Abstract
A breast pump system for obtaining breast milk is provided. The system sealingly separates the air flow from the breast milk and uses a single air tube for both positive pressure and negative pressure to be applied to a woman's breast. The breast pump can have a piston/cylinder device for generating pressure that allows a user to control suction and cycle time.
Claims92
A breast pump system for expressing breast milk from a breast, the system comprising:
- a pressure source for generating a positive pressure and a negative pressure;
- and
- a breast cup in fluid communication with said pressure source, wherein said breast cup applies said positive pressure and said negative pressure to said breast.
A breast pump system for expressing breast milk from a breast, the system comprising:
- a cylinder having a cylinder volume;
- a piston movably disposed in said cylinder;
- a motor operably connected to said piston to generate a pressure in said cylinder volume;
- and
- a breast cup in fluid communication with said cylinder volume, wherein said breast cup applies said pressure to said breast.
A breast pump for expressing breast milk from a breast, the pump comprising:
- a pressure source for generating a positive pressure and a negative pressure;
- and
- a controller operably connected to the pressure source, wherein said controller adjusts said positive and negative pressure and adjusts a cycle time between application of said positive and negative pressure to said breast.
A breast pump for expressing breast milk from a breast, the pump comprising:
- a pressure source for generating a pressure;
- and
- a controller operably connected to the pressure source, wherein said controller adjusts said pressure and adjusts a cycle time between application of said pressure to said breast, and wherein said controller generates a wave signal in response to said pressure and said cycle time, and controls said pressure source in response to said wave signal.
A drive system for an expandable volume of a breast pump, the system comprising:
- a motor having a first rotary output;
- a first gear system operably connected to said motor;
- and
- a second gear system operably connected to said first gear system and the expandable volume, said second gear system having a rack gear and a pinion gear operably connected to said rack gear,
- wherein said first rotary output is provided to said second gear system,
- wherein said first gear system adjusts said first rotary output provided to said second gear system to a second rotary output, and
- wherein said second gear system translates said second rotary output to a linear output.
A breast pump for supplying a pressure to a breast cup, said pump comprising:
- an expandable volume in fluid communication with said breast cup to supply said pressure;
- a motor having a first rotary output;
- a first gear system operably connected to said motor;
- and
- a second gear system operably connected to said first gear system and said expandable volume, said second gear system having a rack gear and a pinion gear operably connected to said rack gear,
- wherein said first rotary output is provided to said second gear system,
- wherein said first gear system adjusts said first rotary output provided to said second gear system to a second rotary output, and
- wherein said second gear system translates said second rotary output to a linear output.
