Description

Technical Field

[0001] The present invention relates to the technical field of gas flow control of hydrogen production equipment, and specifically to a method for automatically controlling the gas flow output of hydrogen production equipment. Background Art

[0002] Hydrogen is increasingly widely used in modern industry. For example, it has broad application value in fields such as food, medicine, energy, and chemical industry. Hydrogen has the functions of antioxidation, anti-inflammation, anti-apoptosis, and cell repair. Especially selective antioxidation, the role of hydrogen in eliminating free radicals in medicine is increasingly recognized. Based on the above benefits of hydrogen, inhaling hydrogen is becoming more and more popular among people.

[0003] Currently, the common hydrogen production equipment is mainly based on the hydrogen production technology of electrolyzing water. Such hydrogen production equipment needs to be equipped with devices such as electrolytic cells and power supplies. There are two forms of electrolyzing water in the existing products on the market: one is to practice electrolyzing water in an electrolytic cell to produce a mixed gas of hydrogen and oxygen, and the other is to use a PEM electrolytic cell to separately produce hydrogen and oxygen. The output flow rates of hydrogen or hydrogen-oxygen mixed gas of these hydrogen production equipment are either constant values or adjusted by the user himself, choosing a certain fixed flow rate gear. However, most users cannot correctly select the flow rate of hydrogen or hydrogen-oxygen mixed gas they need during the use process, resulting in too high a flow rate of inhaled hydrogen or hydrogen-oxygen mixed gas, which will cause insufficient oxygen concentration in the inhaled oxygen, resulting in insufficient blood oxygen supply in the body, causing hypoxia in various organs of the body, thus bringing harm to the user. In view of this, we propose a method for automatically controlling the gas flow output of hydrogen production equipment. Summary of the Invention

[0004] In order to make up for the above deficiencies, the present invention provides a method for automatically controlling the gas flow output of hydrogen production equipment.

[0005] The technical solution of the present invention is as follows:

[0006] A method for automatically controlling the gas flow output of hydrogen production equipment includes the following steps:

[0007] Step 1: Clamp the blood oxygen probe on the patient's finger and detect the blood oxygen saturation using the non-invasive detection method;

[0008] Step 2: According to the detection result of the blood oxygen probe, perform the next operation process;

[0009] Step 3: If the blood oxygen saturation is less than 95%, reduce the hydrogen output and increase the oxygen output, and issue an alarm prompt;

[0010] Step 4: If the blood oxygen saturation is greater than or equal to 95%, record the blood oxygen saturation value N1 and start timing;

[0011] Step Five: After the timing time arrives, record the blood oxygen saturation value N2, and control the air flow according to the magnitudes of the previous and subsequent blood oxygen saturation values.

[0012] As a preferred technical solution of the present invention, the mechanism of the blood oxygen probe for detecting blood oxygen saturation lies in that different types of hemoglobin have different absorption rates for light of specific wavelengths. Here, the light of specific wavelengths uses red light and infrared light. The absorption rates of oxyhemoglobin and deoxyhemoglobin for red light and infrared light are different. Two light-emitting diodes in the blood oxygen probe emit visible red light with a wavelength of 660 nm and invisible infrared light with a wavelength between 920 and 950 nm respectively.

[0013] As a preferred technical solution of the present invention, the blood oxygen probe and the hydrogen production device are connected through a power cord. The hydrogen production device is internally provided with a main control board and a power board. The hydrogen production device is provided with an indicator light. The blood oxygen probe is connected to the main control board inside the hydrogen production device. The main control board is connected to the power board, and the main control board is connected to the indicator light. The main control board controls the flow rate of the electrolytic gas output by controlling the magnitude of the current generated by the power board during the electrolysis process. The greater the current, the greater the flow rates of the hydrogen and oxygen output. Conversely, the smaller the current, the smaller the flow rates.

[0014] As a preferred technical solution of the present invention, the specific operation of reducing the hydrogen output and increasing the oxygen output in Step Three is that the blood oxygen probe transmits the detected blood oxygen saturation information to the main control board inside the hydrogen production device. The main control board controls the current generated by the power board during the electrolysis process to decrease, thereby controlling the flow rate of the electrolytic hydrogen output, increasing the amount of oxygen inhaled by the human body, ensuring the normal oxygen content in the user's body, and ensuring that the user's blood oxygen saturation is greater than or equal to the preset value of 95%.

[0015] As a preferred technical solution of the present invention, the specific operation of controlling the air flow according to the magnitudes of the previous and subsequent blood oxygen saturation values in Step Five is to judge the difference between N2 and N1. If the difference is less than or equal to zero, maintain the existing gas flow. If the difference is greater than zero, send an instruction to the hydrogen production device. The main control board inside the hydrogen production device controls the current generated by the power board to decrease, reducing the hydrogen output flow rate by 100 ml / min.

[0016] As a preferred technical solution of the present invention, the alarm prompt in Step Three is indicated by an indicator light. When the blood oxygen saturation is less than 95%, the main control board controls the indicator light to turn on.

[0017] As a preferred technical solution of the present invention, the calculation formula for blood oxygen saturation is:

[0018]

[0019] C HbO2 refers to the concentration of oxyhemoglobin, C Hb refers to the concentration of deoxyhemoglobin.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The present invention detects the blood oxygen saturation of the human artery through a blood oxygen probe, transmits the detection signal to the main control board in the hydrogen production device through the blood oxygen probe, and controls the magnitude of the current generated by the power supply board during the electrolysis process through the main control board to control the flow rate of the electrolyzed gas output. The greater the current, the greater the flow rates of the hydrogen and oxygen output; conversely, the smaller. Thus, the amount of oxygen inhaled by the human body can be controlled to ensure that the oxygen content in the user's body is normal, and it is ensured that the blood oxygen saturation of the user is greater than or equal to the preset value of 95%. This method can form a closed-loop monitoring and dynamically adjust and control the user's blood oxygen saturation to be greater than or equal to 95%; and by setting an indicator light, it can play a prompting and alarming effect when the blood oxygen saturation is too low.

[0034] As a preferred technical solution of this embodiment, the specific operation of reducing the hydrogen output and increasing the oxygen output in Step 3 is that the blood oxygen probe transmits the detected blood oxygen saturation information to the main control board inside the hydrogen production device. The main control board controls the current generated by the power board during the electrolysis process to decrease, thereby controlling the flow rate of the electrolyzed hydrogen output, increasing the amount of oxygen inhaled by the human body, ensuring the normal oxygen content in the user's body, and ensuring that the user's blood oxygen saturation is greater than or equal to the preset value of 95%.

[0035] As a preferred technical solution of this embodiment, the specific operation of controlling the gas flow according to the magnitude of the blood oxygen saturation values before and after in Step 5 is to judge the difference between N2 and N1.

[0043]

[0044] where I is the intensity of the transmitted light, I0 is the intensity of the incident light, C a is the concentration of arterial blood, ε a is the total absorption coefficient of arterial blood, which is a constant, V a is the volume of arterial blood;

[0046] Then the above formula can be written as:

[0047]

[0048] The arterial volume change rate ΔV a / V a is proportional to the change rate of the light intensity ΔI / I passing through this volume. By converting this light intensity signal into an electrical signal, the change in the fingertip blood volume can be detected from the change rate of the light intensity.

[0049] It should be added that the preset value of blood oxygen saturation can be changed and set. It can be preset according to the physical needs of different patients.
