Technical Field

The invention belongs to the technical field of articles for daily use, relates to a breast feeding device, and particularly relates to a safety auxiliary device for breast feeding.

Background

Breastfeeding refers to the manner in which a mother's milk is used to feed an infant. Studies have shown that infants fed breast milk develop healthier results including enhanced immunity, improved intelligence, reduced incidence of sudden infant death, reduced childhood obesity, reduced incidence of allergic disease, and the like. Over the past few decades there has been increasing evidence of the health benefits of breast feeding, and recommendations for putting to practice have continued to increase. Currently, the world health organization believes that breastfeeding may reduce the mortality rate of children, and that the health benefits it brings may extend into adulthood. On a population basis, pure breast feeding during the first 6 months after birth is the recommended way of feeding infants, followed by continuous breast feeding with the addition of appropriate supplements, up to 2 years of age or longer.

The breast feeding has a standard process, for example, in order to avoid choking milk, the back of the infant needs to be taken after the breast feeding is finished. After the baby drinks the milk, the milk is filled in the lower part of the stomach, and the air is filled in the upper part of the stomach, so that the pressure in the stomach can be caused, and the milk spitting phenomenon can occur. Therefore, the feeder can timely help the baby to burp and discharge the gas, thereby reducing the stomach pressure and naturally lightening the milk spitting condition and frequency.

However, in the process of feeding, a feeder is easy to sleep, and an infant is also easy to sleep after the end of milk feeding; this may not only lead to forgetting to flap the back of the infant after the end of the feeding, but may even lead to asphyxiation of the infant.

In view of the above, there is an urgent need to design a safety device for breast feeding to overcome the disadvantages of the existing breast feeding methods.

The working principle of the invention is as follows: the feeder places the baby above the bottom support mechanism 1, and simultaneously fixes the baby through the first and second clasping mechanisms 3 and 4, respectively, as shown in fig. 1. At this time, the pressure sensor 12 can sense the pressure signal generated by the baby above the bottom supporting mechanism 1, and when the baby eats milk, a vibration signal is generated and sensed by the vibration sensor 13. The control circuit 11 acquires the pressure signal sent by the pressure sensor 12 and the vibration signal sent by the vibration sensor 13, and sends an alarm signal to the reminding mechanism when the pressure signal is higher than a set value and the vibration signal is lower than the set value.

In one embodiment, reading pressure value data transmitted to a mobile phone terminal by a Bluetooth module; because the data read by the sensor problem has a certain degree of missing and the value is 0, for the data of the type, because the quantity of the data is small, the missing value or the value of 0 is selected to be directly deleted; the data is then normalized for input to a machine learning algorithm.

The features are key parameters in the design of the classifier, and the feature engineering is undoubtedly the most difficult and time-consuming link in machine learning; after the learning of classification is determined, how to extract proper features becomes the core for optimizing the performance of the classifier; extracting features according to the past experience and the related expert knowledge of the field where the problem exists, or automatically learning the features by adopting a deep learning method; in the treatment of many problems, the method continuously tries to dig and screen new features through experiments and experiences; the system selects the characteristics of the characteristic sitting posture as follows: maximum pressure, mean pressure, minimum pressure, standard deviation of pressure, maximum value of pressure change.

In the statistical theory, for a given training sample set, the basic idea of classification learning is to draw a function in the sample space of the sample set to determine a partition hyperplane, and to partition the sample space according to different sample classes. A Support Vector Machine (SVM) is an algorithm for dividing a limited sample space by using an optimal classification plane and a kernel function based on a statistical theory. It is a machine learning method established by Vapanic et al based on VC (Vapnik-Chervonenkis) theory using SRM (structured Risk minimization) structure Risk minimization principle. The method has a good classification effect on small sample problems, can train high-dimensional samples, introduces kernel functions to perform nonlinear mapping, and processes nonlinear problems.

SVM is the best off-the-shelf two-class classifier. The result of low error rate can be obtained by applying the SVM classifier of basic form to the data, and good classification decision can be made for the data points outside the training set.

The pressure value is transmitted to the mobile phone terminal through the Bluetooth module, and the mobile phone puts the data received every 10 seconds into the trained model to predict and judge the milk sucking state of the baby.
