Description

Technical Field

[0001] The invention relates to the technical field of oxygen concentrators, in particular to a pressurized oxygen concentrator dedicated for oxygen chamber inflation. Background Art

[0002] At present, commonly used oxygen concentrators are mainly used for direct oxygen therapy by users, and the oxygen output pressure is generally less than 60kpa. At present, oxygen concentrators are also used to provide oxygen in hyperbaric oxygen chambers. Due to the high pressure in the hyperbaric oxygen chamber, the oxygen output pressure of the oxygen concentrator dedicated to the oxygen chamber inflation needs to be designed to be increased. Due to the limitations of the current conventional PSA oxygen production system, the oxygen output pressure can be stabilized at around 120kpa, but when the oxygen output from the PSA oxygen concentrator passes through pipelines, valves and other transportation equipment, there will be a certain pressure loss. Even if the oxygen output pressure of the oxygen concentrator reaches 120kpa, the actual pressure after passing through the transportation pipeline may be lower than 100kpa. Therefore, when it is necessary to adapt to a hyperbaric oxygen chamber with a pressure of about 100kpa, due to factors such as system design, flow and stability issues, equipment limitations, and safety considerations, it cannot directly provide the required pressure and flow for the hyperbaric oxygen chamber to be stable.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1

[0023] A special pressurized oxygenator for oxygen chamber inflation, such as Figures 1 to 6As shown, it includes an oxygen-making air compressor 2, an oxygen-making solenoid valve 1, a molecular sieve tower 19, an oxygen storage tank 18, a pressure regulating valve 17, and a flow meter 16 which are sequentially connected to the oxygen-making air compressor 2. A high-pressure air intake solenoid valve 15 and a high-pressure air intake solenoid valve 24 are respectively connected to a boosting tank 1 8 and a boosting tank 2 9 between the air outlet of the oxygen-making air compressor 2. The boosting tank 1 8 and the boosting tank 2 9 adopt the same structure and material. The high-pressure air intake solenoid valve 15 and the high-pressure air intake solenoid valve 24 are respectively connected to the air outlet of the oxygen-making air compressor 2 and the oxygen-making solenoid valve 1 through the same three-way connection. An oxygen bag 1 24 and an oxygen bag 2 are respectively arranged inside the booster tank 1 8 and the booster tank 2 9. An extrusion space 1 23 is formed between the outer wall of the oxygen bag 1 24 and the inner wall of the booster tank 1 8, and an extrusion space 2 is formed between the outer wall of the oxygen bag 2 and the inner wall of the booster tank 2 9. The booster tank 1 8 and the booster tank 2 9 are both metal sealed tanks. The oxygen bag is made of silicone and has pressure bearing capacity, and the pressure bearing capacity is higher than 100kpa. It is flat in the natural state and bulges when the inside is inflated. The above uses the outlet pressure of the air compressor to pressurize the oxygen in the oxygen bag through the extrusion space in the booster tank, so that the oxygen in the oxygen bag can be smoothly filled into the hyperbaric oxygen chamber.

[0024] The outlet of flow meter 16 (oxygen outlet 11 of oxygen generator 2) is connected to oxygen bag 1 24 and oxygen bag 2 respectively through oxygen inlet solenoid valve 14 and oxygen inlet solenoid valve 2 15, and flow meter 2 10 is connected between oxygen inlet solenoid valve 14 and boosting tank 1 8 and between oxygen inlet solenoid valve 2 15 and boosting tank 2 9 respectively through oxygen outlet solenoid valve 1 12 and oxygen outlet solenoid valve 2 13. Specifically, flow meter 16 is connected to oxygen inlet solenoid valve 14 and oxygen inlet solenoid valve 2 15 respectively through a three-way connection, oxygen inlet solenoid valve 14 is connected to boosting tank 1 8 and oxygen outlet solenoid valve 1 12 respectively through a three-way connection, oxygen inlet solenoid valve 2 15 is connected to boosting tank 2 9 and oxygen outlet solenoid valve 2 13 respectively through a three-way connection, and oxygen outlet solenoid valve 12 and oxygen outlet solenoid valve 2 13 are connected to flow meter 2 10 through a three-way connection.

[0025] Flow meter 2 10 is connected to the oxygen outlet 11, and the air outlet of the oxygen compressor 2 is connected to the extrusion space 1 23 and the extrusion space 2 respectively. Exhaust pipes are connected to the booster tank 1 8 and the booster tank 2 9 respectively, and each exhaust pipe is connected to an air solenoid valve 1 6 and an air solenoid valve 2 7 respectively. On one side of the booster tank 1 8 and the booster tank 2 9, oxygen inlet and outlet 20, air connecting port 21 and high-pressure air inlet 22 are arranged from top to bottom in sequence, each oxygen inlet and outlet 20 is respectively connected with the corresponding oxygen bag 1 24 and oxygen bag 2, the air connecting port 21 and the high-pressure air inlet 22 are respectively connected with the corresponding extrusion space 1 23 and extrusion space 2, the oxygen inlet and outlet 20 of the booster tank 1 8 are respectively connected with one end of the oxygen inlet solenoid valve 1 14 and the oxygen outlet solenoid valve 1 12, the oxygen inlet and outlet 20 of the booster tank 2 9 are respectively connected with one end of the oxygen inlet solenoid valve 2 15 and the oxygen outlet solenoid valve 2 13, the air connecting port 21 is connected with the exhaust pipe, and is used to discharge the air extruded from the booster tank 1 8 and the booster tank 2 9 from the exhaust pipe, the high-pressure air inlet 22 of the booster tank 8 is connected with one end of the high-pressure air inlet solenoid valve 1 5, and the high-pressure air inlet 22 of the booster tank 2 9 is connected with one end of the high-pressure air inlet solenoid valve 2 4.

[0026] When the present invention is actually used, a preparation stage is designed. During the preparation stage, the oxygen production system starts to produce oxygen, the oxygen inlet solenoid valve 14, the air solenoid valve 16, the oxygen inlet solenoid valve 2 15, and the air solenoid valve 2 7 are opened, the oxygen outlet solenoid valve 12, the high-pressure air inlet solenoid valve 15, the oxygen outlet solenoid valve 2 13, and the high-pressure air inlet solenoid valve 2 4 are closed, and the flow meter 16 is adjusted to the maximum recommended flow of the oxygen production system to ensure that the oxygen concentration is qualified. The produced oxygen passes through the oxygen inlet solenoid valve 14 and the oxygen inlet solenoid valve 2 15 and enters the oxygen bag 1 24 and the oxygen bag 2 respectively, and the oxygen bag 1 24 and the oxygen bag 2 swell. When the oxygen bag 1 24 and the oxygen bag 2 are completely inflated and the pressure is increased to slightly lower than the oxygen outlet pressure, the oxygen intake of the oxygen bag 1 24 and the oxygen bag 2 gradually decreases, and the oxygen production system is in a low flow output state. At this time, the preparation stage is completed and the normal operation stage begins.

[0027] At the beginning of the normal operation stage, the oxygen outlet solenoid valve 12, the high-pressure air inlet solenoid valve 15, the oxygen inlet solenoid valve 215, and the air solenoid valve 27 are opened, the oxygen inlet solenoid valve 14, the air solenoid valve 16, the oxygen outlet solenoid valve 213, and the high-pressure air inlet solenoid valve 24 are closed, and the oxygen outlet end of the oxygen generator air compressor 2 continuously enters the oxygen bag 2 at a low flow rate through the flow meter 16 until the maximum oxygen capacity in the oxygen bag 2 is reached, and the flow meter 16 is closed, so that the oxygen produced by the oxygen production system is completely used for nitrogen exhaust, and the outlet of the oxygen generator air compressor 2 The gas end is connected with the extrusion space 23 in the booster tank 8. At this time, the pressure of the extrusion space 23 can reach more than 200Kpa. This pressure squeezes the oxygen bag 24 to reduce its volume until it stabilizes. At this time, the outlet pressure of the oxygen bag 24 also reaches more than 200Kpa. The high-pressure oxygen enters the flow meter 10 through the oxygen outlet solenoid valve 12. The flow meter 10 is set to be less than or equal to the maximum recommended flow of the system. The outlet end of the flow meter 10 is connected to the oxygen outlet 11 to continuously output oxygen to the oxygen chamber. The switching time is preset to ensure that the oxygen bag 24 is not completely emptied. At this time, the solenoid valve state is switched, that is, the oxygen outlet solenoid valve 12, the high-pressure air inlet solenoid valve 15 and the oxygen inlet solenoid valve 2 15, and the air solenoid valve 2 7 are closed, and the oxygen inlet solenoid valve 14, the air solenoid valve 16 and the oxygen outlet solenoid valve 2 13, and the high-pressure air inlet solenoid valve 2 4 are opened. At this time, the air outlet end of the oxygen compressor 2 is connected with the extrusion space 2 in the booster tank 2 9, and the pressure of the extrusion space 2 reaches more than 200Kpa, squeezing the oxygen bag 2 to reduce its volume until it is stable. At this time, the air outlet pressure of the oxygen bag 2 also reaches more than 200Kpa, and the high-pressure oxygen enters the flow meter 2 10 through the oxygen outlet solenoid valve 2 13. The flow meter 2 10 is set to be less than or equal to the maximum recommended flow of the system. The air outlet end of the flow meter 2 10 is connected to the oxygen outlet 11 to continuously output oxygen to the oxygen cabin. During this process, the oxygen produced by the oxygen production system enters the oxygen bag 24 through the oxygen inlet solenoid valve 14, and the oxygen bag 24 swells, squeezing the air in the booster tank 8 to be discharged from the exhaust pipe until it is full. When the preset switching time is reached, the solenoid valve state is switched to the previous state, and the previous cycle continues, thereby continuously outputting oxygen.

[0028] The oxygen chamber inflation-specific pressurizing oxygen machine of the present invention mainly realizes efficient pressurization and stable output of oxygen through the coordinated work of the oxygen-generating air compressor 2, the booster tank, and a series of solenoid valves and flow meters, thereby satisfying the requirement that the oxygen produced by the oxygen-generating system can be stably filled into the oxygen chamber at a higher pressure.

Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
