Abstract: A cased suctioning catheter assembly with a protective flexible sheath around the catheter tube, has a thumb or finger operable pump located near the patient end of the catheter assembly. This pump receives irrigation fluid from a bag hanging on an IV stand and, when operated, pumps it into an irrigation lumen in the suction catheter on an as-needed basis during suctioning. Thereby one hand of the administrator can both stabilize the cross piece at the patient end of the suction catheter assembly and operate the irrigator, while the other hand controls vacuum flow as needed for the suctioning function.

Abstract: A sampling adaptor suitable for use in a unilimb breathing system with three or more hoses that includes a breathing hose connector, a swivel to allow the breathing hose connector to rotate freely in relation to the remainder of the adaptor, an angular swivel to allow adjustment of the angular shape of the adaptor, a filter that encloses the sampling end of a flexible sampling hose, a patient end connector, is disclosed herein.

Abstract: A stopcock with a locking connector protective assembly for selectively controlling the passage of sterile medicinal fluids from a plurality of sources and comprising a body having a plurality of input arms with male or female locking connector tips, an output arm with a male locking connector tip, a rotor located inside the body and having a handle and rotatable about an axis in the body and having a rotor lumen and having channels or holes that may be aligned with the arm lumens as indicated by pointers. A self-sealing injection port is provided which covers the rotor lumen. A locking connector protective assembly is mounted on the input arms to prevent touch contamination and may be retrofitted to current stopcocks, and retained by the locking connector tip. A telescoping resilient coil variably expands to enclose the locking connector tip when the tip is not in use and retracts sufficiently to allow access to the locking connector tip for connections to a complementary locking connector tip.

Abstract: One end of a tee adaptor connects to the proximal end of an endotracheal tube. The other end of the adaptor connects to one end of an elongate transparent flexible bag. The other end of the bag is attached to a catheter tube at a point remote from the adaptor and remote from the distal end of the catheter tube so the catheter tube is sheathed by the bag. A reed valve is between the distal end of the catheter tube and the adaptor connection to the endotracheal tube. The distal end of the catheter tube can be pushed through the reed valve and through the endotracheal tube into the lung for suctioning. The catheter tube has a lumen in its wall through which irrigation fluid is delivered to the distal end as suctioning occurs.

Abstract: Two tubes of flexible, resilient transparent material are introduced side-by-side into the oral cavity. The distal ends of the tubes are longitudinally spaced, so that the more remote end will enter either the esophagus or larynx before the more proximate distal end enters either passageway. A cuff adjacent the more remote distal end is inflated to seal the tube in the passageway. A collar is placed at the mouth and seals the tube at the mouth and is retained in place. A nose clip seals the nasal cavity. Air is introduced to the uncuffed tube. If it is thereby supplied to the trachea, ventilation is continued through that tube. If air is not thereby supplied to the trachea, air is supplied to the cuffed tube, which has entered the trachea, and ventilation is thereupon provided to that tube. Aspiration or administration of material can be provided through whichever tube is not supplying air to the trachea.

Abstract: A safe anesthetic mixture is supplied through a humidifier unit and passageway to a mask. The humidifier unit and passageway are incorporated in a device having an inlet nipple for connection to the delivery hose from a gas machine, a nipple for connection directly to a mask, and a nipple for connection directly to a rebreathing bag, with a common chamber therebetween, and a valved passageway and outlet nipple for connection to an exhaust line. The great majority of the exhaled mixture is removed through the rebreathing bag and exhaust line. Since very little of the anesthetic mixture is rebreathed, this device avoids the necessity for a carbon dioxide absorber.
