Problems solved by technology

At present, the cleaning methods commonly used in the market are to use flowing liquid to wash away the residual liquid on the pipe wall, or directly use a pressure washing device to wash directly, but only a certain part or angle of the surface of the sampling needle can be cleaned, which is different. To a certain extent, the cleaning is not clean, and the risk of cross-contamination is greater

Abstract

The invention discloses a sampling needle washing device which comprises a swab and a rotor installed in an inner cavity. The swab is provided with the inner cavity, and a liquid inlet and a liquid outlet are formed in the side wall of the swab. The rotor is provided with a washing cavity allowing a sampling needle to be inserted in, at least one blade is arranged on the outer side of the rotor, at least one liquid communicating port is formed in the side wall of the rotor, and the inner cavity and the washing cavity communicate with each other through the liquid communicating ports. The sampling needle is inserted in the washing cavity, washing liquid flows into the inner cavity through the liquid inlet and then flows away through the liquid outlet, the washing liquid flows in the inner cavity in a fixed direction and drives the rotor to rotate, the washing liquid in the inner cavity flows into the washing cavity through the liquid communicating ports, and the washing liquid in the washing cavity is driven by the rotor to scour the sampling needle in all directions. By the adoption of the sampling needle washing device, a washing effect is greatly improved, and the probability ofcross infection of sampling needles is reduced.

Description

technical field [0001] The invention relates to a sampling needle cleaning device in the field of medical testing instruments. Background technique [0002] During the use of the chromatography technology analyzer, after the sampling needle draws the blood sample in the test tube, the blood sample is left on the inner and outer surfaces of the needle to avoid cross-contamination and affect the next test, and the residual blood on the sampling needle needs to be cleaned . At present, the cleaning methods commonly used in the market are to use flowing liquid to wash away the residual liquid on the pipe wall, or directly use a pressure washing device to wash directly, but only a certain part or angle of the surface of the sampling needle can be cleaned, which is different. To a certain extent, the cleaning is not clean, and the risk of cross-contamination is relatively high. Contents of the invention [0003] The object of the present invention is to at least solve one of t...
