Estimating the term…
A breast pump device (1) is equipped with or used in conjunction with an acoustic milk expression assessment system (6) for the purpose of obtaining an indication about a fat content of expressed milk. The acoustic milk expression assessment system (6) includes an acoustic sensor (61) and a processor (62) configured to process an acoustic signal received from the acoustic sensor (61) during operation of the breast pump device (1) when a milk receptacle (4) is used with the device (1). By recording sound during a pumping session, it is possible to determine a frequency shift in the sound of droplets falling down in the receptacle (4) and hitting a surface of the milk contained by the receptacle (4) with respect to a reference situation of a liquid having 0% fat content, which can be taken as a factor in estimating a value related to the fat content of the milk.
A method of obtaining an indication about a fat content of milk, wherein at least one liquid droplet is made to fall down on a quantity of the milk, wherein the sound of an event of the liquid droplet hitting a surface of the quantity of the milk is detected so as to obtain an acoustic signal of the event,
A computer program comprising computer program code means which is adapted, when said program is run on a computer, to implement the steps of:
An apparatus for obtaining an indication about a fat content of milk,
