Problems solved by technology
[0003] First of all, in the traditional collection process, the pipette gun is required to collect different reagents, mix the reagents in a container, and then take out the mixed solution and put it into the analysis instrument for immunological analysis. The collection process requires multiple liquids to be collected one by one. As a result, the acquisition takes a long time, which limits the efficiency of fluorescent immunoassay. At the same time, because immunoassays need to use multiple supplies such as pipettes, buffer reagents, pipette tips, and mixing containers, outdoor, or In special scenarios, there are restrictions such as inconvenient portability and environmental requirements, and there are major design defects

The invention provides a portable injection device for sampling and sample adding, which comprises a shell, a suction mechanism and a guide part; the interior of the shell is hollow, and the top of the shell is open to form a first cavity; the suction mechanism is arranged in the first cavity; the guide part is used for guiding the reagent and is arranged at the bottom of the shell; wherein the suction mechanism comprises a drainage piece and a gland, a hollow part is arranged in the drainage piece, the gland comprises a piston rod which is in sliding connection with the drainage piece, the piston rod extends into the hollow part of the drainage piece, so that a closed liquid mixing cavity is formed in the piston rod, and the guide part is communicated with the liquid mixing cavity, so that the carrying convenience and the operation accuracy of a user are effectively improved; and the device is convenient to use and simple in structure.
Description
technical field [0001] The invention belongs to the field of medical instruments, in particular to a portable injection device for sampling and adding samples. Background technique [0002] In the field of medical devices, especially in fluorescent immunoassays, it is always known to use a pipette to mix various reagents into a mixture for analysis. However, the inventors have found that at least the following problems exist in the existing sampling process: [0003] First of all, in the traditional collection process, the pipette gun is required to collect different reagents, mix the reagents in a container, and then take out the mixed solution and put it into the analysis instrument for immunological analysis. The collection process requires multiple liquids to be collected one by one. As a result, the acquisition takes a long time, which limits the efficiency of fluorescent immunoassay. At the same time, because immunoassays need to use multiple supplies such as pipettes...
