Convertible multifunctional infusion apparatus
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a convertible multi-functional transfusion system.
Background
Lung cancer is one of the most common cancers worldwide, and data in the global cancer epidemiology database 2020 shows that lung cancer deaths are the first cancer deaths. Intravenous chemotherapy and immunotherapy are one of the main means for treating lung cancer, different infusion sets are required for chemotherapeutic drugs selected by different chemotherapy schemes, and the infusion sets currently used clinically are of a common type, a precise type and a light-shading type. When the common immune medicine is infused, the liquid medicine is filtered by a filter (with the aperture of 0.2 or 0.22 mu m) on a precision infusion apparatus and then is infused into the body of a patient; some chemotherapy drugs have special molecular structures, and absorb light energy under ordinary illumination, so that decomposition, oxidation and other reactions occur, and the curative effect of the drugs is affected, so a light-proof infusion apparatus needs to be used. In the chemotherapy combined immunotherapy process, a precise infusion apparatus and a light-resistant infusion apparatus are required to be combined, or the precise infusion apparatus and a common infusion apparatus are required to be combined, at present, mutual conversion cannot be carried out on one infusion apparatus according to the properties of medicines, so that a nurse needs to replace the infusion apparatus for multiple times to adapt to the medicine properties of different medicines; when the infusion apparatus is replaced, the liquid medicine is easy to waste, a great deal of invariance is caused to clinical work, the nursing workload is increased, and the use is very inconvenient.
