Description

Technical Field

[0001] The present invention relates to the technical field of breast pumps, and particularly relates to a method and a monitoring system for monitoring the capacity of a breast pump. Background Art

[0002] With the development of society, people's material life has become increasingly rich, and the pace of life has also become faster and faster. Childbirth is an indispensable activity for human reproduction. However, in the context of a fast-paced society, many working women find it difficult to breastfeed according to the needs of their babies. Moreover, with the improvement of living conditions, the amount of breast milk produced by lactating women is often excessive. Therefore, most of the time, breast milk is discharged and stored through a breast pump so that breastfeeding can be carried out on the baby at any time.

[0003] In the prior art, breast pumps usually adopt infrared and capacitive milk volume detection methods, but these two methods have certain disadvantages. For example, they are easily affected by the assembly gaps generated by different assemblies and the accumulation of tolerances during the assembly process, or the breast pump is used obliquely, which will lead to inaccurate detection and false measurement. The present application proposes a method and a monitoring system for monitoring the capacity of a breast pump to solve such problems. Summary of the Invention

[0004] Based on this, in order to solve the problems existing in the prior art, on the one hand, the present application provides a method for monitoring the capacity of a breast pump, including:

[0005] Taking the vertical state of the milk collection container as a reference, the MCU main control module establishes a corresponding spatial capacity calculation model;

[0006] The angle sensor monitors the tilt angle of the milk collection container and feeds back the tilt angle to the MCU control module;

[0007] The pressure sensor monitors the pressure value of breast milk on the bottom of the milk collection container at the current tilt angle, feeds back the pressure value to the MCU control module, and performs compensation calculation according to the tilt angle;

[0008] The MCU control module calls the spatial capacity calculation model corresponding to the tilt angle according to the tilt angle fed back by the angle sensor;

[0009] The MCU control module calculates the actual milk volume in the milk collection container according to the called spatial capacity calculation model and the pressure value fed back by the pressure sensor at the tilt angle.

[0010] Further, the calculation steps of the MCU control module include:

[0011] When the milk collection container is in a vertical state, the tilt angle is 0. At this time, the MCU control module substitutes the pressure value and the force-bearing area of the pressure sensor into the formula:

[0012] In F = P*S, the pressure P is calculated;

[0013] The calculated pressure is substituted into the formula:

[0014] In P = ρgh, the liquid level height h is calculated;

[0015] The MCU control module compares the calculated liquid level height h with the breast milk volume corresponding to the liquid level height in the space capacity calculation model to obtain the milk volume.

[0016] Furthermore, the calculation steps of the MCU control module further include:

[0017] When the milk collection container is in an inclined state, the MCU control module substitutes the inclination angle θ and the liquid level height h into the formula:

[0018] In h1 = h / cosθ, the actual liquid level height h1 in the inclined state is calculated;

[0019] The MCU control module compares the calculated liquid level height h1 with the breast milk volume corresponding to the liquid level height in the space capacity calculation model to obtain the actual milk volume.

[0020] Furthermore, it further includes:

[0021] The MCU control module transmits the calculated milk volume data to the display, and the display shows the milk volume value.

[0022] On the other hand, the present application provides a milk pump capacity monitoring system, which adopts the milk pump capacity monitoring method of any one of the above, including a host for controlling the milk pumping of the milk pump and data processing;

[0023] A milk collection container for collecting breast milk;

[0024] A pressure sensor is arranged at the bottom of the inner wall of the milk collection container, and the pressure sensor is electrically connected to the host. The pressure sensor is used to monitor the pressure change of the breast milk inside the milk collection container;

[0025] An angle sensor is arranged on the host or the milk collection container, and the angle sensor is electrically connected to the host. The angle sensor is used to monitor whether the milk collection container is inclined and the inclination angle.

[0026] Furthermore, an MCU control module is arranged inside the host, and the MCU control module is electrically connected to the pressure sensor and the angle sensor respectively. The MCU control module is used to control the milk pumping of the milk pump, process the data monitored by the pressure sensor and the angle sensor, and calculate the milk volume.

[0027] Furthermore, a space capacity calculation model of the milk collection container at different inclination angles is arranged inside the MCU control module.

[0028] Further, it further includes a display, and the display is electrically connected to the MCU control module.

[0029] Beneficial effects: Through the pressure sensor, the present application can timely feedback the pressure of the breast milk inside the milk collection container to the MCU control module, and can calculate the actual vertical height of the breast milk in the milk collection container. If the milk collection container is in an inclined state, through the inclination angle detected by the angle sensor, the actual vertical height of the breast milk in the milk collection container can be compensated and calculated. Then, the actual breast milk height is compared with the space capacity calculation model to obtain the volume of breast milk (i.e., the milk volume) in the milk collection container. Even if there are deviations in usage habits and differences in assembly techniques, resulting in assembly gaps, the milk volume can still be accurately measured. Description of the Drawings

[0039] As Figure 1-2 shown, the embodiment of the present application provides a method for monitoring the capacity of a breast pump. The monitoring method is applied to the breast pump capacity monitoring system in any one of the above embodiments, and includes:

[0040] S1. Based on the vertical state of the milk collection container, the MCU main control module establishes a corresponding spatial capacity calculation model;

[0041] S2. The angle sensor monitors the tilt angle of the milk collection container and feeds back the tilt angle to the MCU control module;

[0042] S3. The pressure sensor monitors the pressure value of breast milk on the bottom of the milk collection container at the current tilt angle, feeds back the pressure value to the MCU control module, and performs compensation calculation according to the tilt angle;

[0043] S4. The MCU control module calls the spatial capacity calculation model corresponding to the tilt angle according to the tilt angle fed back by the angle sensor;

[0044] S5. The MCU control module calculates the actual milk volume in the milk collection container according to the called spatial capacity calculation model and the pressure value fed back by the pressure sensor at the tilt angle.

[0045] In this embodiment, the milk collection container can be of any shape. The model can be established according to the initial designed shape of the milk collection container, and data on the internal capacity of the milk collection container can be established. Based on the vertical state of the milk collection container, the corresponding liquid volume at different liquid heights of the milk collection container is calculated to establish a database;

[0046] Through the pressure sensor, the pressure of the breast milk inside the milk collection container can be fed back to the MCU control module in real time, and the actual vertical height of the breast milk in the milk collection container can be calculated. If the milk collection container is in an inclined state, the inclined angle detected by the angle sensor can be used to compensate and calculate the actual vertical height of the breast milk in the milk collection container. Then, the actual breast milk height is compared with the space capacity calculation model to obtain the volume of breast milk (i.e., the milk volume) in the milk collection container. Even if there are deviations in usage habits and differences in assembly techniques, resulting in gaps in assembly, the milk volume can still be accurately measured.

[0047] As Figure 3 shown, in one embodiment, the calculation steps of the MCU control module include:

[0048] When the milk collection container is in a vertical state, the inclination angle is 0. At this time, the MCU control module substitutes the pressure value and the force-receiving area of the pressure sensor into the formula:

[0049] F = P * S to calculate the pressure P;

[0050] where F is the force received by the pressure sensor, P is the pressure, and S is the area of the pressure sensor receiving the pressure.

[0051] Substitute the calculated pressure into the formula:

[0052] P = ρgh to calculate the liquid level height h;

[0053] where ρ is the density of breast milk, g is the acceleration due to gravity, and h is the liquid level height.

[0054] The MCU control module compares the calculated liquid level height h with the breast milk volume corresponding to the liquid level height in the space capacity calculation model to obtain the milk volume.

[0055] When the milk collection container is in an inclined state, the MCU control module substitutes the inclination angle θ and the liquid level height h into the formula:

[0056] h1 = h / cosθ to calculate the actual liquid level height h1 in the inclined state;

[0057] where h1 is the breast milk liquid level height at different inclination angles.

[0058] The MCU control module compares the calculated liquid level height h1 with the breast milk volume corresponding to the liquid level height in the space capacity calculation model to obtain the actual milk volume.

[0059] In this embodiment, the force-bearing area of the pressure sensor is the area of the pressure sensor, and the force-bearing area of the pressure sensor can be very small. A single pressure sensor can be set at the center of the bottom. As long as the liquid still submerges the center of the bottom of the breast milk collection container, there will be no change in the force-bearing area. If it is tilted at a large angle during abnormal use (such as tilting close to horizontal), it can also be corrected by the angle sensor. When the tilting angle reaches the set value, the breast pump will issue an alarm and prompt the user to wear it correctly.

[0060] Furthermore, multiple pressure sensors can be set in a circle at the bottom of the breast milk collection container. In this way, no matter how large the tilting angle of the breast pump is, there will always be a pressure sensor submerged by the liquid.

[0061] In one embodiment, the breast pump capacity monitoring method further includes: the MCU control module transmits the calculated milk volume data to the display, and the display shows the milk volume value.

[0062] In this embodiment, through the display, the user can intuitively and clearly know the amount of breast milk sucked. And when the milk volume is greater than or equal to 180 mL, it will automatically stop working.

[0063] The embodiment of the present application also provides a breast pump capacity monitoring system, including: a main unit 1, and the main unit 1 is used to control the breast pump to suck milk and process data;

[0064] A breast milk collection container 2, and the breast milk collection container 2 is used to collect breast milk;

[0065] A pressure sensor 4, and the pressure sensor 4 is arranged at the bottom of the inner wall of the breast milk collection container 2. The pressure sensor 4 is electrically connected to the main unit 1, and the pressure sensor 4 is used to monitor the pressure change of the breast milk inside the breast milk collection container 2;

[0066] An angle sensor 3, and the angle sensor 3 is arranged on the main unit 1 or the breast milk collection container 2. The angle sensor 3 is electrically connected to the main unit 1, and the angle sensor 3 is used to monitor whether the breast milk collection container 2 is tilted and the tilting angle.

[0067] In this embodiment, any container that can collect and store breast milk can be regarded as the breast milk collection container 2. For example: a milk bottle, a bowl-shaped container, etc., and the breast milk collection container 2 can be of any shape;

[0068] The pressure sensor 4 is of a thin plate type or a thin film type, placed at the center of the bottom of the inner wall of the breast milk collection container 2. The angle sensor 3 is built into the breast milk collection container 2 or the main unit 1, and one or more pressure sensors 4 and angle sensors 3 can be set;

[0069] Among them, an MCU control module is provided inside the main unit 1. The MCU control module is electrically connected to a pressure sensor 4 and an angle sensor 3 respectively. The MCU control module is used to control the milk pumping of the breast pump, process the data monitored by the pressure sensor 4 and the angle sensor 3, and calculate the milk volume.

[0070] In this application, by setting the pressure sensor 4 and the angle sensor 3, the pressure sensor 4 is used to detect the pressure changes under different milk volumes, generate different electrical signals, and feedback them to the MCU control module inside the breast pump device for milk volume calculation. Combining with the current tilt angle of the milk collection container 2 monitored by the angle sensor 3 for compensation calculation, even if there are deviations in usage habits and differences in assembly techniques, resulting in gaps in assembly, the milk volume can be accurately measured.

[0071] In one embodiment, a space capacity calculation model for different tilt angles of the milk collection container 2 is set inside the MCU control module.

[0072] In this embodiment, for the establishment of the space capacity calculation model, the model can be established according to the initial designed shape of the milk collection container 2, and data on the internal capacity of the milk collection container 2 is established. Based on the vertical state of the milk collection container 2 as a reference, when calculating different liquid heights of the milk collection container 2, the corresponding liquid volumes are calculated to establish a database.

[0073] Specifically, when the space capacity calculation model is based on the 3D structural design of the milk collection container 2, by designing and calculating the three-dimensional space volume capacity of the milk collection container 2, and simulating the milk collection container 2 in different states and at different angles, when it can be stably placed vertically on a horizontal table, the actual capacity corresponding to the actual height of the breast milk liquid surface is calculated. The parameters of the milk collection container 2 in different states are input into the MCU main control module. For example: when one-fourth of the space inside the milk collection container stores breast milk, simulate and calculate how many ml of breast milk is stored in this one-fourth of the space, and what is the height of the breast milk liquid surface corresponding to the stable vertical placement on the horizontal table. If the milk collection container 2 is irregular, calculate different tilt states and then form data to input into the MCU main control module.

[0074] When the breast pump pumps milk, the MCU control module calculates the actual height of the breast milk inside the milk collection container 2, and then compares it with the space capacity calculation model to obtain the actual milk volume data.

[0075] In one embodiment, the milk pump capacity monitoring system further includes a display 5, and the display 5 is electrically connected to the MCU control module.

[0076] In this embodiment, the display 5 can display the milk volume data calculated by the MCU control module in real time. Among them, the current milk volume data can also be received through the APP.

[0077] The above are only the preferred embodiments of the present invention, and do not thereby limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
