Abstract

The invention discloses a double-section sampling arm. The double-section sampling arm comprises a bracket assembly, a linear guide rail assembly, a rotary shaft assembly, an arm assembly and a needle assembly, wherein the linear guide rail assembly and the rotary shaft assembly are fixed on the bracket assembly; the linear guide rail assembly is connected with the rotary shaft assembly; the bracket assembly drives the arm assembly to move up and down by the rotary shaft assembly and the linear guide rail assembly; the arm assembly comprises a long arm which is rotatably connected on the rotary shaft assembly and a short arm which is used for connecting the needle assembly; and the short arm is rotatably connected on the end part of the long arm. The double-section sampling arm disclosed by the invention can sample within a range covered by the whole arm assembly under the condition of saving the space, simplifies the structure, shortens the stroke of the needle assembly and improves sampling efficiency.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic equipment, in particular to a double-section sample loading arm. Background technique [0002] In the prior art, there are two common types of sample loading arms for in vitro diagnostic equipment: the first is a sample loading arm that moves in a circular motion and up and down, but this sample loading arm can only take samples and reagents on the circumference; The second is a sample loading arm that moves in the X, Y, and Z three-dimensional directions. This sample loading arm can take samples and reagents at any position in a rectangular area. These two kinds of sample loading arms all have deficiencies: although the first sample loading arm is small in size and simple in structure, it can only take samples on the circumference, so the sampling area is too small; although the second sample loading arm has a wide sampling range, it cannot The volume is large, the structure is complex, error-...
