Improvement of fluid supplementation system for automatic blood typing and cross matching instrument / 医疗卫生装备

ABSTRACT

Objective To improve the design of the fluid supplementation system of Johnson & Johnson automatic blood typing and cross matching instrument to optimize its working flow.Methods Two polyethylene funnels were placed at the cabinet door to execute drainage,which had the height being 14.6 cm,diameter of the wide mouth being 15 cm,protective lip made of hardboard and volume being 700 ml.Each funnel was connected with a 21-mm-diameter drainage tube whose end was put into a flask full of 0.9％ saline or distilled water respectively.Results The velocity was enhanced efficiently for fluid supplementationn,surface pollution due to liquid splash was avoided,and working comfort and efficiency were increased greatly.Conclusion The improved fluid supplementation system gains advantages in low cost,no pollution and convenience,and thus is worthy promoting practically.
