Abstract
Abstract A device for collecting a urine specimen, which is particularly adapted for females, is configured and adapted for use while the user is sitting on a toilet in the normal position for voiding. The device comprises a collector and a specimen container and selectively collects the clean, contaminant-free mid-stream portion of urine in the container. The urine specimen container is releasably secured to the collector at a bleed-off conduit extending from a collection exit in a uring receiving chamber of the collector. This exit is positioned in the chamber above a urine bleed-off exit in the conduit adapted for receiving and discarding the first-voided portion of urine at a controlled rate. The collection exit is remote from the bleed-off conduit exit, is shielded from urine splashing into the chamber, and is below a urine overflow exit in the chamber which leads to an overflow conduit. The chamber is preferably open topped and is adapted to be supported on the specimen container. A suitable handle extends radially outward from the chamber to facilitate holding the device in use. The handle and chamber configuration is symmetrical so as to be equally convenient for right-handed and left-handed users. The device is inexpensive, simple and disposable; and the chamber, bleed-off conduit, overflow conduit and handle can be integrally molded in a single operation. The specimen container and its lid can be separately formed. The entire structure is such that the lid can be easily sealed to the container after use and the collector thereafter removed and discarded.
