Filling method of soft bag transfusion products

Abstract

The invention belongs to the technical field of medical product production and particularly provides a filling method of soft bag transfusion products. An adopted filling machine comprises a case, anair cylinder and a conveying column. Supporting columns are fixedly connected to four top corner positions of the upper surface of the case correspondingly. The same first fixing block is fixedly connected between the two supporting columns on the left side together. The same second fixing block is fixedly connected between the two supporting columns on the right side together. Sliding blocks areconnected to the front and the rear of the side faces of the opposite sides of the first fixing block and the second fixing block in a sliding manner. The same conveying column is connected between the two sliding blocks together in a rotating manner. In the initial state, inserting columns distributed uniformly are fixedly connected to the front end face of the conveying column. According to thefilling method, automatic liquid medicine filling is achieved effectively, the problem of disqualification due to filling overflowing is reduced, and meanwhile, the time period for preserving liquid medicine in transfusion bags can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of medical product production, in particular to a method for filling soft bag transfusion products. Background technique [0002] The packaging containers of existing infusion products mainly include several commonly used types such as glass bottles, hard plastic bottles and soft bags made of plastic materials. Among them, the glass bottles need to continuously introduce air into the glass bottles through the ventilation pipeline during the infusion process, resulting in Pollutants such as dust in the air enter the glass bottle and cause drug pollution; hard plastic bottles are also relatively hard, and ventilation pipes are still needed, so they have the same defects as glass bottles; soft bags only pass through the external atmospheric pressure. It can make the liquid in the bag output without introducing air, and the material is transparent and easy to use, so it is more and more widely used in current me...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the filling machine cannot effectively discharge the gas inside the infusion bag when filling the infusion bag with liquid medicine in the prior art, and there is no gas guide mechanism, so it cannot be cleaned before filling the liquid medicine. The infusion bag is pre-expanded, so when the inner wall of the infusion bag sticks, the injected medicinal liquid will overflow due to insufficient storage space, resulting in poor filling and other problems. The invention proposes a filling method for soft bag infusion products
