Analysis of the Usage Problems of Fully Automatic Biological Tissue Dehydration Machine

With the rapid development of medical technology, tissue dehydrators have become one of the necessary large-scale instruments in daily tissue processing work in every large and medium-sized hospital. According to the design principles, tissue dehydrators can be divided into two types: rotary and fully automatic. Both types of tissue dehydrators may encounter common malfunctions during operation. Today, let's take a look at the common problems in the use of fully automatic biological tissue dehydrators.

KH-TK Biological Tissue Intelligent Dehydrator

Firstly, due to its high level of intelligence, low volatilization of reagents, large volume of processed tissue samples, and multiple selection functions during the dehydration process, such as how to pressurize, zero empty, and heat up, the common faults of the fully automatic tissue dehydrator are relatively complex, generally including the following:

1. When using pipeline to pump out reagents, if there are too many impurities mixed in the reagents, the pipeline will be blocked during the pump out of the reagents;

2. Insufficient vacuum pressure or pressure during reagent extraction, unable to continue normal dehydration;

3. Touch screen black or blue.

The corresponding maintenance methods are as follows:

1. Keep the cleaning solution clean, so that the dehydration tank can be cleaned clean and will not bring paraffin containing impurities into the pipeline and reagent bottle;

2. Perhaps one or several valves in the control gas circuit have malfunctioned, usually due to foreign objects inside the valve, which prevents the valve from working properly. The solution is to open the valve for cleaning;

3. There are many reasons for the black or blue screen on the touch screen. The repair plan is to shut down for a while and then restart to observe. If the work interface still cannot be opened, a new hard drive needs to be replaced.
