A medical laboratory clinical biochemical detection automatic checking method and system

The invention provides a medical laboratory clinical biochemical detection automatic checking method and system. The method employs a computer software and hardware system and programs multiple checking rules to form a multiple checking rule execution module to automatically check the detection results of various biochemical immunity detection items. The detection results of the various biochemical immunity detection items cannot be sent to an automatic checking unit for automatic checking until they pass the multiple checking rules; if the detection results of the various biochemical immunity detection items cannot pass the above-mentioned checking rules, the detection results are transferred to a manual checking unit for checking; only after the detection results are checked by the manual checking unit or checked again after automatic treatment of dilution, reexamination, test item adding, unqualified sample return and the like by an assembly line can a detection report be issued; the multiple checking rules mainly include a clinical information judging rule, a sample state judging rule, an indoor quality control judging rule, an instrument state judging rule, a range judging rule, a difference judging rule, and a logical relationship judging rule. The checking rules are reasonable in design and cover the pre-analysis, analysis and post-analysis processes, thereby realizing whole-process quality control on a detection analysis process and guaranteeing the accuracy of detection results.

Method and system for intelligently identifying and reading immunity-chromatography test strip and application thereof

The invention discloses a method an a system for intelligently identifying and reading an immunity-chromatography test strip and application thereof. The method comprises the following steps that: the immunity-chromatography test strip with a bar code is arranged in a test strip test jack; light emitted by a light source in a bar code identification circuit is irradiated on the bar code of the immunity-chromatography test strip with the bar code by a lens; the emitted light is converted into an electric signal by a photoelectric converter; the signal is transmitted to a CPU by an amplification and rectification circuit; and the CUP fetches an analysis programme corresponding the type of the immunity-chromatography test strip with the bar code according to the received electric signal from the bar code identification circuit. The system obtained according to the method has high intelligent degree and simple operation. The operator only needs to insert the immunity-chromatography test strip with the bar code in a designated position of the device and then makes a loading end of the immunity-chromatography test strip in contact with a sample so as to know the result of the test item by a display screen.
