Abstract
A triple three-way valve device comprises: a valve body (1) having a distal end and a proximal end, wherein the proximal end of the valve body (1) is connected with a control knob (2) that is radially rotatable relative to the valve body (1); and a valve rod (3) having a distal end and a proximal end, wherein the valve rod (3) is provided within the valve body (1) and is fixedly connected with the control knob (2). The distal end of the valve body (1) is connected with a seat body (4), which is connected with a plurality of liquid passages and a high pressure pipe passage; a selection member (5) provided at the distal end of the valve body (1), wherein, depending on the position of the control knob (2), the selection member (5) selects the communication relationships between the plurality of liquid passages of the seat body (4), the high pressure pipe passage and the valve rod. With the triple three-way valve device, angiocardiography surgery is simplified, and surgery safety and efficiency are improved.
