Problems solved by technology

[0006] These current machines or systems present several disadvantages, including: the substantially horizontal form of their support structure must accommodate the large volume of blood in diffuse extracorporeal circulation; the need for spatial Highly optimized; and possible hindrance to movement of healthcare professionals during surgical procedures
[0007] Another disadvantage is that the manual calibration of the position of the lobes of the peristaltic pump rotor relative to the type of tubing used is disadvantageous in terms of time consumption
Furthermore, since the manual calibration is inaccurate or even rather inaccurate, it requires very qualified professionals and in no way removes the presence of a margin of error

Embodiment Construction

[0018] With specific reference to these figures, the numeral 1 is used as a whole to designate a system for monitoring the extracorporeal circulation and perfusion of medical fluids during cardiopulmonary bypass.

[0019] The system 1 comprises a substantially vertical support structure 2 associated with at least one circuit 3 inducing blood circulation in a patient 4 undergoing cardiopulmonary bypass and equipped with at least one integrated pump supplying the medical The fluid is infused into the infusion circuit 5 of the patient 4 .

[0020] Specifically, a first integrated pump 6 is connected to the source inlet of a medical fluid 7, in particular of the type used in cardioplegia to cool the patient's heart during surgery, while a second integrated pump 8 is connected to the induction circuit The inlet of the circuit 3 is used to collect a predetermined amount of blood from the patient 4 .

[0021] The blood and medical fluid collected in this way are mixed together accor...

Abstract

The invention relates to an extracorporeal circulation and infusion system (1) applied to medical fluid in the cardiopulmonary bypass. The system of the invention comprises basically-vertical supporting structures (2, 21, 22, 23, 24) which can be correlated with at least a blood induced circulation loop (3) of a patient (4) and at least provided with one integrated pump (6,8) which is used for infusing the medical fluid into at least one infusion loop (5) of the patient (4) and designed to be applied together with a device(20) monitoring and controlling the induced circulation loop (3) and the infusion loop (5).

Description

technical field [0001] The object of the present invention is a system for monitoring extracorporeal circulation and perfusion of medical fluids during cardiopulmonary bypass. Background technique [0002] Before or during cardiac surgery with cardiopulmonary bypass, machines and systems are present for the perfusion of medical fluids and for monitoring the associated therapy, which generally include a support structure of substantially horizontal form equipped with A peristaltic pump associated with a segment of the infusion circuit applied downstream to the patient. Such machines or systems are generally capable of administering medical fluids such as those used for cardioplegia, which reduce the temperature of the heart organ during surgical procedures. [0003] A peristaltic pump is applied along a section of an infusion circuit and has a rotor member equipped with a peripheral pressure flap which can be manually adjusted relative to the center of rotation by a healthca...
