Cleaning system for blood coagulation analyzer

Abstract

The invention relates to a cleaning system for a blood coagulation analyzer. The cleaning system is used for cleaning a sample needle and a reagent needle in the blood coagulation analyzer, and the cleaning system comprises a cleaning liquid barrel used for storing cleaning liquid, a plurality of cleaning stations. and a plurality of first pumps, the number of the first pumps corresponds to that of the cleaning stations, and each first pump is used for conveying the cleaning liquid in the cleaning liquid barrel to the corresponding cleaning station and conveying the cleaning liquid in the cleaning liquid barrel to the top end of the corresponding sample needle and / or reagent needle; wherein the cleaning liquid conveyed into the cleaning stations is used for cleaning the outer wall of the sample needle or the reagent needle, and the cleaning liquid conveyed to the top end of the sample needle and / or the reagent needle is used for cleaning the inner wall of the sample needle and / or the reagent needle. The inner walls and the outer walls of the sample needle and the reagent needle can be cleaned, and the situation that the accuracy of next test is affected by residues of samples and reagents is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, the invention relates to a cleaning system for a coagulation analyzer. Background technique [0002] In the existing coagulation analyzer, each test involves different samples and reagents. After the sample needle and reagent needle are used, there will be samples or reagents on the outer and inner walls. If they are not cleaned, the next test will be affected. Therefore, a solution that can clean the sample needle and the reagent needle is needed. [0003] The information disclosed in the Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or in any way to suggest that this information forms the prior art that is already known to a person skilled in the art. Contents of the invention [0004] In view of the above problems, the present invention is proposed to p...
