Problems solved by technology
[0003] In the past, nasal swabs were of one-piece structure, which caused the overall stiffness of the nasal swab, which may injure the inner wall of the nasal cavity when collecting nasal mucus. The medical staff must be more cautious and cautious, so it is inconvenient to use; in addition, the split type The nasal swab includes a hand-held rod and a sampling rod. The sampling rod is hinged to the hand-held rod. When the split nasal swab is used up, the hand-held rod and the sampling rod may not return to the state where the axes are collinear. It is inconvenient to adjust the angle of the container

The invention discloses a geometrically centered flexible nasal swab, which comprises a hand-held rod, one end of which is provided with a cylindrical section and a conical section, the cylindrical section is connected to the conical section, the conical section is arranged close to one end of the hand-held rod, and the conical section The small end of the sampling rod is set downward; one end of the sampling rod is provided with a sampling head, and the other end is provided with a conical connection block, the conical connection block is accommodated in the conical section, and the conical connection block is used for interference fit with the conical section; The elastic piece is accommodated in the cylindrical section. One end of the elastic piece is connected to the handle rod, and the other end is connected to the conical connecting block. The elastic piece is used to drive the conical connecting block to insert into the conical section. The conical connection block arranged on the sampling rod can move in the conical section, so that the sampling rod can rotate relative to the hand-held rod. When the sampling rod is inserted into the nasal cavity, it can enter along the nasal passage. The conical connection block is driven by the elastic piece Cooperate with the tapered section so that the axis of the sampling rod and the axis of the hand-held rod are collinear.
Description
technical field [0001] The invention relates to the technical field of sampling tools, in particular to a geometric centering flexible nasal swab. Background technique [0002] Nasal swab is a tool used to collect mucus containing cells in the nasal cavity, and nasal swabs are currently widely used. [0003] In the past, nasal swabs were of one-piece structure, which caused the overall stiffness of the nasal swab, which may injure the inner wall of the nasal cavity when collecting nasal mucus. The medical staff must be more cautious and cautious, so it is inconvenient to use; in addition, the split type The nasal swab includes a hand-held rod and a sampling rod. The sampling rod is hinged to the hand-held rod. When the split nasal swab is used up, the hand-held rod and the sampling rod may not return to the state where the axes are collinear. It is inconvenient to adjust the angle of the container. Contents of the invention [0004] The present invention aims to solve at...
