Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

A removal device (121, 221) for removing and disposing of a pen needle (113, 213) connectable to a drug delivery device (111, 211) includes a body (123, 223) having a cavity (141, 241) for receiving the pen needle of the drug delivery device such that a patient end (116, 216) of a needle (115, 215) of the pen needle is covered by the body. An ejector (151, 251) is movably connected to the body (123, 223) for engaging the received pen needle (113, 213) and selectively ejecting the engaged pen needle from the body. The pen needle (113, 213) is securely retained within the removal device (121, 221) without exposing the needle (115, 215) of the pen needle until the pen needle (113, 213) can be properly disposed of, such as in a sharps container, thereby substantially preventing an accidental needle stick.

A hydraulic cylinder assembly system preferably includes a seal installer tool, a piston puller tool and a barrel ring. The seal installer tool includes a tapered ring and a piston plug. The piston plug is inserted into the piston and seals slipped over the tapered ring. The piston puller tool preferably includes a piston rod engagement member, a thrust bearing retainer, a thrust bearing, a draw rod and a barrel end retainer. The thrust bearing is retained in the thrust bearing retainer and one end of the draw rod is retained in thrust bearing retainer. One end of the piston engagement member is threaded into the thrust bearing retainer. An opposing end of the piston engagement member is threaded into a piston rod. The barrel end retainer is threaded on to an opposing end of the draw rod. The barrel ring is attached to a barrel of a water pump.

A method for replacing a tag tool needle includes securing at least a portion of a tag tool needle coupled to a tag tool in a needle container; and removing the tag tool needle from the tag tool with the needle container. A tag tool needle container includes a first tubular aperture adapted to receive at least a portion of a first tag tool needle therein, where the first tubular aperture has a compression-fit adapted to securely enclose the portion of the first tag tool needle when urged over the first tag tool needle; and a second tubular aperture coupled to the first tubular aperture and adapted to receive at least a portion of a second tag tool needle therein, where the second tubular aperture has a compression-fit adapted to adapted to securely enclose the portion of the second tag tool needle when urged over the second tag tool needle.

A uniquely designed torque wrench having a torque body, the torque body attached to a frictional squeezing clamp, and a lug socket which is rotationally connected to the frictional squeezing clamp. The frictional squeezing clamp entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder, the lug socket turning the wing nut of a hammer union.

A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

A treatment assembly for a drain is provided. The treatment assembly includes a skirt configured for covering the drain and a basket assembly configured for being received beneath the skirt and between an opening of the drain. The basket assembly contains a treatment material for providing treatment to the drain. A related method is also disclosed.

Systems, dressings, and related methods, for providing reduced pressure to a tissue site on a patient are presented that involve using a self-contained reduced-pressure dressing. The dressing includes an absorbent pouch and an electronics pouch. The absorbent pouch has an absorbent for absorbing liquid from the tissue site, and the electronics pouch has a pump for applying reduced pressure to the tissue site through the absorbent pouch. The electronics pouch is removably coupled to the absorbent pouch such that the electronics pouch and absorbent pouch may be easily separated for disposal.
