Description

Technical Field

[0001] The present invention relates to the field of maternal and infant products, and in particular to a method and device for detecting the amount of milk in a breast pump, a breast pump and a storage medium. Background Art

[0002] A breast pump is usually provided with a milk volume sensor for measuring the amount of milk. Measuring the amount of milk can prevent the breast pump from overflowing and can also allow the user to determine whether the amount of milk stored in the current milk storage container is sufficient.

[0003] However, the breast pump needs to be worn by the user when in use. When the user moves, such as walking, standing up, or sitting down, the stored milk will shake, causing a series of phenomena such as "milk hanging on the wall" and "liquid surface tilting", which can easily cause the detection value of the milk amount sensor to be wrong.

[0004] Therefore, how to improve the accuracy of milk volume measurement is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present application is to improve the accuracy of milk volume measurement of a breast pump.

[0006] In a first aspect, an embodiment of the present application provides a method for detecting the amount of milk in a breast pump, the method comprising: obtaining flow data from a flow sensor; the flow sensor detecting the flow data of milk in a milk flow path of the breast pump; obtaining milk storage amount data from the milk amount sensor; the milk amount sensor detecting the current milk storage amount data of a milk storage container; verifying the milk storage amount data according to the flow data to determine a verification result; and determining the milk amount of the breast pump according to the verification result.

[0007] In the above technical solution, the accuracy of milk volume detection of the breast pump can be improved by verifying the milk storage volume data through flow data.

[0008] In a possible implementation of the first aspect, the milk storage amount data is verified according to the flow data to determine the verification result, including: determining the flow rate within a first preset time range according to the flow data; determining the milk volume acceleration within a second preset time range according to the milk storage amount data; when the flow rate and the milk volume acceleration meet the first preset condition, determining the verification result as verification passed; when the flow rate and the milk volume acceleration do not meet the first preset condition, determining the verification result as verification failed.

[0009] In the above implementation, by judging whether the flow rate and the milk volume acceleration meet the first preset condition, it is judged whether the milk storage volume data is abnormal, thereby improving the accuracy of milk volume detection of the breast pump.

[0010] In a possible implementation manner of the first aspect, the first preset condition includes any one or more of the following: when the flow rate increases, the milk volume acceleration increases; when the flow rate decreases, the milk volume acceleration decreases; when the flow rate remains unchanged, the milk volume acceleration remains unchanged.

[0011] In a possible implementation of the first aspect, the milk storage amount data is verified according to the flow data to determine the verification result, including: determining the flow rate within a first preset time range according to the flow data; determining the increase in milk volume within a second preset time range according to the milk storage amount data; if the flow rate and the increase in milk volume meet the second preset condition, determining the verification result as a passed verification; if the flow rate and the increase in milk volume do not meet the second preset condition, determining the verification result as a failed verification.

[0012] In the above implementation, by judging whether the flow rate and the increase in milk volume meet the second preset condition, it is judged whether the milk storage volume data is abnormal, thereby improving the accuracy of milk volume detection of the breast pump.

[0013] In a possible implementation manner of the first aspect, the second preset condition includes any one or more of the following: when the flow rate is greater than a preset flow rate, the increase in milk volume is greater than the preset increase; when the flow rate is less than or equal to the preset flow rate, the increase in milk volume is less than or equal to the preset increase.

[0014] In a possible implementation of the first aspect, the milk storage amount data is verified according to the flow data to determine a verification result, including: determining an average flow within a first preset time range according to the flow data; determining a first milk volume increase according to the average flow and the time length of the first preset time range; determining a second milk volume increase within a second preset time range according to the milk storage amount data; if the first milk volume increase and the second milk volume increase meet a third preset condition, determining the verification result as a passed verification; if the first milk volume increase and the second milk volume increase do not meet the third preset condition, determining the verification result as a failed verification.

[0015] In the above implementation, by judging whether the first milk volume increase calculated according to the flow data and the second milk volume increase calculated according to the milk storage data meet the third preset condition, it is judged whether the milk storage data is abnormal, thereby improving the accuracy of milk volume detection of the breast pump.

[0016] In a possible implementation manner of the first aspect, the third preset condition includes any one of the following: the difference between the first milk amount increase and the second milk amount increase is within a preset difference range; the difference between the first milk amount increase and the second milk amount increase is within a preset difference range, and the first milk amount increase and the second milk amount increase are both less than a preset upper limit value.

[0017] In a possible implementation manner of the first aspect, determining the milk volume of the breast pump according to the verification result includes: when the verification result is verification failure, determining the milk volume of the breast pump based on at least one of milk storage volume data and flow data.

[0018] In the above implementation, in the case of verification failure, the milk storage amount of the breast pump is re-determined to obtain a more accurate milk storage amount.

[0019] In a possible implementation of the first aspect, when the verification result is a verification failure, determining the milk volume of the breast pump based on at least one of the milk storage amount data and the flow data, including: when the verification result is a verification failure, determining the average flow rate and the time length of the flow data based on the flow data; and calculating the milk volume of the breast pump based on the average flow rate and the time length.

[0020] In the above implementation, when the verification fails, it means that the detection of the milk volume sensor in the breast pump is inaccurate, and the milk storage volume is determined by the flow data, so as to obtain a more accurate milk storage volume.

[0021] In a possible implementation manner of the first aspect, the method also includes: when the verification result is a verification failure, executing a preset operation; wherein the preset operation includes any one or more of the following: controlling a display module in a breast pump to suspend updating the amount of milk calculated based on the milk storage data; suspending sending the amount of milk calculated based on the milk storage data to an electronic device that communicates with the breast pump; controlling a display module in the breast pump to display prompt information; sending indication information to an electronic device that communicates with the breast pump, the indication information being used to instruct a display module of the electronic device to display prompt information; controlling a display module in the breast pump to display the amount of milk calculated based on the flow data; sending the amount of milk calculated based on the flow data to an electronic device that communicates with the breast pump.

[0022] In the above implementation, remedial measures can be executed after verification fails to prevent the breast pump from working incorrectly or feeding back erroneous information to the user due to inaccurate milk storage amount data.

[0023] In a possible implementation manner of the first aspect, determining the milk volume of the breast pump according to the verification result includes: when the verification result is successful, determining the milk volume of the breast pump based on the milk storage amount data.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of a breast pump provided in an embodiment of the present application.

[0035] like Figure 1 As shown, the breast pump 1 comprises a breast shield 10 , a milk storage container 20 and a host 30 .

[0036] The breast shield 10 is used to cover the human breast and fit with the breast. The breast shield 10 includes a trumpet-shaped flange for fitting the breast and a nipple channel for accommodating the nipple. In some cases, the nipple channel can also be arranged in the milk storage container 20.

[0037] The milk storage container 20 is used to receive and store breast milk collected by the breast shield 10 , and the milk storage container 20 is in communication with the breast shield 10 .

[0038] Optionally, the milk storage container 20 includes a milk cap, a milk bowl, a milk bottle, etc., which is not limited in the present application.

[0039] The host 30 is also provided with a negative pressure mechanism, which can directly or indirectly apply negative pressure to the breast shield 10 to suck breast milk into the milk storage container 20 .

[0040] Negative pressure mechanisms include, but are not limited to, piezoelectric pumps, diaphragm pumps, hydraulic pumps, mechanical pumps, and the like.

[0041] Optionally, the host 30 may also include one or more components such as a power supply module, a negative pressure air circuit, a control circuit board, and a solenoid valve.

[0042] The energy supply module is used to provide energy to the negative pressure mechanism to support the operation of the negative pressure mechanism. Specifically, the energy supply module can be a storage battery, a dry cell, or can be directly connected to an external power source through a power cord.

[0043] Understandably, Figure 1 Only one optional structure of a breast pump is illustrated, but it does not mean that the present application must be applied to a breast pump with the above structure. The breast pump can also be in a form where the main unit is separated from the milk storage container. For example, the main unit is connected to the milk storage container through an air pipe, or the main unit is arranged on the upper part of the milk storage container, and the breast shield is arranged between the main unit and the milk storage container. The present application does not limit the structure of the milk storage container.

[0044] Please refer to Figure 2 , Figure 2 yes Figure 1 Cross-sectional view of a breast pump.

[0045] Figure 2 The milk flow path is indicated by a dotted line, and the flow direction in the milk flow path is indicated by an arrow. After the milk flows out of the breast, it flows into the milk storage container 120 along the flow direction.

[0046] The flow detection sensor includes: one of a capacitive sensor, an ultrasonic sensor, an acoustic sensor, and an optical sensor. Preferably, when the flow detection sensor is a capacitive sensor, the capacitive sensor is specifically a differential capacitive sensor assembly.

[0047] The differential capacitance sensor assembly is used to detect the mutual capacitance between two electrodes of a capacitor, and its output result is a capacitance change value between the two electrodes or a digital signal converted from the capacitance change value.

[0048] For the sake of convenience, the capacitor formed by two electrodes that are parallel to each other and arranged oppositely in the differential capacitance sensor assembly is called a parallel capacitance group. The parallel capacitance group includes two parallel electrodes that are arranged oppositely.

[0049] In addition, the differential capacitive sensor assembly includes, in addition to the parallel capacitor group, a control circuit connected to the parallel capacitor group. The control circuit is used to charge the parallel capacitor group and collect the charge on the parallel capacitor group after a preset time, and determine the capacitance value of the parallel capacitor group according to the charge change speed and / or charge change amount.

[0050] The control circuit includes a conversion unit, and the conversion unit includes an excitation module, a sampling module and a conversion module.

[0051] The excitation module generates a charging signal for charging the differential capacitance sensor component. The charge on the differential capacitance sensor component is transmitted to the conversion module through the sampling module, and the conversion module converts the analog voltage into a digital signal.

[0052] The conversion module is connected to the processing unit, and the processing unit is used to calculate the state parameter of the milk storage container corresponding to the differential capacitive sensor assembly according to the digital signal.

[0053] Optionally, the conversion unit is a capacitance-to-digital converter, and optionally, the conversion module is an analog-to-digital converter (ADC).

[0054] in, Figure 2The flow detection sensor 41 is included. Optionally, the milk flow path includes an outer wall that does not contact the milk and an inner wall that contacts the milk; the flow detection sensor is arranged on the outer wall of the milk flow path, or on the side of the outer wall of the milk flow path away from the inner wall of the milk flow path.

[0055] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of a method for detecting the amount of milk in a breast pump provided in an embodiment of the present application. Figure 3 As shown, the method 100 includes: steps 110 to 140.

[0056] Step 110: Acquire flow data from a flow sensor; the flow sensor detects flow data of milk in the milk flow path of the breast pump.

[0057] The flow data includes flow rate and the collection time corresponding to each flow rate.

[0058] The milk flow path is the flow section of the milk from the breast to the milk storage container. The milk flow path includes but is not limited to at least one of the flange in the breast shield, the nipple channel in the breast shield, the negative pressure chamber, the one-way valve, and the nipple channel in the milk storage container.

[0059] In a possible implementation, the flow data is the flow data of a certain area in the milk flow path. For example, if the length of the milk flow path is 10 cm, only the flow of the milk flow path within the range of 2 cm-4 cm is detected to obtain the flow data.

[0060] In another possible implementation, the flow data is flow data of the entire milk flow path.

[0061] Step 120: Acquire milk storage volume data from a milk volume sensor; the milk volume sensor detects the current milk storage volume data of the milk storage container.

[0062] The milk storage volume data includes the milk storage volume and the collection time corresponding to each milk storage volume.

[0063] Among them, the current breast pump is usually equipped with a milk volume sensor to detect the milk volume in the milk storage container, so as to obtain the milk volume data. The milk volume sensor includes but is not limited to: a differential capacitance sensor, a photoelectric sensor, an ultrasonic sensor, etc. This application does not limit the method of obtaining the milk volume data.

[0064] Step 130: Verify the milk storage volume data according to the flow data and determine the verification result.

[0065] Among them, the change of flow data will be ahead of the change of milk storage volume data, because milk needs to pass through the milk flow path to flow into the milk storage container. Therefore, when the change of flow data is detected, the milk may not have flowed into the milk storage container, and the milk storage volume data of the milk storage container has not changed. Therefore, the flow rate and average flow rate obtained by subsequent determination based on the flow data in this application are within the first preset time range, and the milk volume acceleration and milk volume increase obtained by subsequent determination based on the milk storage volume data in this application are within the second preset time range.

[0066] The first preset time range may be the same as the second preset time range. However, preferably, the first preset time range and the second preset time range have the same time length, but the time starting point of the second preset time range lags behind the time starting point of the first preset time range, and the difference between the two time starting points is determined by the time required for milk to flow from the detection position of the flow sensor in the milk flow path into the milk storage container.

[0067] Among them, the present application has multiple ways of verifying the milk storage data based on the flow data, which are described in detail below.

[0068] In a possible implementation, step 130 includes the steps of: determining the flow rate within a first preset time range based on the flow data; determining the milk volume acceleration within a second preset time range based on the milk storage volume data; when the flow rate and the milk volume acceleration meet the first preset condition, determining the verification result as verification passed; when the flow rate and the milk volume acceleration do not meet the first preset condition, determining the verification result as verification failed.

[0069] The milk volume acceleration is the rate of increase of the milk volume, for example, the volume of milk increased within 1 second or the height of the liquid level increased within 1 second.

[0070] The first preset condition includes any one or more of the following: (1) When the flow rate increases, that is, when the flow acceleration is greater than zero, the rate of increase of milk volume increases.

[0071] (2) When the flow rate decreases, that is, when the flow acceleration is less than zero, the rate of increase of milk volume decreases.

[0072] (3) When the flow rate remains unchanged, that is, the flow acceleration is equal to zero, the milk volume acceleration remains unchanged.

[0073] Furthermore, the milk volume acceleration may be increased by the milk volume acceleration being greater than zero, or the milk volume acceleration being greater than the first preset acceleration; the milk volume acceleration may be decreased by the milk volume acceleration being less than zero, or the milk volume acceleration being less than the second preset acceleration; the milk volume acceleration being constant may be the milk volume acceleration being equal to zero, or the milk volume acceleration being within the range from the second preset acceleration to the first preset acceleration; wherein the first preset acceleration is greater than zero and greater than the second preset acceleration. Because the flow sensor may be subject to external interference, the detected flow acceleration may always be in a state of slight fluctuation, so it is preferred to determine whether the first preset condition is met by using the first preset acceleration and the second preset acceleration.

[0074] The specific values ​​of the first preset acceleration and the second preset acceleration can be selected as needed, and this application does not impose any limitation.

[0075] In some cases, the verification is passed if all flow rates and all milk volumes meet the first preset condition. In other cases, the verification is passed if a preset percentage of flow rates and milk volumes meet the first preset condition. For example, if the time lengths of the first preset time range and the second preset time range are both 3S, and the preset percentage is 90%, then as long as the time for the flow rate and milk volume acceleration to meet the first preset condition exceeds 2.7S in 90% of the time, the verification is determined to be passed. The preset percentage can be selected as needed and will not be repeated here.

[0076] In another possible implementation, step 130 includes the steps of: determining the flow rate within a first preset time range based on the flow data; determining the increase in milk volume within a second preset time range based on the milk storage volume data; if the flow rate and the increase in milk volume meet the second preset condition, determining the verification result as a passed verification; if the flow rate and the increase in milk volume do not meet the second preset condition, determining the verification result as a failed verification.

[0077] The second preset condition includes any one or more of the following: (1) When the flow rate is greater than the preset flow rate, the increase in milk volume is greater than the preset increase.

[0078] (2) When the flow rate is less than or equal to the preset flow rate, the increase in milk volume is less than or equal to the preset increase.

[0079] Optionally, the preset flow rate and the preset increase are both zero. That is, when the flow rate is greater than zero, it means that milk flows into the milk storage container, so the increase in the amount of milk in the milk storage container is greater than zero.

[0080] However, because the flow sensor may be affected by external interference, the detected flow may always be in a state of slight fluctuation, so the preset flow is preferably zero plus the first preset allowable fluctuation value, and the preset increase is preferably zero plus the second preset allowable fluctuation value. The first preset allowable fluctuation value and the second preset allowable fluctuation value can be selected as needed, and this application does not impose any restrictions.

[0081] In another possible implementation, step 130 includes the steps of: determining an average flow rate within a first preset time range based on the flow data; determining a first milk volume increase amount based on the average flow rate and the time length of the first preset time range; determining a second milk volume increase amount within a second preset time range based on the milk storage data; determining a verification result as a passed verification if the first milk volume increase amount and the second milk volume increase amount meet a third preset condition; and determining a verification result as a failed verification if the first milk volume increase amount and the second milk volume increase amount do not meet the third preset condition.

[0082] The third preset condition includes any one of the following: (1) The difference between the first milk volume increase amount and the second milk volume increase amount is within a preset difference range.

[0083] (2) The difference between the first milk volume increase amount and the second milk volume increase amount is within a preset difference range, and both the first milk volume increase amount and the second milk volume increase amount are less than a preset upper limit value.

[0084] In some cases, the difference between the first milk volume increase and the second milk volume increase is within the preset difference range. It may also be that the flow sensor and the milk volume sensor are both disturbed by external factors, causing the detection values ​​to rise synchronously. For example, when the flow sensor and the milk volume sensor are both capacitive sensors, it may be that both are affected by human touch, causing the capacitance detection values ​​to rise simultaneously. Therefore, condition (2) in the third preset condition also introduces a preset upper limit value, so as to detect the situation where both are disturbed by external factors, thereby further improving the accuracy of milk volume detection.

[0085] Step 140: Determine the milk volume of the breast pump according to the verification result.

[0086] In case of verification failure: determining the milk volume of the breast pump based on at least one of the milk storage volume data and the flow volume data.

[0087] In a possible implementation, the milk storage amount data at the most recent successful verification is determined as the milk storage amount of the breast pump. For example, if the verification is successful at 9S and fails at 10S, the milk storage amount at 9S is used as the milk storage amount at 10S.

[0088] In another possible implementation, the average flow rate and the time length of the flow data are determined based on the flow data; and the milk volume of the breast pump is calculated based on the average flow rate and the time length. Thus, when the milk volume sensor is disturbed, the flow data is used to calculate the correct milk storage volume, thereby improving the milk volume detection accuracy of the breast pump.

[0089] When the verification is successful, the current milk volume in the milk storage volume data detected by the milk volume sensor is determined as the milk volume of the breast pump.

[0090] Optionally, the method for detecting the amount of milk in a breast pump provided in the present application further comprises the step of: executing a preset operation when the verification result is a verification failure.

[0091] The preset operations include any one or more of the following.

[0092] (1) Controlling the display module in the breast pump to stop updating the milk volume calculated based on the milk storage volume data; (2) Suspend sending the milk volume calculated based on the milk storage data to the electronic device communicating with the breast pump.

[0093] (3) Control the display module in the breast pump to display prompt information.

[0094] (4) Sending instruction information to an electronic device that communicates with the breast pump, where the instruction information is used to instruct a display module of the electronic device to display prompt information.

[0095] (5) Control the display module in the breast pump to display the amount of milk calculated based on the flow data.

[0096] (6) Sending the milk volume calculated based on the flow data to an electronic device that communicates with the breast pump.

[0097] Optionally, the display module in the breast pump is a display screen in the breast pump. The display screen in the breast pump is usually arranged in the host.

[0098] Optionally, the breast pump communicates with the electronic device via a data line, and / or communicates with the electronic device via a wireless communication module, such as a Bluetooth module or a WIFI module.

[0099] Optionally, the display module of the electronic device is a display screen of the electronic device.
