Abstract
The invention relates to a positive-pressure pinch valve which comprises a front guide pipe, a pipe sac, a clip and a back guide pipe. The positive-pressure pinch valve is characterized in that the front guide pipe and the back guide pipe are respectively bonded on outlets at both ends of the pipe sac; and the pipe sac is arranged in an internal space defined by the clip. In the liquid infusion process, the positive-pressure pinch valve is arranged on a retained pipeline; after the infusion process is finished and the connection with the retained part is cancelled, the clip is compressed by hand, so that a protruding tongue on the clip and a fastener are fastened together; meanwhile, two pressure plates on the clip, extending towards the internal space of the clip, forcedly reduce the internal space of a spherical sac on the pipe sac until the internal space is pinched off; and at this moment, liquid in the spherical sac flows in a treatment direction so as to form a positive pressure. When the positive-pressure pinch valve is reused, the spherical sac can automatically recover the smoothness of the infusion pipeline under the action of the own elasticity of the spherical sac by simply unclosing the clip.
