Problems solved by technology

[0003] Generally, most of the needle washing pools of the existing inspection instruments use a single sink cleaning mode, that is, the sampling needles are kept clean through the washing of water flow, but this will cause the phenomenon of wall hanging on the outer wall of the needle. In order to eliminate the wall hanging phenomenon, many manufacturers have treated the outer wall of the needle with a hydrophobic coating, which increases the unit price of the needle

Abstract

The invention provides a needle washing pool. The needle washing pool comprises a base and an upper cover, and is characterized in that the base further comprises an intake port; the intake port is formed in the side wall of an accommodating part of the base for penetrating through the side wall, and is used for injecting positive pressure air; the upper cover further comprises a second concave part and at least one exhaust port; an air storage cavity is formed between the second concave part and the base for storing the positive pressure air; the exhaust port is formed in the second concave part for penetrating through the side wall of the upper cover to communicate the air storage cavity with a sample charging needle part; after the positive pressure air is injected in the sample charging needle part, thrust towards an inlet of a sample charging needle is applied to the sample charging needle to shift out the sample charging needle from the sample charging needle part; and meanwhile,the remained part of cleaning liquid hung on the sample charging needle is shifted, and is discharged from the needle washing pool through a waste liquid part, so that the cleaning effect is excellent, and the cross contamination is low.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to a needle washing pool. Background technique [0002] Generally, blood samples are collected in test tubes, and then the samples are transferred to the sample tank through the sample needle, and then various reagents are added through the sample needle to perform sample pretreatment, and then the pretreated samples are optically, Acquisition of electronic, vibration and other signals. In this way, a device for cleaning the sampling needle is needed, thereby reducing cross-contamination between samples and ensuring the accuracy of the test. [0003] Generally, most of the needle washing pools of the existing inspection instruments use a single sink cleaning mode, that is, the sampling needles are kept clean through the washing of water flow, but this will cause the phenomenon of wall hanging on the outer wall of the needle. In order to eliminate the wall hanging phenomenon, m...
