Puncture liquid adding and mixing machine

Abstract

The invention discloses a puncture liquid adding and mixing machine, and the machine is used for automatic puncture liquid adding dilution and puncture uniform mixing stirring of a specimen, and comprises a base plate, a test tube rack and a specimen collection cup, wherein the specimen collection cup is sleeved and positioned in the test tube rack; a cantilever support is arranged above the specimen collection cup in the test tube rack, and a liquid adding needle and a stirring mechanism which are simultaneously inserted into the specimen collection cup in a puncturing manner for adding liquid and diluting respectively are arranged on the cantilever support opposite to a tube opening of the specimen collection cup; a uniform mixing needle is arranged on the stirring mechanism, a collection spoon nested and matched with the bottom end of the uniform mixing needle inserted by the puncture is arranged in the corresponding specimen collection cup, and the uniform mixing needle drives thecollection spoon to uniformly mix and stir a specimen diluted by adding liquid into the specimen collection cup; a linear lifting mechanism for driving the cantilever frame, the liquid adding needle connected with the cantilever frame and the stirring mechanism to synchronously lift up and down is mounted on the base plate; automatic puncture liquid adding dilution and uniform mixing separation are carried out in a full-closed state, cross contamination and operator infection are effectively avoided, pollution is avoided, and the working efficiency is high.

Description

【Technical field】 [0001] The invention relates to medical device technology, in particular to a puncture adding liquid mixer. 【Background technique】 [0002] In modern life, various diseases keep appearing, and the collected specimens need to be mixed in medical examination, but there are many samples that need to be mixed, the efficiency of manual operation is low, there are safety hazards and the mixing is uneven. At present, there are two types of automatic mixing of collected specimens: shaking method and rotating method. In medical equipment, the specimen mixing method used is mostly clamping mixing method. The specific operation method is: put the test tube with an elastic The clip is clamped and rotated, and then other devices are used to puncture and sample it, and the functions of puncture and mixing are realized by two different mechanisms. Generally, the mixing mechanism needs at least two parts, the holder support and the holder, which are installed on the motor...

Problems solved by technology

[0004] At present, the mixers for mixing stool samples have the characteristics of long mixing time, insufficient uniformity and sufficient mixing, and cell damage is likely to be caused during the mixing process, which leads to large errors in the detected data and leads to inaccurate testing of the samples. If the actual result is not obtained, the final test result will be inaccurate, resulting in misjudgment by the doctor; moreover, it is easy to cause the specimen to leak during the test process, which will emit peculiar smell and cause office environment pollution, which is neither safe nor hygienic At the same time, the existing stool specimen mixer is not highly automated and requires manual sampling, which is prone to operational errors, low work efficiency, and time-consuming and laborious
