通常采用采样棒对液体样本进行收集吸收,该采样棒具有由吸收材料如垫或海绵形成的收集元件,收集元件连接到柱塞的一端。收集元件使得可以从液体源吸收足够体积的样本液体,收集元件中样本液体的存在导致收集元件内部膨胀。收集元件通常保持样本,直到操作收集元件释放样本。检测时,现有技术通常是采用挤压的方式将液体样本从采样棒的收集元件上挤脱出来,然后再添加到检测装置(例如侧流免疫分析装置)上进行检测;或者在有些检测中,还需要将挤脱出来的液体样本先与缓冲溶液进行混合/裂解等预处理,然后再添加到检测装置上进行检测。Liquid samples are typically collected and absorbed using a sampling stick having a collecting element formed of absorbent material such as a pad or sponge, which is attached to one end of a plunger. The collection element allows a sufficient volume of sample liquid to be absorbed from the liquid source, the presence of sample liquid in the collection element causing the interior of the collection element to expand. The collection element typically retains the sample until operation of the collection element releases the sample. During detection, the prior art usually squeezes the liquid sample out of the collection element of the sampling stick, and then adds it to the detection device (such as a lateral flow immunoassay device) for detection; or in some detections , It is also necessary to pretreat the extruded liquid sample with a buffer solution such as mixing/lysing, and then add it to the detection device for detection.
现有的操作中,使用收集瓶对收集元件上的液体样本进行收集,即将采样棒的收集元件端插入收集瓶中,将收集元件接触收集瓶体的侧壁或底部进行挤压使液体样本流出到收集瓶中进行样本收集。现有的收集瓶和采样棒存在的问题是,不能将采样棒之收集元件上的液体样本充分地挤压出来,即在挤压后,收集元件上仍然残留着较多的液体样本,从而仅有较少的液体样本用于后续的检测,因而很容易造成用于检测的液体样本量不够,从而造成检测失败或者检测结果不准确(尤其是当液体样本是唾液时,一般情况下,人或者动物在短时间内所能释放出的唾液的量是非常有限的,很容易导致液体样本量不足)。此外,当收集瓶中有缓冲液时,收集元件还会吸收和带走部分缓冲液或者液体样本与缓冲液的混合液,从而影响到检测结果的准确性。In the existing operation, the collection bottle is used to collect the liquid sample on the collection element, that is, the collection element end of the sampling rod is inserted into the collection bottle, and the collection element is pressed against the side wall or bottom of the collection bottle to make the liquid sample flow out into a collection bottle for sample collection. The problem with existing collection bottles and sampling sticks is that the liquid sample on the collection element of the sampling stick cannot be fully squeezed out, that is, after extrusion, there are still more liquid samples remaining on the collection element, so only There are fewer liquid samples for subsequent detection, so it is easy to cause insufficient liquid sample volume for detection, resulting in test failure or inaccurate test results (especially when the liquid sample is saliva, generally, people or The amount of saliva an animal can release in a short period of time is very limited, which can easily lead to insufficient fluid sample volume). In addition, when there is a buffer in the collection bottle, the collection element will also absorb and take away part of the buffer or the mixture of the liquid sample and the buffer, thereby affecting the accuracy of the detection result.

发明二、液体样本收集装置Invention 2. Liquid sample collection device
请参阅图5-8所示,本发明还提供一种液体样本收集装置100,该液体样本收集装置100包括如发明一所述的液体样本收集瓶10(为避免重复,将发明一中的内容全部并入发明二中,在发明二中不再对液体样本收集瓶10的具体结构进行详细描述)和取样器50。取样器50包括杆部52和连接至杆部下端54的汲液部56。汲液部56由吸水性能和排水性能均优越的材料制造,例如海棉、脱脂棉、纱布、特种纤维等。杆部52由硬质材料制成,杆部下端54呈圆饼状,其外周设有导槽58,该导槽58的形状和尺寸与瓶体内壁14上的导轨20相对应(图5和图6所示的导槽58为倾斜的,并且倾斜的方向与导轨20一致),杆部下端54的大小与瓶体内壁14所围成的空间相适应,从而既使导轨20能在导槽58内自由滑移,又能使导轨20与导槽58相互配合起到引导杆部下端54螺旋下降的作用。当将取样器50的杆部下端54插入液体样本收集瓶10内后,杆部下端54 的导槽58与瓶体内壁14上的导轨20相互配合,导引取样器50的杆部下端54在液体样本收集瓶内螺旋下降。当汲液部56的底部挤压垫部22的上表面时,两者之间的表面摩擦力减少了汲液部56的底部相对垫部22的相对滑动,然而导轨20导引杆部下端54带动汲液部56的上部继续扭转下降,从而杆部下端54一边向下挤压一边扭转汲液部56,产生拧挤汲液部56的效果(类似于拧湿毛巾),进而更加彻底地将液体样本从汲液部56排出到液体样本收集瓶10内,与收集瓶内的裂解液60(如图8所示)混合,形成裂解液与液体样本的混合液62(如图16所示)。5-8, the present invention also provides a liquid sample collection device 100, which includes the liquid sample collection bottle 10 as described in the first invention (in order to avoid repetition, the content in the first invention All are incorporated into the second invention, and the specific structure of the liquid sample collection bottle 10) and the sampler 50 will not be described in detail in the second invention. The sampler 50 includes a stem 52 and a dip 56 connected to a lower end 54 of the stem. The liquid-absorbing part 56 is made of a material with excellent water absorption and drainage properties, such as sponge, absorbent cotton, gauze, special fiber and the like. Rod 52 is made of hard material, and the lower end 54 of the rod is disc-shaped, and its periphery is provided with guide groove 58, and the shape and size of this guide groove 58 are corresponding to guide rail 20 on the bottle inner wall 14 (Fig. 5 and The guide groove 58 shown in Figure 6 is inclined, and the direction of inclination is consistent with the guide rail 20), the size of the bar lower end 54 is adapted to the space surrounded by the bottle inner wall 14, so that even the guide rail 20 can move in the guide groove 58, the guide rail 20 and the guide groove 58 can cooperate with each other to play the role of guiding the lower end 54 of the rod portion to spiral down. After the rod lower end 54 of the sampler 50 is inserted in the liquid sample collection bottle 10, the guide groove 58 of the rod lower end 54 cooperates with the guide rail 20 on the bottle inner wall 14, and the rod lower end 54 of the guide sampler 50 is in the Spiral descending inside liquid sample collection bottle. When the bottom of the dipping portion 56 presses against the upper surface of the pad portion 22, the surface friction between the two reduces the relative sliding of the bottom of the dipping portion 56 relative to the pad portion 22, while the guide rail 20 guides the lower end 54 of the stem portion. Drive the upper part of the liquid-absorbing part 56 to continue to twist and descend, so that the lower end 54 of the rod part twists the liquid-absorbing part 56 while squeezing downward, and produces the effect of squeezing the liquid-absorbing part 56 (similar to wringing a wet towel), and then more thoroughly The liquid sample is discharged from the drawing part 56 into the liquid sample collection bottle 10, and mixed with the lysate 60 in the collection bottle (as shown in FIG. 8 ) to form a mixed solution 62 of the lysate and the liquid sample (as shown in FIG. 16 ). .
如在发明一中所述,瓶体12的内壁14之圆柱体部18展开后,内壁14上的导轨20自上而下呈倾斜的直线状或者平滑曲线状。请参阅图14,平滑曲线状的导轨有利于在开始下降阶段时,导轨20和导槽58引导杆部下端54加快下降的速度,从而对汲液部产生更强烈的向下挤压,而在接近下降结束阶段时,导轨20和导槽58引导杆部下端54产生更强烈的扭转,从而对汲液部56产生更好的拧挤效果,从汲液部56拧挤出更多的液体样本。As described in the first invention, after the cylinder portion 18 of the inner wall 14 of the bottle body 12 is unfolded, the guide rail 20 on the inner wall 14 is in the shape of an inclined straight line or a smooth curve from top to bottom. Please refer to FIG. 14 , the smooth curved guide rail is beneficial to the guide rail 20 and the guide groove 58 to guide the lower end 54 of the rod part to accelerate the descending speed at the beginning of the descending stage, thereby exerting a stronger downward extrusion on the liquid extraction part, while in the When approaching the end of the descent, the guide rail 20 and the guide groove 58 guide the lower end 54 of the rod part to produce a stronger twist, thereby producing a better wringing effect on the liquid drawing part 56, and squeezing out more liquid samples from the liquid drawing part 56 .
如图21-23所示,为了减少汲液部56的底部与垫板22之上表面之间的相对滑动,在垫板22的上表面和取样器之汲液部56的底部设有相互配合的凸起28和凹陷30,该等凸起和凹陷相互配合减少了汲液部56的底部与垫板22之上表面之间的相对滑移,增强了对汲液部56的拧挤效果。既可以在垫板22的上表面设置凹陷30(该凹陷也可以是通孔24)和在取样器之汲液部56的底部设置凸起28(如图22所示),也可以在垫板22的上表面设置凸起28和在取样器之汲液部56的底部设置凹陷30(如图23所示),或者使汲液部56的底部和垫板22的上表面做成粗糙的表面,以增加两者之间的摩擦力。优选地,对汲液部56的底部进行硬化处理,使其相对于汲液部的其他部分来说具有更高的硬度,从而更加有利于减少汲液部56的底部与垫板22上表面之间的滑移,提高了对汲液部56的拧挤效果,进而提高了对汲液部56的液体样本排脱率。As shown in Figures 21-23, in order to reduce the relative sliding between the bottom of the liquid absorbing portion 56 and the upper surface of the backing plate 22, the upper surface of the backing plate 22 and the bottom of the liquid absorbing portion 56 of the sampler are provided with mutual cooperation. The protrusions 28 and the depressions 30 cooperate with each other to reduce the relative slippage between the bottom of the dipping part 56 and the upper surface of the backing plate 22, and enhance the wringing effect on the dipping part 56. Both can be provided with depression 30 (this depression also can be through hole 24) on the upper surface of backing plate 22 and be provided with protrusion 28 (as shown in Figure 22) at the bottom of the dipping part 56 of sampler, also can be on backing plate The upper surface of the sampler 22 is provided with a protrusion 28 and a depression 30 (as shown in Figure 23 ) at the bottom of the dipping portion 56 of the sampler, or the bottom of the dipping portion 56 and the upper surface of the backing plate 22 are made rough. , to increase the friction between the two. Preferably, the bottom of the dipping portion 56 is hardened so that it has a higher hardness compared to other parts of the dipping portion, so that it is more conducive to reducing the gap between the bottom of the dipping portion 56 and the upper surface of the backing plate 22. The sliding between them improves the squeezing effect on the liquid-absorbing part 56, and further improves the discharge rate of the liquid sample from the liquid-absorbing part 56.
如图24所示,相互配合的导轨20与导槽58为一对。如图25-29所示,为提高导引的平稳性,相互配合的导轨20与导槽58也可以是均匀分布的两对、三对、四对、五对或者六对,如此可以提高对汲液部56的拧挤效果,进一步提高从汲液部56拧挤出液体样本的效率。As shown in FIG. 24 , the guide rail 20 and the guide groove 58 that cooperate with each other form a pair. As shown in Figures 25-29, in order to improve the stability of the guide, the guide rails 20 and the guide grooves 58 that cooperate with each other can also be two pairs, three pairs, four pairs, five pairs or six pairs that are evenly distributed, so that the pairing can be improved. The wringing effect of the liquid drawing part 56 further improves the efficiency of wringing out the liquid sample from the liquid drawing part 56 .
如图2、图6所示,导轨20的底部与垫板22之上表面之间的距离“L”大于等于2.5毫米并且小于等于35.0毫米,该距离“L”能使取样器50的杆部下端54卡扣在导轨20的底部(如图17、18所示)。如此设计的优点是:在操作人员放手后仍然能使汲液部56保持在被扭转压缩的状态。As shown in Fig. 2 and Fig. 6, the distance "L" between the bottom of the guide rail 20 and the upper surface of the backing plate 22 is greater than or equal to 2.5 millimeters and less than or equal to 35.0 millimeters, and this distance "L" can make the rod portion of the sampler 50 The lower end 54 is buckled on the bottom of the guide rail 20 (as shown in FIGS. 17 and 18 ). The advantage of such a design is that the liquid-absorbing part 56 can still be kept in a twisted and compressed state after the operator lets go.
如图19、图20所示,导轨20之底部的下表面与取样器50之杆部下端56的部分上表面为一对相互配合的斜面32、34。在顺向(如图19、20是箭头方向所示)旋转取样器的过程中,该一对斜面具有导引作用,并且使导轨20之底部进一步向下挤压取样器50的杆部下端54,在操作人员放手后仍然使取样器之杆部下端受到导轨20之底部的挤压。As shown in FIGS. 19 and 20 , the lower surface of the bottom of the guide rail 20 and the upper surface of part of the lower end 56 of the rod portion of the sampler 50 are a pair of inclined surfaces 32 and 34 that cooperate with each other. In the process of rotating the sampler in the forward direction (as shown by the arrows in Figures 19 and 20), the pair of inclined surfaces have a guiding effect, and make the bottom of the guide rail 20 further press the lower end 54 of the rod portion of the sampler 50 downward. , still make the lower end of the rod portion of the sampler be squeezed by the bottom of the guide rail 20 after the operator lets go.
