The real-time collection device is composed of a back-mounted box and a breathing mask 35, an air outlet tube 32, an externally threaded tube 38, multiple thin tubes 36, a rubber figure-eight tube 37, an externally threaded tube 33, a rubber figure-eight tube 34, two rubber figure-eight tubes 39, an insulated tank 6, a gas-liquid enrichment component, a gas guiding component, and a flexible tube 30.

[0035] Setting up human-computer interaction devices to control the operation of real-time data collection devices is an existing technology and will not be elaborated here.

[0036] The real-time data collection device is used as follows:

[0037] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 ,Figure 10 and Figure 11 as shown in the figure;

[0038] Step one: two back straps 4 are fixedly installed on the front side of the device shell 1 in the back-mounted box, the user wears the back-mounted box through the two back straps 4, then takes the breathing mask 35, the outer side of the hose 30 is fixedly connected with the air outlet pipe 32, the bottom end of the outer thread pipe three 33 is fixedly connected, one end of the air guide pipe three 29 fixedly inserted on the device shell 1 is fixedly connected with the hose 30, one end of the outer side of the hose 30 is rotatably connected with the inner thread pipe two 31, the inner thread pipe two 31 is rotatably installed on the outer side of the outer thread pipe three 33, the device shell 1 and the breathing mask 35 are installed, the breathing mask 35 in contact with the mouth and nose of the patient in the real-time collection device can be quickly disassembled and replaced, and the safety of the real-time collection device is ensured.

[0039] The elastic rope 40 is installed on the breathing mask 35, the patient first covers the breathing mask 35 to the outer side of the mouth and nose, then sets the elastic rope 40 with elasticity to the outer side of the head, fixes the breathing mask 35, and the patient can perform gas-liquid collection work, and in this process, the position of the outer thread pipe three 33 is downward, the patient can complete the wearing of the real-time collection device, and the patient is limited in movement during the real-time process of the real-time collection device, and does not need to stay in place during the gas-liquid collection time, reducing the discomfort of the patient.

[0040] Step two:

[0041] The outer thread pipe one 7 is fixedly connected at the bottom end of the heat preservation tank 6, the outer thread pipe one 7 extends to the bottom of the back-mounted box, one end of the air guide pipe three 29 fixedly connected with the hose 30 is fixedly communicated with the top of the inner cavity of the heat preservation tank 6, the gas exhaled by the patient enters the inside of the heat preservation tank 6 through the hose 30 and the air guide pipe three 29, the heat conducting piece 9 in the gas-liquid enrichment assembly is fixedly installed on the top of the inner cavity of the heat preservation tank 6, a plurality of air holes 11 are formed on the top of the impeller 10 arranged in the heat conducting piece 9, the air guide pipe one 14 is fixedly communicated with the top of the heat preservation tank 6, the gas enters the inside of the heat conducting piece 9 through the channel between the heat preservation tank 6 and the heat conducting piece 9, and finally the gas enters the inside of the air guide pipe one 14 through the heat conducting piece 9. The direction changing box 15 in the air guide assembly is fixedly communicated with one end of the air guide pipe one 14, the one-way valve 22 is arranged on one side of the air guide pipe one 14, the bottom end of the air guide pipe two 23 fixedly connected with the outlet end of the one-way valve 22 is fixedly connected with the outer thread pipe two 24, and the bottom end of the outer thread pipe two 24 extends to the bottom of the back-mounted box.

[0042] When the real-time collection device is not used, the outer thread pipe two 24 and the outer thread pipe one 7 are threadedly installed with nuts on the outer sides, and the outer thread pipe two 24 and the outer thread pipe one 7 are blocked.

[0043] Step 3: Rotate and remove the nuts on the outside of the external threaded pipe 7 and external threaded pipe 24 to connect external threaded pipe 24 and external threaded pipe 7 to the outside. Pick up the sample container 28. The inlet end of the manual valve 25 at the top of the sample container 28 is fixedly connected to the internal threaded pipe 26. Rotate the sample container 28 to install the internal threaded pipe 26 to the outside of the external threaded pipe 7, so that the bottom end of the external threaded pipe 7 is blocked by the sample container 28. At this time, only the external threaded pipe 7 can vent air outward.

[0044] Step 4: The patient takes a deep breath. Multiple thin tubes 36 are fixedly connected to the outside of the breathing mask 35. Each thin tube 36 is fixedly connected to a rubber figure-eight tube 2 37. The open end of the rubber figure-eight tube 2 37 faces the inside of the breathing mask 35. The open end of the rubber figure-eight tube 1 34 fixedly connected inside the external threaded tube 33 faces the outside of the breathing mask 35. When the patient inhales from inside the breathing mask 35, the air pressure inside the breathing mask 35 decreases. At this time, the air pressure inside the breathing mask 35 is lower than the outside air pressure. Gas moves from the outside to the inside of the breathing mask 35. The direction of the outside gas movement and the direction of the airflow generated by the patient's inhalation are both the opening direction of the rubber figure-eight tube 2 37. The outside gas rushes through the multiple rubber figure-eight tubes 2 37 and enters the inside of the breathing mask 35, allowing the patient to inhale smoothly. When the air pressure inside the breathing mask 35 decreases, the rubber figure-eight tube 1 34 is kept closed by the inward contraction force, and the patient cannot inhale from inside the tubing 30.

[0045] When the patient exhales, the exhaled air acts on the outer wall of the rubber figure-eight tube 2 37. The rubber figure-eight tube 2 37 is kept closed by the inward contraction force. The exhaled air enters the rubber figure-eight tube 1 34, which opens the rubber figure-eight tube 1 34 and then enters the hose 30. Two rubber figure-eight tubes 39 are fixedly connected inside the external threaded tube 4 38 fixedly connected to the bottom of the outer side of the breathing mask 35. The open end of the rubber figure-eight tube 39 faces the inside of the breathing mask 35. The force required to open the rubber figure-eight tube 39 is greater than that of the rubber figure-eight tube 2 37, so the patient's normal deep breathing will not affect the state of the rubber figure-eight tubes 39. Therefore, by fixing multiple thin tubes 36, multiple rubber figure-eight tubes 2 37, external threaded tubes 33, and rubber figure-eight tubes 1 34 on the outside of the breathing mask 35, the inlet channel during the patient's inhalation and the exhaust channel during the patient's exhalation can be separated. This makes the air entering the hose 30 mainly the patient's exhaled air, increases the speed of gas-liquid collection, and reduces the time cost required for gas-liquid collection and sampling.

[0047] During the left and right movement of the block rod 17 controlled by the air pressure cylinder 21, the block rod 17 enters the inside of the air guide pipe 14 after moving a small distance to the right, and the gas in the inside of the back-hanging box 15 can only be discharged through the one-way valve 22 as the sliding piston 16 and the block rod 17 move to the right, and the gas pressure in the inside of the back-hanging box 15 decreases as the sliding piston 16 moves to the left because of the one-way conduction characteristic of the one-way valve 22, and the inside of the low-pressure back-hanging box 15 communicates with the inside of the air guide pipe 14 after the block rod 17 leaves the inside of the air guide pipe 14, and the exhaled gas in the inside of the air guide pipe 14, the heat preservation tank 6 and the hose 30 is extracted by the back-hanging box 15, so that the sliding piston 16 and the block rod 17 move left and right in the inside of the back-hanging box 15 when the air pressure cylinder 21 works, which accelerates the movement speed of the gas in the inside of the hose 30, the heat preservation tank 6, the heat conduction piece 9, the air guide pipe 14 and the air guide pipe 23, moves the exhaled gas of the patient from the real-time collection device, performs the air exchange work in the inside of the real-time collection device, and ensures the purity of the subsequent collection of the exhaled gas and liquid of the patient.

[0049] Step six: control the outside of the heat preservation tank 6 fixedly embedded multiple refrigeration piece 8 work, refrigeration piece 8 refrigeration end is set in the heat preservation tank 6, make the heat preservation tank 6 and the outer wall of the heat conducting piece 9 between the condensation channel, patient exhaled gas from the condensation channel inside movement into the heat conducting piece 9 inside process, gas condensation phenomenon, patient exhaled gas liquid precipitation, from the condensation channel inside through the gas into the heat conducting piece 9 inside, because the heat conducting piece 9 inside setting impeller 10 top fixedly installed transmission shaft 12, transmission shaft 12 top end through the air duct one 14 and with air duct one 14 rotationally connected, impeller 10 can in the heat conducting piece 9 inside rotation, the top of the back hanging type box cavity fixedly installed drive motor 13 output and transmission shaft 12 top fixed connection, control drive motor 13 work drive transmission shaft 12 and impeller 10 in the heat conducting piece 9 inside rotation, open multiple gas hole 11 impeller 10 rotation makes the heat conducting piece 9 inside gas centrifugal force, under the action of centrifugal force, gas in the heavier liquid and low temperature heat conducting piece 9 inner wall after the impact slide, heat preservation tank 6 inside condensation produced liquid and heat conducting piece 9 inside centrifugal separation liquid through the external thread pipe one 7 into the sample tank 28 inside, sample tank 28 storage liquid.

[0050] The sliding piston 16 and the plug rod 17 in the change direction box 15 move left and right and cooperate with the air duct one 14 to extract gas from the heat conducting piece 9, increase the flow speed of the gas entering the heat conducting piece 9, and the setting of the one-way valve 22 makes the gas enter and store in the air duct two 23 and the high-pressure tank 27 after the pressure in the change direction box 15 is increased, ensuring the amount of gas storage.
