In an embodiment the breast shield of the present invention features a one-way flow valve positioned covering the interior of the funnel so as to enable expressed milk back flow prevention thereby reducing loss of expressed milk and keeping the breast free of accumulated expressed milk. The one-way flow valve thus helps ensure a comfortable and complete expression without the breast becoming wet/saturated with expressed milk.
In an embodiment the breast shield of the present invention features an adjustable range of milk drain holes for milk exiting to accommodate differences in the length of the nipple. The milk drain holes could alternatively be placed in different locations, and/or increased in number to facilitate a plurality of different models with finer and finer degrees of precision as to suitability for specific nipple lengths. The milk drain holes may alternatively be reduced to a single hole without an accompanying stopper.
In all embodiments, the breast receiving cone can be made from a material that is food grade, sterilizable, washable, and reusable. The one-way flow valve is made from a material that is soft feeling to the sense of touch, food grade, sterilizable, washable, reusable and moves easily and readily to enable opening the one-way flow valve flaps when the one-way flow valve is placed into the inside of the funnel of the breast receiving cone thereby creating the breast receiving cone with one-way flow valve positioned to enable a back flow prevention. The one-way flow valve is positioned above a narrowed neck flange and below the milk drain holes.
In alternate embodiments, the one-way flow valve is an external device/apparatus that is positioned in, and or connectively attached to a tube and one or both of the milk drain holes to enable a back flow prevention of expressed milk once drawn past said once-way flow valve.

In an embodiment the breast shield of the present invention features a one way valve on end connectively attached to the exit end that connects to the breast pump.
The breast shield of the present invention can be configured to reduce and/or prevent spillage of woman's expressed milk during pumping phase in that the expressed milk exits breast nipple and follows a short (shallow) centrally guided path through the one way valve for said expressed milk to drain through milk line into container.
In an embodiment, the breast shield of the present invention is combined with a tube to connect either milk drain hole to a container to enable capture of expressed milk while using the breast receiving cone with a breast pump attached to the breast pump connection end. Expressed milk flows out of the breast shield of the present invention and through the connectively attached milk drain hole connection of the tube, through the tube and out the open end of the tube. When the tube is inserted through the cap the expressed milk can be collected directly into a container which the cap is connectively attached to.
In an embodiment, a nursing woman (mom) will utilize two breast shields to enable pumping from both breasts for milk to be expressed (pumped) at the same time. The present invention allows for one or two breasts to pump on the side lying, reclining and supine positions.
The present invention makes it easier and more comfortable to hold the breast shield in the correct (shield centered around the nipple) position since the woman's arm is resting on the arm of the chair or on the bed if she is not using a hands free pumping bra. It is noted that use of/with a hands free pumping bra to assist in holding the breast shield in the correct nipple centered in the opening position will prevent nipple tissue damage and reduce neck, shoulder and back fatigue and strain by avoiding the need to lean forward when pumping in upright position.
In one embodiment of the invention, there is a breast shield for a resting position use by a nursing woman to capture an expressed milk while using a breast pump comprising a breast receiving cone having a “breast cup” at a breast connection end, a narrowed neck flange, a funnel, and a breast pump connection end at an opposite end of said breast receiving cone comprising a first milk drain hole, a second milk drain hole, and a stopper having a shield attachment end and a milk drain hole plug configured to enable a closing of either said first milk drain hole or said second milk drain hole thereby enabling said nursing woman to use said breast pump to capture said expressed milk while said nursing woman is in said resting position.
