Gas is closed to enter back into air accumulator 11, air accumulator 11 has the function that to store mixed gas and buffers mixed gas, finally, mixing
In the oxygen face mask that gas enters in positive/negative-pressure nacelle from air accumulator 11 again or it is directly discharged into the cabin of positive/negative-pressure nacelle, from
And the patient aligned in negative pressure nacelle is treated, secondly, the helium and oxygen in gaseous mixture are can be appreciated that by gas sampling assembly
The mixed proportion of gas, and by adjusting the i.e. adjustable helium of the unlatching size of oxygen control valve 5 and oxygen control valve 5 and oxygen
Mixed proportion；Secondly, by controlling the unlatching size of air-supplying valve to can adjust the speed that mixed gas enters in positive/negative-pressure nacelle
And size, while the internal pressure of positive/negative-pressure nacelle can be controlled.And when needing to realize the function of hyperbaric oxygen chamber using the present invention, this
The left chamber 32 of invention and right chamber room 33 could act as hyperbaric oxygen chamber and used, it is of course also possible to make left chamber 32 as high
Oxygen cabin is pressed, right chamber room 33 is used as transition oxygen cabin；If it is used as hyperbaric oxygen chamber by the use of left chamber 32, it is only necessary to by left side
The left side overhead door 36 of the overhead door 36 of corridor pipe 35 and middle corridor pipe 35 is locked at closed state；And if made using right chamber room 33
For hyperbaric oxygen chamber, it is only necessary to which the right side overhead door 36 of the left side overhead door 36 of right side corridor pipe 35 and middle corridor pipe 35 is locked at into closed
State.And when needing to realize the function of negative-pressure oxygen cabin using the present invention, it is used as negative-pressure oxygen using the right chamber room 33 of the present invention
Cabin is used, will the right overhead door 36 of right side corridor pipe 35 and the left side overhead door 36 of middle corridor pipe 35 be locked at closed state i.e.
Can, secondly, according to different altitude environments, the pressure and oxygen parameter in right chamber room can be set, so as to be realized in right chamber room
The altitude environment of different height, then reach corresponding training or therapeutic purposes.Meanwhile the present invention can make left chamber 32 simultaneously
It is maintained at high pressure conditions, right chamber room 33 is kept to negative pressure state, so as to carries out medical treatment to two kinds of different patients.And pass through vacuum
Pump installation can carry out pumping decompression to left chamber and right chamber room, then make left chamber and right chamber room stable in suitable pressure value model
In enclosing, while also can be according to using needing right chamber room being maintained within range of negative pressure.
In summary, the invention is not restricted to above-mentioned embodiment.Those skilled in the art, do not departing from the present invention's
On the premise of spirit and scope, some change and modification can be done, all these changes all should fall into protection scope of the present invention.
