Multi-functional in-vitro life support and treatment system integrated device

Abstract

The invention discloses a multi-functional in-vitro life support and treatment system integrated device. The device comprises a centrifugal pump, an extracorporeal membrane oxygenation device, a plasma separator, a blood filtration column and a bilirubin adsorption column. The device can enable simultaneous clinical support and treatment of multiple organ functions to be possible by integrating the support and the treatment of the multiple organ functions into a whole; the device is simple to operate and convenient to carry, and can provide possibility for the support and the treatment of the multiple organ function of an out-of-hospital critically ill patient and provide a safe and effective measure for the out-of-hospital patient; the device can avoid multiple arterial / venous catheterization, various complications caused by the multiple catheterization and reduce the side effects of the support and the treatment of the multiple organ functions to the greatest extent; and the device is strong in compatibility and becomes a system which can be compatible with cardiopulmonary support, renal replacement therapy, liver function support, artificial enteral nutrition, immunoregulation and treatment and other various support and treatment means.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a multifunctional extracorporeal life support and treatment system integration device. Background technique [0002] In the past 20 years, extracorporeal organ function replacement (or support) therapy has developed rapidly, which has significantly improved the success rate of some critically ill patients. For organs that are dysfunctional or even damaged and lose their function, extracorporeal support or replacement therapy is used. This kind of extracorporeal organ function support or replacement therapy not only buys precious time for the treatment of the seriously ill, but also reduces the burden on the damaged organs, allowing them to fully "rest", which is conducive to the recovery of their functions, thereby Improve the success rate of rescue. However, there are still many deficiencies and limitations in these supportive treatments, especially technical deficiencies, which s...

Problems solved by technology

However, due to the incompatibility of biomaterials, hemodynamics, tubing connections, intubation sites, etc., these extracorporeal support systems can only function independently, and can only be placed separately when multiple organ function support is required. Tubes, independent connecting lines, independent circulation, etc., which not only significantly increase the treatment cost of patients, but also cumbersome operation, increase the risk of repeated catheterization and various complications, such as aggravating stress, increasing the risk of thrombosis, The ischemia and necrosis of the extremities caused by the blood vessel supply area at the tube site and the blood return disorder increase the risk of immune disorder and even death, which severely limits the clinical application of multiple organ function support at the same time.

[0005] 3. The current life support means only have a limited role of "support", but cannot achieve the role of treatment. In critically ill patients, the imbalance of immune and inflammatory responses is one of the important factors leading to the death of critically ill patients

[0006] 4. In addition, the current supportive treatment equipment for various organs outside the body is large in size and complicated to operate. So far, it is only used for hospital treatment. etc., resulting in a sharp increase in various types of severe trauma patients, there is an urgent need for the emergence of a multifunctional extracorporeal life support system that is easy to carry, flexible to use, and in and out of the hospital.
