Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an automatic condensate regulating device and method for medical breathing tubing. Background Technology

[0002] During medical respiratory therapy, a large amount of condensation is generated in the breathing tubing. This condensation is formed when inhaled air, after being heated and humidified by the humidifier, condenses into liquid water in the tubing. The accumulation of condensation can lead to the following serious problems: Increased airway resistance: Condensation reduces the effective diameter of the tubing, increasing airflow resistance and requiring more effort to breathe; Risk of aspiration: Condensation may flow back into the patient's airway, causing suffocation or lung infection; Equipment damage: Condensation entering precision components such as flow sensors and exhalation valves can cause ventilator malfunctions; Condensation buildup increases airflow resistance in the tubing, affecting ventilation and even endangering the patient's life; Excessive condensation may also leak into the breathing membrane, creating a risk of overpressure.

[0003] In existing technologies, condensate drainage typically involves adding a condensate collection block between the inlet and outlet tubing. Condensate automatically flows into the collection block, and when it's nearly full, medical staff manually disassemble it to empty the water before reinstalling it. This disassembly and drainage method is currently cumbersome and may disrupt the ventilator's oxygen delivery. While some breathing circuits are equipped with condensate collection devices, these are mostly manually drained, which is tedious and prone to leaks. Some automatic drainage devices suffer from poor versatility and incompatibility with tubing from different manufacturers.

[0004] Therefore, the urgent technical problem to be solved is how to provide an automatic condensate regulating device and method for medical breathing tubing, so as to improve the intelligence and safety reliability of condensate discharge, avoid the cumbersome operation of manual discharge, and improve the versatility of the device.

[0026] The technical solutions of the embodiments of this application 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 this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Example 1 like Figure 1-3 As shown, this application provides an automatic condensate regulating device for medical breathing tubing. The device includes: a water collection cup 1 and an automatic regulating device 2. The water collection cup 1 is connected to the ventilation tube in the breathing tubing to collect condensate from the tubing. The automatic regulating device 2 is detachably connected to the water collection cup 1. The automatic regulating device 2 includes: a water level detection unit for detecting the water level of the condensate in the water collection cup 1 and outputting a water level signal; a control unit electrically connected to the water level detection unit for receiving the water level signal and generating control commands; and a drainage execution unit electrically connected to the control unit for performing drainage or stopping drainage operations according to the control commands. Specifically, when the water level detection unit detects that the condensate has reached a preset upper water level line, the control unit controls the drainage execution unit to start drainage; when the condensate is detected to have dropped to a preset lower water level line, the control unit controls the drainage execution unit to stop drainage. The water collection cup 1 can collect the condensate from the breathing tubing, and the automatic regulating device 2 automatically regulates the condensate in the water collection cup 1 to ensure that the condensate in the water collection cup 1 is always within a safe range.

[0028] like Figure 1-3 As shown, the automatic adjustment device 2 includes: a housing 27 and a top cover 28, the top cover 28 being detachably connected to the top of the housing 27, and the top cover 28 and the housing 27 forming a cavity; a water level detection unit, a control unit, and a drainage execution unit are disposed within the cavity. The water level detection unit is a water level sensor 25; the control unit is a control circuit board 24; and the drainage execution unit is a water pump 26.

[0029] like Figure 1 As shown, the top of the water cup 1 is equipped with a Y-shaped conical connector 3 for connecting to the ventilation tube in the breathing circuit. The Y-shaped conical connector 3 is a standard 22mm outer Y-shaped conical connector, which can connect to the ventilation tube in the breathing circuit and is compatible with medical breathing circuits from different manufacturers, enabling intelligent automatic regulation of condensate in the breathing circuit. When a condensate collection device exists in the breathing circuit, an automatic adjustment device 2 can be equipped separately to automatically regulate the condensate in the breathing circuit. The automatic adjustment device 2, as an intelligent adjustment device, is not dependent on a specific manufacturer's breathing circuit and has universality.

[0030] like Figure 3As shown, the drainage unit includes: a water pump 26; the inlet of the water pump 26 is connected to the water receiving cup 1 via a puncture tube 23; the outlet of the water pump 26 is connected to the condensate discharge tank via a drain pipe 22. One end of the drain pipe 22 is connected to the outlet of the water pump 26, and the other end is connected to the condensate discharge tank, thereby draining the condensate from the breathing tubing into the breathing system.

[0031] In a preferred embodiment of the present invention, the water pump 26 is preferably a miniature water pump. One end of the puncture tube 23 is connected to the inlet of the miniature water pump, and the other end is punctured and connected to the water cup 1. The puncture tube 23 has a built-in sealing structure to ensure that the pipeline is sealed after puncture.

[0032] like Figure 2 As shown, the automatic adjustment device 2 also includes an automatic adjustment device buckle 21, which is used to securely connect with the water cup 1.

[0033] In a specific embodiment of the present invention, the water level sensor 25 is installed on the automatic adjustment device 2 and aligned with the water receiving cup 1.

[0034] In a specific embodiment of the present invention, the water level detection unit includes an upper water level sensor and a lower water level sensor, respectively set corresponding to preset upper and lower water level lines. The upper and lower water level sensors are installed in the automatic adjustment device latch 21. When the condensate in the water cup 1 reaches the preset upper water level line, the automatic adjustment device 2 automatically releases the condensate in the water cup 1. When the condensate in the water cup 1 reaches the preset lower water level line, the automatic adjustment device 2 stops releasing the condensate in the water cup 1. This cycle repeats continuously to avoid the accumulation of condensate in the breathing tube, which would increase the airflow resistance of the tube and reduce the risk of pressure buildup in the leaking breathing membrane.

[0035] As a specific embodiment of the present invention, the water pump 26 opens or closes the drainage channel according to the instructions of the control unit.

[0036] As a specific embodiment of the present invention, the preset upper water level line is set to 70%-80% of the capacity of the water cup 1, and the preset lower water level line is set to 10%-20% of the capacity of the water cup 1.

[0037] In a specific embodiment of the present invention, during use, condensate flows through the Y-shaped conical connector 3 into the water receiving cup 1 and gradually accumulates in the water receiving cup 1. When the water level sensor 25 detects that the condensate in the water receiving cup 1 has reached the preset upper water level line, the control circuit board 24 starts the micro water pump to automatically discharge the condensate in the water receiving cup 1 until the condensate in the water receiving cup 1 reaches the preset lower water level line, thus achieving automatic regulation of condensate in the breathing tubing. The automatic condensate regulation device for the breathing tubing can be used as an independent device. When there are other condensate collection devices in the breathing tubing, the water receiving cup 1 can be eliminated, and the puncture tube 23 can be directly inserted into the condensate collection device to achieve automatic regulation of condensate in the breathing tubing.

[0038] In a specific embodiment of the present invention, a piezoelectric ceramic plate is installed at the bottom of the water receiving cup 1. The resonant frequency shift is detected by the piezoelectric ceramic plate, and the viscoelastic characteristics of the condensate are inverted. Specifically, a piezoelectric ceramic disc (PZT) is adhered to the bottom of the water receiving cup 1. The piezoelectric inverse effect excites outward bending vibration of the ceramic surface to generate inherent resonance. The thin water film or accumulated water formed by condensation on the inner wall of the water receiving cup 1 adheres to the inner side of the bottom of the cup 1, and fluid-structure interaction occurs with the vibration interface, changing the equivalent mass, equivalent damping, and equivalent stiffness of the system, causing a resonant frequency shift and a decrease in the damping (quality factor) of the resonance peak. By using the frequency shift and damping dual parameters, combined with a viscoelastic fluid dynamics model, the shear viscosity, storage modulus (elasticity), loss modulus, relaxation time, and other viscoelastic characteristic parameters of the condensate are inverted. This identifies the degree of condensate contamination (distinguishing between clean condensate and bacterial condensate) and provides early warning of infection risks.

[0039] Real-time Example 2 like Figure 4 As shown, this application provides an automatic condensate regulation method for medical breathing tubing, the method comprising: Step S1: Real-time acquisition of environmental parameters, patient respiratory parameters, and tubing status parameters.

[0040] A feature data set is generated based on the collected environmental parameters, patient respiratory parameters, and tubing status parameters.

[0041] Patient respiratory parameters include: pulmonary function test data, oxygenation index data, sputum viscosity data, respiratory rate, tidal volume, etc.

[0042] Pipeline status parameters include: real-time pipeline liquid level, pipeline temperature, pipeline relative humidity, pipeline gas flow rate, humidifier temperature, etc.

[0043] Environmental characteristic parameters include atmospheric pressure, ambient temperature, and ambient air humidity.

[0044] For example, the generated feature dataset includes: ambient temperature and humidity, patient respiratory rate, tidal volume, humidifier temperature, and gas flow rate in the tubing.

[0045] Step S2: Based on the collected environmental parameters, patient respiratory parameters, and tubing status parameters, the predicted condensate level and condensate generation rate for a future time period are predicted using a pre-built condensate generation prediction model.

[0046] Step S2 includes: Step S210: Based on the collected environmental parameters, patient respiratory parameters, and tubing status parameters, the condensate generation rate is predicted using a pre-built condensate generation prediction model.

[0047] The formula for predicting the condensate formation rate is as follows: ; in, This indicates the predicted rate of condensate formation. Indicates the water vapor diffusion coefficient; Indicates the inner diameter of the condensate collection pipe; Indicates the flow amplification factor; This indicates the total air pressure inside the condensate collection pipe; This indicates the partial pressure of water vapor at the interface of the condensate collection pipe wall. This represents the gas constant of water vapor; Indicates the temperature of the condensate collection pipe; This represents the correction factor for non-equilibrium mass transfer resistance. This indicates the thickness of the condensate film on the inner wall of the condensate collection pipe; This represents the dynamic effective condensation length within the condensate collection pipe at time t. Represents the nuclear factor baseline constant; This represents the total number of categories of feature data; Indicates the first Weights of the feature data; Indicates the number of historical training samples; Indicates the first The reliability coefficient of a historical training sample; The value range is 0-1; Indicates the first Type of feature data The values ​​of each historical training sample; Indicates the current input model of the th Measured values ​​of various feature data; The width parameter represents the Gaussian radial basis function (RBF) kernel; || represents the norm. The kernel factor is the reference constant. For pipeline steady-state standard operating conditions, In the formula The summation is a fixed value obtained by substituting all parameters into the equation.

[0048] in, Re represents the Reynolds number, used to characterize the degree of turbulence in the airflow inside the condenser tube; Sc represents the Schmidt number, used to characterize the momentum and mass diffusion characteristics of the humid air system.

[0049] in, ; This represents the non-equilibrium hysteresis factor, a fixed constant calibrated by combining pipeline properties, condensate film characteristics, and CFD simulation and experimental data. This indicates the partial pressure of water vapor in the main flow zone inside the condenser tube; This indicates the partial pressure of water vapor at the interface of the condensate film on the condenser tube wall.

[0050] Among them, the characteristic data refers to the collected environmental parameters, patient respiratory parameters, and tubing status parameters.

[0051] As an example, sample τ=1: collected from the same type of ward and the same ventilator operating mode, the data is accurate, and the value A1 = 0.95 (high reliability); sample τ=2: collected from the emergency temporary ward, the ventilator parameters are very different, the data has low reference value, and the value A2 = 0.2 (low reliability).

[0052] This invention reproduces the nonlinear decay law of the entire condensation process in real pipelines, solving the inherent defects of traditional models that consistently overestimate predictions over long periods and allow errors to accumulate and diverge over time, thus achieving accurate prediction of the entire process over long time series. The condensate generation rate calculation method of this invention is adaptable to various condensation pipeline scenarios with different pipe diameters, materials, and operating environments, exhibiting a wide generalization range. Traditional mechanistic models cannot quantify and distinguish the differentiated contributions of multiple influencing features such as temperature, humidity, flow rate, and wall temperature to the condensation rate, treating all features uniformly; pure RBF models are easily interfered with by abnormal historical samples and noisy data, resulting in overfitting and prediction oscillations. This invention overcomes the shortcomings of pure mechanistic models in terms of insufficient prediction accuracy due to multi-factor coupling bias, and also solves the technical bottlenecks of traditional machine learning black-box models, such as lack of physical constraints, distortion in cross-condition extrapolation predictions, and lack of physical interpretability. It achieves a deep integration of the advantages of mechanistic interpretability and high-precision data fitting, a comprehensive effect that cannot be achieved by a single original model. The non-equilibrium mass transfer resistance correction term corrects the inherent assumption errors of the traditional equilibrium theory formula from the bottom up. Combined with adaptive compensation based on the patterns of multi-feature historical data, the relative prediction error is significantly reduced under various unsteady transient conditions such as pipeline start-up and shutdown, sudden changes in temperature and humidity, and fluctuations in airflow velocity. The stability of the whole process time series prediction is significantly better than that of existing technologies.

[0053] Step S220: Obtain the predicted condensate level based on the predicted condensate generation rate.

[0054] The formula for calculating the predicted condensate level is as follows: ; in, Indicates the predicted level of condensate; Indicates the liquid level at the current moment; Indicates the area of ​​the bottom of the water cup; Indicates the prediction time step (e.g., 5s, 10s). This indicates the predicted rate of condensate formation.

[0055] Step S3: Based on the predicted condensate level and condensate generation rate, the control unit controls the drainage execution unit to initiate the pre-drainage strategy.

[0056] Step S3 includes: Step S310: Compare whether the predicted liquid level of the condensate is greater than the preset upper limit value. If so, start the pre-drainage strategy and proceed to the next step. Otherwise, there is no need to start the pre-drainage strategy.

[0057] Step S320: Calculate the speed of the water pump controlled by the control unit based on the condensate generation rate.

[0058] The formula for calculating the pump speed controlled by the control unit is as follows: ; in, ; in, This indicates that the control unit controls the speed of the water pump; This is a sensitivity constant, representing the degree of sensitivity to the current error; express Time deviation value; This indicates the set desired liquid level height; express Real-time liquid level height measured by the liquid level sensor; Indicates the preset deviation threshold; is the confidence constant, representing the degree of confidence in the predicted compensation; This represents the predicted condensate formation rate, the condensate formation rate at the current moment predicted by the condensate formation prediction model (unit: mL / min or mm / s). This represents the viscosity adaptive compensation factor; This represents the estimated contamination level of the condensate at time t. Indicates the dynamic viscosity of pure water; This represents the effective dynamic viscosity of the condensate at time t (considering the actual viscosity after the sputum is mixed in); This indicates the reference compensation speed set according to the pump body characteristics. It is understood that the higher the sputum content in the condensate of this invention, the better. The larger the viscosity, the higher the pump speed, avoiding the risk of blockage caused by increased pump load due to increased condensate viscosity but unchanged speed.

[0059] This invention utilizes a piezoelectric ceramic sheet to excite a water cup to vibrate, collects the frequency shift and attenuation amplitude of the first, second, and third harmonics, and obtains an estimate of the pollution level by fusing the contributions of each harmonic through softmax.

[0060] The formula for calculating the pollution level estimate is as follows: ; in, This represents the normalized exponential function; Indicates the first The influence weight of subharmonic energy entropy; Indicates the first The frequency shift of the subharmonic; This indicates the resonant fundamental frequency (Hz) when the cup is empty. Indicates the first The amplitude of the second harmonic; This indicates the amplitude of the excitation signal when the cup is empty.

[0061] Different levels of contamination exhibit nonlinear selectivity in the attenuation of higher harmonics. Pure water primarily affects the fundamental frequency, while high-viscosity contaminated liquids significantly attenuate higher harmonics. In pure water, the energy attenuation of higher harmonics is small, while contaminated liquids containing sputum show significant attenuation of higher harmonics due to their viscoelastic properties. This allows for the differentiation between pure water, low-contamination, and high-contamination conditions, providing a reliable basis for adaptive compensation of pump speed.

[0062] Step S330: Control the water pump speed according to the calculated control unit and send a control command to the control unit.

[0063] In step S340, the control unit controls the water pump to rotate according to the control command.

[0064] Step S4: Adjust the temperature and humidity settings of the ventilator connected to the device according to the predicted condensate generation rate.

[0065] Step S4 includes: The predicted condensate generation rate is compared with the preset maximum rate limit. If the predicted condensate generation rate is greater than the preset maximum rate limit, the temperature and humidity level is determined and a temperature and humidity level adjustment command is sent to the ventilator; otherwise, no temperature and humidity level adjustment command is sent to the ventilator.

[0066] The methods for determining the temperature and humidity settings include: Step T1: Establish the mapping relationship between temperature and humidity regulation response parameters and temperature and humidity levels in advance.

[0067] Step T2: Calculate the temperature and humidity regulation response parameters based on the environmental impact index, patient body temperature, and pipeline gas flow rate.

[0068] The formula for calculating the temperature and humidity regulation response parameters is as follows: ; in, This indicates the temperature and humidity regulation response parameters; Indicates the environmental impact index; This indicates the deviation of the patient's body temperature from normal body temperature (assuming 37 degrees Celsius is considered normal). Indicates the real-time airflow rate within the pipeline; Indicates the reference ventilation flow rate; This indicates the predicted rate of condensate formation. This indicates the weight of the environmental impact index on the temperature and humidity regulation response parameters; This represents the weight of the effect of the deviation of the patient's body temperature from the normal body temperature (assuming 37 degrees Celsius is the normal body temperature) on the temperature and humidity regulation response parameters. This indicates the weight of the influence of real-time ventilation flow rate in the pipeline on the temperature and humidity regulation response parameters. This represents the weighting of the predicted condensate formation rate on the temperature and humidity regulation response parameters. Among them, .

[0069] in, ; in, Indicates the weight of the influence of ambient temperature; Indicates the weight of the influence of ambient humidity; Indicates ambient temperature; Indicates ambient humidity; Indicates the target pipeline temperature; Indicates the humidity of the target pipeline.

[0070] Step T3: Select the corresponding temperature and humidity setting based on the temperature and humidity adjustment response parameters and the mapping relationship between the temperature and humidity adjustment response parameters and the temperature and humidity settings.

[0071] Specifically, when the predicted condensate generation rate exceeds the preset maximum rate limit, the pipeline temperature is appropriately increased and the humidity is fine-tuned to reduce water vapor condensation within the pipeline. When the condensate generation rate is normal, the temperature and humidity settings are kept appropriate for the patient's respiratory status.

[0072] Step S5: Monitor abnormal condensate water characteristic data in real time. If abnormal condensate water characteristic data is obtained, an alarm is triggered; otherwise, no alarm is triggered.

[0073] Abnormal condensate water characteristics include: the measured liquid level in the receiving cup reaches 90% of the dynamic upper water level line; the condensate water generation rate exceeds the maximum drainage rate for 30 seconds; and the liquid level sensor detects a continuous rise in the liquid level in the receiving cup.

[0074] If the measured liquid level in the receiving cup reaches 90% of the dynamic upper water level line, an audible and visual warning will be issued, and the water pump speed will be automatically increased to the rated value. If the condensate generation rate exceeds the maximum drainage rate for 30 seconds, a high-frequency warning will be issued, and the ventilator will be activated to appropriately reduce the humidifier humidity to suppress condensate generation. When the liquid level sensor detects a continuous rise in the liquid level in the receiving cup (drainage failure), or a leak in the puncture tube / line, an emergency warning will be issued immediately, and the ventilator ventilation circuit will be automatically shut off to prevent condensate from flowing back into the patient's airway.
