This invention relates to a pacifier that may properly interest an infant of eight months old or older to make a preferable stimulation, for leading the infant to the next developmental stage of ingesting activity, or that can be used in a way for adapting to more advanced ingesting activity. A pacifier is provided with a nipple ( ) and a shield plate ( ) disposed at the base portion ( ) of the nipple which has a predetermined width. The nipple is provided with a tip portion ( ) having a width and a thickness, the width being larger than the thickness, to be formed into a flat shape, and an upper curved surface ( ) formed at the upper surface of the tip portion so as to be convex at a central portion thereof.

This invention provides an artificial nipple . The artificial nipple comprises: a nipple portion having a first curved surface, whose tip is provided with an opening portion ; a nipple body portion formed on the nipple portion , having a second curved surface, wherein the second curved surface of the nipple body portion is continuously extended from the first curved surface of the nipple portion , and wherein the second curved surface of the nipple body portion is significantly expanded as a part of the second curved surface goes away from the nipple portion ; and a base portion formed on the nipple body portion, wherein the base portion is capable of being attached to a container to house a drink. According to the present invention, the nipple body portion has a maximum outer diameter of 30 mm or more. According to the present invention, the nipple portion , measured by placing the base portion of the artificial nipple on a precise universal tester having a metallic pressing top made of a cylindrical shape with a radius of about 5 mm, to compress the maximum outer diameter of the nipple portion into the direction of the center thereof, has a nipple elasticity of 0.1 N to 0.8 N when the maximum outer diameter of the nipple portion is compressed by 20%, and of 1.0 N to 2.5 N when the maximum outer diameter of the nipple portion is compressed by 60%.

Breast pump

Teeth correction toy

A breast pump for extracting milk from a human breast includes an extracting cup and has an engagement portion for engaging the breast. A container has a mouth portion connected to the extracting cup. A milk receiving bag is mounted to the mouth portion and suspended in the container. An air suction source is connected to the container in order to produce air suction inside the container. An air path connects the interior of the extracting cup and the inside of the container, wherein the air suction creates a negative air pressure condition to assist in the suction of milk. The milk flows by gravity through the extracting cup and into the milk receiving bag without contact with the air suction source or the inside of the container.

Breast pump having a pressure adjusting mechanism

A milking apparatus for extracting milk from a human breast has a funnel shaped receiver positionable over the breast attached to a conduit and receiver bottle for receiving extracted milk. An adaptor is provided such that different types of suction pumps may be used in conjunction with the apparatus in response to the needs of the user. A pressure adjusting mechanism is associated with the adaptor which is operated automatically or manually to relieve excess suction exerted by a selected suction pump on the breast.
