Oxyhemoglobin saturation control system in VV-ECMO mode and equipment

Abstract

The invention provides an oxyhemoglobin saturation control system in a VV-ECMO mode and equipment. The oxyhemoglobin saturation control system involves the ECMO equipment and at least one oxyhemoglobin detection device; and the ECMO equipment obtains a real oxyhemoglobin saturation value according to the received oxyhemoglobin saturation value collected by the oxyhemoglobin detection device and the detection values at an inlet and an outlet of the ECMO equipment, and performs increase and decrease control on oxyhemoglobin amount according to the real oxyhemoglobin saturation value. According to the system and the equipment, the problem that the data extraction accuracy is influenced by the human body cyclic oxygenation state in the VV-ECMO mode is solved, and a theoretical basis is furtherprovided for optimization of ECMO and the human body intubation position according to the internal relation rule among the ECMO inlet oxygenation data, the ECMO outlet oxygenation data and the humanbody cyclic 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...

AI Technical Summary

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
