LABOUR DELIVERY MODEL

Cervix Vaginal Dilation Modules can be Inserted into the Advanced Childbirth Simulator. This Model consists of six development phases and each part shows a state of prenatal cervix and birth canal. Labour Delivery model demonstrates the five labour stations, relations between the scope of expanding of the orifice of cervix and the range of cervical tunnels, as well as the relation between the position of the head of fetus and the square of ischial spine.Five Labor Stations, Selected to represent conditions of the Cervix and Vagina prior to labor, during labor, and at Birth in a Primigravid Woman Stations may be placed in Birth Canal of Advanced Childbirth Simulator.

Labour Stations illustrated are:

STA -5 prior to onset of labor: The orifice of cervix has no expanding and the cervical tunnels haven't disappeared at all. The positional relation between the head of fetus and the square of ischial spine is -5.

STA -4 cervix Partially Effaced: The orifice of cervix has expanded 2cm bigger and cervical tunnel disappear 50%. The positional relation between head of fetus and the square of ischial spine is -4.

STA -3 cervix Fully Effaced:The orifice of cervix has expanded 4cm bigger and the cervical tunnels disappear absolutely. The positional relations between the head of fetus and the square of ischial spine is -3.

STA +2 Cervix Nearing Full; dilation.

STA 0 fetal head at plane of ischial spine: The orifice and cervix has expanded 5cm bigger and the cervical tunnels disappear absolutely. The positional relation between the head of the fetus and the square of ischial spine is 0.

STA +5 crowning of Fetal Head Labor Delivery Module.
