Description

Technical Field

[0001] This invention relates to an oxygen supply device, and more particularly to a multi-parameter adaptive control high-flow humidified oxygen supply device, specifically a multi-parameter adaptive control high-flow humidified oxygen supply device characterized by stochastic resonance control. Background Technology

[0002] Currently, oxygen therapy is a routine treatment for various acute and chronic diseases, significantly improving hypoxia symptoms and promoting patient recovery. Clinically, nasal cannula oxygen therapy typically uses an open-type oxygen humidification bottle, which provides simple humidification to increase oxygen humidity, reducing irritation to the respiratory tract. However, this open-type humidification method cannot achieve sufficient humidity or effectively heat the oxygen. High-flow oxygen therapy has a certain therapeutic effect on patients with various respiratory failures, but its insufficient heating and humidification limit its clinical use via nasal cannulas.

[0003] In addition, most traditional oxygen therapy devices and high-flow oxygen inhalation devices are designed with fixed parameters for humidified oxygen supply, which cannot adaptively match the patient's actual physiological state, let alone adjust the oxygen supply flow and temperature based on the patient's blood oxygen saturation as the optimization target; the few oxygen supply devices with automatic parameter adjustment functions have low adaptability to complex clinical scenarios and are difficult to meet the needs of actual medical care. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-parameter adaptive control high-flow humidified oxygen supply device. It introduces a random resonance factor into the adaptive control and adjusts the oxygen supply flow and humidification heating with the patient's blood oxygen saturation as the optimization target. It can adapt to the complex clinical oxygen supply needs, has a high degree of intelligence, and is safe and reliable.

[0005] According to the technical solution provided by this invention, the multi-parameter adaptive control high-flow humidified oxygen supply device includes a humidification bottle for holding humidification liquid, an oxygen inlet pipe for introducing oxygen into the humidification bottle, and a humidified oxygen outlet pipe for outputting humidified oxygen from the humidification bottle; it also includes an oxygen flow valve for adjusting the flow rate of oxygen entering the humidification bottle through the oxygen inlet pipe, a humidification liquid heating device for heating the humidification liquid in the humidification bottle, a humidification temperature sensor for monitoring the temperature state inside the humidification bottle, a blood oxygen saturation sensor for collecting blood oxygen saturation, a transcutaneous carbon dioxide partial pressure sensor for collecting carbon dioxide partial pressure, and an oxygen supply controller for controlling the oxygen supply state; the oxygen supply controller is electrically connected to the oxygen flow valve, the humidification temperature sensor, the blood oxygen saturation sensor, and the transcutaneous carbon dioxide partial pressure sensor.

[0006] A target blood oxygen saturation value is preset in the oxygen supply controller. Based on the preset target blood oxygen saturation value, the current humidification temperature collected by the humidification temperature sensor, the current blood oxygen saturation value collected by the blood oxygen saturation sensor, and the current carbon dioxide partial pressure collected by the transcutaneous carbon dioxide partial pressure sensor, the oxygen supply controller can adjust the opening of the oxygen flow valve and the heating power of the humidification liquid heating device in real time. This ensures that when high-flow humidification oxygen supply is carried out using the humidified oxygen outlet pipe, the current blood oxygen saturation value collected by the blood oxygen saturation sensor matches the preset target blood oxygen saturation value.

[0007] After adjusting the oxygen flow valve opening on the oxygen supply controller, the following is obtained:

The second derivative of the transdermal carbon dioxide partial pressure value acquired by the transdermal carbon dioxide partial pressure sensor with respect to time t.

[0013] An inner cup body adapted to the humidification bottle is provided inside the humidification bottle. A vacuum isolation cavity is formed between the outer wall of the inner cup body and the inner wall of the humidification bottle. The inner cup body is adapted to and connected to the bottle mouth cap that seals the mouth of the humidification bottle. The inner cup body can hold humidification liquid. One end of the oxygen inlet pipe extends into the inner cup body, and the humidified oxygen outlet pipe is connected to the inner cup body.

[0014] A sound-absorbing coating is provided on the inner wall of the inner cup body, and a perforated plate is provided in the upper part of the inner cup body. The perforated plate is fixedly connected to the bottle mouth cap, and a number of air holes are provided on the perforated plate.

[0015] It also includes a humidifying liquid inlet mechanism that can add humidifying liquid into the inner cup and a humidifying liquid level gauge that can monitor the humidifying liquid level in the inner cup. Both the humidifying liquid inlet mechanism and the humidifying liquid level gauge are electrically connected to the oxygen supply controller. The oxygen supply controller obtains the humidifying liquid level through the humidifying liquid level gauge. When the obtained humidifying liquid level is lower than the humidifying liquid level threshold in the oxygen supply controller, the oxygen supply controller can output an indication message that humidifying liquid needs to be added, or the oxygen supply controller can add the required humidifying liquid into the inner cup through the humidifying liquid inlet mechanism.

[0016] The humidification liquid heating device includes several heating elements disposed at the bottom of the inner cup and a heating coil disposed at the bottom of the humidification bottle, wherein the heating coil is electrically connected to the oxygen supply controller.

[0017] The humidifying liquid inlet mechanism includes a humidifying liquid inlet pipe that can extend into the inner cup body; an ultrasonic vaporization device is provided at the end of the humidifying liquid inlet pipe located inside the inner cup body. The ultrasonic vaporization device is electrically connected to the oxygen supply controller. When the oxygen supply controller controls the ultrasonic vaporization device to work, the humidifying liquid in the inner cup body can be vaporized through the ultrasonic vaporization device to form an atomized environment in the upper part of the inner cup body.

[0018] It also includes an outlet insulation mechanism adapted to the humidified oxygen outlet pipe, which can keep the humidified oxygen output from the humidified oxygen outlet pipe warm.

[0019] One end of the humidified oxygen outlet pipe is adapted and connected to the inner cup body, and the other end of the humidified oxygen outlet pipe is connected and communicated with the oxygen delivery extension pipe. A silencer is installed on the humidified oxygen outlet pipe.

[0020] The outlet pipe insulation mechanism includes an insulation sleeve installed on the oxygen delivery extension pipe or a heating and insulation device installed on the oxygen delivery extension pipe. The heating and insulation device is electrically connected to the oxygen supply controller, and the working status of the heating and insulation device can be controlled by the oxygen supply controller.

[0021] The outlet insulation mechanism includes an outlet insulation pipe that can be connected and communicated with the humidified oxygen outlet pipe. An infrared LED heating unit and a temperature sensor of the temperature control pipeline that can detect the temperature of the humidified oxygen located in the outlet insulation pipe are installed inside the outlet insulation pipe. The temperature sensor of the temperature control pipeline and the infrared LED heating unit are both electrically connected to the oxygen supply controller.

[0022] A target temperature value for outlet air insulation is set in the oxygen supply controller. The oxygen supply controller compares the humidified outlet air temperature value detected by the temperature sensor in the temperature control pipeline with the target temperature value for outlet air insulation, and adjusts the working state of the infrared LED heating unit in the outlet air insulation pipe according to the comparison result, so that the humidified outlet air temperature value detected by the temperature sensor in the temperature control pipeline matches the target temperature value for outlet air insulation.

[0023] The infrared LED heating unit includes N sets of independent infrared LED heating elements, which are embedded in the air outlet insulation pipe. Each infrared LED heating element includes M infrared LED units.

[0024] When the oxygen supply controller adjusts the working status of the infrared LED heating unit, it can control the number of infrared LED units in each group of infrared LED heating units that are turned on. The number of infrared LED units in each group of infrared LED heating units that are turned on, O(n,t), is:

[0025]

[0026] in, This represents the operation of the nearest integer value less than or equal to t, where t is the current time, n is the sequence number of the infrared LED heating element (n∈[1,N]), M is the number of infrared LED units in each group of infrared LED heating elements, and T is the humidified exhaust temperature value detected by the temperature sensor in the temperature control pipeline. c Let W(t) be the target temperature for heat preservation at the outlet, and W(t) be the temperature control intensity. The temperature control intensity W(t) is: A is the overall gain, B is the damping coefficient, and D is the integral gain.

[0027] The advantages of this invention are: during oxygen supply, the opening of the oxygen flow valve and the heating power of the humidification liquid heating device can be adjusted in real time according to the preset target value of blood oxygen saturation, the current humidification temperature collected by the humidification temperature sensor, the current value of blood oxygen saturation collected by the blood oxygen saturation sensor, and the current value of carbon dioxide partial pressure collected by the transcutaneous carbon dioxide partial pressure sensor. This ensures that when high-flow humidification oxygen supply is performed using the humidified oxygen outlet pipe, the current value of blood oxygen saturation collected by the blood oxygen saturation sensor matches the preset target value of blood oxygen saturation, thereby adapting to complex clinical oxygen supply needs. It is highly intelligent and safe and reliable. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to specific accompanying drawings and embodiments.

[0033] like Figure 1 and Figure 2 As shown: To adapt to complex clinical oxygen supply needs and improve the level of intelligence, this invention includes a humidification bottle 4 for holding humidification fluid, an oxygen inlet pipe 1 for introducing oxygen into the humidification bottle 4, and a humidified oxygen outlet pipe 16 for outputting humidified oxygen from the humidification bottle 4; it also includes an oxygen flow valve 2 for adjusting the flow rate of oxygen entering the humidification bottle 4 through the oxygen inlet pipe 1, a humidification fluid heating device 28 for heating the humidification fluid in the humidification bottle 4, a humidification temperature sensor 29 for monitoring the temperature state inside the humidification bottle 4, a blood oxygen saturation sensor 30 for collecting blood oxygen saturation, a transcutaneous carbon dioxide partial pressure sensor 31 for collecting carbon dioxide partial pressure, and an oxygen supply controller 26 for controlling the oxygen supply status; the oxygen supply controller 26 is electrically connected to the oxygen flow valve 2, the humidification temperature sensor 29, the blood oxygen saturation sensor 30, and the transcutaneous carbon dioxide partial pressure sensor 31.

[0034] A target blood oxygen saturation value is preset in the oxygen supply controller 26. The oxygen supply controller 26 can adjust the opening of the oxygen flow valve 2 and the heating power of the humidification liquid heating device 28 in real time according to the preset target blood oxygen saturation value, the current humidification temperature collected by the humidification temperature sensor 29, the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30, and the current carbon dioxide partial pressure collected by the transcutaneous carbon dioxide partial pressure sensor 31. This ensures that when high-flow humidification oxygen supply is performed using the humidified oxygen outlet pipe 16, the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30 matches the preset target blood oxygen saturation value.

[0035] Specifically, the humidification bottle 4 needs to be made of materials that meet medical standards. The humidification bottle 4 is transparent and can be made of medical materials such as polypropylene; the specific material type can be selected according to needs. The humidification bottle 4 can hold humidification fluid, which can be in commonly used liquid forms, such as sterile distilled water or physiological saline, selected according to needs. Oxygen to be humidified is delivered into the humidification bottle 4 through the oxygen inlet pipe 1. The oxygen entering the humidification bottle 4 can fully contact the humidification fluid inside, achieving oxygen humidification. The humidified oxygen is discharged from the humidification bottle 4 through the humidified oxygen outlet pipe 16 to meet the oxygen supply needs of patients, etc. The specific oxygen supply method after humidification can be consistent with existing methods and is well known to those skilled in the art; it will not be elaborated here.

[0036] In this embodiment of the invention, one end of the oxygen inlet pipe 1 is connected to an oxygen supply device, and the other end of the oxygen inlet pipe 1 extends into the humidification bottle 4. Generally, the end of the oxygen inlet pipe 1 inside the humidification bottle 4 is close to the bottom of the humidification bottle 4, so as to place the end of the oxygen inlet pipe 1 within the humidification liquid as much as possible, thereby improving the efficiency of the humidification liquid in humidifying the oxygen. An oxygen flow valve 2 is adapted and connected to the oxygen inlet pipe 1. The oxygen flow valve 2 can be a solenoid valve or a manual valve. When it is a solenoid valve, the oxygen flow valve 2 is electrically connected to the oxygen supply controller 26, so that the opening degree of the oxygen flow valve 2 can be controlled by the oxygen supply controller 26. When the oxygen flow valve 2 is closed, oxygen cannot enter the humidification bottle 4 through the oxygen inlet pipe 1. The oxygen flow valve 2 can specifically be a commonly used solenoid valve, and the oxygen supply controller 26 can be a commonly used microprocessor. The specific form can be selected according to actual needs.

[0037] The humidifying liquid in the humidifying bottle 4 can be heated by the humidifying liquid heating device 28, and the temperature of the humidifying liquid in the humidifying bottle 4 can be monitored by the humidification temperature sensor 29. The humidification temperature sensor 29 can adopt existing commonly used temperature monitoring methods, and the specific temperature measurement method can be selected according to actual needs. These methods are well known to those skilled in the art and will not be described in detail here.

[0038] When humidified oxygen is supplied through the humidified oxygen outlet tube 16, the blood oxygen saturation sensor 30 can collect the oxygen saturation of the oxygen user, and simultaneously, the transcutaneous carbon dioxide partial pressure sensor 31 can collect the partial pressure of carbon dioxide in the exhaled gas during oxygen inhalation. The blood oxygen saturation sensor 30 and the transcutaneous carbon dioxide partial pressure sensor 31 can adopt existing commonly used forms, which are well known to those skilled in the art and will not be described in detail here. The specific process of collecting blood oxygen saturation through the blood oxygen saturation sensor 30 and the specific process of collecting carbon dioxide partial pressure using the transcutaneous carbon dioxide partial pressure sensor 31 are consistent with existing methods and are well known to those skilled in the art, and will not be described in detail here.

[0039] Those skilled in the art will know that when supplying oxygen to a user using the humidified oxygen outlet tube 16, the user's blood oxygen saturation is a crucial indicator. To adapt to complex oxygen supply needs, the oxygen supply controller 26 needs to set a target blood oxygen saturation value based on the user's specific condition. During oxygen supply, the oxygen supply controller 26 can simultaneously receive the current humidification temperature collected by the humidification temperature sensor 29, the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30, and the current carbon dioxide partial pressure value collected by the transcutaneous carbon dioxide partial pressure sensor 31. Based on the target blood oxygen saturation value, the current humidification temperature, the current blood oxygen saturation value, and the current carbon dioxide partial pressure value, the oxygen supply controller 26 can determine the flow rate of oxygen flowing into the humidification bottle 4 and the temperature of the humidification liquid in the humidification bottle 4. Thus, after adjustment, the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30 can match the preset target blood oxygen saturation value. Specifically, matching the current blood oxygen saturation value with the target blood oxygen saturation value means that the current blood oxygen saturation value is equal to the target blood oxygen saturation value, or the difference between the current blood oxygen saturation value and the target blood oxygen saturation value is stable within an allowable range. The specific choice can be made according to actual needs.

[0040] In this embodiment of the invention, when it is necessary to adjust the oxygen flow rate into the humidification bottle 4, this can be achieved by adjusting the opening of the oxygen flow valve 2. When the oxygen flow rate into the humidification bottle 4 decreases or increases, the flow rate of humidified oxygen output through the humidified oxygen outlet pipe 16 will also decrease or increase accordingly. The temperature of the humidified liquid in the humidification bottle 4 can be adjusted by adjusting the heating power of the humidification liquid heating device 28. After the heating power of the humidification liquid heating device 28 is adjusted, and the humidification liquid is heated using the humidification liquid heating device 28, the temperature of the humidified liquid in the humidification bottle 4 can be detected by the humidification temperature sensor 29.

[0041] In addition, the oxygen supply controller 26 can also be connected to an ambient temperature sensor to obtain the current ambient temperature. When controlling the heating of the humidification liquid heating device 28, the current ambient temperature can be referenced to further improve the comfort and reliability of high-flow oxygen inhalation.

[0042] Furthermore, after the oxygen supply controller 26 adjusts the opening of the oxygen flow valve 2, it obtains...

[0043]

[0044] Wherein, F(t) is the gas flow rate entering the humidification bottle 4 through the oxygen inlet pipe 1 after adjusting the opening of the oxygen flow valve 2, F0(t) is the gas flow rate entering the humidification bottle 4 through the oxygen inlet pipe 1 before adjusting the opening of the oxygen flow valve 2, S(t) is the current value of blood oxygen saturation collected by the blood oxygen saturation sensor 30, S0 is the target value of blood oxygen saturation, C(t) is the current value of transcutaneous carbon dioxide partial pressure collected by the transcutaneous carbon dioxide partial pressure sensor 31, t is the current time, N2(t) is the flow rate random resonance factor, N2(t)=d2G(0,1), G(0,1) is a normal distribution function with a mean of 0 and a variance of 1;

[0045] After the oxygen supply controller 26 adjusts the heating power of the humidification liquid heating device 28, the following is obtained:

[0046]

[0047] Wherein, P(t) is the heating power of the humidifying liquid heating device 28 after adjustment, P0 is the heating power of the humidifying liquid heating device 28 before adjustment, N1(t) is the heating random resonance factor, N1(t) = d1U(0,1), U(0,1) is the uniform distribution function of [0,1], a1, b1, c1, a2, b2, c2 are all proportional coefficients, t = qΔt, Δt is the sampling period, and q is a positive integer; The first derivative of the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30 with respect to time t. The second derivative of the transdermal carbon dioxide partial pressure value collected by the transdermal carbon dioxide partial pressure sensor 31 with respect to time t.

[0048] In this embodiment of the invention, the oxygen flow valve 2 can be a solenoid valve, and the oxygen supply controller 26 can adjust the opening degree of the oxygen flow valve 2. The proportionality coefficients a1, b1, c1, a2, b2, and c2 all have values ​​between -10 and 10, while d1 and d2 have values ​​between 0 and 3. The sampling period Δt is between 0.1 seconds and 10 seconds. Specifically, in the calculation, t = qΔt is used for discretization, where q is a positive integer. Depend on Calculated; Depend on Calculated.

[0049] In actual operation, the oxygen supply controller 26 calculates the opening degree of the oxygen flow valve 2 and the heating power of the humidification liquid heating device 28 in the above manner. After adjustment, it can make the current value of blood oxygen saturation monitored by the blood oxygen saturation sensor 30 close to the target value of blood oxygen saturation or match the target value of blood oxygen saturation.

[0050] In practice, during the oxygen supply process, the current blood oxygen saturation value collected by the blood oxygen saturation sensor 30 and the transcutaneous carbon dioxide partial pressure value collected by the transcutaneous carbon dioxide partial pressure sensor 31 will change. Therefore, during the process of adjusting the opening of the oxygen flow valve 2 and the humidification liquid heating power 28, the oxygen supply controller 26 needs to continuously adjust the power of the oxygen flow valve 2 and the humidification liquid heating power 28 accordingly so that the current blood oxygen saturation value during the oxygen supply process matches the target blood oxygen saturation value.

[0051] Furthermore, an inner cup 6 adapted to the humidification bottle 4 is provided inside the humidification bottle 4. A vacuum isolation cavity 5 is formed between the outer wall of the inner cup 6 and the inner wall of the humidification bottle 4. The inner cup 6 is adapted to and connected to the bottle mouth cap that seals the mouth of the humidification bottle 4. Humidification liquid can be contained through the inner cup 6. One end of the oxygen inlet pipe 1 extends into the inner cup 6, and the humidified oxygen outlet pipe 16 is connected to the inner cup 6.

[0052] A sound-absorbing coating 7 is provided on the inner wall of the inner cup body 6, and a perforated plate 15 is provided in the upper part of the inner cup body 6. The perforated plate 15 is fixedly connected to the bottle mouth cap, and a plurality of air holes are provided on the perforated plate 15.

[0053] In this embodiment of the invention, the inner cup 6 is generally made of a medical-grade transparent material. The inner cup 6 is smaller than the humidification bottle 4. The inner cup 6 is placed inside the humidification bottle 4, and after being placed inside the humidification bottle 4, it forms a vacuum isolation chamber 5. The vacuum isolation chamber 5 can provide heat insulation, improve the stability of the temperature of the humidification liquid during or after heating, and reduce heat loss and heating power consumption. In specific implementation, a bottle mouth cap is provided at the mouth of the humidification bottle 4. The bottle mouth cap can seal the mouth of the humidification bottle 4. After the inner cup 6 is placed inside the humidification bottle 4, the mouth of the inner cup 6 is connected to the bottle mouth cap, that is, the bottle mouth cap can also achieve sealing of the inner cup 6. This allows the oxygen entering the humidification bottle 4 to be humidified and discharged from the humidification bottle 4 through the humidified oxygen outlet pipe 16. After the inner cup 6 is installed, all the humidifying liquid will be stored in the inner cup 6. At this time, one end of the oxygen inlet pipe 1 extends into the inner cup 6, and the humidified oxygen outlet pipe 16 is connected to the inner cup 6.

[0054] The sound-absorbing coating 7 can adopt existing commonly used coating forms, and the specific coating material can be selected according to needs. Preferably, the sound-absorbing coating 7 covers the entire inner wall of the inner cup 6. The sound-absorbing coating 7 can convert sound energy into heat energy, and at the same time, it can reduce the noise generated when oxygen enters the humidification bottle 4. The perforated plate 15 is located inside the inner cup 6. The perforated plate 15 has multiple air holes and is fixed to the bottle cap. The perforated plate 15 can reduce the noise when oxygen is discharged from the inner cup 6 through the humidified oxygen outlet pipe 16.

[0055] Furthermore, it also includes an oxygen flow meter 3 adapted to the oxygen inlet pipe 1, an oxygen flow valve 2 is installed on the oxygen inlet pipe 1, the oxygen flow meter 3 is electrically connected to the oxygen supply controller 26, and the oxygen supply controller 26 can store or display the oxygen inlet flow rate counted by the oxygen flow meter 3.

[0056] In this embodiment of the invention, the oxygen flow meter 3 can be an electronic flow meter or a mechanical flow meter, whichever can be selected according to the actual situation. When an electronic flow meter is used, the oxygen flow meter 3 is electrically connected to the oxygen supply controller 26. The oxygen supply controller 26 can store or display the oxygen inlet flow rate counted by the oxygen flow meter 3, thereby effectively monitoring the oxygen inhalation process. The oxygen flow meter 3 and the oxygen inlet pipe 1 can adopt existing commonly used matching forms, which can be selected according to the specific form of the oxygen flow meter 3. The specific details are well known to those skilled in the art and will not be elaborated here.

[0057] Furthermore, it also includes a humidifying liquid inlet mechanism 27 that can add humidifying liquid into the inner cup 6 and a humidifying liquid level gauge 14 that can monitor the humidifying liquid level in the inner cup 6. Both the humidifying liquid inlet mechanism 27 and the humidifying liquid level gauge 14 are electrically connected to the oxygen supply controller 26. The oxygen supply controller 26 obtains the humidifying liquid level through the humidifying liquid level gauge 14. When the obtained humidifying liquid level is lower than the humidifying liquid level threshold in the oxygen supply controller 26, the oxygen supply controller 26 can output an indication message that humidifying liquid needs to be added, or the oxygen supply controller 26 can add the required humidifying liquid into the inner cup 6 through the humidifying liquid inlet mechanism 27.

[0058] In this embodiment of the invention, during the oxygen humidification process, oxygen can carry away some of the humidifying liquid in the inner cup 6. The humidifying liquid level gauge 30 can monitor the level of the humidifying liquid in the inner cup 6. The humidifying liquid level gauge 30 can be electronic or mechanical, depending on the requirements. When an electronic humidifying liquid level gauge 30 is used, it is electrically connected to the oxygen supply controller 26. In actual operation, a humidifying liquid level threshold can be set in the oxygen supply controller 26. The humidifying liquid level threshold can be selected as needed. Generally, if the level is below the threshold, oxygen cannot be humidified by the humidifying liquid. Therefore, the oxygen supply controller 26 can output an indication that humidifying liquid needs to be added, or the oxygen supply controller 26 can add the required humidifying liquid to the inner cup 6 through the humidifying liquid inlet mechanism 27. Generally, a scale line is set on the inner cup 6 or the humidification bottle 4, which can directly indicate the level of the humidifying liquid in the inner cup 6.

[0059] Generally, indicator lights, displays, etc. can be used to display the indication information that humidifier needs to be added. Of course, the oxygen supply controller 26 can also transmit the indication information that humidifier needs to be added through a wireless module. The wireless module can be a 5G module or the like. The specific choice can be made according to the needs, and will not be elaborated here. Figure 1 The image shows a mechanical humidification liquid level gauge, specifically including a spring force gauge 14 and a float 13. The float 13 is located inside the inner cup 6. By observing the floating state of the float 13 in the inner cup 6, the liquid level of the humidification liquid inside the inner cup 6 can be monitored.

[0060] Furthermore, the humidifying liquid inlet mechanism 27 includes a humidifying liquid inlet pipe 11 extending into the inner cup body 6; an ultrasonic vaporization device 12 is provided at the end of the humidifying liquid inlet pipe 11 located inside the inner cup body 6. The ultrasonic vaporization device 12 is electrically connected to the oxygen supply controller 26. When the oxygen supply controller 26 controls the ultrasonic vaporization device 12 to work, the humidifying liquid in the inner cup body 6 can be vaporized through the ultrasonic vaporization device 12, so as to form an atomized environment in the upper part of the inner cup body 6.

[0061] In this embodiment of the invention, the humidifying liquid inlet pipe 11 passes through the bottle cap and enters the inner cup 6. The end of the humidifying liquid inlet pipe 11 located outside the inner cup 6 forms a liquid inlet 10. An ultrasonic vaporization device 12 is installed at the end of the humidifying liquid inlet pipe 11 located inside the inner cup 6. The ultrasonic vaporization device 12 can specifically adopt commonly used ultrasonic vaporization methods, and the specific type can be selected as needed. This is well known to those skilled in the art and will not be described in detail here. The ultrasonic vaporization device 12 is electrically connected to the oxygen supply controller 26. When the oxygen supply controller 26 controls the ultrasonic vaporization device 12 to work, the humidifying liquid in the inner cup 6 can be vaporized through the ultrasonic vaporization device 12 to form an atomized environment in the upper part of the inner cup 6, thereby enhancing the humidification effect.

[0062] In practice, the humidifying liquid to be added is located inside a packaging bag. The humidifying liquid inside the packaging bag is compatible with the filling port 10, so the humidifying liquid inside the packaging bag is added to the inner cup 6 through the filling port 10 and the humidifying liquid inlet pipe 11. For humidifying liquid using a packaging bag, the humidifying liquid in the packaging bag can be replaced in one go. When adding humidifying liquid, the ultrasonic vaporization device 12 will not affect the humidifying liquid entering the inner cup 6 through the humidifying liquid inlet pipe 11. Of course, a filling solenoid valve can also be installed on the humidifying liquid inlet pipe 11. The oxygen supply controller 26 is electrically connected to the filling solenoid valve. The oxygen supply controller 26 can control the working state of the filling solenoid valve through the liquid level monitored by the humidifying liquid level gauge 30, that is, automatic liquid addition during the humidification process can be realized.

[0063] Furthermore, the humidification liquid heating device 28 includes a plurality of heating elements 8 disposed at the bottom of the inner cup body 6 and a heating coil 9 disposed at the bottom of the humidification bottle 4, wherein the heating coil 9 is electrically connected to the oxygen supply controller 26.

[0064] In this embodiment of the invention, the heating element 8 is adapted to the heating coil 9. Generally, the heating element 8 can be made of iron. To prevent oxidation, the surface of the heating element 8 has an anti-oxidation coating, which can be a polytetrafluoroethylene layer. The heating elements 8 are evenly distributed at the bottom of the inner cup 6 and cover the entire bottom of the inner cup 6. The heating coil 9 is located outside the humidification bottle 4 and is electrically connected to the oxygen supply controller 26. The oxygen supply controller 26 can control the heating power and other operating parameters of the heating coil 9 during heating, thereby controlling the heating process. Through the cooperation of the heating coil 9 and the heating element 8, the humidification liquid in the inner cup 6 can be effectively heated. Of course, the humidification liquid heating device 8 can also adopt other heating methods, which can be selected according to needs, as long as they can meet the heating requirements of the humidification liquid. These will not be elaborated here.

[0065] Furthermore, it also includes an outlet insulation mechanism adapted to the humidified oxygen outlet pipe 16, which can keep the humidified oxygen output from the humidified oxygen outlet pipe 16 warm.

[0066] In this embodiment of the invention, for long-distance delivery of humidified oxygen, an outlet heat preservation mechanism can be used to keep the oxygen warm, thereby preventing sudden temperature changes during delivery and improving the adaptability of oxygen users to humidified oxygen.

[0067] Figure 1 The diagram shows a schematic of the gas outlet insulation mechanism. Specifically, one end of the humidified oxygen outlet pipe 16 is adapted and connected to the inner cup body 6, and the other end of the humidified oxygen outlet pipe 16 is connected and communicated with the oxygen delivery extension pipe 22. A silencer 17 is provided on the humidified oxygen outlet pipe 16.

[0068] The outlet pipe insulation mechanism includes an insulation sleeve installed on the oxygen delivery extension pipe 22 or a heating and insulation device 19 installed on the oxygen delivery extension pipe 22. The heating and insulation device 19 is electrically connected to the oxygen supply controller 26, and the working state of the heating and insulation device 19 can be controlled by the oxygen supply controller 26.

[0069] In this embodiment of the invention, one end of the oxygen delivery extension tube 22 is connected and communicates with the humidified oxygen outlet tube 16, and the other end of the oxygen delivery extension tube 22 is connected to the flexible hose 24. An adjustable valve 18 is also provided on the humidified oxygen outlet tube 16. The oxygen delivery extension tube 22 can extend the length of the humidified oxygen outlet tube 16, and the oxygen delivery extension tube 22 can specifically adopt a commonly used form. The silencer 17 and the adjustable valve 18 can specifically adopt a commonly used form. The silencer 17 can block the propagation of sound, and the adjustable valve 18 can prevent throbbing. The adjustable valve 18 can be a manual or electronic valve, which can be selected according to needs. The oxygen delivery extension tube 22 is connected to the oxygen delivery extension tube 22 via a pipe connector 23. A nose clip 25 is provided on the flexible hose 24, allowing the flexible hose 24 to bend as needed. The nose clip 25 enables connection to the patient's nose, thus improving the convenience of oxygen inhalation.

[0070] In this embodiment of the invention, the heating and heat preservation device 19 is tubular, that is, it wraps around the oxygen delivery extension tube 22. The working state of the heating and heat preservation device 19 can be controlled by the oxygen supply controller 26. In specific implementations, a temperature sensor can also be set to monitor the temperature of the heating and heat preservation device 19 during heating, so as to avoid overheating. The heating and heat preservation device 19 can further keep the oxygen warm during the transmission process in the oxygen delivery extension tube 22. The oxygen delivery extension tube 22 has a water-absorbing coating inside to absorb a small amount of backflow condensate, preventing patients from inhaling condensate and causing discomfort. In addition, a heating control switch 20 is set on the oxygen delivery extension tube 22. The heating control switch 20 is electrically connected to the oxygen supply controller 26. The heating control switch 20 can turn on or off the heating and heat preservation device 19. The heating and heat preservation device 19 can adopt commonly used resistance heating or other heating methods. The specific method can be selected according to actual needs, which will not be elaborated here.

[0071] like Figure 3As shown, the outlet insulation mechanism can also be implemented in another form. Specifically, the outlet insulation mechanism includes an outlet insulation pipe 35 that can be connected and communicated with the humidified oxygen outlet pipe 16. An infrared LED heating unit and a temperature control pipeline temperature sensor 32 that can detect the temperature of the humidified oxygen located in the outlet insulation pipe 35 are installed in the outlet insulation pipe 35. The temperature control pipeline temperature sensor 32 and the infrared LED heating unit are both electrically connected to the oxygen supply controller 26.

[0072] A target temperature value for outlet gas insulation is set in the oxygen supply controller 26. The oxygen supply controller 26 compares the humidified outlet gas temperature value detected by the temperature sensor 32 of the temperature control pipeline with the target temperature value for outlet gas insulation, and adjusts the working state of the infrared LED heating unit in the outlet gas insulation pipe 35 according to the comparison result, so that the humidified outlet gas temperature value detected by the temperature sensor 32 of the temperature control pipeline matches the target temperature value for outlet gas insulation.

[0073] In this embodiment of the invention, the target temperature value for outlet air insulation is generally related to the temperature of the nasal cavity of the person receiving oxygen, and can be specifically selected and determined by medical personnel based on the actual situation of the person receiving oxygen. After the oxygen supply controller 26 adjusts the opening of the oxygen flow valve 2 and the power of the humidification liquid heating device 28, in order to reduce the influence of external temperature and other factors during the delivery of humidified oxygen, the outlet air insulation mechanism can further improve the reliability of oxygen supply, ensuring that the current blood oxygen saturation value during oxygen inhalation matches the target blood oxygen saturation value.

[0074] The outlet insulation pipe 35 can be connected and communicated with the humidified oxygen outlet pipe 16. Of course, the outlet insulation pipe 35 can also be part of the humidified oxygen outlet pipe 16. The specific connection and matching form can be selected according to the needs, which will not be elaborated here. An infrared LED heating unit is embedded in the outlet insulation pipe 35, and the temperature of the humidified oxygen flowing through the outlet insulation pipe 35 can be detected by the temperature sensor 32 of the temperature control pipeline.

[0075] The oxygen supply controller 26 is set with a target temperature value for outlet air insulation. The oxygen supply controller 26 directly compares the humidified outlet air temperature value detected by the temperature sensor 32 in the temperature control pipeline with the preset target temperature value for outlet air insulation, and controls the working state of the infrared LED heating unit according to the comparison result. Specifically, the working state of the infrared LED heating unit is controlled by reducing the heating power of the infrared LED heating unit, maintaining the heating power of the infrared LED heating unit, or increasing the heating power of the infrared LED heating unit. If the humidified outlet air temperature value is lower than the target temperature value for outlet air insulation, the oxygen supply controller 26 increases the heating power of the infrared LED heating unit, so that the humidified outlet air temperature value detected by the temperature sensor 32 in the temperature control pipeline matches the target temperature value for outlet air insulation.

[0076] Furthermore, the infrared LED heating unit includes N sets of independent infrared LED heating elements, which are embedded in the air outlet insulation pipe 35. Each infrared LED heating element includes M infrared LED units.

[0077] When the oxygen supply controller 26 adjusts the working state of the infrared LED heating unit, it can control the number of infrared LED units in each group of infrared LED heating units that are turned on. The number of infrared LED units in each group of infrared LED heating units that are turned on, O(n,t), is:

[0078]

[0079] in, The operation represents the operation of the nearest integer value less than or equal to t, where t is the current time, n is the sequence number of the infrared LED heating element (n∈[1,N]), M is the number of infrared LED units in each group of infrared LED heating elements, and T is the humidified exhaust temperature value detected by the temperature sensor 32 in the temperature control pipeline. c Let W(t) be the target temperature for heat preservation at the outlet, and W(t) be the temperature control intensity. The temperature control intensity W(t) is: A is the overall gain, B is the damping coefficient, and D is the integral gain.

[0080] In this embodiment of the invention, N groups of independent infrared LED heating elements 37 are distributed along the length of the exhaust insulation pipe 35. Generally, one group of infrared LED heating elements 37 can be arranged at intervals of 1cm to 5cm. The independence between the infrared LED heating elements 37 specifically means that the operation of each group of infrared LED heating elements 37 is independent, i.e., the operating state of one group of infrared LED heating elements 37 is not affected by the operating state of other groups of infrared LED heating elements 37. Generally, the number N of infrared LED heating elements 37 in the exhaust insulation pipe 35 can be set according to the length of the exhaust insulation pipe 35, and the number of infrared LED units in the infrared LED heating element can also be selected as needed, such as M being 5 to 10. Specifically, the overall gain A is typically 0.1 to 10; the damping coefficient B is typically 0.01 to 1; and the integral gain D is typically 0.001 to 0.1. For (TT) c The first derivative with respect to time t can be found in the calculation instructions above, which will not be repeated here.

[0081] Within the exhaust insulation pipe 35, N groups of infrared LED heating elements 37 are embedded. Each group of infrared LED heating elements 37 forms a ring within the exhaust insulation pipe 35, that is, it surrounds the axis of the exhaust insulation pipe 35. The N groups of infrared LED heating elements 37 can be evenly distributed within the exhaust insulation pipe 35. Specifically, regarding the sequence number n of the N groups of infrared LED heating elements 37, when supplying oxygen to an oxygen inhaler, the sequence number n decreases sequentially along the direction closest to the oxygen inhaler's nose. For example, within the exhaust insulation pipe 35, the infrared LED heating element 37 closest to the oxygen inhaler's nose has a sequence number n of 1, and the infrared LED heating element 37 furthest from the oxygen inhaler's nose has a sequence number n of N.

[0082] Specifically, when the oxygen supply controller 26 controls the working state of the infrared LED heating element 37, it specifically refers to controlling or selecting the number of infrared LED units in the infrared LED heating element 37 that are in the working state. When the infrared LED units are in the working state, they can emit infrared rays, which can be used to heat the humidified oxygen in the outlet insulation pipe 35.

[0083] In this embodiment of the invention, after setting the target temperature value for outlet gas insulation in the oxygen supply controller 26, the specific relationship between the humidified outlet gas temperature T collected by the temperature sensor 32 in the temperature control pipeline and the target temperature value for outlet gas insulation can be used to obtain the number of infrared LED units that are turned on in each group of infrared LED heating elements 37. When the oxygen supply controller 26 selects the number of working infrared LED units in each group of infrared LED heating elements 37, the humidified oxygen flowing through the outlet gas insulation pipe 35 can be kept warm through all the selected infrared LED units.

[0084] Furthermore, a condensate adsorption layer 36 is provided on the inner wall of the outlet heat insulation pipe 35, and a total reflection film 34 is provided on the outer wall of the outlet heat insulation pipe 35. The infrared wavelength emitted by the infrared LED unit when it is working is 1μm~100μm.

[0085] In this embodiment of the invention, the condensate adsorption layer 36 can be made of a water-absorbing resin material, possessing high water absorption capacity and excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even under pressure. The condensate adsorption layer 36 can adsorb the small amount of condensate generated in the exhaust insulation pipe 35 on-site. The total reflection film 34 can be a commonly used reflective film. Through the total reflection film 34, the infrared rays emitted by the infrared LED unit can be completely reflected, improving the efficiency and reliability of heating and insulation. In specific implementations, the wavelength of the infrared rays emitted by the infrared LED unit during operation is 1μm to 100μm.

[0086] In addition, the implementation also includes a temperature-controlled LED control circuit 33, which is electrically connected to the infrared LED heating unit embedded in the outlet insulation pipe 35. The temperature-controlled LED control circuit 33 is also electrically connected to the oxygen supply controller 26. The oxygen supply controller 26 can drive and control the operation of the infrared LED heating unit through the temperature-controlled LED control circuit 33. The temperature-controlled LED control circuit 33 can adopt a commonly used circuit form, which is well known to those skilled in the art and will not be described in detail here. Of course, it also includes an outlet insulation cable 38, which enables electrical connection between the outlet insulation cable 38 and the temperature-controlled LED control circuit 33 and the oxygen supply controller 26.
