Oral fluid collection device

Abstract

An oral fluid collection device includes a plunger and funnel to simultaneously collect and split a single specimen into metered doses for drug testing. The device may be used with collection tubes for collection of the metered doses and later testing. The device, when used, drives the metered dose into the collection tubes and removes bubbles in the specimen to provide improved accuracy in testing.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit of priority from U.S. Provisional Application No. 63 / 179,780 filed on Apr. 26, 2021, the entire contents of which are incorporated by reference.TECHNICAL FIELD[0002]This invention relates to collection of fluids, and more particularly to devices and methods for the collection of oral fluid and methods for using a collection device for drug testing. In particular, the invention relates to a simultaneous split collection device that does not use a collection pad.BACKGROUND[0003]Drug testing has largely been relegated to blood and urine testing in the past due to consistency of results and detectability. In recent times, oral fluid testing has grown due to the benefits of being able to use a non-invasive testing method, advent of new technologies, ability to observe collection, testing at a point-of-care rather than in a laboratory, and shorter collection times that allow employees to return quickly to work.

Benefits of technology

[0006]The systems and methods in accordance with the invention address a need to simultaneously collect a single specimen by directing it into two tubes. This minimizes the time of collection and simplifies the collection process by reducing the number of devices used to simultaneously collect a specimen in a single oral fluid collection device.

[0008]The invention provides an oral fluid collection device that meets SAMHSA guidelines for drug testing by providing a metered sample of collected oral fluids for testing using a single collection device and separate collection tubes. The oral fluid collection device increases efficiency in specimen collection by collecting multiple specimens simultaneously using a single collection device, and by not using collection pads before splitting a specimen. The oral fluid collection device volumetrically collects multiples specimens of equal volume.

Problems solved by technology

These systemic problems limit a user's ability to correctly use the sample collection devices and the ability to provide a collected sample that conforms to collection guidelines.
