Abstract: The present invention relates to an integrated system for monitoring physiological variables in cardiopulmonary bypass process, which utilizes a transducer specifically intended to act directly on the cardiopulmonary bypass. Said system according to the present invention comprises at least two components, one is a CPB transducer and a minimonitor, coupled to each other by means of a cable and an electrical connector.

Abstract: The present invention provides automatic zeroing and electronic level adjustment of pressure transducer in relation to patient, applied to vital signs monitors, where the automatic zeroing of circuit of pressure consists of circuit and software able to remove the value of the virtual ground voltage from the pressure calculation, and the electronic level adjustment of transducer in relation to patient consists of compensating, through software, the value in mmHg related to level difference in cmH2O informed by the user by means of monitor interface.

Abstract: A novel artificial circulatory assistance chamber for various uses associated with cardiovascular procedures, having a rigid capsule with a base and a dome, with blood inlet connectors and blood outlet connectors, and respective one-way valves. The rigid capsule contains an impermeable membrane that divides the capsule into a blood compartment and an outer compressible compartment that is filled with a volume of gas/liquid.

Abstract: The present invention relates to a system comprising a flexible bag (8) for storing the drained secretion with an anti-collapse device (9), being connected on one side to a “T” valve (10) which is provided with protective lid (21) and, on the other side, to the flow control backflow preventer valve (1) consisting of a one-piece circular core (2) of elastomeric material which is secured to the housing (3), said core (2) containing a central plug (4) connected by radial rods (5) to the borderline (6) of the circular body thereof, so that said core (2) is used in two-way housings, an inlet (7) and an outlet (7?), said valve (1) composed of a one-way valve. Said system further comprising within the housing (3) a clot fractioning device (25) at the inlet and an anti-clogging device (26) from the maximum opening point of the core (2).

Abstract: The present invention deals with a new process and equipment for collecting and recovering residual blood from cardiopulmonary bypass, notably with the purpose of increasing efficiency in hemoconcentrators and hemodialysers. The present invention is advantageously employed, especially, for blood recovery after surgery or for hemodialysis, in addition to other applications employing this technique.

Abstract: Membranes are provided to be specially developed for use in chambers for artificial circulatory assistance which may be employed primarily in cardiovascular procedures, notably to produce arterial capacitance, to regulate blood pressure, to produce aortic counterpulsation and to pump blood. The membrane may have circular sections that may vary in size or not depending on the function to be performed and are interconnected so that the transition between one section and the other is smooth, regardless of the size of each section. Further, chambers and pumps may be used for cardiopulmonary bypass and a pumping system.

Abstract: A membrane valve for controlling flow and pressure relief has a format following the anatomy and the action mechanism of a sphincter, in order not to have restriction points to the fluid flow. The valve includes a body provided with terminal sections provided with ends and, internally, a folded membrane which opens and closes according to the flow and/or pressure exerted therein, directly or indirectly, locally or remotely.

Abstract: The present invention relates to improvements of valves of the cartwheel type, with receptive arrangements incorporating the valves, which comprise a component of elastomeric material in the form of a cartwheel fastened by means of the external ring to the valve case. The invention comprises a central plug connected by rods to the external ring and, normally, when used in two-way casings (with only one inlet and one outlet), the valve acts as a unidirectional valve. When used in a three-way casing, or a casing with more than three thereof, the valve can act to seal off and let through a flow of fluid on either side of the valve, alternately, depending on the fluid-circulation design choice.
