Breast pump with vibration unit and heater
A breast pump includes a housing including a first side and a second side. The first side and the second side define a cavity therebetween. The second side includes a concave surface defining a recess. The breast pump also includes a breast cup for engaging at least a portion of a breast including a nipple and an area surrounding the nipple. The breast cup is attached to the second side of the housing and positioned at least partly within the recess defined by the concave surface. The breast pump further includes a vacuum pump assembly, a container, a heater mounted to the housing, and a power source. The heater extends along the concave surface of the second side of the housing in thermal connection with the breast cup. The heater is configured to provide heat to the breast cup when the power source provides electrical current to the heater.
1. A breast pump comprising:
a housing including a first side and a second side opposite the first side, the first side and the second side defining a cavity therebetween, wherein the second side includes a concave surface defining a recess;
a breast cup for engaging at least a portion of a breast including a nipple and an area surrounding the nipple, the breast cup attached to the second side of the housing and positioned at least partly within the recess defined by the concave surface;
a vacuum pump assembly for applying a vacuum to the breast cup and at least the nipple of the breast;
a container fluidly connected to the breast cup for receiving milk expressed from the nipple of the breast;
a heater mounted within the cavity of the housing such that the housing is disposed between the heater and the breast cup, the heater comprising at least one heating element, wherein the at least one heating element extends along the concave surface and is mounted to the second side of the housing in thermal connection with the breast cup; and
a power source mounted within the cavity of the housing and connected to the heater, wherein the heater is configured to provide heat to the breast cup when the power source provides electrical current to the at least one heating element,
wherein the at least one heating element is configured to heat to a temperature and maintain the temperature, and
wherein the heat generated by the at least one heating element is configured to be transferred to the breast cup through the housing.
2. The breast pump as set forth in claim 1 , wherein the first side of the housing includes a convex surface, the housing being sized to fit within a brassiere such that the first side of the housing contacts the brassiere and the second side of the housing is proximate the breast.
3. The breast pump as set forth in claim 1 , wherein the at least one heating element is flexible and shaped to extend at least partly around the breast cup.
4. The breast pump as set forth in claim 3 , wherein the at least one heating element is a pair of heating elements that are spaced apart and mounted proximate to the breast cup.
5. The breast pump as set forth in claim 1 , further comprising a vibration unit that is mounted within the cavity of the housing and connected to the power source, wherein the vibration unit is configured to vibrate at least the breast cup when the power source provides electrical current to the vibration unit.
6. The breast pump as set forth in claim 5 , wherein the vibration unit comprises a motor, a rotor, and an eccentric weight connected to the rotor, the eccentric weight causing the housing and thus the breast cup to vibrate when the motor induces rotation of the rotor.
7. A pair of the breast pumps as set forth in claim 1 .
8. The breast pump as set forth in claim 1 , wherein the vacuum pump assembly is mounted within the cavity of the housing and connected to the power source, and wherein the vacuum pump assembly is configured to apply a vacuum to the breast engaged with the breast cup when the power source provides electrical current to the vacuum pump assembly.
9. The breast pump as set forth in claim 1 , wherein the heater further comprises an insulation material positioned on the at least one heating element opposite the breast cup.
10. The breast pump as set forth in claim 9 , wherein the insulation material is an insulation sheet positioned on a surface of the at least one heating element opposite the breast cup.
11. The breast pump as set forth in claim 1 , wherein the breast cup further comprises a connector that fluidly connects the breast cup to the housing.
12. A breast pump comprising:
a housing including a first side and a second side opposite the first side, the first side and the second side defining a cavity therebetween;
a breast cup attached to the housing and shaped to engage at least a portion of a breast including a nipple and an area surrounding the nipple;
a vacuum pump assembly for applying a vacuum to the breast cup and at least the nipple of the breast;
a container fluidly connected to the breast cup for receiving milk expressed from the nipple of the breast;
a vibration unit mounted within the cavity of the housing;
a heater mounted within the cavity of to the housing such that the housing is disposed between the heater and the breast cup, the heater comprising at least one heating element, wherein the at least one heating element extends along the concave surface and is mounted to the second side of the housing in thermal connection with the breast cup,
wherein the at least one heating element is configured to heat to a temperature and maintain the temperature, and
wherein the heat generated by the at least one heating element is configured to be transferred to the breast cup through the housing; and
a power source mounted within the cavity of the housing and connected to the vibration unit and the heater, wherein the vibration unit is configured to vibrate at least the breast cup when the power source provides electrical current to the vibration unit, and wherein the heater is configured to provide heat to the breast cup when the power source provides electrical current the at least one heating element.
13. The breast pump as set forth in claim 12 , wherein the first side of the housing includes a convex surface and the second side of the housing includes a concave surface, the housing being sized to fit within a brassiere such that the first side of the housing contacts the brassiere and the second side of the housing is proximate the breast.
14. The breast pump as set forth in claim 12 , wherein the at least one heating element is flexible and shaped to extend at least partly around the breast cup.
15. The breast pump as set forth in claim 12 , wherein the at least one heating element is mounted proximate to the breast cup.
16. The breast pump as set forth in claim 12 , wherein the vibration unit comprises a motor, a rotor, and an eccentric weight connected to the rotor, wherein the eccentric weight causes the housing and thus the breast cup to vibrate when the motor induces rotation of the rotor.
17. A pair of the breast pumps as set forth in claim 12 .
18. The breast pump as set forth in claim 12 , wherein the vacuum pump assembly is mounted within the cavity of the housing and connected to the power source, and wherein the vacuum pump assembly is configured to apply a vacuum to the breast engaged with the breast cup when the power source provides electrical current to the vacuum pump assembly.
