Abstract: The extension set has two lumen for conveying an intravenous liquid and a drug through a common connector to a catheter for direct infusion of the drug to a patient. The lumen are connected in common to the connector or may be separated by a partition wall. In other embodiments, the drug carrying lumen can be disposed within the intravenous tube and may be of micro-bore size.

Abstract: A pump-actuated sequencing valve for sequentially administering, to a patient, two fluids contained in separate respective reservoirs, wherein the fluid is pumped from a first one of the two reservoirs by means of a pump associated therewith. The valve comprises a first portion connected to the first reservoir, a second portion connected to the second reservoir, and a third portion connected between the first and second portions, on the one hand, and the patient, on the other hand. The second portion includes a ball valve which is pressure-responsive to operation of the pump for blocking flow of fluid to and from the second reservoir, thus blocking both forward flow from the second reservoir and backflow from the sequencing valve toward the second reservoir.

Abstract: A connection system for respirator or anesthesia units with a Y-piece including an inhalation hose socket, an exhalation hose socket and a connector attachment piece as well as a tubular connector, connectable with the connector attachment piece, having a tube attachment for an endotracheal tube at one end, and at its opposite end a continuous annular groove in its exterior circumference, the connector attachment piece including a spring biased fastening member provided transversely to the longitudinal axis of the connector attachment piece for elastically engaging the annular groove under spring action. The connection system further includes a hand-operable unfastening mechanism for overriding the spring action of the fastening member, and the fastening member includes a lever having inner and outer arms, a pivot and a spring-loading member for the outer arm.

Abstract: An inflatable cholangiocath (10) includes an elongate shaft (11) having a proximal and a distal end (12,14), a second shaft (15) carried at the distal end and having left and right branches (16,18) adapted to be inserted into an incised duct of a patient and a central drainage lumen (24) extending from the proximal end, through the elongate shaft, and out the left and right branches, balloon means (30) encompassing a portion of the distal end and the left and right branches, the balloon means being closed to the central drainage lumen and, means for selectively inflating and deflating (20) the balloon means within the duct for predetermined periods of time.

Abstract: In an organism having a vascular system, a device and method for diverting blood flow from one blood vessel to another, such as from the hepatic artery to the portal vein for reducing hypertension of the liver. The method includes the implantation of a device according to the invention by which blood is diverted. A conduit is inserted within one vessel, normally a vein, and blood diverted to the conduit from another vessel such as an artery, wherein the blood is mixed.

Abstract: A positioning device for use with a tracheal tube which is insertable into a patient's trachea particularly a tube of a type which includes a respiration gas jet discharge which must be accurately positioned in respect to the first bifurcation of the trachea for optimal respiration effects. The positioning device comprises an elastic measuring probe which is insertable into the tracheal tube and has a distal end which may be projected out of the tube and which carries a carina engaging stop end in the form of outwardly foldable elements which may engage over the top of the carina on engaging the carina in a roof-like manner. The measuring probe includes an opposite end which may be manipulated by a person's hand to regulate the amount of extension of the lower end of the probe beyond the end of the tracheal tube which is inserted into the person's trachea.

Abstract: A catheter for puncturing blood vessels, particularly for vein punctures for hemo-dialysis. A section is insertable through a puncture opening into a blood vessel and a hose line following thereafter. The arrangement is in form of a double catheter in which two single catheters are associated for relative lengthwise movement by means of a longitudinal guide.
