Abstract
Description
Technical Field
[0001] The utility model relates to the field of sample cups, in particular to a flow type sample cup assembly. Background Art
[0002] The existing sample cup ends are fastened to the frame with metal screws. The opening above the sample cup is very likely to splash out corrosive liquid, causing the metal screws to rust. Over time, the metal screws cannot be turned or the nuts are twisted during disassembly.
[0003] The existing light shield assembly of the sample cup assembly is composed of two independent parts, and the diode and the photosensitive cell are fixed to one of the parts respectively. The concentricity of the diode and the photosensitive cell depends on the installation quality of the two parts. The hidden buckle used in the light shield assembly of the prior art is time-consuming and troublesome to disassemble, and the card slot seat is easily broken, which is equivalent to a one-time buckle fixation.
[0004] The existing sample cups have two interfaces for air intake, located at the front and the bottom of the sample cup. The sample cup with the interface located at the front (for white blood cell detection) can only be equipped with the rear chamber electrode, because the fixings of the rear chamber electrode occupy the space on the left and right sides of the sample cup. The sample cup with the interface located at the bottom (for red blood cell detection) can only be equipped with a light shield assembly, because the fixings of the light shield assembly occupy the space at the front and the back.
