It sounds like you may be referring to a product called the SW Health Care Manual Breast Reliever, Model Number SWPBR01. This type of product is typically a manual breast pump used for expressing breast milk.

Without the cup or other specific attachments, it may involve using a handle or lever to manually create suction for milk expression.

Is there anything specific you would like me to do, such as provide more information about the product or guide you on how to use it? Let me know what type of assistance you need.
