Device and method for cytology slide preparation
This invention provides a novel device and method for preparing cytology slides. The device comprises a book-like form including an absorbent material and filter attached to the inside surface of a front cover and a cytology slide removeably attached to an inside surface of a back cover. A sample is removed from the body of a patient, placed in a liquid-based solution, and then on the filter. When the book-like form is closed, the sample is effectively transferred to the slide. The device can be modified so that a plurality of slides are prepared at the same time.
1. A method of preparing cytology slides, the method comprising:
providing a slide preparation device comprising a first cover having an inside surface, a second cover having an inside surface, said first and second covers hingedly secured to each other so as to be foldable into a book form, an absorbent material mounted to the inside surface of the first cover, a filter overlaying the absorbent material and a plurality of slides attached to the inside surface of the second cover;
applying an aliquot of cytology sample to the filter; and
closing the book form so that the filter containing the aliquot contacts the slides.
2. The method of claim 1 , wherein the aliquot comprises a cellular sample in a liquid-based medium.
3. The method of claim 1 further comprising applying pressure to the first and second covers in the closed position.
4. A device for facilitating the preparation of a plurality of cytology slides, the device comprising:
a cover having an inside surface;
a base having an inside surface;
an interposed hinge, said cover and base hingeably secured by the hinge so as to be foldable into a book form capable of an open and closed position;
a plurality of absorbent material mounted on the inside surface of the cover;
a filter, the filter overlaying the absorbent material; and
a plurality of cytology slides, each cytology slide corresponding to one of the absorbent material mounted on the cover, wherein the cytology slides are mounted to the inside surface of the base, each slide being positioned on the inside surface of the base to contact the corresponding absorbent material and the filter when the book form is in the closed position.
5. The device of claim 4 , wherein the slides are removeably mounted on the inside surface of the base.
6. The device of claim 5 , wherein the slides are removeably mounted to a slide carrier, the slide carrier is removeably mounted to the inside surface of the base.
7. The device of claim 5 , wherein the slides are removeably mounted to a slide carrier, the slide carrier is hingeably mounted to the inside surface of the base.
8. The device of claim 4 , wherein the absorbent material is mounted to a strip, the strip is removeably mounted to the inside surface of the cover.
9. The device of claim 4 , wherein the filter includes a plurality of individual filters, each filter corresponding to one of the absorbent materials.
10. The device of claim 4 , wherein the cover is weighted to effectively transfer a sample applied to the absorbent material and filter to the slide when the book form is in the closed position.
11. A slide carrier suitable for use with the device of claim 4 , said slide carrier including a plurality of slots for holding a plurality of cytology slides, wherein the slide carrier is removeably mounted to the base of the device.
12. The device of claim 4 wherein the interposed hinge is formed by a spine interposed between the cover and base.
