Embodiment 1

[0031] see Figure 1 to Figure 6, a biological sample processing box, comprising a box shell 1, a constant humidity airflow generating device 2, a biological sample processing cavity 3, a control center 7 and a human-computer interface system 12, and the constant humidity airflow generating device 2 includes an airflow generator 21 , airflow humidity controller and airflow humidity monitoring device 29, the airflow humidity monitoring device 29 is installed at the outlet 20 of the constant humidity airflow of the constant humidity airflow generating device 2, the signal output end of the airflow humidity monitoring device 29 and the control center 7 signal input The terminal is connected, and the control command signal output end of the control center 7 is respectively connected with the command signal receiving end of the airflow generator 21 and the airflow humidity controller, so that the airflow humidity and the flow velocity derived from the airflow outlet 20 of the consta...

Embodiment 2

[0039] This embodiment is basically the same as the technical solution of the first embodiment, the difference is:

[0040] see Figure 4 , the exhaust gas discharged from the biological sample processing chamber 3 is filtered through the air filter device 43 to remove harmful gas components generated in the biological sample processing process. In the process of sample processing, the organic solvent used to fix biological samples flows out of the box with the flow of the airflow, causing pollution to the environment and affecting the health of operators. A waste gas filter device is installed at the outlet of the airflow, which can filter the production samples. The harmful gas generated during the treatment process is filtered to eliminate the harm to the health of the operator. In this embodiment, the above-mentioned air filter device 43 is filled with any one adsorbent or a mixture of several adsorbents among soda lime, calcium lime, soda lime and activated carbon. The a...

Abstract

The invention discloses a biological sample processing box, which comprises a box body shell, a constant-humidity airflow generating device, a biological sample processing cavity body, a control center and a human-machine interactive interface system. The constant-humidity airflow generating device comprises an airflow generator, an airflow humidity controller and an airflow humidity monitoring device, so the humidity and the flow rate of airflow which is led out from an airflow leading-out port of the constant-humidity airflow generating device can reach a system preset value, the biological sample processing cavity body is communicated with the constant humidity airflow generating device, the biological sample processing cavity body at least comprises one independent air cavity chamber unit, a movable drawer is arranged inside each air cavity chamber unit, a set of air temperature controllers is arranged inside each movable drawer, and the airflow which flows by the drawer is heated to a system preset temperature. Due to the adoption of the biological sample processing box, an environment with stable temperature and stable humidity can be provided, so the control precision of the humidity, the temperature and the airflow speed parameters can be greatly improved, the system working response time is short, convenience in installation and use can be realized, and the design and manufacturing cost is low.

Description

technical field [0001] The invention relates to a biological sample processing device, in particular to a biological sample processing device with constant and controllable internal temperature, humidity and air velocity. Background technique [0002] According to classical cytogenetics, chromosomes prepared from cells can be analyzed under a microscope to diagnose possible defects. Chromosome preparation requires the harvested cells to be treated with hypotonicity, fixation, drying, aging, enzyme digestion, and banding. After these treatments, the chromosomes of the cells can be analyzed under a microscope to determine whether there are chromosomal abnormalities. This classic method has been used since its inception. [0003] In the past few decades, major breakthroughs have been made in many aspects of cytogenetics technology, such as cell synchronization culture technology, high-resolution chromosome technology and in situ amniotic fluid cell chromosome analysis technolo...
