Conduit between 14 and narcotic bottle 16 is equipped with outgassing nonreturn valve 19, breather check valve 18 can oxygen unidirectionally enter ventilator
14, outgassing nonreturn valve 19 can oxygen ventilator 14 is unidirectionally discharged.
Flow control valve 20 is equipped at the medicine outlet of the narcotic bottle 16.
A switch valve 21 is equipped between the main oxygen source 12, spare source of oxygen 13 and first piston cylinder 1.
The lower end of the first piston 5 is connected with the first pull rod 22 stretched out outside first piston cylinder 1, second piston 8
Right end is connected with the second pull rod 23 stretched out outside second piston cylinder 7.
First piston 5 is pulled to first piston cylinder 1 by the first pull rod 22 first when specifically used by the utility model
Lower end, first piston 5 separate the second air inlet 3 with gas outlet 4, and the first pressure spring 6 is in compressive state, then open two oxygen
The switch valve 21 of gas source, the oxygen in main oxygen source 12 enter the first piston cylinder 1 of 5 top of first piston through the first air inlet 2
In interior and second piston cylinder 7 through 8 right side of the entrance of gas-guide tube 11 second piston, while making 1 top of first piston cylinder and second
7 right part of piston cylinder has pressure identical with main oxygen source 12, and the air pressure on the right side of second piston 8 pushes second piston 8 to overcome the
The pressure of two pressure springs 10 moves downward to protrude into the left end of piston rod 9 in first piston cylinder 1, then send out the first pull rod
22, first piston 5 is stopped to move upwards by the left end of piston rod 9, so that the first air inlet 2 is kept to connect with gas outlet 4,
Second air inlet 3 and gas outlet 4 separate；Oxygen in main oxygen source 12 enter in first piston cylinder 1 through the first air inlet 2 and from
Gas outlet 4 is discharged, and under the action of ventilator 14, the oxygen in first piston cylinder 1 successively passes through pressure reducing valve 17, breather check valve
Then 18, which enter ventilator 14, passes to anaesthetic mask 15 through outgassing nonreturn valve 19, when oxygen stream flows through narcotic bottle 16, anesthesia
Arcotic in medicine bottle 16 enters conduit and with oxygen is circulated to anaesthetic mask 15 and is inhaled by a patient is anaesthetized in vivo, passes through adjusting
The concentration of arcotic is adjusted in the flow control valve 20 in 16 exit of narcotic bottle.
As oxygen gradually uses up in main oxygen source 12, the air pressure in main oxygen source 12 is gradually reduced, and corresponding second
The pressure on 8 right side of piston is gradually reduced, and under the action of the second pressure spring 10, second piston 8 gradually moves right, piston rod 9
Left end is also gradually to movement, until piston rod 9 no longer stops first to live when first piston cylinder 1 is exited in the left end of piston rod 9 completely
Plug 5, under the action of the first pressure spring 6, the top of piston upwards to gas outlet 4, by the first air inlet 2 and gas outlet 4 every
It is disconnected, while the second air inlet 3 is connected with gas outlet 4, is switched to and is supplied oxygen by spare source of oxygen 13, anesthetist can draw from first
It is learnt in 22 retraction first piston cylinder 1 of bar and has been switched to spare source of oxygen 13, naturally it is also possible to which indicator light or buzzer etc. are set
Simple alarming device reminds anesthetist；The switch valve 21 on main oxygen source 12 is closed at this time, is removed main oxygen source 12 and is filled into it
Enter oxygen or replacement main oxygen source 12；After main oxygen source 12 is replaced, pulls downward on the first pull rod 22 and be pulled to down first piston 5
Then the switch valve 21 in main oxygen source 12 is opened at end, be switched to the oxygen supply of main oxygen source 12 again, while piston rod 9 is living by second
The pressure push-in 1 inner barrier first piston 5 of first piston cylinder on 8 right side of plug moves upwards, and can unclamp the first pull rod 22 at this time.
When main oxygen source 12 is broken down or results in the need for being switched to spare oxygen due to other non-air pressures deficiencies
When source 13 supplies oxygen, second piston 8 can be drawn to the right manually by the second pull rod 23, piston rod 9 is made to exit first piston cylinder completely
1, first piston 5 moves upwards under the action of the first pressure spring 6, is switched to spare source of oxygen 13 and supplies oxygen.
The utility model has the significant advantage that firstly, the utility model can be automatic in 12 oxygen deficiency of main oxygen source
