Endometrial sample collector

摘要

A non-invasive endometrial sample collector has an outer body of absorbent material configured for insertion into a vaginal cavity of a patient such that a distal end of the body is positioned proximate a uterine cervix of the patient. The collector has an internal collection assembly disposed within the outer body of absorbent material. The internal collection assembly includes a funnel having an opening at the distal end of the outer body configured to face the uterine cervix when the outer body is positioned in the vaginal cavity, and a reservoir in fluid communication with the funnel. During a menstruation cycle of the patient when endometrial tissue cells are shed within menstrual fluid that passes through the uterine cervix, or during any type of normal or abnormal bleeding episode, at least a portion of said fluid is directed to the reservoir via the funnel under the force of gravity.

主权项

1. An endometrial sample collector, comprising:
a body of absorbent material configured for insertion into a vaginal cavity of a female such that a distal end of the body is positioned proximate a uterine cervix of the female; and a collection assembly disposed within the body of absorbent material, the internal collection assembly comprising a funnel extending between an open first end and an open second end, the open first end having a larger circumference than the open second end, the open first end disposed proximate the distal end of the body and configured to face the uterine cervix when the body is positioned in the vaginal cavity, a conduit extending between a proximalmost end and an opposite distalmost end, the proximal most first end of the conduit attached to the second end of the funnel, and a reservoir attached to the distalmost second end of the conduit, wherein the funnel is configured to capture an endometrial sample comprising at least a portion of a menstrual fluid and endometrial tissue cells shed through the uterine cervix during the menstruation cycle of the female under the force of gravity and to direct said endometrial sample to the reservoir via the conduit, the reservoir configured to receive and hold said endometrial sample; wherein the conduit has a length greater than a length of the funnel and a length of the reservoir.
