Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a breast milk flow monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the mother flow rate monitoring apparatus 100 according to an exemplary embodiment of the present invention includes an impedance measuring unit 110, a moisture amount converting unit 120, and a mother flow rate calculating unit 130. If necessary, the shape information input unit 140 and / or the breastfeeding flow rate corrector 150 may be further included.

The breast milk flow monitoring apparatus 100 according to an embodiment of the present invention may apply a predetermined current to an electrode attached to a breast of a measurement target, such as a mother breastfeeding a baby, and then apply a predetermined current to the body, that is, impedance. (impedance) is measured and converted to water content to calculate breast milk. In addition, by measuring the difference in the amount of water before and after breastfeeding to calculate the amount of breastfeeding or by measuring the rate of change of moisture in real time during breastfeeding can calculate the amount of breastfeeding through calculation with breastfeeding time.

The impedance measuring unit 110 includes a plurality of electrodes attached to the breast of the subject to be measured, and applies a minute current, for example, about 250 mA, to the electrode to measure internal resistance, that is, impedance, defined in the breast portion. . Impedance measurement may be performed, for example, by using a bio-impedance assessment (BIA).

The plurality of electrodes attached to the breast has an arrangement structure for impedance measurement suitable according to the shape of the breast. This will be described later with reference to related drawings.

The current applied to the electrode for impedance measurement can vary its frequency. A plurality of currents having different frequencies may be applied to the electrodes, respectively, and the impedance may be measured to more accurately convert the moisture amount in the moisture amount converting unit 120 to be described later.

The moisture amount converting unit 120 converts the impedance value measured by the impedance measuring unit 110 into the amount of moisture in the breast. It is possible to convert the amount of water from the impedance value by inverting the body in consideration of the effect of fat, muscle, water, etc. on the impedance value.

In addition, when there are a plurality of impedance values measured by applying a plurality of currents having different frequencies from the impedance measuring unit 110, the impedance values more accurately apply the effects of body fat, muscle, water, etc. on the impedance values. Since it can be made, more accurate moisture content can be converted from each impedance value according to various frequencies.

The mother's milk flow rate calculation unit 130 calculates a holding mother's milk amount of the subject to be measured from the amount of water in the breast converted by the moisture amount converting unit 120.

Since the amount of breast milk to be measured may vary according to eating habits, physical condition, environment, and the like, it is possible to check whether the breast milk is well generated or whether there is sufficient breast milk through the calculated breast milk.

In addition, the breast milk calculator 130 may calculate one or more of the baby's breast milk intake (feeding breast milk amount), the breast milk produced by the subject, and the like, according to breast milk performed by the subject.

In the case of breastfeeding milk can be calculated by the following method. According to one embodiment, the breast milk calculation unit 130 compares the amount of breast milk immediately before breastfeeding with the amount of breast milk immediately after breastfeeding and measures the amount of breast milk the baby has consumed, that is, a difference between the amount of breast milk changed during breastfeeding. Judging from the amount of breastfeeding the baby can be calculated. According to another exemplary embodiment, the breast milk calculator 130 may calculate the breastfeeding milk amount in real time by calculating a rate of change of the breast milk amount to be held while the subject is breastfeeding the baby. In addition, it is possible to calculate the breastfeeding amount of milk fed to the baby at this time from the average retention rate of breast milk change during breastfeeding time and breastfeeding time.

In the case of the generated milk flow rate, the milk flow rate calculation unit 130 may calculate the average generated milk flow rate per unit time from the difference in the retained milk flow rate for a predetermined time (eg, several minutes to several hours) when the measurement target does not breastfeed the baby. Can be.

One or more of the breast milk amount calculated by the breast milk amount calculating unit 130, that is, the amount of breast milk, breast milk, and the amount of milk produced, is numerically expressed to be monitored by a user through a display unit (not shown) or displayed using a graph or the like. Can be.

The breast flow rate monitoring apparatus 100 may further include a shape information input unit 140 that receives shape information about a breast shape of a measurement target.

In the conventional body fat measurement, the body fat was measured by considering the body as a cylinder, whereas when calculating the milk flow according to the present invention, it is generally limited to the breast portion of the measurement subject having a non-cylindrical shape. Information about the shape of the breast may be required.

Accordingly, the moisture content converting unit 120 converts the measured impedance value into a moisture amount corresponding to the volume of the breast calculated using the shape information of the breast shape of the measurement target input through the shape information input unit 140. You can do it.

Shape information about the shape of the breast includes measurement information acquired through actual measurement, underwear worn by the measurement subject, that is, the size information of a bra, which is a foundation that wraps the chest around the breast, and sensing information measured using a volumetric sensor. There may be more than one.

In addition, the shape information about the shape of the breast is included in the impedance measuring unit 110 to render a mathematical model that can be reproduced in a virtual three-dimensional space from a structure in which a plurality of electrodes attached to the breast of the actual measurement target is arranged. It may be three-dimensional modeling information obtainable through the process of making through.

In addition, the breast milk flow monitoring apparatus 100 may further include a breastfeeding milk flow rate correcting unit 150 that calculates the amount of breast milk generated per unit time of the measurement subject to correct breastfeeding milk amount of the breast milk calculated by the breast milk flow rate calculation unit 130.

While the milk is breast-feeding to the baby, the milk continues to be produced, and the amount of milk produced varies greatly depending on the characteristics of the individual. Therefore, the breastfeeding milk flow rate correcting unit 150 calculates the generated breast milk amount of the measurement target one or more times in advance and stores it in a memory (not shown), and more accurately corrects the breastfeeding milk flow rate calculated by the breast milk flow rate calculating unit 130.

While the measurement target is breastfeeding the baby, the amount of water in the breast includes not only a quantitative change due to breastfeeding but also a quantitative change due to breast milk production, and thus, the breastfeeding amount calculated by the breastfeeding unit 130 is pre-calculated. By adding up the product of the amount of milk produced per unit time and breastfeeding time, the value can be corrected with a more accurate breastfeeding amount.

In addition, since the amount of generated milk per unit time may vary according to the diet, physical condition, environment, etc. of the subject to be measured, more accurate correction may be made by measuring the amount of produced milk per unit time immediately before breastfeeding.

Each electrode 30 is arranged so as not to overlap each other, by being attached as close as possible to the breast of the subject to be measured to enable accurate impedance measurement.

Referring to FIG. 4, an electrode 40 for impedance measurement is arranged on the surface of a virtual non-cylindrical shape 10c that is the same or similar to the hemisphere surrounding the breast.

The electrode 40 is a discrete electrode in the form of a dot, and the bottom surface 14c of the virtual non-cylindrical shape 10c and the plane 16c which do not meet in the virtual non-cylindrical shape 10c are not included. It is arranged in a meshing structure along the portion 18c that meets the virtual non-cylindrical surface 12c. The electrode 40 may be a patch electrode that can be attached as closely as possible to the breast of the subject.

It is. The electrode 50 may be a patch electrode that can be attached as closely as possible to the breast of the subject.

Using one electrode 50-1 as a reference electrode, one-to-one matching with another electrode is possible, and impedance measurement is possible, and the plurality of electrodes 50 may be measured while changing the reference electrode.

As the number of the electrodes 20, 30, 40, or 50 illustrated in FIGS. 2 to 5 increases, the accuracy of impedance measurement by the impedance measuring unit 110 may be improved.

As shown in FIGS. 2 to 5, the virtual non-cylindrical shape 10a may be three-dimensionally modeled from the structure in which the electrodes 20, 30, 40, or 50 are arranged, and the shape information input unit 140 described above may be used.

Figure 6 is a flow chart of a breast milk flow monitoring method according to an embodiment of the present invention.

Each step described below may be performed by each internal component of the milk flow monitoring device, but will be collectively described as a milk flow monitoring device for the convenience of understanding and description. In addition, it is assumed that the electrode included in the breast milk flow monitoring apparatus according to an embodiment of the present invention is attached in close contact with the breast of the subject.

A minute current is applied to the electrode to measure the internal resistance value, that is, the impedance (step S210). The measurement of the impedance can be made according to, for example, a bioimpedance measurement method.

The time point at which the current is applied may be at any time for measuring the retained breast milk, immediately before and just after breastfeeding for measuring the breast milk amount, or during breastfeeding. It may also be before or after a predetermined time interval before breastfeeding to measure the amount of breast milk produced.

In addition, in applying a current, the frequency may be changed in various ways, and an impedance corresponding to each frequency may be measured (step S212).

The impedance value measured in step S210 is converted into the amount of water in the breast of the measurement target (step S220). To this end, the body fat, muscle, water, etc. can be inverted in consideration of the effect on the impedance value. In addition, when impedance measurement for various frequencies is performed in step S212, more accurate moisture amount conversion may be performed using a plurality of impedance values according to each frequency.

Here, the shape information of the breast shape of the measurement target is input (step S222), and the conversion to the amount of water corresponding to the breast volume of the measurement target is more accurately performed using the shape information of the breast and the measured impedance (step S224). Can be. Here, the shape information may be one or more of measurement information, underwear size information, sensing information, 3D modeling information according to an electrode array structure, and the like.

From the converted amount of water in the breast, the amount of breast milk held by the measurement subject is calculated (step S230).

Thereafter, one or more of breastfeeding milk production, milk production milk production, etc. may be calculated from the holding milk flow rate of the measurement subject.

According to one embodiment, compared to the amount of holding breast milk immediately before breastfeeding and the amount of holding breast milk immediately after breastfeeding, which is a result of performing steps S210 to S230 immediately before and after breastfeeding, and comparing the difference in the amount of holding breastmilk changed during breastfeeding time. The milk flow rate can be calculated (step S240a).

According to another embodiment, the rate of change of the amount of breast milk held during breastfeeding may be calculated to calculate the amount of breastfeeding in real time (step S240b). The average rate of change in breastfeeding and breastfeeding time may be used to calculate the amount of breastfeeding given to a baby.

According to another embodiment, the amount of generated milk per unit time may be calculated from the difference in the amount of retained milk changed for a certain time before the breastfeeding time (step S240c).

One or more of the calculated reserve milk, lactation breast milk, and the amount of breast milk produced are expressed numerically or graphically on a display to allow the user to monitor breast milk.

While the subject is breastfeeding the baby, breast milk continues to be produced, and the amount of milk produced varies greatly depending on the characteristics of the individual. Therefore, the breastfeeding milk flow rate correcting unit 150 needs to calculate the breastfeeding amount generated per unit time of the measurement target one or more times in advance and store it in the memory, and correct the calculation of the breastfeeding milk flow rate.

In this case, steps S210 to S240c are performed at predetermined time intervals before breastfeeding to measure the amount of breast milk of the subject to be measured to calculate an average amount of breast milk per unit time. The total amount of breast milk generated during breastfeeding time is calculated using the amount of breast milk produced per unit time calculated in step S240c (for example, the amount of breast milk produced during breastfeeding time is multiplied by the amount of breastmilk produced per unit time). By adding up the breastfeeding milk flow rate calculated through S230a or S230b (step S250), it is possible to more accurately monitor the breastfeeding milk fed to the baby.

Naturally, the above-described breast milk flow monitoring method may be performed by an automated procedure according to a time series sequence by a software program embedded in the breast milk flow monitoring apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable media readable by a digital processing device, and the method is implemented by being read and executed by the digital processing device. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

Here, the mother milk flow monitoring apparatus is configured as a separate terminal to perform the above-described mother milk milk flow monitoring method to obtain information on the milk milk flow, and transmit the corresponding information to the web server through wired and wireless communication to accumulate and store. Here, the web server may display the amount of breast milk measured through a blog, a homepage, a website, and so on, that is, the amount of breast milk held, the amount of breast milk ingested by the target baby (breast milk), and the amount of milk produced. It can be displayed in conjunction with the baby's growth curve, or compared with the average mother's holding milk, the amount of milk produced, and the average baby's standard milk intake.

Or, the remaining components except the impedance measuring unit of the breast milk flow monitoring device are implemented as a program in the web server, and the operation of calculating the change of breast milk flow rate on the web server and calculating the breastfeeding milk flow rate for the impedance value transmitted to the web server. The results can be accumulated and stored in a database corresponding to the subject or baby. The measured amount of breast milk, that is, the amount of milk held, the amount of breast milk ingested by the target baby (feeding breast milk), and the amount of milk produced can be displayed through blogs, mini homepages, websites, etc. It can be displayed in conjunction with the curve or compared to the average mother's holding milk, production breast milk, and average baby's standard milk intake.
