    Abstract: An apparatus and method provide automated collection and transfer of particles from a liquid suspension to a glass slide for visual examination. A solution which contains particles, for example cells, is drawn through a filter element so that particles too large to pass through the filter element collect against a first surface of the filter element. A transfer fluid, such as alcohol, is applied from a second surface of the filter element to the first surface, to transfer cells from the filter element to a glass slide positioned adjacent the filter element. An alternative transfer mechanism applies a selected pneumatic signal to the filter element for transferring collected cells to the viewing slide. The apparatus includes a device for dispersing the liquid suspension of particles prior to the collection process and particles collect against the filter element with a spatial distribution advantageous for visual examination. The transfer operation maintains this spatial distribution. The cell-dispersing device and the filter element are on a common structure, for unitary movement, and which is readily disposable and replaceable for each sample of particles.

    Abstract translation: 一种装置和方法提供从液体悬浮液到玻璃载玻片的自动收集和转移以进行目视检查。 包含颗粒（例如细胞）的溶液通过过滤元件被吸引，使得太大而不能通过过滤元件的颗粒聚集在过滤元件的第一表面上。 转移流体，例如醇，从过滤元件的第二表面施加到第一表面，以将细胞从过滤元件转移到位于过滤元件附近的玻璃载玻片。 替代的传送机构将所选择的气动信号应用于过滤元件，用于将收集的单元传送到观看幻灯片。 该装置包括用于在收集过程之前分散颗粒的液体悬浮液的装置，并且具有有利于目视检查的空间分布的颗粒聚集在过滤元件上。 转移操作保持这种空间分布。 细胞分散装置和过滤元件在共同的结构上，用于单一运动，并且对于每个颗粒样品而言，其易于一次性和可更换。
