Description

Milk intake monitoring device, preparation method and monitoring method for parent-fed infants Technical Field The invention relates to the technical field of data monitoring, in particular to a device for monitoring milk intake of a parent breast-fed infant, a preparation method and a monitoring method. Background Accurate measurement of real milk intake during breast-feeding of infants has been a central problem in the field of breast-feeding. In the traditional feeding environment, it is difficult to judge how much milk the infant drinks at all, and further the feeding effectiveness cannot be scientifically estimated, so that many mothers and clinical nursing staff lack quantitative basis on feeding guidance. Common methods for estimating milk intake of breast milk in medical research include weighing methods (weight before and after test weighing), diaper number and weight gain evaluation, stable isotope techniques (such as deuterated water method), which have obvious disadvantages such as being affected by urination and defecation of infants, low accuracy or measurement with no real-time performance. In the prior art, the sensor is worn on the surface of the breast, and the milk intake of the infant is estimated by detecting the electrical change of breast tissues in the feeding process. The bioelectrical impedance electrode is adopted, and the structure of the bioelectrical impedance electrode comprises a sensing unit attached to the surface of the breast skin, a signal acquisition circuit, a wireless communication module and a data processing terminal. Continuous monitoring in the breast milk parent feeding process is realized to a certain extent, but because of the complex breast tissue structure, the sensing signal is easily influenced by various factors such as skin contact state, sensor position, breast deformation, blood flow change, individual difference and the like, and the signal stability and the measurement accuracy are still limited. Meanwhile, the existing sensor materials and structures still have defects in the aspects of flexibility, fit and long-term wearing comfort, and the comprehensive requirements of noninvasive property, comfort and reliability under the breast milk parent-feeding scene are difficult to meet. In summary, the prior art has the problems of non-real-time measurement, complex operation, insufficient monitoring precision or difficult application to breast milk parent feeding scenes and the like.
