Embodiment Construction

[0018] Such as figure 1 , 2 . The integrated multi-channel anti-backflow plug valve shown in 3 includes a valve body 1 and several three-way plug valve units 2 installed on the valve body 1. The two ends of the valve body 1 are respectively provided with a first interface and a second interface. The valve body at the three-way plug valve unit 2 is provided with a plug valve interface 3 perpendicular to the first interface and the second interface. The plug valve interface 3 includes a valve inner sleeve 31 and a valve outer sleeve 32, and the valve inner sleeve 31 is installed on the valve body. In the body interface groove 33, the valve outer sleeve 32 is installed outside the valve inner sleeve 31, and a frustum hole 34 is set on the valve body 1 between the valve body interface groove 33 and the three-way cock valve unit 2, and a frustum hole 34 is set inside the valve body interface groove 33. Cone plug 35.

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.

Description

technical field [0001] The invention relates to an integrated multi-channel anti-backflow plug valve, which belongs to the technical field of plug valves. Background technique [0002] The function of the multi-channel stopcock is to allow or block communication between drugs or liquids when injecting drugs or liquids into the patient's body. Existing multi-channel stopcocks are mainly designed for intravenous infusion. The ports on both sides are connected to infusion sets and needles, and multiple ports on the lower part are connected to extension tubes to realize infusion of different drugs and liquids. Installed on the pipeline of infusion (blood) equipment or other medical equipment, it is used as a multi-channel infusion switch for various infusion (blood) equipment and for converting medicinal liquid delivery. [0003] For example, the application number 201520134030.1 is a multi-channel stopcock valve for a one-time use infusion set with precision filter. One port ...
