Embodiment Construction

[0032] An oxygenator with negative pressure regulation function will be described in detail below with reference to the accompanying drawings.

[0033] Such as figure 1 Shown is an overall block diagram of an oxygenator with a negative pressure regulation function. The oxygenator 10 of this invention is composed of three devices: a pressure regulation device 100 , a gas exchange device 200 and a liquid volume measurement device 300 . Wherein, the liquid quantity measuring device 300 is installed inside the gas exchange device 200 , and the pressure regulating device 100 is installed on the shell of the oxygenation chamber 204 . The outside of the pressure regulating device 100 can be connected to the central negative pressure source 12 , and the inside is in communication with the gas exchange device 200 . The pressure regulating device 100 can adjust and control the internal pressure of the oxygenation chamber 204 through an external central negative pressure source 12, the ...

Abstract

The invention discloses an oxygenator with a negative pressure regulation and control function and a control method of the oxygenator with the negative pressure regulation and control function. The oxygenator comprises a pressure regulation and control device, a gas exchange device and a liquid volume measuring device; the gas exchange device is provided with an oxygenation chamber; the liquid volume measuring device is placed in the gas exchange device to measure liquid in the oxygenation chamber; the pressure regulation and control device is arranged on the oxygenation chamber, the outer portion of the pressure regulation and control device is connected with a central negative pressure source, the inner portion of the pressure regulation and control device communicates with the gas exchange device, and the pressure regulation and control device is used for regulating and controlling internal pressure of the oxygenation chamber; and the gas exchange device conducts gas exchange and heat exchange on blood which flows into the oxygenation chamber, and discharges the blood which flows into the oxygenation chamber. According to the oxygenator with the negative pressure regulation andcontrol function and the control method of the oxygenator with the negative pressure regulation and control function, the internal pressure of the oxygenation chamber is regulated and controlled through the pressure regulation and control device according to the requirements, a negative-pressure-assisted drainage effect is achieved, the gas exchange device conducts gas exchange and heat exchange on the blood which flows into the oxygenation chamber, and discharges the blood which flows into the oxygenation chamber, an oxygenation process regulated and controlled by negative pressure is achieved, and the drainage volume of venous blood is increased.

Description

technical field [0001] The invention relates to the technical field of medical device products, in particular to designing an oxygenator with a negative pressure regulation function and a control method thereof. Background technique [0002] The oxygenator quickly oxygenates the venous blood drawn from the body into arterial blood outside the body, and pumps it back into the body through an extracorporeal circulation machine to maintain the activities of various organs throughout the body. Therefore, the quality of the oxygenator directly affects the effect of extracorporeal circulation support, and the membrane oxygenator is the most commonly used due to its excellent performance. [0003] Conventional oxygenators venous blood is drained by gravity into the return chamber of the membrane lung. Air embolisms, tissue fragments and other microemboli are removed through a filter. The blood pump injects the blood from the recirculation chamber into the variable temperature cha...
