Filter bores are provided with, milipore filter is set at the filter bores, the edge shape of the slotting disk end is corresponding to the madial wall of through hole,
Sealed against each other so that inserting between the edge of disk end and the madial wall of the through hole.
Further, in addition to active carbon filter, the active carbon filter have an air inlet and an exhaust outlet,
The air inlet docks with the exhaust passage.
Further, the length of the slotting disk is more than the depth of slot.
Further, diaphragm seal made of resilient material is set in the card of the rotating disk.
Further, a mark is each provided with the outer circumference surface of the rotating disk and on the housing of rotating disk outer circumference surface
Show.
The beneficial effects of the utility model：The oxygen hood of the present utility model for facilitating gas virus sampling, including virus
The mask body that sampling apparatus and edge shape match with mouth peripheral profile, oxygen cathete is provided with the mask body
And blast pipe, the blast pipe are interconnected with the viral sampling apparatus.It is of the present utility model to facilitate what gas virus sampled
Oxygen hood, the Concentration Sampling that virus is carried out while being cured by oxygen therapy to patient is realized, and the design of viral sampling apparatus is real
The continuous beneficial effect uninterruptedly sampled is showed.
Brief description of the drawings
Fig. 1 is the structural representation for the oxygen hood that the utility model facilitates gas virus sampling；
Fig. 2 is the three-dimensional structure diagram of viral sampling apparatus on the utility model oxygen hood；
Fig. 3 is the upward view of viral sampling apparatus on the utility model oxygen hood.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-3, in the present embodiment facilitate gas virus sampling oxygen hood, including viral sampling apparatus and
The mask body 1 that one edge shape matches with mouth peripheral profile, oxygen cathete 2 and exhaust are provided with the mask body 1
Pipe 3, the blast pipe 3 are interconnected with the viral sampling apparatus, and the viral sampling apparatus includes housing 4, the housing 4
Exhaust passage 5 is inside provided with, the blast pipe 3 connects with one end of exhaust passage 5, is located in the housing 4 in exhaust passage 5
Portion's opening position is provided with rotatable rotating disk 6, and the card of the rotating disk 6 is intercepted in the exhaust passage, the rotating disk upper measurement
Center of turntable rotational symmetry is provided with 4 through holes 7,4 through holes can be made successively from exhaust passage by rotating rotating disk
By being machined with 4 slots 8, the position of each slot 8 and each through hole 7 on the outer circumference surface of the rotating disk at passway
Position corresponds, and the slot 8 connects the madial wall of through hole 7 and the outer circumference surface of rotating disk；Also include that institute can be tightly inserted into
State the slotting disk 9 in slot 8, the end set of the slotting disk 9 there are a filter bores 10, and 10 set milipore filters at the filter bores, described
The edge shape for inserting the end of disk 9 is corresponding to the madial wall of through hole 7 so that inserts the edge of the end of disk 9 and the madial wall of the through hole
Between seal against each other.During sampling, slotting disk is inserted into slot, the gas of patient's exhalation can be entered in exhaust passage, then
It is enriched on milipore filter, makes next through hole is relative with exhaust passage mouth to connect taking out slot forward turn disk, so as to carry out down
Sampling once.The oxygen hood of the present utility model for facilitating gas virus sampling, realizes and enters while being cured by oxygen therapy to patient
The Concentration Sampling of row virus, and the design of viral sampling apparatus realizes the continuous beneficial effect uninterruptedly sampled.
