Breast shield with sensor
A presently preferred embodiment of the invention includes a breast shield for use on a human breast including a breast-receiving portion, which is sized and shaped to receive a nipple and at least some surrounding breast. One or more sensors are connected to the breast-receiving portion and capable of sensing changes in the breast. Alternate embodiments of this aspect of the present invention include a sensor being one or more, for example, of an optical sensor, an electrode, a thermal sensor and an acoustic sensor. The optical sensor may be adapted to detect changes in light reflected from the breast. The electrode may be a pair of electrode parts, a first of which is used to apply an output voltage to the breast and a second of which is used to receive current conducted from the first of the pair of electrode parts. The acoustic sensor may be adapted to detect changes in breast tissue.
1. A device for detecting one or more parameters associated with breast tissue, including skin, during breastmilk expression in a human female, comprising:
a breast shield having an interior part within which a portion of the breast is received including the nipple;
a plurality of sensors associated with said breast shield, said plurality of sensors adapted to detect a parameter associated with breast tissue, including skin, during breastmilk expression;
wherein said plurality of sensors are attached to said breast shield;
wherein said plurality of sensors have a portion which extends to said breast shield interior part and is in contact with the breast; and
wherein said plurality of sensors include an electrode extending from said contact through the breast shield and terminating in a connection for attachment to a wire.
2. The device of claim 1 wherein each said contact is electrically isolated.
3. The device of claim 2 wherein said plurality of sensors include a sensor which detects changes in an electrical field within the breast.
4. The device of claim 1 wherein said sensors include an optical sensor.
5. The device of claim 1 wherein said sensors include a sensor for detecting changes in a magnetic field within the breast.
6. The device of claim 1 wherein said sensors include a sensor for detecting pressure changes of the breast.
7. The device of claim 1 wherein said sensors include a sensor for detecting ultrasound.
