Description

Technical Field

[0001] The utility model relates to the technical field of infusion covers, in particular to a disposable break-off combined infusion cover. Background Art

[0002] Existing medical infusion glass bottles are sealed with rubber stoppers and aluminum caps. The aluminum caps are expensive and susceptible to squeezing during transportation and storage. Furthermore, aluminum oxides from the aluminum caps can contaminate the rubber inner cap during long-term storage, causing adverse effects. Against this backdrop, with the development of new materials and technologies, plastic infusion bottles have emerged and rapidly developed. Current plastic bottle caps consist of a plastic outer layer wrapped around a rubber gasket. The rubber gasket is large and can be punctured multiple times. If the infusion needle fails to puncture once and then re-punctures the rubber gasket at another location, rubber particles can be mixed into the drug solution through the puncture needle. Once these rubber particles enter the bloodstream along with the drug solution, they can pose a risk to the patient. Furthermore, plastic infusion caps with this structure suffer from high cost, heavy weight, complex manufacturing, and inconvenient transportation.

[0003] In order to solve the above technical problems, the Chinese patent with announcement number CN203075217U in the prior art discloses a disposable break-off combination infusion cap, including a cap body, the cap body including a plastic outer cover, a rubber gasket and a plastic inner cover, the plastic outer cover and the plastic inner cover are both stepped: a pinhole cover is provided in the center of the top surface of the plastic outer cover, and a horizontal columnar handle is connected to one side of the pinhole cover.

[0004] Although the above-mentioned prior art solution prevents the puncture needle on the infusion set from passing through the rubber gasket multiple times, causing rubber particles to be mixed into the medicine solution, when assembling and splicing it, after the plastic outer cover, the plastic inner cover and the rubber gasket are pressed together, the staff still needs to gradually weld the fitting seams of the plastic outer cover and the plastic inner cover, thereby affecting the efficiency of the installation and assembly.
