    摘要： This invention relates to a device and system for cleaning the interior of conduits, gun barrels, or pipes, including drain pipes. The pipe cleaning device of the present invention is capable of (a) penetrating and removing restrictions that block flow, (b) scouring the interior wall of conduits or pipes to remove the buildup of undesirable solids that result in flow restriction, and (c) coating the wall of the pipe with a suitable substance. The present invention comprises a connecting member housed within a bendable or flexible conduit, a retraction handle attached to one end of the connecting member, and elastic or flexible strands attached to the opposite end of said connecting member. The strands are outwardly expandable in a radial dimension when said connecting member is retracted. The system of the present invention further comprises a pressure/suction source coupled to the conduit.

    摘要： This invention relates to an apparatus for inducing a pediatric patient to inhale a fluid pharmacological agent through a face mask. The apparatus comprises a fluid conduit through which fluid pharmacological agent may be inhaled, and a visual patient stimulator coupled to said conduit and accuatable by inspiratory or expiratory flow through said conduit. The visual stimulator of the present invention changes color in response to changing gas levels which occur during inspiration and expiration.

    摘要： A balloon-tipped suction catheter, for extirpating and aspirating tracheobronchial secretions from the trachea, endotracheal tube or tracheostomy tube and a method for using such catheter. The catheter preferably embodies an elongated tube with a cannula extending along the elongated tube. The distal end of the cannula communicates with an expandable membrane or balloon which is attached either to the walls of the distal end of the elongated tube or directly to the distal end of the cannula. Proximal to the expandable membrane are apertures which provide fluid communication between the exterior and interior of the elongated tube. A control port is provided at the proximal end of the catheter to control the transmission of suction through the catheter.In use, the catheter of this invention is inserted into an endotracheal tube, for example, to remove secretions. Positive end expiratory pressure ("PEEP") can be maintained by inserting the catheter through a "Y" connector assembly with a self-sealing diaphragm assembly. After the desired location is reached, the expandable membrane is inflated until it seals against the walls of the passageway. The control port is left uncovered until the membrane is inflated. The catheter is withdrawn and secretions are removed by the squeegee action of the balloon wall against the passageway wall and by aspiration.
