A tamper evident cap assembly, more particularly a combination of vial and cap assembly, assures the integrity of a specimen and of the specimen collection process. The screw cap is locked to the screw threads of a vial, when the vial is empty, with one of two latches that are integral to the cap assembly and can lock the cap to the vial. The lock is broken in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody, a specimen is placed in the vial, following which the cap is locked to the vial with the other of the two latches, which is broken when received by a testing laboratory. A loop formed to encircle the vial is connected by a tether to the cap and slipped onto the vial. At least one restraining rib on the vial is spaced below the screw thread top and is sized to permit the loop to be forced upwardly thereover to be restrained from downward movement. In addition, a limiting flange on the vial is spaced below the screw thread and above the loop restraining rib sufficient to accommodate the loop, and is sized to limit upward movement of the loop. In a specific embodiment, latch staples extend from the cap which can be inserted into, and irreversibly lock with, respective hasps extending from the loop.

An air operated dock leveler is provided to selectively raise and lower a deck with an extendable lip. The deck includes a downwardly extending deck lift arm. An air lift assembly includes a single chamber, inflatable bag positioned between a stationary lower bag support and movable upper platform. A pull line is secured to the platform and the deck lift arm. When actuated, a blower inflates the bag and raises the platform. The pull line pulls the deck lift arm forward and raises the deck to an inclined position. When the blower is turned off, the ramp descends until the now extended lip engages the bed of a truck. After loading or unloading the trailer, the bag is reinflated to raise the ramp and retract the lip. The blower is then turned off, and the ramp descends to its stored position.

A wellhead assembly includes a wellhead housing with a bore and an annular lock groove on an inner diameter surface of the bore. A wellbore member is concentrically located within the bore of the wellhead housing, defining an annulus between the wellbore member and the wellhead housing. An annular lock ring is positioned in the annulus. The annular lock ring has an outer diameter profile for engaging the lock groove and is radially expandable from an unset position to a set position. An energizing ring is positioned in the annulus to push the lock ring outward to the set position as the energizing ring moves downward. A retainer selectively engages the energizing ring and limits axial upward movement of the energizing ring relative to the wellbore member, retains the annular lock in the set position, and prevents axial upward movement of the wellbore member relative to the wellhead housing.

A minimally-invasive tissue retrieval device includes a flexible, liquid-impermeable bag with wires attached to the interior surface by an attachment mechanism that releases the wires when pulled. The wires extend into the bag from opposing sides of the bag opening, down to the bottom of the bag. Ends of the wires extend vertically upward out of the opening and are attachable to a wire retracting element rotatably attached to a housing, such that rotation of the retracting element relative to the housing winds the wires about the retracting element, pulling them away from the interior surface, and upward towards the opening. The bag is insertable into a surgical cavity, where a tissue sample is inserted into the bag. Rotatably-retracting the wires cuts through the tissue, which can then be removed in sections through the opening positioned outside the surgical cavity to prevent the spread of tissue fragments.
