Technical Field
The invention relates to the technical field of medical appliances, in particular to an easy-to-fold combined cover for an infusion container. In addition, the invention also relates to an infusion container comprising the foldable combined cover for the infusion container.
Background
Infusion is a large-dose (more than 50ml per administration) injection that is infused into the body by intravenous drip, and is usually packaged in a glass or plastic infusion container. When in use, the infusion device is used for adjusting the dropping speed, continuously and stably entering the vein to supplement body fluid, electrolyte or provide nutrient substances. Because the dosage is large and the blood is directly fed into the device, the quality requirement is high and the production process requirement is high.
In recent years, research at home and abroad has found that insoluble particles present in a medicinal liquid inevitably enter the human body through intravenous infusion or intravenous injection, thereby causing an acute reaction or potential danger, which is serious and durable. These include mainly vascular embolism, infarction, hemorrhage, granuloma, pulmonary fibrosis, anaphylaxis, cancer reaction, pyrogenic reaction, phlebitis, thrombocytopenia, increased venous pressure, pulmonary arterial hypertension, etc.
The existing transfusion container adopts a large quantity of plastic large transfusion soft bags or bottle packages due to the reasons of labor cost, material cost, production process and the like, and the welded combined cover for the large transfusion soft bags or bottle packages is a passage for contacting a medicine adding needle and a transfusion device (needle) with transfusion liquid medicine in the container, so that the quality of the combined cover directly influences the quality of the transfusion liquid medicine.
The combined cover mainly comprises an outer cover, a rubber plug and an inner cover, and is protected by sealing layer by layer, but a large amount of insoluble particles still exist to generate risks. Firstly, the infusion container, the plastic outer cover and the plastic inner cover are different along with different methods of product design, injection molding manufacture, medicine production process friction, clinic use of puncture needle cutting and the like, and unreasonable structural design of the traditional product, and the repeated test and verification prove that the pollution degree of the generated particles is different; secondly, the rubber plug is mostly a rubber plug, the main component of the rubber plug is synthetic rubber, and the rubber plug also contains sulfur, zinc oxide, carbon ink, talcum powder and the like, and the impurities are easy to fall off to form insoluble particles; and thirdly, the side hole puncture needle and the bevel connection puncture needle with the side holes sequentially penetrate through the rubber plug and the inner cover in the puncture process, and the side hole needle or the bevel connection needle can carry insoluble particles generated by the rubber plug and the inner cover into the infusion solution, so that the insoluble particles of the infusion solution are increased. And the clinical use of the traditional product is characterized in that rubber plug scraps are basically generated when the side hole needle punctures, and the bevel connection needle is basically formed by inner cover plastic scraps.
