[0035] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0036] (1) By arranging a micro mixing chamber at the output end of the oxygen inlet pipe, a relatively thick oxygen stream is dispersed into multiple thin streams to form small bubbles. These small bubbles have a large specific surface area, which can significantly increase the contact area between oxygen and distilled water, thereby improving the humidifying effect. Specifically, the diversion channel design with a deflection angle of 30° - 60° enables the oxygen to form multiple thin streams when flowing through the diversion channel, further increasing the specific surface area of the bubbles. A magnetic stirring device is arranged inside the bottle body to create a rotating magnetic field, which is transmitted to the stirring rod through magnetic force to stir the distilled water to form a vortex. By adjusting the intensity of the vortex, the attraction of the vortex to the bubbles is controlled, so that the bubbles rotate on the outer circle of the vortex, increasing the contact time between the bubbles and the distilled water and further improving the humidifying effect. The magnetic stirring device with a motor speed of 50n - 100n can adjust the stirring intensity as needed to ensure sufficient humidification of oxygen. It significantly improves the humidifying effect of oxygen, ensures that the oxygen inhaled by the patient is more humid, and enhances the comfort and effect of oxygen therapy. The small bubbles rotate on the outer circle of the vortex, increasing the contact path between oxygen and distilled water while reducing the violent movement and rupture of the bubbles, avoiding the problem of uneven humidification caused by bubble rupture.

[0037] (2) Integrate a blood oxygen saturation detection device in the humidifying bottle system to monitor the patient's blood oxygen saturation in real time. The sensor unit contacts the patient's body tissue, the signal processing unit processes and analyzes the collected signals, and the data transmission unit transmits the processed data to the controller. The controller automatically adjusts the oxygen supply amount according to the detected blood oxygen saturation value. If the blood oxygen saturation is lower than the preset target value, the controller commands the solenoid valve to increase the oxygen flow rate and raise the oxygen concentration; if the blood oxygen saturation is higher than the target value, the controller commands the solenoid valve to reduce the oxygen flow rate and lower the oxygen concentration. The flow sensor and the pressure sensor are respectively arranged at the oxygen outlet of the humidifying bottle body to monitor the oxygen flow rate and pressure in real time and transmit the data to the controller. The controller further precisely adjusts the opening degree of the solenoid valve according to these data to ensure that the oxygen flow rate and pressure meet the treatment requirements. Automatically adjust the oxygen flow rate according to the blood oxygen saturation to ensure that the patient's blood oxygen saturation is always maintained within the optimal range, improving the safety and effectiveness of oxygen therapy. Monitor the blood oxygen saturation, oxygen flow rate, and pressure in real time to ensure the stability and accuracy of oxygen supply, reducing patient discomfort and safety hazards caused by insufficient or excessive oxygen supply.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific circumstances.

[0046] As Figure 1 、 Figure 2 shown, a device capable of automatically adjusting the oxygen humidification rate includes: a humidifying bottle main body 1, a mixing chamber main body, a magnetic stirring device, an adjusting mechanism, and a detecting mechanism. The mixing chamber main body is disposed inside the humidifying bottle main body 1 and is communicated with the air inlet pipe of the humidifying bottle main body 1; the magnetic stirring device is disposed at the lower end of the humidifying bottle main body 1; the adjusting mechanism is disposed at the upper end of the humidifying bottle main body 1 and is electrically connected to the magnetic stirring device; and the detecting mechanism is electrically connected to the adjusting mechanism.

[0047] The humidifying bottle main body 1 serves as the carrier of the entire device, with a mixing chamber main body disposed inside and communicated with an oxygen source through an air inlet pipe. The magnetic stirring device is located at the lower end of the humidifying bottle and is controlled by the adjusting mechanism to operate. The detecting mechanism then monitors relevant parameters in real time and feeds back information to the adjusting mechanism, improving the oxygen humidification effect and ensuring that the oxygen inhaled by the patient is more humid; it realizes automatically adjusting the oxygen supply amount according to the blood oxygen concentration, improving the safety and effectiveness of oxygen therapy.

[0048] As Figure 1 shown, the mixing chamber main body includes: a cylindrical shell 3 and a plurality of shunt channels. The cylindrical shell 3 is arranged at the lower end of the ventilation pipe 2 of the humidifying bottle main body 1, communicated with and fixedly connected to the ventilation pipe 2; and a plurality of shunt channels are respectively arranged on the circumferential side of the cylindrical shell 3 and are axially symmetrically arranged with the axis of the ventilation pipe 2 as the axis. The plurality of shunt channels are respectively deflected downward, and the deflection angle is 30°-60°.

[0049] The cylindrical shell 3 is installed at the lower end of the ventilation pipe 2 of the humidifying bottle main body 1, communicated with and fixedly connected to the ventilation pipe 2. A plurality of shunt channels are arranged on the circumferential side of the cylindrical shell 3, axially symmetrically arranged with the axis of the ventilation pipe 2 as the axis, and deflected downward by 30°-60°, so that when oxygen flows through the shunt channels, multiple thin streams are formed, and the oxygen is dispersed into small bubbles. The specific surface area of the bubbles is increased, the contact area between oxygen and distilled water is increased, and the contact path between oxygen and distilled water is further improved, thereby significantly improving the humidifying effect, making the oxygen inhaled by the patient more humid, and enhancing the comfort of oxygen therapy.

[0050] As Figure 1 shown, the magnetic stirring device includes: a bracket 4, a motor 5, a magnetic coupling, and a stirring rod 6. The bracket 4 is arranged at the bottom of the humidifying bottle main body 1 and fixedly connected to the humidifying bottle main body 1; the axis of the output shaft of the motor 5 coincides with the axis of the ventilation pipe 2 of the humidifying bottle main body 1, the motor 5 is arranged at the bottom of the humidifying bottle main body 1 and fixedly connected to the bracket 4, and the rotation speed of the motor 5 is 50n-100n. The magnetic coupling is arranged between the humidifying bottle main body 1 and the motor 5 and is respectively connected to the output shaft of the motor 5 and the humidifying bottle main body 1; and the stirring rod 6 is arranged in the humidifying bottle main body 1 and connected to the magnetic coupling.

[0051] When the motor 5 operates, power is transmitted to the stirring rod 6 through the magnetic coupling to stir the distilled water to form a vortex. By adjusting the rotation speed of the motor 5, the intensity of the vortex is controlled, so that the bubbles rotate on the outer circle of the vortex, further increasing the contact time between the bubbles and the distilled water, improving the humidifying effect, ensuring that the oxygen is fully humidified before being inhaled by the patient, and enhancing the oxygen therapy effect.

[0052] As Figure 1 shown, the magnetic coupling includes: an inner coupling 7 and an outer coupling 8. The inner coupling 7 is arranged on the output shaft of the motor 5 and coaxially and fixedly connected to the output shaft of the motor 5; and the outer coupling 8 is arranged at the bottom of the humidifying bottle main body 1, penetrates through the humidifying bottle main body 1, and is fixedly connected to the stirring rod 6.

[0053] When the motor 5 operates, the inner coupling 7 drives the outer coupling 8 to rotate, thereby driving the stirring rod 6 to stir the distilled water. The stable transmission of power is realized, ensuring that the stirring rod 6 can operate stably for a long time, improving the reliability and service life of the device, and reducing the maintenance cost at the same time.

[0054] As Figure 1 shown, the magnetic stirring device includes: a rubber sealing ring 9, which is arranged between the outer coupling 8 and the humidifying bottle body 1 and is respectively connected to the outer coupling 8 and the humidifying bottle body 1.

[0055] The rubber sealing ring 9 is installed between the outer coupling 8 and the humidifying bottle body 1, effectively preventing the leakage of distilled water, ensuring the stability of the internal environment of the humidifying bottle, and at the same time avoiding the corrosion and damage of the liquid to external circuit components, improving the safety and stability of the device.

[0056] The stirring rod 6 is made of medical-grade stainless steel and has a spiral shape.

[0057] Driven by the magnetic coupling, the stirring rod 6 rotates in the humidifying bottle, stirring the distilled water to form a vortex, making the bubbles rotate on the outer circle of the vortex, increasing the contact time between the bubbles and the distilled water. The medical-grade stainless steel material ensures the safety and corrosion resistance of the stirring rod 6, and the spiral design optimizes the stirring effect, enabling the bubbles to come into contact with the distilled water more fully, further improving the humidifying effect and providing higher-quality oxygen for patients.

[0058] As Figure 2 shown, the detection mechanism includes: a sensor unit, a signal processing unit, a data transmission unit, and a power management unit. The sensor unit is in contact with the patient's body tissue; the signal processing unit is electrically connected to the sensor unit; the data transmission unit is electrically connected to the signal processing unit; and the power management unit is electrically connected to the sensor unit, the signal processing unit, and the data processing unit respectively.

[0059] The sensor unit is in contact with the patient's body tissue and monitors parameters such as blood oxygen saturation in real time. The signal processing unit processes and analyzes the signals collected by the sensor unit. The data transmission unit transmits the processed data to the adjustment mechanism. The power management unit provides stable power for the sensor unit, the signal processing unit, and the data transmission unit. It realizes the real-time monitoring of the patient's blood oxygen saturation, provides an accurate basis for the automatic adjustment of the oxygen supply amount, improves the safety and effectiveness of oxygen therapy, and at the same time reduces the work burden of medical staff. The data transmission unit not only transmits the monitoring data to the controller, but also can transmit the data to the terminal devices of medical staff through a wireless communication module or a wired interface, such as the monitoring system of the nurse station or a mobile device, facilitating medical staff to observe and adjust the patient's oxygen therapy situation in real time.

[0060] The adjustment mechanism includes: a controller and a solenoid valve. The controller is disposed on the bracket 4 and fixedly connected to the bracket 4, and is electrically connected to the sensor unit, the signal processing unit, the data transmission unit, and the power management unit respectively; and the solenoid valve is disposed at the oxygen inlet of the humidifying bottle body 1, communicates with and is fixedly connected to the humidifying bottle body 1, and is electrically connected to the controller.

[0061] The controller controls the opening degree of the solenoid valve according to the blood oxygen saturation data fed back by the detection mechanism, and adjusts the oxygen supply amount. The automatic adjustment of the oxygen supply amount is realized, ensuring that the patient's blood oxygen saturation is always maintained within the optimal range, improving the safety and effectiveness of oxygen therapy, and at the same time improving the personalization and accuracy of oxygen therapy.

[0062] The adjustment mechanism includes: a flow sensor disposed at the oxygen outlet of the humidifying bottle body 1 and electrically connected to the controller.

[0063] The flow sensor is installed at the oxygen outlet of the humidifying bottle body 1, monitors the oxygen flow rate in real time, and transmits the data to the controller. The controller further accurately adjusts the opening degree of the solenoid valve according to the data of the flow sensor to ensure that the oxygen flow rate meets the requirements. The real-time monitoring and accurate control of the oxygen flow rate are realized, ensuring that the oxygen concentration inhaled by the patient meets the treatment requirements, improving the stability and reliability of oxygen therapy, and at the same time reducing the fluctuation of the oxygen therapy effect caused by unstable flow rate.

[0064] The adjustment mechanism includes: a pressure sensor disposed at the oxygen outlet of the humidifying bottle body 1 and electrically connected to the controller.

[0065] The pressure sensor is installed at the oxygen outlet of the humidifying bottle body 1, monitors the oxygen pressure in real time, and transmits the data to the controller. The controller further accurately adjusts the opening degree of the solenoid valve according to the data of the pressure sensor to ensure that the oxygen pressure meets the requirements. The real-time monitoring and accurate control of the oxygen pressure are realized, ensuring that the oxygen pressure inhaled by the patient meets the treatment requirements, improving the stability and safety of oxygen therapy, and at the same time reducing the fluctuation of the oxygen therapy effect and patient discomfort caused by unstable pressure.

[0066] When the present invention is used, Example 1: The deflection angle of the diversion channel is 30°, and the motor speed is 50n.

[0067] Example 2: The deflection angle of the diversion channel is 45°, and the motor speed is 50n.

[0068] Example 3: The deflection angle of the diversion channel is 60°, and the motor speed is 50n.

[0069] Example 4: The deflection angle of the diversion channel is 30°, and the motor speed is 75n.

[0070] Example 5: The deflection angle of the diversion channel is 30°, and the motor speed is 100n.

[0071] Exemplary experiment: Set different combinations of deflection angles and motor speeds respectively, and record the changes in the oxygen humidification effect under each combination.

[0072] Table 1 Table of changes in the oxygen humidification effect

[0073] Example Deflection angle of shunt channel / ° Motor speed / n Oxygen humidification rate / % 1 30 50 75 2 45 50 85 3 60 50 83 4 30 75 84 5 30 100 82

[0074] As can be seen from the above table, in Examples 1-3, as the deflection angle of the diversion channel increases from 30° to 60°, the oxygen humidification rate first increases and then decreases. When the diversion channel deflects downward by 30°-60°, multiple thin streams are formed when oxygen flows through the diversion channel, and they are dispersed into small bubbles. The specific surface area of these small bubbles is relatively large, which can significantly increase the contact area between oxygen and distilled water, thereby improving the humidification effect. The design of the deflection angle makes the bubbles form a longer contact path in the humidification bottle, further increasing the contact time between oxygen and distilled water and ensuring sufficient humidification of oxygen. Although a larger deflection angle can increase the contact area and contact time of the bubbles, an overly large deflection angle may cause too strong turbulence of the bubbles in the humidification bottle, instead reducing the residence time of the bubbles in the water and lowering the humidification effect. If the deflection angle of the diversion channel is too small, the specific surface area of the small bubbles formed when oxygen flows through the diversion channel will decrease. This will lead to a reduction in the contact area between oxygen and distilled water, thereby lowering the humidification effect. Too small a deflection angle will shorten the contact path of the bubbles in the humidification bottle and reduce the residence time of the bubbles in the water, further lowering the humidification effect. This may cause the oxygen inhaled by the patient to be insufficiently humidified, affecting the comfort of oxygen therapy. Due to the reduction in the bubble contact area and contact path, the humidification effect will decrease significantly. This not only affects the breathing comfort of the patient, but also may reduce the effect of oxygen therapy and increase the discomfort of the patient.

[0075] As can be seen from the above table, in Examples 1, 4, and 5, as the motor speed increases from 50n to 100n, the oxygen humidification rate first increases and then decreases. When the motor speed is 50n - 100n, power is transmitted to the stirring rod through the magnetic coupling to stir the distilled water to form a vortex. The bubbles rotate on the outer circle of the vortex, increasing the contact time with the distilled water and further improving the humidification effect. An appropriate motor speed can ensure that the bubbles are fully mixed in the vortex, so that the oxygen is fully humidified before being inhaled by the patient, improving the oxygen therapy effect. Although a higher motor speed can increase the contact time of the bubbles, an excessive speed may cause too strong turbulence of the bubbles in the vortex, reducing the residence time of the bubbles in the water and lowering the humidification effect. If the motor speed is too small, the rotation speed of the stirring rod will also slow down. This will cause the rotation speed of the bubbles on the outer circle of the vortex to slow down, reducing the contact time between the bubbles and the distilled water, thus lowering the humidification effect. If the motor speed is too small, the intensity of the vortex will be insufficient to effectively drive the bubbles to be fully mixed in the humidifying bottle. This may lead to unstable humidification effect, uneven distribution of bubbles in the water, and affect the humidification effect of oxygen. If the motor speed is too small, it may affect the stability and reliability of the magnetic coupling, resulting in uneven power transmission and unstable operation of the stirring rod. This will not only reduce the humidification effect but also increase the maintenance cost of the equipment.

[0076] Combined with the above experimental results, it can be seen that when the deflection angle of the shunt channel is 45° and the motor speed is 75n, it is most beneficial to the oxygen humidification effect.

[0077] When the present invention is in use, oxygen enters the mixing chamber main body in the humidifying bottle main body 1 through the air inlet pipe. The cylindrical shell 3 of the mixing chamber main body is installed at the lower end of the air pipe 2 of the humidifying bottle main body 1, communicated with and fixedly connected to the air pipe 2. Oxygen flows through several shunt channels in the cylindrical shell 3, causing the oxygen to form multiple thin streams when flowing through the shunt channels and dispersing into small bubbles. These small bubbles enter the distilled water in the humidifying bottle main body 1. The motor 5 of the magnetic stirring device operates, and power is transmitted to the stirring rod 6 through the magnetic coupling to stir the distilled water to form a vortex. The bubbles rotate on the outer circle of the vortex, increasing the contact time with the distilled water and further improving the humidification effect. The humidified oxygen is discharged through the oxygen outlet for the patient to inhale.

[0078] Meanwhile, the sensor unit of the detection mechanism contacts the patient's body tissue to monitor the patient's blood oxygen saturation in real time. The signal processing unit processes and analyzes the signals collected by the sensor unit, and the data transmission unit transmits the processed data to the controller of the adjustment mechanism. The controller determines whether the current blood oxygen saturation is lower than the target value according to the preset blood oxygen saturation target value. If the blood oxygen saturation is lower than the target value, the controller instructs the solenoid valve to increase the oxygen flow rate and raise the oxygen concentration; if the blood oxygen saturation is higher than the target value, the controller instructs the solenoid valve to decrease the oxygen flow rate and lower the oxygen concentration. The flow sensor and the pressure sensor are respectively installed at the oxygen outlet of the humidifier bottle body 1 to monitor the oxygen flow rate and pressure in real time and transmit the data to the controller. The controller further precisely adjusts the opening degree of the solenoid valve according to the data of the flow sensor and the pressure sensor to ensure that the oxygen flow rate and pressure meet the treatment requirements.

[0079] The display device is connected to the controller to display the current blood oxygen saturation value, oxygen flow rate and pressure in real time. The display device uses digital display or graphic display to intuitively display the changes of various parameters. The data transmission unit not only transmits the monitoring data to the controller, but also can transmit the data to the terminal devices of medical staff through a wireless communication module or a wired interface, such as the monitoring system of the nurse station or a mobile device. Medical staff can observe the patient's blood oxygen saturation, oxygen flow rate and pressure in real time, discover and handle abnormal situations in time, and improve the monitoring effect of oxygen therapy.

[0080] The rubber sealing ring 9 is installed between the outer coupling 8 and the humidifier bottle body 1, effectively preventing the leakage of distilled water, ensuring the stability of the internal environment of the humidifier bottle, and at the same time avoiding the corrosion and damage of liquid to external circuit components and other parts, improving the safety and stability of the device. The stirring rod 6 is made of medical-grade stainless steel, ensuring the safety and corrosion resistance of the stirring rod 6. The spiral design of the stirring rod 6 optimizes the stirring effect, enabling the bubbles to contact the distilled water more fully, further improving the humidification effect, and providing higher-quality oxygen for the patient.

[0081] Through the above coherent working process, the present invention realizes the efficient humidification of oxygen and the automatic adjustment of blood oxygen concentration, ensuring that the oxygen inhaled by the patient is more humid and the blood oxygen saturation is always maintained within the optimal range. The real-time monitoring and display functions facilitate medical staff to adjust and monitor the patient's oxygen therapy situation in time, improving the safety and effectiveness of oxygen therapy. These designs not only enhance the comfort and effect of oxygen therapy, but also reduce the work burden of medical staff, having important clinical application value.
