Abstract
Abstract A device for measuring negative sucking pressure in infants, the device consisting of a baby bottle with a tight screw cap having a rubber nipple mounted thereupon, the nipple having a conventional small opening therethrough; there also being a hollow tube fitted eccentrically through the cap, the outer end of the tube being open while the inner end of the tube, located within the bottle, has a rubber balloon fitted thereupon, so that when the baby sucks on the nipple, a negative pressure is created in the bottle thus causing the balloon to expand, the size of which can be measured against a calibrated scale on the side of the bottle.
