阳萎都是因阴茎的动脉供血不足,或静脉不能将血液暂时维持在海绵体内所致的阴茎不能勃起,外部负压装置治疗(External Vacuum Theropy,EVT),就是用器械人为的模仿勃起的发生和维持过移,使阴茎膨胀变硬,能插入阴道而进行性交.早在1917年奥地利Lederero即发明了这类装置,并获得美国专利(NO.1225341).以后又相继有许多设计投入市场,但直到1974年Osbon的产品投入使用才大量被推广,至1984年Virag才首次著文予以评价.目前在美国使用的主要有二大类,即负压缩窄装置(Vacuum Constriction Device,VCD)与“协同”勃起系统(Synergist Erection SystemSES).前者已使用多年,估计全球已有数十万人使用,后者近年才开始使用.
Impotence is due to penile artery insufficiency, or the vein can not temporarily maintain the penis in the blood caused by the erection of the penis, external negative pressure device treatment (External Vacuum Theropy, EVT), is the use of artificial imitation of the device to occur And maintain the shift, so that the penis expansion and harden, can be inserted into the vagina for sexual intercourse.As early as 1917, Austria Lederero invented such devices, and obtained the United States patent (NO.1225341) .And then have many designs into the market, However, it was not until Osborne was introduced in 1974 that it was widely promoted until Virag was first evaluated in 1984. There are currently two major categories used in the United States: Vacuum Constriction Device (VCD) and “ Synergist Erection System SES. ”The former has been used for many years and is estimated to have been used by hundreds of thousands of people around the world, the latter only in recent years.
