Abstract: Objective To evaluate the effectiveness and safety of new wearable pneumatic compression pump in preventing deep vein thrombosis．Methods One hundred and fifty-six patients with cerebral infarction were randomly divided into control and study group with 78 cases in each group．Study group was treated with the new wearable pneumatic compression pump（Bangpu Medical / VW100）．Control group was treated with pneumatic compression pump（Wonjin-POWER）．The course of both groups was 10 days,comparing the deep vein thrombosis rate and useage satisfaction of patients and staffs between the two groups．Results After 10 days of treatment,the difference between the incidence of deep venous thrombosis in the study and control group was 1.2%．The corresponding 95% confidence interval was（-5.3%,7.9%）,and the lower limit was greater than -10%．The appraisal from medical staffs and the patients of study group was better than that of the control group（P<0.001）．Conclusions The clinical effect of the new wearable pneumatic compression pump to prevent deep vein thrombosis is not inferior to the existing pneumatic compression pump,which clinical practice experience is better．There is no obvious adverse reactions in the treatment process,and the clinical practice is also safe and effective．
