Sealing device

Abstract

The invention relates to a sealing device. The sealing device includes a body provided with a space which can be divided; the space which can be divided is divided into a first divided space and a second divided space through the body; the outer side of the body is covered with light shielding materials and / or the light shielding materials are clipped to the body; the sealing device is provided with a shield machine at the gap between the light shielding materials, wherein the shield machine at least shields one side of the gap and exceeds the gap length; at least one layer of separation material is arranged between the light shielding materials and a pre-shielding easily photo-decomposed material, the problem that the pre-shielding easily photo-decomposed material is easily reacted with other materials in contact with the pre-shielding easily photo-decomposed material and the physical and chemical properties of the easily photo-decomposed material are easily changed is solved, and the stability of the easily photo-decomposed material is ensured. The shield machine is arranged at the gap between the light shielding materials, the problem that light enters from the gap and photodecomposition of the easily photo-decomposed material is caused is solved, and the light shielding performance is kept well. The device is applied to the field of medical packing materials.

Description

technical field [0001] The invention relates to the field of medical packaging materials, in particular to a sealing device. Background technique [0002] In daily life, it is often necessary to use light-proof materials to separate and store some special materials (such as light-decomposable drugs, reagents, formulations, and materials, etc.), infusion therapy, and transshipment. Clinically, some drugs have poor stability and are prone to reactions such as oxidation, decomposition, and discoloration when exposed to light after dissolution; some chemotherapeutic drugs may undergo complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, oxidation, and isomerization after dissolution. Light can catalyze the process of the above reaction. However, when the light-shielding material is in direct contact with light-decomposable substances, the physical and chemical properties of the drug or material are often affected or other chemical reactions occur....

AI Technical Summary

Problems solved by technology

Clinically, some drugs have poor stability and are prone to reactions such as oxidation, decomposition, and discoloration when exposed to light after dissolution; some chemotherapeutic drugs may undergo complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, oxidation, and isomerization after dissolution. Light can catalyze the process of the above reaction

However, when the light-shielding material is in direct contact with light-decomposable substances, it will often affect the physical and chemical properties of the drug or material or cause other chemical reactions.

[0003] There are gaps between the light-shielding materials in the current light-proof products, so that light can enter the inside of the light-proof products through the gaps, and the light-proof performance is reduced
