Abstract

The invention discloses a military micro-fluidic chip for detecting an infection marker and a detection method thereof. The military micro-fluidic chip comprises a connecting assembly, wherein the connecting assembly comprises an upper valve frame, the lower side of the upper valve frame is connected with a lower valve frame, the front end and the rear end of the upper valve frame are connected with the lower valve frame through a first short pin and a second short pin, an installation opening is formed between the upper valve frame and the lower valve frame, an upper connecting hole and a lower connecting hole which are coaxial are respectively formed in the upper valve frame and the lower valve frame, a micro-fluidic reaction assembly for detecting the infection marker is connected between the upper valve frame and the lower valve frame, and a control valve capable of moving in a height direction is connected to the micro-fluidic reaction assembly and the connecting assembly. Various solutions in the micro-fluidic reaction assembly are fed according to a detection sequence through the control valve. The military micro-fluidic chip is simple in structure, convenient to detect and short in detection time.

Description

technical field [0001] The invention relates to the technical field of detection of infection markers, in particular to a microfluidic chip for military use to detect infection markers and a detection method thereof. Background technique [0002] Point-of-care testing (POCT) can provide test results nearby and quickly, and provide guidance for diagnosis and treatment. Compared with traditional detection methods, POCT equipment has the characteristics of portability, easy operation, and rapid detection. For common diseases in the military, POCT equipment can provide a more convenient detection method, which can effectively guarantee the life, health and safety of soldiers in training grounds, battlefields and other complex militarized environments. [0003] Infection can range from minor skin trauma to severe organ failure, which is very common in military training, battlefield and other environments. Severe infection can lead to sepsis, and each hour of delay in sepsis tre...
