[0002] Infectious diseases are a class of diseases caused by various pathogens that can be transmitted between humans, between animals, or between humans and animals. A pathogenic sample collection device is a tool for safely and effectively collecting potential pathogens from patients or the environment. After collecting the pathogenic samples, they are analyzed and isolated to ensure thorough treatment. Therefore, the collection of pathogenic samples for infectious diseases is crucial for disease prevention.

[0003] Clinically, samples are generally collected through sampling tubes. Since the samples are infectious, it is not convenient to disinfect and sterilize the used sampling tubes, resulting in the sampling tubes being prone to secondary infection, seriously affecting the safety of users, and also affecting the accuracy of the test. There are also disposable sampling tubes used directly, and the sampling tubes are scrapped directly after use, increasing the use cost. Content of the Utility Model

A plurality of through holes communicating up and down are opened on the bottom plate. A threaded sleeve is detachably installed at the bottom of the outer tube. A collection tube is arranged inside the threaded sleeve. A sampling tube is installed at the lower end of the collection tube. A control component for controlling the communication state between the outer tube and the collection tube is arranged inside the collection tube. A negative pressure component for providing negative pressure to the sampling tube is arranged inside the outer tube.

[0006] Further, the negative pressure component includes a movable tube arranged vertically inside the outer tube. A tension spring is arranged between the lower end of the movable tube and the bottom plate. In the natural state of the tension spring, the movable tube is located inside the outer tube.

[0007] Further, a limiting groove is opened upward at the lower end of the movable tube. A sliding rod is vertically and independently inserted into the limiting groove. The lower end of the sliding rod is fixed on the bottom plate. The tension spring is sleeved outside the sliding rod.

[0008] Further, the control component includes a rotating plate. A sliding groove is opened on the inner side wall of the threaded sleeve. The rotating plate is horizontally arranged in the sliding groove. A plurality of through holes communicating with the through holes on the bottom plate are opened on the rotating plate. The upper end of the collection tube is fixed on the rotating plate.

[0009] Further, an external thread is arranged at the lower end of the outer tube. The threaded sleeve is sleeved on the lower end of the outer tube and is in threaded fit with it.

[0010] Further, a storage box is arranged below the sampling tube, a sealing paper is horizontally arranged at the inlet of the storage box, and a puncture needle is installed in the sampling tube through a connecting rod.

[0011] Further, the collection tube has a funnel-shaped structure with a larger upper part and a smaller lower part, and the collection tube is made of a transparent material.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, under the action of the control component, the outer tube is communicated with the collection tube, and under the action of the negative pressure component, the sampling tube samples the sample. After sampling, the outer tube and the collection tube are sealed, the outer tube is rotated, and the sample is stored in the collection tube.
