2 results about "Cross matching" patented technology

The application discloses a risk assessment system for cross matching difficulty, and relates to the technical field of clinical medical examination and blood transfusion management. The system comprises a data input module, a risk calculation module, a risk stratification module and a result output and suggestion module. The data input module obtains key information of a patient, including irregular red blood cell antibody screening results, multiple myeloma diagnosis, hematology department medical history, age of 60 years or older, pregnancy-related disease state and blood type identification difficulty; the risk calculation module adopts a preset scoring algorithm to assign weights to each factor and calculate a total risk score; the risk stratification module divides the patient into three grades of low risk, medium risk and high risk; and the result output module provides a differentiated clinical management path corresponding to the risk grade. The application realizes early warning of cross matching difficulty through quantitative assessment, can optimize the efficiency of the blood transfusion process and reduce clinical risk, has good prediction performance (AUC=0.819) and a high negative predictive value (93.7%).

The utility model discloses a reagent classification storage frame special for blood transfusion laboratory, reagent classification storage frame special for blood transfusion laboratory includes setting on the first storage area of base, second storage area, third storage area and fourth storage area, set at least one first installation groove for the installation irregular antibody screening cell reagent on the first storage area, set at least one second installation groove for the installation blood type reverse type reagent on the second storage area, set at least one third installation groove for the installation blood type positive type and Rh (D) blood type type reagent on the third storage area, and the fourth storage area is provided with the fourth installation groove for the installation agglutination amine cross matching blood reagent, the utility model discloses four storage areas and sets up the installation groove of corresponding specification reasonably, realizes the orderly classification and fixed placement of reagent, effectively avoids the risk of reagent bottle falling and taking confusion, simultaneously, through the corresponding design of name mark and installation groove, further improves the accuracy and efficiency of reagent taking.
