Abstract: A device for purging gas bubbles from a liquid in which a wall is arranged to form a passageway, at least half of the wall being in the form of a hydrophobic porous membrane having a pore size between 0.01 to 30 Mu . The liquid flows parallel to the membrane in a passageway between 0.5 and 10 mm maximum thickness and the gas escapes through the pores. The membrane may be formed into a tube and may act as a connector between two lengths of piping, the gas escaping between the ends of the piping. In another construction the device is in the form of a sachet having an intermediate impermeable wall, the liquid being caused to flow parallel to the sides of the wall of the sachet.
Abstract translation: 一种用于从其中布置壁以形成通道的液体中吹扫气泡的装置，所述壁的至少一半为孔径为0.01至30μm的疏水性多孔膜形式。 液体在最大厚度为0.5至10毫米的通道中平行于膜流动，气体通过孔逸出。 膜可以形成为管，并且可以用作两段管道之间的连接器，气体在管道的端部之间逸出。 在另一种结构中，该装置是具有中间不可渗透壁的小袋形式，使液体平行于小袋的壁的侧面流动。

Abstract: DIALYSIS LIQUID WHICH HAS PASSED THROUGH A HAEMODIALYSER, IS REGENERATED BY ADDITION OF SODIUM HYPOCHLORITE. THIS CAN DEGRADE UREA AND OTHER NITROGENOUS IMPURITIES WITHOUT PRODUCING BY-PRODUCTS INCOMPATIBLE IN A DIALYSNG LIQUID FOR USE IN HAEMODIALYSIS. A DIALYSIS LIQUID OF RELATIVELY SMALL VOLUME CAN THUS BE CIRCULATED IN CLOSED CIRCUIT THROUGH A HAEMODIALYSER.

Abstract: A dialyzer, e.g., to act as an artificial kidney in which rigid or semi-rigid plates are stacked in pairs between supports, and have interposed pairs of semi-permeable membranes. First exchange zones are formed between the membranes and their adjacent plates which are provided with parallel ribs and grooves, and second exchange zones are formed between the membranes of a pair. In order to exert a constant pressure, a flexible-walled bag is located between the outermost plates and a support, over the projected area of the exchange zones.

Abstract: Apparatus and process for the concentration of a liquid containing non-ultrafiltrable elements, e.g. ascitic fluid in which liquid is fed to an ultrafilter having a membrane therein, and the concentrate and ultrafiltrate are withdrawn from the ultrafilter in which a pressure drop is induced in the concentrate by an auxiliary hydraulic resistance causing a pressure drop in concentrate which is proportional to the pressure drop exerted on the ultrafiltrate by the membrane in the inverse ratio to the ratio of the flow rates of the concentrate and of the ultrafiltrate.

Abstract: A peristaltic pump in which the material and thickness of the wall of the tube are chosen so that, at a predetermined pressure differential, between the exterior and interior, collapse of the tube wall to a flattened condition occurs, thereby causing restriction in the flow rate of liquid in the tube as a function of the pump inlet pressure.

Abstract: A duct for the removal of biological liquids, especially urine, in the form of a tubular body having internal and external surfaces, at least, of silicone elastomer. Near its upper end, e.g., for connection to a ureter, the body is surrounded by a woven or knitted textile sheath, which is secured by silicone elastomer adhesive to the body and is used as a suturing member for securing the duct to the ureter. Near its lower end the body is provided with a similar sheath or a radially outwardly projecting flange to secure it, e.g., to a bladder.

Abstract: An extracorporeal blood circuit in which a blood oxygenator is placed in series between a first and second pump, the pumps being of the peristaltic or ventricular type, the inlet to the first pump being connected to patient's vein and the outlet of a second pump to a patient's artery. The useful internal volume of the body of the first and second pumps varies substantially proportional to the pressure of the blood at the inlet, between minimum and maximum values, the maximum useful volume of the first pump and the minimum useful volume of the second pump being reached at a pressure of the blood at the inlet of the respective pump within a range of atmospheric pressure +/- 20 mm mercury.
