    摘要： Sample collection for the Pap smear sample is critical for accurate diagnosis. Improper sample collection, poor sampling, and/or cell preservation can render a Pap smear unsatisfactory for evaluation, requiring a repeat smear collection. If the Pap smear does not contain appropriate representative cells from the transformation zone and endocervical canal, the ability of the test to detect disease is very low. Likewise, if the preservation of the sample is compromised, the screener's ability to recognize abnormal cells is greatly diminished. It is generally understood that cervical samples should be harvested by a two-stage technique, which includes sampling of the endocervical canal with a cytobrush and obtaining a sample from the transformation zone with a spatula. The use of either the cytobrush or the spatula alone may be adequate but not as effective as the two-stage technique. Both the Cervex Brush and REG;(Unimar, Inc.) and the Accellon Combi & REG;(Medscand AB) are two collection devices which combine the action of the cytobrush and spatula, thus permitting broader sampling with a one stage technique. The standard method of transferring cervical cells from the collection device or complete transfer of the collection device into the liquid collection vial is often challenging. These challenges include but are not limited to: 1-spilling the sample, 2-dispersing the medium collection such that air born body secretions could contact unprotected health care workers, 3-missing the collection container and contaminating the sample. It is the goal of the current device embodiment to provide a simple and consistent method of transferring the entire collection specimen into the collection container to maximize cell collection while minimizing challenges of head disengagement. Such devices are not limited to the cervical cell cytology collection markets but extend to all cell collection methods were the entire sample is suspended in a liquid or similar medium. Such samples include oral cavity collections (throat swabs, vaginal cavity collections (STDs, pregnancy test), urethral cavity collections (male STDs) fornex collections (Alaph fetal protein), and rectal collections as well as open procedures requiring cell sampling.

    摘要： A cannula arrangement includes a cannula member and a blunting member. The cannula member includes a hollow elongated member having an opening formed therethrough, and a puncture tip formed at an end of the hollow elongated member. The blunting member is adapted to move relative to the cannula member, and a portion of the blunting member or the entire blunting member is positioned inside the hollow elongated member. Moreover, when a fluid flows between an interior surface of the hollow elongated member and an exterior surface of the blunting member, such as when the puncture tip penetrates a vein of a subject, the fluid is visible via the opening.
