[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0017] like Figure 1 and Figure 2 As shown, a one-piece medical rubber stopper includes a rubber stopper 2 arranged on an infusion bottle 7, the lower end of the rubber stopper 2 is provided with an inflow channel 6 connected to the bottle mouth of the infusion bottle 7 and used for the inflow of liquid medicine, the upper end of the rubber stopper 2 is provided with an outflow channel 5 for the outflow of liquid medicine, both sides of the rubber stopper 2 are provided with connecting channels 3 for the circulation of liquid medicine, and the connecting channel 3 is also provided with a regulator for sealing or opening the connecting channel 3 by sliding left and right to isolate or connect adjacent infusion bottles 7, and the upper end of the rubber stopper 2 is provided with a rubber tube 1 for the outflow of liquid medicine.

[0018] The bottom end of the infusion bottle 7 is provided with a hook for hanging.

[0019] The inner diameter of the inner cavity of the outflow channel 5 is in a decreasing shape to facilitate the slow outflow of the drug solution.

[0020] By arranging flow channels with four directions for the flow of the liquid medicine inside the rubber stopper 2, the circulation of the liquid medicine can be achieved without additional pipes or needles, thereby reducing pollution in the air.

[0021] The regulator includes an inner magnet 9 arranged on the connecting channel 3 of the rubber stopper 2, an outer sleeve 8 sliding on the surface of the rubber stopper 2 and cooperating with the inner magnet 9 so that the inner magnet 9 slides in the connecting channel 3, and an annular protrusion 11 arranged on the rubber stopper 2 and distributed on both sides of the outer sleeve 8 for limiting the extreme position of the outer sleeve 8.

[0022] The annular protrusion 11 is at a left limit position and a right limit position, respectively, for limiting the positions of the outer sleeve 8 and the inner magnet 9.

[0023] By manually moving the outer sleeve 8 so that the outer sleeve 8 and the inner magnet 9 are magnetically attracted to each other and the position of the inner magnet 9 is moved, the liquid medicine of different infusion bottles 7 can be circulated, thereby realizing the use of multiple infusion bottles 7 in an integrated manner.

[0024] The inner magnet 9 is elliptical in shape, and cooperates with the stepped connecting passage 3 to block the flow passage of the connecting passage 3 .

[0025] The outer surface of the inner magnet 9 is provided with a rubber outer skin 13 for preventing contamination of the liquid medicine and playing an isolating role, and the outer sleeve 8 is provided with a magnet block magnetically matched with the inner magnet 9 .

[0026] The inner cavity of the communication channel 3 is in a stepped shape to cooperate with the inner magnet 9 to facilitate the outflow of the liquid medicine.

[0027] A cover plate 10 is provided at the end of the communication channel 3 of the rubber stopper 2 for sealing when the infusion bottle 7 is not in use; a connecting rubber tube 4 for connecting the rubber stopper 2 is provided between adjacent infusion bottles 7 .
