Blood oxygenation device

Abstract

The invention discloses a blood oxygenation device which comprises a blood input pipeline, a blood output pipeline, an oxygenation branch, a blood purification branch, an oxygenator, a power part, a hemoperfusion device, a control system and a first timing part used for detecting the continuous working time of the power part. The oxygenator and the power part are arranged on the oxygenation branch in series, and the hemoperfusion device is arranged on the blood purification branch; the control system is configured to control the oxygenation branch to start working; feedback information of the first timing component is obtained; if it is judged that the continuous working time of the oxygenation branch is longer than or equal to the first preset time, a first control signal is sent out; the first control signal is used for indicating that the blood purification branch is connected to the oxygenation branch, so that the oxygenation branch and the blood purification branch work at the same time. Whether HP treatment is added or not is judged through the control system, medical staff do not need to judge when HP treatment is added according to experience, and application and popularization of an ECMO + HP treatment mode are facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a blood oxygenation device. Background technique [0002] Extracorporeal Membrane Oxygenation (ECMO) treatment technology is mainly used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure to maintain the life of the patient; among them, the basic principle of ECMO treatment is: from the blood to the human body Through the membrane lung oxygenation of the oxygenator, the carbon dioxide in the blood is removed, and the oxygenated blood is returned to the vein of the human body (V-V bypass), or returned to the artery of the human body (V-A bypass) ); Among them, ECMO treatment can be divided into: V-V shunt and V-A shunt, of which V-V shunt is mainly used for extracorporeal respiratory support, and V-A shunt can be used for both extracorporeal respiratory support and cardiac support. ECMO treatment technology has been wid...

Problems solved by technology

This combined treatment method needs to rely on artificial subjective judgment, and the medical staff can add HP treatment at any time according to their own experience. Forget to add HP treatment during ECMO treatment. On the other hand, medical staff lack standard operation methods, which can easily lead to incorrect time points for adding HP treatment during ECMO treatment, and inflammatory factors are cleared when patients undergo HP treatment. The effect is not good; inexperienced medical staff do not know how to perform HP and ECMO combined treatment operations, so they will not use HP+ECMO treatment, which is also the core problem that limits the popularization and application of HP+ECMO treatment; A new type of HP+ECMO treatment to solve this problem
