Systems, devices and methods for assessing milk volume expressed from a breast
Systems and methods for assessing milk volume changes within a breast are described. Also described are systems and methods for assessing volume changes in the stomach of an infant.
1 . A measurement system for assessing milk volume expressed from a breast, comprising: a measurement device associated with the breast and arranged to facilitate measuring changes in breast volume or milk production or consumption, the measurement device including a first sensor spaced from a second sensor, the first sensor and the second sensor measuring impedance therebetween; wherein a change in the impedance between the first sensor and the second sensor on breast tissue is associated with a change in breast size and the change in breast size is sensed, quantified, and correlated by the measurement system to milk production and expression to assess a milk volume expressed from the breast.
2 . The system of claim 1 , wherein the measurement device includes:
a distal mount portion;
a proximal mount portion; and
a flexible intermediate portion that bridges the proximal and distal portions.
3 . The system of claim 2 , the measurement device further including a third sensor configured to sense compression and expansion of the flexible intermediate portion, and to provide information concerning the change in breast size.
4 . The system of claim 1 , the measurement device further comprising an antenna electrically connected to a circuit, the antenna configured to communicate wirelessly with an external device or to upload data to a network or cloud based server.
5 . The system of claim 1 , wherein the system is configured to be calibrated by recording signals from the first sensor and the second sensor at different stages of breast feeding and changes in the volume of milk in the breast.
6 . The system of claim 1 , wherein the system measures a displacement of a portion of the measurement device by a stress/strain measurement.
7 . The system of claim 1 , wherein the measurement device is designed to expand and extend along two main axes.
8 . The system of claim 1 , wherein one or more sensors are provided to detect one or more of heart rate, temperature, respiration or motion to facilitate other health management of a user.
9 . The system of claim 1 , wherein the system is integrated with a breast pump and is in communication with a phone or cloud to transmit and coordinate the milk production.
10 . The system of claim 1 , wherein the system is powered by one or more of body heat or motion.
11 . The system of claim 1 , wherein the impedance of the breast is assessed to quantify and correlate the impedance to the milk production or expression.
12 . The system of claim 1 , further comprising a camera or other image collecting device and an application developed for a smartphone or other electronic device, the camera configured to sense a pattern and correlate a change in the pattern, and render a volume change/amount that correlates to the change in the pattern.
13 . The system of claim 1 , further comprising a controller wirelessly communicating with the measurement device, the controller configured to calculate one or more of changes in the breast volume and the milk expressed from the breast.
