The present application provides a kind of water conservancy nondestructive test membrane machine of heap body, it is related to heap body detection technical field.The membrane machine includes control mechanism, executing mechanism and drilling assembly, control mechanism includes drilling rig assembly and pump water component, drilling rig assembly includes rack, drilling rig and slide rail;Executing mechanism includes electric contact pressure gauge, feed power head and valve assembly, drilling assembly includes drill rod and membrane probe drill bit, one end of drill rod is connected with the water outlet of pump water mechanism through water pipe communication, one end of drill rod is connected with feed power head, membrane probe drill bit is set to the other end of drill rod, and high-pressure water flow is made through water pipe by mud pump, and finally high-pressure jet is carried out by membrane probe drill bit and is expanded, and drill rod is automatically followed.When membrane probe drill bit touches waterproof membrane, water flow passage on membrane probe drill bit is blocked, and the water pressure in water pipe is increased, and this pressure signal is transmitted to drilling rig by electric contact pressure gauge, and drilling rig controls drill rod to automatically stop following, and the position of underground waterproof membrane is accurately determined.

This invention relates to a p-Tau262 detection kit and its applications, particularly suitable for the accurate diagnosis of early Alzheimer's disease. The p-Tau262 detection kit comprises: a first antibody, which is a p-Tau262-specific antibody; and a detection reagent, which includes a second antibody or a lipid probe that specifically recognizes exosome membrane structures. The second antibody recognizes different p-Tau262 antigenic epitopes from the first antibody. By employing a combination of p-Tau262-specific antibodies recognizing different epitopes, or in combination with exosome membrane probes, this invention achieves high-sensitivity, high-throughput detection of the target, addressing the industry pain point of insufficient specificity of existing blood biomarkers in comorbid populations.
