Embodiment 1

[0031] see Figure 1 to Figure 6, a biological sample processing box, including a box shell 1, a constant humidity airflow generating device 2, a biological sample processing chamber 3, a control center 7 and a human-computer interaction 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 terminal of the airflow humidity monitoring device 29 and the control center 7 signal inputs The control command signal output terminal of the control center 7 is connected with the command signal receiving end of the airflow generator 21 and the airflow humidity controller respectively, so that the airflow humidity and flow velocity derived from the airflow outlet 20 of the constant humidity ...

Embodiment 2

[0039] The technical solution of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[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 during the biological sample processing process. During sample processing, the organic solvent used to fix biological samples flows out of the box with the flow of airflow, polluting the environment and affecting the health of operators. A waste gas filter device is installed at the outlet of the airflow, which can remove the production samples Harmful gases generated during the treatment process are filtered to eliminate health hazards to operators. In this embodiment, the above-mentioned air filter device 43 is filled with any adsorbent or a mixture of several adsorbents in soda lime, calcium lime, soda lime, and activated carbon. The adsorbent is low in cost and easy to ...

Abstract

The invention discloses a biological sample processing box, which comprises a box shell, a constant humidity air flow generating device, a biological sample processing cavity, a control center and a human-computer interaction interface system. The constant humidity airflow generating device includes an airflow generator, an airflow humidity controller and an airflow humidity monitoring device, so that the humidity and flow rate of the airflow derived from the airflow outlet of the constant humidity airflow generating device reach the system preset value, and the biological sample processing chamber and the constant humidity The airflow generating device is connected, and the biological sample processing chamber includes at least one independent gas chamber unit. Each gas chamber unit has a built-in movable drawer, and a set of airflow temperature controller is installed inside each movable drawer, which will flow through the drawer. The airflow is heated to the system preset temperature. The invention can provide a stable temperature and humidity environment, greatly improve the control accuracy of the parameters of humidity, temperature and air velocity, has short system response time, is easy to install and use, and has low design and manufacturing costs.

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...
