A blood oxygen saturation control system and equipment in vv-ecmo mode

Abstract

The present disclosure provides a blood oxygen saturation control system and equipment in VV-ECMO mode, including ECMO equipment and at least one blood oxygen detection device; the ECMO equipment receives blood oxygen saturation values ​​collected by the blood oxygen detection device And the detection value of the entrance and exit of the ECMO equipment, get the real blood oxygen saturation value, and control the increase or decrease of the blood oxygen amount according to the real blood oxygen saturation value; The problem of data extraction accuracy provides a theoretical basis for the optimization of ECMO and human intubation positions based on the internal relationship between ECMO inlet and outlet oxygenation data and human body circulation oxygenation data.

Description

technical field [0001] The present disclosure relates to the technical field of extracorporeal membrane oxygenation, in particular to a blood oxygen saturation control system and equipment in VV-ECMO mode. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] ECMO (extracorporeal membrane oxygenation), extracorporeal membrane oxygenation, referred to as membrane lung, also known as "mobile cardiopulmonary instrument", is to drain blood from the human body, oxygenate it outside the body and then return it to the body to replace Equipment for normal heart and lung function. For patients with lung failure, ECMO can replace the normal lung and heart functions, allowing the patient's lungs or heart to fully rest, allowing time for treatment and recovery. After the lungs or heart recover well, ECMO can be weaned off. In view of its unique curative...

Problems solved by technology

[0005] The inventors of the present disclosure found that the existing ECMO detects blood oxygen saturation at the outlet and inlet of the artificial heart pump, which is different from the actual blood oxygen saturation of the human body, requiring doctors to perform traumatic operations (arterial blood gas analysis) Repeatedly delaying the operation of ECMO according to the results increases the workload of the nursing staff, and due to the differences between each nursing staff, the effect of manual intervention adjustment is also different; The blood at the inlet and outlet of the device is monitored without contact, and the monitoring result is updated every 12 seconds, which is real-time monitoring. The monitoring result does not represent the blood oxygen content after the ECMO reinfusion blood flow is mixed with the blood pumped by the heart, and the blood Oxygen levels are a key indicator for supplying vital organs such as the brain, leading to inaccurate movements of ECMO devices
