Diabetic foot wound exudate detection chip

Abstract

The invention belongs to the technical field of micro-fluidic chips, and discloses a diabetic foot wound exudate detection chip. The detection chip comprises a substrate, a detection pad is arranged on the substrate, and a sample adding area, a channel area, a reaction area and a water absorption area are arranged on the detection pad; the channel area comprises a non-acceleration channel, the inlet end of the non-acceleration channel is communicated with the sample adding area, the outlet end of the non-acceleration channel is communicated with the reaction area, a color developing agent coating area is arranged on the non-acceleration channel, and acceleration channels are arranged on the two sides of the non-acceleration channel; a drainage interval is arranged between the non-acceleration channel and the acceleration channels; the inlet ends of the acceleration channels are communicated with the sample adding area, an inclined channel is arranged at the outlet end of each acceleration channel, the acceleration channels are communicated with the reaction area through the inclined channels, and an antibody coating area is arranged on each acceleration channel; a detection line and a quality control line are arranged in the reaction area, and the outlet end of the reaction area is communicated with the water absorption area. The detection chip can rapidly detect whether wound exudate of a diabetic foot patient contains MMP-9 or not, the recovery condition of the wound of the patient can be known in time, and help is provided for follow-up treatment.

Description

technical field [0001] The invention relates to the technical field of microfluidic chip detection, in particular to a diabetic foot wound exudate detection chip. Background technique [0002] Microfluidic chips have attracted much attention because they can integrate detection items in traditional laboratories on a tiny chip, and have been widely used in biomedicine, environmental and food testing and other fields. [0003] On-site rapid detection (Point of Care Test, POCT) is an important field of in vitro diagnosis; it makes patients no longer need to go to the hospital to undergo complicated and time-consuming biochemical examinations, and only needs a miniaturized device to obtain the desired results . At present, the blood glucose meter is the most successful POCT device; patients can check their blood sugar status anytime and anywhere, and no longer need to go to the hospital for testing. [0004] As a branch of microfluidic chip, microfluidic paper analysis equipme...
