    摘要： An artificial chamber including a first conduit, a second conduit, a third conduit, and a wall defining a space; in which the first conduit and the second conduit are positioned opposite one another; in which the third conduit is opposite the wall; and in which the wall has a concave surface is disclosed. The chamber can be part of a system for providing pulmonary support. The system includes the chamber and a first pump connected to the third conduit, and connected to a fourth conduit; in which the chamber receives fluid via the first conduit and the second conduit, in which the first pump receives fluid from the chamber via the third conduit; and in which the fourth conduit transports fluid from the first pump to a first blood vessel. Methods of making a chamber and a system, and methods of using the chamber and system are also disclosed.

    摘要： A manual clot aspiration and filtration system enables a method of removing a clot without general anesthesia and the expense of an operating room. An aspiration and filtration system for bodily fluid utilizes a syringe coupled with a filter unit to draw bodily fluid through the filter unit to collect debris on the filter. A flow valve may then be turned and the plunger depressed to force the filtered fluid back into the body. The filter may be configured to capture particles such as blood clots and plaque. The filter unit has a cover that can be removed for inspection and/or removal of the collected debris. When the cover is replaced, trapped air may be removed by turning the flow-valve to a purge direction and pressing the plunger into the syringe to force fluid back toward the filter unit to purge the trapped air through the purge valve.

    摘要： A blood pumping device having at least a first pump and a second pump, and a first and second pump actuating means for inducing a blood flow in a body's circulatory system is disclosed. Each pump comprises one upper chamber having an inlet channel and one lower chamber having an outlet channel. The upper and lower chambers are separated by a movable valve plane provided with a valve. The pump actuating means are configured to apply a movement to said valve plane in an upward and downward direction between said upper and lower chambers in response to control signals from a control unit, such that when said valve plane moves in an upward direction the valve provided in the valve plane is in an open position allowing a flow of blood from the upper chamber to the lower chamber, and when the valve plane moves in a downward direction the valve is in the closed position and blood is ejected from the lower chamber through the outlet channel. The bottom part of the bag portion has a shape that makes a turn of between 110° to 150° to cause blood entering the lower chamber to hit the stopping surface and come to a sudden stop, wherein the turn causes the flow of blood along the inner surface of the bag portion to abruptly change; and directs blood at the stopping surface to continue flowing along the outlet channel.
