ABSTRACT
OBJECTIVES@#To establish an automation system for detection of alcohol content in blood.@*METHODS@#The determination was performed by automated workstation of extraction-headspace gas chromatography （HS-GC）. The blood collection with negative pressure, sealing time of headspace bottle and sample needle were checked and optimized in the abstraction of automation system. The automatic sampling was compared with the manual sampling.@*RESULTS@#The quantitative data obtained by the automated workstation of extraction-HS-GC for alcohol was stable. The relative differences of two parallel samples were less than 5%. The automated extraction was superior to the manual extraction. A good linear relationship was obtained at the alcohol concentration range of 0.1-3.0 mg/mL （r≥0.999） with good repeatability.@*CONCLUSIONS@#The method is simple and quick, with more standard experiment process and accurate experimental data. It eliminates the error from the experimenter and has good repeatability, which can be applied to the qualitative and quantitative detections of alcohol in blood.

OBJECTIVE:To improve automatic outpatient pharmacy drug delivery system in our hospital,and to promote the efficiency of automatic drug delivery. METHODS:The outpatient pharmacy automation system of our hospital was introduced in terms of main structure,working process and application. The work efficiency,safety and error were compared between automatic drug delivery mode and manual drug delivery mode. Drug delivery machine was improved to increase the rate of drug delivery. RE-SULTS:The outpatient pharmacy automation system of our hospital included 2 boxed drug delivery machine and 1 drug dispensing machine,etc. Compared with manual drug delivery mode,automatic drug delivery mode improved drug delivery efficiency,health security and use security,and reduced drug delivery error. Through adjusting the time setting and step of drug delivery of gearing in drug delivery machine,idle time of transmission equipment was utilized effectively,and the quantity of delivered prescriptions was increased,increasing from 220 to 320 each hour. CONCLUSIONS:The reasonable improvement of outpatient pharmacy auto-mation system makes outpatient pharmacy automation system play a bigger role,and further optimize resources.
ABSTRACT
Objective To evaluate the Carryover between the chemistry and immunoassay in Beckman Coulter Laboratory Au-tomation System and decide to whether sharing samples for testing between chemistry and immunoassay systems or not. Methods According to a certain order,high concentration samples and low concentration samples of HCG with different sample volume (500 μl,2 000 μl)were tested on Beckman AU5421 automatic biochemical analyzer.The HCG of low concen-tration samples were then tested to evaluate the carryover between the chemistry and immunoassay and explored the correc-tive procedure to deal with the carryover by increasing special cleaning process of beckman AU5421 automatic biochemistry analyzer.Results Under different sample volume,the carryover in a single module and as a whole of the beckman AU5421 automatic biochemistry analyzer were 5.44,15.47,23.51 and 45.96 ppm respectively (t=14.553,P <0.001;t=5.527,P =0.005;t=3.985,P =0.016;t=20.457,P <0.001).By increasing special cleaning process the carryover of 0.22 ppm was detected in 500 μl sample volume of the beckman AU5421 automatic biochemistry analyzer as a whole.Conclusion The car-ryover between the chemistry and immunoassay in Beckman Coulter Laboratory Automation System could been sovled by in-creasing special cleaning process of beckman AU5421 automatic biochemistry analyzer.
ABSTRACT
BACKGROUND: The automation system for blood typing and antibody screening has been developed and is now used widely. In this study, we evaluated the economic effectiveness between automation system QWALYS-3 (DIAGAST, Loos Cedex, France) and manual testing. METHODS: Clinical samples from March 2012 were used for comparison of the costs and TAT for ABO-RhD blood typing and antibody screening. The costs included those of materials (reagents and consumables), labor, and equipment depreciation. TAT was analyzed for either blood typing only for one, 16, and 32 samples or blood typing and antibody screening for the same number of samples. RESULTS: The blood typing TAT for one, 16, and 32 samples was 4.5, 35.1, and 70.1 minutes by manual and 24.0, 36.0, and 38.1 minutes by automated system. Both blood typing and antibody screening TAT for one, 16, and 32 samples was 27.5, 75.0, and 129.9 minutes by manual and 45.0, 52.0, and 54.0 minutes by automation. CONCLUSION: The blood automation system reduced TAT only for the batch test, therefore, when using the automation system, blood bank test size and emergency situation should be considered.

ABSTRACT
Objective To implement a real-time bidirectional communication function on Siemens StreamLab laboratory automation system, Methods Firstly, the system selecting sample was changed from the default settings and then the communication character string sent by the StreamLab was utilized by the laboratory information system to build up a real-time bidirectional control of the samples assay. Results New functions such as real-time signing in and real-time detection information getting of specimens could be performed by the StreamLab automatically.Conclusion The real-time bidirectional communication between laboratory automation system and laboratory information system can optimize the working flow and improve the work efficiency.
