ABSTRACT:
FIELD OF INVENTION
This invention relates to collecting urine specimens for drug-abuse testing, specifically to apparatus that restricts a subject's hands to prevent cheating.
DESCRIPTION OF PRIOR ART
To prevent a false urine specimen, it has been necessary for an attendant to watch the subject urinate into a container. To avoid this violation of personal privacy, portable, two-hand-restricting container holders were proposed. These have not been practical because they were unwieldy, as can be seen from U.S. Pat. Nos. 5,223,221 (1993) and 5,603,903 (1997), both to Copelan.
To simultaneously restrict both hands from access to the container, the devices used two handles that were operated together in a combined mechanism. Necessarily, the handles were mounted as a pair on a single, crossbar-like part of the various devices. Both hands were restricted, but the devices were not acceptable. Their bulk was cumbersome. Holding on to the two handles was awkward. Voiding was further complicated by the container's required location, either attached inconveniently to the crossbar or in a separate section of apparatus. The contrivances were particularly impractical in the confined space of a lavatory.
ADVANTAGES OF PRESENT INVENTION
The present device is a practical means for restricting the hands when collecting a urine specimen, Several features are novel for a hand-restricting apparatus:
1. The entire device is a double handhold, a cylinder less than 25 cm. (10 inches) long. It is completely self-contained. No additional elements are necessary or desirable.
2. The double handhold consists of two hollow, single-hand units assembled together to enclose a container. The subject must have one hand engaged on each of the units to separate them, expose the container, and reassemble the device.
3. Each unit effectively restricts a hand. It is not necessary to yoke the hands together on a cumbersome crossbar or at a distance from the container.
4. The units are partly telescoped together to form the double handhold. This makes the joint secure and the device conveniently small.
5. One latch is sufficient to lock the device, but it has two. Thus, each unit can use an independent latch mechanism so that the units can be separated.
6. Separating the units frees the arms, and the container is easily positioned for voiding.
7. The container rests in one unit, which is held in the hand. Access is natural.
The assembled double handhold is about the size and shape of a tall water tumbler. It is convenient even in a small lavatory. It is not an encumbrance when preparing to void. After the units are separated, the subject's arms can move independently. Posture and balance are not disturbed. Voiding is almost as simple as with a container by itself.
