Full-automatic stirring sample feeding device with anti-collision function

Abstract

The invention relates to a full-automatic stirring sample feeding device with an anti-collision function. The full-automatic stirring sample feeding device with the anti-collision function comprises asample adding needle, a to-be-tested sample assembly and a liquid substance testing device, and the liquid substance testing stirring device is composed of a stirring bar rotating mechanism, a stirring bar lifting mechanism and a stirring bar anti-collision alarming mechanism; the liquid substance testing stirring device is arranged on the upper plane of the to-be-tested sample assembly in an overhead mode, and the to-be-tested sample assembly is a to-be-tested sample assembly group capable of displacing along the XY plane; the sampling adding needle achieves sampling of to-be-tested liquid through a hollow stirring bar in the stirring bar rotating mechanism and the stirring bar lifting mechanism, and meanwhile, can achieve that the stirring bar rotates and mix uniformly in a liquid containing test tube of the to-be-tested sample assembly and lifts up and down in the Z direction under driving of the stirring bar rotating mechanism and the stirring bar lifting mechanism; additionally,the stirring bar can achieve the automatic anti-collision alarming function under the transmission effect of the stirring bar anti-collision alarming mechanism.

Description

technical field [0001] The invention relates to a medical liquid object detection auxiliary device, in particular to a full-automatic stirring and sampling device with an anti-collision function, which is suitable for in vitro diagnostic medical devices for testing human blood, urine and other samples. Background technique [0002] In clinical medicine, some in vitro diagnostic equipment mainly realizes the detection of blood, urine and other samples of patients, and provides the obtained detection results to clinicians for analysis of patients. However, most tests (such as blood cell tests) need to mix the samples before the test to achieve accurate test results. At the same time, there is an increasing demand for fully automatic medical testing instruments in the market to ensure the accuracy of test results and greatly improve the detection efficiency. [0003] At present, the way to achieve sample stirring in the market is mainly to use two sets of independent structure...

AI Technical Summary

Problems solved by technology

[0003] At present, the way to achieve sample stirring in the market is mainly to use two sets of independent structures to independently and sequentially complete the sample stirring and sampling work. Therefore, the inspection period for a single sample is long, and it is not suitable for how to further improve the detection. The timeliness of analysis and making it more quickly and effectively adapt to the needs of clinical medicine have become issues that medical equipment manufacturers should consider
