High-capacity medicine storing and mixing multi-cavity infusion bag

[0032] Such as figure 1 , 2 , 3, and 5, the large-capacity medicine storage mixed multi-cavity infusion bag of the present invention includes an infusion bag 1 and a fluid path device, the fluid path device includes a dosing tube 29-1 and an infusion tube 29; A syringe-shaped drug mixing structure is provided between the infusion bag 1 and the infusion tube 29; the syringe-shaped drug mixing structure is composed of a syringe-shaped outer tube 12 and a piston-type inner tube 18 whose ends are not closed, which are closely matched with it. ;

[0033] The infusion bag 1 is divided into a first chamber 2, a second chamber 3, and a third chamber 6 by two welding lines 5;

[0034] The wall of the barrel-shaped outer tube 12 is provided with a right opening 7 and a left opening 13 symmetrical on both sides. The left opening 13 communicates with the first chamber 2, and the right opening 7 communicates with the third chamber 6, and a needle with a closed top. The cylindrical outer tube 12 c

[0059] Such as figure 1 , 2 , 4, and 5, the large-capacity medicine storage mixed multi-cavity infusion bag of the present invention is shown in Example 1.

[0060] The needle-shaped outer tube opening includes a circular imaginary tangent line 19 on the lower surface of the top end of the needle-shaped outer tube 12, and an arc-shaped protruding thorn 21 is extended on the top end of the piston-type inner tube 18 -1, the arc-shaped thorn 21-1 corresponds to the ring-shaped virtual tangent line 19.

[0061] When in use, the piston-type inner tube 18 moves, the arc-shaped protruding thorn 21-1 pierces the ring-shaped virtual tangent line 19, and the second chamber 3 and the piston-type inner tube 18 form a channel, and the medicine can be mixed or added along this channel.

[0063] Such as figure 1 , 2 , 4, and 5, the large-capacity medicine storage mixed multi-cavity infusion bag of the present invention is shown in Example 1.

[0064] The second chamber 3 of the infusion bag 1 is provided with an upper end adding port 29-1, so that it can be added flexibly and conveniently in the second chamber 3, which has different physical and chemical properties from the first and third chambers 6. medicine.
