The above object of the present invention is achieved by the following technical solutions:

a disposable medical medicine tube comprises a soft plastic bag made of HDPE materials and a medical medicine tube, wherein the medical medicine tube is arranged on the soft plastic bag and comprises a joint part, an inhalation tube and a cover body which are integrally formed from bottom to top in sequence; wherein, a through hole facing the soft plastic bag is arranged in the suction pipe and used for the fluid to flow out; a stress notch for separating the cover body from the suction pipe is arranged at the joint of the cover body and the suction pipe, and comprises a cover body retraction part which is arranged at the lower end of the cover body and is recessed towards the inside of the cover body and a suction pipe retraction part which is arranged at the upper end of the suction pipe and is recessed towards the inside of the suction pipe; the upper end of the cover body also comprises a horizontally-arranged 8-shaped twisting head used for assisting in disassembling the cover body.

Further, the wall width from the outer wall to the inner wall at the minimum central circumferential diameter of the stress notch is 0.1 mm.

Furthermore, one end of the suction tube facing the cover body 1 is a fluid suction end, and the top end of the suction tube is also provided with a tapered narrowing for preventing the mouth from being scratched.

Furthermore, the diameter of the central circumference of the straw from the joint of the straw and the cover body is gradually reduced, and the straw is in a cone shape with a central through hole.

Furthermore, the joint part is arranged in the bag body at the upper end of the soft plastic bag in a heat sealing mode, and the joint part further comprises at least one strip buffer layer arranged in the middle of the wall surface of the joint part.

Furthermore, the edge of the twisting head is also provided with a semicircular chamfer used for preventing the hand from being scratched.

The beneficial effects of the utility model reside in that:

the method has the advantages that: the medical drug tube is molded integrally during manufacturing, is different from a spiral split manufacturing process, and saves manpower and material resources required during manufacturing and part matching.

The method has the advantages that: the 8-shaped twisting head which accords with the human engineering and the stress notch which is only 0.1mm are arranged, so that the handle is convenient to hold, stress and disassemble.

The method has the advantages that: different from the packaging of a straw type bag body, the connecting part connected with the bag body has high applicability, and the long buffer layer is combined to improve sealing friction force for matching heat sealing, so that the fixity of the connecting part and the bag body is improved.
