Sealing device

Abstract

The present invention is a sealing device, comprising a body provided with a divisible space; the divisible space is divided into a first partition space and a second partition space by the body; the body is provided with a first body and a second body; The outer side of the first body is covered with a light-shielding material and / or the first body is sandwiched with a light-shielding material; the outer side of the second body is covered with a light-shielding material and / or the second body is sandwiched with a light-shielding material; The gap between the light-shielding material on the first body and the light-shielding material on the second body is provided with a shutter covering at least one side of the gap and exceeding the distance between the gaps. By setting the separation material, it solves the problem that the expected shielded light-decomposable substance reacts with the material in contact with it, resulting in a change in the physical and chemical properties of the light-decomposable substance, and ensures the stability of the light-decomposable substance. Keep light shielding performance good by setting shutters. The invention is used in the field of medical packaging 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
