Stool specimen automatic mixing device

Abstract

The invention discloses a stool specimen automatically mixing device, including a rotary table, a positioning plate, a positioning sleeve, a spindle, a stent, a stepping motor and a controller. The rotary table is connected with an output shaft of the stepping motor through the spindle. The positioning sleeve is connected with the positioning plate. And the positioning sleeve and the positioning plate are arranged on the spindle. The stepping motor is installed on the stent. A signal input end of the controller is connected with the positioning plate and an output end is connected with a control switch of the motor. The rotary table is vertically installed on one end of the spindle. The rotary table is equipped with grooves for carrying specimens. A specimen vessel filled with a stool sample to be tested is put on the groove with a relative label on the rotary table. The controller controls the stepping motor to rotate. And the stepping motor drives the rotary table to rotate. With thecentrifugal force caused by the variable speed rotation of the stepping motor and the effect of the self-gravitation of the specimen, the invention is continuously and repeatedly reversed to mix thespecimen and liquid in an acquisition apparatus. Therefore, the invention has the advantages of high test precision, even mixture, high efficiency, etc.

Description

Technical field The invention discloses an automatic mixing device for stool specimens, which belongs to the technical field of medical detection equipment. Background technique In modern life, various diseases continue to appear, and the collected specimens need to be mixed in medical testing. However, when there are many specimens to be mixed, manual operation efficiency is low, safety hazards and incomplete mixing are caused. Since stool samples have the characteristics of high specific gravity and strong aggregation, they are easy to settle naturally. Therefore, when measuring stool samples with medical measuring equipment, the stool samples must be fully mixed first to ensure the accuracy of the measurement results. At present, the mixed stool samples have the characteristics of longer mixing time, insufficient mixing, and sufficient cell damage during the mixing process, which leads to large measurement data errors and inaccurate final measurement results; shake the sampl...
