Abstract: A balloon intended to be swallowed and to occupy a given volume of the stomach in the presence of other balloons of the same type in order to permit a weight reduction of an individual is made up of an envelope containing two substances capable of reacting chemically with each other and with water in order to form a gas permitting the inflation of the balloon. The two substances are isolated by a coating melting under the effect of human body temperature. Other applications may be foreseen for a balloon capable of inflating automatically under the effect of a predetermined temperature.

Abstract: A cardiotomy reservoir which employs an inner wall structure which defines a central receiving chamber. The receiving chamber wall is tapered inwardly to provide a smooth blood flow along an arcuate imperforate portion which extends from the top to the bottom thereof into the blood receiving chamber. Apertures in another arcuate portion of the wall member allow fluid communication between the receiving chamber and the blood treatment element. Blood flow directing means direct blood entering the inlet port of the device downward toward the bottom of the receiving chamber along the imperforate portion of the inner wall so that the inflowing blood does not splash and has low turbulence.

Abstract: A blood bag of the present invention comprises a blood collection container; a tube communicating with the blood collection container and provided with a blood collecting needle at its distal end; and a blood collecting tube receiving member attached to the tube detachably or movably along the tube. Before labels are stuck on, a blood collecting tube into which blood has been collected from this blood bag is not confused with another blood collecting tube into which blood has been collected from another blood bag, or after labels are stuck on, blood is not collected from another blood bag into a blood collecting tube in which has been stuck a label having the same as serial number as a label stuck on this blood bag, so as to avoid a danger that blood having an infectious disease is transfused for mistaking it for safe blood.

Abstract: The sample coupler device is used to connect a sample collector container to a pipe used to transport gases or liquids. The coupler device permits collecting of blood or intravenous fluid sample material without it becoming contaminated. The coupler's most significant feature is the combination of the conical snout on the housing containing the integral feeder tube so that the blood or intravenous fluid may be collected without utilizing any external needles. This is significant when the person to whom this intravenous feeding system is connected has been exposed to Acquired Immune Deficiency Syndrome, hepatitis or any other non-curable or potentially fatal malady.

Abstract: The dialysis apparatus with a single needle comprises a reversible pump (3) controlled by a program so as to provide, in the first rotation direction, for the removal of a predetermined blood volume outside the circulatory system of a patient (P), the treatment of said blood volume in an artificial kidney (4) and the discharge into an expansion chamber (5), as well as, in a reverse rotation direction, to provide for the return of purified blood towards the patient (P) after a second purification in the artificial kidney (1). The expansion chamber (5) under pressure is used both as a blood accumulation container and as a housing for measuring the pressure. Its capacity is 4 to 5 times more than the internal volume of the artificial kidney (4).

Abstract: The method and system for the extracorporeal or extravascular treatment of blood employs diethyl ether for killing HIV cells in the blood. In practicing the method with the system, blood is withdrawn from one arm of a patient through a tubing to a container, e.g. a syringe barrel, where the blood is exposed to vaporized diethyl ether, which has been vaporized by heating, thereby to enable the diethyl ether to strip the viral envelope away from HIV cells attached to macrophages and dissolve the lipid layers thereof thereby to kill the HIV cells. The blood with ether is then passed through a manifold where a vacuum is drawn on the blood to remove most of the ether from the blood. The treated blood is then returned by a tubing and needle to the other arm of the patient. A blood thinner or anticoagulant preferably is given first to the patient orally or intravenously.

Abstract: A simplified fluid separation method and device usable for various apheresis procedures, including plasmapheresis. At least one pump is utilized to draw a first fluid (e.g. whole blood) into a separation device. The separation device then operates to separate the fluid (e.g. whole blood) into first and second fluid fractions (e.g. a cell concentrate and blood plasma). The first and second fluid fractions are pumped from the separation device to separate first and second fluid fraction containers, both of which are positioned on a single weighing device, such as an electronic load cell. At least one of the fluid fractions is subsequently removed from its fluid fraction container and returned to the human subject or other fluid source. Weights recorded by the single weighing device are then utilized to calculate the actual weights of fluid and/or fluid fractions pumped by at least one pump during the procedure.
