[0002] Currently, in the field of biomedical scientific research, auxiliary tools are needed to transfer liquid samples, that is, to transfer samples from one place to another. Among these auxiliary tools, the most common is the Pasteur pipette.

[0003] As disclosed in Publication No. CN216172438U, an invertible Pasteur straw consists of a straw body and a portable frame. A buckle is fixed to the end of the straw body at the suction pouch. A locking slot is provided on one side of the portable frame. The buckle is inserted into the locking slot and rotated to fix the straw body to the portable frame. A flat plate is fixed to the other side of the portable frame away from the opening of the locking slot, and a writing area is provided on the outer wall of the locking slot. This invention's Pasteur straw and its matching inverted frame only contact the suction pouch, minimizing the possibility of contamination of the straw due to contact between the straw body and the frame. Furthermore, the connection structure between the inverted frame and the straw body is simple and inexpensive, and locking and unlocking are convenient.

[0004] However, in the aforementioned Pasteur straw, the liquid inside the straw is prone to sedimentation when it is inverted, which reduces the efficacy of the medicine. Therefore, there is a need to propose an invertible Pasteur straw. Utility Model Content
