Patent ID: 10149667

Abstract:
A cervical cells sampling device includes a tubular sleeve with a first opening and an opposing second opening, an elongate rod having a retractable part with a mounting tip enclosed within the sleeve and a handle section extending out from the sleeve through the second opening. A cell collecting construct with a resilient sheath is stretched to cap onto the mounting tip of the rod and the stretched resilient sheath is in a constant contracting state that the cell collecting construct and portion of the retractable part are allowed to project out, or retract into sleeve, through the first opening by moving the handle section. A stripping member is fabricated within the sleeve to detach the resilient sheath from the mounting tip upon retracting the retractable part into the sleeve up to a predetermined level and the resilient sheath resumes original form once detached from the mounting tip, while prodding the rod back into the sleeve pushes the construct out of the sleeve.
