Abstract

Abstract There is disclosed herein an aspiration and method of using same for obtaining cell samples from the walls of a body cavity and designed particularly for obtaining samples from the lining of the uterus. The device comprises a tubular member, fenestrated at one end and adapted for connection to a hypodermic syringe at the other end and a tubular sleeve over the surface of the tubular member which is moved from a position near said adapter to a position covering the fenestrae on the end of the tube, whereby fluids pulled into the tubular member through the fenestrae can be ejected from the end of the tube for study.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 199 words
A method of preparing endometrial samples for microscopic examination comprising: inserting through the cervix one end of a first elongated flexible tubular member having an ejector port at said end and having fenestrae through the tubular wall adjacent said (end) ejector port and having a second tubular member having an internal diameter approximating the external diameter of said first tubular member and being slidably coaxially mounted on said first member at a position spaced from the cervix, said second tubular member having a length at least that of the fenestrated portion of the first tubular member, and said first tubular member having a hypodermic syringe attached to the proximal end thereof; withdrawing the plunger of said hypodermic syringe causing a vacuum in said first tubular member and sucking cell samples from the endometrium through said fenestrae, withdrawing said first tubular member from the cervix, sliding said second tubular member over the fenestrae of the first tubular member, placing the fenestrated end of the first tubular member over a microscope slide while the fenestrae are under the second tubular member, and pushing the plunger of said syringe to eject said cell samples onto said microscope slide from said ejector port.
