Problems solved by technology
[0003] The purpose of the present invention is to solve the problem that the storage tube in the prior art needs to be divided into multiple small samples for detection with the help of external extraction tools, resulting in an increase in the cost of the tool. When the storage tube is opened at the same time, there will be dust or bacteria infecting the test sample, which will affect the quality of the test sample. The shortcomings of the test results of the sample, and a liquid test sample storage tube proposed

The invention discloses a liquid detection sample storage tube which comprises a storage tube, a fixing block and a soft gas guide tube are spirally connected to the side wall of the upper end of the storage tube at intervals, an extrusion block is in extrusion contact with the soft gas guide tube, a valve device comprises a fixing plate, an inner cylinder and an outer cylinder, the fixing plate is fixedly connected to one end of the inner cylinder, and the outer cylinder is fixedly connected to the other end of the inner cylinder. A soft catheter is inserted into the inner cylinder and the catheter through hole in a penetrating mode, one end of the soft catheter is communicated with the lower end of the side wall of the storage tube, and the inner cylinder is sleeved with an outer cylinder in a threaded mode. Through spiral rotation of the outer cylinder in the valve device on the inner cylinder, the side wall of one end of the outer cylinder and the fixing plate are in extrusion contact with the soft liquid guide pipe, sealing of the soft liquid guide pipe is achieved, and primary sealing of the soft liquid guide pipe is also achieved; the second air bag and the first air bag are in contact with the soft catheter through extrusion, so that it is guaranteed that no dust enters the soft catheter, the soft catheter is not infected with bacteria, and then secondary sealing of the soft catheter is achieved.
Description
technical field [0001] The invention relates to the technical field of laboratory detection, in particular to a liquid detection sample storage tube. Background technique [0002] Liquid detection is a common detection type in the laboratory, but the liquid is stored in the storage tube during detection, and there are different forms of detection according to the test subjects, but the existing liquid storage tube needs to be extracted by liquid extraction tools Multiple small samples will increase the use of extraction tools and increase the economic cost of scientific research. At the same time, the extraction tools need to be cleaned from time to time, and some liquid detection storage tubes need to be opened to extract test samples. When the liquid storage tube is opened Yes, there will be dust or bacteria entering the storage tube, which will affect the test results of the liquid test sample. The existing liquid storage tube is not convenient for operators to use. In vi...
