A blood container for storage of blood and blood components is disclosed. The invention comprises a blood container and a multiple blood bag system which includes a donor bag and one or more satellite bags connected by flexible tubing. The blood bag is made of polyvinyl chloride (PVC) plasticized with a blend of plasticizers comprising a plasticizer resistant to blood extraction such as a triester of trimellitic acid and a 7-10 carbon alcohol and a blood extractable plasticizer such as a dioctyl...

A pair of syringes respectively coupled by way of a pair of three-way valves to a source of blood and a source of reagent, so that withdrawing the plungers fills the syringes respectively with blood and reagent. The three-way valves are switched and a motor mechanism is activated simultaneously to move the plungers into the syringes to move the blood and the reagent through a pair of chambers separated by a semipermeable membrane. A selected substance in the blood is dialyzed through the membran...

A method of using whole animal blood, or a selected fraction of it, is disclosed as a suitable fluid for assisting recovery of petroleum from a reservoir. Bovine or other animal blood recovered from meat slaughtering is pumped into an oil reservoir from an injection well. It is injected either as a solution with flooding water or followed by water after injection in undiluted form. If desired a clotting retardant, such as citric acid or EDTA (ethylenediaminetetraacetic acid) may be added to the ...

A container for blood is provided in which blood received from a patient can be stored and processed without the necessity of being transferred to another container. For example, the blood can be centrifuged, frozen or transfused without the necessity of being transferred to another container. The container comprises a closed annular flexible container of a flexible material which is inert to blood and which is provided with at least one opening for the passage of blood into and out of the annul...

This invention relates to a pump for an "artificial kidney machine", or hemodialysis device; and primarily is designed for the pumping of blood for purification in such a system using the recently announced procedure of "single needle" dialysis, whereby a single needle is temporarily inserted into a vein or artery of a patient through which blood is withdrawn from the vein for purification and returned to the patient through the same needle. Such a dialysis system requires, in addition to the fi...

Device for treating blood comprising an elongated tubular member of semi-permeable membrane defining a blood flow path, a pair of membrane supports extending adjacent the path on opposite sides of the membrane, each support having a series of protuberances extending longitudinally of the support and spaced across the width of the support, the protuberances of one support being spaced between and overlapping the protuberances of the other support to cause the tubular member to assume a zig-zag fo...

Equilibrator device for use in determination of the acid-base status, the oxygen dissociation curve of blood and other properties of physiological interest. The device comprises, within a confined and thermostatically controlled environment, a cuvette for accommodating a sample of blood or other liquid to be equilibrated with a gas phase, means for controlledly rotating such cuvette and means for promoting passage of a gaseous flow firstly through a humidifying ambient and then into the presence...

A hemodialysis apparatus that carries out hemodialysis treatment by measuring or calculating the blood volume or its volume change as a blood indication level, and by controlling dialysis conditions according to said target blood indication level, wherein the chronological course of said blood indication level is defined as a target control line, and the primary blood volume (BV.sub.0) can be calculated as blood indication level. In the former part of the dialysis operation, the water removal is...

It is an object of the present invention to realize a small and light blood pump that can control thrombosis and moreover, endure a prolonged use. A blood pump comprising an impeller, a casing having a suction inlet and a delivery outlet and rotatably encasing the impeller, a magnetic drive means for rotating the impeller by magnetically acting from outside of the casing on a magnet that the impeller includes, a magnetic attraction force adjustment means for adjusting the attraction force by sai...

A blood reservoir being capable of reducing damage to blood stored therein. The blood reservoir has a housing in the form of a box, and filtering and defoaming devices provided in the housing, i.e., a device for filtering and defoaming on blood suctioned from a surgical field (outside a heart), a device for filtering and defoaming on blood vented from the interior of the heart, and a device for filtering and defoaming on blood drawn off from a large vein. The vented blood flowing into the blood ...
