Breast pump containers and methods
Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container assembly.
1. A container assembly for a pump, comprising:
a body;
a neck portion; and
a valve assembly;
wherein the valve assembly is configured to mate with the pump and the container assembly defines a sealed or sealable structure in combination with the pump and the valve assembly further includes an integrated valve, the integrated valve including a port formed on a first outside surface of the container assembly and a foam assist member configured on an opposite outside surface of the container assembly, the foam assist member maintaining the port closed until an opening pressure is reached.
2. The container assembly of claim 1 , wherein the valve assembly is integrated into the container assembly.
3. The container assembly of claim 1 , wherein the container assembly is sealed.
4. The container assembly of claim 1 , wherein the container assembly is airtight.
5. The container assembly of claim 1 , wherein the container assembly is formed from two sheets of material band welded together along a perimeter.
6. The container assembly of claim 1 , wherein the valve permits milk inflow into the container assembly but prevents backflow.
7. The container assembly of claim 1 , further comprising an hole formed in the neck portion and a grommet attached to the neck, wherein the grommet provides support to the container assembly when the container assembly is attached to an outlet of the pump.
8. The container assembly of claim 1 , wherein the valve opens to allow flow into the container assembly at about 25 mm Hg.
9. The container assembly of claim 1 , further comprising a support attached to the foam assist member, a hinge attached to the support that permits the support to rotate, and a latch for retaining the support in a position for engaging the foam assist member with the container assembly.
10. The container assembly of claim 1 , wherein the valve assembly includes a flapper.
11. The container assembly of claim 1 , wherein a portion of the neck includes a punched out portion, the punched out portion cooperating with a port to define an integrated valve.
12. The container assembly of claim 1 , further comprising a pull tab connected to the valve assembly, wherein pulling on a pull tab results in removing the valve from the container assembly.
13. The container assembly of claim 1 , further comprising a latch which can be rotated into engagement with the pump.
14. The container assembly of claim 1 , wherein the valve is a bicuspid valve formed by a pair of leaflets contained within an interior of the neck portion.
15. The container of claim 1 , further comprising a outlet formed by the body of the container assembly, the outlet created by separating sheets forming the body of the container assembly.
