ABSTRACT:
An infant measuring and growth charting device having a substantially flat bottom base of a length and width to accommodate infants to be measured, a fixed head board, and a slideable locking foot board, the infant being place in the device, the foot board slid forward to touch the bottoms of the infants feet, the infants legs being fully extended, and the device locked into place. An embedded ruler is affixed into the upper surface of the bottom base, and a viewing hole in a portion of the sliding foot board, over the embedded ruler, follows, and displays the measurements of the infant, and when the exact measurement of the infant is displayed in the viewing hole, the foot board is locked into that position, and this exact measurement will be in the viewing hole for later recording, or, photographing. After the infant is removed from the measuring device, a T-square charting device is inserted into the same groove used to guide the moveable foot board. This charting device allows the user to insert a standard growth chart onto the device, align pertinent data values on the standard growth chart, with guide lines on a transparent cursor plate on the T-square, and holes being provided at the intersections of these guide lines allow a pencil, or pen, or marking device, to be inserted through the cursor plate, and onto the chart, to mark, and plot the several parameters involved in the growth of the infant in a very precise manner.
