Problems solved by technology

However, these systems are also flawed in that they do not provide enough information to the medical staff to give them a complete and detailed understanding of the patient's condition and the operating status of the external support circuit

Embodiment Construction

[0016] With particular reference to these figures, the reference numeral 1 designates throughout the text a device for continuous monitoring of blood characteristic quantities in an external cardiovascular support circuit.

[0017] exist figure 1 A circuit is identified with reference numeral 2 in it, which may be used for example in ECMO, ECLS or CPB (Cardiopulmonary Bypass) therapy, comprising a venous line 3 that transports blood from the patient to an oxygenator 4, and along The venous line 3 arranges at least one pump 5 and the arterial line 6 returns blood from the oxygenator 4 to the patient. It is known that in ECMO and ECLS treatment, Circulation 2 supports the patient's functions and therefore works with him / her, while in CPB treatment, Circulation 2 completely replaces the patient's functions, so the patient does not need to play a role in removing carbon dioxide from the blood.

[0018] The oxygenator 4 comprises at least one blood inlet connected to the venous li...

Abstract

A device (1) for the continuous monitoring of blood characteristic quantities in an external cardiovascular supporting circuit (2), said circuit (2) comprising a venous line (3), an oxygenator (4), apump (5), and an arterial line (6), comprising: a sensor (7) suitable for the measurement of the venous saturation (SAT V) and a sensor (8) suitable for the measurement of the arterial saturation (SATA) of oxygen; a sensor (11) suitable for the measurement of the flow of blood (Qb) sent by the pump (5) to the oxygenator (4); a sensor (12) suitable for the measurement of the hemoglobin (Hb); dataentering means by the operator; an electronic control unit (14) provided with a microprocessor (15) and operationally connected to a display (16), and further comprising a sensor (19) suitable for themeasurement of the flow of work gas (Gf) and a capnometer (20) adapted to measure the concentration of carbon dioxide in the blood; wherein said microprocessor (15) is provided with means adapted tocalculate the quantity relating to the amount of carbon dioxide removed by the oxygenator (V'CO2ML) and the quantity relating to the amount of oxygen transferred by the oxygenator (V'CO2ML), the microprocessor (15) being programmed to display in numerical form on the display (16) the values of all the quantities measured and calculated and in graphic form at least some of said values, being further provided means for acquiring the quantity relating to the amount of carbon dioxide removed from the patient's lung (V'CO2NL) and the microprocessor being provided with means adapted to calculate thequantity relating to the amount of total removed carbon dioxide (V'CO2total).

Description

technical field [0001] The present invention relates to a device for continuous monitoring of blood characteristic quantities in an external cardiovascular supporting circuit. Background technique [0002] It is well known that during heart surgery, the main purpose of establishing extracorporeal blood circulation is to perfuse vital organs, that is, to spray them with oxygenated blood to ensure their normal functioning, and for this purpose, a device in extracorporeal circulation includes an oxygenator, said oxygenator The combiner enriches the blood output from the patient's venous line with oxygen, and then introduces it into the arterial line to return to the patient's body. [0003] In particular, eg for patients with acute cardiac and / or respiratory failure, external circulation can be used to support the function of the patient's organs. From a cardiovascular point of view, this external circulation is therefore designed to support the patient's vital functions. In ...
