[0009] A method for using an infusion tube of a medicine dispensing machine comprises the following steps:

[0010] Step 1: First, connect the first connecting piece and the second connecting piece to the two ends of the connecting pipe respectively, then fix the first tip tube and the second tip tube through the connecting pipe through the first connecting piece and the second connecting piece respectively, and connect the regulating valve and the air pressure balance pipe to the outside of the first connecting piece and the second connecting piece respectively;

[0011] Step 2: One end of the connecting tube is connected to the liquid inlet of the first tip tube through the first connecting piece. At the beginning, the first moving block and the second moving block are both on the screw rod. After the motor is started, the screw rod is driven to rotate clockwise, and the first moving block and the second moving block are both moved downward until the second moving block moves to the smooth rod section, and then it abuts against the lower end of the long groove and no longer moves. The first tip tube passes into the first medicine tank, and then the other end of the connecting tube is connected to the output end of the small self-priming pump through the second connecting piece, and the input end of the small self-priming pump is connected to the second medicine tank through the second tip tube;

[0012] Step 3: The motor continues to drive the screw to rotate clockwise, the first moving block continues to move downward, the moving frame moves downward, and the connecting rod drives the two halves of the first pointed tube to open. At this time, the telescopic rod is just completely retracted into the telescopic cylinder, and the small self-priming pump is started to extract the liquid in the second medicine tank through the second pointed tube into the small self-priming pump, and then passes through the second pointed tube in sequence to enter the second connecting piece, the connecting tube, the first connecting piece and the first pointed tube, and finally enters the first medicine tank through the first pointed tube for preparation and mixing; during the transportation process, the regulating valve can be used to adjust the speed of transportation, and the air pressure balance tube can be used to control the air pressure in the connecting tube to achieve balance;

[0016] When the present invention is in use, the first moving block and the second moving block are initially on the screw rod, and the motor drives the screw rod to rotate clockwise, driving the two closed first pointed tubes to be inserted into the first medicine tank. Then, after the second moving block moves to the smooth rod section and abuts against the bottom of the long groove, it stops moving, and the first moving block continues to move downward to drive the two halves of the first pointed tube to open, and fill the first medicine tank with medicine. At this time, the telescopic rod is completely retracted into the telescopic cylinder. After it is filled, the motor drives the screw rod to reverse, and the second moving block moves upward to drive the two halves of the first pointed tube to close, and the medicine liquid retained in the connecting tube will not leak and will not cause waste. After the telescopic rod is completely extended out of the telescopic cylinder, the first moving block moves upward, and the telescopic rod hangs on the telescopic cylinder to drive the second moving block to move upward. The second moving block passes over the smooth rod section and contacts the screw. Subsequently, the second moving block continues to move upward to drive the closed first pointed tube to move upward and disengage from the first medicine tank mouth, and the filling of medicine is completed.
