Negative pressure type soft infusion bag

Abstract

The invention discloses a negative pressure type soft infusion bag. According to the manufacturing process steps, material films of inner package bags are sterilized and are merged into a package workshop, the inner package bags are obtained after infusion valves are welded, the inner package bags are filled with liquid medicine, then soft infusion bags are formed, sterilized for the second time and then dried, light inspection is carried out for the first time, unqualified bags with packaging printing errors, welding errors and large impurities are removed, the soft infusion bags are sleeved with outer package bags, negative pressure is pumped between each outer package bag and the corresponding inner package bag, the bags are sterilized for the third time, boxed and placed in a storage to be stored temporarily, then light inspection is carried out for the second time, and leakage bags are removed. By the negative pressure type soft infusion bag, no bacterium can be left in an interlayer, large volume injection with micro-leakage of the inner package bag is conveniently and effectively removed, and the delivery liquid leakage rate is lowered to be below 0.029 per thousand.

Description

[0001] technical field [0002] The invention relates to a medical soft bag transfusion, which belongs to the field of medicine manufacturing. Background technique [0003] Soft bag infusion is a new packaging form of medicinal liquid. Soft bag infusion is a medical drug administration route. The medicinal liquid is filled in the soft infusion bag in an aseptic operation, and then injected into the human body through the vein, so as to achieve the goal of giving drug treatment effect. [0004] Because the medicinal liquid is directly dripped into the veins of the human body, and then reaches the whole body and every organ in the body through the flow of blood. It is self-evident for the health and safety of human life, and will not be discussed here. Ensuring the safety of soft bag infusion (or even the safety of all infusion products) has always been the focus of production, storage, transportation, and use. [0005] The production process of soft bag infusion is summari...

Problems solved by technology

In the actual working process, this light inspection method can find products with microporous liquid leakage, and can detect a large part of the packaging with impurities, obvious welding problems in the packaging, serious damage to packaging materials, and printing defects in packaging, etc. Products with quality problems, and this part of products with obvious quality problems have not been eliminated in advance, which will increase the cost of subsequent temporary storage and transfer work (because this part of products will also be transferred to the production process together with qualified products, which is actually for waste of production resources)

[0010] 3. Because there are too many problems to be inspected in light inspection (including not only picking out micropores and microleakages, but also detecting impurities, welding problems, printing problems, packaging problems, etc.), it will affect the specificity and pass rate of inspection micropores. And it makes the light inspection workers have too many inspect
