Description

Technical Field

[0001] This utility model relates to the field of biological gene sampler technology, specifically a sampler for biological gene detection. Background Technology

[0002] A biological sampler for gene testing is a tool specifically designed to collect biological samples (such as blood, saliva, hair, oral mucosal cells, etc.) from humans or other organisms for gene testing and analysis. It is designed to ensure sample integrity, non-contamination, and traceability, providing a qualified sample basis for subsequent experimental steps such as gene extraction, amplification, and sequencing.

[0003] In the field of biological gene testing, saliva sampling is widely used due to its non-invasive and convenient characteristics. The structural design of the saliva sampler directly affects the sampling efficiency and sample quality. Most existing saliva samplers adopt a combination structure of "funnel + collection tube", the core of which is to guide saliva into the tube through the funnel to complete sample collection.

[0004] However, traditional samplers often use threaded connections between the funnel and the tube, which require manual tightening. Uneven tightening can lead to poor sealing and leakage. Therefore, a sampler for biological gene detection is needed. Utility Model Content

[0005] The purpose of this invention is to provide a sampler for biological gene detection, which solves the problems mentioned in the background art.

[0006] This application provides a sampler for biological gene detection, including a collection tube, a fixing ring fixedly sleeved on the outside of the collection tube, a funnel at the top of the collection tube, a mounting frame fixedly connected to the bottom of the funnel, an insertion rod fixedly connected to the bottom of the mounting frame, the insertion rod passing through the fixing ring, a screw threaded through the outer wall of the fixing ring, a rubber block fixedly connected to the end of the screw facing the insertion rod, the rubber block abutting against the insertion rod, and a connecting block fixedly connected to the end of the screw away from the rubber block.

[0007] In use, the mounting bracket connects the insertion rod to the bottom of the funnel. When the funnel is installed at the top of the collection tube, the insertion rod passes through the fixing ring. Then, the screw can be manually turned through the connecting block to fix the screw and the insertion rod in place, thus securing the funnel. The rubber block on the end face of the screw prevents direct contact between the screw and the insertion rod, reducing wear on the insertion rod. When collecting saliva for biological gene testing, personnel can rinse their mouths with water beforehand to avoid contamination by food residue or impurities. Then, they can spit naturally secreted saliva into the collection tube through the funnel. The collection tube is pre-filled with nucleic acid preservation solution. After the saliva enters, it will mix thoroughly with the preservation solution, quickly stabilizing the oral epithelial cells and nucleic acid components in the sample and preventing degradation. Once the collection volume reaches the target, the funnel is removed, and the opening of the collection tube is tightly sealed with a sealing plug with a silicone sealing ring to complete the sampling.

[0008] Optionally, the top opening of the collection tube is covered with a protective edging.

[0009] By adopting the above technical solution, the protective edging can prevent the funnel from colliding with the opening of the collection tube, thus protecting the collection tube.

[0010] Optionally, the front wall of the collection tube is provided with graduations.

[0011] By adopting the above technical solution, the amount of saliva collected can be observed through the scale.

[0012] Optionally, the outer wall of the connecting block is provided with anti-slip texture.

[0013] By adopting the above technical solution, the anti-slip effect of the connecting block can be increased, thus preventing the slippage of the hand.

[0014] Optionally, two insertion rods are provided, and the two insertion rods are arranged symmetrically on the left and right.

[0015] By adopting the above technical solution, the stability and firmness of the funnel installation are further improved.

[0016] Optionally, the insertion rod is made of metal.

[0017] By adopting the above technical solution, it is beneficial to improve the rigidity of the insertion rod and avoid bending of the insertion rod.

[0018] Optionally, the insertion rod has a cuboid structure.

[0019] By adopting the above technical solution, it is beneficial to increase the contact area between the insert rod and the screw rod, thereby improving the fixing effect of the screw rod on the insert rod.

[0020] Optionally, the retaining ring is made of stainless steel.

[0021] By adopting the above technical solution, it is beneficial to increase the corrosion resistance of the fixing ring and extend its service life.

[0022] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0023] The technical solution of this application connects the insert rod to the bottom of the funnel using a mounting bracket. When the funnel is installed at the top of the collecting pipe, the insert rod passes through the fixing ring. Then, the screw can be manually tightened through the connecting block to make the screw and the insert rod abut and fix it, thus completing the fixation of the funnel. The rubber block on the end face of the screw can prevent the screw and the insert rod from directly contacting each other, reducing wear on the insert rod. Through the above structural combination, the problem of poor sealing caused by uneven tightening force when the traditional funnel and collecting pipe are connected by threads can be effectively solved.
