Description

测试片 技术领域
本发明涉及实验设备技术领域,具体而言,涉及一种测试片。
背景技术
测试片是近年来发展起来的一种微生物快速检测装置,主要包括上层片和下层片,在使用时将需要测试的物质连同培养基放在下层片上,再盖上上层片。为了保证测试的准确性,防止大气中的微生物进入到上层片和下层片之间。很多测试片依靠胶粘剂,将上层片和下层片的边沿粘合。
但是,上述的测试片在实际使用过程中,胶粘剂可能会对某些需要测试的微生物生长会有一定影响。另外,由于上层片和下层片的边沿依靠胶粘剂粘合,也不利于某些微生物对于空气的需要。
发明内容
本发明的主要目的在于提供一种测试片,以解决现有技术中测试片为了防止微生物进入到上层片和下层片之间而会造成对某些微生物检测产生影响的技术问题。
为了实现上述目的,本发明提供了一种测试片,包括上层片和下层片,下层片的顶面设置有第一环形凸筋和间隔设置在第一环形凸筋外侧的第二环形凸筋,第一环形凸筋的内侧围成测试空间,第一环形凸筋和第二环形凸筋之间形成沉降空间。
在一个实施方式中,上层片的底面设置有第三环形凸筋,在上层片和下层片扣合时,第三环形凸筋位于第一环形凸筋和第二环形凸筋之间,并且第三环形凸筋的至少部分与第一环形凸筋和第二环形凸筋间隔形成连通大气和测试空间的气道,气道在第三环形凸筋和第二环形凸筋之间呈下降趋势,气道在第三环形凸筋和第一环形凸筋之间呈上升趋势,述气道在第一环形凸筋和第二环形凸筋之间形成沉降空间。
在一个实施方式中,第一环形凸筋和/或第二环形凸筋和/或第三环形凸筋的截面为拱形。
在一个实施方式中,第一环形凸筋和/或第二环形凸筋和/或第三环形凸筋的截面为半圆形。
在一个实施方式中,气道的宽度与半圆形的半径之比小于0.5。
在一个实施方式中,第一环形凸筋和/或第二环形凸筋和/或第三环形凸筋的截面为三角形或梯形。
在一个实施方式中,测试片还包括放置在测试空间内的培养基。
在一个实施方式中,下层片和上层片为圆形,第一环形凸筋、第二环形凸筋和/或第三环形凸筋为圆环形。
在一个实施方式中,下层片和上层片为多边形,第一环形凸筋、第二环形凸筋和/或第三环形凸筋为多边形环。
应用本发明的技术方案,没有采用胶粘剂将上层片和下层片的边沿粘合,这样上层片和下层片之间的间隙就可以用来通气。当空气从大气通往测试空间时,由于第二环形凸筋的存在,会产生康达效应,使得气流在第二环形凸筋的引导下,到达沉降空间,之后再通过第一环形凸筋的引导进入到测试空间中。在此过程,空气中的微生物或者杂质就会沉降在沉降空间,避免进入到测试空间内影响测试的精度。这样一来,就可以在保证通气性的基础上,还可以对影响测试的微生物或杂质起到阻隔的作用。
除了上面所描述的目的、特征和优点之外,本发明还有其它的目的、特征和优点。下面将参照图,对本发明作进一步详细的说明。

具体实施方式
需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
为了使本技术领域的人员更好地理解本发明方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分的实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
需要说明的是,本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便这里描述的本发明的实施例。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
需要注意的是,这里所使用的术语仅是为了描述具体实施方式,而非意图限制根据本申请的示例性实施方式。如在这里所使用的,除非上下文另外明确指出,否则单数形式也意图包括复数形式,此外,还应当理解的是,当在本说明书中使用术语“包含”和/或“包括”时,其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
图1和图2示出了本发明的测试片的实施例一,该测试片包括上层片10和下层片20,下层片20的顶面设置有第一环形凸筋21和间隔设置在第一环形凸筋21外侧的第二环形凸筋22,上层片10的底面设置有第三环形凸筋11。第一环形凸筋21的内侧围成测试空间a,在上层片10和下层片20扣合时,第三环形凸筋11位于第一环形凸筋21和第二环形凸筋22之间,并且第三环形凸筋11的至少部分与第一环形凸筋21和第二环形凸筋22间隔形成连通大气和测试空间a的气道b。气道b在第三环形凸筋11和第二环形凸筋22之间呈下降趋势,气道b在第三环形凸筋11和第一环形凸筋21之间呈上升趋势,气道b在第一环形凸筋21和第二环形凸筋22之间形成沉降空间c。
应用本发明的技术方案,没有采用胶粘剂将上层片10和下层片20的边沿粘合,这样上层片10和下层片20之间的间隙就可以用来通气。由于第一环形凸筋21、第二环形凸筋22和第三环形凸筋11形成了气道b结构,空气在大气和测试空间a之间流通就必须经过气道b。当空气从大气通往测试空间a时,先经过下降趋势的气道b到达沉降空间c,再通过上升趋势的气道b通往测试空间a,在此过程,空气中的微生物或者杂质就会沉降在沉降空间c,避免进入到测试空间a内影响测试的精度。这样一来,就可以保证通气性的基础上,还可以对影响测试的微生物或杂质起到阻隔的作用。
同理,上述的气道b也会对测试空间a通往大气的气体起到阻隔的作用,避免测试空间a中的测试物质污染实验环境或危害实验环境。
关于图2和图3需要说明的是,在实际使用测试片时,当上层片10和下层片20扣合,上层片10和下层片20之间还是会存在间隙的,图2和图3仅是以一种便于理解的放大结构图来说明间隙的存在以及本发明的原理。
如图2所示,在实施例一的技术方案中,第一环形凸筋21、第二环形凸筋22和/或第三环形凸筋11的截面为拱形。这样,可以形成康达气流,引导气流流通缓慢,让气流中的微生物或者杂质易于沉降在沉降空间c中。优选的,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11的截面为半圆形。经过试验,气道b的宽度与半圆形的半径之比小于0.5,可以起到更良好的沉降效果。
作为一种更为优选的实施方式,测试片还包括放置在测试空间a内的培养基。培养基可以是凝胶式培养基,也可以是干粉式培养基,培养基的类型可以根据需要提前在测试空间a内放置。
如图1所示,在实施例一的技术方案中,下层片20和上层片10为圆形,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11为圆环形。
图3示出了本发明的测试片的实施例二,实施例二和实施例一相比的区别在于,在实施例二的技术方案中,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11的截面为梯形。
作为另一种可选的实施方式,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11的截面为三角形也是可行的。
图4示出了本发明的测试片的实施例三,实施例三和实施例一相比的区别在于,在实施例三的技术方案中,下层片20和上层片10为三角形,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11为三角形环。
图5示出了本发明的测试片的实施例四,实施例四和实施例一相比的区别在于,在实施例四的技术方案中,下层片20和上层片10为正方形,第一环形凸筋21、第二环形凸筋22和第三环形凸筋11为正方形环。
作为其他的可选的实施方式,下层片20和上层片10也可以为五边形或者六边形,相对应的第一环形凸筋21、第二环形凸筋22和第三环形凸筋11则为五边形环或者六边形环。
图6示出了本发明的测试片的实施例五的技术方案,实施例五的技术方案和上述实施例相比,区别在于,取消了包括上层片10上的第三环形凸筋11,而仅保留下层片20的顶面设置的第一环形凸筋21和间隔设置在第一环形凸筋21外侧的第二环形凸筋22,第一环形凸筋21的内侧围成测试空间a,第一环形凸筋21和第二环形凸筋22之间形成沉降空间c。应用本发明的技术方案,没有采用胶粘剂将上层片10和下层片20的边沿粘合,这样上层片10和下层片20之间的间隙就可以用来通气。当空气从大气通往测试空间a时,由于第二环形凸筋22的存在,会产生康达效应,使得气流在第二环形凸筋22的引导下,到达沉降空间c,之后再通过第一环形凸筋21的引导进入到测试空间a中。在此过程,空气中的微生物或者杂质就会沉降在沉降空间c,避免进入到测试空间a内影响测试的精度。这样一来,就可以在保证通气性的基础上,还可以对影响测试的微生物或杂质起到阻隔的作用。
除非另外具体说明,否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。同时,应当明白,为了便于描述,附图中所示出的各个部分的尺 寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论,但在适当情况下,所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中,任何具体值应被解释为仅仅是示例性的,而不是作为限制。因此,示例性实施例的其它示例可以具有不同的值。应注意到:相似的标号和字母在下面的附图中表示类似项,因此,一旦某一项在一个附图中被定义,则在随后的附图中不需要对其进行进一步讨论。
为了便于描述,在这里可以使用空间相对术语,如“在……之上”、“在……上方”、“在……上表面”、“上面的”等,用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是,空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如,如果附图中的器件被倒置,则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而,示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位),并且对这里所使用的空间相对描述作出相应解释。
在本发明的描述中,需要理解的是,方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,在未作相反说明的情况下,这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作,因此不能理解为对本发明保护范围的限制;方位词“内、外”是指相对于各部件本身的轮廓的内外。
以上所述仅为本发明的优选实施例而已,并不用于限制本发明,对于本领域的技术人员来说,本发明可以有各种更改和变化。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
