Abstract: This application discloses an antenatal cell extracting device comprising a thin, flexible, plastic tube adapted for cervical insertion in a human female. A flexible closure is provided at the proximal end of the plastic tube, and passing through the flexible closure, the plastic tube and the distal end of the tube is a plunger. A valve in the form of a smooth ball, the diameter of which is greater than the diameter of the tube, is fixed to the end of the plunger, and, upon reciprocating movement of the plunger with reference to the tube, the valve is caused to open and close. Means are provided for causing fluid to flow through the tube when the valve is opened, such means, preferably taking the form of a syringe connection to the flexible closure.
