Abstract
Description
Technical Field
[0001] This invention relates to the field of breastfeeding assistance devices, specifically to a breastfeeding assistance device, method, and storage medium. Background Technology
[0002] During breastfeeding, especially for new mothers, challenges often arise such as difficulty in determining the balance between milk supply and demand, and low feeding efficiency. Therefore, breastfeeding aids have emerged to address these issues. These aids can help monitor milk parameters, providing mothers with data to adjust feeding methods and understand lactation status, which is crucial for ensuring successful breastfeeding.
[0003] In the prior art, there is a breast milk detection device that uses a calorimeter sensor. Its principle is to detect the change in heat absorbed by the breast milk when it flows through the calorimeter sensor, convert the heat change data into an electrical signal, and then calculate the breast milk parameters based on a preset algorithm, thereby realizing real-time monitoring of the breast milk condition.
[0004] However, when using calorimetric sensors to calculate milk parameters, it's impossible to determine whether the milk channels are full; in other words, the calorimetric sensor cannot determine the milk level height within the milk channels. Since calorimetric sensor data is more correlated with milk flow rate, in two scenarios—high milk flow rate but insufficient milk channel filling, and slow milk flow rate but full milk channel filling—the amount of heat absorbed by the milk may be the same, leading to identical calculated milk parameters. However, in reality, the milk parameters (e.g., total milk volume) differ between these two scenarios, thus compromising the accuracy of the milk parameter calculations. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this application provides a breastfeeding assistance device, method, and storage medium. A control module determines milk parameters based on capacitance data from a capacitance sensor module. Since the capacitance data of the capacitance sensor module is related to the dielectric constant of the milk, the higher the degree of milk filling in the milk channel, the greater the dielectric constant. Therefore, the degree of milk filling in the milk channel affects the capacitance data used to calculate the milk parameters. Thus, changes in the degree of filling do not affect the accuracy of the final detected milk parameters, eliminating the need to separately determine the degree of milk filling in the milk channel and reducing calculation errors for the milk parameters.
[0006] To address the above problems, the present invention provides the following technical solution: In a first aspect, embodiments of this application provide a breastfeeding assistance device, including a milk detection device, a control module, and a capacitive sensor module, wherein the control module is communicatively connected to the capacitive sensor module; The milk detection device includes a cover and a milk channel section.

[0043] This application provides a breastfeeding aid device, method, and storage medium. The application uses a control module to determine milk parameters based on the capacitance data of a capacitance sensor module. Since the capacitance data of the capacitance sensor module is related to the dielectric constant of the milk, the higher the degree of fullness of the milk in the milk channel, the greater the dielectric constant. Therefore, the degree of fullness of the milk in the milk channel will affect the capacitance data used to calculate the milk parameters.

[0058] This application provides a breastfeeding aid device, method, and storage medium. The control module determines milk parameters based on the capacitance data of a capacitance sensor module. Since the capacitance data of the capacitance sensor module is related to the dielectric constant of the milk, the higher the degree of milk filling in the milk channel, the greater the dielectric constant.

[0124] Optionally, when the capacitance data includes voltage and current signals, the capacitance value of the capacitance sensor module is also determined based on the voltage and current signals.
[0125] Step S220: When it is determined that milk flows through the milk channel, the milk parameters are determined based on the capacitance data.
[0126] In this way, milk parameters are determined only when it is determined that milk is flowing through the milk channel, which can improve the accuracy of milk parameters and reduce the amount of calculation.
