## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. Provisional Application No. 62/009,233 filed Jun. 8, 2014.


FIELD OF THE INVENTION
The present invention relates generally to the field of washing devices, and more particularly to devices and methods of washing and sterilizing breast pump accessories and baby bottles.
BACKGROUND OF THE INVENTION
With so many new mothers in the work field today, the need to pump breast milk while away from the home has become more and more prevalent. Many new mothers who for different reasons are not able to breast feed their babies but still want their babies to get the benefits of breast milk have to use a breast pump at home or at work.
Ensuring the proper cleaning of the breast pump and accessories can be very tedious and inconvenient with existing devices. Having access to a method of cleaning the breast pump and accessories with portability, speed and efficiency would relieve the worry of having to find a hygienic way to clean these items after use.
To maintain good hygiene it is required to wash the pump accessories and bottles after every use. Washing all these parts several times a day could be very time consuming and tiring and damaging to the hands, it can be especially challenging to do at work. Hence, the need for an automated breast pump accessories washer.
There exists on the market general dish washers and table top dishwashers, but they are not well adapted for use in cleaning breast pump accessories, and do not have special disinfecting or sterilization features. Industrial washers are available at very high-cost and may have satisfactory sterilization capabilities, but such devices are designed for washing of laboratory bottles or other industrial equipment, and generally do not have design features to accommodate cleaning of breast pump accessories.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for cleaning breast pump accessories
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of devices for washing and sterilizing breast pump accessories and baby bottles.
In an aspect, the breast pump accessory washer includes a running water supply, a drain, and a power supply, and can easily be used when a sink/wash basin and a nearby power supply is available. The breast pump accessory washer can be portable and can easily be installed, by attaching an inlet nozzle to a faucet, connecting a power cord to a power outlet, dropping a drain pipe in a sink, and using the washer when needed.
In a related aspect, the breast pump accessory washer uses less power and water than the dishwasher and hence can be run several times a day without having to run the whole dishwasher to clean some bottles or to clean the baby bottles along with dirty dishes.
In another related aspect, a conventional domestic dishwasher sprays water only from the bottom, which can topple the breast pump accessories and does not allow for the water jet to reach inside the breast flanges and therefore does not clean the breast pump accessories well. This device washes the breast pump accessories more effectively in less time, and also allows sterilizing them with ease.
In yet a related aspect, the simple design of the breast pump accessory washer ensures that it can be manufactured at a low cost. Even when the washer is no longer needed for cleaning breast pump accessories, mothers can use this device to wash baby bottles and sippy cups, with the option of not using the sterilizing function.
There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.
