[0024] Among them, the oxygen supply and delivery assembly includes an oxygenating cylinder 14, a hydraulic cylinder 15 and two air pumps 16. The open side of the oxygenating cylinder 14 is connected to the high-pressure oxygen chamber 2. The hydraulic cylinder 15 and the two air pumps 16 are fixedly installed on the support seat 1.

[0025] The hydraulic cylinder 15 is used to adjust the positions of the second piston 24 and the third piston 25, so that the oxygen introduced into the oxygenation cylinder 14 by the air pump 16 along the fixed cylinder 17 can be replenished into the interior of the hyperbaric oxygen chamber 2 and mixed with the original air in the hyperbaric oxygen chamber 2. Then, the same volume of air in the hyperbaric oxygen chamber 2 can be drawn back to ensure that the air pressure in the hyperbaric oxygen chamber 2 can remain stable after oxygen is replenished.
[0026] Working principle of this utility model:
[0027] Open the lock 4, first separate the chamber cover 3 from the hyperbaric oxygen chamber 2, then put the experimental animal into the interior of the hyperbaric oxygen chamber 2, cover the chamber cover 3, use the lock 4 to lock the hyperbaric oxygen chamber 2 and the chamber cover 3 again, operate the hydraulic cylinder 15 to pull the third piston 25 to move right for a distance, at this time the third piston 25 enters the interior of the hyperbaric oxygen chamber 2, the oxygenation cylinder 14 is connected to the hyperbaric oxygen chamber 2, the second piston 24 is still on the left side of the fixed cylinder 17, use the two air pumps 16 to fill the interior of the hyperbaric oxygen chamber 2 with nitrogen and oxygen respectively, observe the first barometer 13, and when the internal air pressure of the hyperbaric oxygen chamber 2 reaches the minimum air pressure value of the experiment, stop the inflation. The hydraulic cylinder 15 is controlled to pull the third piston 25 back to the inside of the oxygenation cylinder 14, and the activity state of the animal in the hyperbaric oxygen chamber 2 is observed. When the hyperbaric oxygen chamber 2 needs to be pressurized, the drive motor 7 can be controlled to drive the screw 6 to rotate forward, and the screw 6 pulls the first piston 10 to move toward the location of the connecting pipe 11 in a screw transmission manner. As the gas in the pressure regulating pipe 12 is squeezed into the hyperbaric oxygen chamber 2, the air pressure in the hyperbaric oxygen chamber 2 can be increased. By observing the first barometer 13, the hyperbaric oxygen chamber 2 can be pressurized to the air pressure value required for the experiment. In this way, the activity states of the experimental animals under different air pressures can be observed and recorded in turn;
[0028] Because the oxygen in the hyperbaric oxygen chamber 2 will be continuously consumed, it is necessary to add oxygen to the interior of the hyperbaric oxygen chamber 2 at regular intervals to change the concentration of oxygen in the hyperbaric oxygen chamber 2. In order to ensure that the air pressure of the hyperbaric oxygen chamber 2 remains unchanged after adding oxygen, it is necessary to start the air pump 16 to add oxygen to the interior of the fixed cylinder 17, and compare the second barometer 20 with the first barometer 13 until the values of the two are equal, that is, stop adding oxygen to the fixed cylinder 17. The fixed cylinder 17 is connected to the oxygenation cylinder 14, so that oxygen will enter the interior of the oxygenation cylinder 14, and the hydraulic cylinder 15 is controlled to contract to pull the second The piston 24 and the third piston 25 move right at the same time until all the oxygen in the oxygenation cylinder 14 is sent into the interior of the high-pressure oxygen chamber 2. At this time, the second piston 24 still remains in the oxygenation cylinder 14, and the third piston 25 enters the interior of the high-pressure oxygen chamber 2. After the gases in the high-pressure oxygen chamber 2 are mixed, the hydraulic cylinder 15 is controlled to pull the third piston 25 back to the interior of the oxygenation cylinder 14. At this time, part of the gas in the high-pressure oxygen chamber 2 will be brought back to the interior of the oxygenation cylinder 14, and the valve on the exhaust pipe 21 is opened to discharge the gas, and then the next oxygen replenishment to the high-pressure oxygen chamber 2 can be waited for.
