Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a liquid medicine packaging bag with a suction nozzle. Background Art

[0002] At present, the main packaging materials used for liquid medicine are glass bottles, PVC and non-PVC bottles (bags), among which large-volume injection liquid medicine generally adopts PVC and non-PVC bags. In recent years, due to the increasing concern about the potential harm of PVC materials to the human body, the application of non-PVC composite films has an upward trend.

[0003] An oral liquid medicine packaging bag with a suction nozzle function is disclosed in the Chinese utility model patent application disclosure CN205108387U. Although a silicone suction nozzle is provided on the bag body, it is not only convenient to take, but also can prevent the liquid medicine from spilling out of the packaging bag, and can also isolate the outside air from entering the bag body, and preserve the remaining liquid medicine in the bag body. However, during use, since the straw is long and has a long distance from the bottom of the liquid medicine bag, it is easy for the patient to have difficulty in completely absorbing the liquid medicine in the bag when absorbing the liquid medicine, resulting in a large waste. In addition, there is a certain gap between the sealing cover and the suction nozzle head, which easily causes microorganisms and harmful gases in the air to enter the liquid medicine bag, thereby affecting the quality of the liquid medicine. When absorbing the liquid medicine, the patient may find it difficult to absorb and difficult to handle. Therefore, a liquid medicine packaging bag with a suction nozzle is proposed to solve this problem. Utility Model Content
