The air outlet connector 3.5 of the fan box 3 is fixedly communicated with one end of the first manual switch valve 4, and the other end of the first manual switch valve 4 is fixedly communicated with one end of the second pipeline 5. The other end of the second pipeline 5 is fixedly communicated with the air inlet connector 6.5 of the carbon dioxide absorption tank 6. The air outlet connector 6.6 of the carbon dioxide absorption tank 6 is fixedly communicated with one end of the third pipeline 7, and the other end of the third pipeline 7 is fixedly communicated with one end of the second manual switch valve 8. The other end of the second manual switch valve 8 is fixedly communicated with one end of the fourth pipeline 9, and the other end of the fourth pipeline 9 is fixedly communicated with the quick connector 10 on the air inlet of the portable pressure cabin.
[0014] As shown, Figure 2 The fan box 3 comprises a fan box body 3.1 and a fan box cover 3.2. The left and right ends of the fan box body 3.1 are respectively provided with an air inlet and an air outlet, and the air inlet and the air outlet are respectively fixedly connected with an air inlet connector 3.3 and an air outlet connector 3.4. The air inlet connector 3.3 and the air outlet connector 3.4 are quick plug connectors. The upper surface of the fan box body 3.1 is covered with the fan box cover 3.2. A fan is installed in the fan box 3. The fan is a diagonal flow blower and is fixedly arranged inside the fan box body 3.1. Its function is to suck the gas in the portable pressure cabin from the air outlet of the fan box into the air inlet of the fan box through centrifugal force, generate air flow through the rotation of the fan wheel, and then discharge from the air outlet of the fan box to drive the gas to flow to the air inlet of the portable pressure cabin, so as to re-enter the portable pressure cabin. The power of the fan is 13W, the diameter is not greater than 60mm, and the working voltage is 12V.
[0015] As shown, Figure 3 and Figure 4As shown, the carbon dioxide absorption tank 6 includes a tank body 6.1 for carrying the granular carbon dioxide absorbent, a first baffle, a second baffle 6.7, a pressure relief switch 6.2, a first tank cover 6.3 and a second tank cover 6.4. The tank body 6.1 is made of 316 stainless steel with a wall thickness of 5mm, and is processed by CNC into a cylindrical shape with a total length of 270mm and an outer diameter of 140mm. The two ends of the tank body 6.1 are fixedly connected with the first tank cover 6.3 and the second tank cover 6.4 respectively, the first tank cover 6.3 is provided with an air inlet, and the second tank cover 6.4 is provided with an air outlet, the air inlet and the air outlet are fixedly connected with an air inlet connector 6.5 and an air outlet connector 6.6 respectively, and the air inlet connector 6.5 and the air outlet connector 6.6 are quick plug connectors. The first baffle is fixedly connected to the inner wall of the first tank cover 6.3, and the second baffle 6.7 is fixedly connected to the inner wall of the second tank cover 6.4. The first baffle and the second baffle 6.7 are fixedly connected to the inner wall of the tank body 6.1. The tank body 6.1 can load the carbon dioxide absorbent with an inner diameter of 134mm, a length of 250mm and a weight of 3kg. When the first tank cover 6.3 and the second tank cover 6.4 cover the two ends of the tank body 6.1, the first baffle and the second baffle 6.7 are located at the ends of the tank body 6.1, and the first baffle and the second baffle 6.7 are porous structures with a pore size that is not passed by the granular carbon dioxide absorbent, such as the pore size of the first baffle and the second baffle 6.7 is smaller than the diameter of the carbon dioxide absorbent, and the second baffle 6.7 is provided with the pressure relief switch 6.2.
[0016] When the gas in the portable pressurized cabin flows through the porous structure of the first baffle under the action of the fan and flows into the tank body 6.1, the carbon dioxide absorbent in the tank body 6.1 absorbs the carbon dioxide in the gas at this time, and the absorbed gas flows back to the portable pressurized cabin after passing through the porous structure of the second baffle 6.7, so that the gas is recycled. After the absorption effect of the carbon dioxide absorbent reaches saturation, the staff closes the first manual switch valve 4 and the second manual switch valve 8, and then quickly disassembles and replaces the carbon dioxide absorbent in the tank body 6.1. The pore size of the first baffle and the second baffle 6.7 is smaller than the diameter of the granular carbon dioxide absorbent, which fixes the carbon dioxide absorbent in the tank body 6.1 and prevents the carbon dioxide absorbent from flowing to other parts to affect the normal work of the device. The second baffle 6.7 is provided with the pressure relief switch 6.2 for pressure relief operation of the gas in the carbon dioxide absorption tank 6.
[0017] The device is convenient, fast, practical and effective to remove carbon dioxide in the air in the portable pressure cabin, keeps the carbon dioxide concentration in the portable pressure cabin at a safe level during use, and ensures the safety of the patient. Meanwhile, the metal parts such as the first pipeline 2, the second pipeline 5, the third pipeline 7 and the fourth pipeline 9 are made of stainless steel, which has strong corrosion resistance. When in use, the airflow circulation generated by the brushless fan guides the gas in the portable pressure cabin to pass through the carbon dioxide absorption tank 6, thereby reducing the carbon dioxide concentration in the cabin. Therefore, the device avoids the problem of carbon dioxide poisoning caused by the patient during treatment, and solves the problem of inconvenient use of the existing carbon dioxide removal device during treatment.
