Description

Technical Field

[0001] This invention relates to the field of oxygen generator technology, and in particular to an oxygen emission regulation system for a pulse oxygen generator. Background Technology

[0002] Portable oxygen concentrators primarily consist of an air compressor and a porous zeolite mineral layer. The air compressor draws in air from the atmosphere and compresses it. This compressed air then passes through the porous zeolite mineral layer, which absorbs a large amount of nitrogen from the air. The remaining oxygen-enriched gas is then transported to the oxygen storage chamber and, along with the oxygen delivery tube, inhaled by the user. Because portable oxygen concentrators are relatively small and cannot continuously produce sufficient oxygen-enriched gas, they typically employ a pulsed oxygen supply method, releasing oxygen only when the user inhales.

[0003] Generally, the single-pulse output of a portable oxygen concentrator is calibrated by the manufacturer. The calibrated pulse frequency is usually a fixed frequency or a few frequencies, while the actual breathing frequency of users varies. When the calibrated pulse frequency differs significantly from the user's breathing frequency, it will result in either insufficient oxygen output or a significant drop in the oxygen concentration of the output oxygen, thus failing to meet the 93% medical oxygen concentration standard. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a pulse oxygen generator oxygen discharge regulation system.

The adjustment module is used to proportionally adjust the standard oxygen emission parameters according to the future respiratory rate to obtain the target oxygen emission parameters, including: determining the target oxygen emission frequency that is closest to the future respiratory rate from the first target frequency, the second target frequency and the third target frequency; According to the future respiratory rate, the oxygen excretion parameters corresponding to the target oxygen excretion rate are adjusted proportionally to obtain the target oxygen excretion parameters.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Example 1 See Figure 1 , Figure 1 This embodiment provides a schematic flowchart of an oxygen extraction regulation method for a pulse oxygen concentrator. This method is applicable to various pulse oxygen concentrators, including: S101. Obtain the standard oxygen discharge parameters of the oxygen generator at the target frequency, wherein the target frequency includes a first target frequency, a second target frequency, and a third target frequency.

[0020] See Figure 2 Step S101 includes: S1011. Obtain the standard oxygen discharge data of the oxygen generator and control the oxygen generator to discharge at a single target frequency per minute.

[0021] Standard oxygen discharge data includes gas flow rate and oxygen concentration. For example, the oxygen discharge flow rate of an oxygen concentrator is 1L / min and the oxygen concentration is 93%.

[0022] S1012. Based on the standard oxygen emission data and multiple target frequencies, calculate the standard oxygen emission parameters at multiple target frequencies, wherein the standard oxygen emission parameters include the pulse time of a single oxygen emission by the oxygen generator.

[0023] Because portable oxygen concentrators produce relatively little oxygen, they can only supply oxygen via pulses. If the pulse duration is too long, the oxygen concentration will not reach the 93% medical oxygen concentration standard. If the pulse duration is too short, the oxygen supply will be insufficient.

[0024] Therefore, the oxygen concentrator can be turned on first. The first, second, and third target frequencies do not represent only three frequencies. For example, the oxygen concentrator can be controlled to discharge oxygen at multiple target frequencies such as 15, 20, 25, 30, 35, and 40 times per minute. By detecting the flow rate and concentration of the discharged gas, the pulse time of a single pulse within the oxygen concentrator can be calibrated. Calibrating the pulse time ensures that the discharged oxygen concentration meets the concentration standard within the pulse time.

[0025] S102. Obtain the user's current breathing rate.

[0026] However, while oxygen delivery based on the target frequency may ensure that the parameters meet the standards each time, the actual breathing frequency varies from user to user. If the actual breathing frequency differs from the frequency set by the oxygen concentrator, it may lead to problems such as untimely oxygen supply. Furthermore, if medical staff manually adjust the oxygen delivery frequency unilaterally without matching data such as the pulse duration, oxygen delivery parameters, such as oxygen concentration, may change. Manually adjusting for each user each time is also a waste of manpower.

[0027] Therefore, the user's breathing rate can be obtained before each oxygen delivery, and then the oxygen delivery frequency and pulse time of the oxygen concentrator can be automatically adjusted according to the breathing rate, so that the oxygen delivery parameters of the oxygen concentrator are automatically matched with the user's breathing rate.

[0028] In one implementation, obtaining the user's current breathing rate includes: The user's inhalation and exhalation information per minute is acquired, and a respiratory waveform is obtained based on the inhalation and exhalation information; The respiratory frequency is calculated based on the information from the respiratory waveform.

[0029] Specifically, after the user wears the respiratory support device, the device can collect the user's inhalation and exhalation information within one minute. The respiratory support device is connected to the oxygen concentrator's gas storage chamber, and the respiratory waveform is obtained based on the inhalation and exhalation information within one minute.

[0030] Generally, when a user's vital signs are stable, their respiratory waveforms are regular. Therefore, two consecutive waveforms can be extracted to obtain the user's respiratory rate, that is, the distance between the previous peak and the next peak, or the distance between the previous trough and the next trough, which is considered as a complete breathing process.

[0031] Then, by calculating how many complete breathing processes occur within one minute, the user's breathing rate can be obtained.

[0032] S103. Using a Kalman filter, predict the user's future breathing rate based on the current breathing rate.

[0033] The Kalman filter is a state-space model that uses signals and noise to update the estimates of state variables using the estimates from the previous time step and the observations at the current time step, thus obtaining the current estimate. It is suitable for real-time processing and computer computation.

[0034] In this solution, since the user's current respiratory rate is collected, it can be input into the Kalman filter to predict the user's future respiratory rate. This allows the oxygen generator's oxygen output parameters to be adjusted in advance to match the user's future respiratory rate.

[0035] Specifically, it includes: Obtain the current respiratory rate for multiple existing time periods.

[0036] The current respiratory frequency of multiple existing time periods is input into a Kalman filter to predict the future respiratory frequency of the first future time period.

[0037] For example, if you want to obtain a user's future breathing frequency in the first time period, such as the breathing frequency in the second minute, you can divide the collected breathing frequency in the first minute into six time periods, each time period being ten seconds. Then, you can group the breathing frequencies of the six time periods together and input them into a Kalman filter to obtain the breathing frequency in the second minute.

[0038] To improve the prediction accuracy of the Kalman filter, the user's actual respiratory rate in the first time period in the future can be collected simultaneously. The accuracy of the predicted respiratory rate can then be verified using the actual respiratory rate, and the parameters of the Kalman filter can be adjusted based on the verification results to make the prediction results more accurate.

[0039] Similarly, after obtaining the respiratory rate in the second minute, if you want to continue predicting the respiratory rate in the second future time period, where the first future time period is before the second future time period, such as the respiratory rate in the third minute, you can use the respiratory rates in the first and second minutes as samples to predict the respiratory rate in the third minute.

[0040] S104. Adjust the standard oxygen emission parameters proportionally according to the future respiratory rate to obtain the target oxygen emission parameters.

[0041] See Figure 3 Step S104 includes: S1041. Determine the target oxygen expulsion frequency that is closest to the future breathing frequency from the first target frequency, the second target frequency, and the third target frequency.

[0042] For example, if the predicted future respiratory rate is 21 breaths per minute, which is closest to the 20 breaths per minute during the test, then 20 breaths per minute can be used as the target oxygen expulsion rate.

[0043] S1042. According to the future respiratory rate, adjust the oxygen discharge parameters corresponding to the target oxygen discharge frequency proportionally to obtain the target oxygen discharge parameters.

[0044] The standard oxygen emission parameter of 20 times per minute is used as the target oxygen emission parameter. Then, it is adjusted proportionally to 21 times per minute. For example, when the oxygen concentrator vents oxygen at the standard parameter of 20 times per minute, the single oxygen emission pulse time is 0.5 seconds, the oxygen flow rate is 0.1 L / min, and the oxygen concentration is 93%. After proportional adjustment to 21 times per minute, the single oxygen emission pulse time becomes 0.5 * 20 / 21, the oxygen flow rate is 0.1 * 21 / 20 L / min, and the oxygen concentration is 93%. The oxygen concentrator is then controlled to vent oxygen according to the converted target oxygen emission parameter.

[0045] In one embodiment, in order to reduce subsequent adjustment time, the method of this application can be used to test and adjust the respiratory rate within the normal range, or the target oxygen discharge parameters and respiratory rate can be recorded each time the user uses the device, so as to obtain and record the target oxygen discharge parameters corresponding to each respiratory rate. When the corresponding respiratory rate is detected next time, oxygen can be discharged according to the recorded target oxygen discharge parameters.

[0046] Example 2 See Figure 4 , Figure 4 A schematic diagram of the frame structure of a pulse oxygen generator oxygen emission regulation system 400 provided in this embodiment includes: The first acquisition module 401 is used to acquire the standard oxygen discharge parameters of the oxygen generator at the target frequency, wherein the target frequency includes a first target frequency, a second target frequency and a third target frequency. The second acquisition module 402 is used to acquire the user's current respiratory rate; Prediction module 403 is used to predict the user's future respiratory rate based on the current respiratory rate using a Kalman filter; The adjustment module 404 is used to proportionally adjust the standard oxygen emission parameters according to the future respiratory rate to obtain the target oxygen emission parameters.
