Description

[0002] In the field of medical gas delivery (such as oxygen and anesthetic gases), maintaining a constant gas temperature is crucial for patient safety and treatment efficacy. Traditional medical gas heating systems often use a single heating element with a simple temperature control device, which has the following technical shortcomings: 1) Insufficient temperature control accuracy, making it difficult to cope with fluctuations in ambient temperature and changes in gas flow rate; 2) Rigid operating modes of the heating unit, either operating at full power leading to excessive energy consumption or insufficient power causing temperature fluctuations; 3) Continuous high-current operation easily causes aging of the heating element, shortening the equipment's lifespan; 4) Uneven heating of the pipeline can easily create localized high or low temperature areas, affecting gas quality. Although there are improved solutions using PID control algorithms in existing technologies, they have not effectively solved the dynamic thermal balance problem under multi-parameter coupling, especially exhibiting response lag when dealing with sudden changes in gas flow rate, making it difficult to meet the stringent requirements for gas temperature accuracy in scenarios such as intensive care and surgical anesthesia.

[0049] Further, the system further comprises a humidifying device as shown in Figure 3; wherein the humidifying device is used for humidifying and initially heating the gas.

[0050] The humidifying device comprises a plastic humidifying bottle 300 and a metal humidifying bottle 400, the plastic humidifying bottle 300 is located above the metal humidifying bottle 400, the bottom structure of the plastic humidifying bottle 300 is shown in Figure 4, and a plurality of round holes are arranged, the plastic humidifying bottle 300 is in communication with the metal humidifying bottle 400 through the plurality of round holes, when the gas enters the metal humidifying bottle 400, it enters the plastic humidifying bottle through the round holes, the plurality of round holes can increase the contact area of the gas and water, prolong the time of the gas in the metal humidifying bottle 400, and achieve the effect of sufficient humidification and heating; the material of the metal humidifying bottle 400 can be stainless steel or aluminum alloy, which can quickly conduct heat.

[0052] Further, the humidifying device further comprises a ring-shaped heater 500; the ring-shaped heater 500 is wrapped outside the metal humidifying bottle 400, and is used for initially heating the metal humidifying bottle 400; since the ring-shaped heater 500 is wrapped outside the metal humidifying bottle, it can better heat the metal humidifying bottle 400 and improve the heating efficiency.

[0053] Furthermore, the humidification device also includes a water inlet 800; the water inlet 800 is disposed on the top of the plastic humidification bottle and is used for water injection.

[0054] Furthermore, the temperature controller is used to perform the steps shown in Figure 5:

[0055] S100, acquire pipeline parameters G, gas parameters J, environmental parameters H, and the set gas temperature T. set .

[0056] In this embodiment, pipeline parameters include pipeline shape, pipeline cross-sectional area, pipeline thermal conductivity, etc.; gas parameters include gas type, gas flow rate, gas specific heat capacity, etc.; environmental parameters include air thermal conductivity, ambient temperature, ambient humidity, etc.; the set temperature is the gas temperature required by the user, for example, the oxygen temperature required for the user to inhale oxygen when the gas is oxygen.

[0057] S200, based on G, J, H and T set Determine the gas temperature in the pipeline to be maintained at T. set The required heat Q1 within a unit time period Δt.

[0058] In this embodiment, after obtaining a series of parameters, the gas in the pipeline is maintained at T. set The required heat per unit time can be obtained through theoretical calculations; however, theoretical calculations are based on ideal conditions, and there are deviations between ideal and actual conditions.

[0059] Furthermore, step S200 may include the following steps:

[0060] S210, based on G, J, H and T set Construct T set The corresponding target demand heat feature vector A = (G, J, H, T) set ); where G = (G1, G2, ..., G a , ..., G b ), a=1,2,…,b; G a Let J be the a-th pipeline parameter, and b be the number of pipeline parameters; J = (J1, J2, ..., J...) c , ..., J d ), c=1,2,…,d; J c Let d be the number of gas parameters, where c is the gas parameter and d is the number of gas parameters; H = (H1, H2, ..., H...) e H f ), e=1,2,…,f;H e Let f be the e-th environmental parameter, and f be the number of environmental parameters.

[0061] In this embodiment, after G, J, H and T set are obtained, the parameters in G, J and H and T set may be sequentially spliced to obtain A; it should be noted that some parameters in G, J and H may be type parameters, not numerical parameters, and such parameters can be one-hot encoded.

[0062] In S220, a preset standard demand heat characteristic vector list B=(B1, B2, …, B i , …, B n ) is obtained, i=1, 2, …, n; wherein B i is the ith preset standard demand heat characteristic vector, and n is the number of preset standard demand heat characteristic vectors; each standard demand heat characteristic vector corresponds to a demand heat.

[0063] In this embodiment, B can be obtained through a large number of experiments, that is, under different combinations of pipeline parameters, gas parameters, environmental parameters and set temperatures, the demand heat in a unit time period is measured, so as to obtain B.

[0064] In S230, the similarity between A and each standard demand heat characteristic vector in B is obtained to obtain a similarity list γ=(γ1, γ2, …, γ i , …, γ n ); wherein γ i is the similarity between A and B i .

[0065] In this embodiment, it should be noted that those skilled in the art can obtain the similarity between A and each standard demand heat characteristic vector in B according to actual needs using existing similarity determination methods, and details are not described herein.

[0066] In S240, a target similarity γ’=MAX(γ) is obtained; wherein MAX() is a preset maximum value function.

[0067] In S250, the demand heat corresponding to γ’ is determined as Q1.

[0068] In this embodiment, the gas delivery overall environment corresponding to the maximum similarity is most similar to the current gas delivery environment, so the demand heat corresponding to γ’ can be determined as Q1; this method is based on actually measured data, and has higher accuracy compared with theoretical calculation.

[0069] In S300, the number NUM of heating jackets to be started is determined according to Q1, the maximum heat conduction coefficient η max of the heating jacket and the working current I1 corresponding to η max .

[0070] Further, NUM=Q1 / (I1 2 ×R×η max ×Δt).

[0071] In the embodiment, it can be understood that there is a corresponding maximum heat transfer coefficient for the heating jacket, in order to improve the heating efficiency, it is necessary to control the heating jacket to work in the state of the maximum heat transfer coefficient, therefore, for different heat demand, it is necessary to control the start of different number of heating jackets.

[0072] S400, control the pipeline heating device to start NUM heating jackets.

[0073] In the embodiment, each heating jacket is provided with an independent control switch, and the connection and disconnection of the heating jacket can be controlled through the control switch.

[0074] Further, the NUM heating jackets are uniformly selected according to the arrangement order, so that the heating is more uniform, and at the same time, the working time of each heating jacket can be balanced, and the service life is improved.

[0075] S500, according to the gas conveying flow rate parameter in the pipeline, control the working current of the pipeline heating device.

[0076] Further, step S500 can include the following steps:

[0077] S510, if the gas in the pipeline is constant flow rate, then the working current of the pipeline heating device is controlled to be I z =NUM×I1 / (1-α); wherein, α is the power loss rate of the heating device.

[0078] In the embodiment, if the gas in the pipeline is constant flow rate, then the heating device can be controlled to continuously heat, so that the gas in the pipeline is kept at constant temperature.

[0079] Further, step S500 can also include the following steps:

[0080] S520, if the gas in the pipeline is oxygen for user breathing, then the oxygen inhalation time period time sequence list T=(T1, T2, …, T p , …, T q ) of the user in the preset historical time period is obtained, p=1, 2, …, q; wherein, T p is the pth oxygen inhalation time period of the user in the preset historical time period, q is the number of oxygen inhalation time periods of the user in the preset historical time period; the end time of the preset historical time period is the current time.

[0081] In this embodiment, the user inhales oxygen, not continuously, but at a certain frequency, that is, inhales for a period of time and stops for a period of time; the control system of the breathing machine can obtain the oxygen inhalation time sequence list T of the user in the preset historical time period; the preset historical time period can be 1 min, or set according to actual needs.

[0082] S530, according to T, determine the corresponding oxygen inhalation interval length list TY= (TY1, TY2, …, TY of the user in the preset historical time period r , …, TY q-1 ), r=1, 2, …, q-1; wherein TY r is the rth oxygen inhalation interval length of the user in the preset historical time period; TY r =TK r+1 -TJ r ; TK r+1 is the start time corresponding to T r+1 , TJ r is the end time corresponding to T r .

[0083] S540, according to TY, determine the corresponding average oxygen inhalation interval length TU=∑ q-1 r=1 TY r .

[0084] In this embodiment, the oxygen inhalation interval length corresponding to users of different constitutions is different, and the oxygen inhalation interval length of the same user in different time periods is also different, and through the above steps, the oxygen inhalation interval length of the user can be obtained in real time and dynamically.

[0085] S550, obtain the heating lag length TQ corresponding to the heating device.

[0086] In this embodiment, it can be understood that for temperature control, there is a certain hysteresis, that is, the heating device needs a period of time to heat after the working current is input, and the heating lag length TQ corresponding to the heating device can be obtained through a large number of tests.

[0087] S560, whenever the user oxygen inhalation end time point is reached, the heating device of the pipeline is controlled to input the working current I z after an interval of TU-TQ.

[0088] In this embodiment, when the user oxygen inhalation end time point is reached, the heating device of the pipeline is controlled to input the working current I zThat is, the heating device is controlled to enter the working state in advance, so that when the user starts to inhale oxygen, the heating state is just good, the heating peak is matched with the oxygen inhalation time period of the user, and the best heating effect is achieved, and meanwhile, the electric energy is saved.

[0089] In some embodiments, the gas in the pipeline can also be a liquid. When it is a liquid, it can be applied to the scene of user infusion. It should be noted that when the gas in the pipeline is changed into a liquid, the collected gas parameters also need to be changed into corresponding liquid parameters, and the calculation of the heating lag also needs to be changed to correspond to the liquid. The subsequent calculation process and control method are the same as those of the gas, and details are not repeated here. Whether the medium in the pipeline is a gas or a liquid, it falls within the protection scope of the present application.

[0090] In the embodiment, the pipeline parameters (G), the gas parameters (J), the environmental parameters (H) and the target temperature (T set ) are comprehensively calculated to establish a multi-dimensional thermodynamic model to accurately calculate the required heat Q1; the required heat is intelligently distributed to the number of heating jackets (NUM) based on the maximum heat transfer coefficient η max , and the load balancing is performed with the corresponding current I1, so that the energy consumption can be effectively reduced under the same working condition, and the heating element is prevented from being overloaded and damaged; the working current is dynamically adjusted by real-time monitoring of the gas delivery flow rate, so that power compensation is completed in a short time when the flow rate suddenly changes, and the temperature deviation is small when the flow rate fluctuates; the structure design of the multiple heating jackets which are uniformly distributed along the circumference of the pipeline, in combination with the time-sharing and partition control strategy, makes the temperature gradient of the pipeline wall small, and completely eliminates the "yin and yang surface" phenomenon caused by the traditional single-sided heating; the distributed heating jacket rotation work mode is adopted, compared with the centralized heating device, the daily average working time of a single heating jacket is greatly reduced, and the service life of the system is improved; so as to meet the strict requirements of the scene of intensive care, surgical anesthesia and the like on the temperature accuracy of the gas.

[0091] In addition, although the various steps of the methods in the present disclosure are described in a particular order in the accompanying drawings, this does not require or imply that the steps must be performed in this particular order, or that all of the steps shown must be performed to achieve the desired results.
