| Abstract: | The importance of breastfeeding is recognised, as there is extensive evidence of the beneficial qualities for mother and child. But only around 41% of babies younger than 6 months is breastfed exclusively. The combination of perceived lactation insufficiency (lack of volume) and the nutritional issues (lack of calories) are the main reasons mother stop breastfeeding. There are no current techniques that research both real-time. That is why an idea has been proposed, to create a measuring device in the form of a nipple shield with photonic-based measuring methods in one of the channels. As getting more insight into the actual lactation and nutrional values will result in higher confidence for mothers and more understanding in breastfeeding problems. In this thesis, a setup is made to measure the flow of breastmilk through a channel using echo Particle Image Velocimetry (echo PIV). The experimental setup consists of three main parts and several connecting parts. The three main parts are the breast pump, the ultrasound transducer and the channels within a block of polyacrylamide (PAA). To connect the parts, thin tubes and 3D printed coupling pieces are used. Different concentrations are tried when making the PAA. The flow is calculated by measuring the mean velocity perpendicular to the channel and multiplying it by the cross sectional area of the channel. The flow of the circular shaped channel is 0,0057 ml/s and of the square shaped channel is 0,0068 ml/s. A working experimental setup was made in which successfully a liquid flow through a channel was measured using echo PIV. |
