Manual breast pump with resilient return

1. A manual breast pump comprising:

a primary housing defining an inlet orifice, a central orifice, an a pump orifice all in fluid communication with one another, the primary housing including a pump chamber and a funnel;

a repositionable actuator disposed within the pump chamber and repositionable within the pump chamber between a retracted position and an extended position;

a handle including a handle protrusion, wherein the handle is pivotably mounted to the primary housing and capable of moving the repositionable actuator from the retracted position to the extended position;

a resilient strap comprising a first end and a second end, wherein the strap is mounted to the handle at the first end and to the primary housing at the second end; and

wherein the resilient strap further includes an opening through the first end that is configured to receive at least a portion of the handle protrusion to mount the resilient strap to the handle.

2. The manual breast pump of claim 1 , wherein the resilient strap is positioned external to the primary housing.

3. The manual breast pump of claim 1 , wherein the funnel comprises a hollow conical section having an interior that at least partially defines the central orifice and the pump orifice.

4. The manual breast pump of claim 3 , wherein the pump orifice overlies the central orifice.

5. The manual breast pump of claim 1 , further comprising an elastomeric valve mounted to the primary housing and located downstream from the central orifice.

6. The manual breast pump of claim 5 , wherein the elastomeric valve comprises a cylindrical wall that circumscribes a cylindrical wall of the primary housing to form a compression fit to mount the elastomeric valve to the primary housing.

7. The manual breast pump of claim 5 , wherein:

the elastomeric valve comprises a bounded conduit defined by a cylindrical valve wall, a first planar wall, and a second planar wall; wherein the first planar wall and the second planar wall converge proximate an end of the elastomeric valve to form a slit that is configured to selectively open and close the end of the valve.

8. The manual breast pump of claim 1 , further comprising a reservoir bottle mounted to the primary housing.

9. The manual breast pump of claim 8 , further comprising an elastomeric valve mounted to the primary housing and located downstream from the central orifice.

10. The manual breast pump of claim 1 , wherein:

the repositionable actuator includes a piston comprising

an elongated opening configured to receive a projection disposed on the handle.

11. The manual breast pump of claim 1 , wherein:

the repositionable actuator includes a piston,

the handle includes an elongated opening; and,

the piston includes a projection that is capable of being received by the elongated opening.

12. The manual breast pump of claim 1 , wherein:

the repositionable actuator includes a piston,

the pump chamber is partially defined by a circumferential wall that provides a linear travel path for the piston.

13. The manual breast pump of claim 1 , wherein:

the handle has an S-shaped profile and the protrusion has an hourglass-shaped profile.

14. The manual breast pump of claim 1 , wherein:

the primary housing includes a housing protrusion; and,

the resilient strap includes a second opening through the second end that is configured to receive at least a portion of the housing protrusion to mount the resilient strap to the primary housing.

15. The manual breast pump of claim 1 , wherein:

the repositionable actuator includes a piston: and,

the piston includes a circumferential recess that is configured to receive an elastomeric piston ring.

16. The manual breast pump of claim 1 , wherein the repositionable actuator includes a diaphragm.
