[0003] After searching, a respiratory humidifier disclosed in the patent with announcement number CN220656155U includes a water tank, an inner wall of the water tank is embedded with an electric heating plate, the output end of the electric heating plate is electrically connected to a temperature controller through a power cord, a sealing strip is fixedly installed at the edge of the top surface of the water tank, a baffle is fixedly installed on the top surface of the sealing strip, a servo motor is fixedly installed in the middle of the top surface of the baffle, a transmission rod is fixedly installed at the output end of the servo motor, and a stirring rod is fixedly installed at one end of the transmission rod.

[0004] Although the respiratory humidifier mentioned above can heat the water source inside the water tank through the electric heating plate and adjust it to a suitable temperature through the temperature controller, what is monitored in real time is the water temperature in the water tank, not the humidified oxygen temperature in the oxygen supply tube, resulting in inaccurate heating temperature control.

[0005] In view of the above problems, the utility model document proposes a respiratory tract humidifier. Utility Model Content

[0006] The utility model provides a respiratory tract humidifier, which solves the disadvantage in the prior art that what is monitored in real time is the water temperature in the water storage tank, not the humidified oxygen temperature in the oxygen delivery tube, resulting in inaccurate heating temperature control.

Then, connect one end of the oxygen supply tube to the output end of the humidifier tank through the first hollow plug, and the other end to the input end of the breathing mask through the second hollow plug. Find the power interface on the outer wall of the first hollow plug, connect one end of the plug-in wire to the power interface, and the other end to the built-in power supply of the humidifier body to ensure that the heating component can be powered normally;

[0019] Start the device: Press the power switch of the humidifier body to start the respiratory tract humidifier. At this time, the humidifier tank starts to work, evaporating water into humidified oxygen and transporting it to the breathing mask through the oxygen supply tube;

[0020] Adjust the heating temperature: observe the temperature display on the humidifier body, adjust the heating temperature of the heating component through the temperature control button, and adjust the temperature of the humidified oxygen to the appropriate range according to the patient's needs and the doctor's advice;

[0021] Monitor oxygen temperature: During the humidified oxygen delivery process, the heating component will continuously heat the humidified oxygen in the oxygen delivery tube and monitor the temperature of the humidified oxygen in real time through the temperature sensor. If the temperature exceeds the safe range, the device will sound an alarm to remind the user to adjust the heating temperature in time.

[0022] The utility model has the following beneficial effects:

[0023] The utility model evenly heats the humidified oxygen through the heating component to ensure that the oxygen inhaled by the patient is both moist and warm, avoiding the discomfort caused by inhaling too cold or too dry oxygen, and improving the patient's comfort. The temperature sensor monitors the temperature of the humidified oxygen in real time to ensure that the oxygen temperature is within a safe range, effectively avoiding potential risks to the patient caused by excessively high or low temperature.

[0024] The utility model can effectively prevent the humidification tank from accidentally falling off by arranging the arc-shaped inner buckle frame, thereby ensuring the stability and safety of the equipment during use; the sealing rings on the inner walls of the first hollow insert tube and the second hollow insert tube improve the sealing between the equipment and the humidification tank and the breathing mask, prevent oxygen leakage, and improve the overall performance of the equipment.

[0025] The utility model provides a respiratory tract humidifier with clear work flow and simple operation, which has the advantages of uniform heating, controllable temperature, safety and stability, and provides a strong guarantee for the oxygen supply treatment of patients.

[0036] A humidifier body 1, model PN-2000FB, is provided with a matching humidification tank 3 on the socket 2 on the top of the humidifier body 1. A certain amount of water is contained in the humidification tank 3. When oxygen passes through the humidification tank 3, it will contact with and absorb the water to achieve a humidification effect. An oxygen supply tube 4 is provided above the humidification tank 3. A first hollow insert 6 connected to the output end of the humidification tank 3 is fixedly provided at one end of the oxygen supply tube 4, and a second hollow insert 7 connected to the input end of the breathing mask is fixedly provided at the other end. In this way, the oxygen humidified by the humidification tank 3 can smoothly enter the breathing mask through the oxygen supply tube 4 to provide humidified oxygen to the patient;

[0037] The key point is that the respiratory tract humidifier is also provided with a heating component, which is arranged on the oxygen delivery tube 4. The main function of the heating component is to evenly heat the humidified oxygen in the oxygen delivery tube 4 to ensure that the oxygen maintains a certain temperature during the delivery process, and avoid the patient from feeling uncomfortable due to inhaling too cold oxygen. At the same time, the heating component also has the function of real-time monitoring the temperature of the humidified oxygen to ensure that the oxygen temperature is within a safe range. Specifically, the heating component includes a cable 5 wound and fixed on the outer wall of the oxygen delivery tube 4 and having a built-in heating wire. The built-in heating wire of the cable 5 extends to the inner wall of the oxygen delivery tube 4. The humidified oxygen in the oxygen delivery tube 4 is heated by the heating wire. On the inner wall of the second hollow insert 7, a temperature sensor 8 is provided for accurately monitoring the temperature of the humidified oxygen connected to the breathing mask to ensure that the temperature of the oxygen inhaled by the patient is appropriate.

[0038] For the convenience of power supply, a power interface 9 is provided on the outer wall of the first hollow insert 6, and the power interface 9 is electrically connected to the built-in power supply of the humidifier body 1 through a plug-in wire 10, so that the heating component and the temperature sensor 8 can be powered by the built-in power supply of the humidifier body 1, without the need for an external power supply, which is more convenient to use;

[0039] In order to facilitate the user to control the heating temperature, temperature control buttons 11 are provided on both sides of the temperature display screen of the humidifier body 1. The user can adjust the heating temperature of the heating component through the temperature control buttons 11 to make the temperature of the humidified oxygen reach the optimal state.
