Abstract

The invention provides a blood detection instrument and a sample adding needle cleaning fluid path, the sample adding needle cleaning fluid path is used for cleaning the inner wall and / or the outer wall of a sample adding needle, and the sample adding needle cleaning fluid path comprises a fluid power device, a gating valve, a first fluid suction pipeline, a first fluid pushing pipeline, a second fluid pushing pipeline, a sixth pipeline and a cleaning swab; the first liquid suction pipeline is connected with the liquid power device through a reversing valve; the first liquid pushing pipeline is connected with the sampling needle through the gating valve; the second liquid pushing pipeline is connected with the liquid inlet end of the cleaning swab through the gating valve; the sixth pipeline is connected with the liquid outlet end of the cleaning swab; the liquid power device is used for sucking diluent through the first liquid sucking pipeline; a diluent is transmitted to the sample adding needle through the first liquid pushing pipeline so as to clean the inner wall of the sample adding needle; and diluent is transmitted to the liquid inlet end of the cleaning swab through the second liquid pushing pipeline so as to clean the outer wall of the sampling needle.

Description

technical field [0001] The invention relates to the technical field of medical detection and analysis, in particular to a liquid path for cleaning a sampling needle and a blood testing instrument. Background technique [0002] Blood routine and CRP have become the most common combination in the early diagnosis of infection (outpatient). [0003] Among many symptoms of viral infection such as respiratory tract infection and fever, serum amyloid A (SAA) is a marker that can be significantly increased during viral infection, and has been widely used in infection diagnosis in recent years. [0004] In blood testing instruments, the sampling needle can realize the suction and separation of blood samples, and can also be used to realize the addition of reagents. One needle is dual-purpose, which can effectively improve the speed of sample detection. At the same time, the sampling needle can be used to complete the addition of reagents The action can effectively save the cost of r...
