Description

Technical Field

[0001] This utility model relates to the field of NGS detection technology, specifically to an NGS detection sample collector. Background Technology

[0002] Sterility testing is a method for checking whether drugs, medical devices, raw materials, excipients, and other products subject to pharmacopoeia requirements are sterile. Traditional sterility testing methods mainly include pharmacopoeia sterility testing, adenosine triphosphate (ATP) bioluminescence assay, and nucleic acid amplification assay, but different methods have their own characteristics and limitations (Song Guangyan, Feng Zhen, Pan Yingying, Research on the Application of Flow Cytometry in Drug Sterility Testing. Chinese Pharmacist, 2012, 21(2):p.342-345). In the fields of drug and medical device production, distribution, and regulation, sterility testing is a necessary means to ensure drug quality and reduce adverse drug reactions, especially for high-risk sterile preparations, where sterility testing is of great significance.

[0003] Existing samplers are prone to leakage during sample transfer when collecting cell-derived drugs. Furthermore, external impurities are also collected along with the sampler during the collection process, which can easily lead to sample contamination. Therefore, an NGS detection sample collector is proposed. Utility Model Content

The guide plate 150 and the positioning post 160, located within the housing 110, guide the main guide block 230 during lifting and lowering. The lifting sampling assembly 200 includes a main guide block 230 disposed on the inner wall of the housing 110, with a handle 120 mounted on the top of the main guide block 230. A connecting rod 210 has a cutting board 220 mounted on the side away from the main guide block 230. A limiting groove 240 and a guide groove 250 are provided on the outer wall of the main guide block 230. A telescopic rod 270 is provided on the inner wall of the limiting groove 240. A U-shaped positioning frame 260 is mounted on the outer wall of the telescopic rod 270. A spring 280 is sleeved on the outer wall of the telescopic rod 270. When the main guide block 230 descends, the positioning post 160 contacts the U-shaped positioning frame 260, and the spring 280 is compressed. After collection, the main guide block 230 is reset. The lower collection assembly 300 includes a triangular collection assembly 310 disposed on the outer wall of the main guide block 230. A rotating plate 320 is provided on the outer wall of the triangular collection assembly 310. A rotating assembly 330 is installed on the inner wall of the rotating plate 320. The rotating assembly 330 includes a left connecting block 331 disposed on the outer wall of the rotating plate 320. A left connecting arm 332 is installed on the outer wall of the left connecting block 331. A right connecting block 333 is installed on the side of the rotating plate 320 away from the left connecting block 331. A right connecting arm 334 is installed on the outer wall of the right connecting block 333. A positioning shaft 335 is provided on the outer wall of the right connecting arm 334. The acquisition assembly 400 includes a mounting shaft 410 disposed on the outer wall of the main guide block 230. An extension rod 420 is installed on the side of the mounting shaft 410 away from the main guide block 230. A connecting plate 430 is installed on the side of the extension rod 420 away from the mounting shaft 410. A fixing rod 440 is provided on the outer wall of the connecting plate 430. The wall is equipped with a collection frame 450, in which the connecting plate 430, fixing rod 440, and collection frame 450 are integrated.

The rotating plate 320 is symmetrically distributed on the outer wall of the triangular collecting assembly 310, and is rotatably connected to the triangular collecting assembly 310. The limiting groove 240 is sleeved with the positioning post 160, and is also slidably connected to it. This ensures that when the main guide block 230 slides inside the housing 110, the guide plate 150 and the positioning post 160 can limit the movement of the main guide block 230, effectively preventing positional displacement of the main guide block 230 during movement.

[0026] Working principle: When the device is needed, the worker holds the handle 120 and moves it to a suitable position, then presses down the cutting board 220, causing the triangular collection component 310 to move downward. After the triangular collection component 310 moves downward, the rotating plate 320 opens, and the sample is collected through the collection rack 450 inside the triangular collection component 310.
