摘要
An improved double handhold to prevent urine-test cheating. The device restrictively engages each of a subject's hands so that neither is free to insert a false specimen into a container. The container is housed in one of the two hollow, single-handhold units that assemble end-to-end to form the double handhold and enclose the container. Before separating the two units for access to the container, the subject grasps each handhold and does not let go until after voiding and reassembling the device. Each handhold unit has contact sensors to detect one hand's engagement. An assembly sensor on each unit detects its separation from the other unit. A signal on each unit indicates any breach of hand restriction that occurs while the units are separate. The subject, therefore, can not secretly use a hand to insert a false specimen. Previous handhold apparatus used a latch system to require hand engagement to separate and reassemble the units. Latch systems indicate a breach of hand engagement by mechanically blocking the reassembly. Latch-system handholds are costly, less convenient for voiding, risk injury to the subject, less reliable in operation, more difficult to keep clean, more subject to cross-contamination, not instantaneous in action, and easier to circumvent. The improved device solves these problems and makes the double handhold practical and affordable.
