  • Cytological sampling method and device
    Patent number: 5533517

The sampling device includes a means for dislodging cytological material from the cervix uteri, a means for suctioning uterine cervical tissue under negative pressure, and a means for fixing collected cytological material. The sampling method and device is particularly useful for collecting cytological samples for morphological analysis and for collecting potentially HIV-infected cytological material without significant exposure to the healthcare worker.
