Description

Technical Field

[0001] The utility model relates to the field of gene detection, in particular to a sample storage device for gene detection. Background Art

[0002] Genetic testing is a technology that detects DNA through blood, body fluids or cells. It is used for diagnosis of genetic diseases, tumor diagnosis and prognosis assessment, drug response prediction, etc. Genetic samples usually need to be properly preserved after collection to maintain the integrity and stability of the samples. This solution specifically involves a sample preservation device for genetic testing;

[0003] When using the existing sample preservation device for genetic testing, the preservation liquid is easily poured out when taking out the sample, which is inconvenient for taking and placing the sample, and it is inconvenient to separate the sample from the preservation liquid when taking it out. In addition, some samples, such as hair, are not completely soaked in the preservation liquid during the preservation process, making it inconvenient to press and position them, which has a certain impact on actual use.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a sample storage device for gene detection includes a tube body 1, a pick-up and placement component 2 is installed on the top of the tube body 1, a positioning component 3 is installed on the top of the pick-up and placement component 2, the pick-up and placement component 2 includes a screw cap 4, the screw cap 4 is sleeved on the top of the tube body 1, a positioning plug 5 is movably installed at the bottom of the screw cap 4 and located inside the tube body 1 near the top, four slide rails 6 are installed on the periphery of the positioning plug 5, four slide grooves 8 are opened on the inner wall of the tube body 1 near the top, a clamping shaft 7 is installed on the top of the positioning plug 5 and passes through the inside of the screw cap 4, a connecting rod 10 is fixedly installed at the bottom of the positioning plug 5 near the edge, a bottom of the connecting rod 10 is fixedly installed with a chassis 11, and a plurality of through holes 12 are opened through the upper and lower parts of the chassis 11.

[0023] In this embodiment, the screw cap 4 is sleeved on the outer periphery of the tube body 1 through the screw groove 9 and is threadedly connected to the top end. The clamping shaft 7 passes through the interior of the screw cap 4 and is movably rotatable. The tube body 1 is opened or sealed by rotating the screw cap 4, and the positioning plug 5 is connected and rotated through the clamping shaft 7.

[0024] In this embodiment, the four slide rails 6 and the slide grooves 8 are all arranged in a ring shape, the slide rails 6 are located in the slide grooves 8 and are slidable, and the positioning plug 5 slides through the slide rails 6 and the slide grooves 8 to prevent it from rotating with the rotary cover 4.

[0025] In this embodiment, the positioning plug 5 is located inside the tube body 1 near the top and is matched with each other. The bottom plate 11 and the positioning plug 5 are on the same vertical line. The sample is supported by the bottom plate 11, which is convenient for placing, storing and taking out the sample.

[0026] In this embodiment, the positioning assembly 3 includes a screw 13, which is movably mounted inside the card shaft 7 and the positioning plug 5. A pressure plate 14 is movably mounted at the bottom of the screw 13. A plurality of identical through holes 12 are provided through the upper and lower parts of the pressure plate 14. A knob 15 is fixedly mounted on the top of the screw 13. By rotating the knob 15, the pressure plate 14 slides up and down, pressing the sample downward and immersing it in the preservation solution.

[0027] In this embodiment, the screw 13 passes through the interior of the clamping shaft 7 and the positioning plug 5 and is threadedly connected. The pressure plate 14 is located inside the tube body 1 and is matched with each other. The screw 13 rotates and slides up and down under the action of the thread, causing the pressure plate 14 to slide inside the tube body 1.

[0028] In this embodiment, the outer side of the pressure plate 14 is sleeved on the inner side of the connecting rod 10 and is arranged to slide up and down. The screw 13 and the pressure plate 14 are movably connected through a bearing. The pressure plate 14 slides up and down through the connection of the bearing and is prevented from following the rotation, thereby reducing damage to the sample.

[0029] It should be noted that the utility model is a sample storage device for genetic testing. When in use, firstly, samples such as blood, saliva, tissue, etc. for genetic testing are placed in the tube body 1. When samples such as hair, nails, and dandruff are taken and placed, the samples are placed on the top of the bottom plate 11, and then the bottom plate 11 is extended into the tube body 1, so that the slide rail 6 of the positioning plug 5 is inserted into the slide groove 8, the screw cover 4 is rotated by the clamping shaft 7, and is connected to the tube body 1 through the thread of the screw groove 9. At the same time, the positioning plug 5 drives the sample to slide downward and be stored in the tube body 1. When it is taken out again, the sample is taken out through the bottom plate 11. Since some samples such as hair need to be added to the preservation solution for preservation and are not completely infiltrated, the preservation solution added in the tube body 1 flows through the through hole 12, and the screw 13 is rotated by rotating the knob 15. The screw 13 rotates and drives the pressure plate 14 to slide downward under the action of the thread, pressing the sample downward to make it completely infiltrated.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
