[0002] Medical testing is a science that tests materials taken from the human body in microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc., so as to provide information for the prevention, diagnosis, treatment of human diseases and the assessment of human health. In the process of testing, sampling tubes are indispensable for sampling samples;

[0003] After searching, the authorization announcement number CN218393742U discloses a splash-proof medical detection sampling tube, including: a sampling tube body, an accommodating cavity is opened inside the sampling tube body. When the above device is in use, although it can avoid the problem of sample leakage caused by accidental squeezing of the pull plate, it requires too much manual operation during use, which affects the sampling efficiency. At the same time, multiple structures increase product costs. Therefore, a splash-proof medical detection sampling tube is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a splash-proof medical testing sampling tube, which can seal the sample tube by rotating the sealing disk, and the operation is convenient and fast, while avoiding the splashing of samples caused by accidental contact with equipment.

[0007] A piston is slidably connected inside the sample storage tube, the guide rod passes through the piston, a sleeve is fixedly connected to one side of the piston, the sleeve is sleeved on the circumference of the guide rod and passes through the sample storage tube, a second guide plate is fixedly connected to the circumference of the guide rod, the second guide plate is slidably connected to the sleeve, and the sealing disk and the limiting disk are used in conjunction, so that after sampling of the sample storage tube is completed, the sample storage tube can be closed by rotating the sealing disk, the operation is convenient and fast, and splashing of the sample due to accidental contact with the equipment is avoided.

[0008] As a further solution of the utility model, the end of the sample storage tube away from the sampling head is fixedly connected to a plurality of guide blocks, a reset disk is rotatably connected between the plurality of guide blocks, the circumference of the sleeve is fixedly connected to a first guide plate, the first guide plate and the sleeve slide through the reset disk, a torsion spring is fixedly connected between the reset disk and the sample storage tube, and through the coordinated use of the torsion spring and the reset disk, the closing disk can be automatically closed by the action of the torsion spring after the sample is stored and retrieved, thereby improving the degree of product automation and avoiding forgetting to close the sample storage tube.

[0009] As a further solution of the utility model, one end of the sample storage tube away from the sampling head is fixedly connected to a protection box, and the reset disk is located in the protection box.

[0010] As a further solution of the utility model, the circumference of the reset disk is fixedly connected to a limiting block, and the limiting block is located between two of the guide blocks.

[0011] As a further solution of the utility model, two symmetrically arranged finger pressure plates are fixedly connected to the circumferential outer wall of the sample storage tube.

[0012] As a further solution of the utility model, one end of the sleeve is fixedly connected to a driving plate, and the driving plate is elliptical.

[0013] In the present application, when sampling is needed, the sleeve is rotated by the driving plate, and the sleeve rotates in the sample tube and drives the guide rod to rotate at the same time, and the guide rod drives the closing disk to rotate. After the second through groove on the closing disk coincides with the first through groove on the limit disk, the sample tube is connected to the sampling head, and sampling is carried out after the piston is moved to the end of the sample tube. When sampling, the sleeve is pulled, and the piston is driven to move, and the sample is extracted by the negative pressure principle. After the extraction is completed, the sleeve is released, and the sleeve is reset under the action of the torsion spring. At the same time, the closing disk is driven to rotate by the guide rod. After the first through groove and the second through groove are staggered, the sample tube is sealed, thereby avoiding splashing of the sample due to accidental contact with the equipment.

[0014] The embodiments of the present invention have the following beneficial effects:

[0015] In the utility model, the sealing disk and the limiting disk are used in combination, so that after the sampling of the sample tube is completed, the sample tube can be sealed by rotating the sealing disk, the operation is convenient and fast, and the splashing of the sample due to accidental contact with the equipment is avoided;

[0017] In the utility model, the sample storage tube is sealed by rotating the sealing disk, which is convenient and quick to operate, and at the same time avoids splashing of the sample due to accidental contact with the equipment. At the same time, through the action of the torsion spring, the sealing disk can be automatically sealed, thereby improving the degree of automation of the product and avoiding forgetting to seal the sample storage tube.
