe body 11 is preferably a rigid polyvinyl chloride pipe body; the breathing nozzle 12 is used for being communicated with the air outlet of the breathing mask in a sealing way; the air outlet nozzle 13 is used for being in sealed communication with an air collecting bag opening which is internally provided with a gas reversing valve; the intake nozzle 14 communicates with the filter cassette 2.
Further, the exhalation nozzle 12 is connected with the air outlet of the breathing mask in a threaded fit manner; the gas collecting bag mouth can be directly connected with the gas outlet nozzle 13 in a sealing way through plugging or screwing, and can also be connected with the gas outlet nozzle 13 through a gas pipe.
In this expiration off-line collection device, the filter cartridge 2 is integrated into one piece's plastic carton, including hollow box body 21 and the connector 22 that is located the upper end of box body 21 and communicates the box body 21 inside and outside. The box body 21 is a cylinder, a cuboid or a polygonal prism, the lower end of the box body is open, and a filtering component 23 is arranged inside the box body; the connector 22 is in sealed communication with the air inlet nozzle 14, and the one-way valve 3 is connected in a sealed manner inside. As an embodiment of the utility model, the outside of suction nozzle 14 is provided with the external screw thread, and the inboard of connector 22 is provided with the internal thread, is connected through screw-thread fit between connector 22 and the suction nozzle 14.
