[0032] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Please refer to Figures 1 to 5As shown, this embodiment provides a novel high-flow oxygen inhalation tube, including a humidification mechanism, a heating box 2, and a corrugated oxygen inhalation tube 5. One end of the humidification mechanism is connected to an air inlet pipe 7 for delivering an oxygen source. The air inlet of the heating box 2 is connected to the air outlet of the humidification mechanism. An electric heating mesh 201 is detachably installed inside the heating box 2. The oxygen flowing into the heating box 2 is evenly heated after fully contacting the electric heating mesh 201. One end of the corrugated oxygen inhalation tube 5 is detachably connected to another end of the corrugated oxygen inhalation tube 5 via a connector. In this embodiment, the connector includes a connecting pipe 3 and a first locking nut quick connector 4. One end of the connecting pipe 3 is connected to the air outlet of the heating box 2, and the other end of the connecting pipe 3 has an internal thread on its inner wall. One end of the first locking nut quick connector 4 is threadedly fixedly installed at the end of the connecting pipe 3 away from the heating box 2. The other end of the corrugated oxygen inhalation tube 5 is connected to the other end of the first locking nut quick connector 4, and the other end of the corrugated oxygen inhalation tube 5 is connected to a nasal tube 6.

[0034] In this embodiment, the humidification mechanism includes a humidification box 1 and a venturi tube 13. The venturi tube 13 is fixedly connected inside the humidification box 1. A humidification tube 9 is installed on the top of the humidification box 1. The lower end of the humidification tube 9 is sealed and extends into the air inlet of the venturi tube 13. One end of the air inlet tube 7 is connected to the air inlet of the venturi tube 13. Several atomizing nozzles 902 are fixedly installed on the lower end of the humidification tube 9. The air outlet of the venturi tube 13 is connected to the air inlet of the heating box 2. A humidifying valve 901 is installed on the humidifying pipe 9, and an air valve 701 is installed on the air inlet pipe 7. By adopting the above technical solution, when oxygen humidification is required, the humidifying valve 901 is opened, and the humidifying mist is sprayed from the atomizing nozzle 902 to the air inlet end of the venturi tube 13. After preliminary mixing with the oxygen entering the venturi tube 13, they enter the throat of the venturi tube 13 for thorough mixing, and then are discharged from the air outlet of the venturi tube 13 into the heating box 2.

[0035] Specifically, in order to further improve the mixing effect of atomized water vapor and oxygen, the spraying direction of the atomizing nozzle 902 is directed towards the air inlet pipe 7. With this setting, the sprayed mist can be initially mixed with the oxygen entering the air inlet of the venturi tube 13.

[0036] In this embodiment, a control panel 10 is embedded in the humidifier box 1. A control circuit board is installed inside the control panel 10. A display screen 11 is fixedly installed on the surface of the control panel 10. The display screen 11 is electrically connected to the control circuit board. A function button 12 is installed on the control panel 10. The function button 12 is electrically connected to the control circuit board.

The temperature sensor 208 is electrically connected to the signal input terminal of the control circuit board. The electric heating grid 201 is controlled by the control circuit board. The heating temperature can be set by operating the function button 12.

[0037] By adopting the above technical solution, when oxygen needs to be heated, the heating temperature is set by operating the function button 12, and then the control circuit board controls the electric heating grid 201 to turn on. The electric heating grid 201 fully heats the oxygen entering the heating box 2. When the heated oxygen flows out of the outlet of the heating box 2, the temperature sensor 208 measures the temperature of the heated oxygen and transmits the measured temperature to the control circuit board, thereby realizing closed-loop control of the oxygen heating temperature.

The mounting plate 204 is fixedly installed in the mounting groove 203 by screws. The lower end of the screw passes through the mounting hole 205 and is threadedly fixed in the threaded groove 206. That is, the mounting plate 204 can be assembled and disassembled by removing and installing the screws, thereby facilitating the assembly and disassembly of the electric heating mesh 201.

[0040] Specifically, in order to ensure the sealing of the connection between the mounting plate 204 and the mounting groove 203, a fluororubber sealing ring is provided between the bottom of the mounting plate 204 and the top of the mounting groove 203.

[0041] Specifically, in order to facilitate the removal of the mounting plate 204 from the mounting groove 203, a notch 207 is provided at the bottom of the heating box 2, and the notch 207 is connected to the mounting groove 203.

[0042] In this embodiment, the end of the air inlet pipe 7 away from the humidification box 1 is threadedly fixed with a second lock-nut type quick connector 8 for connecting to the oxygen supply pipe of the oxygen tank. This setting facilitates the disassembly and assembly of the air inlet pipe 7 and the oxygen supply pipe.

[0043] In this embodiment, the end of the corrugated oxygen tubing 5 is connected via a connecting hose 507 to an end-tidal carbon dioxide detector 501 for monitoring the patient's end-tidal carbon dioxide content. This setup enables real-time monitoring of the patient's end-tidal carbon dioxide content, allowing for more accurate capture of the carbon dioxide concentration in the patient's exhaled gas and providing more reliable monitoring data. Medical staff can immediately understand whether the patient's respiratory function is normal and the effectiveness of oxygen therapy. By monitoring the end-tidal carbon dioxide content, medical staff can adjust the oxygen flow rate and treatment plan according to the patient's actual situation to achieve the best treatment effect. Continuous monitoring of end-tidal carbon dioxide content helps to detect respiratory dysfunction early and prevent possible complications, such as respiratory acidosis.

[0044] Among them, the end-tidal carbon dioxide detector 501 can be the CapStar-100 model end-tidal carbon dioxide monitor.

[0045] Among them, a carbon dioxide monitoring tube 504 is connected to the connecting hose 507. The carbon dioxide monitoring tube 504 is used to connect to a carbon dioxide monitor to monitor the carbon dioxide content of the breathing circuit.

[0046] The corrugated oxygen inhalation tube 5 has two straps 505 fixedly installed at the ends of the nasal tube 6 on both sides. Each strap 505 has a buckle 506 installed at the end away from the nasal tube 6. The buckle 506 includes a male buckle and a female buckle, which are used to stably fix the nasal tube 6 in the patient's nasal cavity.

[0047] In some embodiments, the upper end of the corrugated oxygen tubing 5 is connected to a nebulizer nozzle 502, and a nebulizer bottle 503 is connected to the nebulizer nozzle 502. The nebulizer bottle 503 is provided with a cap. When it is necessary to add nebulized medication to the corrugated oxygen tubing 5, the cap on the nebulizer bottle 503 is opened and the medication is placed into the nebulizer bottle 503.

[0048] To reduce the aerosol diffusion when the patient inhales the medication, a mask 14 is provided. The patient can wear the mask 14 during medication inhalation, which can reduce the aerosol diffusion. The mask 14 has a notch to allow the upper end of the corrugated oxygen tube 5 to be inserted and the lower end to be exited from the mask 14.
