Abstract The present invention relates to a sample collection tool with a fiber structure that can improve sample collection efficiency. According to the present invention, as a capillary structure is formed between the longitudinal axes of each of the fiber strands from which the sample is collected, a type of capillary phenomenon can be induced between each fiber strand, and through this, sufficient capillary attraction is generated between each fiber strand to maintain the state in which the sample is received, resulting in an effect of improving the sample collection rate. Additionally, when the capillary height derivation formula is applied to the capillary structure formed by the fiber strands, the spacing distance between the fiber strands corresponds to the capillary diameter of the capillary structure, and the height of the capillary in which fluid and the like is received, may correspond to the distribution height of the sample contained between each fiber strand. At this time, as protrusions are formed on the outer surface of each fiber strand, the separation distance between each fiber strand may be as close as corresponds to the shape and size of the corresponding protrusion, and the separation distance between these fiber strands may correspond to the capillary diameter of the capillary structure. In this case, according to the capillary height derivation formula, the capillary diameter and the capillary height are inversely proportional, so the capillary diameter is ultimately reduced through the above-described protrusion configuration, resulting in the effect of further improving the sample collection rate corresponding to the capillary height. 본 발명은 검체의 채취 효율을 증진시킬 수 있는 섬유 구조를 지닌 검체 채취 도구에 관한 것으로, 본 발명에 따르면 검체가 채취되는 섬유 가닥들 각각의 길이축 사이에 모세관 구조가 형성됨에 따라, 각 섬유 가닥들 사이에는 일종의 모세관 현상이 유도될 수 있으며, 이를 통해 각 섬유 가닥들 사이에는 검체가 수용된 상태를 지속시킬 수 있는 충분한 모세관 인력이 발생하게 되어 검체의 채취율이 향상되는 효과가 발생하게 된다. 또한, 섬유 가닥들이 형성하는 모세관 구조에 모세관 높이 유도 공식이 적용되면, 섬유 가닥들의 이격 거리는 모세관 구조의 모세관 직경에 해당되고, 유체 등이 수용된 모세관 높이는 각 섬유 가닥 사이에 수용된 검체의 분포 높이에 대응될 수 있다. 이때, 각 섬유 가닥들의 외표면에 돌출부가 형성됨에 따라, 각 섬유 가닥들 사이의 이격 거리는 해당 돌출부의 형상과 크기에 대응되는 만큼 가까워질 수 있으며, 이러한 섬유 가닥들의 이격 거리는 모세관 구조의 모세관 직경에 해당될 수 있다. 이 경우, 모세관 높이 유도 공식에 따르면 모세관의 직경과 모세관 높이는 반비례하는 관계이므로, 결국 상술한 돌출부 구성을 통해 모세관 직경이 축소되어 모세관 높이에 대응되는 검체의 채취율이 더욱 향상되는 효과가 발생하게 된다.
