Blood bag making machine and rotary oral tube feeding device thereof

Abstract

The invention discloses a rotary oral tube feeding device applied to a blood bag making machine. The rotary oral tube feeding device comprises a rotating disc base, a gear and gear ring assembly, rotary supports and electrode pushing assemblies, wherein the rotating disc base is fixed; the gear and gear ring assembly is arranged on the rotating disc base and can be rotated, and the gear and gear ring assembly is arranged in the middle of an annular structure defined by a high-frequency welding assembly and at least two oral tube conveying parts for conveying oral tubes; the rotary supports arearranged on the gear and gear ring assembly, and can rotate synchronously with the gear and gear ring assembly; and the electrode pushing assemblies are arranged on the rotary supports and can be used for pushing electrodes which are used for being sleeved with the oral tubes. The gear and gear ring assembly can be stopped at the positions of the different oral tube conveying parts so that the oral tubes with different sizes can be arranged on the different electrodes in a sleeving manner; and the gear and gear ring assembly can rotate and stop at the position of the high-frequency welding assembly so that the oral tubes can be welded to PVC membrane materials. The invention further discloses the blood bag making machine comprising the rotary oral tube feeding device. According to the rotary oral tube feeding device, efficient and accurate oral tube feeding can be achieved.

Description

technical field [0001] The invention relates to the technical field of blood bag making machines, in particular to a blood bag making machine and a rotating upper tube device. Background technique [0002] As we all know, the blood bag making machine makes two rolls of PVC film through the processes of unfilming, half-cutting, film pulling, spot welding, punching, tube loading, bag opening, high-frequency welding, bag cutting, edge tearing, and outputting. Finished bag. [0003] PVC (polyvinyl chloride) material is currently a common polymer used to make films of IV bags. The PVC material itself is non-toxic, but it may chemically react with medicines, and PVC itself is a brittle substance, so in order to make the PVC transparent and soft, about 40% of the plasticizer DEHP should be added when it is processed into a soft bag. These plasticizers can penetrate into the drug and be absorbed by the body. The accumulation of high amounts of DEHP may lead to precocious puberty ...
