Description

Technical Field

[0001] This application relates to the field of medical testing, and more particularly to a flow indication method, device, electronic device, and storage medium for anesthesia machines. Background Technology

[0002] The first method uses a UI display showing the minimum flow rate threshold range and the current total fresh gas flow rate, presented on a bar chart. Both the minimum flow rate threshold and the total fresh gas flow rate are analyzed by a software algorithm based on machine parameters adjusted by clinicians and updated in real-time through the UI. When the current total fresh gas flow rate exceeds the excessive flow rate threshold, the indicator shows the total flow rate is set too high; when the current total fresh gas flow rate is below the minimum flow rate threshold, the indicator shows the total flow rate is set too low; when the total fresh gas flow rate is between the excessive and minimum flow rate thresholds, the indicator shows the total flow rate is set correctly.

[0003] The second method uses a UI that displays the minimum flow rate threshold range and the current total fresh gas flow rate, presented on two bar charts. When the total fresh gas flow rate is below the recommended minimum flow rate, the status is indicated by a red "too low"; when the total fresh gas flow rate exceeds the minimum flow rate but is greater than 1 L / min, the status is indicated by a yellow "too high"; and when the total fresh gas flow rate exceeds the minimum flow rate but is within 1 L / min, the status is indicated by a green "valid".

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] This application provides a method, device, electronic device, and storage medium for indicating the flow rate of an anesthesia machine. The method provided by this invention can be applied to any electronic device as needed, such as a server, terminal, or other electronic device. No specific limitation is made here, and for ease of description, it will be referred to as an electronic device below.

[0050] According to one aspect of the embodiments of this application, a method embodiment of a flow indication method for an anesthesia machine is provided. Figure 1 A flowchart of a flow rate indication method for an anesthesia machine provided in this application embodiment is shown below. Figure 1 As shown, the method includes:

[0051] Step S11: Obtain the mixed gas and anesthetic gas, and input the mixed gas and anesthetic gas into the patient's breathing circuit. The mixed gas is obtained by mixing multiple component gases in a preset ratio.

[0052] The method provided in this application is applied to a smart device deployed on an anesthesia machine. The smart device can control the anesthesia machine to administer anesthesia and mechanical ventilation to the patient. Based on this, during surgery or treatment, the smart device can receive gas delivery commands and, based on these commands, obtain a mixed gas and an anesthetic gas. The mixed gas can be obtained by pre-mixing multiple gases in a preset ratio. For example, the mixed gas can be oxygen (O2), air, or nitrous oxide (N2O) mixed at different flow rates to create fresh gas. Then, the mixed gas and the anesthetic gas are introduced into the patient's breathing circuit so that the patient can inhale the oxygen and anesthetic gas from the fresh gas in the breathing circuit and exhale excess oxygen, anesthetic gas, and carbon dioxide.

[0053] Step S12: Obtain the gas consumption corresponding to multiple gas consumption indicators based on the breathing circuit, and calculate the total gas consumption using the gas consumption corresponding to the gas consumption indicators.

[0054] In this embodiment of the application, in order to obtain the gas consumption in the breathing circuit more accurately, multiple gas consumption indicators are set to detect the breathing circuit. The gas consumption indicators include: oxygen consumption, anesthetic gas consumption, circuit leakage, and carbon dioxide absorption by the soda lime canister.

[0055] It should be noted that, as Figure 2 As shown, in the breathing circuit, part of the gas exhaled by the patient goes to the exhaust system, and part of the carbon dioxide is absorbed by the soda lime canister. Alternatively, due to potential leaks in the breathing circuit, some gas may leak out and be consumed. Therefore, by considering oxygen consumption, anesthetic gas consumption, circuit leakage, and the amount of carbon dioxide absorbed by the soda lime canister, the total gas consumption can be calculated more accurately.

[0056] In this embodiment of the application, before obtaining the gas consumption corresponding to multiple gas consumption indicators based on the breathing circuit, the method further includes: detecting multiple gas parameters corresponding to the patient based on the breathing circuit; wherein, the gas parameters include: inspiratory volume Vti, expiratory volume Vte, inhaled oxygen concentration FiO2, exhaled oxygen concentration EtO2, anesthetic gas inhalation concentration FiAA, anesthetic gas exhalation concentration EtAA, respiratory rate Rate, carbon dioxide inhalation concentration FiCO2, and carbon dioxide exhalation concentration EtCO2. It should be noted that the above gas parameters are obtained by the intelligent device using an AG module with paramagnetic oxygen for gas monitoring and calculation.

[0057] In this embodiment of the application, the gas consumption corresponding to multiple gas consumption indicators is obtained based on the breathing circuit, including the following steps A1-A2:

[0058] Step A1: Calculate the first product between inspiratory volume and inspiratory oxygen concentration, and the second product between expiratory volume and expiratory oxygen concentration.

[0059] Step A2: Obtain the difference between the first product and the second product, and multiply the difference by the respiratory rate as the oxygen consumption.

[0060] In this embodiment of the application, the formula for calculating oxygen consumption is as follows:

[0061] VO2f = (Inspiratory volume Vti × Inspired oxygen concentration FiO2 - Expiratory volume Vte × Expiratory oxygen concentration EtO2) × Respiratory rate Rate. Where VO2f is the oxygen consumption.

[0062] In this embodiment of the application, the gas consumption corresponding to multiple gas consumption indicators is obtained based on the breathing circuit, including the following steps B1-B2:

[0063] Step B1: Calculate the third product between the inhaled volume and the inhaled concentration of the anesthetic gas, and the fourth product between the expiratory volume and the exhaled concentration of the anesthetic gas.

[0064] Step B2: Obtain the difference between the third product and the fourth product, and use the product of the difference and the respiratory rate as the anesthetic gas consumption.

[0065] In this embodiment, the formula for calculating the consumption of anesthetic gas is as follows:

[0066] VAGf = (Inspiratory volume Vti × Anesthetic gas inhalation concentration FiAA - Expiratory volume Vte × Anesthetic gas exhalation concentration EtAA) × Respiratory rate Rate. Wherein, VAGf is the oxygen consumption.

[0067] In this embodiment of the application, the gas consumption corresponding to multiple gas consumption indicators is obtained based on the breathing circuit, including the following steps C1-C2:

[0068] Step C1: Calculate the difference between the inspiratory volume and the expiratory volume.

[0069] Step C2: The difference between the difference and the respiratory rate is taken as the loop leakage.

[0070] In this embodiment of the application, the formula for calculating the leakage of the calculation circuit is as follows:

[0071] Leakf = (Inspiratory volume Vti - Expiratory volume Vte) × Respiratory rate Rate. Where Leakf is the leakage rate in the circuit.

[0072] In this embodiment of the application, the gas consumption corresponding to multiple gas consumption indicators is obtained based on the breathing circuit, including the following steps D1-D2:

[0073] Step D1: Calculate the fifth product between expiratory volume and exhaled carbon dioxide concentration, and the sixth product between inhaled volume and inhaled carbon dioxide concentration.

[0074] Step D2: Obtain the difference between the fifth and sixth products, and multiply the difference by the respiratory rate as the amount of carbon dioxide absorbed by the soda lime canister.

[0075] In this embodiment of the application, the formula for calculating the amount of carbon dioxide absorbed by the soda lime container is as follows:

[0076] VCO2f = (Expiratory volume Vte × Exhaled carbon dioxide concentration EtCO2 - Inspiratory volume Vti × Inhaled carbon dioxide concentration FiCO2) × Respiratory rate Rate. Where VCO2f is the amount of carbon dioxide absorbed by the soda lime canister.

[0077] In this embodiment of the application, after obtaining the gas consumption corresponding to each gas consumption index, the total gas consumption is obtained by summing the gas consumption corresponding to each gas consumption index.

[0078] Step S13: Detect the total flow rate of the mixed gas in the breathing circuit.

[0079] In this embodiment, the smart device can use a flow meter deployed in the breathing circuit to detect the total flow rate of the mixed gas.

[0080] Specifically, when the gas mixture enters the breathing circuit from the gas source, the flowing gas passes through a flow meter. The flow meter collects information on the velocity and volume of the gas flow. By combining the velocity and volume, the total flow rate of the gas mixture can be obtained. A smart device acquires the flow meter's measurement data through sensors connected to it. This data can be processed and analyzed by the smart device's chip or processor. The smart device can then identify and calculate the total flow rate of the gas mixture based on the measurement data, and display the results or perform other related processing.

[0081] By utilizing flow meters deployed in the breathing circuit, smart devices can monitor the total flow rate of the mixed gas in real time. This is crucial for medical equipment such as ventilators and anesthesia machines, as well as other applications requiring precise control of gas flow.

[0082] Step S14: Determine the correlation information between total flow rate and total gas consumption, and generate flow indication information for the anesthesia machine based on the correlation information. The flow indication information is used to indicate whether the total flow rate is effective for the total gas consumption.

[0083] In this embodiment of the application, determining the correlation information between total flow rate and total gas consumption, and generating flow indication information for the anesthesia machine based on the correlation information, includes the following steps E1-E3:

[0084] Step E1: Generate multiple detection intervals based on the total gas consumption, where different detection intervals are used to represent different flow rates.

[0085] In this embodiment, multiple detection intervals are generated based on the total gas consumption. Different detection intervals are used to represent different flow rates. Each detection interval represents a different flow range, which can be used to indicate the amount of gas consumed. The purpose of generating multiple detection intervals is to more accurately detect and represent gas consumption at different flow rates.

[0086] Step E2: Determine the target detection interval that matches the total flow rate from multiple detection intervals, and use the target detection interval as the correlation information between the total flow rate and the total gas consumption.

[0087] In this embodiment, a target detection interval matching the total flow rate is determined from multiple detection intervals. The target detection interval corresponding to the total flow rate is determined by comparing the total flow rate with the ranges of each detection interval. The target detection interval represents the specific range of the total flow rate and can be used to represent the magnitude of the total flow rate. Using the target detection interval as correlation information between the total flow rate and the total gas consumption, it can be used to calculate the gas consumption corresponding to the total flow rate.

[0088] Step E3: Determine the location information of the total flow within the target detection interval, and generate flow indication information based on the location information and the target detection interval.

[0089] In this embodiment, the location information of the total flow rate within the target detection interval is determined. By comparing the total flow rate with the upper and lower limits of the target detection interval, the specific location of the total flow rate can be determined. Based on the location information of the total flow rate within the target detection interval, corresponding flow indication information can be generated. The flow indication information tells us the specific range of the total flow rate, thereby understanding the gas consumption situation. Through the flow indication information, gas consumption can be conveniently monitored and managed.

[0090] As an example, the software algorithm has already processed the dynamic minimum traffic threshold range, eliminating the need for dynamic UI changes. Figure 3As shown, the total gas consumption is the starting point of each interval. The triangle indicates the measured value of the current total flow rate after algorithm conversion, and the values ​​below the bars represent the total flow rate. If the triangle is in the middle detection interval, it means that the currently set fresh gas flow rate is effective, saving anesthetic and fresh gas. If the triangle is in the uppermost detection interval, it means that the currently set fresh gas flow rate is too high, wasting anesthetic and fresh gas. If the triangle is in the lowermost detection interval, it means that the currently set fresh gas flow rate is too low, resulting in insufficient fresh gas supply. This allows clinicians to adjust ventilation parameters to ensure that the current fresh gas is at an appropriate level of conservation.

[0091] The method provided in this application obtains the gas consumption corresponding to multiple gas consumption indicators by detecting the breathing circuit, which can accurately obtain the total gas consumption. At the same time, it generates a flow indication by utilizing the correlation between the total flow rate of fresh gas and the total gas consumption. It does not need to present a lot of parameters to the user. Compared with the prior art, it can represent the flow indication more intuitively, so that the user can quickly determine whether the current flow indication is appropriate and make adjustments.

[0092] In this embodiment, the current flow indication and total flow data are acquired via a sensor connected to the flow meter. A suitable flow range is set according to application requirements and safety standards. This range should include both minimum and maximum limits to ensure the gas flow rate remains within a safe and effective range. The current flow indication is compared to the set flow range. If the current flow indication is within the appropriate range, the flow is normal and no adjustment is required. If the flow indication is outside the range, adjustment is necessary. The gas flow rate is adjusted via an automatic control system. Based on the current flow indication and the set target range, the system can automatically adjust the settings of the gas flow controller to maintain the flow rate within the appropriate range.

[0093] For example, a flow meter sensor connected to the breathing circuit acquires the current flow indication and total flow data. Based on the requirements and safety standards of the medical device, a suitable flow range is set, such as a minimum of 0.5 liters per minute and a maximum of 10 liters per minute. The current flow indication is compared to the set flow range. Assuming the current flow indication is 6 liters per minute, the flow rate is within the appropriate range. Based on the current flow indication and the set target range, the system can automatically adjust the settings of the gas flow controller. For example, if the current flow indication is below the set range, the system increases the gas flow rate and adjusts the opening of the gas flow controller. If the current flow indication exceeds the set range, the system decreases the gas flow rate and adjusts the opening of the gas flow controller.

[0094] Monitor the adjusted flow rate to ensure it remains within the appropriate range and provide timely feedback to the user. Flow information and adjustment results can be provided to the user through displays, indicator lights, or alarm systems.

[0095] By automatically determining whether the current flow rate indication is appropriate and making adjustments accordingly, the gas flow rate can be ensured to remain within a safe and effective range, providing reliable flow control. This reduces the possibility of human intervention and operational errors, improving the system's automation level and user experience.
