Description

Technical Field

[0001] This invention relates to the field of maternal and infant products, specifically to a method for controlling the milk flow initiation of a breast pump and related equipment. Background Technology

[0002] The lactation initiation phase (also known as lactation stage II or mammary gland activation phase) usually occurs around 48-72 hours postpartum (about 2-3 days). The key sign is that the breasts, which were soft and secreting a small amount of colostrum, suddenly become full, warm, heavy, and may even show obvious physiological breast engorgement. At this time, the amount of milk increases significantly, and the color gradually changes from the pale yellow of colostrum to the white of transitional milk.

[0003] Studies have shown that a mother's ability to maintain sufficient milk supply during lactation stage III (approximately 9 days postpartum to the involution stage) depends on the activation of the breasts during lactation stage II. Failure to enter lactation stage II normally may lead to insufficient milk supply during subsequent lactation stage III, making it difficult to feed the baby normally.

[0004] In the early postpartum period, mothers typically have low milk production and need their babies to suckle to help them transition from lactation stage I to lactation stage II. However, if mothers and babies are separated or the baby's suckling is weak, mothers may not be able to transition to lactation stage II normally, which can negatively impact their ability to produce enough milk later on. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a method that can better help mothers enter the lactation initiation period.

[0020] Optionally, determining the negative pressure intensity applied by the negative pressure mechanism in the lactation start mode based on the operating position of the breast pump when the third instruction is received includes: using the negative pressure intensity of the negative pressure mechanism corresponding to the operating position of the breast pump when the third instruction is received as the negative pressure intensity of the lactation start mode; or, determining a first operating position of the breast pump when the third instruction is received, determining a second operating position one level weaker than the first operating position, and using the negative pressure intensity of the negative pressure mechanism corresponding to the second operating position as the negative pressure intensity of the lactation start mode.

[0021] Optionally, the method further includes: when exiting the lactation initiation mode, determining the total amount of milk secreted by the user during the entire process of the lactation initiation mode; and if the total amount of milk meets a preset condition, canceling the association between the first instruction and the lactation initiation mode so that the lactation initiation mode will not be entered again when the first instruction is received again.

[0022] Optionally, determining the total amount of milk secreted by the user during the entire process of the lactation initiation mode when exiting the lactation initiation mode includes: determining the first total amount of milk and the second total amount of milk secreted by the breast pumps used on the user's left and right breasts during the entire process of the lactation initiation mode when exiting the lactation initiation mode; and determining the third total amount of milk based on the first total amount of milk and the second total amount of milk.

[0037] 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 embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] 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.

[0039] The lactation start control method for a breast pump provided in this application embodiment can be applied to a breast pump, or to a mobile terminal (such as a mobile phone, tablet computer, smartwatch, etc.) or server that is connected to the breast pump.

[0040] The following is an introduction to the general structure of breast pumps.

[0041] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a breast pump provided in an embodiment of this application. Figure 1 As shown, the breast pump includes a shell 1, a milk storage container 2, a negative pressure mechanism 3, and a breast shield 4.

[0042] Among them, the milk storage container 2 is used to store the milk expressed by the breast pump, the negative pressure mechanism 3 is used to create negative pressure to extract the milk, and the breast shield 4 is used to cover the human breast and provide a milk flow channel.

[0043] Optionally, the milk storage container 2 may take the form of a milk cap, milk bowl, milk bottle, etc., and this application does not impose any restrictions.

[0044] Optionally, the breast pump may also include a power supply module, such as a battery, which provides power to the negative pressure mechanism 3 to support its operation.

[0045] Optionally, the breast shield 4 includes a breast suction channel and a flange. The breast suction channel is used to accommodate the nipple and provide a milk flow channel for milk to flow, thereby allowing the milk to enter the milk storage container 2. The flange is used to cover the human breast and fit the human breast.

[0046] Optionally, the breast pump channel and flange are integrally molded, or the breast pump channel and flange are detachably sealed together. Integral molding of the breast pump channel and flange improves structural stability; the detachable design of the breast pump channel and flange facilitates cleaning and replacement of parts, adapting to the needs of different users.

[0047] Optionally, the negative pressure mechanism 3 in the breast pump 1 that generates negative pressure can be directly connected to cause negative pressure inside the breast pump shield, or it can indirectly cause negative pressure inside the breast pump shield by transmitting negative pressure to a diaphragm assembly or a liquid barrier such as an airbag; the negative pressure mechanism 3 introduces breast milk into the milk storage container 2 for storage through negative pressure.

[0048] in, Figure 1 An example of how the breast pump 1 transmits negative pressure to the diaphragm assembly, indirectly causing negative pressure inside the breast shield 4.

[0049] Optionally, the negative pressure mechanism includes one of a negative pressure pump drive mechanism, a magnetic drive mechanism, or a mechanical drive mechanism.

[0050] The following example illustrates how different types of negative pressure mechanisms can induce negative pressure, using the negative pressure mechanism 3 as an example of how it transmits negative pressure to the diaphragm assembly to indirectly cause negative pressure inside the breast suction shield.

[0051] In one possible implementation, the negative pressure mechanism 3 is a negative pressure pump drive mechanism. The negative pressure pump includes, but is not limited to, piezoelectric pumps, diaphragm pumps, hydraulic pumps, mechanical pumps, etc. The negative pressure pump causes the diaphragm assembly to deform by drawing air from the negative pressure chamber, thereby creating negative pressure inside the breast suction shield.

[0052] In another possible implementation, the negative pressure mechanism is a magnetic drive mechanism, including a first magnetic element and a second magnetic element. The diaphragm assembly includes a deformable portion and a flexible portion, forming a negative pressure chamber between the deformable portion and the flexible portion. The second magnetic element is disposed in the flexible portion of the diaphragm assembly, and the first and second magnetic elements are arranged opposite to each other. When the control mechanism controls the first magnetic element to be energized, the first magnetic element drives the second magnetic element to move through magnetic force. The movement of the second magnetic element causes the flexible portion to deform, resulting in negative pressure inside the breast suction shield.

[0053] In another possible implementation, the negative pressure mechanism is a mechanically driven mechanism employing a piston, including a piston assembly comprising a screw and a piston. The diaphragm assembly includes a deformable portion and a flexible portion, forming a negative pressure chamber between the deformable and flexible portions. The piston is connected to the flexible portion, and when the control mechanism moves the piston by controlling the screw, the piston movement causes the flexible portion to deform, resulting in negative pressure inside the breast shield.

[0054] Optionally, the breast pump includes a control mechanism and at least one sensor. The at least one sensor is used to acquire data required to execute the lactation start control method of the breast pump of this application. The control mechanism is used to execute the lactation start control method of the breast pump of this application based on the data, or to send the data to an external electronic device connected in communication, so that the external electronic device can execute the lactation start control method of the breast pump of this application.

[0055] Optionally, the control mechanism may include a central processing unit (CPU), a micro controller unit (MCU), etc.

[0056] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a method for controlling the lactation initiation of a breast pump according to an embodiment of this application. Figure 2 As shown, the control method 100 includes steps 110 to 130.

[0057] Step 110: In response to the first command to enter the lactation start mode, control the negative pressure mechanism of the breast pump to work at a preset working frequency.

[0058] In one possible implementation, the first instruction is generated by a physical button on the breast pump.

[0059] In another possible implementation, the first instruction is generated by a mobile terminal or remote control that communicates with the breast pump.

[0060] Since the time from childbirth to lactation initiation typically only takes 3-5 days, the lactation initiation mode is time-limited. Once the mother enters the lactation initiation period, she can stop using the lactation initiation mode and switch to regular breast pumping. Therefore, a dedicated button for the lactation initiation mode is not necessary; instead, the existing button on the breast pump can be used to trigger it. Optionally, the first instruction can be generated by a universal button on the breast pump.

[0061] Therefore, there is no need to add a separate physical / virtual button on the breast pump or its accompanying mobile app to enter the lactation start mode.

[0062] Please see Figure 3 , Figure 3 This is another structural schematic diagram of the breast pump provided in the embodiments of this application. For example... Figure 3 As shown, breast pumps typically include a power button (5), a mode switch button (6), a speed + button (7), and a speed - button (8). The first command can be triggered by any of these buttons. Of course, if the breast pump includes... Figure 3 Other keys that are not present in the key can also be triggered by other keys.

[0063] Optionally, the first instruction is triggered by the power button 5 or the virtual control on the mobile APP to turn on the breast pump. The user clicks the power button 5 or the virtual control to turn on the breast pump. After turning on, the breast pump will automatically enter the lactation start mode and work in the lactation start mode.

[0064] Of course, a dedicated start button can also be set for the lactation start mode. Based on this, the first instruction can optionally be a dedicated instruction to enter the lactation start mode. For example, the breast pump may include a dedicated lactation start mode button, and the first instruction may be generated by the dedicated lactation start mode button. Alternatively, when the mode switching button is triggered, the breast pump can be switched to the lactation start mode. Or, for example, there may be a dedicated virtual control on the mobile app for entering the lactation start mode, and the user can click on the virtual control to start the lactation start mode.

[0065] Step 120: Obtain the milk flow rate parameters in the milk suction channel.

[0066] Optionally, the flow sensor for measuring flow rate is located inside the breast pumping channel. The flow sensor is one of the following: capacitive sensor, photoelectric sensor, ultrasonic sensor, calorimetric sensor, or pressure sensor.

[0067] In related technologies, some breast pumps have a lactation initiation mode. However, these technologies mainly rely on preset time, stimulation frequency, and negative pressure mode, attempting to induce lactation through a fixed stimulation-pumping-pause cycle. For each mother, the stimulation process is the same, focusing only on simulating the baby's sucking but neglecting the effectiveness of the simulation. In this application, the lactation initiation mode is controlled by milk flow parameters. The pumping rhythm can be adjusted individually according to each mother's lactation initiation process and milk flow rate, reducing inappropriate stimulation of the mammary glands and improving the lactation initiation effect.

[0068] Step 130: Using the preset working frequency as the initial value, adjust the working frequency of the negative pressure mechanism in a negative correlation according to the changing trend of the milk flow rate parameter.

[0069] Specifically, negative correlation means that the value of the dependent variable decreases (increases) as the value of the independent variable increases (decreases). In this case, the correlation coefficient between the dependent and independent variables is negative.

[0070] Therefore, the negative correlation adjustment of the operating frequency of the negative pressure mechanism based on the changing trend of the milk flow rate parameter in step 130 specifically involves: Step 131: When the milk flow rate parameter shows an upward trend, reduce the operating frequency of the negative pressure mechanism.

[0071] Step 132: When the milk flow rate parameter shows a downward trend, increase the operating frequency of the negative pressure mechanism.

[0072] By using negative correlation adjustment, the working frequency of the negative pressure mechanism in the lactation initiation mode of this application is dynamically adjusted according to the amount of milk secreted by the mother, thereby better simulating the actual sucking process of the baby and effectively improving the effectiveness of lactation initiation.

[0073] Optionally, the milk flow rate parameter includes the flow rate change rate, i.e., the first derivative of the flow rate. When the flow rate change rate is greater than zero, the change trend of the milk flow rate parameter is determined to be an upward trend; when the flow rate change rate is less than zero, the change trend of the milk flow rate parameter is determined to be a downward trend.

[0074] Infant sucking can be categorized into nutrient sucking and non-nutrient sucking. Nutrient sucking refers to the sucking action performed by the infant to obtain milk, while non-nutrient sucking refers to the sucking behavior performed solely to satisfy the infant's need to suckle when there is no milk flowing into their mouth. Simply put, non-nutrient sucking is "empty sucking"—there is the sucking motion, but no milk is swallowed.

[0075] Non-nutritive sucking is usually fast and shallow, while nutritive sucking is usually slow and deep. Therefore, the above steps mean that if the flow rate is increasing, that is, the mother is accelerating milk secretion, the working frequency of the negative pressure mechanism is reduced to simulate the infant's nutritive sucking; if the flow rate is decreasing, that is, the mother's milk secretion rate is decreasing, the working frequency of the negative pressure mechanism is increased to simulate the infant's non-nutritive sucking. Thus, the working frequency of the negative pressure mechanism is adjusted in real time according to the flow rate, simulating the infant's actual sucking process.

[0076] In this application, the working frequency of the negative pressure mechanism is adjusted in real time according to the rate of change of flow rate. However, when the mother's milk secretion rate does not increase continuously, the negative pressure frequency cannot rise indefinitely, otherwise it will exceed the limit of the pump and cause breast pain. When the mother's milk secretion rate continues to increase, the negative pressure frequency cannot be reduced to zero, as reducing it to zero does not conform to the baby's sucking pattern.

[0077] Therefore, optionally, the present application imposes restrictions on the highest and lowest operating frequencies of the negative pressure mechanism, such that the highest operating frequency of the negative pressure mechanism is in a first frequency range, the lowest operating frequency of the negative pressure mechanism is in a second frequency range, and the lower limit of the first frequency range is greater than the upper limit of the second frequency range.

[0078] Optionally, the first frequency range is [100cpm, 130cpm], thereby ensuring that milk secretion is promoted without causing breast pain.

[0079] Optionally, the preset operating frequency is within the first frequency range. That is, in the initial stage of the lactation initiation mode, it simulates the non-nutritive sucking of an infant.

[0080] Optionally, the second frequency range is [40 cpm, 70 cpm], thereby ensuring continuous and effective breast milk expression.

[0081] The following section explains how to adjust the operating frequency of the negative pressure mechanism.

[0082] Optionally, the operating frequency of the negative pressure mechanism can be adjusted in fixed steps. When the milk flow rate parameter is on an upward trend, the decreasing step size of the operating frequency of the negative pressure mechanism can be the same as or different from the increasing step size of the operating frequency of the negative pressure mechanism when the milk flow rate parameter is on a downward trend.

[0083] For example, for every 1 second that the milk flow rate parameter maintains an upward trend, the operating frequency of the negative pressure mechanism decreases by 0.5 cpm; for every 1 second that the milk flow rate parameter maintains a downward trend, the operating frequency of the negative pressure mechanism increases by 0.5 cpm, thereby adjusting the operating frequency of the negative pressure mechanism with a fixed step size.

[0084] Optionally, the operating frequency of the negative pressure mechanism can be adjusted using a preset formula. When the milk flow rate parameter is on an upward trend, the operating frequency of the negative pressure mechanism is adjusted using a first adjustment formula; when the milk flow rate parameter is on a downward trend, the operating frequency of the negative pressure mechanism is adjusted using a second adjustment formula.

[0085] Optionally, the output of the preset formula includes the change in the working frequency of the negative pressure mechanism or the specific value of the working frequency, and the input includes the trend holding time of the milk flow rate parameter.

[0086] Therefore, according to the preset formula, the rate of change of the working frequency of the negative pressure mechanism is controlled, and the adjustment can be made in any customized way, such as fast first and then slow, fast first and then slow, or other arbitrary methods. This application does not limit the specific content of the formula, and the first adjustment formula can be the same as or different from the second adjustment formula.

[0087] Optionally, the time required for the working frequency of the negative pressure mechanism to change is limited. When the milk flow rate parameter continues to decrease, the time required for the working frequency of the negative pressure mechanism to rise from the lowest working frequency to the highest working frequency is within the range of [8S, 30S]; when the milk flow rate parameter continues to increase, the time required for the working frequency of the negative pressure mechanism to decrease from the highest working frequency to the lowest working frequency is within the range of [8S, 30S].

[0088] For example, upon receiving the first instruction to start the lactation mode, the negative pressure mechanism operates at a preset working frequency, such as 110 cpm as the initial value. If the milk flow rate parameter continues to rise after entering the lactation mode, the negative pressure frequency of the negative pressure mechanism will decrease to the lowest working frequency, such as 50 cpm, within 8-30 seconds, and then remain at 50 cpm until the milk flow rate parameter changes from an upward trend to a downward trend.

[0089] To ensure effective lactation initiation, the operating frequency of the negative pressure mechanism cannot change too quickly or too slowly. This application constrains the average rate of frequency change of the negative pressure mechanism by limiting the time between the lowest and highest operating frequencies, thereby ensuring effective lactation initiation. Furthermore, unlike the concept of mode switching in related technologies, the operating frequency of the negative pressure mechanism in this application changes in real time according to the rate of flow change within the range of the highest and lowest operating frequencies, and the operating frequency of the negative pressure mechanism no longer changes abruptly with mode switching.

[0090] Furthermore, when the first instruction is generated by a general key press, after the mother successfully enters the lactation initiation phase, it is necessary to cancel the association between the first instruction and the lactation initiation mode. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is another schematic flowchart of the lactation start control method for the breast pump provided in this application embodiment. For example... Figure 4 As shown, the lactation start control method 100 for the breast pump provided in this application includes steps 140 to 150 in addition to steps 110 to 130.

[0091] Step 140: When exiting the lactation initiation mode, determine the total amount of milk secreted by the user throughout the entire lactation initiation mode.

[0092] The total amount of milk secreted during the entire lactation initiation mode can be measured by a milk volume sensor or flow sensor in the milk storage container. The milk volume sensor includes a liquid level sensor, a weight sensor, etc., which have been described in the upper part of the instruction manual and will not be repeated here.

[0093] Step 150: If the total milk volume meets the preset conditions, cancel the association between the first instruction and the lactation initiation mode so that the lactation initiation mode will not be entered again when the first instruction is received.

[0094] The above methods can reduce ineffective stimulation. If lactation initiation has been successful, the breast pump will stop the lactation initiation program and switch to the regular pumping program for efficient milk expression, thus avoiding continued meaningless stimulation.

[0095] For example, a user account is logged into the mobile app that communicates with the breast pump. When the user's milk expression records and / or the personal information entered by the user indicate that the user is in the lactation stage I after childbirth, the breast pump automatically enters the lactation start mode after being turned on. If the total amount of milk expressed is greater than 20ml for three consecutive days, it is determined that the user has entered the lactation start period. After that, the breast pump will no longer enter the lactation start mode when turned on, but will instead enter the normal milk expression mode. That is, when the user first uses the breast pump, pressing the power button will enter the lactation start mode, and after the user enters the lactation start period, pressing the power button will change to enter the normal milk expression mode. Optionally, if the user uses a breast pump to express milk from each of their left and right breasts, then step 140 includes steps 141 to 142.

[0096] Step 141: Determine the first total milk volume and the second total milk volume secreted during the entire process of the lactation activation mode when the breast pumps used on the user's left and right breasts exit the lactation activation mode.

[0097] Optionally, the mobile terminal is simultaneously connected to breast pumps used on the left and right breasts respectively. When the breast pumps used on the left and right breasts exit the lactation activation mode, the mobile terminal receives the first total milk volume and the second total milk volume sent by the two breast pumps.

[0098] Optionally, the duration of the lactation initiation mode is [10 min, 20 min], and the lactation initiation mode will automatically exit after the duration is reached.

[0099] Optionally, if the mother is still secreting colostrum after the time limit has been reached (e.g., the flow rate is greater than zero), the lactation initiation mode continues until the mother stops secreting.

[0100] Step 142: Determine the third total milk volume based on the first total milk volume and the second total milk volume.

[0101] At this time, the preset conditions in step 150 include: when the lactation start mode is exited multiple times or for multiple days, the total amount of the third milk is greater than a preset threshold.

[0102] Optionally, the preset threshold is within the range of [10ml, 30ml].

[0103] It is understood that the preset threshold value is related to the duration of the lactation initiation mode, and can be selected according to the actual situation; this application does not impose any restrictions. For example, the duration of the lactation initiation mode is approximately 15 minutes, and the preset threshold is 20 ml.

[0104] Optionally, if the user uses only one breast pump to express milk, the preset threshold will be reduced accordingly, for example, the preset threshold will be in the range of [5ml, 15ml].

[0105] The above method can intelligently determine whether a user has entered the lactation initiation period through preset conditions. Once the lactation initiation period has been entered, the lactation initiation mode will not be automatically activated, thus improving the intelligence level of the breast pump.

[0106] Alternatively, if the breast pump is controlled by a PWM signal, the operating frequency of the negative pressure mechanism can be adjusted by controlling the frequency of the PWM signal.

[0107] Optionally, in order to improve the comfort and efficiency of the lactation initiation mode and prevent pain from affecting colostrum secretion, the lactation initiation mode of this application further includes: adjusting the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the milk suction channel at least for a portion of the time.

[0108] In the lactation start mode, the breast pump continuously performs suction cycles. Each suction cycle includes an air intake process (a negative pressure is formed in the milk suction channel until the negative pressure peak is reached), a pause process (the negative pressure peak is maintained), and an air release / intake process (the negative pressure in the milk suction channel disappears and gradually recovers from the negative pressure peak to atmospheric pressure). Therefore, "partial time" refers to the fact that in the lactation start mode, at least in at least one of the air intake and pause processes, the negative pressure intensity applied by the negative pressure mechanism is adjusted according to the negative pressure intensity in the milk suction channel.

[0109] Optionally, the negative pressure mechanism does not apply negative pressure during the venting / intake process, so it is not necessary to adjust the intensity of the negative pressure applied by the negative pressure mechanism during the venting / intake process.

[0110] Optionally, adjusting the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the breast pump channel includes the following steps: (1) Obtain the flow rate in the breast pumping channel.

[0111] (2) Determine the negative pressure intensity in the milk suction channel based on the flow rate.

[0112] Optionally, step (2) specifically involves: determining the volume of milk extracted based on the flow rate; and determining the negative pressure intensity in the milk extraction channel based on the volume.

[0113] Optionally, the specific formula for determining the negative pressure intensity in the breast pumping channel based on the volume is as follows;

[0114] Where n is the amount of substance, R is the ideal gas constant, and T is the thermodynamic temperature of the gas. It refers to the volume of the closed chamber in the milk suction channel where negative pressure exists when negative pressure is formed. This represents the total amount of milk extracted during the current pumping cycle.

[0115] in, The specific formula is as follows:

[0116] in, The start time of the current suction cycle. For the current time, and The difference is the duration of the current suction cycle, and Q(t) is the flow rate.

[0117] Optionally, n, R, T and Both are preset values, although n and There may be some errors depending on the actual situation. For example, different users have different breast sizes, which occupy different volumes in the breast suction channel. This leads to differences in the volume of the closed chamber with negative pressure in the breast suction channel when negative pressure is finally formed. However, in reality, the above errors can be ignored, or a correction coefficient can be formed based on factors such as the user's breast size, and the preset n and The specific modifications can be made as needed, and this application does not impose any restrictions.

[0118] (3) Adjust the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the milk suction channel.

[0119] The negative pressure intensity applied by the negative pressure mechanism is adjusted according to the negative pressure intensity in the milk suction channel to maintain the negative pressure intensity in the milk suction channel near the reference negative pressure intensity.

[0120] When the negative pressure intensity applied by the negative pressure mechanism is constant, the more breast milk is expressed, the larger the volume occupied by the breast milk, which will cause the negative pressure intensity in the milk suction channel to increase, causing it to deviate from the reference negative pressure intensity. The above method calculates the negative pressure intensity in the milk suction channel through flow rate, and adjusts the negative pressure intensity of the negative pressure mechanism according to the negative pressure intensity in the milk suction channel. The more milk is expressed, the lower the negative pressure intensity applied by the negative pressure mechanism is, so as to ensure that the negative pressure in the milk suction channel (i.e. the negative pressure felt by the human breast) is basically constant near the reference negative pressure intensity, thus ensuring the comfort of breastfeeding.

[0121] Optionally, adjusting the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the breast pump channel includes the following steps: (1) Obtain the negative pressure intensity detected by the pressure sensor in the breast suction channel.

[0122] (2) Adjust the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the milk suction channel.

[0123] The above method uses a pressure sensor to detect the negative pressure intensity, resulting in more accurate results.

[0124] In one possible implementation, after obtaining the negative pressure intensity in the breast pumping channel, control is performed using a PID control algorithm based on the difference between the negative pressure intensity in the breast pumping channel and the reference negative pressure intensity.

[0125] It is understood that, in addition to the PID algorithm, fuzzy logic control, adaptive control, and other algorithms can also be used, and this application does not impose any restrictions.

[0126] In another possible implementation, after obtaining the negative pressure intensity in the breast suction channel, the negative pressure intensity applied by the negative pressure mechanism is adjusted according to the difference between the negative pressure intensity in the breast suction channel and the reference negative pressure intensity, through a preset mapping relationship between the difference and the negative pressure intensity.

[0127] Optionally, if the control signal of the negative pressure mechanism is a PWM signal, adjusting the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the breast pumping channel includes: adjusting the duty cycle of the PWM signal input to the negative pressure mechanism according to the negative pressure intensity in the breast pumping channel.

[0128] As explained earlier, the more breast milk is expressed, the larger the volume occupied by the breast milk, which leads to an increase in the negative pressure intensity in the milk suction channel. The larger the duty cycle, the greater the negative pressure intensity applied by the negative pressure mechanism. Therefore, the negative pressure intensity in the milk suction channel is inversely proportional to the duty cycle.

[0129] Optionally, before entering the lactation initiation mode, the user needs to select an appropriate negative pressure intensity as the reference negative pressure intensity for the lactation initiation mode. In this case, the control method 100 provided in this application further includes steps 160 to 180.

[0130] Step 160: In response to the second command, control the breast pump to start working at the lowest operating level.

[0131] The triggering method for the second command is similar to that for the first command. For example, both can be triggered by physical buttons on the breast pump, virtual controls on the mobile app, or physical buttons on the breast pump remote control. These details will not be elaborated here.

[0132] Optionally, the trigger button for the second instruction is the same as the trigger button for the first instruction, for example, the trigger button is the power button.

[0133] Optionally, the trigger button for the second instruction is different from the trigger button for the first instruction; the second instruction has a dedicated trigger button.

[0134] For example, if both the second instruction and the first instruction are triggered by the power button, then the second instruction and the first instruction can be the same instruction in the program. The control mechanism of the breast pump enters different programs according to the number of times the first instruction is triggered. After the power button is triggered for the first time, the reference negative pressure intensity calibration program is entered to allow the user to determine the most comfortable negative pressure intensity. Subsequent triggering of the power button enters the lactation start program. After it is determined that the user has started lactation, the association between the first instruction and the lactation start mode is canceled, and triggering the power button no longer enters the lactation start program but enters the normal lactation program.

[0135] Step 170: Gradually increase the operating level of the breast pump.

[0136] For example, the gear position is increased by one level every 3-5 seconds or every 8-12 seconds. This application does not limit the time required to increase the gear position.

[0137] Step 180: In response to a third instruction input by the user, determine the negative pressure intensity applied by the negative pressure mechanism in the lactation start mode based on the working setting of the breast pump when the third instruction is received.

[0138] Optionally, the third command is generated by the gear selector button on the breast pump. It is understood that the third command can also be triggered by other buttons, such as the gear selector button or the mode switch button, etc., and this application does not impose any restrictions.

[0139] Optionally, step 180 includes: taking the negative pressure intensity of the negative pressure mechanism corresponding to the working position of the breast pump when the third instruction is received as the negative pressure intensity of the lactation start mode; or, determining the first working position of the breast pump when the third instruction is received, determining a second working position one level weaker than the first working position, and taking the negative pressure intensity of the negative pressure mechanism corresponding to the second working position as the negative pressure intensity of the lactation start mode.

[0140] For example, when the user presses the gear- button, the breast pump operates at the third gear. The negative pressure intensity corresponding to the third gear is then determined as the negative pressure intensity of the lactation start mode. For instance, the duty cycle of the PWM signal corresponding to the third gear is determined as the duty cycle of the PWM signal of the lactation start mode.

[0141] For example, when the user presses the gear- button, the breast pump operates at the third gear. The negative pressure intensity corresponding to the second gear, which is one level lower, is then determined as the negative pressure intensity of the lactation start mode. For instance, the duty cycle of the PWM signal corresponding to the second gear is determined as the duty cycle of the PWM signal of the lactation start mode.

[0142] The above method operates according to the most suitable negative pressure intensity determined by the user when entering the lactation activation mode, preventing breast pain and other problems caused by the lactation activation mode. In addition, the step of adjusting the negative pressure intensity applied by the negative pressure mechanism according to the negative pressure intensity in the milk suction channel can ensure that the negative pressure in the milk suction channel is always within the user's comfortable range, further improving the user's comfort. In turn, the user's pleasant mood is also conducive to promoting lactation.
