Abstract: A simulating training device for assessment of cervical dilatation is provided. The device includes a supporting platform, a rotating plastic drum rigidly connected to a shaft and having a plurality of rubber-lined holes of varying diameters, a box which covers the rotating drum and has an opening, an indexing mechanism which has a spring-loaded lock and a slotted indexing wheel, a turn wheel which has an indication arrow, and a scale which identifies a diameter of each of the plurality of rubber-lined holes. Rotation of the turn wheel and the slotted indexing wheel causes one of the plurality of rubber-lined holes to be positioned in the center of the opening of the box one at a time. The turn wheel, the rotating drum and indexing mechanism are synchronized such that the indicating arrow of the turn wheel points to the diameter of the positioned hole on the scale.

Abstract: A caliper to measure foot length and corresponding category of birth weight group by four colors used on the measuring scale namely. Green as normal, yellow as low, orange as very low and red as extremely low birth weight is devised for the first time to be used at the community level. A metal caliper with concavity to accommodate convexity of the heel and sliding device perpendicular to the scale to touch the longest toe fix the two extreme ends. Thus direct measurement is possible between two extreme ends of the foot.
