Description

Exempt from to uncap new hat sample preservation pipe

Technical Field

The utility model relates to the technical field of clinical medical examination, in particular to a novel crown sample storage tube without opening a cover.

Background

A nucleic acid detection method is commonly used for detecting whether a patient has new coronary pneumonia, and the nucleic acid detection substance is nucleic acid of virus. The nucleic acid detection is to find out whether the nucleic acid of the foreign invader virus exists in the respiratory tract specimen, blood or feces of the patient to determine whether the patient is infected by the new coronavirus. Once a nucleic acid is detected as "positive", the presence of the virus in the patient is verified. After the new coronavirus infects human body, it will propagate in respiratory tract system, so it can judge whether human body is infected by virus by detecting virus nucleic acid in sputum and nasopharyngeal swab.

Chinese patent with application number CN202020771191.2 discloses a storage tube for sampling swab, including a tube body, be equipped with the second cavity that is used for storing the first cavity of sample release agent and is used for placing the sampling swab in the body, first cavity and second cavity intercommunication set up, the central axis of second cavity deviate from in the central axis of body. When the device is used, the sampling swab is placed in the second cavity, moves up and down in the second cavity and is eluted in a rotating mode, the nucleic acid sample of the sampling swab is uniformly distributed in the sample releasing agent, and the sample releasing agent in the first cavity is sucked for detection; the utility model omits the process of extracting the nucleic acid sample by oscillating elution, and the swab is vertically arranged in the second cavity which is arranged in a way of deviating from the center of the tube body, thereby providing an operation space for sampling operation, simplifying the operation process of nucleic acid detection and facilitating the operation of clinical tests.

When the storage tube stores the sample and then carries out nucleic acid detection, the new crown sample storage tube needs to be opened, and liquid in the tube needs to be sucked out for carrying out nucleic acid detection. Because the liquid is viscous after the sampling tube collects the throat swab, once the sample tube is turned upside down in the transportation process, the viscous liquid can be attached to the tube cover and the tube wall of the sample tube. When the sample collection tube enters a medical detection laboratory for detection, viscous liquid can be leaked out with high probability in the process of opening the sample tube, so that unnecessary pollution is caused. And in the large-scale sampling, the uncovering work consumes a large amount of time of workers and causes discomfort of the hands of the workers (the uncovering needs large force). Therefore, the uncapping work of the nucleic acid detection is time-consuming and labor-consuming, and the sample is easy to leak to cause pollution.
