In a blood reservoir comprising a hollow rectangular container for containing blood therein, a projected portion is provided on one vertical side of the container that is remoter from blood inlet means and nearer to blood outlet means by projecting into the container space substantially from the intersection between the one side and a horizontal extension of the blood inlet.

A cardiotomy reservoir for separating air from blood including a housing having top, bottom and side walls and defining upper and lower cylindrical chambers. A defoaming element comprising an annulus of sponge material is disposed in the upper end of said lower chamber and extends around the periphery of the housing. The upper chamber includes a channel for directing blood to the sponge annulus whereby the blood flows through the latter to the lower chamber, the sponge annulus including an antif...

Cap for a reservoir (10), intended to be mounted on a reservoir having an external thread, of the type comprising an internal thread (16), a sealing gasket (42) and a labyrinth means (20) in a fluid passage between the threads and the inside of the cap, characterized in that the labyrinth means (20) comprises at least one intermediate accumulation chamber (34, 36) in the passage.

An accumulator-reservoir device in a liquid cooling system utilizes a piston and metallic bellows to separate system pressures that are high and low in relation to one another. A piston position indicator is used sensing less than the full piston stroke in a manner to yield an accurate quantity measurement without undue elongation of parts.

A blood reservoir, commonly used in a blood circuit with an artificial lung, includes a blood extraction line chamber provided inside a housing and having a blood extraction line connection port, the chamber temporarily accommodating blood from a vena cava received via the connection port, a suction line chamber provided inside the housing and having a suction line connection port, the chamber temporarily accommodating blood, drawn in during open-heart surgery, received via the connection port, ...

A venous reservoir is provided in which a blood inlet (42) is located at an inlet end (70) of the container (48) which extends upwardly with a fast rise and for a sufficient distance to allow the blood entering the inlet to enter a large volume and to expand rapidly. The top (74) of the inlet end wall (70) of the container communicates with a vent outlet (46) whereby a sharp decrease in the velocity of the blood flow resulting from its rapid expansion provides buoyancy to air in the blood causin...

A blood reservoir serves to remove air bubbles from blood and maintain a desired amount of blood in an extracorporeal blood circulation circuit. The blood reservoir has a blood inlet chamber having blood inlet ports, a blood storage chamber having a blood outlet port, and a blood debubblizer disposed between the blood inlet chamber and the blood storage chamber and extending the full width across the blood passage defined by the blood inlet chamber. A rib is held against the side of the debubbli...

A reservoir cap includes a cylinder portion of molded resin and surrounding an outer circumferential surface of an opening portion of a reservoir body, and a flat portion unitarily formed on the cylinder portion and closing the opening portion of the reservoir body. A transparent film is insert-molded to the outer surface of the flat portion. Descriptive characters are formed at an inner surface of the film. The film is made from the same material as the flat portion. It is therefore possible to...

A refillable reservoir, particularly an ink converter for a fountain pen, has a cylinder in which a piston is slidable, and an actuating device for displacing the piston for refilling the ink chamber. Without needing to be detached from the piston, the actuating device can be stored substantially within the length of the chamber. The actuating device can be a rod which is disengageable from and slidable through the piston. Alternatively the actuating device can be a flexible ribbon coupled to a ...

An intake manifold with vacuum storage for a vehicle engine defined by an integrally formed enclosure assembly for the manifold and for the vacuum storage. The intake manifold portion of the enclosure assembly defines a plenum space and a plurality of branch runners fluidly connected to an air inlet for providing air flow into the associated engine. The vacuum storage portion of the enclosure assembly defines a storage space for vacuum. A passageway extends between the plenum space and the vacuu...
