Abstract: A transfer bag apparatus is disclosed which is adapted to be used in the autologous transfusion of blood to a patient by collecting the blood from the collection bottle of a drainage device for the chest cavity of the patient. The transfer bag comprises a flexible bag, having means at one end of the bag to be placed in fluid communication with an infusion set to transfuse the patient with blood, and means at the other end of the bag adapted to be placed in fluid-tight communication with the interior of the collection bottle to transfer blood to the interior of the blood bag. The method of autologously transfusing a patient by means of the present invention involves collecting blood in the collection bottle, placing the transfer bag assembly in communication with the blood in the collection bottle, transferring the collected blood from the collection bottle to the transfer bag, and allowing the blood collected in the transfer bag to be infused into the patient.

Abstract: This invention provides a catheter for nasogastric intubation comprises a tube for nasogastric intubation and a plastic separator, said tube for nasogastric intubation consisting of a catheter and a plastic sheath tube having a longitudinal tear-off line over full length thereof together with elasticity and rigidity slightly larger than those of said catheter inserted slidably thereinto, and said separator for splitting said sheath tube fixing said tube at the vicinity of a nostril.

Abstract: A connection component suitable for use with an enteral fluid delivery set is arranged in the form of a replacement for the cap of a pre-filled, foil sealed fluid container. The connection component includes a fluid outlet passage which is arranged in the form of a projecting spike which penetrates and opens the foil seal as the connection component is attached to the pre-filled container.

Abstract: An enternal nutrition pump system operates in a cyclical manner with a period between cycles being selected in accordance with the desired fluid delivery rate. Each pump cycle may correspond to a single rotation of the rotor or a fractional rotation of the rotor. Rotor rotation may alternatively be sensed by utilization of magnetic sensors or by monitoring of the AC componment of current supplied to a DC motor driving the rotor.

Abstract: An angiographic catheter includes a relatively soft, tip portion having a preformed curvature, and a resilient body portion extending therefrom having a preformed curvature in the opposite direction. A lumen extends through the catheter for the injection of angiographic dye therethrough to the right coronary artery. The part of the body portion of the catheter which it in the aortic arch of the patient during use has an amount of curvature which is less than the amount of curvature of the aortic arch, so that the body portion of the catheter is resiliently deformed where it passes through the aortic arch. The deformation results in the biassing of the tip portion of the catheter into the ostium of the right coronary artery.

Abstract: A canister type of measuring and dispensing device wherein granular material is dispensed from a plurality of drawers and each drawer preferably has one open compartment and one closed compartment wherein the compartment dispenses a commonly used quantity of granular material and wherein each drawer is freely interchangeable with drawers having different dispensing dimensions.

Abstract: A cannula, such as commonly used for introduction of a catheter through the cannula into a body cavity, includes a plastic tube and an adaptor at one end of the tube. For easy removal of the cannula from around the catheter, the tube and adaptor are splittable along two or more longitudinal grooves or induction lines in the tube and adaptor. The induction lines are circumferentially spaced apart by an angle of 45.degree. to 180.degree.. Near the end of the tube opposite the adaptor, the induction lines in the tube are twisted, or extend circumferentially, providing increased stability of the induction lines to minimize premature splitting during manipulation of the cannula.

Abstract: A device for automatically administering predetermined amounts of medication from a syringe through a conduit to a patient is described. This device includes an automatic flushing mechanism which flushes the medication from the conduit after the completion of the medication dosage using a flush syringe containing a flush solution. A force derived from a spring is used to expel the medication and the flush solution from their respective syringes. Thus, the patient is insured a full dosage of prescribed medication without the need of continuous attention by hospital staff.

Abstract: An autotransfusion device usable with a chest drainage unit includes a collapsible fluid collection bag assembly having pliable fluid collection bag, a pair of stiffener members adjacent the opposed sides of the bag, and an enclosure sealingly connected to the bag securing the stiffeners in place. A fluid inlet, gas outlet, and a blood outlet are connected to the bag. A holder is dimensioned to compress the opposed edges of the bag assembly to cause the stiffeners to bow outwardly in opposite directions and expand the collection bag.

Abstract: The angiographic catheter includes a long generally flexible portion of a first material, an intermediate portion of the first material and a second material that is more flexible then the first material and a tip portion of the second material. The long body portion has a first exit opening having a stream trajectory directed toward the exit stream trajectory from the tip member exit for stream breakup and mixing at. A reaction exit is directed in the opposite direction of the first exit opening.The generally long body portion with a curved end portion with a first end curve of generally circular shape about a center that is connected to the end of the long body with a compound curve connected to the end of the first end curve and having a member positioned generally parallel to the long body portion with the distance between parallel members generally less than to the radii of the generally circular shape.

Abstract: An essentially leak proof urine collection device to be worn by a female which can be easily and comfortably positioned. The device is basically a receptacle, essentially semi-ovoid in shape, having an ovoid-shaped opening defined by a rim portion to which is attached an encapsulated deformable polymer gel ring which, when in use, substantially conforms itself to the contours of the vulvar tissue contacted by the gel, thus forming an essentially leak proof seal.

Abstract: A suction tube is adapted to receive an enteral feeding catheter through its lumen and has a longitudinally splittable wall to allow the suction tube to be removed from a patient while leaving the feeding catheter in place. In a modified embodiment, the suction tube has a second longitudinally extending lumen in the wall thereof which may be used for air bleed, sample aspiration and delivery of medication.
