The present invention describes a device for placement in the thoracic cavity of a patient. The toothbrush kit may include a brush head connected to a cap by a neck and a handle removably attached to the cap, where the handle includes a tooth paste container. A portion of web page content relating to a web page intended for display on the client system is received. An air jet is provided for creating the blast of air, the mouthpiece of the air jet being directed towards the mandrel in the opposite direction to the transport direction of the sleeve. The locking spool is rotatable between a first position in which the first face is adjacent the toothed hub, thereby locking the tool head in a selected angular position with respect to the handle, and a second position in which the second face is adjacent the toothed hub such that the tool head is pivotable about the pivot.
