Flow type counting chamber with detection inner cavity with adjustable thickness

Abstract

The invention discloses a flow type counting chamber with a detection inner cavity with adjustable thickness. The adjustable flow type counting chamber comprises a spring seat and a base placed on the spring seat, wherein the top end of the base is fixedly connected with an upper slide support spliced with an upper slide; the base is internally provided with a lower slide support spliced with a lower slide; the lower slide support is provided with a sealing groove; the sealing groove is internally provided with an O-shaped sealing ring; the lower slide is provided with at least two positioning blocks and is further provided with a sample feeding hole; the sample feeding hole is connected with a sample feeding pipe; the spring seat is provided with a plurality of blind holes and springs are arranged inside the blind holes; the base and the spring seat are connected through a locking screw rod; the bottom of the lower side support is tightly pressed on the springs on the spring seat; and a cavity is formed between the upper slide and the lower side and is the detection inner cavity. The counting chamber disclosed by the invention can realize the aim that the thickness of the detection inner cavity is adjustable, and further realizes the aim that the detection inner cavity is not easy to block in detecting and washing processes.

Description

technical field [0001] The invention relates to the technical field of urine microscope and blood microscope detection, in particular to a flow counting pool with adjustable thickness of detection inner cavity. Background technique [0002] In the current urine sediment analysis system using flow microscopy, the structure of the counting pool used is as follows: figure 1 As shown, it includes a base, a septum set on the base and an upper slide set on the septum, wherein the base and the upper slide are fixed, and an opening is provided in the center of the septum. The base, the septum slide and the upper slide are glued together to form a cavity, which is the detection inner cavity; holes connected with the detection inner cavity are opened on the base, and these holes are respectively connected with the sample injection tube and the sample discharge tube. tube connection. The detection process is as follows: the sample liquid enters the detection cavity through the sampli...

Problems solved by technology

The height of the detection inner cavity of the existing counting pool is fixed, about 100-200 μm. Since the height is small and cannot be adjusted, the detection inner cavity is easily blocked due to crystallization or large particles in the sample liquid during the detection and cleaning process. making subsequent testing impossible
