Portable ECMO system

Abstract

The invention discloses a portable ECMO system. The portable ECMO system is characterized in that a centrifugal pump is driven to work to enable blood output from a human organ to be first processed by an oxygenator and then transmitted back to the human organ through the centrifugal pump. The blood that meets the needs of life is provided for the human organ to maintain the life of a patient andachieve functions of assisting work of human heart and lung organs. The system can obtain data such as blood flow temperature, flow speed and pressure dynamically in real time through an external sensor group in the non-invasive contact mode, i.e. the invasive diagnosis mode, acquires indicators such as arteriovenous oxygen saturation, microthrombus and hemoglobin dynamically in real time and displays the information on a display screen for an operator to monitor the system operation and measure extracorporeal circulation physiological and pathological indicators in real time. The data can also be transmitted to other receiving devices through a wireless communication transmission module in the system for the operator to have a better understanding of the physical condition of a patient remotely.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable ECMO system. Background technique [0002] The ECMO system is used to process the blood in the extracorporeal blood circulation. It is a short-term assisting device for the heart and lungs. It is used to provide short-term assistance to the patient's heart through extracorporeal circulation, enabling the patient's blood to be oxygenated through the extracorporeal membrane lung. a technique. However, none of the existing ECMO systems can perform real-time dynamic monitoring of key indicators of blood, such as blood oxygen saturation, microemboli, and hemoglobin, without direct contact or non-invasiveness. The flow rate of the centrifugal pump, the key component, and the working efficiency of the oxygen generator (reflected by the transmembrane pressure difference) cannot be dynamically monitored in real time. Existing ECMO systems cannot freely switch between ...

Problems solved by technology

However, none of the existing ECMO systems can perform real-time dynamic monitoring of key indicators of blood, such as blood oxygen saturation, microemboli, and hemoglobin, without direct contact or non-invasiveness.

Dynamic real-time monitoring of the flow rate of the key components of the centrifugal pump and the working efficiency of the oxygen reactor (reflected by the transmembrane pressure difference) cannot be realized

Existing ECMO systems cannot freely switch between advective perfusion and pulsatile perfusion modes
