according to the blood sampling assembly with the blood sampling needle integrated piece and the test strip integrated piece, the blood sampling needles and the blood sugar test strips can be arranged in the shell assembly at one time, when the blood sampling assembly is used, the blood sampling needles and the corresponding blood sugar test strips can be pushed out of the shell assembly in sequence to perform multiple blood sugar detection, the blood sampling needles and the blood sugar test strips do not need to be frequently replaced, the blood sampling assembly is very convenient to use, and in addition, because the blood sampling needles are arranged in the blood sampling assembly, a user cannot directly contact with the blood sampling needles, so that the risk of disease infection caused by the fact that the user is pricked by the blood sampling needles is reduced.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention.
