Problems solved by technology

At present, it is more common to use a completely opaque aluminum-plastic composite outer bag or carton for protection. In clinical use, a shading bag, such as a black plastic bag, is required, which is very inconvenient
However, the black plastic bag is unstable under long-term and high-temperature conditions, and it is easy to decompose, which will affect the clinical use of drugs
In addition, the black infusion bag is very inconvenient during clinical use, which is not conducive to medical staff's drug information check and clinical medication observation

Abstract

The invention provides a UV barrier transparent outer bag and a preparation method thereof, which is composed of a polypropylene inner layer, a polyamide middle layer and a polyurethane outer layer, and a barrier ink layer is arranged between the inner layer and the middle layer, and the barrier ink layer It is made by mixing water-based polyurethane resin, plasticizer, n-propyl acetate, UV blocking agent, pigment and connecting material. The UV blocking agent can be an inorganic blocking agent or an organic blocking agent. The transparent outer bag of the present invention is directly covered in In addition to the infusion bag, it is convenient to transport, and also has excellent clinical convenience, can effectively block ultraviolet rays, has excellent mechanical properties and printing properties, and has low production costs.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a UV-blocking transparent outer bag and a preparation method thereof. Background technique [0002] It is inevitable for people to get sick, and intravenous drip is the main means of treating diseases. In the current intravenous infusion process, the medicines that need to be protected from light (light-sensitive), generally use black plastic bags to cover glass bottle infusion, plastic bottle infusion or infusion bags to avoid light. However, for some drugs that are unstable to light (photosensitivity, phototoxicity), corresponding light protection measures should be taken during storage and administration. Therefore, these drugs need to use a light-proof infusion bag during transportation and use, in order to avoid visible light causing related substances (impurities) to increase, reduce drug efficacy, and increase adverse drug reactions to drugs in the infusion bag. ...
