External barrier bag infusion bag

Abstract

The invention discloses a transfusion bag with an external isolating bag. The space between an internal packaging bag and an external packaging bag is vacuumized; a plurality of longitudinal grooves are formed in the internal wall of the external packaging bag; a plurality of transverse grooves are formed in the external surface of the internal packaging bag; a vacuum degree indicator is also arranged in the external packaging bag; a transfusion pipe inserting opening is pre-set in a rubber plug; and the transfusion pipe inserting opening consists of a guiding opening and a sealing seam. By virtue of the grooves formed in the internal surface of the external packaging bag and the external surface of the internal packaging bag, an air-flowing path net is formed in a longitudinal and transverse staggered manner; a relatively high negative pressure value in a transfusion valve is uniformly transferred to each place in the packaging bag to form equal negative pressure values, so that micro leakage holes in the internal packaging bag can be displayed rapidly in a detailed manner; the vacuum indicator is low in manufacturing cost and can well represent the current vacuum degree in the bag; when the transfusion pipe guiding pipe is inserted, the guiding pipe is opened through the elasticity of the rubber without causing damage of the rubber plug so as to prevent from slag dropping; and the invention provides the safer transfusion product for medical cause and can guarantee health of patients.

Description

technical field [0001] The invention specifically relates to a large transfusion preparation for medical use, in particular to a transfusion bag filled with five layers of co-extruded film outside the composite bag. Background technique [0002] Large infusion preparations are what we often call infusion, and the finished product is also called infusion bag, which directly infuses the built-in medicinal solution into the human vein. [0003] The infusion bag is a soft plastic bag. In some cases, the infusion bag may be slightly damaged, which is called microleakage. Micro-leakage has a long hidden period, and the leak hole is extremely small but enough to allow bacteria to enter the liquid medicine. And because the liquid in the infusion bag does not obviously pass through the micropores, it is invisible to the naked eye. Produced the infusion bag of bacterial contamination and has great potential safety hazard. [0004] In order to solve the above problems, the patent (2...

AI Technical Summary

Problems solved by technology

[0005] 1. Even if the amount of leakage increases and accelerates, the leakage is transparent liquid, which is still not obvious in the transparent packaging

[0006] 2. When vacuuming between the inner and outer bags, since the packaging film is a smooth surface, during the rapid vacuum extraction process, the mouth of the packaging is first drawn by the vacuum machine so that the inner and outer packaging fit together, blocking the place farther away from the mouth of the packaging The air in the bag is successfully pumped away, resulting in local bubbles between the inner and outer bags, and the vacuum pressure of each part between the inner and outer bags is unbalanced; the effect on accelerating the increase in leakage is not obvious

However, the current technology cannot evenly transfer the higher negative pressure value at the infusion valve to all places in the packaging bag.

[0007] 3. When vacuuming the inner and outer bags, the vacuum degree set by the vacuum machine is often unable to actually act on the specific product, or when the outer packaging is damaged, the air will enter between the inner and outer bags, making the extracted vacuum Invalid, the set vacuum degree cannot be reached, but whether it reaches the set vacuum degree cannot be known by naked eyes, and it is impossible to test the vacuum degree of each bag of product

[0008] In addition, the infusion valve of the infusion package is provided with a rubber stopper, and the infusion catheter must be used to pierce the infusion rubber stopper to insert the infusion valve into the infusion during infusion. grains, and entered into the infusion, and finally entered into the human body, bringing uneasy factors
