1. A manually operated breast pump, comprising:
- a flexible insert for engaging a breast of a user, said flexible insert having a funnel-type shape;
a housing sealingly engaging said flexible insert;
a holder sealingly engaging said housing and said flexible insert, said holder providing an air volume in fluid isolation from breast milk passing through said flexible insert; and
a pump mechanism sealingly engaging said holder, said pump mechanism having a handle and a chamber, said chamber being in fluid communication with the air volume of said holder,wherein said handle can move so that an alternating negative pressure and positive pressure are created on said flexible insert and thereby on the user'"'"'s breast.

13. A manually operated breast pump, comprising:
-
a flexible insert for engaging a breast of a user, said flexible insert having a funnel-type shape; a housing sealingly engaging said flexible insert; a holder sealingly engaging said housing and said flexible insert, said holder providing an air volume in fluid isolation from breast milk passing through said flexible insert; and a pump mechanism sealingly engaging said holder, said pump mechanism having a handle extending in an upward direction from said holder and a vacuum chamber, said vacuum chamber being in fluid communication with the air volume of said holder, said handle having a grip above a pivot point and a lower end below a pivot point, wherein said handle moves by exerting a pressure on said grip to move said grip toward said housing and the breast of the user to create a negative pressure communicated to said flexible insert and thereby on the user'"'"'s breast and said handle moves said grip away from said housing to create a positive pressure communicated to said flexible insert and thereby on the user'"'"'s breast. - View Dependent Claims (14, 15, 16, 17)

18. A breast pump assembly for pumping of a breast, the assembly comprising:
-
a funnel having a size and shape that allows for receiving of the breast; a flexible insert sealingly engageable with said funnel to define an air volume in fluid isolation from the breast, wherein said air volume is evacuated thereby causing a vacuum to be applied to the breast; a holder having a handle for different holding angles, said holder being connected to said funnel, said handle having a gripping surface on at least a portion thereof, said gripping surface being made from a material that facilitates gripping thereof, said gripping surface being a first gripping surface on at least a portion of said handle, said holder having a base in proximity to said container; a container releasably connected to said holder and being in fluid communication with said holder and said funnel; and a pressure source in fluid communication with said funnel for supplying a vacuum to said funnel for pumping of the breast, said pressure source being separate from said handle. - View Dependent Claims (19, 20, 21, 22)
