Device for checking the return of fluids built into a breast pump

摘要

The device has a bottle and a breast shield having a nipple at an end portion, where the breast shield is arranged for receiving a non-return valve (3). A support unit (4) surrounds the non-return valve and projects beyond an end of the non-return valve to ensure protection of the valve and full protection against accidental contact with fingers of a user. The support is positioned relative to a sleeve portion (2c) formed in the interior of a base (2a) of the breast shield, where the support is positioned at a height to provide overflow protection to the valve.
