[0020] Figure 2 This is a schematic diagram of the oxygen parameter adjustment device for a treatment machine in one embodiment of the present invention; Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In one embodiment, such as Figure 1As shown, a method for adjusting oxygen parameters in a therapeutic machine is provided, including the following steps S10-S40:

[0023] S10. After confirming that the treatment machine is turned on, obtain the oxygen source parameters; the oxygen source parameters include the input flow rate and the input oxygen concentration.

[0024] Understandably, the therapeutic device can be activated by triggering a manual button on the device, or a virtual (or physical) button on the device's display screen or a mobile terminal connected to the device. The oxygen source can be obtained through an oxygen cylinder or a centralized oxygen supply system connected to the therapeutic device via pipeline. The input flow rate can be the flow rate of the gas input from the oxygen source. The input oxygen concentration can be the oxygen concentration in the gas input from the oxygen source. The therapeutic device can be a respiratory humidification therapeutic device equipped with an interface display system, parameter monitoring system, alarm system, time statistics system, data processing system, and therapeutic device control system. Here, the display system can be used to display the therapeutic device's operating status, real-time output gas flow rate, real-time output gas temperature, real-time output gas oxygen concentration, working parameter review display, output gas flow rate setting display, output gas temperature setting display, output gas oxygen concentration setting display, alarm text prompts, respiratory humidification therapeutic device usage time display, settings interface display, calibration interface display, etc., on the device's display screen. The parameter monitoring system can monitor real-time gas input flow rate, real-time gas input oxygen concentration, real-time output gas flow rate, real-time output gas oxygen concentration, real-time system temperature, real-time output gas temperature, real-time pipeline connection status, and real-time water tank status. The alarm system can output alarm signals when a system fault occurs; alarm signals can be visual, audio, or text alerts. The time statistics system can be used to calculate cumulative treatment time, set preset treatment times, and set screen-off times. The data processing system can collect and process data on gas input flow rate, gas input oxygen concentration, output gas flow rate, output gas oxygen concentration, system temperature, output gas temperature, and heating plate temperature. The treatment machine control system can control the turbine and proportional valves of the treatment machine.

[0025] Specifically, after confirming that the treatment machine is turned on, the data processing system obtains the gas flow rate and oxygen concentration value of the input oxygen source.

[0026] S20. Determine the turbine regulation power based on the input flow rate and the preset target output flow rate.

[0027] Understandably, the preset target output flow rate can be a pre-set output flow rate value as needed. Here, the preset target output flow rate can be determined based on the user's physical condition (e.g., the user's target arterial oxygen saturation, respiratory rate, and tidal volume). The turbine can be a mechanical device that regulates the input gas flow rate and controls the output gas flow rate. Here, the input flow rate, i.e., the gas flow rate input from the oxygen source, can be determined by the pressure of the oxygen cylinder or centralized oxygen supply device and the type of the gas delivery pipeline. If the input flow rate is too high or too low, the turbine needs to regulate the input flow rate so that the output flow rate can meet the user's needs.

[0028] Specifically, the preset target output flow rate is obtained through the display system, and the data processing system determines the turbine adjustment power based on the gas flow rate input from the oxygen source and the preset target output flow rate.

[0029] S30. Determine the proportional valve switching speed based on the input oxygen concentration and the preset target output oxygen concentration.

[0030] Understandably, the preset target output oxygen concentration can be a pre-set output oxygen concentration as needed. Here, the preset target output oxygen concentration can be determined based on the user's physical condition (e.g., the clinical condition of the user's patient; if the user has a severe respiratory disease, a higher oxygen concentration may be needed to meet their breathing needs). A proportional valve can be a mechanical device that adjusts the input gas oxygen concentration and controls the output gas oxygen concentration. Here, the input oxygen concentration, i.e., the oxygen concentration of the gas input from the oxygen source, can be determined by the mixing ratio of the oxygen concentration from the oxygen cylinder or centralized oxygen supply device with air. If the input oxygen concentration is too high or too low, a proportional valve is needed to adjust the input oxygen concentration so that the output oxygen concentration meets the user's needs.

[0031] Specifically, the preset target output oxygen concentration is obtained through the display system, and the data processing system determines the opening and closing speed of the proportional valve based on the gas oxygen concentration input from the oxygen source and the preset target output oxygen concentration.

[0032] S40. Adjust the turbine according to the turbine adjustment power, and adjust the oxygen proportional valve according to the proportional valve switching speed to put the treatment machine into operation.

[0033] Understandably, the therapy machine has two states: operating and shut-down. When the machine is in operating mode, it outputs gas. When it is in shut-down mode, there is no gas output.

[0034] Specifically, the treatment machine control system adjusts the turbine according to the turbine adjustment power, and adjusts the oxygen proportional valve according to the proportional valve opening and closing speed, so that the treatment machine enters the operating state.

[0035] This embodiment acquires oxygen source parameters after confirming the therapeutic machine is turned on, determines the turbine adjustment power based on the input flow rate and the preset target output flow rate, determines the proportional valve switching speed based on the input oxygen concentration and the preset target output oxygen concentration, adjusts the turbine according to the turbine adjustment power, and adjusts the oxygen proportional valve according to the proportional valve switching speed to bring the therapeutic machine into operation. This achieves pre-acquisition of oxygen source parameters, ensuring that the output flow rate and output oxygen concentration meet the user's needs after the therapeutic machine enters operation. Simultaneously, it achieves rapid, smooth, and precise adjustment of the output flow rate and output oxygen concentration of the humidified respiratory therapeutic machine.

[0036] Optionally, before step S10, i.e. before confirming the treatment machine is turned on, the following steps are included:

[0037] S101. Obtain the water tank installation status, pipeline status, and gas source connection status of the treatment machine. Understandably, the water tank installation status includes an installed state or an uninstalled state. The pipeline status includes a connected state or an unconnected state (e.g., a disconnected or blocked pipeline). The gas source connection status includes a connected state or an unconnected state. Here, the water tank installation status, pipeline status, and gas source connection status can be obtained through sensors (e.g., a pressure sensor or a flow sensor).

[0038] S102. If the water tank installation position is in the installed state, the pipeline is in the connected state, and the gas source is in the connected state, confirm that the treatment machine can be turned on. The "installed state" means that a water tank is installed at the water tank installation position and the water volume in the tank is greater than the preset water volume. The "connected state" means that all pipelines are connected and not blocked. Understandably, the preset water volume can be a water volume pre-set according to actual needs (e.g., the water volume required for one treatment course).

[0039] Specifically, the system acquires the water tank installation status, pipeline status, and gas source access status of the treatment machine through a parameter monitoring system. The system then determines these statuses through a data processing system. If the water tank is installed, the pipeline is connected, and the gas source is connected, the treatment machine can be turned on. If any one of these conditions is not met (i.e., at least one of the following conditions is met: water tank not installed, pipeline not connected, or gas source not connected), the treatment machine is prohibited from being turned on, and an alarm signal corresponding to the unmet condition is output.

[0040] This embodiment obtains the installation status of the water tank, the status of the pipeline, and the status of the gas source connection of the treatment machine. If the water tank is installed, the pipeline is connected, and the gas source is connected, it confirms that the treatment machine can be turned on. This realizes the self-test before the treatment machine is turned on, enabling the treatment machine to start safely and normally, achieving precise control of the treatment machine, and solving the problem of insufficient fault monitoring of the treatment machine.

[0041] Optionally, step S20, namely determining the turbine regulation power based on the input flow rate and the preset target output flow rate, includes:

[0042] S201. Confirm whether the input flow rate is greater than the preset target output flow rate. Understandably, the preset target output flow rate can be an output flow rate value preset on the display system as needed.

[0043] S202. If the input flow rate is greater than the target output flow rate, then obtain the first flow rate difference between the input flow rate and the target output flow rate.

[0044] S203. If the absolute value of the first flow rate difference is greater than the first preset flow rate threshold, then the turbine adjustment power is adjusted according to the first preset turbine adjustment rule. Understandably, the first preset flow rate threshold can be a gas flow rate value preset according to actual needs. The first preset turbine adjustment rule can be a preset rule that, when the input flow rate is greater than the target output flow rate, the turbine adjustment power is reduced to reduce the output flow rate towards the target output flow rate. The first adjustment process can be a preset adjustment of the turbine adjustment power to dynamically reduce the output flow rate to the target output flow rate.

[0045] Specifically, the data processing system confirms whether the input flow rate is greater than the preset target output flow rate. If the input flow rate is greater than the target output flow rate, the system obtains the first flow rate difference between the input flow rate and the target output flow rate. If the absolute value of the first flow rate difference is greater than the first preset flow rate threshold, it indicates that the input flow rate is much greater than the preset target output flow rate. Therefore, the turbine power needs to be reduced, and the reduction of turbine power needs to be accelerated so that the output flow rate can quickly decrease towards the target output flow rate. At the same time, the output flow rate is acquired in real time, and the turbine power is dynamically adjusted according to the difference between the real-time acquired output flow rate and the target output flow rate until the output flow rate equals the target output flow rate, while keeping the turbine power constant. If the absolute value of the first flow rate difference is less than or equal to the first preset flow rate threshold, it indicates that the input flow rate is slightly greater than the preset target output flow rate. Therefore, the turbine power needs to be reduced, but only slightly, so that the output flow rate can smoothly decrease towards the target output flow rate. At the same time, the output flow rate is acquired in real time, and the turbine power is dynamically adjusted according to the difference between the real-time acquired output flow rate and the target output flow rate until the output flow rate equals the target output flow rate, while keeping the turbine power constant.

[0046] This embodiment confirms whether the input flow rate is greater than the preset target output flow rate. If the input flow rate is greater than the target output flow rate, the first flow rate difference between the input flow rate and the target output flow rate is obtained. If the absolute value of the first flow rate difference is greater than the first preset flow rate threshold, the turbine adjustment power is adjusted according to the first preset turbine adjustment rule. This achieves fast, smooth and precise adjustment of the output flow rate of the respiratory humidification therapy machine, improving the comfort of the therapy machine.

[0047] Optionally, step S201, that is, after confirming whether the input flow rate is greater than the preset target output flow rate, further includes:

[0048] S204. If the input flow rate is less than the target output flow rate, then obtain the second flow rate difference between the input flow rate and the target output flow rate.

[0049] S205. If the absolute value of the second flow rate is greater than the second preset flow rate threshold, then the turbine adjustment power is subjected to a second adjustment process according to the second preset turbine adjustment rule. Understandably, the second preset flow rate threshold can be a gas flow rate value preset according to actual needs. The second preset turbine adjustment rule can be a preset rule that increases the turbine adjustment power when the input flow rate is less than the target output flow rate, thereby increasing the output flow rate towards the target output flow rate. The second adjustment process can be a preset adjustment of the turbine adjustment power to dynamically increase the output flow rate to the target output flow rate.

[0050] Specifically, if the input flow rate is less than the target output flow rate, a second flow rate difference between the input flow rate and the target output flow rate is obtained. If the absolute value of the second flow rate difference is greater than a second preset flow rate threshold, it indicates that the input flow rate is much less than the preset target output flow rate. Therefore, the turbine power needs to be increased, and the turbine power needs to be increased more rapidly so that the output flow rate can quickly increase to the target output flow rate. At the same time, the output flow rate is obtained in real time, and the turbine power is dynamically adjusted according to the difference between the real-time obtained output flow rate and the target output flow rate until the output flow rate equals the target output flow rate, while keeping the turbine power constant. If the absolute value of the second flow rate difference is less than or equal to the second preset flow rate threshold, it indicates that the input flow rate is slightly less than the preset target output flow rate. Therefore, the turbine power needs to be increased, but only slightly, so that the output flow rate can smoothly increase to the target output flow rate. At the same time, the output flow rate is obtained in real time, and the turbine power is dynamically adjusted according to the difference between the real-time obtained output flow rate and the target output flow rate until the output flow rate equals the target output flow rate, while keeping the turbine power constant.

[0051] This embodiment achieves fast, smooth, and precise adjustment of the output flow of the respiratory humidification therapy machine by obtaining a second flow difference between the input flow and the target output flow if the input flow is less than the target output flow, and by performing a second adjustment on the turbine adjustment power according to the second preset turbine adjustment rule if the absolute value of the second flow is greater than the second preset flow threshold, thereby improving the comfort of the therapy machine.

[0052] Optionally, the proportional valve switching speed includes the proportional valve opening speed. Step S30, namely, determining the proportional valve switching speed based on the input oxygen concentration and the preset target output oxygen concentration, includes:

[0053] S301. Confirm whether the input oxygen concentration is less than the preset target output oxygen concentration. Understandably, the preset target output oxygen concentration can be an output oxygen concentration value preset on the display system as needed.

[0054] S302. If the input oxygen concentration is less than the target output oxygen concentration, then obtain the first concentration difference between the input oxygen concentration and the target output oxygen concentration.

[0055] S303. If the absolute value of the first concentration difference is greater than the first preset concentration threshold, the opening speed of the proportional valve is determined according to the preset proportional valve opening rule. Understandably, the first preset concentration threshold can be an oxygen concentration value preset according to actual needs. The preset proportional valve opening rule can be a preset rule for opening the proportional valve according to actual needs, so as to dynamically increase the output oxygen concentration to the target output oxygen concentration.

[0056] Specifically, the data processing system confirms whether the input oxygen concentration is less than the preset target output oxygen concentration. If the input oxygen concentration is less than the target output oxygen concentration, a first concentration difference between the input oxygen concentration and the target output oxygen concentration is obtained. If the absolute value of the first concentration difference is greater than a first preset concentration threshold, it indicates that the input oxygen concentration is far less than the preset target output oxygen concentration. Therefore, the proportional valve needs to be opened, and the opening speed of the proportional valve needs to be accelerated so that the output oxygen concentration can quickly increase towards the target output oxygen concentration. At the same time, the output oxygen concentration is acquired in real time, and the proportional valve is dynamically adjusted based on the difference between the real-time acquired output oxygen concentration and the target output oxygen concentration. The opening speed is adjusted until the output oxygen concentration equals the target output oxygen concentration, while keeping the proportional valve opening degree constant. If the absolute value of the first oxygen concentration difference is less than or equal to the first preset oxygen concentration threshold, it indicates that the input oxygen concentration is slightly less than the preset target output oxygen concentration. Therefore, the proportional valve needs to be opened, and the opening speed of the proportional valve only needs to be slightly increased so that the output oxygen concentration can smoothly increase towards the target output oxygen concentration. At the same time, the output oxygen concentration is acquired in real time, and the opening speed of the proportional valve is dynamically adjusted according to the difference between the real-time acquired output oxygen concentration and the target output oxygen concentration until the output oxygen concentration equals the target output oxygen concentration, while keeping the proportional valve opening degree constant.

[0057] This embodiment confirms whether the input oxygen concentration is less than the preset target output oxygen concentration. If the input oxygen concentration is less than the target output oxygen concentration, a first concentration difference between the input oxygen concentration and the target output oxygen concentration is obtained. If the absolute value of the first concentration difference is greater than a first preset concentration threshold, the opening speed of the proportional valve is determined according to the preset proportional valve opening rule. This achieves fast, smooth, and precise adjustment of the output oxygen concentration of the respiratory humidification therapy machine, improving the comfort of the therapy machine.

[0058] Optionally, the proportional valve switching speed includes the proportional valve closing speed. After step S301, that is, after comparing the input oxygen concentration and the preset target output oxygen concentration, the method further includes:

[0059] S304. If the input oxygen concentration is greater than the target output oxygen concentration, then obtain a second concentration difference between the input oxygen concentration and the target output oxygen concentration.

[0060] S305. If the absolute value of the second concentration difference is greater than the second preset concentration threshold, the closing speed of the proportional valve is determined according to the preset proportional valve closing rule. Understandably, the second preset concentration threshold can be an oxygen concentration value preset according to actual needs. The preset proportional valve closing rule can be a preset rule for closing the proportional valve to dynamically reduce the output oxygen concentration to the target output oxygen concentration.

[0061] Specifically, if the input oxygen concentration is greater than the target output oxygen concentration, a second concentration difference between the input oxygen concentration and the target output oxygen concentration is obtained. If the absolute value of the second concentration difference is greater than a second preset concentration threshold, it indicates that the input oxygen concentration is much greater than the preset target output oxygen concentration. Therefore, the proportional valve needs to be closed, and the closing speed of the proportional valve needs to be accelerated so that the output oxygen concentration can quickly decrease towards the target output oxygen concentration. At the same time, the output oxygen concentration is acquired in real time, and the closing speed of the proportional valve is dynamically adjusted according to the real-time acquired difference between the output oxygen concentration and the target output oxygen concentration until the output oxygen concentration equals the target output oxygen concentration, while keeping the opening degree of the proportional valve unchanged. If the absolute value of the second oxygen concentration difference is less than or equal to the second preset oxygen concentration threshold, it indicates that the input oxygen concentration is slightly greater than the preset target output oxygen concentration. Therefore, the proportional valve needs to be closed, and only the closing speed of the proportional valve needs to be slightly reduced so that the output oxygen concentration can smoothly decrease towards the target output oxygen concentration. At the same time, the output oxygen concentration is acquired in real time, and the closing speed of the proportional valve is dynamically adjusted according to the real-time acquired difference between the output oxygen concentration and the target output oxygen concentration until the output oxygen concentration equals the target output oxygen concentration, while keeping the opening degree of the proportional valve unchanged.

[0062] This embodiment achieves rapid, smooth, and precise adjustment of the output oxygen concentration of the respiratory humidification therapy machine by obtaining a second concentration difference between the input oxygen concentration and the target output oxygen concentration if the input oxygen concentration is greater than the target output oxygen concentration, and determining the closing speed of the proportional valve according to the preset proportional valve closing rule if the absolute value of the second concentration difference is greater than the second preset concentration threshold, thereby improving the comfort of the therapy machine.

[0063] Optionally, after step S40, after adjusting the oxygen proportional valve according to the switching speed of the proportional valve to put the therapy machine into operation, the method further includes:

[0064] S401. Monitor and record the operating parameters of the treatment machine. Understandably, the operating parameters include gas source input flow rate, real-time gas source input oxygen concentration, real-time output gas flow rate, real-time output gas oxygen concentration, real-time system temperature, real-time output gas temperature, real-time pipeline connection status, real-time water tank status, etc.

[0065] S402. If the operating parameters exceed the preset normal parameter range, an abnormality alert message containing the operating parameters is recorded and displayed, and the treatment machine is controlled to enter a shutdown state. Understandably, the preset normal parameter range can be the normal operating range of the operating parameters preset according to actual needs (e.g., normal pipe temperature range, normal gas flow rate range, and normal oxygen concentration range, etc.).

[0066] Specifically, the operating parameters of the treatment machine are monitored in real time through parameter monitoring and stored in the storage chip. If the operating parameters exceed the preset normal parameter range, the operating parameters that exceed the preset normal parameter range are obtained and stored in the storage chip. The unusable fault points are displayed through the display system and the corresponding alarm signal is issued on the alarm system. At the same time, the treatment machine is controlled to enter the shutdown state.

[0067] This embodiment monitors and records the operating parameters of the treatment machine. If the operating parameters exceed the preset normal parameter range, it records and prompts an abnormal reminder message containing the operating parameters, and at the same time controls the treatment machine to enter a shutdown state, so that the treatment machine can operate safely and normally. This achieves precise control of the treatment machine and solves the problem of insufficient fault monitoring of the treatment machine.
