Abstract
The present invention provides a intravaginal collection device for the collection of vaginal discharge. The present collection device comprises a first layer that allows the passage of fluid therethrough but substantially prevents the passage of tissue and blood cells therethrough. The perimeter of the first layer is attached to a resilient rim. The rim is sufficiently resilient to provide an outward resilient force suitable to maintain the device in position within a user's vaginal canal during use. The device also comprises a second layer attached at its perimeter to the resilient rim. The second layer is suitable to substantially prevent the passage of fluid therethrough. The device further comprises a fluid retention layer positioned between the first layer and the second layer. The fluid retention layer is suitable for retaining fluid passed through the first layer. Tissue and blood cells are collected at the first layer of the present device, while vaginally discharged fluids are retained by the intermediate fluid retention layer. Vaginally discharged tissue and blood cells collected by the present device can be easily transported to health care professionals for pathologica…
