Inspection specimen pretreatment device and using method thereof

Abstract

The invention discloses an inspection specimen pretreatment device and a use method thereof, and belongs to the technical field of specimen pretreatment. According to the invention, ordered black space storage and timing can be carried out on a whole rack of specimen mixed liquid added with specimens and reagents in batches, and batch quantitative sample adding of the same reagent is realized, sothat liquid separation efficiency can be improved; a plurality of mixed solutions after liquid adding are subjected to auxiliary uniform mixing, so that the reaction efficiency of the mixed solution is greatly improved, and the accuracy of an inspection result is guaranteed; series operation in traditional manual operation is changed into mechanical parallel operation, so that the operation time is saved while the personal safety of workers is prevented from being endangered; the device not only can be suitable for flow cytology, but also can be used for adding the same kind of reagents in batches; and the specimens after sample adding can be stored in different places, personnel need to spend energy in different places to find the specimens for treatment, or the problem that the cost is additionally increased in a laboratory to build a darkroom is solved, and effective space in the laboratory can be utilized by using the whole device.

Description

technical field [0001] The present invention relates to the technical field of specimen pretreatment, and more specifically, to a test specimen pretreatment device and a method for using the same. Background technique [0002] Before flow cytometry specimen detection, the laboratory staff first add the specimen and the corresponding monoclonal antibody according to the preset items, shake it manually, and then place it in a dark space to fully combine the specimen and the antibody for a period of time (timing After the setting time of the timer), add a certain volume of hemolyzing agent one by one to the artificial single specimen, mix well again, and then fully hemolyze it again in a dark space, and place it for a period of time (timer setting time), and then carry out the follow-up Centrifuge, process and detect. Larger-scale laboratories use flow-type workstations with specimen processing devices, which are part of the workstations and have high efficiency, but the cost ...

AI Technical Summary

Problems solved by technology

Larger-scale laboratories use flow-type workstations with specimen processing devices, which are part of the workstations and have high efficiency, but the cost is too high, which limits their use in flow-type laboratories, making the flow-type laboratory specimen processing still in the manual stage

[0003] In recent years, flow cytometry has become more and more widely used in medical laboratories. Manual processing of flow cytometry specimens is time-consuming, laborious, and inefficient, which has become a major obstacle to the improvement of the efficiency of flow cytometry laboratories. Time-consuming means that after each darkroom is placed It can only be shaken well, and the number of specimen tubes that can be obtained manually each time is limited, so it needs to be divided into multiple times, and the addition of hemolytic agent can only be added one tube at a time, which affects the efficiency; When the specimen is shaken, it is necessary for personnel to hold the specimen tightly to prevent the specimen from falling and leaking, which will cause the specimen to fail to continue testing. Once the specimen falls, it will easily cause biological hazards to the staff and cause the specimen to fail to continue testing

On the other hand, the darkroom needs to be built separately, or placed in a dark space such as a drawer. Building another darkroom will increase the operating cost of the laboratory, increase the number of people walking back and forth, and affect efficiency. Storing bills in drawers can only solve the storage problem, but cannot solve efficiency problems
