Abstract
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.
Claims9
A device for facilitating the preparation of cytology slides, the device comprising
- a first cover having an inside surface;
- a second cover having an inside surface;
- an interposed spine, said first and second cover pivotably secured to the spine so as to be foldable into a book form capable of an open and closed position;
- an absorbent material mounted on the inside surface of the first cover;
- a filter, the filter overlays the absorbent material;
- and
- a cytology slide, wherein the cytology slide is removeably mounted to the inside surface of the second cover, the slide being positioned on the inside surface of the second cover to contact the filter when the book form is in the closed position.
A device for facilitating the preparation of cytology slides, the device comprising:
- a first cover having an inside surface;
- a second cover having an inside surface, the second cover hingeably attached to the first cover so as to be foldable into a book form capable of an open and closed position;
- an absorbent material mounted on the inside surface of the first cover;
- a filter, the filter overlays the absorbent material;
- and
- a cytology slide, wherein the cytology slide is removeably mounted to the inside surface of the second cover, the slide being positioned on the inside surface of the second cover to contact with the filter when the book form is in the closed position.
A method of preparing cytology slides, the method comprising:
- combining a cellular sample with a liquid-based medium to create a solution;
- extracting an aliquot from the solution;
- providing a slide preparation device comprising a first cover having an inside surface, a second cover having an inside surface, said first and second cover pivotably 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, the filter overlays the absorbent material and a slide attached to the inside surface of the second cover;
- applying the aliquot to the filter;
- closing the book form so that the filter containing the aliquot contacts the slide;
- and
- applying a manual pressure to the first and second covers.
