OBSTETRICS TRAINING AID

摘要

An obstetrics training aid (10, 30) comprising a chamber (12, 32) having an entrance opening (15) to simulate a vagina; a plurality of apertured elements (20, 40) having differently sized apertures (22, 42) of bell-like form therein in simulation of a cervix and representing the cervix at different stages of dilation; and means within the chamber for positioning behind said vagina-simulating opening (15) a selected one of said cervix-simulating apertured elements (20, 40). The vagina-simulating opening (15) is bounded by flexible, resilient, material (16) to define that opening as an elongate slit (15). A plurality of different cervix-simulating apertured elements (20, 40) can be provided on a plurality of independent plates (20) or on a single carrier plate (40) rotatably mounted within the chamber in the manner of a turret. In either case the distance between the vagina-simulating opening (15) and the selected apertured element (20, 40) may be varied. It is envisaged that with such a training aid (10, 30), trainee medical personnel can, by simulation, gain experience of a variety of obstetric conditions and delivery stages in accord with the perceived size of the selected cervix-simulating apertures (22, 42) as felt by the trainee's fingers inserted from outside the chamber through the vagina-simulating opening (15).
