Discrete apparatus for the expression and collection of breast milk
Disclosed herein is a breast pump. The breast pump includes a milk capture system that includes a cupped flange. The cupped flange includes a nipple recess for receiving a nipple. The breast pump further includes a manifold which may be removably connected to the cupped flange. The manifold includes a nipple cavity in which vacuum suction is applied to a nipple. The manifold further includes a spout that drains milk away from the vacuum suction. The breast pump further includes a milk collection system which is removably connected to the manifold. The milk collection system includes a milk receptacle for containing milk expressed from a breast. Further disclosed is a breast pump system which includes a milk capture system, a manifold, and a milk collection system.
1. A breast pump, comprising:
a milk capture system, including a flange having a nipple recess disposed therein;
a manifold including a top manifold portion and a bottom manifold portion, directly and removably connected to the flange, the top manifold portion including a nipple cavity in which vacuum suction is applied to a nipple, the top manifold portion further including: a spout draining milk in a direction that is away from the vacuum suction, and a sensor positioned in the bottom manifold portion;
a milk collection system, removably connected to the manifold, including a milk receptacle for containing milk drained into the milk receptacle through the spout in the manifold, wherein the milk receptacle is positioned directly below a portion of the flange while the breast pump is in an upright position and the bottom manifold portion is positioned at an angle from a vertical plane extending vertically from the center of the milk receptacle; and
a one-way valve interfacing with and connecting to a collar on the milk receptacle which defines an opening of the milk receptacle, the one-way valve enveloping the collar on the milk receptacle forming a spill-proof top for the milk receptacle when connected to the milk receptacle, the milk receptacle being insertable and connectable to the manifold during pumping to implement the one-way valve during pumping and as the spill-proof top which remains connected to the collar on the milk receptacle which defines the opening of the milk receptacle during removal from the manifold,
wherein the one-way valve also interfaces with the manifold on an inside portion of the manifold to maintain a vacuum between the one-way valve and the manifold.
2. The breast pump of claim 1 , wherein a remote pump is connected by pneumatic tubing to the manifold.
3. The breast pump of claim 1 , wherein the one-way valve is disposed between the spout and the milk receptacle when inserted and connected to the manifold.
4. The breast pump of claim 3 , wherein the one-way valve seals the milk receptacle when the milk receptacle is removed from the manifold.
5. The breast pump of claim 4 , wherein the sensor positioned in the manifold tracks milk collection in real time.
6. The breast pump of claim 3 , wherein the one-way valve comprises one or more duckbill valves.
7. The breast pump of claim 1 , wherein the one-way valve includes a vent for the milk receptacle.
8. The breast pump of claim 1 , wherein the bottom manifold portion provides a tortuous suction path from a pump motor to the nipple cavity.
9. The breast pump of claim 1 , wherein the spout is disposed within the manifold and wherein the spout is connected to the nipple cavity.
10. The breast pump of claim 9 , wherein the spout disposed within the manifold is connected to the nipple cavity by a hole in a surface that separates the nipple cavity from the one-way valve.
