Multifunctional sample adding device for inspection equipment

Abstract

The invention relates to a multifunctional sample adding device for inspection equipment. The device comprises a mechanical arm, the mechanical arm is flexibly connected with a connecting rod piece, the two ends of the connecting rod piece are fixedly connected with a vibration source and a sample adding needle respectively, the vibration source drives the sample adding needle to vibrate, the connecting rod piece is provided with a sample adding channel, the sample adding channel is communicated with a sample adding needle and a sample adding pipe, and the sample adding pipe is a hose. The device further comprises a sleeve, the connecting rod piece is sleeved with the sleeve, the sleeve is connected with the mechanical arm, and the connecting rod piece is flexibly connected with the sleeve. According to the multifunctional sample adding device for inspection equipment, provided by the technical scheme, on the basis of an existing sample adding device, the vibration source is additionally arranged, the vibration source works to drive the sample adding needle to vibrate, and therefore the sample adding needle has the vibration function.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, and in particular relates to a multifunctional sample adding device used in testing equipment. Background technique [0002] Fully automatic biochemical / immune analyzers have been widely used due to their advantages of fast measurement speed, high accuracy, and small consumption of reagents. [0003] In the existing automatic biochemical / immune analyzer, the sample addition is completed by the sample addition arm, the stirring is completed by the stirring arm or the mixer, and the surface liquid removal after the sample injection needle is cleaned is completed by the negative pressure system. The functions of the three are separated. , making the structure of the automatic biochemical / immunity analyzer complex, which is not conducive to improving the operating efficiency and detection accuracy, and is also not conducive to reducing the manufacturing cost of the instrument. [0004] The...
