Description

Technical Field

[0001] This invention relates to the field of gas preparation and detection technology, and in particular to a method, system, computer equipment, and storage medium for the preparation and control of medical gases. Background Technology

[0002] Electronic atomizing devices are devices that atomize liquids (such as e-liquid) into vapor. They are widely used in various fields, such as medical and e-cigarette applications. Medical electronic atomizing devices simply perform a physical transformation of the liquid, converting the medium to be atomized from a liquid state into vapor with extremely small particle sizes. This vapor is then mixed with air for inhalation and has the function of separately producing hydrogen and oxygen. Furthermore, the method of using hydrogen and oxygen individually or in combination can be adjusted.

[0003] However, traditional medical electronic nebulizers often experience intermittent use during gas preparation, which can lead to excessive gas in the gas chamber, causing it to break the water vapor barrier. This results in the environment inside the gas chamber being directly connected to the outside, causing the prepared gas to come into direct contact with the outside air and affecting the humidity of the gas.

[0015] In one embodiment, after detecting whether the gas concentration compensation amount is greater than or equal to the second preset compensation amount, the method further includes: when the gas concentration compensation amount is less than the second preset compensation amount, sending a rapid gas signal to the medical gas power supply device to adjust the gas production mode of the medical gas generating device to a rapid gas production mode.

[0033] This invention relates to a method for regulating the preparation of medical gases. In one embodiment, the method includes acquiring the concentration of the stored gas in a medical gas generator; performing concentration difference compensation processing on the stored gas concentration and a preset gas concentration to obtain a concentration compensation amount; and sending a mode adjustment signal to a medical gas power supply device based on the concentration compensation amount to adjust the gas generation mode of the medical gas generator. By acquiring the stored gas concentration, it is convenient to determine the current gas concentration in the storage chamber of the medical gas generator. Performing concentration difference compensation processing on it with a preset gas concentration facilitates determining the difference between the gas concentration in the storage chamber of the medical gas generator and the standard concentration. Thus, based on the concentration difference, adjusting the mode adjustment signal input to the medical gas power supply device facilitates the regulation of the power supply to the medical gas generator, thereby facilitating the regulation of the gas generation mode of the medical gas generator and effectively reducing the probability of excessive gas in the storage chamber, thereby effectively reducing the probability of gas overflow.

[0034] Please see Figure 1 This is a flowchart of a medical gas preparation and control method according to an embodiment of the present invention. The medical gas preparation and control method includes some or all of the following steps.

[0035] S100: Obtain the concentration of the stored gas in the medical gas generator.

[0036] In this embodiment, the gas concentration in the storage chamber refers to the gas concentration in the storage chamber of the medical gas generator during the electrolysis gas production process. Specifically, the gas concentration corresponds to the current concentration of hydrogen or oxygen produced by the medical gas generator within the storage chamber, and also corresponds to the unit volume of gas in the storage chamber. The gas concentration is acquired through a gas concentration detector inside the medical gas generator, facilitating the acquisition of the current gas concentration in the storage chamber. This allows for the detection of the rate at which the gas is being pumped into the storage chamber, and consequently, the determination of the gas concentration changes at various times within the medical gas generator.

[0037] S200: Perform concentration difference compensation processing on the stored gas concentration and the preset gas concentration to obtain the gas concentration compensation amount.

[0038] In this embodiment, the gas concentration in the storage chamber refers to the gas concentration in the storage chamber of the medical gas generator during the electrolysis gas production process. Specifically, the gas concentration corresponds to the current concentration of hydrogen or oxygen produced by the medical gas generator in the storage chamber, and also corresponds to the unit volume of gas in the storage chamber. The preset attitude parameter is the normal gas concentration of the medical gas generator, corresponding to the gas mass of the medical gas generator in a standard storage chamber volume, i.e., the maximum gas concentration in the standard storage chamber. Performing concentration difference compensation processing on the gas concentration in the storage chamber and the preset attitude parameter compares the current gas storage condition of the medical gas generator with the standard gas storage condition. Based on this gas concentration difference, it is easy to obtain the difference in the current gas concentration of the medical gas generator, thereby facilitating the determination of whether the current gas concentration of the medical gas generator is excessive, and further facilitating the determination of the degree of difference between the current gas concentration and the standard gas concentration, i.e., the gas concentration compensation amount. In this way, based on the difference in gas concentration compensation, it is easy to determine whether the gas storage chamber of the medical gas generator is filled with excessive gas, thereby facilitating the control of the gas generation mode of the medical gas generator and the subsequent regulation of the gas production rate of the medical gas generator.

[0039] S300: Send a mode adjustment signal to the medical gas power supply device according to the gas concentration compensation amount to adjust the gas production mode of the medical gas generating device.

[0040] In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration and the standard gas storage concentration of the medical gas generator. In other words, the gas concentration compensation amount is a reference value for detecting whether the current gas volume in the gas storage chamber of the medical gas generator is normal. The magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generator. Based on the value of the gas concentration compensation amount, it can be determined whether the current gas production rate of the medical gas generator is normal or abnormal. Thus, after determining the gas concentration compensation amount, it is convenient to control the output current of the gas generating power supply device, that is, to control the electrolysis current of the medical gas generator, and to regulate the current loaded for electrolyzing hydrogen and oxygen in the medical gas generator, so as to ultimately adjust the gas output flow rate of the medical gas generator, and thus facilitate the adjustment of the current gas production mode of the medical gas generator.

[0041] In the above embodiments, by collecting the gas concentration data, the current gas concentration in the gas storage chamber of the medical gas generator can be determined. Concentration difference compensation processing is then performed between this concentration and a preset gas concentration to accurately determine the difference between the gas concentration in the storage chamber and the standard concentration. Subsequently, based on this concentration difference, the power supply from the medical gas power supply device to the medical gas generator can be adjusted by modifying the mode adjustment signal input to the medical gas power supply device. This facilitates the control of the gas generation mode of the medical gas generator, effectively reducing the probability of excessive gas in the storage chamber and thus effectively reducing the probability of gas overflow.

[0042] In one embodiment, the step of performing concentration difference compensation processing on the stored gas concentration and the preset gas concentration to obtain a gas concentration compensation amount includes: performing a gas concentration difference operation on the stored gas concentration and the preset gas concentration to obtain a gas concentration difference component; and performing a gas concentration weighting operation on the gas concentration difference component to obtain the gas concentration compensation amount. In this embodiment, the stored gas concentration is the gas concentration in the gas storage chamber corresponding to the electrolytic gas generation process of the medical gas generator, that is, the stored gas concentration corresponds to the current concentration of hydrogen or oxygen produced by the medical gas generator in the gas storage chamber, and also corresponds to the unit volume of gas in the gas storage chamber of the medical gas generator. The preset attitude parameter is the normal stored gas concentration of the medical gas generator, that is, the preset attitude parameter corresponds to the gas mass of the medical gas generator under the standard gas storage chamber volume, that is, the maximum gas concentration in the standard gas storage chamber. Since both the stored gas concentration and the preset gas concentration are obtained from the medical gas generator, the gas concentration difference operation is performed on the stored gas concentration and the preset gas concentration. First, errors in the stored gas concentration and the preset gas concentration are mutually canceled to improve the comparison accuracy between them, making the gas concentration difference component more accurate as a representation of the difference between the stored gas concentration and the preset gas concentration. Then, a gas concentration weighting operation is performed on the gas concentration difference component. This involves weighting the gas concentration difference component. Because the gas produced by the medical gas generator is hydrogen and oxygen generated by electrolysis, the output of hydrogen and oxygen produced by the medical gas generator varies per unit time, resulting in different rates at which the two gas storage chambers of the medical gas generator fill with gas. Therefore, a weighted average of the different stored gases is needed to make the obtained gas concentration compensation amount more accurate.

[0043] In one embodiment, the step of sending a model adjustment signal to the medical gas power supply device according to the gas concentration compensation amount to adjust the gas production mode of the medical gas generator includes: detecting whether the gas concentration compensation amount matches a first preset compensation amount; and when the gas concentration compensation amount matches the first preset compensation amount, sending a first gas model signal to the medical gas power supply device. In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration and the standard gas storage concentration of the medical gas generator. That is, the gas concentration compensation amount is a reference value for detecting whether the gas volume in the current gas storage chamber of the medical gas generator is normal, and the magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generator. The first preset compensation amount is a standard gas concentration compensation amount for the medical gas generator, that is, the first preset compensation amount is the gas concentration difference corresponding to a specific gas storage concentration of the medical gas generator, or the first preset compensation amount is the concentration difference value under a specified gas storage concentration of the medical gas generator. The matching of the gas concentration compensation amount with the first preset compensation amount indicates that the current gas concentration of the medical gas generator is the same as the specified gas concentration, meaning that the current gas concentration of the medical gas generator is equal to the specific gas concentration, and that the current gas concentration in the gas storage chamber of the medical gas generator is within the specified gas concentration range. At this time, a first gas control signal is sent to the medical gas power supply device to control the operating state of the medical gas generator in the corresponding gas generation mode.

[0044] Further, the step of sending a first gas model signal to the medical gas power supply device when the gas concentration compensation amount matches the first preset compensation amount includes: when the gas concentration compensation amount is greater than or equal to the first preset compensation amount, sending a gas stop signal to the medical gas power supply device to adjust the gas production mode of the medical gas generator to a gas stop mode. In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration and the standard gas storage concentration of the medical gas generator. That is, the gas concentration compensation amount is a reference value for detecting whether the gas quantity in the current gas storage chamber of the medical gas generator is normal, and the magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generator. The first preset compensation amount is a standard gas concentration compensation amount for the medical gas generator, that is, the first preset compensation amount is the gas concentration difference corresponding to a specific gas storage concentration of the medical gas generator, or the first preset compensation amount is the concentration difference value under a specified gas storage concentration of the medical gas generator. If the gas concentration compensation amount is greater than or equal to the first preset compensation amount, it indicates that the current gas concentration of the medical gas generator is greater than the specified gas concentration, meaning that the current gas concentration of the medical gas generator exceeds the safe gas concentration, and that the current gas concentration in the gas storage chamber of the medical gas generator is within the excessively concentrated range. In this case, a gas stop signal is sent to the medical gas power supply device to adjust the operating state of the medical gas generator to a stop-gas-generating mode, thus stopping the medical gas generator from continuing to generate gas.

[0045] In another embodiment, after detecting whether the gas concentration compensation amount matches the first preset compensation amount, the method further includes: when the gas concentration compensation amount does not match the first preset compensation amount, sending a second gas model signal to the medical gas power supply device. In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration and the standard gas storage concentration of the medical gas generator. That is, the gas concentration compensation amount is a reference value for detecting whether the gas quantity in the current gas storage chamber of the medical gas generator is normal, and the magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generator. The first preset compensation amount is a standard gas concentration compensation amount for the medical gas generator, that is, the first preset compensation amount is the gas concentration difference corresponding to a specific gas storage concentration of the medical gas generator, or the concentration difference value under a specified gas storage concentration of the medical gas generator. The mismatch between the gas concentration compensation amount and the first preset compensation amount indicates that the current gas concentration of the medical gas generator is different from the specified gas concentration, meaning that the current gas concentration of the medical gas generator is not equal to the specific gas concentration, and that the current gas concentration in the gas storage chamber of the medical gas generator is outside the specified gas concentration range. In this case, a second gas control signal is sent to the medical gas power supply device to control the operating state of the medical gas generator in the corresponding gas generation mode.

[0046] Further, the step of sending a second gas model signal to the medical gas power supply device when the gas concentration compensation amount does not match the first preset compensation amount includes: when the gas concentration compensation amount is less than the first preset compensation amount, detecting whether the gas concentration compensation amount is greater than or equal to the second preset compensation amount, wherein the second preset compensation amount is less than the first preset compensation amount; when the gas concentration compensation amount is greater than or equal to the second preset compensation amount, sending a trickle gas signal to the medical gas power supply device to adjust the gas production mode of the medical gas generating device to trickle gas production mode. In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration of the medical gas generating device and the standard gas storage concentration. That is, the gas concentration compensation amount is a reference value for detecting whether the current gas volume in the gas storage chamber of the medical gas generating device is normal, and the magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generating device. The first preset compensation amount is a standard gas concentration compensation amount for the medical gas generator, that is, the first preset compensation amount is the gas concentration difference corresponding to a specific gas storage concentration of the medical gas generator, or the concentration difference value under a specified gas storage concentration of the medical gas generator. If the gas concentration compensation amount is less than the first preset compensation amount but greater than or equal to the second preset compensation amount, it indicates that the current gas storage concentration of the medical gas generator is less than the specified gas storage concentration, that is, the current gas storage concentration of the medical gas generator is lower than the specific gas storage concentration, and that the current gas concentration in the gas storage chamber of the medical gas generator is at a concentration that is about to be filled. At this time, a trickle gas signal is sent to the medical gas power supply device to reduce the power supply from the medical gas power supply device to the medical gas generator, so as to control the working state of the medical gas generator in trickle gas production mode, allowing the medical gas generator to slowly produce gas and slowly fill the gas storage chamber.

[0047] Furthermore, the step of detecting whether the gas concentration compensation amount is greater than or equal to the second preset compensation amount further includes: when the gas concentration compensation amount is less than the second preset compensation amount, sending a rapid gas signal to the medical gas power supply device to adjust the gas production mode of the medical gas generator to a rapid gas production mode. In this embodiment, the gas concentration compensation amount serves as the degree of difference between the current gas storage concentration and the standard gas storage concentration of the medical gas generator. That is, the gas concentration compensation amount is a reference value for detecting whether the current gas quantity in the gas storage chamber of the medical gas generator is normal, and the magnitude of the gas concentration compensation amount directly determines the current gas storage concentration of the medical gas generator. The first preset compensation amount is a standard gas concentration compensation amount for the medical gas generator, that is, the first preset compensation amount is the gas concentration difference corresponding to a specific gas storage concentration of the medical gas generator, or the concentration difference value under a specified gas storage concentration of the medical gas generator. If the gas concentration compensation amount is less than the second preset compensation amount, it indicates that the current gas concentration of the medical gas generator is too low, meaning the current gas storage capacity of the medical gas generator is small, and that the gas storage chamber of the medical gas generator has only recently begun filling. Therefore, a rapid gas generation signal is sent to the medical gas power supply device to increase the power supply from the medical gas power supply device to the medical gas generator, so as to control the operating state of the medical gas generator in rapid gas generation mode, enabling the medical gas generator to quickly generate gas and rapidly fill the gas storage chamber.

[0048] Understandably, after the medical gas generator is powered on, the positive and negative electrodes in the electrolysis chamber are energized to electrolyze the electrolytic medium within the chamber, thereby producing hydrogen and oxygen in corresponding volume ratios. The electrolysis chamber is connected to a gas storage chamber, where the gas produced is temporarily stored for use by the user. Specifically, there are two gas storage chambers: one for storing hydrogen and the other for storing oxygen.

[0049] However, in actual use, the gas volume in the gas storage chamber increases over time. Since the gas outlet of the storage chamber is connected to the suction nozzle, when the gas storage rate in the storage chamber is greater than or equal to the gas output rate, a significant portion of the gas produced by the medical gas generator will be wasted. For example, if it is accidentally turned on and no one uses the hydrogen or oxygen; or, during normal use, the user's inhalation rate is too slow. These situations lead to unnecessary gas waste and, in severe cases, can cause hyperoxygenation in the surrounding environment, potentially leading to oxygen toxicity for the user.

[0050] To reduce the likelihood of excessive gas waste, the process of sending a mode adjustment signal to the medical gas power supply device based on the gas concentration compensation amount to adjust the gas production mode of the medical gas generator, followed by the following steps:

[0051] Obtain the partition pressure of the gas storage chamber of the medical gas generator;

[0052] Detect whether the pressure of the separation is greater than or equal to the preset pressure;

[0053] When the separating pressure is greater than or equal to the preset pressure, a first gas adjustment compensation signal is sent to the medical gas power supply device to reduce the gas preparation acceleration of the medical gas generator.

[0054] In this embodiment, the separating pressure is the internal gas pressure of the gas storage chamber, specifically, the separating pressure is the pressure on the outlet diaphragm of the gas storage chamber. During the electrolytic gas production process of the medical gas generator, hydrogen and oxygen enter the corresponding gas storage chambers for storage. The outlet diaphragm is located at the outlet of the gas storage chamber. The outlet diaphragm is compressed by the gas, thus the separating pressure is used to reflect the pressure of the gas stored in the gas storage chamber. The pressure on the outlet diaphragm is obtained through a corresponding pressure sensor. The separating pressure is the real-time gas pressure in the gas storage chamber. The separating pressure is used to display the current pressure on the outlet diaphragm in the gas storage chamber, that is, the separating pressure is used to display the current gas pressure in the gas storage chamber. The preset pressure is the maximum gas pressure of the gas stored in the gas storage chamber, that is, the maximum gas pressure that the outlet diaphragm in the gas storage chamber can withstand, and also the gas pressure corresponding to the situation where there is an excess of gas in the gas storage chamber. Thus, if the separation pressure is greater than or equal to the preset pressure, it indicates that the current gas pressure in the gas storage chamber is greater than the standard gas pressure, that is, the current gas pressure in the gas storage chamber reaches or far exceeds the maximum gas pressure that the gas diaphragm can withstand, and that is, the current gas volume in the gas storage chamber is greater than the maximum gas storage volume. At this time, there is an excess of gas in the gas storage chamber, which also indicates that the gas production rate of the medical gas generator is greater than the gas output rate. In this way, a first gas adjustment compensation signal is sent to the medical gas power supply device. The first gas adjustment compensation signal adjusts the gas production of the gas adjustment signal. For example, it reduces the rate of increase of the gas production speed of the medical gas generating device, that is, it reduces the amount of increase of the gas production speed of the medical gas generating device, so that the increase of the gas production speed of the medical gas generating device is slowed down. Specifically, it reduces the rate of increase of the electrolytic current output by the medical gas power supply device, thereby reducing the amount of increase of the gas production speed of the medical gas generating device, and thus reducing the probability of excessive gas production by the medical gas generating device. This effectively reduces the probability of excessive gas production by the medical gas generating device, and at the same time, it can also reduce the power consumption of the medical gas generating device.

[0055] Furthermore, during the long-term electrolysis process of the medical gas generator, calcified particles mixed with hydrogen or oxygen are easily generated. These particles can easily follow the gas to the through-holes on the gas outlet diaphragm and adhere to the inner wall of the through-holes, causing the diameter of the through-holes on the gas outlet diaphragm to decrease. This makes it easy for the pressure of the gas outlet diaphragm to quickly become over-pressured, i.e., the accuracy of the pressure sensing is reduced, resulting in misjudgment of the gas pressure in the gas storage chamber.

[0056] To reduce the probability of misjudging excessive gas waste, when the separating pressure is greater than or equal to the preset pressure, a first gas adjustment compensation signal is sent to the medical gas power supply device to reduce the gas preparation acceleration of the medical gas generator. The process then includes the following steps:

[0057] Obtain the temperature of the gas storage chamber;

[0058] Detect whether the temperature of the storage cavity is greater than or equal to the preset cavity temperature;

[0059] When the temperature of the storage cavity is greater than or equal to the preset cavity temperature, a second gas adjustment compensation signal is sent to the medical gas power supply device to reduce the second-order acceleration of gas preparation in the medical gas generating device.

[0060] In this embodiment, the pressure difference occurs when the pressure exceeds the standard pressure, meaning the pressure inside the gas storage chamber exceeds the maximum pressure the outlet diaphragm can withstand. In this case, the temperature of the gas storage chamber needs to be monitored. This storage chamber temperature represents the current temperature of the gas inside the chamber and is used to indicate whether the gas inside the chamber is exchanging heat with the external gas. The preset chamber temperature is the temperature at which the gas inside the storage chamber exchanges heat with the external environment at a normal rate. This preset chamber temperature serves as the standard temperature for the gas inside the storage chamber and is used to compare it with the current temperature. If the storage chamber temperature is greater than or equal to the preset chamber temperature, it indicates that the gas temperature inside the storage chamber is too high, meaning the heat exchange rate between the gas inside the storage chamber and the external gas is too low, and that the amount of gas inside the storage chamber is excessive. In this way, a second gas adjustment compensation signal is sent to the medical gas power supply device. This second gas adjustment compensation signal adjusts the rate increase of the first gas adjustment compensation signal. Specifically, the second gas adjustment compensation signal reduces the second-order acceleration of gas production in the medical gas generator; that is, it reduces the derivative of the gas production acceleration corresponding to the first gas adjustment compensation signal, thereby changing the gas production acceleration of the medical gas generator and further reducing its gas production rate. This effectively reduces the gas production rate of the medical gas generator as quickly as possible. The reduction in the acceleration and second-order acceleration of the gas production rate is a gradual and intensified process, rather than a direct cessation of gas production by the medical gas generator, since the medical gas generator still needs to produce gas.

[0061] Furthermore, the outer shell of the medical gas generating device is made of plastic, which has poor heat insulation performance. This makes the temperature inside the gas storage chamber easily affected by the external environment, that is, it is easy for heat exchange to occur with the gas inside the gas storage chamber. Therefore, in a high-temperature environment, the temperature of the storage chamber is easily affected by the external environment, which may lead to a misjudgment that there is an excess of gas in the gas storage chamber.

[0062] To further reduce the chance of false positives, the step of detecting whether the temperature of the storage cavity is greater than or equal to a preset cavity temperature includes the following steps:

[0063] Obtain the ambient temperature of the medical gas generator;

[0064] The external ambient temperature and the cavity temperature are subjected to cavity ambient temperature compensation processing to obtain the cavity ambient temperature compensation amount;

[0065] Detect whether the cavity ring temperature compensation amount matches the preset temperature compensation amount;

[0066] When the cavity ring temperature compensation amount matches the preset temperature compensation amount, a temperature update signal is sent to the hydrogen and oxygen preparation monitoring system to adjust the preset cavity temperature.

[0067] In this embodiment, the external ambient temperature refers to the temperature of the environment surrounding the outer casing of the medical gas generator. Specifically, an ambient temperature sensor is installed on the outer casing of the medical gas generator to sense the external ambient temperature. The storage chamber temperature is the gas temperature inside the gas storage chamber. Performing chamber ambient temperature compensation processing on the external ambient temperature and the storage chamber temperature involves comparing the gas temperature inside the storage chamber with the external ambient temperature to determine the difference between the gas temperature inside the storage chamber and the external ambient temperature; that is, determining the temperature difference between the gas temperature inside the storage chamber and the external ambient temperature, which is the chamber ambient temperature compensation amount. The preset temperature compensation amount is a temperature difference range between the gas temperature inside the storage chamber and the external ambient temperature; that is, the preset temperature compensation amount is a small range of temperature differences between the gas temperature inside the storage chamber and the external ambient temperature. The matching of the cavity temperature compensation amount with the preset temperature compensation amount indicates that the difference between the gas temperature inside the gas storage chamber and the external ambient temperature is too small, that is, the gas temperature inside the gas storage chamber is comparable to the external ambient temperature, which also indicates that the gas temperature inside the gas storage chamber has been affected by the external ambient temperature. At this time, there is a difference between the storage chamber temperature and the actual temperature of the gas inside the gas storage chamber, and the preset cavity temperature needs to be updated to ensure accurate judgment of the storage chamber temperature, thereby reducing the probability of misjudging the situation of excessive gas in the gas storage chamber.

[0068] In another embodiment, sending a temperature update signal to the hydrogen and oxygen preparation monitoring system to adjust the preset cavity temperature includes the following steps:

[0069] Detect whether the temperature of the storage cavity is greater than or equal to a first preset cavity temperature;

[0070] When the temperature of the storage chamber is greater than or equal to the first preset chamber temperature, a first temperature update signal is sent to the hydrogen and oxygen preparation monitoring system to increase the preset chamber temperature. In this high-temperature environment, increasing the preset chamber temperature raises the temperature judgment standard for the storage chamber, thereby reducing the probability of false positives for excessive gas.

[0071] After detecting whether the temperature of the storage cavity is greater than or equal to a first preset cavity temperature, the following steps are also included:

[0072] When the temperature of the storage cavity is lower than the first preset cavity temperature, it is detected whether the temperature of the storage cavity is greater than or equal to the second preset cavity temperature.

[0073] When the temperature of the storage chamber is greater than or equal to the second preset chamber temperature, a second temperature adjustment signal is sent to the hydrogen and oxygen preparation monitoring system to reduce the preset chamber temperature. Wherein, the second preset chamber temperature is lower than the first preset chamber temperature, indicating a low-temperature environment. Reducing the preset chamber temperature lowers the temperature judgment standard for the storage chamber, thereby reducing the probability of false positives for excessive gas.

[0074] Furthermore, during gas storage in the gas storage chamber, some moisture in the electrolytic medium in the electrolysis chamber will mix with the gas and be stored together in the gas storage chamber. If there is an excess of gas in the gas storage chamber, water droplets will condense on the membrane between the gas storage chamber and the electrolysis chamber, which may prevent the gas in the electrolysis chamber from being smoothly introduced into the gas storage chamber. This may lead to excessive gas pressure in the electrolysis chamber, thereby increasing the probability of the electrolysis chamber bursting.

[0075] To reduce the probability of the electrolysis chamber rupture in case of excessive electrolysis, when the separating pressure is greater than or equal to the preset pressure, a first gas adjustment compensation signal is sent to the medical gas power supply device to reduce the gas preparation acceleration of the medical gas generator. The process further includes the following steps:

[0076] Obtain the humidity of the gas storage chamber;

[0077] Detect whether the humidity of the storage cavity is greater than the preset cavity humidity;

[0078] When the humidity of the storage cavity is greater than the preset humidity, a disabling signal is sent to the medical gas power supply device to stop supplying power to the medical gas generating device.

[0079] In this embodiment, the pressure in the gas storage chamber exceeds the standard pressure, meaning the pressure inside the chamber is greater than the maximum pressure the diaphragm can withstand. In this case, the humidity within the gas storage chamber needs to be monitored. This humidity is the current humidity within the chamber and is used to indicate whether there is excessive moisture. The preset chamber temperature is the humidity at which water molecules in the gas storage chamber condense into droplets and block the openings in the diaphragm between the electrolysis chamber and the gas storage chamber. This preset temperature serves as the standard humidity within the gas storage chamber and is used to compare it with the current humidity. If the humidity is greater than or equal to the preset chamber temperature, it indicates that the humidity in the gas storage chamber is too high, meaning there are too many water droplets on the diaphragm, indicating an excessive amount of condensed water droplets. In this way, a disabling signal is sent to the medical gas power supply device. The disabling signal is a rate adjustment of the first gas adjustment compensation signal. Specifically, the disabling signal is used to reduce the gas production rate of the medical gas generator to 0, thereby reducing the rate at which the medical gas generator produces water molecules, prohibiting the medical gas generator from continuing to produce gas, and issuing an alarm to avoid the electrolysis chamber from bursting.

[0080] Furthermore, when the humidity in the gas storage chamber is lower than the preset chamber humidity, the electrolysis chamber continuously introduces gas into the gas storage chamber. However, when there is too little electrolytic medium in the electrolysis chamber, the electrolytic electrode is prone to dry burning. Although no more moisture is produced, that is, the humidity of the gas storage chamber can be ensured to be below the preset chamber humidity, the electrolytic electrode in the electrolysis chamber will be damaged at this time.

[0081] To reduce the probability of dry burning in the electrolysis chamber, the process of detecting whether the humidity of the storage cavity is greater than a preset cavity humidity includes the following steps:

[0082] Acquire the liquid-light signal of the electrolysis chamber;

[0083] The liquid light refractive index is obtained based on the liquid light signal;

[0084] Detect whether the liquid light refractive index matches the preset refractive index;

[0085] When the liquid refractive index does not match the preset refractive index, a low liquid warning signal is sent to the medical gas power supply device to shut down the medical gas power supply device.

[0086] In this embodiment, the liquid-light signal is the optical signal received by an optical level sensor within the electrolysis chamber. For example, the electrolysis chamber has at least one set of optical level detection components connected to its inner wall. Each optical level detection component includes an optical level transmitter and an optical level receiver. The optical level transmitter and the optical level receiver are arranged opposite to each other. The optical level transmitter emits an optical detection signal toward the area where the optical level receiver is located, and the optical level receiver receives the optical detection signal. Specifically, the optical detection signal received by the optical level receiver changes at normal and low liquid levels; that is, the optical detection signal received by the optical level receiver undergoes abrupt changes at normal and low liquid levels, facilitating the determination of the low liquid level within the electrolysis chamber. The liquid-light refractive index corresponds to the liquid level within the electrolysis chamber in real time; that is, the liquid-light refractive index is the real-time optical sensing value of the liquid-light signal, and thus corresponds to the real-time liquid level within the electrolysis chamber. The preset refractive index value is the liquid optical refractive index value corresponding to the safety warning liquid level in the electrolysis chamber. A mismatch between the liquid optical refractive index value and the preset refractive index value indicates a change in the optical detection signal received by the optical liquid level receiver in the electrolysis chamber. This means the current liquid level in the electrolysis chamber is below the safety warning liquid level, or that the current liquid level in the electrolysis chamber is too low. Therefore, when the liquid level of the electrolytic medium in the electrolysis chamber is too low, it indicates that there is insufficient electrolytic medium. A low liquid warning signal is sent to the medical gas power supply device to shut down the device, effectively preventing the positive and negative electrodes in the electrolysis chamber from dry-burning.

[0087] In another embodiment, when the liquid level in the electrolysis chamber is normal, both the optical liquid level transmitter and the optical liquid level receiver are immersed in the electrolytic medium. The optical detection signal generated by the optical liquid level transmitter is emitted through the electrolytic medium to the area where the optical liquid level receiver is located. However, when the liquid level in the electrolysis chamber is too low, the optical liquid level transmitter detaches from the electrolytic medium, and the optical detection signal received by the optical liquid level receiver changes. For example, the light emitted by the optical liquid level transmitter is refracted by the electrolytic medium, causing a relative shift between the point of impact of the light after refraction and the optical liquid level receiver. This causes the optical liquid level receiver to change from receiving the liquid optical signal to not receiving it, or vice versa. Thus, by monitoring the presence or absence of the liquid optical signal, the low liquid level condition of the electrolysis chamber can be easily determined.

[0088] In another embodiment, the optical level transmitter is not immersed in the electrolytic medium, while the optical level receiver is immersed in the electrolytic medium. When the liquid level in the electrolytic chamber is normal, the light emitted by the optical level transmitter, after refraction by the electrolytic medium, lands below the optical level receiver. However, when the liquid level in the electrolytic chamber is too low, the landing point of the light shifts upward and is received by the optical level receiver. This allows the optical level receiver to easily determine the low liquid level in the electrolytic chamber, thus facilitating low liquid level alarm.

[0089] In another embodiment, the inner wall of the electrolysis chamber is made of a reflective material, that is, the inner wall of the electrolysis chamber has a reflective function. In this case, the optical liquid level transmitter and the optical liquid level receiver are located on the same side wall of the electrolysis chamber, so that the liquid light signal is reflected by the inner wall of the electrolysis chamber and received by the optical liquid level receiver, thereby facilitating the adjustment of the low liquid level of the electrolysis chamber.

The input terminal of the medical gas preparation mainboard is connected to the control terminal of the medical gas generator, and the output terminal of the medical gas preparation mainboard is connected to the central control terminal of the medical gas power supply device. The medical gas preparation mainboard is used to obtain the gas concentration stored in the medical gas generator; perform concentration difference compensation processing between the stored gas concentration and the preset gas concentration to obtain a gas concentration compensation amount; and send a mode adjustment signal to the medical gas power supply device according to the gas concentration compensation amount to adjust the gas production mode of the medical gas generator.

[0091] In this embodiment, the medical gas preparation motherboard collects the concentration of the stored gas, facilitating the determination of the current gas concentration in the storage chamber of the medical gas generator. It then performs concentration difference compensation processing between this concentration and a preset gas concentration to accurately determine the difference between the gas concentration in the storage chamber and the standard concentration. Subsequently, based on this concentration difference, the power supply from the medical gas power supply device to the medical gas generator is adjusted by regulating the mode of gas production. This facilitates the control of the gas production mode of the medical gas generator, effectively reducing the probability of excessive gas in the storage chamber and thus significantly decreasing the risk of gas overflow.
