[0060] Those skilled in the art will understand that Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0061] In one embodiment, such as Figure 2 As shown, a pulse oxygen supply method for a ventilator is provided, which is applied to... Figure 1 Taking the ventilator as an example, the explanation includes:

[0062] S201, while supplying oxygen to the target user, acquires the gas pressure and gas flow rate parameters output by the ventilator.

[0063] In this embodiment, while the ventilator continuously provides basic airflow and oxygen support to the target user, the gas pressure (e.g., airway pressure Paw) and gas flow rate parameters (e.g., flow rate) in the breathing circuit are continuously and synchronously collected using pressure and flow sensors integrated into the ventilator. Furthermore, after necessary amplification, filtering, and analog-to-digital conversion, the aforementioned gas pressure and gas flow rate parameters can be converted into a digital parameter data stream that can be analyzed by a processor.

[0064] S202 determines the first pulse time of the ventilator based on gas pressure and gas flow rate parameters.

[0065] In this embodiment, the ventilator executes a preset algorithm based on real-time acquired gas pressure and flow rate parameters. For example, it can first analyze flow rate waveform characteristics (e.g., identifying the inspiratory start point and peak flow rate), and combine this with real-time pressure changes (e.g., the rate of pressure change required to overcome airway resistance and lung compliance) to dynamically assess the user's current respiratory mechanics and inspiratory effort. Furthermore, a specific computational model (e.g., based on flow rate integrals, pressure-flow rate relationships, or prediction algorithms) can be used to calculate in real-time an initial pulse oxygen delivery time window suitable for the current respiratory cycle, defined as the first pulse time, thereby covering the critical period in the inspiratory phase where airflow is relatively stable and oxygen delivery efficiency is highest.

[0066] S203, based on the breathing data input by the target user, adjust the first pulse time to determine the second pulse time.

[0067] In this embodiment, the ventilator receives key respiratory data input by medical personnel through a human-machine interface. For example, the respiratory data may be a preset target inspiratory time, target respiratory rate, or inspiratory trigger sensitivity. The first pulse time is compared and logically processed with the respiratory data. Factors that the adjustment algorithm may consider include: whether the percentage of the first pulse time to the preset target inspiratory time is within a preset optimization range; whether the deviation between the current respiratory rate and the target respiratory rate requires adjustment of the pulse time to match the overall respiratory rhythm; or the influence of the inspiratory trigger sensitivity on the pulse start point. Based on this, the system fine-tunes or recalibrates the first pulse time to generate the final optimized pulse time for the current respiratory cycle, defined as the second pulse time.

[0068] Optionally, the target user can record a segment of their actual breathing, maintaining steady breathing to closely resemble real-life conditions. The breathing signal is the raw pressure and flow rate signal value collected by the ventilator's pressure and flow sensor, representing the sensor's original value. Further, the collected breathing signal undergoes denoising processing (denoising methods include, but are not limited to, wavelet transform, Butterworth, etc.). By analyzing the processed breathing signal and the breathing waveform per unit time, a customized inspiratory-to-expiratory ratio and inspiratory-expiratory duration are obtained. The second pulse time is then determined based on this customized ratio and duration.

[0069] Optionally, the ventilator can analyze the target user's respiratory ratio / breathing duration based on continuous respiratory sampling analysis and predict the next breath, so that oxygen supply is stopped within a unit of time before the end of expiration and oxygen supply is provided within a unit of time before the start of inspiration.

[0070] S204 provides pulsed oxygen supply based on the second pulse time of the ventilator.

[0071] In this embodiment, during the confirmed inspiratory phase, the ventilator outputs a control command according to the second pulse time. This control command drives the oxygen delivery valve to open within the time window specified by the second pulse time. During this time window, high-concentration oxygen is injected or mixed into the ventilator's main airflow in a controlled flow or pressure manner, and directly delivered to the patient's airway. After the second pulse time ends, the oxygen valve immediately closes, stopping the pulsed oxygen supply. The ventilator resumes providing basal gas support until the next inspiratory phase triggers a new cycle of pulsed oxygen supply.

[0072] Optionally, the start point of the intake phase is typically determined by a flow rate or pressure trigger signal.

[0073] In the aforementioned pulse oxygen delivery method for a ventilator, while providing oxygen to the target user, the gas pressure and flow rate parameters output by the ventilator are acquired. Based on these parameters, the first pulse duration is determined. The first pulse duration is then adjusted based on the respiratory data input by the target user to determine the second pulse duration. Pulsed oxygen delivery is then performed based on the second pulse duration. Determining the first pulse duration matched to the target user based on the ventilator's output gas pressure and flow rate parameters improves the accuracy and matching degree of the first pulse duration. Furthermore, adjusting the first pulse duration based on respiratory data enhances the reliability and accuracy of the final obtained second pulse duration.

[0074] In one embodiment, one implementation of the above-described S202 is provided, such as... Figure 3 As shown, the above-mentioned "determining the first pulse time of the ventilator based on gas pressure and gas flow rate" includes:

[0075] S301, determine the respiratory rate based on gas pressure and the average tidal volume per unit time.

[0076] In this embodiment, gas pressure and gas flow rate signals in the ventilator circuit are acquired in real time. The tidal volume of each respiratory cycle per unit time is calculated by integrating the gas flow rate signal over time. The arithmetic mean of the tidal volume within the window is continuously calculated based on a preset sliding time window. The waveform periodicity characteristics of the gas pressure signal are analyzed simultaneously to identify the time interval between the start points of continuous inhalation. The dynamic respiratory rate is output by combining the reciprocal operation of the time interval with filtering.

[0077] For example, the respiratory rate can be as shown in Equation 1:

[0078] (Equation 1)

[0079] Where RR is the respiratory rate; VE is the tidal volume per unit time, which is directly measured by the ventilator; and TV is the average tidal volume per unit time, which is measured by the ventilator's flow sensor.

[0080] Optionally, the breathing state is divided into inspiratory and expiratory states, which are determined by analyzing the ventilator pressure and flow signals. The pressure and flow signals are data from the ventilator sensors, determined by the rise and fall of the respiratory pressure curve. The respiratory ratio is directly output by the ventilator and is the ratio of the rise to fall time of the pressure and flow data.

[0081] S302, determine the first pulse time based on respiratory rate, tidal volume corresponding to the target time, and peak inspiratory flow rate.

[0082] In this embodiment, a baseline time reference can be generated first based on respiratory rate and preset rules, and then the baseline time can be scaled and adjusted according to the ratio of real-time tidal volume to the mean tidal volume. Finally, time compression constraints are applied by combining the comparison results of peak inspiratory flow rate and set threshold, and the first pulse time is output.

[0083] In the above-mentioned embodiments, the three dynamic parameters of respiratory rate, real-time single tidal volume and peak inspiratory flow rate are integrated, and the first pulse time is output through a hierarchical decision-making mechanism. This allows the timing of pulse oxygen delivery to adapt synchronously to the overall breathing rhythm, immediate ventilation needs and changes in airway status of the target user, thereby improving the accuracy of the first pulse time.

[0084] In one embodiment, one implementation of S302 described above is provided, such as... Figure 4 As shown, the above-mentioned "determining the first pulse time based on respiratory rate, tidal volume corresponding to the target time, and peak inspiratory flow rate" includes:

[0085] S401, determine the first inspiratory duration for oxygen delivery by the ventilator based on the tidal volume and peak inspiratory flow rate at the target time.

[0086] In this embodiment, the first inspiratory duration during ventilator oxygen supply can be the ratio of tidal volume to peak inspiratory flow. For example, the first inspiratory duration can be as shown in Equation 2:

[0087] (Equation 2)

[0088] in, The duration of the first inhalation, of which Tidal volume is measured by the respirator sensor, and peak inspiratory flow rate is the difference between the maximum and minimum values ​​of the pressure and flow sensor per unit time.

[0089] S402, determine the first expiratory duration when the ventilator is supplying oxygen based on the first inspiratory duration and respiratory rate.

[0090] In this embodiment of the application, the first exhalation duration can be as shown in Equation 3:

[0091] (Equation 3)

[0092] Where RR is the respiratory rate. The duration of the first inhalation. The duration of the first exhalation.

[0093] S403, determine the first pulse time based on the first exhalation duration and the first inhalation duration.

[0094] In this embodiment, oxygen is supplied within a unit time before the start of the inspiratory phase and stopped within a unit time before the end of the expiratory phase by using the pulse oxygen supply module and corresponding parameters in the ventilator.

[0095] Optionally, the first expiratory duration and the first inspiratory duration can be acquired in real time. The first expiratory duration and the first inspiratory duration can be directly correlated through a preset pulse time decision function: the first inspiratory duration is used as the basic time reference, and a compression factor is dynamically generated based on the ratio of the first expiratory duration to the first inspiratory duration (K_comp = min(1.0, T_exp1 / (T_insp1 × γ)), where γ is a preset expiratory safety factor; the final output first pulse time is T_pulse1 = first inspiratory duration × K_comp, ensuring that the pulse oxygen supply window is strictly limited to the inspiratory phase and automatically adapted to the respiratory cycle ratio.

[0096] In the above-mentioned embodiments, the pulse time is dynamically constrained by coupling the duration ratio of the inspiratory and expiratory phases, so that the oxygen supply window automatically scales up and down with the relative duration of the expiratory phase on the inspiratory duration basis. This ensures that the pulse oxygen supply fully covers the effective inspiratory period and actively avoids potential conflicts with the expiratory phase.

[0097] In one embodiment, such as Figure 5 As shown, the pulse oxygen supply method of the above-mentioned ventilator also includes:

[0098] S404 uses sensors on the ventilator to obtain the duration of inspiratory pauses.

[0099] Based on this, the aforementioned "determining the first inspiratory duration during mechanical oxygen delivery based on the tidal volume and peak inspiratory flow rate corresponding to the target time" includes:

[0100] S405 determines the first inspiratory duration during ventilator oxygen delivery based on the inspiratory pause duration, the tidal volume corresponding to the target time, and the peak inspiratory flow rate.

[0101] In this embodiment of the application, during continuous monitoring of the ventilator, the airway pressure signal is collected in real time by a high-response pressure sensor. Combined with the gas flow rate detected by the flow sensor as zero, when it is determined that the current respiratory cycle has entered the inspiratory phase and the flow rate is continuously lower than the preset threshold, the inspiratory pause duration detection is initiated. Based on the time interval between the pressure signal from the pressure formation point at the end of the inspiratory plateau (where the pressure change rate approaches zero) to the trigger point of the expiratory valve, the accurate inspiratory pause duration parameter is output after digital filtering and state machine verification.

[0102] Furthermore, the first inspiratory duration during mechanical oxygenation is determined based on the inspiratory pause duration, the tidal volume corresponding to the target time, and the peak inspiratory flow rate.

[0103] Optional, such as Figure 6As shown, the above-mentioned "determining the first inspiratory duration during mechanical oxygen delivery based on the inspiratory pause duration, the tidal volume corresponding to the target time, and the peak inspiratory flow rate" includes:

[0104] S501, determine the ratio of tidal volume to peak inspiratory flow rate.

[0105] S502, the sum of the ratio and the inhalation pause duration is determined as the first inhalation duration.

[0106] In this embodiment, the ratio of tidal volume to peak inspiratory flow rate can be expressed as: Furthermore, the sum of the above ratio and the inhalation pause duration is determined, and this sum is defined as the first inhalation duration. For example, the first inhalation duration is shown in Equation 4:

[0107] (Equation 4)

[0108] in, This refers to the duration of apnea.

[0109] In the above-mentioned embodiments, the identification of the inspiratory pause period is achieved without adding hardware by utilizing the coupling characteristics of existing sensor signals, and the detection results are not affected by slight airway fluctuations by using the platform pressure stability criterion, thereby improving the accuracy of the first inspiratory duration and the first expiratory duration.

[0110] In one embodiment, one implementation of the above-described S204 is provided, such as... Figure 7 As shown, the above-mentioned "performing pulsed oxygen supply according to the second pulse time of the ventilator" includes:

[0111] S601 analyzes the second pulse time of the ventilator to determine the second inspiratory duration and the second expiratory duration for the target user.

[0112] In this embodiment, the respiratory waveform of the target user is monitored in real time by the ventilator pressure and flow sensors. After the second pulse time is executed, the inspiratory termination time is accurately marked based on the zeroing characteristics of the flow signal and the pressure plateau formation point. The start point of the current respiratory cycle is traced back in reverse, and the duration of the complete inspiratory phase is calculated as the second inspiratory duration. The second expiratory duration is output synchronously based on the time interval from the triggering of the expiratory valve to the triggering of the next inspiratory phase, after noise suppression processing.

[0113] S602, determine the start time and duration of pulse oxygen supply based on the second inhalation duration and the second exhalation duration.

[0114] In this embodiment, the starting position of the efficient oxygen supply window, i.e. the start time of pulse oxygen supply, is determined by superimposing a preset delay offset on the inhalation trigger point and combining it with the second inhalation duration. The final oxygen supply window, i.e. the oxygen supply duration, is generated based on the minimum value of the second pulse time and the dynamic safety upper limit, and by applying a reverse constraint based on the remaining duration of the second exhalation duration.

[0115] Optionally, the dynamic safety limit can be the product of the second inhalation duration and a preset percentage coefficient.

[0116] S603 provides pulsed oxygen supply based on the start time and duration of oxygen supply.

[0117] In this embodiment, an opening command is sent to the high-speed proportional oxygen supply valve at a specified time. Oxygen supply is immediately interrupted when the oxygen supply duration ends or premature termination of inspiration is detected (abnormal flow / pressure), and the actual execution parameters are recorded. Optionally, the oxygen flow rate can be monitored in real time via a secondary flow meter during oxygen supply. If the flow rate exceeds the threshold corresponding to the oxygen production level, PID closed-loop regulation is triggered.

[0118] In the above-mentioned application embodiments, a user's real breathing pattern profile is established by reverse derivation of the respiratory phase sequence. Based on this, the starting position and duration of pulse oxygen supply are dynamically constrained, so that oxygen delivery is accurately matched with individualized respiratory mechanics characteristics. Finally, the synchronization of oxygen supply parameters and hardware response is achieved through a multi-instruction collaborative execution mechanism (S603).

[0119] In one embodiment, a complete pulsed oxygen delivery method for a ventilator is provided, comprising:

[0120] S1, while supplying oxygen to the target user, acquires the gas pressure and gas flow rate parameters output by the ventilator.

[0121] S2, determine the respiratory rate based on gas pressure and the average tidal volume per unit time.

[0122] S3. Determine the first inspiratory duration for oxygen delivery by the ventilator based on the tidal volume and peak inspiratory flow rate at the target time.

[0123] S4 obtains the duration of inspiratory pause through the ventilator's sensors.

[0124] S5, determine the ratio of tidal volume to peak inspiratory flow rate.

[0125] S6. The sum of the ratio and the inhalation pause duration is determined as the first inhalation duration.

[0126] S7. Determine the first pulse time based on the first exhalation duration and the first inhalation duration.

[0127] S8 adjusts the first pulse time based on the breathing data input by the target user to determine the second pulse time.

[0128] S9 analyzes the second pulse time of the ventilator to determine the second inspiratory duration and the second expiratory duration for the target user.

[0129] S10, determine the start time and duration of pulse oxygen supply based on the second inhalation duration and the second exhalation duration.

[0130] S11 provides pulsed oxygen supply based on the start time and duration of oxygen supply.

[0131] In the aforementioned pulse oxygen delivery method for a ventilator, while providing oxygen to the target user, the gas pressure and flow rate parameters output by the ventilator are acquired. Based on these parameters, the first pulse duration is determined. The first pulse duration is then adjusted based on the respiratory data input by the target user to determine the second pulse duration. Pulsed oxygen delivery is then performed based on the second pulse duration. Determining the first pulse duration matched to the target user based on the ventilator's output gas pressure and flow rate parameters improves the accuracy and matching degree of the first pulse duration. Furthermore, adjusting the first pulse duration based on respiratory data enhances the reliability and accuracy of the final obtained second pulse duration.
