Problems solved by technology

[0002] When the liver is perfused, the mixed gas needs to be fed into the membrane oxygenator through the gas delivery system. The existing gas delivery system mixes oxygen, compressed air or other mixed gases through the air-oxygen mixer assembly in a certain fixed ratio and then enters the In the membrane oxygenator, moreover, the existing air-oxygen mixer generally adjusts the ratio of oxygen etc. manually, so the gas delivery volume of the hepatic artery and portal vein cannot be adjusted in real time according to the changes of the physiological parameters of the perfusate during liver perfusion. Moreover, the existing gas delivery system is generally fixedly installed in the surgical site, and cannot be moved and installed according to the surgical site.

Abstract

The invention discloses a gas delivery system for liver perfusion, the control module of which controls the work of the oxygen delivery control component and the compressed air delivery control component respectively according to the output results of the hepatic artery neural network training model and the portal vein neural network training model, so that the Based on the neural network training model and the preset oxygen partial pressure, carbon dioxide partial pressure and blood oxygen saturation, the real-time detection results of the hepatic artery detection module and portal vein detection module are trained respectively, and the gas in the hepatic artery and portal vein can be adjusted in real time and accurately delivery volume, so that the oxygen partial pressure, carbon dioxide partial pressure and blood oxygen saturation can be output stably according to the predetermined value; moreover, the bottom of the base is also equipped with universal wheels, so that the gas delivery system can be used and installed in different surgical sites ; In addition, when the gas storage capacity in the oxygen storage cylinder and the compressed air storage cylinder reaches a critical value, the relevant information can be notified to the operator in time through the alarm module.

Description

technical field [0001] The invention relates to the technical field of liver perfusion, in particular to a gas control device for liver perfusion. Background technique [0002] When the liver is perfused, the mixed gas needs to be fed into the membrane oxygenator through the gas delivery system. The existing gas delivery system mixes oxygen, compressed air or other mixed gases through the air-oxygen mixer assembly in a certain fixed ratio and then enters the In the membrane oxygenator, moreover, the existing air-oxygen mixer generally adjusts the ratio of oxygen etc. manually, so the gas delivery volume of the hepatic artery and portal vein cannot be adjusted in real time according to the changes of the physiological parameters of the perfusate during liver perfusion. Moreover, the existing gas delivery system is generally fixedly installed in the operation site, and cannot be moved and installed according to the operation site.
