Abstract
The invention provides an integral multi-channel backflow prevention plug valve, which includes a valve body and a plurality of three-way plug valve units which are installed on the valve body. A first interface and a second interface are formed in both ends of the valve body correspondingly, plug valve interfaces perpendicular to the first interface and the second interface are formed in the valve bodies of the three-way plug valve units, the plug valve interfaces include a valve inner sleeve and a valve outer sleeve, the valve inner sleeve is installed in a valve body interface groove, the valve outer sleeve is installed outside the valve inner sleeve, a frustum hole is formed in a valve body between the valve body interface groove and the three-way plug valve units, and a frustum plug is arranged in the frustum hole. The plug valve is easy and convenient to use, a backflow prevention mechanism is arranged in a tee, and thus using is safer; and since both functions of a multi-channelcock and a backflow prevention valve are achieved, and especially when multi-channel infusion is needed in clinical ICU, multi-channel parallel infusion, single-channel infusion and multi-point infusion can be realized.
