[0025] In view of the above problems, the ventilator pipeline provided by the embodiments of the present application can ensure the smooth breathing of the patient.

[0026] The technical scheme of the embodiments of the present application is described in detail below in combination with the drawings.

[0027] Figure 1 is a structural schematic diagram of the ventilator pipeline shown in the embodiments of the present application.

[0028] Referring to Figure 1 , the ventilator pipeline includes an air supply pipe 1, an exhaust pipe 2, a connecting pipe 3, a humidifier 4, an atomizer 5, a Y-shaped pipe 6, a patient end 7, a first water collecting cup 8 and a second water collecting cup 9. The connecting pipe 3 and the exhaust pipe 2 can be connected to a ventilator 100, and the ventilator 100 can provide oxygen for the patient through the air supply pipe 1 and the connecting pipe 3.

[0029] Referring to Figure 1, the air supply pipe 1 comprises an air supply main pipeline 11 and a first movable section 12, and the air exhaust pipe 2 comprises an air exhaust main pipeline 21 and a second movable section 22. The Y-shaped pipe 6 is communicated with one end of the air supply main pipeline 11, one end of the air exhaust main pipeline 21 and the patient end 7 respectively, and the patient can use the patient end 7 to breathe, the oxygen needed to be inhaled by the patient can reach the patient end 7 from the air supply pipe 1 through the Y-shaped pipe 6, and the gas exhaled by the patient can reach the air exhaust pipe 2 from the patient end 7 through the Y-shaped pipe 6.

[0030] Referring to Figure 1 , the other end of the air supply main pipeline 11 is communicated with the humidifier 4, one end of the connecting pipe 3 is communicated with the humidifier 4, and the humidifier 4 can humidify the oxygen sent to the patient from the breathing machine 100, so as to facilitate the patient to breathe. The atomizer 5 is communicated with the air supply main pipeline 11, the shell of the atomizer 5 is made of polyethylene material resistant to high temperature and high pressure, the atomizer 5 has an anticorrosive chip and a metal ceramic oscillation sheet inside, the atomizer 5 can be filled with drugs such as expectorant and asthma reliever, and the atomizer 5 can atomize the drugs to 4 microns of particles through the cooperation of the anticorrosive chip and the metal ceramic oscillation sheet, so as to more effectively reach the deep part of the airway of the patient.

[0031] Referring to Figure 1 , the first movable section 12 is communicated with the air supply main pipeline 11 and the first water collecting cup 8 respectively, and part of the water in the gas in the air supply main pipeline 11 can condense into water droplets at the first movable section 12, and then flow into the first water collecting cup 8. The first water collecting cup 8 can be deflected relative to the air supply main pipeline 11 through the first movable section 12, so that the first water collecting cup 8 is at the lowest position in the breathing machine pipeline. The second movable section 22 is communicated with the air exhaust main pipeline 21 and the second water collecting cup 9 respectively, and part of the water in the gas in the air exhaust main pipeline 21 can condense into water droplets at the second movable section 22, and then flow into the second water collecting cup 9. The second water collecting cup 9 is deflected relative to the air exhaust main pipeline 21 through the second movable section 22, so that the second water collecting cup 9 is at the lowest position in the breathing machine pipeline.

[0032] The first water collecting cup 8 is deflected relative to the air supply main pipeline 11 through the first movable section 12, and the second water collecting cup 9 can be deflected relative to the air exhaust main pipeline 21 through the second movable section 22, so that the first water collecting cup 8 and the second water collecting cup 9 can maintain the state that the openings of the first water collecting cup 8 and the second water collecting cup 9 are vertically upward due to the storage of liquid by relying on their own gravity when the patient uses the breathing machine pipeline, so as to avoid the liquid from entering the air supply pipe 1 or the air exhaust pipe 2 due to the inclination of the first water collecting cup 8 and the second water collecting cup 9, thereby ensuring the smooth breathing of the patient.

[0033] Referring to Figure 1In some embodiments, the first movable section 12 and the second movable section 22 are corrugated pipes. Since the corrugated pipes can be bent, the end of the first movable section 12 away from the air supply main pipe 11 can be bent downward to ensure that the top end of the first water collecting cup 8 is lower than the air supply main pipe 11, preventing the first water collecting cup 8 from tilting and causing the liquid in the first water collecting cup 8 to flow back to the air supply main pipe 11, avoiding the patient from accidentally inhaling the liquid flowing back in the first water collecting cup 8. The end of the second movable section 22 away from the air exhaust main pipe 21 can also be bent downward to ensure that the top end of the second water collecting cup 9 is lower than the air exhaust main pipe 21, preventing the second water collecting cup 9 from tilting and causing the liquid in the second water collecting cup 9 to flow back to the air exhaust main pipe 21, avoiding the patient from accidentally inhaling the liquid flowing back in the second water collecting cup 9.

[0034] Figure 2 FIG. 6 is another structural schematic diagram of the breathing machine pipeline according to an embodiment of the present application; Figure 3 FIG. 7 is a cross-sectional view of the first movable section according to an embodiment of the present application.

[0035] Referring to FIG. 1, Figure 2 and Figure 3 In some embodiments, the first movable section 12 comprises a first fixed pipe 121, a first ball 122 and a first rotating pipe 123. The first fixed pipe 121 is connected to the air supply main pipe 11 and the first ball 122 respectively. The first ball 122 is provided with a first inner cavity 124. The first ball 122 is provided with a plurality of first through holes 125. The first inner cavity 124 is connected to the first through holes 125 and the first fixed pipe 121 respectively. The first rotating pipe 123 is sleeved outside the first ball 122. The first rotating pipe 123 rotates around the first ball 122. The first through holes 125 are located in the first rotating pipe 123. The first rotating pipe 123 is connected to the first water collecting cup 8. The water droplets condensed at the junction of the air supply main pipe 11 and the first movable section 12 can flow into the first fixed pipe 121, then flow into the first inner cavity 124 from the first fixed pipe 121, and then flow into the first rotating pipe 123 from the first inner cavity 124 through the first through holes 125, and finally flow into the first water collecting cup 8. The first rotating pipe 123 can be bent downward relative to the first fixed pipe 121, so that the top end of the first water collecting cup 8 is lower than the air supply main pipe 11, so that the liquid in the first water collecting cup 8 cannot flow back to the air supply main pipe 11, ensuring that the patient will not inhale the liquid in the air supply main pipe 11. Preferably, the first movable section 12 further comprises a first sealing ring. The first sealing ring is sleeved outside the first ball 122. The first sealing ring is clamped between the first ball 122 and the first rotating pipe 123. The first sealing ring can increase the resistance of the first rotating pipe 123 relative to the first ball 122, but will not cause the first rotating pipe 123 to be unable to rotate relative to the first ball 122. The first sealing ring can ensure that the liquid in the first water collecting cup 8 will not evaporate and pass through the gap between the first rotating pipe 123 and the first ball 122 into the air, avoiding the surrounding environment of the patient from being polluted.

[0036] Referring to Figure 2 and Figure 3 In some embodiments, the second movable section 22 is structurally identical to the first movable section 12, and the second movable section 22 comprises a second fixed tube, a second ball, and a second rotating tube. The second fixed tube is connected to the exhaust main pipe 21 and the second ball respectively. The second ball has a second inner cavity therein. The second ball has a plurality of second through holes. The second inner cavity is connected to the second through holes and the second fixed tube respectively. The second rotating tube is sleeved outside the second ball. The second rotating tube rotates around the second ball. The second through holes are located in the second rotating tube. The second rotating tube is connected to the second water collecting cup 9. The water droplets condensed at the junction of the exhaust main pipe 21 and the second movable section 22 can flow into the second fixed tube, then flow into the second inner cavity from the second fixed tube, and then flow into the second rotating tube from the second inner cavity through the second through holes, and finally flow into the second water collecting cup 9. The second rotating tube can be bent downward relative to the second fixed tube, so that the top end of the second water collecting cup 9 is lower than the exhaust main pipe 21, so that the liquid in the second water collecting cup 9 cannot flow back into the exhaust main pipe 21, ensuring that the patient cannot inhale the liquid in the exhaust main pipe 21, and the liquid in the exhaust main pipe 21 cannot flow into the ventilator 100. Preferably, the second movable section 22 further comprises a second sealing ring. The second sealing ring is sleeved outside the second ball. The second sealing ring is clamped between the second ball and the second rotating tube. The second sealing ring can increase the resistance of the second rotating tube relative to the second ball, but will not cause the second rotating tube to be unable to rotate relative to the second ball. The second sealing ring can ensure that the liquid in the second water collecting cup 9 cannot enter the air through the gap between the second rotating tube and the second ball due to evaporation, avoiding pollution of the environment around the patient.

[0037] Referring to Figure 1 The middle part of the air supply main pipe 11 is provided with a Y-shaped air supply section 111. The first movable section 12 is connected to the Y-shaped air supply section 111 and the first water collecting cup 8 respectively. The first water collecting cup 8 is deflected relative to the Y-shaped air supply section 111 through the first movable section 12. The Y-shaped air supply section 111 can make the water droplets condensed at the junction of the air supply main pipe 11 and the first movable section 12 more easily flow downward and more easily pass through the first movable section 12 to enter the first water collecting cup 8. The middle part of the exhaust main pipe 21 is provided with a Y-shaped exhaust section 211. The second movable section 22 is connected to the Y-shaped exhaust section 211 and the second water collecting cup 9 respectively. The second water collecting cup 9 is deflected relative to the Y-shaped exhaust section 211 through the second movable section 22. The Y-shaped exhaust section 211 can make the water droplets condensed at the junction of the exhaust main pipe 21 and the second movable section 22 more easily flow downward and more easily pass through the second movable section 22 to enter the second water collecting cup 9.

[0038] In some embodiments, in order to facilitate medical staff to remove the first water collecting cup 8 and the second water collecting cup 9, the first movable section 12 is screwed to the first water collecting cup 8 at the end away from the gas delivery main pipeline 11, and the second movable section 22 is screwed to the second water collecting cup 9 at the end away from the gas exhaust main pipeline 21. Specifically, the top end of the first water collecting cup 8 and the second water collecting cup 9 is provided with external threads, and one end of the first movable section 12 and the second movable section 22 is provided with internal threads. The first water collecting cup 8 and the first movable section 12 are fixed together by cooperation of the internal threads and the external threads, and the second water collecting cup 9 and the second movable section 22 are fixed together by cooperation of the internal threads and the external threads. Medical staff can rotate the first water collecting cup 8 or the second water collecting cup 9 to remove the first water collecting cup 8 or the second water collecting cup 9, and pour away the liquid in the first water collecting cup 8 or the second water collecting cup 9.

[0039] In some embodiments, the breathing machine pipeline further comprises two counterweights connected to the bottom of the first water collecting cup 8 and the second water collecting cup 9 respectively. The bottom of the first water collecting cup 8 can be provided with a counterweight to make the opening of the first water collecting cup 8 always upward, so that the liquid in the first water collecting cup 8 cannot flow back to the gas delivery main pipeline 11, and the patient cannot inhale the liquid in the gas delivery main pipeline 11. The bottom of the second water collecting cup 9 can be provided with a counterweight to make the opening of the second water collecting cup 9 always upward, so that the liquid in the second water collecting cup 9 cannot flow back to the gas exhaust main pipeline 21, and the patient cannot inhale the liquid in the gas exhaust main pipeline 21, and the breathing machine 100 cannot be filled with liquid. Preferably, the counterweight is magnetically attached to the bottom surface of the first water collecting cup 8 or the second water collecting cup 9, the counterweight is made of a magnet, and the bottom of the first water collecting cup 8 and the bottom of the second water collecting cup 9 are fixed with an iron sheet. When there is not much liquid in the first water collecting cup 8 or the second water collecting cup 9, the counterweight can be attached to the bottom surface of the first water collecting cup 8 or the second water collecting cup 9 to make the opening of the first water collecting cup 8 or the second water collecting cup 9 always upward. When there is much liquid in the first water collecting cup 8 or the second water collecting cup 9, the counterweight can be removed to avoid excessive bending of the gas delivery main pipeline 11 and the gas exhaust main pipeline 21.
