Double-cavity bag for containing medicine liquid

Abstract

The invention discloses a double-cavity bag for containing medicine liquid, which can adjust the position of a weak welding rod according to medicine liquid amount contained in a medicine liquid inner bag and ensure the quality of a solid welding rod at the periphery of the medicine liquid inner bag. In the double-cavity bag for containing the medicine liquid, the weak welding rod is connected between the upper horizontal section and the lower horizontal section; the length of the upper horizontal section is a1, the length of the lower horizontal section is a2, and the width of the weak welding rod is a3; and a1 is larger than a3, and a2 is larger than a3. The position of the weak welding rod can be adjusted between the upper horizontal section and the lower horizontal section according to the medicine liquid amount contained in two cavities of the medicine liquid inner bag, and therefore, the quality stability of a bag body in the transportation process is ensured; meanwhile, the double-cavity bag can ensure the quality of the solid welding rod at the periphery of the medicine liquid inner bag and prevent the damage of a bag body membrane, caused when the bag body bears an external force, thereby ensuring the quality of the bag body, preventing the leakage of the medicine liquid and being especially suitable for popularization and application in the production and manufacture of the double-cavity bag.

Description

technical field [0001] The invention relates to a medicinal liquid packaging bag, in particular to a double-cavity bag for containing medicinal liquid. Background technique [0002] At present, in clinical practice, when a patient needs to infuse a variety of different infusions at the same time, it is generally adopted to put these various single different products in a sterile dispensing room specially set up in the hospital under aseptic conditions before use. Take out a variety of different single varieties and mix them evenly, and then inject the mixed medicinal liquid into the human body. However, "sterility" is an absolute concept by definition, but unfortunately, in today's highly developed science and technology, absolute sterility can neither be achieved nor verified. Above, this method of mixing increases the chances of the drug being contaminated with microorganisms. At the same time, due to the high construction and operating costs of the aseptic dispensing ro...

Problems solved by technology

When the first medicinal liquid chamber 5 and the second medicinal liquid chamber 7 are filled with certain two medicinal liquids, it is still possible to ensure that the thicknesses of the first medicinal liquid chamber 5 and the second medicinal liquid chamber 7 are consistent, but if the first medicinal liquid chamber 5 1. When other two kinds of medicinal liquids are filled in the second medicinal liquid chamber 7, the thicknesses of the first medicinal liquid chamber 5 and the second medicinal liquid chamber 7 are inconsistent due to changes in the requirements for the amount of medicinal liquid. During the process, the chamber with a higher thickness is easily squeezed, resulting in the opening of the welding rod 2 with a weak arc. The quality of the liquid; in addition, because the welding protruding point 3 is arranged on the inner side of the real welding rod on the upper side of the liquid medicine inner bag, and the protective strip 14 is arranged on the welding protruding point 3, the distance between the protective strip 14 and the welding platform 6 Shorter, resulting in the length of weak arc welding rod 2 is also shorter, easily lead to high temperature, high pressure and unpredictable factors in the transportation process whe
