Abstract
A feeding device includes a fluid reservoir and a nipple configured to be attached to the fluid reservoir. The nipple includes a base portion and a teat portion, where the base portion and the teat portion together define an interior space of the nipple. The nipple also includes a removable flow valve configured to be positioned within the interior space of the nipple and an internal cavity between the removable flow valve and a wall of the nipple. The removable flow valve includes a central opening and at least one valve protrusion extending from a surface of the flow valve into the internal cavity. The removable flow valve is configured to adjust a flow rate of a fluid from the fluid reservoir into the internal cavity.
Claims17
A feeding device comprising:
- a fluid reservoir;
- a nipple configured to be attached to the fluid reservoir;
- wherein the nipple comprises:
- a base portion;
- a teat portion;
- wherein the base portion and the teat portion together define an interior space of the nipple;
- an annular groove extending about an internal surface of the nipple;
- a removable fluid flow valve configured to be positioned within the interior space of the nipple,
- wherein, when the removable fluid flow valve is positioned within the interior space of the nipple, the removable fluid flow valve is directly positioned within the annular groove;
- wherein the removable fluid flow valve comprises a proximal surface;
- an internal cavity between the removable fluid flow valve and a wall of the nipple;
- wherein the removable fluid flow valve comprises:
- a central opening having a diameter in a range of 0.1 mm to 0.32 mm;
- and
- at least four protrusions extending from the proximal surface of the removable fluid flow valve into the internal cavity;
- wherein, when the removable fluid flow valve is positioned within the interior space of the nipple, the central opening is configured to control a flow rate of a fluid from the fluid reservoir into the internal cavity.
