Abstract

The invention relates to a highly toxic medium sampling method and a highly toxic medium sampling device, solving the problem of the existing sample device in sampling of a highly toxic medium that the physical and mental health of operators can be harmed. The highly toxic medium sampling device comprises a sample chamber, wherein the sampling chamber is connected with a reactor through a first two-way valve, the outflow port of the sampling chamber is connected with a first connector of a four-way connector through a second two-way valve, a second connector of the four-way connector is connected with detoxification solution through a third two-way valve, a third connector of the four-way connector is connected with a cleaning device through a fourth two-way valve, a fourth connector of the four-way connector is connected with a tee valve, and the tee valve is provided with a first position communicated with a sampling bottle and a second position communicated with a fifth two-way valve. The invention also provides the highly toxic medium sampling method. The invention has the beneficial effects that the highly toxic medium can be sampled when the tee valve is in the first position, the residual medium in the device can be detoxified and cleaned when the tee valve is in the second position, and operators can be prevented from being injured by the medium when filling and taking the sampling bottle.

Description

technical field [0001] The present invention relates to a highly toxic medium sampling method and its device. Background technique [0002] In the production process of liquid products, in order to control the corresponding process parameters, it is often necessary to sample and analyze the liquid products in the container. Generally, a very simple combination of sampling valve and sampling tube is used to sample the product, but it is not competent for the sampling of samples such as tumor fluid, hormones, blood products, and biochemical media. When the ordinary sampling valve is used for the sampling of such media, since there is no detoxification process, the media in the valve body will cause great harm to the operator's body and mind. Therefore, it is urgent to develop a sampling valve or sampling device for highly toxic media. Protect the physical and mental health of pharmaceutical plant operators. SUMMARY OF THE INVENTION [0003] In order to solve the problem of...
