Self-balancing replacement device for multiple organ support

Abstract

The invention discloses an automatic balancing displacement device used for supporting multiple organs. The automatic balancing displacement device is arranged on fluid infusion channels and ultrafiltrate channels; flow balance of the fluid infusion channels and the ultrafiltrate channels are maintained in a volume displacement mode. The automatic balancing displacement device comprises a first rigid cavity, a second rigid cavity, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve. The first rigid cavity is divided into a first left side cavity and a first right side cavity. The second rigid cavity is divided into a second left side cavity and a second right side cavity. The first electromagnetic valve is connected with the first left side cavity and the second left side cavity. The second electromagnetic valve is connected with the first left side cavity and the second left side cavity. The third electromagnetic valve is connected the first right side cavity and the second right side cavity. The fourth electromagnetic valve is connected with the first right side cavity and the second right side cavity. With the automatic balancing displacement device, the current problems that balancing cavity is big in volume, portability is poor, error signals are generated frequently in the environment of rocking motions, and a portable treatment instrument supporting multiple organs cannot be used in poor environments are solved.

Description

technical field [0001] The invention relates to blood purification and multi-organ function support technology, in particular to a self-balancing replacement device for multi-organ support. Background technique [0002] Wars, shipwrecks, earthquakes and various natural disasters caused a large number of injuries, and the injuries were extensive, complex and serious, and then rapidly progressed to multiple organ failure, resulting in a significant increase in mortality. In addition, it was far away from the hospital, so it could not be evacuated in time, and treatment must be carried out on the spot. Therefore, it is of great significance to provide early multi-organ function support treatment for these seriously injured patients in order to save lives. [0003] Multi-organ function support therapy includes: continuous blood purification for renal function replacement, artificial oxygenation (model lung) respiratory function support and artificial liver support system, etc. ...
